Part ARTICLE X
Offences against the present Convention may be verified by all means of proof allowed by the legislation of the country of the court. When the officers commanding the ships of war, or ships specially commissioned for the purpose by one of the high contracting parties, have reason to believe that an infraction of the measures provided for in the present Convention has been committed by a vessel other than a vessel of war, they may demand from the captain or master the production of the official documents proving the nationality of the said vessel. The fact of such document having been exhibited shall then be endorsed upon it immediately. Further, formal statements of the facts may be prepared by the said officers, whatever may be the nationality of the vessel incriminated. These formal statements shall be drawn up in the form and in the language used in the country to which the officer making them belongs; they may be considered, in the country where they are adduced, as evidence in accordance with the laws of that country. The accused and the witnesses shall have the right to add, or to have added, thereto, in their own language, any explanations they may consider useful. These declarations shall be duly signed.
