Whether the constitutional challenges could be reviewed in an appeal from the contempt judgment despite limits on grand-jury witnesses' ability to resist subpoenas.
Holding
Yes. Morrison waived her objection to review by failing to raise it in the District Court, and the objection was not jurisdictional.
Reasoning
Morrison relied on Blair v. United States, which restricts the issues a grand-jury witness may raise after being held in contempt for refusing a subpoena. But she did not object in the District Court when the appellees raised their constitutional claims. The court of appeals therefore could treat the objection as waived, and the Supreme Court declined to revisit it.
The asserted Blair limitation did not concern the existence of an Article III case or controversy. The appellees faced enforceable contempt orders, the parties had a concrete adversarial dispute, and the courts could resolve it. Because the claim was nonjurisdictional, ordinary waiver principles applied.
