Phase I: Territorial Sovereignty and Scope of Dispute

CHAPTER VI – Red Sea Lighthouses

200. The Red Sea lights bear on this arbitration in three main ways. First, each of the parties has at various moments suggested that its establishment or maintenance of lighthouses on the various islands constitute acts of sovereignty. Second, the diplomatic correspondence relating to the lighthouses might throw some light on the underlying claims to the islands where they are located, not least because the lighthouse islands were necessarily named. So much of the other material relates to islands without specification. Third, the relationship between the several lighthouse conventions and the provisions of Article 16 of the Treaty of Lausanne might have some legal significance.

201. From the late 19th century the Red Sea lights have had an historical importance in this region, although this is now somewhat reduced with the advent of radar. But radar may not be available to many of those fishing in the Zuqar-Hanish islands. The Ottoman authorities, and later the various coastal states, along with the major shipping users, have all played a role in the story of the Red Sea lights. In 1930, a proposed treaty regime for the lights was drawn up, but never came into force. From 1962 until 1989, a treaty regime did indeed govern the lights.

202. In 1881, the Ottoman Empire granted a forty-year concession to the Société des Phares de l'Empire Ottoman, owned by Messieurs Michel and Collas, to build a series of lighthouses in the Red Sea and the Persian Gulf. Almost endless disputes were to arise regarding the concession for the Red Sea lighthouses.

203. The British Government had proposed to the Sublime Porte that four lights should be erected at Jabal al-Tayr, Abu Ail, Jabal Zubayr and at Mocha, to assist navigation. Anxious at the difficulties encountered with the concessionaires, it began in 1891 to revive an earlier idea to explore the possibility of a western navigation route through the Red Sea. As the envisaged route was to be "abreast of the Italian possessions at Assab", Italy was asked to facilitate the technical mission and to allow supplies to be taken on at Assab - a request to which Italy readily agreed.

204. Once a western route was recommended by the Board of Trade, the British Government had to concern itself with questions of title. The so-called "Western Hanish" route would have entailed lights on North East Quoin (or at Rakmat), South West Rocks, one of the Haycock islets and Harbi islet. In 1891 the Board of Trade, relying on the Hertslet Memorandum of 1880, suggested that North East Quoin and Harbi were within Egyptian jurisdiction and South West Rocks and the Haycocks within Ottoman jurisdiction - with the Sublime Porte claiming sovereignty to all four islands. The Marquis of Salisbury, in writing to the British Ambassador to Rome in January 1892, stated "The islands and rocks recommended by the Board of Trade . . ., with the exception of South-west Rocks, seems [sic] to be in effect within the jurisdiction of Italy. That over the South-west Rocks would appear to be doubtful." From 1881 to 1892 there was an extended international correspondence on this subject.

205. A Note of 3 February 1892 was addressed to the Italian government to seek clarification. The Note included the statement that "according to Article 3 of the Treaty between Italy and Sultan Ahfari of Aussa of the 9th December 1888", the jurisdiction over the new sites, "with the exception perhaps of South-West Rocks, appears to belong to Italy." Italy was asked whether it claimed jurisdiction over these sites, and if so whether it would itself be prepared to erect lights there, or alternatively if it would be willing for Great Britain to do so.

206. The Italian Government replied in June of that year that "the King's Government consider these points as a maritime appendage of the territory over which they exercise their sovereignty" but urged the British Government to erect and maintain the lighthouses and to fix the method of reimbursement.

207. In the event, the western route was not proceeded with and the Ottomans arranged for the building of four lighthouses at Mocha on the Arabian coast, and on Jabal al-Tayr, on Abu Ali and in the Zubayr group (on Centre Peak). This was maintained by the French concessionaires for the Ottomans until 1915. Great Britain occupied the three lighthouse islands in 1915.

208. When the Ottoman Empire was required to renounce its possessions, sovereignty over the lighthouse islands fell, under Article 16 of the Treaty of Lausanne, "to be settled by the parties concerned". The light at Mocha was recognised by Great Britain as being within the territory succeeded to by the Imam. Great Britain had on occasion contemplated trying to acquire sovereignty over the islands it occupied but on balance thought they did not have enough strategic value. It is significant that Great Britain did not regard itself as precluded from attempting to acquire sovereignty by the terms of Article 16 of the Treaty of Lausanne. It was not until 1927 that Great Britain formally stated (to France) that it had definitely renounced this idea. And in certain quarters the idea of annexing Hanish and Zuqar, as well as Jabal al-Tayr and Abu Ali, was not totally dead even in 1944.

209. It is also striking that, throughout the series of enquiries that Great Britain was to make after 1923 to Italy about the status of certain other islands, it never once put to Italy that a claim would be contrary to the terms of Article 16 of the Treaty of Lausanne. Rather, Great Britain was content to satisfy itself that Italy's position was consistent with the bilateral understandings of the Rome Conversations of 1927.

210. Notwithstanding this, the Tribunal has already indicated that in its view the history, text and purpose of Article 16 argues against the unilateral acquisition of title over the islands whose status was left undetermined in 1923. Nor is it necessary to consider whether Italy was seeking to establish title contrary to the agreement in hand and entered into in the Treaty of Lausanne, because Italy's posture was in fact much more cautious.

211. In 1927 Great Britain negotiated an agreement with France for the maintenance of all four lighthouses by the French company and approached the main users of the route - Germany, the Netherlands, Japan and Italy - to regulate the matter by a convention. Italy, expressing the wish that it had been consulted earlier, made two points. First, Mocha was claimed by the Imam and he should be a party. Second, Italy wished to know whether sovereignty of the islands was to be attributed to the neighbourhood coast or whether the point would be reserved. No Italian claim to any of the islands was presented. The British Government conceded that Mocha was under the rule of the Imam and affirmed that the status of the islands was to be reserved. These reassurances led to the conclusion of the Convention concerning the Maintenance of Certain Lights of 1930.

212. Although this Convention did not enter into force, and thus cannot be said to bind the parties as a treaty, it is useful evidence of their thinking at that date. The preamble and the annex refer to the renunciation by Turkey of both the islands and of Mocha, the occupation of the islands by Great Britain, and the provision in Article 16 of the Treaty of Lausanne that "the future of these islands, and of that territory [is] a matter for settlement by the Parties concerned." The annex continued: "(e) . . . no agreement on this subject has been come to among the parties concerned and it is desirable in the interests of shipping to ensure that the lighthouses on the said islands shall be maintained". It then proceeded to determine that a lighthouse company should take possession of and manage the lighthouses on Abu Ali, Zubayr and Jabal al-Tayr. Italy was prepared to put its signature to this and to Article 13, which clearly affirmed the continued operation of Article 16 of the Treaty of Lausanne:

Art. 13. In the event of the arrangement contemplated in article 16 of the Treaty of Lausanne being concluded between the parties concerned, the High Contracting Parties will meet in conference in order to decide whether it is desirable to terminate the present Convention, or to modify its terms with a view to making it conform to the aforesaid arrangement.

213. Although the 1930 Convention was ratified by Italy and the Netherlands, it did not come into force, because the French Government was locked in disagreement with the British Government as to whether the lighthouse company, Michel et Collas, should be paid on the basis of gold. France refused to ratify.

214. In the meantime, in the very same year, Italy was preparing to erect a lighthouse on South West Haycock. The Haycocks had not been specifically mentioned in the 1927 Rome Conversations and the British were anxious to establish that Article 5 thereof should nonetheless apply, the more so as "the erection of a lighthouse . . . may be regarded as implying some definite claim to sovereignty." Great Britain was concerned as to whether indeed South West Haycock did fall within the Rome Conversations - there were internal divisions on the question of title - and it noted that the islet was only 20 miles from the "Italian" coast. It was decided to seek assurances. These were sought in an aide-memoire of 18 February 1930, in which Italy was reminded of the earlier exchanges in 1927. In that document Great Britain referred to South West Haycock as being "in the Hanish group of Islands".

215. In its Pro-Memoria of 11 April 1930, Italy observed that the lighthouse was being built for navigational reasons. It asserted that South West Haycock was not part of the Hanish islands, but rather belonged to the Mohabbakah archipelago over which it alleged that the Ottomans had never claimed sovereignty.(17) Italy therefore made "a special reserve regarding Italian sovereignty over this island" and then consented to "the question being considered on the same lines as that of the sovereignty of all the islands of the Hanish group, in accordance with the spirit of the conversations of Rome of 1927."

216. The Pro-Memoria can only be read as a claim to sovereignty over South West Haycock by Italy (while at the same time agreeing that the erection of the lighthouse was to be treated as a commercial rather than a sovereign act) and a failure to advance a comparable claim to title over the Hanish group. The internal evidence shows that this was an assessment that Great Britain was at the time inclined to accept, and with which it was satisfied; although in other documents Great Britain treats South West Haycock as part of the Hanish group, and as having been Ottoman. In the event, all fell to be treated as provided by Article 16 of the Treaty of Lausanne, which was reinforced by the understandings reached in the Rome Conversations.

217. The South West Haycock lighthouse was extinguished in 1940. It was abandoned after 1945. When the 1930 Convention failed to come into effect the British authorities were left with the sole financial burden of the existing lights. It decided to abandon the Centre Peak light (in the Zubayr group) from September 1932 and Italy (which had been notified, along with France) reactivated the Centre Peak light in 1933. The decision was taken in Italy to inform the "interested powers" that this was being done for reasons of navigational necessity, and that the Imam "who lays claim to rights over the islands" should be "informed of the provisional nature of the occupation and the usefulness to himself in having the lighthouse reactivated." It was apparently originally intended to ask for contributions, but in the event this was not done.

218. The British authorities were notified by Note Verbale on October 4, 1933 of the anxieties of the Captain of the Port at Massawa as to safety on the Massawa-Hodeidah route, in the absence of the Centre Peak light, and of Italy's decision to take over the lighthouse. The Note Verbale expressly stated:

. . . the Royal Ministry for Foreign Affairs need hardly add that the presence of an Italian staff on the Island of Zebair (Centre Peak), which will ensure the operation of the light, implies no modification of the international judicial status of the island itself, which, together with the islands of Abu Ail and Gebel Taiz [sic], was considered by the Italian and British governments in 1928 during the negotiations for the Red Sea Lights Convention, when the conclusion was reached that the question of sovereignty of those islands should remain in suspense.

219. Thus in the northern islands, too, Italy had established a navigational interest but affirmed that it had no implications for sovereignty. The British decided this was a sufficient comfort not to have to pursue this matter further with the Italians.

220. The situation remained essentially unchanged by the 1938 agreement. Article 4(2) of Annex 3 again affirmed that neither Great Britain nor Italy would establish sovereignty over the renounced islands, following Article 16 of the Treaty of Lausanne, and that no objections would be raised to lighthouse personnel.

221. By the outbreak of the Second World War it may be said that the maintenance of the lights is seen as a non-sovereign act and there is agreement that the underlying title to the islands concerned was left in abeyance - though Italy had asserted title (even if choosing not to press it) to South West Haycock. But this turned upon a perception of South West Haycock as being part of the Mohabbakahs, rather than upon any suggestion that the erection of a lighthouse thereon itself had a role in establishing sovereignty. In the course of the Second World War, the South West Haycock and the Centre Peak lights were extinguished.

222. In June 1948 the British Military Authority (BMA) in Eritrea sought legal advice as to whether it was liable under any international conventions for the re-establishment of various lights previously operated by the Government of Italy. These included those at South West Haycock and at Centre Peak. The advice (which eventually came from the Ministry of Transport) was that there was no obligation under any convention.

223. The decision by the BMA that it had no responsibility for the lights at South West Haycock and Centre Peak was not because it thought those islands were not Italian. No particular attention seems to have been given to that aspect. Rather, it was decided that as long as the Abu Ali light was maintained there was no real danger to shipping. Further, the Admiralty advised that a state was under no obligation to light its coasts. Thus even if South West Haycock and Centre Peak had been Italian (and neither was addressed in the 1948 correspondence nor is there any evidence that Zubayr was ever regarded by the British as Italian), no obligation was passed to the BMA as the occupying power.

224. After the Second World War, the British did continue to take responsibility for the lighthouses at Abu Ali and Jabal al-Tayr, and from 1945 received financial contribution from the Netherlands. These arrangements were in 1962 brought within an agreement made between Denmark, Federal Republic of Germany, Italy, the Netherlands, Norway, Sweden, the United Kingdom and the United States, and formally accepted also by Pakistan, the Soviet Union and the United Arab Republic. Yemen was not a party. Nor was Ethiopia. The criterion for invitation was clearly that of navigational importance and not of title to the coast or islands. The opening recitals to the 1962 agreement rehearse the history of the Abu Ail and Jabal al-Tayr lights, recall the abortive 1930 Convention, refer to Article 16 of the Treaty of Lausanne, and add: "No agreement on the subject of the future of the above-mentioned islands has been come to among the Parties concerned."

225. Further, Article 8 was to make crystal clear that nothing in the text following was to be regarded either as a settlement of the future of the islands referred to in Article 16 of the Treaty of Lausanne, "or as prejudicing the conclusion of any such settlement." This Article reproduces the provisions of Article 15A of the 1930 Lighthouses Convention. The United Kingdom was affirmed as the "Managing Government" for these two lights and was entitled to appoint an agent for this purpose (Article 2). Article 6 provided for discontinuance of this role upon notice to the other parties, and indicated the procedures to be followed in that eventuality.

226. As in 1930, the managerial role of the United Kingdom had nothing to do with the issue of title to the islands; nor did management even place the United Kingdom in a favourable position for when the title issue came to be resolved. This clearly followed the pattern of the Rome Understandings (as they bear on the management of lights) and of the abortive 1930 Convention - even though the 1962 Convention concerned two lights only.

227. The United Kingdom managed the lighthouses at Jabal al-Tayr and Abu Ali from Aden, but realised that arrangements would have to be made when the British would leave Aden upon the independence of the People's Democratic Republic of Yemen in 1967. The Savon and Ries Company was accordingly appointed agent under Article 2 of the 1962 agreement, for management duties. It so happened that Savon and Ries were operating out of Massawa, and the staff engaged in lighthouse functions at the Board's request came increasingly from Ethiopia, but in the view of the Tribunal this was simply a matter of practical convenience. The various Ethiopian authorizations for inspection and repair visits to the islands and the control exercised over radio transmissions were immaterial as to sovereignty. Everything remained as it had been so far as title to the islands was concerned - that is to say, Article 8 of the 1962 Convention continued to govern.

228. In 1971 the British Government decided to replace the lights by automatic lights, dispensing with the services of lighthouse-keepers. The United Kingdom notified Yemen of this intention, assured that Government that "the action of the Board of Trade in accordance with [the 1962 convention] does not infringe upon rights of sovereignty" and asked whether Yemen had any objection. The fact that the communication was addressed to Yemen, a non-signatory of the 1962 Convention, would seem to indicate that, while the islands remained unattributed in accordance with the terms of the 1962 Treaty, Yemen was regarded by the United Kingdom as a "party concerned" within the terms of Article 16 of the Treaty of Lausanne and as having claims to Abu Ali and Jabal al-Tayr that should not be prejudiced. It may also be noted that by this time Italy had lost its possessions on the Red Sea coast and was not, therefore, any longer a "party concerned" within the meaning of Article 16 of the Treaty of Lausanne.(18)

229. Although at an earlier era the legal advice within the British Government was that Abu Ali and Jabal al-Tayr (as well as Centre Peak) were islands that were res nullius and various candidates had been suggested at different moments of time as "parties concerned", it would seem that by the early 1970s Yemen was regarded as the leading "party concerned" for purposes of Article 16 of the Treaty of Lausanne, at least so far as Abu Ali and Jabal al-Tayr were concerned.

230. In 1975 the management of these two lights was transferred from Savon and Ries' offices in Ethiopia to its offices in Djibouti. Five years later, the agency for management was passed by the British authorities to a new company it had formed, the Red Sea Lights Company.

231. In 1987 Yemen relit the lighthouse on Centre Peak, issued pertinent Notices to Mariners and, in 1988, upgraded it. This appears to have occasioned no protest by Ethiopia, which could not have assumed that such acts were rendered without significance by virtue of Article 16 of the Treaty of Lausanne (to which Yemen was not a party), or by the various bilateral Italian-UK agreements, or by the 1962 Lighthouse Convention - none of which were opposable to Yemen.

232. On June 20, 1989, Yemen contacted the United Kingdom regarding "the matter of the Lighthouses installed on Abu Ali (Ail) and Jabal al Tair Islands which is to be discussed on Tuesday 20 June 1989." Yemen formally stated that:

1. The two Islands mentioned above lie within the exclusive economic zone of the Yemen Arab Republic.

2. In the light of this fact the Yemen Arab Republic is willing to take the responsibility of managing and operating the said two lighthouses for the benefit of National and International Navigation. As you may be aware, the Ports and Marine Affairs Corporation in the Yemen Arab Republic is already running and operating several lighthouses some of which lie within the area of these two Islands.

233. Unless positive action was taken to extend the 1962 Convention, it would expire in March 1990. In 1988 and 1989 it became clear that many parties had denounced the 1962 Treaty or indicated their intention to do so. The United Kingdom, the managing authority of the lights, was among these. Egypt offered to take over that role, but it was clear that there were not sufficient votes for extending the Convention beyond 1990.

234. A meeting of the parties was held in London in June 1989. Having established its credentials and interest, Yemen was invited as an observer to the 1989 Conference on the future of the two northern lights, notwithstanding the fact that (like Ethiopia) it had not been a party to the 1962 agreement. The Report to the Government of Yemen of the Yemeni technicians attending the 1989 meeting refers to the fact that the British had confirmed the installation and operation by Yemen of new lighthouses on Jabal Zubayr and Jabal Zuqar. Manifested interest and professional competence appear to be the motivating factors for Yemen's presence. Ethiopia was not invited to attend and had not requested this.

235. Yemen supported the Egyptian proposal that Yemen would manage the lighthouses on Jabal al-Tayr and Abu Ali and did so without reserve as to title. The minutes show that they also indicated their willingness to operate lights on the two islands at their own expense with almost immediate effect should the agreement lapse. The minutes contain no reference by Yemen to the islands being in its Exclusive Economic Zone - though that point had been included in the pre-meeting exchanges with the United Kingdom.

236. The reference to Yemen's Exclusive Economic Zone rather than to title to the islands themselves does not appear to have been casual. It is mentioned twice again in the internal report sent after the 1989 conference from the Yemeni Director-General of the Ports and Maritime Affairs to the Government of Yemen. Yemen's offer - which was accepted - was in language other than claim of a right of sovereign title. Yemen did not say that it had title to Abu Ali or Jabal al-Tayr, nor to the nearby islands, and thus it would be for it alone to provide any lights. The 1961 agreement had no chance of survival and Egypt's offer to become managing authority could not provide the answer. The international treaty regime for the Red Sea lights was coming to an end.

237. The erection and maintenance of lights, outside of any treaty arrangements and for the indefinite future, had certain implications. The acceptance of Yemen's offer did not constitute recognition of Yemen sovereignty over islands. But it did accept the reality that Yemen was best placed, and was willing, to take on the role of providing and managing lights in that part of the Red Sea; and that when the time came finally to determine the status of those islands Yemen would certainly be a "party concerned". (Yemen, of course, was not bound by Article 8 of the 1962 Convention and indeed appears not to have known at the time of the arrangements made under it.)

238. Eritrea has contended that there was no need for Ethiopia to have protested the relighting by Yemen of lights on Abu Ali and Jabal al-Tayr, as its "activities were merely a continuation of the historic activities of Great Britain on Jabal A'Tair and Abu Ali." But Yemen was not in the same legal relationship with Ethiopia over the matter of lights as had been Great Britain and, if such was the reasoning for a failure to reserve claimed Ethiopian sovereignty, it was misplaced.

17. The Tribunal notes, however, that prior to Italian occupation, the islands off the African coast were administered by the Khedive of Egypt on behalf of the Ottoman Empire.

18. Nor has Italy or, for that matter, any state asserted that it considers itself to be "a party concerned" for this purpose. The Tribunal therefore concludes that, with respect to the islands in dispute, the only present-day "parties concerned" are the Parties to this arbitration.
