HL Deb 22 March 1984 vol 449 c1460WA
Lord Kennet

asked Her Majesty's Government:

Whether they consider it in accordance with international law for a merchant ship on the high seas to be questioned about its origin, destination, and cargo, by a warship of another state.

Baroness Young

The conditions under which a warship which encounters a foreign merchant ship on the high seas may board it are set out in the Geneva Convention on the High Seas of 1958, in particular Article 22.
