Phase I: Territorial Sovereignty and Scope of Dispute

CHAPTER VII – Evidences of the Display of Functions of State and Governmental Authority

Analysis of the Evidence

239. The factual evidence of "effectivités" presented to the Tribunal by both parties is voluminous in quantity but is sparse in useful content. This is doubtless owing to the inhospitability of the Islands themselves and the relative meagreness of their human history. The modern international law of the acquisition (or attribution) of territory generally requires that there be: an intentional display of power and authority over the territory, by the exercise of jurisdiction and state functions, on a continuous and peaceful basis. The latter two criteria are tempered to suit the nature of the territory and the size of its population, if any. The facts alleged by Eritrea and Yemen in the present case must be measured against these tests, with the following qualification. Not only were these islands for long uninhabited and ungoverned or, if at all, governed in the most attenuated sense, but the facts on which Eritrea relies were acts by its predecessor, Ethiopia, which were not "peaceful", unless that term may here be understood to include acts in prosecution of a civil war. Nevertheless, the Tribunal cannot discount these facts, given the singular circumstances of this case.

240. The Tribunal has found it useful to classify the wide variety of factual evidence advanced by the Parties in relation to this subject, and will now examine these categories of evidence in turn.

Assertion of Intention to Claim the Islands

241. Evidence of intention to claim the Islands à titre de souverain is an essential element of the process of consolidation of title. That intention can be evidenced by showing a public claim of right or assertion of sovereignty to the Islands as well as legislative acts openly seeking to regulate activity on the Islands. The Tribunal notes that the evidence submitted by both Parties is replete with assertions of sovereignty and jurisdiction that fail to mention any islands whatsoever, and with general references to "the islands" with no further specificity.

Public Claims to Sovereignty over the Islands

242. Eritrea's claim that these islands were included as part of "the former Italian colony of Eritrea" by the Italian Military Armistice of 1943, the 1947 Treaty of Peace, and the 1952 Constitution is barely supported by evidence. It is true that Italy wished to claim the islands and indeed established a presence on some of them; but these facts were always subject to repeated assurances that the islands' legal position was indeterminate in accordance with Article 16 of the Treaty of Lausanne and with the Rome Conversations (see Chapter V, above). The 1952 Eritrean Constitution defined the extent of Eritrean territory as "including the islands," but failed to specify which islands were intended. The same uncertainty existed in the language of Article 2 of the United Nations Resolution approving the 1952 Constitution, the 1955 Ethiopian Constitution, the 1987 revision of the Ethiopian Constitution, and the 1997 Constitution of the newly-independent State of Eritrea.

243. The scant evidence of Ethiopian legislation before the Tribunal suffers from the same uncertainty as do the constitutional provisions. The 1953 Ethiopian Federal Crimes Proclamation and a 1953 Maritime Order put in evidence by Eritrea were not explicit about the Islands. The former was content merely to specify "any island which may be considered as appertaining to Ethiopia," and the latter simply republished the phrase "including the islands." A Maritime Proclamation of 1953 referred merely to "the coasts of the Ethiopian islands."

244. Seventeen years later, in 1970, Ethiopia promulgated an order for a state of emergency. This Order did not specify the Islands; nor did the implementing regulations promulgated by the Minister of National Defence. Three 1971 operations orders are cited by Eritrea to demonstrate that "the islands in dispute here fell within the ambit of Ethiopia's concern". They identify Greater Hanish and Jabal Zuqar as being "areas" to be visited or as reference points for patrol routes. In 1987, the Ethiopian Ministry of National Defence was given responsibility "for the defence of the country's territorial waters and islands" but, again, those "islands" remained unidentified.

245. In 1973, the Ministry of Foreign Affairs of the Yemen Arab Republic informed the Imperial Ethiopian Embassy in Sanaa of the YAR's plans to conduct a full aerial survey of its territory that would cover certain "Yemeni islands." These were identified as: "Great Hanish", "Little Hanish", "Jabal Zuqur", "Jabal al Zair", "Jabal Zal Tair", and "Humar". The reason given for the notification was that the photographs, which were to be take from a height of 30,000 feet, might show "parts of the Ethiopian coasts". Ethiopia responded that "some of the islands listed in the afore-mentioned note could not be identified under the nomenclature used, while others are Ethiopian islands." This exchange of correspondence is cited in a January 1977 "Top Secret" memorandum of the Ministry of Foreign Affairs of The Provisional Military Government of Socialist Ethiopia, which details the measures Ethiopia considered taking to protect its interests. The memorandum refers to islands in the southern part of the Red Sea that "have had no recognized owner", with respect to which Ethiopia "claims jurisdiction"(19) and "both North and South Yemen have started to make claims." It names the Hanish islands, Jabal Zuqar, Jabal al-Tayr and Jabal Zubayr, and points out that the 1973 response to the YAR had deliberately been left vague, because there was insufficient time to collect evidence in support of Ethiopia's "claim over the islands" and for fear of provoking a military response from Yemen and its Arab allies, particularly in the wake of false reports, in 1973, of an Israeli presence on certain Red Sea islands. The memorandum urges that "Ethiopia . . . take a clear stand in this respect in order to protect its ownership."

246. Yemen relies on a claim of historic title, asserted to stem from time immemorial. It was allegedly most early evidenced in 1429, when King al-Zahir of Yemen sent a mission to Jabal Zuqar to investigate two vessels engaged in smuggling that had run aground on the island. The relevance of this happening is vigorously contested by Eritrea on various grounds which were not responded to in substance by Yemen. It appears to be unique, and isolated. The Tribunal does not consider it important in relation to the determination of title to Zuqar. Its only significance (which has been substantially weakened by Eritrea's rebuttal of its relevance, not replied to by Yemen) might be that it could support an interpretation of the Imam's aspirations so as to include at least Jabal Zuqar, but that in turn fails since there is no evidence that when he advanced his claim of historic rights in 1918, the Imam knew of the 1429 expedition. Moreover, the source for that information was only published in 1976, long after the claim of historic rights had allegedly been advanced by the Imam.

247. In his reply to a British proposal for a treaty of friendship, the Imam is recorded as having requested, inter alia, "(2) Establishment of his rule and independence over all the Yemen, i.e., over that part which was once under the sway of his predecessors. . . ." This claim could not have been more general. Indeed, the word "that part," being expressed in the singular, would not seem naturally applicable to islands. This generalized claim was apparently manifested on several occasions in bilateral diplomatic conversations during the inter-War period, but no constitutional or legislative act of Yemen or of the Imam claimed any of the Islands specifically or described them specifically as Yemeni territory.

248. Yemen asserted in the oral hearings that in 1933: ". . . certain British representatives expressed puzzlement as to why the Imam was so adamant about his claim to the islands of Al-Yemen, including the islands of the Hanish Group." The Yemeni Foreign Minister allegedly "made the Imam's claim to the Hanish Islands well known to German officials in 1930, France in 1936 and, of course, England, in connection with the 1934 treaty and on many other occasions." Yemen added that "the Imam stated and restated his historic claims to the British, to the French and to the Italians whenever this was practically possible", and this appears to be borne out by contemporaneous evidence from 1930 to 1936.

249. Other evidence of communications between the Imam and British diplomats, including the records of the Clayton mission of 1926, and Colonel Reilly's communications to the Foreign Office are too vague to serve as evidence of a specific claim by the Imam to the Islands at that time.

250. Although Yemen asserted in the oral hearings that Yemen's response to the granting of an oil concession by the United Kingdom in the area of Kamaran Island in 1956 "restated the claim to the Red Sea Islands", the language actually used in the official statement merely stated that "[t]he Yemeni Government considers Kamaran island and the other Yemeni islands to be a inseparable part of Yemen". It also added that "[t]he Yemeni Government continues to insist upon its rights to the Yemeni islands and their liberation." A likely inference to be drawn from this is that the "islands" referred to could not have been the islands now in question since those were not islands that required "liberation".

251. In 1973 there were press reports that Israel had occupied Jabal Zuqar with the permission of Ethiopia. Substantial effort was devoted by both sides in the proceedings to seeking to demonstrate that the respective reactions to the matter were relevant to sovereignty over the Islands. A 1973 press statement issued by the Embassy of the Yemen Arab Republic in Mogadishu reported that Yemeni investigations had found "Lesser Hanash, Greater Hanash, Zukar, Alzubair, Alswabe and several other islands at the Yemeni coast", to be free of foreign infiltration, and further stated that:

[ . . . ]

The Y.A.R. always controls and maintains its sovereignty over its islands at the Red Sea, with the exception of the islands of Gabal Abu Ali and Gabal Attair which were given to Ethiopia by Britain when the latter left Aden and surrendered power in our Southern Yemen.

This supports an inference that the phrase "its islands in the Red Sea" included the disputed Islands; moreover, the press statement emphasized that the Yemen Arab Republic maintained its claim of sovereignty over those islands "given by Britain to Ethiopia," and urged Ethiopia to surrender those islands.

252. Yemen's "historic claim" was initially expressed in vague and general terms following the end of World War I, and reiterated in bilateral diplomatic contexts in the inter-War period. After World War II it was reasserted in 1956, even though largely in doubtful and indirect terms. In 1973, however, it was expressly revived in a public statement (which, although it said that Jabal al-Tayr and the Zubayr group had been "given to Ethiopia," also reasserted Yemen's "rights and possession" to them and was specific about the other, "mentioned," islands). The statement therefore left little room for doubt that Yemen had sustained or renewed its claim over all of the larger Islands, including the northern islands - or, at any rate, as of 1973. There is no evidence that Yemen subsequently abandoned or relinquished this claim. The evidence does, however, also suggest that Yemen had no presence on and little knowledge about Jabal al-Tayr and the Zubayr group at that time, and supposed that they were in the possession of Ethiopia. The fact was that, for many years, the northern lighthouses were administered from Ethiopia by employees of the lighthouse company.

Legislative Acts Seeking to Regulate Activity on the Islands

253. There is no evidence of post-war Ethiopian legislation seeking expressly to regulate activity on the Islands. As discussed above, no Ethiopian legislation between 1953 and 1992 specifically purported to exercise jurisdiction and state functions over the Islands. From 1992 to the inception of the dispute in 1995, no Eritrean legislation explicitly treated the Islands as being subject to the jurisdiction and control of Eritrea.

254. The Ethiopian Federal Crimes Proclamation and the 1953 Maritime Order put in evidence by Eritrea were not explicit. They applied to "any island which may be considered as appertaining to Ethiopia" and "the islands." A related Maritime Proclamation of 1953 referred merely to "the coasts of the Ethiopian islands." These instruments would of course have applied to the Dahlak group and to the islands in the Bay of Assab; but those islands are not disputed.

255. As to Yemen, the evidence of administrative and legislative decrees advanced to support a claim of the exercise of state functions follows substantially the same pattern as the evidence introduced by Ethiopia: there is silence as to whether the Islands are intended to be included in the ambit of the decrees. There is no evidence of Yemeni legislation openly seeking to regulate activity on the Islands. From 1923 to the inception of the dispute in 1995, no Yemeni legislation specifically treated the Islands as being subject to the jurisdiction and control of Yemen.

256. In 1967, two decrees were issued by the President of the Yemen Arab Republic concerning territorial waters and continental shelf. However these did not mention the Islands by name. Yemen contends that the subsequent Yemeni licensing in 1987 of a research program in waters off the Islands by the German research vessel, the F.S. Meteor, demonstrated their applicability to the Islands. While that is unclear, it is arguable that this incident can be viewed as crystallizing Yemeni intent as to the scope of the 1967 legislation.

257. In conclusion, the evidence on behalf of both Parties shows legislative and constitutional acts without any specific reference to the Islands by name. It should be borne in mind that during most of these years both Ethiopia and Yemen were distracted by civil war or strife, and serious internal instability. Yemen did not resile from the broad and loose claims made before World War II - which might or might not have embraced the islands in dispute - but did not pursue or articulate them until 1973.

Activities Relating to the Water

Licensing of Activities in the Waters Off the Islands

258. There is much evidence that Ethiopian naval units had for many years conducted surveillance in the Red Sea and in particular around the Zuqar/Hanish archipelago. As pointed out below, it is not clear whether those actions were evidence of fisheries control and administration or whether they primarily related to security measures, or both, particularly in light of the fierce struggle by the Eritrean freedom fighters in the two decades prior to Eritrean independence. In any event, there is little evidence that the Ethiopian activity was based on fisheries regulations or laws as such.

259. As to Eritrea, the evidence only dates from early 1992. In January of that year the Eritrean provisional government issued a notice prohibiting in general terms unlicenced fishing activity in "Eritrean territorial waters". Eritrea has asserted that its Ministry of Marine Resources "has regulated fishing in Eritrean waters since shortly after Eritrean independence." On 1 April 1995, the Ministry of Marine Resources issued a "Manual and Guidelines for the Administration of Foreing [sic] Vessel Licensing and Operations."

260. In September 1995, Trawler Regulation I was issued by the Ministry of Marine Resources. The statement is made by Eritrea that the handout appended to Trawler Regulation I "includes the Zuqar-Hanish islands within Areas No. 11 and 12 (Beilul and Berá isole)."(20) The areas are separated laterally by dotted lines. These lines do not however extend to, or surround, the Zuqar/Hanish archipelago. (Comparison with Maps 1 and 2 shows, in the case of Map 2's depiction of the Dahlak ("Dehalak") archipelago, a carefully-drawn lateral boundary around the Dahlaks.)

261. As far as Yemen is concerned, there is no evidence of any regulation or order as such regulating fisheries as such in Yemeni waters. The evidentiary record is devoid of any assertion of a formal legal basis for fisheries jurisdiction assumed by the Yemeni Government over the waters surrounding the Zuqar/Hanish archipelago. A witness statement cited in support of the proposition that Yemeni Government "launches are vigilant in controlling illegal fishing" merely details that the witness (a Navy Captain) "was assigned by [his] . . . command to arrest foreign fishermen pirates . . . who were looting our maritime wealth in a random and illegal manner," but indicates no further detail.(21)

262. Yet Yemen has asserted that it has "tightly regulated fishing activities on and around the Hanish Islands" and that "the Government has actively controlled illegal fishing." There is a substantial record of fishing vessel arrests by Yemeni authorities between 1987 and 1990. It should be noted however that they are recent in time, and appear to have been primarily directed in recent years against large Egyptian industrial fishing vessels.

263. In conclusion, the Tribunal is of the view that the activities of the Parties in relation to the regulation of fishing allows no clear legal conclusion to be drawn. The record of these activities under Ethiopian administration is, as will be seen below, open to conjecture. Since Eritrean independence, the record is less than clear. Since 1987, Yemen appears to have been engaged in some regulation of fishing, primarily directed toward larger vessels. The balance of this evidence does not appear to tilt in one direction or another.

Fishing Vessel Arrests

264. Although there is evidence before the Tribunal that a substantial number of arrests of fishing vessels for violation of the respective fishing regulations and orders have occurred, the period of time comprised in that evidence is brief. It is difficult therefore to characterize those actions as the "continuous and peaceful display of state authority."

265. The evidence before the Tribunal concerning Ethiopian regulation of fishing or fishing violation arrests is almost wholly derived from former Ethiopian naval officers. There are many detailed witness statements that recount service in the Ethiopian patrolling forces during the Eritrean war of independence In most instances the whereabouts of particular incidents are rendered in general terms, albeit with frequent reference in particular to islands of the Zuqar/Hanish archipelago. Although there are few dates given for the various vessel arrests referred to in the witness statements, the majority of activities reported appear to have taken place during the two decades preceding Eritrean independence in 1991.

266. A fair reading of the witness statements shows that by far the principal concern of the Ethiopian military during this period was to combat the EPLF activities on and around the Islands and to deny the use of the Islands to rebel forces either as a staging area for strikes on to the Eritrean coast of Ethiopia or as supply depots and strategic bases. The Ethiopian naval officers concerned did also exercise police powers when they would stop and check fishing boats.

267. The primary purpose of such an exercise was suppression of the insurgency. In most of these cases the witnesses stated that part of their duties was to stop all fishing boats and check their papers and cargo. Thus, "[t]he Dankali fishermen were suspected of cooperating with the rebels in smuggling arms, ammunition and other supplies across the Red Sea." However the duties of these naval patrols also extended to keeping foreign fishermen out of what Ethiopia considered to be her territorial waters. Vessels that were not licensed to fish in the waters or that were of non-Ethiopian registration were arrested or requested to leave.

268. The Eritrean pleadings state that the evidence shows "the inspection of fishing and/or commercial vessels as a primary function of their routine patrols around the islands." Having regard to the fierce fighting that was going on over the years in question in and around the area in question, it is not clear that enforcing fishing regulations was the primary purpose of these Ethiopian naval patrols.

269. At the same time, the Tribunal is not disposed to discount the evidence introduced by Eritrea on the grounds that the acts were not "peaceful". Military action taken in a civil war is in any event not normally regarded as a belligerent act that would have no legal relevance for the question of title. Accordingly, even though the Tribunal does not accept Eritrea's contention that most activity was directed at fishing regulation, the Tribunal finds nonetheless that they are not without legal significance.

270. In 1976, an Ethiopian naval patrol boat arrested three Yemeni fishermen on Greater Hanish Island. Yemen protested to the United Nations Security Council this "flagrant act of aggression and . . .distinct violation of the sovereignty of the Yemen Arab Republic." Ethiopia responded, in a formal letter from its UN Permanent Representative to the President of the Security Council, that "[t]he Ethiopian patrol boats were carrying out their responsibilities within Ethiopian jurisdiction."

271. Following independence, the record shows that much attention became devoted to control of Eritrean fisheries affairs, entailing inter alia a number of vessel arrests, some of which involved Yemeni fishermen. Although a substantial number of witness statements speak of supervisory authority and activity by Ministry of Marine Resources authorities in conjunction with the Eritrean Navy, the evidence dates from the time of Eritrean independence and in almost all instances relates to matters occurring after 1995. Without precise fixing of coordinates and distances, it is unfortunately difficult to see whether the activities and vessel arrests in question actually occurred with respect to the waters around the Zuqar/Hanish archipelago or Jabal al-Tayr and the Zubayr group. Many witness statements and reports are not clear as to how close to the contested islands the incidents were.

272. As to Yemen, a number of incidents between 1987 and 1995 are also in evidence. There is documentary evidence of an arrest in 1989 of an Egyptian trawler "next to Zuqar island . . . in the territorial waters of Yemen". There is also testimony from a Navy Captain that in May 1995 he was assigned "to arrest foreign fishermen pirates" and that he arrested "several launches" of "Gulf ownership" with Egyptian crews after a gun battle "in Yemeni territorial waters," "in an area between al-Jah and Zuqar". Although Yemen asserted that in 1990 four Egyptian fishing vessels were arrested "in the area of the Hanish Group", and the owners required to pay an indemnity to Yemen and undertake not to repeat their actions, the supporting document does not specify the location of the arrests.

273. However, a 1990 report addressed to the Yemeni Defence Ministry describes twenty separate incidents between 1987 and 1990 in which a total of more than sixty vessels are reported to have been arrested, accosted, "escorted to" a naval base, or "warned to leave" - a good number of these incidents appear to have related to Egyptian commercial fishing vessels. While some of these are described as having been in the vicinity of the Zuqar/Hanish archipelago or Jabal al-Tayr, Zubayr and Abu Ali, the report refers to the "area of" a named island or islands; one exception is a report of unlicenced fishing by two Egyptian trawlers "at Zuqar". In most instances, when vessels were ordered to leave, the report states that the warnings specified that they should depart "from territorial waters" or "from Yemeni waters".

Other Licensing Activity

274. Apart from fishing, there have been no attempts on the part of Eritrea to demonstrate any licensing activities in respect of the waters off the Islands. For its part, Yemen asserts the official approval in 1993 of plans for a tourist boat operation between al-Khawkha and Greater Hanish. There was also a license granted by Yemen to a German company for the building of a diving centre on the north end of Greater Hanish in 1995. As will be discussed below, between 1972 and 1993 the Yemeni Government recorded eight instances of requests for approval for activities relating to the use of the waters around the Islands, and in several cases approval was given for research and diving expeditions and the like.

Granting of Permission to Cruise Around or to Land on the Islands

275. As discussed, there is an abundance of evidence before the Tribunal relating to the manifold activities of the Ethiopian Navy in the 20-year period before Eritrean independence. That evidence largely indicates that the Ethiopian naval patrols operated intensive patrolling in and around the Islands during the Ethiopian war against the Eritrean insurgents. In that role, the naval vessels stopped ships, boats and dhows in those waters, requested identification and inspected equipment and cargo. Tourist vessels anchored near the Zuqar-Hanish islands were arrested and brought into Ethiopian ports for investigation and the film from their cameras was destroyed.

276. There is evidence that informal requests from third parties for permission to cruise around, anchor at or land on the Islands were sometimes made to naval patrols. For example, one witness statement indicates that radio requests made to Ethiopian patrol craft to anchor "at the north western cove off Hanish," received from "large foreign commercial vessels" (including ones of Greek, Japanese, Yugoslavian and Italian nationality), were granted for reasons such as "repairs, shelter or rest."

277. As to Yemen, there is evidence that in 1978 three Kuwaiti fishing trawlers requested and received shelter from a storm at Jabal Zuqar, and that on two occasions in 1991 foreign flag vessels sought and received permission to anchor at Zuqar and Hanish for repairs.

278. In addition, between 1972 and 1995 Yemen received at least eight formal requests from third parties, including one from a foreign Government, for permission to cruise around, anchor at, or land on the Islands: A request from an Italian organization to conduct research on Jabal Zuqar was declined by the Government of the Yemen Arab Republic in 1972; the French Government in 1975 requested permission to conduct naval exercises in the vicinity of the Hanish Islands; in 1983 a request from a French organization to film submarine life was approved; in 1987, a German request for scientific research studies to be conducted by the F.S. Meteor around the Hanish Islands was approved by an official governmental decree and the project was completed without incident; for indeed The Meteor seemingly carefully avoided the territorial waters of both Ethiopia and Yemen. In 1992 approval was given for a diving trip by a British yacht, the Lady Jenny V, around the Islands; in 1993 the Yemen Government approved a research expedition to the Zuqar/Hanish archipelago to be conducted with the Royal Geographical Society; in 1993, the Government approved the French research expedition of the Ardoukoba Society to Greater Hanish, and also approved a German diving expedition on the yacht Cormoran. There is also an unsupported statement that a Polish request for diving in the area was rejected in late 1995.

279. It should be noted however that there is no specification of the islands in the application or report of the cruise of the Meteor though the Report mentions the Hanish Islands and states that "maximum values were noted at the Hanish Islands..." Moreover, the terms of the license specified that the "research operation must be conducted in waters at a depth of 100 meters or more", thus excluding research in any close proximity to the Islands.

280. What can be concluded is that there was somewhat greater Yemeni activity than Ethiopian/Eritrean activity in the granting of permission relating to the Islands in the periods stated.

Publication of Notices to Mariners or Pilotage Instructions Relating to the Waters of the Islands

281. Other than Eritrea's fishing regulations, Eritrea has produced no evidence of publication, by Ethiopia or by Eritrea, of general information concerning pilotage or maritime safety.

282. In the five years between 1987 and 1991 Yemen published six Notices to Mariners in connection with its installation of new lighthouses in the Islands. These were: Centre Peak (1987 and 1988); and Jabal Zuqar (1989). Following the 1989 London Conference on Red Sea Lights, Yemen issued a Notice to Mariners concerning a new solar lighthouse on Jabal al-Tayr, and one concerning a new system on Abu Ali. In 1991 the Yemen Ports Authority constructed a new lighthouse on Low Island, and an official telex notification was sent to the Hydrographer of the Royal Navy in Taunton (referring to it as "Hanish as Saghir" Island). In 1992 a similar telex was sent indicating a "beaconpipe" at "Jabal-at-Tair", a lighthouse at "Sawabey" (al-Zubayr), a lighthouse at Abu Ali, a beacon at Zuqar, and beacons at Hanish Sashir and Hanish Kabir.

283. The Tribunal notes that such notices form a natural adjunct to the operation and maintenance of lighthouses, but that latter function, in the particular circumstances of the Red Sea, does not generally have legal significance. The issuance of such notices, while not dispositive of the title, nevertheless supposes a presence and knowledge of location. Moreover, it is to be noted that in relation to these indications, accuracy in identifying the navigational aid and its location is of the prime importance, rather than the provenance of the information.

Search and Rescue Operations

284. Eritrea has produced evidence maintaining that in 1974, the M.V. Star of Shaddia was stranded off Zubayr. There is no evidence as to her nationality. HMS Ethiopia attempted a rescue, but was unable to approach the ship because of severe weather and mechanical difficulties, and departed without being able to assist.

285. In 1990, the Yemeni Ports Authority rescued an Iraqi vessel, the Basra Sun, from the rocky coast of Jabal Zuqar after it had requested assistance.

286. Since there is under the law of the sea a generalized duty incumbent on any person or vessel in a position to render assistance to vessels in distress, no legal conclusions can be drawn from these events.

The Maintenance of Naval and Coast Guard Patrols in the Waters Around the Islands

287. Eritrea has produced a large amount of evidence relating to naval patrolling activity in and around the Islands. The activities alleged are for the most part not referred to in documentary evidence, but rather in affidavits prepared in connection with these proceedings. However, the Tribunal takes note of statements by Eritrea that a large amount of Ethiopian naval records were destroyed in the course of hostilities.

288. 1953-1973: For the first twenty-year period (1953-1973), Eritrea has introduced two types of evidence: naval logbooks from 1959-1967 and naval operations reports primarily from the 1970s.

289. Naval logbooks: The Eritrean Memorial states that "there are numerous records that the Islands were 'visited and/or observed'"(Eritrean Memorial, p. 427), implying that most of the logs indicate this. It also states that they "demonstrate in painstaking detail the continuous Ethiopian presence in the disputed islands" and characterizes them as "record[ing] visits" to the Islands.

290. However, the logs themselves - in contrast with the operations reports - relating to the years 1959, 1961, 1962, 1963, and 1967, do not use the word "visit." Moreover, it is not clear to the Tribunal what that term entailed. The "observations" are largely contained in Column (13) of the standard printed logbook form, labelled "Soundings Fixes Bearings Observations," and a study of the entries in that column shows that they are almost uniformly position "fixes" of azimuth bearings on land points and islands, sometimes from as far as fifteen miles offshore.(22) The Tribunal cannot therefore draw many useful conclusions about Ethiopian exercise of governmental functions with respect to the Islands on the basis of these logs alone.

291. Operations reports and orders: Eritrea has placed in evidence three operations reports - two cruises in April 1970 and one in July 1971. However, the language in which the missions are recorded in the operations reports is too vague to be relied upon as establishing state functions with respect to the Islands in this case, e.g., patrolling the "area south" of Greater Hanish and the Haycocks, sailing "to Grand Hanish and back," and investigating vessels "south of Zuqar" and "vicinity Jebel Attair." The only relevant precision accorded by this evidence is in the operation report of HMS Ethiopia for July 20/21 and 25/26, where she "[a]nchored Zuqar" overnight in order to remedy mechanical difficulties. Episodes of that nature can hardly give rise to a legal claim of occupation and control.

292. Furthermore, although the Eritrean Memorial captions its description of the reports with a statement that they demonstrate the "continuous Ethiopian naval presence around the disputed islands," for the twenty years in question they cover only two cruises in April 1970 and one cruise in July 1971. In consequence, these documents hardly support the assertion that the Ethiopian Navy maintained a "continuous presence" around the Islands for the entire period of 1953-1973.

293. There are also in evidence four operations orders of the Ethiopian Navy, from January, July, September and October of 1971. They instructed the preparation of "a Schedule" for visiting the different areas," including "Kebir Hanish" and "Zukar", and patrols "around Hanish I[s]lands", "within the route: Dumeira is - Fatmah Lt. - Rs Darma - Kabir Hanish - Zuqar - Edd and Ras Darma", and another with a similar routing. They cover less than one year out of twenty, though this may be explained by the asserted destruction of Ethiopian naval records during the civil war. In warfare continuing over several decades, it does not seem likely that Ethiopian activity in controlling insurgency would be limited to a single year.

294. 1974-1980: Eritrea has also put forward documentary evidence of a similar nature relating to activities from 1974 up until the end of 1980, but this is just as sparse as that for the preceding twenty years. Again, it takes the form of log-books and orders which, being contemporaneous, have a special interest, as well as correspondence. The log-book entries, for 1974, 1977 and 1980 reveal the same kind of imprecision as the earlier log-book records, one of which, for example, while purporting to "record . . . [a] visit . . . to Hanish (on August 16) [1977]", merely shows "Hanish" in the Column (13) of the Log under "Soundings Fixes Bearings Observations" as having been sighted by P-203 at 0400 on August 16th, at a bearing of 325° and at a distance of 20 n.m. This is not evidence of a "visit", nor of passage through the territorial sea of that island.

295. Additional evidence has been presented describing the Ethiopian/Eritrean sea battle off the island of Zuqar after the capture of the merchant ship Salvatore by the ELF on the way to Assab in June 1979, but it is not clear what evidentiary relevance can be ascribed to this incident. Finally, P-203's Log-Book in May 1980 records warning shots at a Canadian and a West German boat; the precise location is not indicated in the log but the incident is noted in an entry which begins "slipped out for patrolling Hanish to Zuqar". The 1980 capture of five wooden boats referred to in the pleadings is not particularized further than occurring "near the islands of Lesser Hanish." In April 1980 some Yemeni fishermen were captured "near Zuqar Island," and others were also captured "in the vicinity of the Zuqar/Hanish islands." This incident was in fact protested by North Yemen.

296. Eritrea states that the "most critical Ethiopian naval event of 1980" was "Operation Julia"; and that it "resulted in twenty four hour surveillance and a blockade of the entire area for the entire three month period of the operation". When the map submitted in evidence is consulted, it shows what appear to be four areas of patrolling off the Ethiopian/Eritrean coast: two close on shore, one half-way to Greater Hanish from the coast, and one lying approximately 3-4 n.m. west of Near Island and Shark Island on the west side of Jabal Zuqar, and running south across Tongue Island to just north of Marescaux Rock. The context of Operation Julia shows quite clearly that this was a series of grave incidents at sea between the Ethiopian naval forces and the rebel forces, and that the Ethiopian naval forces patrolled their own coastlines, and the sea mainly west of the Islands facing the Eritrean coast; a main purpose of the operation having been to stop rebels "infiltrating into Assab District".

297. 1973-1993: For the second twenty-year period, Eritrea has also placed substantial evidence before the Tribunal, largely in the form of seven witness statements specially obtained from seven former Ethiopian navy officers and two witness statements obtained from two former EPLF naval fighters. With one exception, the testimony relates only to activities from 1968 on. The testimony, summarized in the written pleadings, largely concerns activities at sea extending over substantial periods between 1964 and 1991.

298. It is however possible only to rely on this testimony for the most general of indications. In ten out of the thirty incidents described by Eritrea the identity of the Ethiopian or Eritrean vessel is not given. The dates of the incidents are given in only nine cases. Their locations are specified in only three, but in those three instances the time frame extends over indeterminate periods of eight months, five years, and one month respectively. There is therefore no evidence of an arrest or stopping by Ethiopian or Eritrean naval forces with both a precise location and a precise date, for the entire period from 1970-1995.

299. In a close reading of the witness statements provided by Eritrea, three other interesting points emerge with clarity which should assist in evaluating the context and scope of this evidence. These points have not been controverted in the proceedings.

300. The first point is that out of the seven witness statements of former Ethiopian naval officers, three record no landings on the Islands. The remaining four are imprecise with respect to either date or location. There are two witness statements that mention more than isolated landings during the entire period from 1973-1993.

301. The second point relates to the nature of the patrols which, as well as being fast, appear to have taken place at night, and sometimes in conditions of darken ship. These factors bear upon the absence of protest by Yemen.

302. Third, although some of the evidence does recite that the "purpose of these patrols was primarily to apprehend vessels carrying contraband and to keep foreign fishermen, who were generally from Yemen, out of our territorial waters", it is not clear that a major twenty-year military operation increasing in intensity can be viewed as primarily related to fishing. There is certainly some validity to the argument that checking fishing boats on a regular basis was an essential part of checking for insurgents and contraband weapons. Just as checking ELF dhows for small arms and ammunition was essential to defeating the rebels ("[t]he dhows could carry hundreds of sheep and goats, so they would hide the supplies underneath the livestock where it was impossible or us to search") so was checking fishermen (" . . . we would often see Dankali fishermen further east, in the area of the islands . . . . We would check the identification papers for the boat, captain and crew and look for contraband and armaments.") However, normal fisheries surveillance does not require checking for "contraband and armaments".

303. There also appears to be, in this evidence, a discrepancy in Eritrean witness statements as to the presence of Yemeni fishermen. While some witnesses state that "Yemeni fishermen were almost never reported to be in the area of Zuqar and Hanish at this time" (the late 1980's) and "I never encountered a Yemeni fishermen [sic] in the waters around Zuqar and Hanish", others state: "[w]e patrolled east of the Dahlaks as well as the Hanish islands" and "[s]ometimes, our patrols would find Yemeni fishermen fishing in Ethiopian waters, including around Zuqar/Hanish."

304. 1983-1991: These witness statements were also intended to supplement the documentary evidence put in by Eritrea as to activities from 1983 through 1991 but this evidence is imprecise. Speaking almost consistently in terms such as "around Hanish and Zuqar," "the environs of Hanish," "in the vicinity of Jabal A'Tair," these operations and reports and sailing orders are sparse chronologically: May 1983, October 1984, September 1984, May 1986, July 1984, and August 1987. Even if this evidence were precise as to location and relevance to the Islands, it could still hardly provide a demonstration of a "continuous Ethiopian naval presence around the disputed islands" as it covers only six months out of ninety-six and leaves out four years entirely of that continuous naval presence.

305. Nevertheless, the extent of this evidence and its homogeneity do suggest the conclusion that the Ethiopian Navy, during the period in question, did in fact conduct widespread surveillance and military reconnaissance activities in the waters around the islands. It is uncontroverted that these patrols were frequent and, in the course of the Ethiopian war against the ELF and the EPLF, of steadily increasing intensity. Elements of the Ethiopian Navy anchored frequently off the Islands, sent details ashore for reconnaissance missions, and even bombarded suspected rebel facilities on the Islands.

306. With the exception of the 1976 incident discussed above (which was protested to the Security Council of the United Nations), North Yemen (and, later, the Republic of Yemen) did not protest any of these Ethiopian naval activities. Although such a lack of protest would normally appear to suggest a degree of acquiescence, four elements need to be weighed by the Tribunal in considering the evidence: the location of the Islands, the fact that they were not settled, and the fact that there was no normal line of communication from persons on or near the Islands to the mainland; the fact that many of the Ethiopian patrols appear to have been conducted at night under conditions of darken ship; the fact that many of those patrols were conducted at high speed; and the fact that civil hostilities were in progress.

307. At the same time, the failure of Yemen to protest the considerable presence of Ethiopian naval forces around and sporadically on the Islands over a period of years is capable of other interpretations. If Yemen did not know of that presence, that belies Yemeni claims that there were Yemeni settlements of fishermen on the Islands and that Yemen patrolled the waters of the Islands and indeed maintained garrisons on them. If Yemen did know of this Ethiopian presence, and if, as the record shows, did not protest it, that could be interpreted as an indication that Yemen did not regard itself as having sovereignty over the Islands, or, at any rate, as an acknowledgment by Yemen that it lacked effective control over them.

308. Yemen could take the view that belligerent acts by Ethiopia against insurgents using the Islands were not elements of continuous and peaceful occupation by Ethiopia, or that Ethiopian regulation of Yemeni fishing vessels found within the waters of the Islands was incidental to Ethiopian belligerency. But such acts, belligerent or otherwise, could not normally be reconciled with Yemeni sovereignty over the Islands. Thus, if Ethiopia's naval presence in the Islands over the years does not establish Ethiopia's (and hence Eritrea's) title, it may nonetheless be seen as throwing into question the title of Yemen.

309. The Tribunal has found it necessary to address at some length the Eritrean evidence relating to naval patrolling over a substantial period of time. At the same time it must be noted that Yemen has not suggested to the Tribunal that it conducted more than a very few activities during this entire period of naval operations by Ethiopia. Yemen has not explained its lack of protest.

310. Essentially Yemen relies on two witness statements. In one statement, Yemen asserts that patrols of the Islands were "carried out on a regular basis" - weekly in the summer and "once every month or two" in the winter but the dates are unspecified. A specific date, but a very recent one, is given by this statement for an assignment "to arrest foreign fishermen pirates" (May 1995). This statement also tells of intercepting foreign warships (American, French and Russian) "in these islands" and requesting them to leave, but no dates are supplied except for an incident with a Russian merchant vessel "on the western side of Zuqar off of Shaykh Ghuthayyan about 1977-78." Interception of an ELF dhow between Zuqar and al-Jah was recorded "about 1974-75."

311. In the other statement, evidence is given that "during the years of 1965 to 1977" the Yemeni naval forces carried out regular patrols around the Islands, saying that "[t]hey always anchored at the anchorages of these islands and patrolled around them" (specifying the anchorages by name), and that "[o]ur soldiers and officers would land onto their shores." The statement adds, without specifying dates, that "[m]any times our officers and naval enlisted personnel would land on the shores of those islands (Zuqar, Greater Hanish, Lesser Hanish, and al-Zubayr) on dismounted reconnaissance missions (on foot), as well as to swim and relax." The period is not specified other than generally from 1965 to 1977.

Environmental Protection

312. Yemen reports having investigated an oil spill reported by a Russian freighter about 10 miles from Lesser Hanish in 1990.

Fishing Activities by Private Persons

313. There was substantial debate between the Parties as to whose fishing community was more important, and as to how important a part fishing and fish played in the economic life of each state. The Tribunal does not find these arguments pertinent, since in any event it may be expected that population, and economic realities, will change inevitably over time. What may be very important today in terms of fishing may be unimportant tomorrow, and the reverse is also true.

314. For Eritrea, the evidence before the Tribunal includes the statement that "[t]here are more than 2,500 Eritrean fishermen, many of whom are artisanal fishermen engaged in small-scale fishing using traditional methods and equipment" and that "[t]he waters around the Zuqar-Hanish islands supply a significant portion of Eritrea's annual catch." For Yemen, the statement has been made that: "[f]ishing communities along the Yemeni Red Sea coast have historically depended on the neighbouring islands of the Hanish Group for their economic livelihood."

315. Numerous witness statements were submitted by both sides as to the longevity and importance of their respective fishing practices and the significance of fishing in the lives of their people. Yet, although substantial evidence of individual fishing practices in the record may be taken as a different form of "effectivité" - i.e., one expressive of the generally effective attitude and practice of individual citizens of Eritrea or of Yemen - it is not indicative as such of state activity supporting a claim for administration and control of the Islands. This varied and interesting evidence, on both sides, speaks eloquently concerning the apparent long attachment of the populations of each coast to the fisheries in and around the Islands, and in particular that around the Zuqar-Hanish islands. However it does not constitute evidence of effectivités for the simple reason that none of these functions are acts à titre de souverain. For state activity capable of establishing a claim for sovereignty, the Tribunal must look to the state licensing and enforcement activities concerning fishing described above.

316. Yemen has put into evidence a substantial number of arrests of commercial fishing vessels in the past few years in the waters around the Islands. These arrests have been accompanied by legal proceedings, expulsion of the vessels from the waters, and substantial fines. The arrested vessels appear to have borne foreign registries other than Ethiopian or Eritrean and in most cases seem to have been Egyptian. No protests of these activities have been recorded from Ethiopia or Eritrea. Eritrea also produced a witness who related that "between 1992 and 1993" while a commercial captain in the Zuqar-Hanish waters he reported about 20 Egyptian trawlers. "Some of these trawlers were confiscated..." He further stated that in his job at the Department of Marine Transport it is his current responsibility "to determine what should be done with them."

Other Jurisdictional Acts Concerning Incidents at Sea

317. A lost dhow was searched for off the Islands, and an investigation conducted by Yemeni authorities in 1976; a drowning at sea at Greater Hanish was investigated by Yemeni authorities in 1992.

*  - *

Activities on the Islands

318. In order to examine the performance of jurisdictional acts on the Islands, the Tribunal must consider evidence of activities on the land territory of the Islands as well as acts in the water surrounding the Islands. This evidence includes: landing parties on the Islands; the establishment of military posts on the Islands; the construction and maintenance of facilities on the Islands; the licensing of activities on the land of the Islands; the exercise of criminal or civil jurisdiction in respect of happenings on the Islands; the construction or maintenance of lighthouses; the granting of oil concessions; and limited life and settlement on the Islands.

Landing Parties on the Islands

319. The direct evidence presented shows little or no landing activities on the Islands by either side.

320. Eritrea's evidence shows that during the twenty years of the emergency there was substantial activity onshore and off the Islands by elements of the Ethiopian navy engaged in suppressing the secessionist movements. The record indicates clearly that the Islands were used heavily by rebel forces in connection with their war of independence. As discussed above, in the context of naval operations around the Islands, two substantial patrols and a number of unspecified landing parties by Ethiopian military forces are in evidence for the period between 1970 and 1988.

321. On the part of Yemen, there was an official visit to Jabal Zuqar and the Abu Ali Islands in 1973 following the publicity about possible Israeli presence on those islands. In response to the Tribunal's request for specific information, the Secretary-General wrote to the President of the Tribunal on 28 July 1998, informing him that there had never been "any visit to any of the islands in the red sea by any official delegation of the League of Arab States headed by the secretary general." The letter reported a 1973 meeting between the Secretary General of the Arab League and the Ethiopian foreign minister, to discuss Arab concern about reports of Israeli use of the Dahlak islands and other islands in the bay of Assab. The Ethiopians invited an Arab League delegation to visit the islands in order to confirm that there was no Israeli presence, "but no such visit was ever made." Finally, the Arab League letter states that "in 1971 and 1973, members of the League of Arab States' military committee, including yemeni officers, visited the islands of the hanish group including zuqar as well as the zubair islands with the sole cooperation and assistance of the Governments of the People's Republic of Yemen and the Yemen Arab Republic." According to the Secretary General, no report of these visits had been found in the League's archives.

322. Other Yemeni assertions of military presence on the Islands rely heavily on one witness statement describing unspecified landings over a period of time with unspecified dates, other than generally from 1965 to 1977.

323. Yemen has also placed into evidence information concerning field trips by faculty and students of the Staff and Command College in 1987 and 1990. It does not appear that the trips were for more than a very brief period of time, or left any lasting effects.

Establishment of Military Posts on the Islands

324. The evidence presented shows no permanent military posts on the Islands before 1995. Although Eritrea's statements include the mention of landing parties, it was explained that no garrison had been established and the relevance of such garrisons was denied. Rather, Eritrea emphasized that what was legally relevant were sovereign acts tailored to the character of the territory in question, namely military surveillance and fishing regulation.

325. As to Yemen, although the written pleadings state that "a temporary military garrison" was "established . . . on Jabal Zuqar at the time of" the 1973 visit, and that "[d]uring the 1970s, the Government placed guard posts on other islands in the Group, including on Greater Hanish", no evidence was submitted to substantiate that statement. Photographs introduced into the record of groups of military personnel standing on the Island do not give the impression of permanence. It is also to be noted that no structure or building is shown in the photographs; one would have expected that, had there been any structure or building available, it would have been captured on film.

326. The Tribunal concludes that it cannot accept that a permanent garrison or military post was established on the Islands until following the outbreak of the dispute in 1995.

Construction and Maintenance of Facilities on the Islands

327. There is no evidence of the construction or maintenance of any type of facilities on the Islands by Eritrea. Eritrea nevertheless claims, as an indication of Ethiopia's "consolidation of sovereign control over the disputed islands," that following the hand-over of Aden in 1967 the lighthouses on Abu Ali and Jabal al-Tayr were managed by a private company then based on Asmara, and that Ethiopian regulations applied to transactions by that company in connection with its management and maintenance of those lighthouses. The Tribunal does not consider this to be persuasive.

328. Yemen has however constructed some lighthouses and has maintained others. The operation or maintenance of lighthouses and navigational aids is normally connected to the preservation of safe navigation, and not normally taken as a test of sovereignty. Maintenance on these islands of lighthouses by British and Italian companies and authorities gave rise to no sovereign claims or conclusions. The relevance of these activities and of Yemen's presence at the 1989 Red Sea Lights Conference are examined in Chapter VI.

329. Yemen also points to the siting and installation of two geodetic stations by French companies in 1992 on behalf of the Yemeni Government on Jabal Zuqar and Greater Hanish as examples of state action. Eritrea's response is that these markers were placed secretly and are in any event modest. The Tribunal cannot give too much weight to such small monuments of this nature, and yet must also note that in fact the markers were installed before the exchange of correspondence between the two heads of state in 1995; that they do exist; and that they are reflected on a map of geodetic stations in the Yemen.

330. The maintenance of shrines and holy places that was also presented in Yemen's materials appears to be of a private nature; no governmental activity is suggested. There is unsubstantiated testimony before the Tribunal that "[o]ur government built an airfield between al-Shura and al-Habal [on Greater Hanish] for helicopters." The airstrip constructed by Total on Greater Hanish with Yemen's authorization in relation to the 1985 Total concession and subsequently dedicated to rest and recreational visits by Total employees is discussed in Chapter IX.

331. Although evidence concerning the intentions in May 1995 of the Yemeni General Investment Authority is recent, and although such indications are only of state action without specific object, it nevertheless demonstrates that on a high governmental level the Yemeni authorities were seriously considering that investment should be encouraged for tourism on Greater Hanish, Lesser Hanish, Abu Ali, Jabal al-Tayr and al-Zubayr; thus official government policy implicitly relied on Yemeni sovereignty over these Islands at that time.

Licensing of Activities on the Land of the Islands

332. Eritrea has suggested that the fact that authorization was required for the private firm Savon & Ries to ship radio transmitters to Abu Ali and Jabal al-Tayr, the islands on which that firm maintained lighthouses, was indicative of the exercise of state control. However the regulation of electronic equipment used by a private firm whose personnel were operating in a zone in which military activities were conducted cannot be viewed as an exercise of sovereign authority with respect to the land territory of the islands concerned.

333. Eritrea has produced evidence of the grant of a licence for the operation of a radio transmitting station on Greater Hanish in connection with petroleum activities to be conducted in the vicinity.

334. As to Yemen, discussion follows concerning its construction and maintenance of lighthouses on the Islands. To the extent that most of the useful economic activity and interest in the Islands is generated by their position in the Red Sea and by their relationship to their surrounding waters (whether for purposes of smuggling, fishing, or tourism), most of the licensing activities that have taken place have all been water-related. One brief but not insignificant use of the land resources on the Islands that was also water-related was the recent amphibious scientific research expedition of the Ardoukoba Society to Greater Hanish, authorized by Yemen.

Exercise of Criminal or Civil Jurisdiction in Respect of Happenings on the Islands

335. In 1976, a military court of the Ethiopian Government conducted a trial of employees of Savon & Ries, the lighthouse maintenance company servicing the lights on Abu Ali and Jabal al-Tayr, on accusations of leading and training a subversive group on those islands. The resulting execution of the finance officer and expulsion or imprisonment of a head lighthouse keeper and others caused the company to move its offices from Asmara to Djibouti.

336. The examples of contemporary exercises of criminal jurisdiction over matters occurring in the Islands by Yemeni authorities include a 1976 investigation of a missing dhow and, in 1992, the investigation of the loss at sea of a fisherman off Greater Hanish.

337. In addition, Yemen asserts that for many years the local fishermen have used their own customary law system of arbitration of local disputes under the authority of an aq'il - "a person known for wisdom and intelligence." There is a senior "Aq'il of the Sea" the most noted of whom is said to have "resided part of the year on the Yemeni mainland and part of the year at his settlement ('Izbat al-Sayyid' Ali) on Greater Hanish." The final authority above village aq'ils or the Aq'il of the Sea is the "Aq'il of the Fishermen," who is a dignitary officially recognized by the Government of Yemen.

338. The aq'ils apply what is asserted by Yemen to be a "well-established Yemeni body of customary law, known as the urf ", to resolve the fishermen's disputes. There is evidence before the Tribunal that the judgments or decisions of aq'ils are binding.(23) Indeed, in the man overboard case just referred to, the evidence before the Tribunal is that "[t]he owner and crew members both informed the local official, who is known as the Aq'il Sheikh of the Fishermen, and the Department was notified by the Aq'il."

339. The existence of this customary law system of arbitration of small disputes does not appear to be contested by Eritrea. There is evidence that the urf and the aq'il system appear to be applicable to Yemenis and non-Yemenis within Yemeni territory, and to be regularly applied to problems occurring on the Islands.

340. In the Tribunal's understanding, the rules applied in the aq'il system do not find their origin in Yemeni law, but are elements of private justice derived from and applicable to the conduct of the trade of fishing. They are a lex pescatoria maintained on a regional basis by those participating in fishing. This reflects the reality also that the principal market for fish is in Hodeidah, on the Yemeni side, and that the fishing activities in the area of the Islands have long been conducted indiscriminately by fishermen on each side of the Red Sea on a regional basis. The fact that this system is recognized or supported by Yemen does not alter its essentially private character.

Construction or Maintenance of Lighthouses

341. The question of lighthouses has already been discussed above in Chapter VI. The present section examines this material only for the purposes of the present chapter on effectivités. The lighthouses as Abu Ali and Jabal al-Tayr were administered by the lighthouse management company, Savon & Ries. This company maintained its operation in Asmara until 1976, when it moved its office to Somalia because of prosecution of its staff by the Ethiopian Government for allegedly subversive operations (see para. 335, above). There is however no legal basis for concluding that the location within a state of the office of a private firm, operating under a management agreement for the maintenance of lighthouse facilities on islands, constitutes an intentional display of power and authority by that state.

342. As to Yemen, starting in 1987 a programme of installation of new lighthouses in the Islands was undertaken, beginning with Centre Peak in 1987 and 1988 , and Jabal Zuqar in 1989.

343. Following the 1989 London Conference on Red Sea Lights, Yemen installed new solar lighthouses on Jabal al-Tayr and Quoin (Abu Ali islands). In 1991, a new lighthouse was constructed on Low Island. Finally, a lighthouse was erected on Greater Hanish in 1991.

344. Yemeni Governmental authorities communicated the construction and identification of each of these lighthouses to the public by means of public notices or Notices to Mariners, as described more fully in paragraph 282 above.

345. The legal effect to be given to the construction and maintenance of lighthouses in this particular case has been dealt with in Chapter VI, above.

Granting of Oil Concessions

346. Because of the significant attention devoted to the legal implications of petroleum agreements and activities in supplemental written and oral pleadings, this topic is treated separately in Chapter IX.

Limited Life on the Islands

347. There is also evidence that some of the Yemeni fishermen have maintained "dwellings" on Greater Hanish, Lesser Hanish, and Zuqar, and have traditionally maintained those structures for a long time; or have "settled" on Greater Hanish for the summer , or on Addar Ail Islets or Lesser Hanish for the summer.

348. Eritrea has advanced some evidence that Eritrean fishermen would stay for brief periods on the Islands during the fishing season, but the assertions of "settlements" do not appear to be as prominent in the evidentiary record as those made on behalf of Yemen. There is evidence by one fisherman however that "the longest that I know of anyone staying on the islands is 7 to 8 months."

349. In the pleadings Yemen states that "some Yemeni fishing families have for generations maintained a permanent presence in the Hanish Group", and refers to "fishing families resident in the Hanish Group" in the same context as its discussion of "temporary dwellings" and other temporary residence by fishermen. No specific evidence has been produced about families living on the Islands.

350. One Yemeni witness statement records that naval landing parties "would meet many Yemeni fishermen . . . who were settled on some of these islands, salting and drying fish, and staying there for several months."

351. During the fishing seasons the fishermen from each side could be expected to spend days and nights on end fishing in and around the Islands, since returning to port - whether in Ethiopia/Eritrea or in Yemen - would cost a full day's sailing even if the winds were right. Eritrean evidence is that the Yemeni fishermen "would stay around the islands for only three or four days and then go home." Another old Eritrean fisherman recounts that "[w]e would go to the islands twice a year for three months at a time. Some of us preferred to sleep on the islands, and others would sleep on the boats. Since the islands were not inhabited, no one told us we could not sleep there."

352. A Yemeni witness declared in his statement that "[a]t Greater Hanish I would settle at the al-Shura anchorage . . . . There were trees there under which we would seek the shade. We would not have to make dwellings." The statement continues to describe the anchorages on Greater Hanish, saying that "[n]ear the Jafir anchorage is the dwelling of Capt. Ibrahim Salim and his crew . . . . At the other end of the island many others have settled, such as the anchorage where I am at al-Shura, then the al-Habal dwelling, and beyond is the Ibn 'Alwan anchorage. In the summer many people settle at the Ibn 'Alwan anchorage. From al-Qataba alone there are over 40 huris [small boats]."

353. The first conclusion must be that settled life on the Islands does not exist, but that episodic or seasonal habitation occurs, and that it appears to have taken place for many years. Eritrea asserts that its fishermen have been predominant, and Yemen asserts the reverse. There is no evident manner in which the Tribunal can, on the basis of the sparse and conflicting evidence before it, decide the matter one way or another. The likelihood is not that one nationality prevailed and the other was absent, but that both were present on the Islands in varying numbers and at various times - and that any precise calculation of relative use would, over time, reveal what may be perceived as a genuinely common use of the waters and their resources.

354. The second conclusion appears to be that the manner of living on the Islands is equally indiscriminate: some fishermen stay on their boats; others sleep on the beach; some construct small shelters; other use larger shelters; some consider their structures "settlements." The one thing that is clear from the record is that there is no significant and permanent dwelling structure, or in fact any significant and permanent structure of any other kind, that has been built and that has been used to live in.

355. The third conclusion is that it is not clear from the evidence, in spite of occasional references to "families" staying on the Islands, whether any family life is in fact present on the Islands. Inasmuch as the use of the islands is necessarily seasonal, this would seem to be a priori inconsistent with family life in the sense of family units migrating to a location where normal community activities continue, as for example with nomadic herdsmen.

356. The final conclusion must be that life on the Islands, such as it is, is limited to the seasonal and temporary shelter for fishermen. The evidence shows that many of them, of both Eritrean and Yemen nationality, appear to stay on the islands during the fishing season and in order to dry and salt their catch, but that residence, although seasonal and regular, is also temporary and impermanent.

357. For the time being however it would appear that there is little question but that this type of activity on the part of nationals of both Yemen and of Eritrea (and Ethiopia) is activity which, in the words of the Court in the Anglo-Norwegian Fisheries case of 1951, represents a "consideration not to be overlooked, the scope of which extends beyond purely geographical factors: that of certain economic interests peculiar to a region, the reality and importance of which are clearly evidenced by a long usage."(24)

General Activities

358. Finally, evidence of more general activities has been presented to the Tribunal by the Parties. This evidence includes assertions of conduct relating to overflight and miscellaneous activities.

Overflight

359. The act of overflying a substantially deserted group of islands is not one that would appear to constitute with any cogency an intentional display of power and authority over them. However it may be noted that in its Attachment 2 to the response given by Yemen to Question 18 ("Chronology of Selected Yemeni Acts Manifesting Sovereignty . . .") a number of overflights are recorded, commencing in April 1982 and proceeding through 1988. Doubtless they were important incidents of watching the unfolding of the Eritrean liberation struggle during that decade, but in any event the Tribunal can accord no substantial weight to these activities.

Miscellaneous Activities

360. Yemen has listed a broad variety of actions and acts in a sixteen-page attachment to its response to the Tribunal's Question 18. A variety of actions of many different categories have been advanced as supporting the respective contentions for consolidation of title over the Islands. The Tribunal has noted the most legally significant acts and positions in its earlier analysis.

361. Considerable emphasis, however, has been placed by Eritrea on an inspection tour conducted by President Mengistu and his staff in 1988. A videocassette of this tour around the Islands was also provided to the Tribunal. The Tribunal is unable to draw any conclusions from this episode, however, as the presidential party passed the Islands at speed and at some distance offshore, and did not stop or go ashore. No question of an intentional display of power and authority over a territory would seem to be raised by such a passage.

Notes - Chapter VII

19. Eritrea has submitted two translations of this document, one of which refers to "jurisdiction" and the other to "sovereignty".

20. Map 3 (dated November 1993) shows Area 10 ("Bera'isole") and Area 11 ("Beilul"), but Area 12 is actually "Assab-Dumeira."

21. The samples of fishing and boat licenses supplied by Yemen are not helpful; when they specify fishing areas, they only state "Red Sea."

22. In one example, it appears that the officer of the watch has helpfully added estimated radar ranges of distance, e.g.: "Ø Jabal at Tair Isl. 045° 6.0 by radar," and "Ø Haycock Isl. 106° 15 by radar," showing that the vessel (H.I.M.S. PC-12) was far offshore on both occasions.

23. According to a witness statement submitted by Yemen, ". . . any disputant who seeks to avoid an unfavorable decision of the Council may find himself subject to action by the State, including, under certain circumstances, prison."

24. Fisheries Case (U.K. v. Nor.) 1951 I.C.J. 116 (Dec. 18) at 133.
