Reynolds v. United States
The Supreme Court ruled that a federal sex-offender registration law did not apply to people convicted before the law was passed until the Attorney General formally said it applied to them.
Because the Attorney General did not issue that rule until seven months after the law took effect, offenders convicted earlier could not be prosecuted for failing to register during that gap unless the rule itself was valid — a question the Court sent back to the lower court to resolve.
“In our view, these provisions, read together, mean that the Act’s registration requirements do not apply to pre-Act offenders until the Attorney General specifies that they do apply.”
The Court's central holding on when the registration duty for past offenders took effect.
How it got here: A federal trial court rejected Reynolds' challenge to the registration rule on the merits, but the Third Circuit ruled against him without addressing that challenge; Reynolds asked the Supreme Court to resolve a circuit split.
The Case in Depth
What happened
Billy Joe Reynolds was convicted of a sex offense in Missouri in 2001, served prison time, and registered as a sex offender there. After a new federal law required registration in every jurisdiction where offenders live, work, or study, Reynolds moved to Pennsylvania in 2007 without updating his registration. He was indicted for failing to register during that move.
The question before the Court
Did a federal sex-offender registration law automatically require people convicted before it was passed to register, even before the Attorney General said the law applied to them?
The Court's answer
No — the Court ruled that the registration law's requirements did not automatically apply to people convicted before the law existed. Instead, those requirements only kicked in once the Attorney General formally specified that they applied to this group, which happened in February 2007, about seven months after the law took effect.
Because Reynolds was accused of failing to register in September and October 2007 — after that rule was issued — the case turns on whether the Attorney General's rule was itself valid. The Court sent that question back to the lower courts, since the Court of Appeals had never addressed it.

Why it matters
The ruling affects when pre-2006 sex offenders could be criminally prosecuted for not registering under the new federal system. It means prosecutors cannot charge people convicted before the law existed with failing to register unless the Attorney General had validly triggered the requirement for them, adding a legal hurdle in cases involving that early time window.
What changes now
The case returns to the lower courts to decide whether the Attorney General's February 2007 rule applying the registration requirement to pre-Act offenders was itself valid, since Reynolds had argued it violated constitutional and administrative-law rules. If that rule is upheld, Reynolds could still be liable; if struck down, the charge covering the September–October 2007 period may not stand.
What this does not decide
The Court did not decide whether the Attorney General's Interim Rule was itself lawful under the nondelegation doctrine or federal rulemaking procedures — that question was left for further proceedings on remand.
Concurrences and dissents
Dissent — Justice Scalia
Justice Scalia argued the registration requirement applied automatically to pre-Act offenders without any action by the Attorney General, and that the 'authority to specify applicability' provision was better read as letting the Attorney General carve out exceptions rather than switch the duty on. He found the majority's baseball-commissioner analogy inapt and warned that reading the statute as giving the Attorney General unchecked discretion over whether the law applied at all raised serious nondelegation concerns.
How the Court got there
The legal reasoning, step by step
- The Court read the statute as four linked statements: a general registration duty, an initial-registration timing rule, an update rule, and a fourth provision letting the Attorney General 'specify the applicability' of the registration duty to people convicted before the law existed.
- Applying the ordinary interpretive principle that a specific provision controls over a general one, the Court treated the fourth, pre-Act-specific statement as governing how the general registration duty applies to pre-Act offenders, rather than treating both as independently operative.
- The Court read 'authority to specify the applicability' as granting power to turn the requirement on for this group, not power to carve out exceptions from a duty that already applied to them by default.
- The Court reasoned this reading made practical sense: Congress may have wanted the Justice Department, which implements the law, to sort out how to phase in registration for a large, varied group of pre-existing offenders rather than impose the duty on all of them immediately.
- The Court also concluded this reading avoided leaving gaps in the law unclear, since applying the duty immediately to pre-Act offenders would have required judges to invent unstated deadlines the statute never provided, creating exactly the kind of vagueness criminal law is supposed to avoid.
- The Court rejected the government's arguments that this reading undermined the law's purpose or produced absurd delays, concluding instead that the Attorney General retained ample power and incentive to activate the requirement promptly, as in fact happened here.
