Moore v. Duckworth

Background

A man who pleaded not guilty by reason of insanity was convicted by an Indiana jury of second-degree murder. The Indiana Supreme Court affirmed that conviction. He then filed a federal habeas petition arguing that the evidence did not prove beyond a reasonable doubt that he was sane when the killing occurred.

Reasoning

The lower federal courts denied relief. The Court of Appeals applied a very narrow rule, saying federal review of sufficiency claims exists only when a state conviction is totally without evidence. The petitioner argued he was entitled to the usual federal review of whether the record could support a guilty verdict. The Supreme Court agreed that Jackson v. Virginia requires that standard, but it found a remand unnecessary here because the state court had carefully reviewed the record and concluded the lay testimony could be credited to prove sanity.

Real world impact

The Supreme Court granted review and affirmed the Court of Appeals’ judgment, so the conviction remains in effect. The decision confirms that federal courts must ask whether the record could support a guilty verdict under the Jackson standard. It also makes clear that, under Indiana law, lay witnesses can provide legally sufficient proof of sanity and a jury may credit that evidence.
