United States V. The Amistad - Decision of The Supreme Court

Decision of The Supreme Court

On March 9, Associate Justice Joseph Story delivered the Court's decision. Article IX of Pinckney's Treaty was ruled off topic since the Africans in question were never legal property. They were not criminals, as the U.S. Attorney's Office argued, but rather "unlawfully kidnapped, and forcibly and wrongfully carried on board a certain vessel". The documents submitted by Attorney General Gilpin were not evidence of property, but rather of fraud on the part of the Spanish government. Lt. Gedney and the USS Washington were to be awarded salvage from the vessel for having performed "a highly meritorious and useful service to the proprietors of the ship and cargo".

When La Amistad came into Long Island, however, the Court believed it to be in the possession of the Africans on board, who had no intent to become slaves. Therefore, the Adams-Onís Treaty did not apply, and the President was not required to return the slaves to Africa.

Upon the whole, our opinion is, that the decree of the circuit court, affirming that of the district court, ought to be affirmed, except so far as it directs the negroes to be delivered to the president, to be transported to Africa, in pursuance of the act of the 3rd of March 1819; and as to this, it ought to be reversed: and that the said negroes be declared to be free, and be dismissed from the custody of the court, and go without delay.
