Opinion Summary:

Petitioner, a Mexican national, was convicted of murder and sentenced to death by a Texas court. Petitioner sought a stay of execution on the ground that his conviction was obtained in violation of the Vienna Convention on Consular Relations (Vienna Convention), and relied on Case Concerning Avena and Other Mexican Nationals (Avena). The Court held that petitioner's argument was foreclosed by Medellin v. Texas, in which the Court held that neither the Avena decision nor the President's Memorandum purporting to implement that decision constituted directly enforceable federal law. The Court declined to stay the execution so that Congress could consider whether to enact legislation implementing the Avena decision where the Due Process Clause did not prevent a State from carrying out a lawful judgment in light of unenacted legislation that might someday authorize a collateral attack on that judgment. The Court also declined the United State's request that the Court stay the execution until January 2012 in support of "future jurisdiction to review the judgment in a proceeding." Accordingly, the applications for stay of execution was denied and petition for a writ of habeas corpus was denied.
