Substantive Due Process Bars Predatory-Offender Registration Triggered by a Predatory Charge Ending in a Trial Judgment of Acquittal
1. Introduction
In Chad Loran Siegel v. Drew Evans (Minn. Aug. 19, 2026), the Minnesota Supreme Court confronted a distinctive feature of Minnesota’s predatory-offender-registration regime: Minnesota Statutes section 243.166, subdivision 1b(a)(1), can require registration not only when a person is convicted of an enumerated “predatory offense,” but also when the person was charged with such an offense and later convicted of another offense arising out of the same set of circumstances. Minnesota is “unique—or nearly unique” in using this “charged with” trigger so broadly. (Citing State v. Berry, 959 N.W.2d 184, 187 n.3 (Minn. 2021).)
Appellant Chad Loran Siegel was charged with kidnapping (an enumerated predatory offense) alongside attempted second-degree murder and first-degree assault. At trial, the district court entered a judgment of acquittal on the kidnapping counts for insufficient evidence. The jury acquitted Siegel of attempted murder but convicted him of assault (not an enumerated registrable offense). Nevertheless, the Bureau of Criminal Apprehension (BCA) required him to register based on the initial kidnapping charge and the assault conviction.
The case raised a narrow but consequential question: even assuming the statute can be read to require registration in this posture, does imposing registration after a trial judgment of acquittal on the predicate predatory charge violate substantive due process under the Minnesota Constitution?
2. Summary of the Opinion
The court held that requiring a person to register as a predatory offender under Minn. Stat. § 243.166, subd. 1b(a)(1), when the person was charged with a predicate predatory offense but was later acquitted of that predicate offense by the district court’s entry of a judgment of acquittal at trial, violates substantive due process under the Minnesota Constitution.
The court reversed the court of appeals on the merits and remanded to the court of appeals to address an issue it did not reach: whether Siegel’s action is barred by the statute of limitations. The majority expressly declined to resolve the parties’ dispute over the proper statutory interpretation of “charged with,” deciding the case on constitutional “as-applied” grounds instead.
A concurrence/dissent agreed with the majority’s constitutional analysis but argued the court should have resolved the case on the statute of limitations without reaching the constitutional question, invoking constitutional avoidance and warning against an advisory opinion.
3. Analysis
3.1. Precedents Cited
Registration statute framework and earlier approval in plea-bargain contexts
-
Boutin v. LaFleur, 591 N.W.2d 711 (Minn. 1999)
This is the key substantive due process precedent involving Minn. Stat. § 243.166’s “charged with” trigger. In Boutin, the defendant was charged with predatory sexual offenses but pleaded guilty to a non-predatory assault offense; the predatory charges were dismissed as part of the plea. The court upheld registration as rationally related to the legitimate state interest of solving crimes, emphasizing the Legislature’s 1993 expansion of the statute “to ensure that true predatory offenders cannot plead out of the registration requirements” (as later summarized in State v. Lopez, 778 N.W.2d 700, 704–05 (Minn. 2010)).
The Siegel majority treats Boutin as validating the statute in the “plea-bargain evasion” scenario the Legislature had in mind—but not as resolving whether registration remains rational when the predicate predatory charge has been rejected at trial through a legal acquittal for insufficient evidence.
-
Werlich v. Schnell, 958 N.W.2d 354 (Minn. 2021)
Cited for the proposition that as-applied constitutional challenges may yield different outcomes in different factual contexts and that the court is “not necessarily bound” by Boutin to uphold every application of § 243.166. The majority uses Werlich to support tailoring substantive due process analysis to the precise posture presented.
-
Kaiser v. State, 641 N.W.2d 900 (Minn. 2002) and Doe v. Poritz, 662 A.2d 367 (N.J. 1995)
These cases are used to describe the public safety policy rationale for registration—society’s asserted right to know of predatory offenders’ presence and law enforcement’s interest in tracking a defined class of offenders—while also noting that Minnesota’s registration information is generally nonpublic with limited disclosure exceptions.
-
State v. Lopez, 778 N.W.2d 700 (Minn. 2010)
Lopez supplies statutory history and structure: the registry began (1991) as conviction-based; in 1993 it expanded to cover persons charged with predatory offenses but convicted of other offenses arising out of the same circumstances to prevent “pleading out” of registration.
-
State v. Berry, 959 N.W.2d 184 (Minn. 2021)
Cited to underscore Minnesota’s near-uniqueness in imposing registration based on being charged with a predatory offense rather than convicted of it.
Minnesota substantive due process method (rational basis with anti-arbitrariness component)
-
Fletcher Props., Inc. v. City of Minneapolis, 947 N.W.2d 1 (Minn. 2020)
Provides the three-part rational basis framework the court applies under the Minnesota Constitution: (1) permissible public purpose; (2) rational connection between means and ends; and (3) whether the Legislature acted arbitrarily or capriciously, including whether the rule emerged from reasoned deliberation and provides sufficiently definite standards.
-
State v. Holloway, 916 N.W.2d 338 (Minn. 2018) and Rew v. Bergstrom, 845 N.W.2d 764 (Minn. 2014)
Cited for selecting rational basis review (no fundamental right implicated) and for the nature of as-applied challenges (“in the context of the specific circumstances presented”).
-
Miller Brewing Co. v. State, 284 N.W.2d 353 (Minn. 1979), Minnesota v. Clover Leaf Creamery Co., 449 U.S. 456 (1981), and Contos v. Herbst, 278 N.W.2d 732 (Minn. 1979)
These authorities are invoked through Fletcher Props. to ground the deferential but still meaningful Minnesota rational basis inquiry, including reliance on legislative facts and judicially noticeable facts.
-
Weinberger v. Salfi, 422 U.S. 749 (1975)
Used for the concept of prophylactic rules: the Legislature may constitutionally adopt broad categorical solutions even if imprecise, but Minnesota’s due process analysis still bars arbitrary and capricious burdens falling outside the rational scope of the statute’s purposes.
Meaning and consequences of acquittal
-
McElrath v. Georgia, 601 U.S. 87 (2024) and State v. Wakefield, 278 N.W.2d 307 (Minn. 1979)
These cases supply the court’s treatment of acquittals as legally significant determinations. The majority acknowledges that acquittal does not always equal factual innocence, but emphasizes the jurisprudential commitment that, once the State fails to prove guilt, the acquitted person is treated as innocent “in the eyes of the law.” That principle is especially weighty where the acquittal is entered as a matter of law through a judgment of acquittal for insufficient evidence.
Procedure on remand and issues not reached
Constitutional avoidance and statute of limitations (concurrence/dissent)
-
Byington v. State, 981 N.W.2d 193 (Minn. 2022) and State v. Bourke, 718 N.W.2d 922 (Minn. 2006)
Invoked for the constitutional avoidance principle: courts generally should not reach constitutional questions if a case can be resolved on non-constitutional grounds.
-
State v. North Star Res. & Dev. Inst., 200 N.W.2d 410 (Minn. 1972) and Schowalter v. State, 822 N.W.2d 292 (Minn. 2012)
Used to argue that deciding constitutional questions unnecessarily risks issuing advisory opinions and deciding cases merely to establish precedent.
-
Thiele v. Stich, 425 N.W.2d 580 (Minn. 1998) and Nicollet Restoration, Inc. v. City of St. Paul, 533 N.W.2d 845 (Minn. 1995)
Cited to show the statute-of-limitations issue was properly presented and preserved.
-
Franklin v. Evans, 992 N.W.2d 379 (Minn. 2023)
Supplies the limitations rule for § 1983 challenges to predatory registration: a six-year limitations period applies and accrual occurs when the person “was first required to register.” The concurrence/dissent reasons that Siegel’s claim accrued in February 2014 (sentencing notice), making the January 2023 filing untimely.
3.2. Legal Reasoning
(a) The court sidesteps statutory interpretation to decide an as-applied Minnesota constitutional question
The parties disputed whether Siegel remained “charged with” kidnapping after the district court entered a judgment of acquittal. The BCA advanced a “time of charging” theory: the statutory “charged with” condition is satisfied by the historical fact of having been charged at the outset, even if the charge later collapses at trial. The majority assumed (without deciding) that the BCA’s interpretation could apply and held that, even if it did, compelling registration on these facts violates substantive due process under Minn. Const. art. I, § 7.
(b) Rational basis review applies, but Minnesota’s rational basis includes a non-arbitrariness inquiry
Because Siegel did not establish that registration in these circumstances burdened a fundamental right, the majority applied rational basis review (citing State v. Holloway, Boutin v. LaFleur, and Werlich v. Schnell). Yet the analysis is not purely deferential: Fletcher Props., Inc. v. City of Minneapolis requires the court to ask (1) whether the objective is permissible, (2) whether the Legislature could rationally believe the chosen mechanism serves that objective, and (3) whether the enactment/operation is arbitrary or capricious.
(c) The majority accepts the registry’s general purposes but finds the “judgment-of-acquittal” application breaks the means-ends fit
The court described two related purposes: public safety and assisting law enforcement to investigate/solve crimes by tracking a defined class of likely-to-reoffend offenders (drawing from Kaiser v. State, Doe v. Poritz, and Boutin v. LaFleur). It emphasized that the Legislature limited registration to enumerated predatory offenses based on recidivism concerns and that the 1993 amendment targeted a specific loophole—avoiding registration through plea deals (State v. Lopez).
That legislative rationale, the court held, does not extend to a defendant who obtains a trial judgment of acquittal on the predicate predatory charge:
-
No “pleading out” problem exists. The chief justification for the “charged with” trigger—preventing true predatory offenders from bargaining away registration—does not apply where a trial court determines that no reasonable jury could convict on the predatory charge.
-
The acquittal is legally weighty. Relying on McElrath v. Georgia and State v. Wakefield, the court treated a judgment of acquittal as an especially strong legal conclusion that the State’s evidence failed as a matter of law, making the connection between the person and the class of “predatory offenders” too attenuated to justify registration for public safety purposes.
-
Lack of supporting legislative facts. The court found no record support—and the BCA provided none—showing that people convicted of non-enumerated offenses (here, first-degree assault) but acquitted (as a matter of law) of the enumerated predatory charge present the kind of recidivism risk the registry was designed to address.
(d) The application is also “arbitrary and capricious” under Minnesota’s due process doctrine
The majority separately grounded its holding in the third Fletcher Props. factor: arbitrariness. It reasoned that requiring registration after a judgment of acquittal appears less like a deliberatively chosen extension of the registry and more like an accidental overreach—“chance, whim, or impulse”—because nothing indicates the Legislature considered this scenario or supported it with evidence.
The court also highlighted an internal inconsistency: the Legislature’s decision not to make first-degree assault a registrable offense reflects a legislative judgment that assault convictions, standing alone, are not within the registry’s targeted class; using an acquitted predatory charge to transform that same assault conviction into a registrable case was deemed arbitrary.
(e) Scope caution: the holding is narrow
The majority repeatedly confined its decision to the “specific circumstances presented”—a predicate predatory charge followed by a district court’s judgment of acquittal at trial. The opinion explicitly declined to address whether a not-guilty jury verdict or a post-verdict judgment of acquittal would raise the same constitutional problem.
(f) The concurrence/dissent: constitutional avoidance and limitations
Justice McKeig (joined by Justice Moore, III) agreed on the constitutional merits but argued the court should not reach them. Citing Byington v. State and State v. Bourke, the dissent contended the case should be decided on limitations grounds under Franklin v. Evans: a six-year limitations period accrued when Siegel was first required to register (February 2014), making his January 2023 action untimely. Deciding the constitutional question, the dissent warned, risks producing an advisory opinion in tension with State v. North Star Res. & Dev. Inst. and Schowalter v. State.
3.3. Impact
(a) Immediate doctrinal effect: a new as-applied substantive due process limit on § 243.166
The decision establishes a constitutional boundary: even if Minn. Stat. § 243.166, subd. 1b(a)(1), is interpreted to require registration based on a predicate predatory charge, substantive due process under the Minnesota Constitution forbids imposing that consequence when the predicate charge ended in a trial judgment of acquittal.
(b) Practical consequences for litigation and administration
-
Registration challenges. Individuals who were required to register based on a predatory charge that was later disposed of via judgment of acquittal have a newly recognized constitutional theory to challenge registration—subject to statutes of limitation and procedural hurdles the court left open.
-
BCA policy and enforcement. The BCA’s “time of charging” approach, at least as applied to judgments of acquittal, is constitutionally vulnerable. Agencies and sentencing courts may need to verify whether a registrable “charge” survived trial in a legally meaningful way.
-
Legislative response pressure. Because the court did not decide the statutory meaning of “charged with,” the Legislature may choose to clarify the statute’s operation after acquittals to avoid inconsistent applications and future constitutional litigation.
(c) Broader signal: Minnesota’s rational basis review has teeth in “collateral consequence” settings
Although rational basis review is deferential, the opinion shows Minnesota courts will examine whether a collateral civil burden remains connected to the Legislature’s articulated purposes, and will invalidate applications that appear untethered to evidence or legislative deliberation—particularly where Minnesota’s approach is already an outlier among states (State v. Berry).
4. Complex Concepts Simplified
-
Predatory-offender registration (Minn. Stat. § 243.166): A legal requirement that certain offenders provide identifying and location information to law enforcement. In Minnesota it can be triggered by conviction of enumerated offenses and, in some circumstances, by being charged with an enumerated offense and convicted of another offense from the same incident.
-
“Judgment of acquittal”: A ruling by the judge—usually after the State rests—that the evidence is legally insufficient for any reasonable jury to convict, resulting in acquittal as a matter of law.
-
Substantive due process: A constitutional limit on what government may do to people, even if procedures are followed. The question is whether the law (or its application) is a reasonable, non-arbitrary way to pursue a legitimate public purpose.
-
As-applied challenge: An argument that a law may be valid in general but is unconstitutional in the specific circumstances of a particular person.
-
Rational basis review (Minnesota style): The court asks whether the law serves a permissible purpose, whether the means reasonably relate to that purpose, and whether the law’s operation is arbitrary or capricious (Fletcher Props., Inc. v. City of Minneapolis).
-
Constitutional avoidance: A doctrine counseling courts to decide cases on non-constitutional grounds when possible, to avoid unnecessary constitutional rulings (cited in the concurrence/dissent via Byington v. State and State v. Bourke).
5. Conclusion
Chad Loran Siegel v. Drew Evans marks a significant, fact-specific limitation on Minnesota’s already unusual “charged with” registration trigger. The court held that substantive due process under the Minnesota Constitution is violated when the State compels predatory-offender registration based on a predicate predatory charge that did not merely get dismissed or bargained away, but was rejected at trial through a judgment of acquittal for insufficient evidence. The ruling distinguishes Boutin v. LaFleur as a plea-bargain-evasion case and underscores that even under rational basis review, Minnesota courts will invalidate applications that become arbitrary—especially when they extend beyond the Legislature’s evident aims and supporting record.
The ultimate relief for Siegel remains uncertain pending remand on the statute of limitations question—an uncertainty highlighted by the concurrence/dissent’s constitutional avoidance critique. Nonetheless, the precedent reshapes the constitutional landscape for predatory-offender registration in Minnesota: an acquitted predatory charge, at least when the acquittal occurs by judgment of acquittal at trial, cannot constitutionally be used as the predicate to brand and regulate someone as a “predatory offender.”
