In Cargo of the Brig Aurora v. United States (1813) 11 U.S. 382, the Court considered whether a Presidential proclamation could, by declaring that France had ceased to violate the neutral commerce of the United States, reinstate a legislative Act embargoing British goods. (Id., at 384, 388.) The Court concluded that the proclamation was effective, seeing no sufficient reason why the legislature should not exercise its discretion ... either expressly or conditionally, as their judgment should direct. (Id., at 388.)
