What it's about

The Court refused to hear his case (denied his petition), so it did not decide that legal question.

Nunes's case came from the U.S. Court of Appeals for the Fifth Circuit and focused on when an error is “plain” under a federal criminal rule.

Question presented

Whether the absence of a binding, on-point decision of either this Court, or of the reviewing court of appeals, is enough for an error not to be “plain” within the meaning of Federal Rule of Criminal Procedure 52(b).
