In 1959 Cambodian government has filed the case to International Court of Justice about the illegal control of Thailand government over Preah Vihear. After that, ICJ has called both conflicting parties to the court to show their evidence of claiming over Preah Vihear temple.
Even though, Cambodia and Thailand are the parties of 1904 and 1907 treaty, but they have different perspective toward the Preah Vihear case. For Cambodia perspective, they argued that Preah Vihear temple was under the sovereignty of Cambodia that has decided by the Cambodian and Thailand Mixed Delimitation Commission (Katelin, 2009). On February 13, 1904 Thailand and French government has signed a treaty called Franco-Siamese Mixed Commission that talk about the location of Preah Vihear. During that time, Cambodia government under the protectoral of French colonial. Moreover, in 1904 treaty has drawn the boundary line of Dangrek mountain that include Preah Vihear temple (Saikia, 2012). In 1907 there was a latest round meeting between French and Thailand that focus about the map that French government has drawn and send it to Thai government in 1907 to specified Preah Vihear location. Based on the Annex I map that has drawn by French expert, Cambodia side stated that the location of Preah Vhiear temple is fully under Cambodia territory. In contrast, Thailand government reject all the statement that claim by Cambodia government, especially about the Annex I map that claim by representative of Cambodia.
They argued that the Annex I map has not been accepted by the First Franco-Siamese Mixed Commission in 1904 (Sophanny, 2014). Annex I map that talk about the location of Preah Vihear has never officially accepted by the Thailand government. Because the maps received from French official were only seen by minor officials who had no expertise in cartography (Thailand Forum, n.d.). Therefore, the representative of Thailand government also claims that the Annex I map that was include in French-Siamese treaty in 1904 is no jurisdiction over the Thailand government to perform their obligation to accept the temple is under Cambodia territorial control.
Moreover, the map has an error about the deviation from the watershed (Bora, 2009). Even Thailand is the member of United Nations but Thailand did not fully accept the compulsory jurisdiction of ICJ. Last but not least, both parties have their own stand in this case and the conflict has solve by international court.
