6. The sending State, its diplomatic missions and its consular posts may designate consular couriers ad hoc. In such cases the provisions of paragraph 5 of this article shall also apply except that the immunities therein mentioned shall cease to apply when such a courier has delivered to the consignee the consular bag in his charge. 7. A consular bag may be entrusted to the captain of a ship or of a commercial aircraft scheduled to land at an authorized port of entry. He shall be provided with an official document indicating the number of packages constituting the bag, but he shall not be considered to be a consular courier. By arrangement with the appropriate local authorities, the consular post may send one of its members to take possession of the bag directly and freely from the captain of the ship or of the aircraft. Article 36 Communication and contact with nationals of the sending State 1. With a view to facilitating the exercise of consular functions relating to nationals of the sending State: (a) consular officers shall be free to communicate with nationals of the sending State and to have access to them. Nationals of the sending State shall have the same freedom with respect to communication with and access to consular officers of the sending State; (b) if he so requests, the competent authorities of the receiving State shall, without delay, inform the consular post of the sending State if, within its consular district, a national of that State is arrested or committed to prison or to custody pending trial or is detained in any other manner. Any communication addressed to the consular post by the person arrested, in prison, custody or detention shall be forwarded by the said authorities without delay. The said authorities shall inform the person concerned without delay of his rights under this subparagraph; (c) consular officers shall have the right to visit a national of the sending State who is in prison, custody or detention, to converse and correspond with him and to arrange for his legal representation. They shall also have the right to visit any national of the sending State who is in prison, custody or detention in their district in pursuance of a judgement. Nevertheless, consular officers shall refrain from taking action on behalf of a national who is in prison, custody or detention if he expressly opposes such action. 2. The rights referred to in paragraph 1 of this article shall be exercised in conformity with the laws and regulations of the receiving State, subject to the proviso, however, that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under this article are intended. 15
