its obligation on the courts of the United States must be admitted. Marshall goes on to say that, ? yet where a treaty is the law of the land, and as such affects the rights of parties litigating in court, that treaty as much binds those rights and is much to be regarded by the court as an act of congress; and although restoration may be an executive, when viewed as a substantive, act independent of, and unconnected with, other circumstances, yet to condemn a vessel, the restoration of which is directed by a law of the land, would be a direct infraction of that law, and of consequence, improper.?
