What Indicates This Sovereignty ?

(A) The three Islands hoist the flags of Sharjah and Ras al-Khaimah. The laws Regulations and customs of the two Emirates are followed on the Islands, and the residents of the Island are citizens of the two Emirates.
(B) Representatives of the Rulers of the two Emirates are always present on the Islands.
(C) The Rulers of Sharjah and Ras al-Khaimah collect annual fees for the economic activities undertaken by the residents of the Islands, such as fishing, pearl diving and herding.
(D) The Islands of Abu Musa and Greater Tunb have public utilities that belong to the Emirate of Sharjah and Ras al-Khaimah. Lesser Tunb has no such utilities because of its size and the lack of fresh water resources. This Island was under the direct supervision of the representative of Ras al-Khaimah in Greater Tunb, who used to make periodic visits to the Island of Lesser Tunb.
(E) Since the turn of the century, Sharjah and Ras al-Khaimah have granted licenses for exploration and oil drilling in their Islands and their territorial waters. For example, the Ruler of Sharjah granted several companies licenses which authorized them to exploit iron oxide in Abu Musa in 1898, 1933, and 1935, the last having a 21-year term. Likewise, the Ruler of Sharjah granted oil concession in Abu Musa to Petroleum Co.Inc. in 1937 and to Buttes Co. in 1970.
With respect to the Islands of Greater Tunb and lesser Tunb, the Ruler of Ras al-Khaimah granted licenses for iron oxide exploitation in 1952, in addition to oil drilling licenses to two American companies in 1964.
Iran has made intermittent claims on the Islands, but these claims were not supported by any legal evidence. And were contradicted by subsequent conduct of the Iranian Government which offered, through the British Government, to purchase the two Islands from Ras al-Khaimah in 1929. However, the Ruler of Ras al-Khaimah rejected the offer and the British Government notified Iran of the rejection.
In October 1930, the Iranian Government submitted a proposal to the Ruler of Ras al-Khaimah in which it offered to lease the Island of Greater for a period of 50 years. Once again, the Iranian Government offered to purchase the Islands in 1971, but its offer was turned down.
This Iranian conduct warrants the application of the principle of international law, which stipulates that if a certain party by words or deeds, behaves in a manner that contradicts its claims, then it should cease raising those claims.
On more than one occasion, through official documents and correspondence dating back to the 19th Century, the British Government stated that it recognizes the right of Sarah and Ras al-Khaimah Awaits to recognizes the right of sharjah and Ras al-Khaimah to exercise sovereignty over the Islands. The British also opposed the Iranian claims, and warned Iran in September 1934 not to challenge the status of the Islands and threatened to resist any Iranian intervention on the Islands.
