Article 23 Other medical ships and craft

Medical ships and craft other than those referred to in Article 22 of this Protocol and Article 38 of the Second Convention shall, whether at sea or in other waters, be respected and protected in the same way as mobile medical units under the Conventions and this Protocol. Since this protection can only be effective if they can be identified and recognized as medical ships or craft, such vessels should be marked with the distinctive emblem and as far as possible comply with the second paragraph of Article 43 of the Second Convention.

The ships and craft referred to in paragraph 1 shall remain subject to the laws of war. Any warship on the surface able immediately to enforce its command may order them to stop, order them off, or make them take a certain course, and they shall obey every such command. Such ships and craft may not in any other way be diverted from their medical mission so long as they are needed for the wounded, sick and shipwrecked on board.

The protection provided in paragraph 1 shall cease only under the conditions set out in Articles 34 and 35 of the Second Convention. A clear refusal to obey a command given in accordance with paragraph 2 shall be an act harmful to the enemy under Article 34 of the Second Convention.

A Party to the conflict may notify any adverse Party as far in advance of sailing as possible of the name, description, expected time of sailing, course and estimated speed of the medical ship or craft, particularly in the case of ships of over 2,000 gross tons, and may provide any other information which would facilitate identification and recognition. The adverse Party shall acknowledge receipt of such information.

The provisions of Article 37 of the Second Convention shall apply to medical and religious personnel in such ships and craft.

The provisions of the Second Convention shall apply to the wounded, sick and shipwrecked belonging to the categories referred to in Article 13 of the Second Convention and in Article 44 of this Protocol who may be on board such medical ships and craft. Wounded, sick and shipwrecked civilians who do not belong to any of the categories mentioned in Article 13 of the Second Convention shall not be subject, at sea, either to surrender to any Party which is not their own, or to removal from such ships or craft; if they find themselves in the power of a Party to the conflict other than their own, they shall be covered by the Fourth Convention and by this Protocol.
