United States v. Juvenile Male
The Supreme Court threw out a federal appeals court ruling that had struck down applying a national sex-offender registration law to juveniles, because by the time the appeals court decided the case, the young man's registration requirement had already expired and there was no live dispute left to resolve.
The decision does not address whether the registration law is constitutional as applied to juveniles; it simply holds that the appeals court had no authority to reach that question once the case became moot.
“[0]ne can never be certain that findings made in a decision concluding one lawsuit will not some day . . . control the outcome of another suit. But if that were enough to avoid mootness, no case would ever be moot”
Explaining why the precedential value of a ruling cannot by itself keep a moot case alive.
How it got here: The Ninth Circuit ruled for respondent on the merits after his federal supervision expired; the Supreme Court had certified a state-law question to Montana's high court before deciding this case.
The Case in Depth
What happened
As a young teenager, respondent sexually abused a younger boy on a Montana reservation and was adjudicated delinquent under federal juvenile law. He was sentenced to juvenile detention and supervision, later including a requirement to register as a sex offender under a federal law enacted while he was still in custody. He challenged that registration requirement on appeal, arguing it unconstitutionally applied a new law to conduct that predated it.
The question before the Court
After a young man's juvenile sex-offender registration order expired while his appeal was pending, could an appeals court still rule on whether the registration law was unconstitutional?
Why it matters
The ruling wipes out the only appellate decision holding that retroactively applying federal sex-offender registration rules to juveniles violates the Constitution. That leaves the underlying constitutional question unresolved, so juveniles facing similar registration requirements cannot rely on that vacated ruling and must raise the issue anew in future cases.
What changes now
The case is sent back to the Ninth Circuit with instructions to dismiss the appeal as moot, erasing that court's earlier ruling on the constitutional question. The underlying issue of whether retroactively applying sex-offender registration requirements to juveniles violates the Constitution remains undecided and could resurface in a future case with a live dispute, including a related case the Court had already agreed to hear the following term.
What this does not decide
This decision says nothing about whether applying sex-offender registration requirements retroactively to juveniles violates the Constitution's ban on ex post facto laws. It resolves only that the appeals court lacked power to decide that question once the case became moot.

Dissent in part — Justice Ginsburg
These three justices would have sent the case back to the Ninth Circuit to let that court decide the mootness question itself in the first instance, rather than have the Supreme Court resolve mootness and order dismissal directly.
How the Court got there
The legal reasoning, step by step
- Article III of the Constitution requires that a real, live dispute exist at every stage of a case, not just when it was first filed, so courts must keep checking that the case is not moot — meaning no live issue remains to decide.
- When someone challenges only an expired sentence or condition, courts do not automatically assume the case remains live; the person must point to some ongoing 'collateral consequence' — a continuing real-world effect tied to the challenged condition — that a favorable ruling could still fix.
- The Montana Supreme Court, answering a certified question, confirmed that the young man's duty to stay registered as a sex offender under state law does not depend on the validity of his now-expired federal supervision conditions, so a win in this case would not free him from the state registration requirement.
- The Court rejected the idea that a favorable ruling's usefulness as precedent in a possible future lawsuit could keep this case alive, reasoning that if that were enough, no case would ever become moot.
- The Court also rejected the argument that this dispute fit the narrow exception for issues that are too short-lived to litigate but likely to recur for the same person, because the young man has turned 21 and can never again be subject to the kind of juvenile supervision order at issue.
- Because no live controversy remained, the Ninth Circuit lacked the authority under Article III to decide the constitutional merits, so its judgment could not stand.
