Marks v. United States
Marks v. United States, 430 U.S. 188, is a case decided by the Supreme Court of the United States that explained how the holding of a case should be viewed where there is no majority supporting the rationale of any opinion.
Background
Petitioners were charged with several counts of transporting obscene materials in interstate commerce, and conspiracy to transport such materials. The conduct that gave rise to the charges covered a period through February 27, 1973, but the trial did not begin until the following October. In the interim, on June 21, 1973, the Supreme Court decided Miller v. California which announced new standards for isolating "hard core" pornography from expression protected by the First Amendment, the third test of which was "whether the work, taken as a whole, lacks serious literary, artistic, political, or scientific value". Petitioners argued in the District Court that they were entitled to jury instructions not under Miller, but under the more favorable formulation of Memoirs v. Massachusetts that expressive material is constitutionally protected unless it is "utterly without redeeming social value."The Court noted that the Constitution's Ex Post Facto Clause is a limitation upon the powers of the Legislature, and does not of its own force apply to the Judicial Branch of government. But the principle on which the clause is based—the notion that persons have a right to fair warning of that conduct which will give rise to criminal penalties—is fundamental to our concept of constitutional liberty.
Petitioners asserted that Miller unforeseeably expanded the reach of the federal obscenity statutes beyond what was punishable under Memoirs. The Court of Appeals rejected this argument, noting that the Memoirs standards never commanded the assent of more than three Justices at any one time, and apparently concluded from this fact that Memoirs never became the law, and therefore the "contemporary community standards" test from the 1957 Roth v. United States applied, which was arguably at least as strict than the Memoirs test.
