that right they freely determine their political status and freely pursue their economic, social and cultural development." Furthermore, resolution 2231 (XXI) itself recalls and demands implementation of Resolution 1514(XV) (guaranteeing Gibraltar's right to self-determination) and therefore it believes that the Spanish claim for its territorial integrity (which would not be affected by Gibraltar's decolonisation) cannot displace or extinguish the rights of the people of Gibraltar under resolution 1514(XV) or under the Charter. From this point of view, any additional right that Spain could claim by virtue of the "reversionary" clause contained in the Treaty of Utrecht is overruled and annulled under article 103 of the UN Charter: " In the event of a conflict between the obligations of the Members of the United Nations under the present Charter and their obligations under any other international agreement, their obligations under the present Charter shall prevail." Finally, it is argued that there is in fact no principle in International Law or UN doctrine that can displace the inalienable right to self-determination. In this regard, in 2008, the UN 4th Committee rejected the claim that a dispute over sovereignty affected self-determination, affirming it to be a basic human right. The Gibraltar Government has also argued that Gibraltar is a British territory and therefore by definition not an integral part of any other state, implying that Spain's territorial integrity cannot be affected by anything that occurs in Gibraltar: "Even if integration of a territory was demanded by an interested State it could not be had without ascertaining the freely expressed will of the people, the very sine qua non of all decolonisation." In a referendum held in Gibraltar in September 2002, Gibraltarian voters rejected even partial Spanish sovereignty. Gibraltarians seem to remain mistrustful of Spain despite improved relations. In 2022, following increased pressure from the Spanish government, Chief Minister Fabian Picardo said "Gibraltar will never be Spanish". Spanish position The traditional Spanish position is based on territorial integrity, as per UN Resolution 1514 (XV) (1960), which according to Spain, complements and constrains the right to self-determination: "Any attempt aimed at the partial or total disruption of the national unity and the territorial integrity of a country is incompatible with the purposes and principles of the Charter of the United Nations." During the 1960s, the UN General Assembly passed five resolutions on the issue (2231 (XXI), "Question of Gibraltar" and 2353 (XXII), "Question of Gibraltar").
