. Article 63 of the Declaration states that "Forcible resistance to the legitimate exercise of the right of stoppage, search and capture involves in all cases the condemnation of the vessel. The cargo is liable to the same treatment as the cargo of an enemy vessel. Goods belonging to the master or owner of the vessel are treated as enemy goods."

It was ultimately decided under a separate article of the Hague conference that postal correspondence of neutrals and even of belligerents, and whether official or private, found on board a neutral or even an enemy ship should be "inviolable", and that though the ship should be detained, this correspondence had to be forwarded to its destination by the captor "with the least possible delay." The only exception to this exemption is correspondence destined for or proceeding from a blockaded port. As regards the mail-ships themselves, apart from this inviolability of the correspondence, no exemption or privilege is extended beyond the injunction that they should not be searched, except when absolutely necessary, and then only "with as much consideration and expedition as possible," which might just as well be said of all ships stopped or searched in international waters
