On September 19, 1910, at The Hague, plenipotentiaries of the following nations: Germany, United States of America, Argentine Republic, Austria-Hungary, Chile, Denmark, Spain, France, Great Britain, Japan, Norway, Netherlands and Sweden, signed an instrument entitled Protocole Additionnel á la Convention XII de la Haye du 18 Octobre, 1907. The protocol is by its own provisions (Art. 8) to be considered as forming an integral part of the Convention creating the International Court of Prize; and the acceptance of the protocole additionnel is likewise made a sine qua non to the acceptance of the original convention.
The protocole additionnel seeks to create a different remedy and a modified procedure par dérogation to Articles 28 (paragraph one), 29 and 45 (paragraph two) of the Prize Court Convention and by eliminating Article 8 of the convention entirely and substituting therefor a method preserving the appearance of an action de novo in the International Court and confining its judgment to the ascertainment of the damages to be allowed an injured claimant. It is the practical embodiment of the voeu adopted by the London Naval Conference in 1909 at the instance of the delegation of the United States (acting under instructions from their government); and is intended to offer a means whereby certain nations named as parties to the protocol may obviate constitutional difficulties in the way of their ratifying the original convention.
