Members of the PLO Observer Mission are invited to the United Nations, in accordance with resolution 3237 (XXIX). As such, they are covered by Sections 11, 12 and 13 of the Headquarters Convention of 26 June 1947. Therefore, the host country has a contractual obligation to allow PLO personnel to enter the United States and remain in the United States to perform their official duties at United Nations Headquarters. The Secretary-General undertakes to provide passports to duly authorized employees of New York City, New York State or any of its agencies or subdivisions, to enable them to inspect, repair, repair, rebuild and install utilities, pipes, pipes and sewers within the head office. According to the report of the Secretary-General of 10 February 1988 [A/42/915] notes that the United States of America has not been able and unwilling to formally enter the dispute settlement procedure referred to in section 21 of the Headquarters Agreement, and that the United States continues to assess the situation, 50. One might, of course, ask whether, under United States domestic law, the decisions taken by the Attorney General on 11 and 21 March 1988 had the effect of applying the Anti-Terrorism Act or whether the Law can be considered effective only if or if, following the ongoing judicial proceedings, the PLO`s mission is effectively closed. However, this is not decisive for Section 21 of the Headquarters Agreement, which deals with disputes “relating to the interpretation or application” of the Agreement and not to the application of measures taken in local United States law. The Court therefore sees no reason not to establish that there is a dispute between the United Nations and the United States concerning the `interpretation or application` of the Headquarters Agreement. (b) At the request of the Secretary-General, the competent United States authorities shall provide a sufficient number of police officers to maintain law and order in the district and to expel requested persons under the supervision of the United Nations. Upon request, the United Nations shall make arrangements with the competent United States authorities to reimburse them for the reasonable costs of such services. (b) The United Nations shall conclude agreements on the operation of the services referred to in this Section with the International Telecommunication Union, the competent agencies of the Government of the United States and the competent agencies of other governments concerned for all frequencies and similar matters. .
