Article Comparison - Geneva Convention on the High Seas
1. Except where acts of interference derive from powers conferred by treaty, a warship which encounters a foreign merchant ship on the high seas is not justified in boarding her unless there is reasonable ground for suspecting:
(a) That the ship is engaged in piracy; or
(b) That the ship is engaged in the slave trade; or
(c) That though flying a foreign flag or refusing to show its flag, the ship is, in reality, of the same nationality as the warship.
2. In the cases provided for in sub-paragraphs (a), (b) and (c) above, the warship may proceed to verify the ship's right to fly its flag. To this end, it may send a boat under the command of an officer to the suspected ship. If suspicion remains after the documents have been checked, it may proceed to a further examination on board the ship, which must be carried out with all possible consideration.
3. If the suspicions prove to be unfounded, and provided that the ship boarded has not committed any act justifying them, it shall be compensated for any loss or damage that may have been sustained.
