1821. The Amiable Spain. It is one of a series of passports issued by property. In this case, the passport was granted, 1821. The Amiable Isabella. 1821. The Amiable passport was to be conclusive of the neutrality of the ship, and the certificate was to show, that the cargo was not contraband. If these documents are wanting, then the property of the ship is to be established by equivalent testimony; and that being shown to be neutral, will protect the cargo, even if enemy's property, unless, indeed, it consist of contraband articles. The "equivalent testimony" required, must mean, that other documents shall be produced which will prove precisely the same facts that were intended to be proved by the passport and certificate; and not that sort of evidence which the technical rules of the Prize Court demand in a case requiring farther proof. Doubtless the intention of the contracting parties is to be regarded in construing treaties, as it is in the interpretation of all other instruments; but that intention is to be gathered from the words they use. Although there are many treaties consecrating the maxim, that free ships shall make free goods, there is no other example of a treaty stipulating what should be conclusive evidence of the freedom of the ship. The parties to this treaty intended to exclude the jurisdiction of the Prize Courts of the belligerent as far as possible, by forbidding the detention of vessels having the required documents, and where they were carried in for adjudication for want of these documents, limiting the inquiry of the Prize Courts to such testimony as should be equivalent. All the cases cited on the other side, of the supposed exception to the general immunity, are cases arising under treaties or ordinances, merely recognising the principle, that free The Amiable ships should make free goods, without providing any 1821. rule of evidence to establish the national character of the ship, and leaving that question to be determined by the general law of nations. But here the conventional law adopts a new rule of evidence, from which the Court is not at liberty to depart. The learned counsel also argued the question of proprietary interest with great minuteness and ability. The Court directed the cause to be reargued, up- March 4th, on the point as to the form and effect of the passport. The Attorney-General, for the captors and respondents, insisted, that the form of passport to which an effect so important was attributed, not having been annexed to the original treaty, by the contracting parties, could not now be supplied by the judicial tribunals of either. Such an attempt would be an encroachment on the treaty-making power, which, in our government, is exclusively confided to the President and Senate. The office of this Court is to construe, not to make or amend treaties. The treaty (art. 17.) provides, that "the ships and vessels belonging to the subjects or people of the other party, must be furnished with sea letters or passports, expressing the name, property, and bulk of the ship, as also the name and place of habitation of the master of the said ship, that it may appear thereby that the ship really and truly belongs to the subjects of one of the parties, which passport shall be made out and granted according to the form annexed to this treaty." These particulars were required to be inserted for 1820. Isabella. 1821. the purpose of identifying the vessel to which the The Amiable passport was intended to apply, and to satisfy the other contracting party that she is really entitled to the immunities stipulated in the treaty. The passport in the present case was either intended to certify that the ship was Captain Cacho's, or not. The words are, "Captain Cacho, with his Spanish ship called," &c. If Cacho was meant to be certified to be the owner, the claim does not conform to it. He expressly swears that it is not his, but that it belongs exclusively to Munos, who claims. Nobody else can have restitution but the actual claimant, and he is not certified in the passport to be the owner. But the term "his Spanish ship," is evidently a mere figurative expression, and means nothing more than the ship of which he is master. What then is the import of the term "Spanish ship?" A certificate that a ship of a certain name, and bulk, and master, is a Spanish ship, is not a certificate that it is Spanish property, or in other words, the property of Spanish subjects, which is alone intended to be protected by the express terms of the article. A vessel may be a Spanish ship by adoption, by having a license to trade with the Indies, without ceasing to be the property of foreigners, or becoming the property of Spanish subjects. It is not sufficient to certify the national character of the ship merely. There must be a certificate that it is the individual property of particular subjects of Spain, for to such alone does the protection of the treaty extend.
