The case involved Clarice Covert, who had been convicted by a military tribunal of murdering her husband. At the time of her alleged offense, an executive agreement was in effect between the United States and United Kingdom, which permitted US military courts to exercise exclusive jurisdiction over offenses by U.S. servicemen or their dependents. The court initially ruled against Mrs. Covert, but changed its mind and issued a new decision in her favor after her lawyer, Frederick Bernays Wiener, famously made a successful petition for rehearing. This is the only time the Supreme Court, without a relevant change in its membership, has changed its mind as the result of a petition for rehearing.
Opinion of the Court
The Court found: "No agreement with a foreign nation can confer power on the Congress, or on any other branch of Government, which is free from the restraints of the Constitution." The Court's core holding of the case is that U.S. citizen civilians abroad have the right to Fifth Amendment and Sixth Amendment constitutional protections. The Court found it unconstitutional to adjudge U.S. citizen civilians in military courts, under the Uniform Code of Military Justice. The Court agreed with the petitioners, concluding that as United States citizens they were entitled to the protections of the Bill of Rights, notwithstanding that they committed crimes on foreign soil. The Court distinguished Reid from the Insular Cases: The "Insular Cases" can be distinguished from the present cases in that they involved the power of Congress to provide rules and regulations to govern temporarily territories with wholly dissimilar traditions and institutions. Justice Black declared: "The concept that the Bill of Rights and other constitutional protections against arbitrary government are inoperative when they become inconvenient or when expediency dictates otherwise is a very dangerous doctrine and if allowed to flourish would destroy the benefit of a written Constitution and undermine the basis of our government." Justice Harlan's concurred with the judgment of the Court but disagreed with much of Justice Black's reasoning. He held that the court-martial per se was not unconstitutional, being an appropriate application of the Necessary and Proper Clause. Harlan also explicitly stated that this power was not limited by either Article III or the Fifth and Sixth Amendments.
