Gundy v. United States, No. 17-6086, 588 U.S. ___ (2019), was a United States Supreme Court case that held that 42 U.S.C. § 16913(d), part of the Sex Offender Registration and Notification Act ("SORNA"), does not violate the nondelegation doctrine.^[1][2] The section of the SORNA allows the Attorney General to "specify the applicability" of the mandatory registration requirements of "sex offenders convicted before the enactment of [SORNA]".^[3] Precedent is that it is only constitutional for Congress to delegate legislative power to the executive branch if it provides an "intelligible principle" as guidance.^[4] The outcome of the case could have greatly influenced the broad delegations of power Congress has made to the federal executive branch,^[5] but it did not.^[6]

Herman Avery Gundy was on supervised release for a prior federal offense he had committed when he was convicted of sexual assault in Maryland (a state offense), on October 3, 2005. He was sentenced to 20 years imprisonment and 5 years probation, with 10 of the 20-year sentence suspended. Consequently, on March 23, 2006 he was convicted in federal court of violating his supervised release and sentenced to 2 years imprisonment (to be served consecutively to his sexual assault sentence). After he had served his prison sentence for the sexual assault in state custody, on June 15, 2011, he was transferred to federal custody in Pennsylvania to serve his sentence for violating his supervised release.^[7]

On July 17, 2012, Gundy received permission to travel unsupervised to a residential reentry center in New York. On August 27, 2012, he was released from federal custody. Gundy did not register as a sex offender in either Maryland (where he committed his crime) or New York (his state of residence), and was thus arrested for violating SORNA (18 U.S.C. § 2250). In January 2013, he was indicted for that offense.^[2][7]

Despite being convicted of a sexual offense before the implementation of SORNA, Gundy was still subject to the law. This is the result of 42 U.S.C. § 16913(d), which reads:

The Attorney General shall have the authority to specify the applicability of the requirements of this subchapter to sex offenders convicted before the enactment of this chapter or its implementation in a particular jurisdiction, and to prescribe rules for the registration of any such sex offenders and for other categories of sex offenders who are unable to comply with subsection (b).

The Attorney General decided that this law is applicable to everyone convicted of a sexual offense, making the law retroactive.^[6][8]

On September 20, 2017, Gundy's counsel petitioned for a writ of certiorari to the Court of Appeals for the Second Circuit regarding 4 questions presented:^[11]

(1) Whether convicted sex offenders are "required to register" under the federal Sex Offender Notification and Registration Act ("SORNA") while in custody, regardless of how long they have until release.

(2) Whether all offenders convicted of a qualifying sex offense prior to SORNA's enactment are "required to register" under SORNA no later than August 1, 2008.

(3) Whether a defendant violates 18 U.S.C. § 2250(a), which requires interstate travel, where his only movement between states occurs while he is in the custody of the Federal Bureau of Prisons and serving a prison sentence.

(4) Whether SORNA's delegation of authority to the Attorney General to issue regulations under 42 U.S.C. § 16913(d) violates the nondelegation doctrine.

The Supreme Court granted certiorari, though limited to question 4 of the petition, on March 5, 2018. The Cato Institute, Pacific Legal Foundation, American Civil Liberties Union, Downsize DC Foundation and various other organizations and people filed amici curiae in support of Gundy.^[12]

Oral arguments were held on October 2, 2018.

On June 20, 2019 — nearly a full term after the case was argued — the Supreme Court issued their opinion.

The plurality opinion was written by Elena Kagan, who was joined by Ruth Bader Ginsburg, Stephen Breyer, and Sonia Sotomayor. Justice Kagan found that because SORNA guided the Attorney General to eventually apply the registration requirements to all offenders, it did not violate the nondelegation doctrine.^[6][13]

Justice Samuel Alito wrote a brief opinion concurring in the judgement. He stated that he might wish to revisit the court's approach to nondelegation "[i]f a majority of this Court were willing to reconsider the approach we have taken for the past 84 years", but that the statute at issue in this case was not unique enough. Therefore, he voted with the plurality to affirm.

Justice Neil Gorsuch, joined by Chief Justice John Roberts and Justice Clarence Thomas, filed a dissenting opinion. His opinion referenced and disagreed with Justice Alito's vote, believing that this case would be an appropriate vehicle to revisit nondelegation. He believed that the statute "hand[ed] off to the nation’s chief prosecutor the power to write his own criminal code."

On July 11, 2019, Gundy's counsel filed a petition for rehearing. He argued that Justice Kavanaugh's recusal had influenced Justice Alito to vote as he had and requested that the case be heard before the full court. Simultaneously, another case (Paul v. United States) resting on largely the same facts was appealed to the Supreme Court. The cases' respective rehearing and cert petitions were relisted and distributed at several conferences before both were denied. Justice Kavanaugh wrote a statement respecting the denial of certiorari in Paul, indicating that he too might wish to revisit nondelegation in a future case.^{[citation needed]}
