Article 31 Vienna Convention on Consular Relations
Inviolability of the consular premises
1.Consular premises shall be inviolable to the extent provided in this article.
2.The authorities of the receiving State shall not enter that part of the consular premises which is used exclusively for the purpose of the work of the consular post except with the consent of the head of the consular post or of his designee or of the head of the diplomatic mission of the sending State. The consent of the head of the consular post may, however, be assumed in case of fire or other disaster
requiring prompt protective action.
3.Subject to the provisions of paragraph 2 of this article, the receiving State is under a special duty to take all appropriate steps to protect the consular premises against any intrusion or damage and to prevent any disturbance of the peace of the consular post or impairment of its dignity.
4.The consular premises, their furnishings, the property of the consular post and its means of transport shall be immune from any form of requisition for purposes of national defence or public utility.
If expropriation is necessary for such purposes, all possible steps shall be taken to avoid impeding the performance of consular functions, and prompt, adequate and effective compensation shall be paid to the sending State.
