Montana SVORA: DOJ Must Obtain Judicial Determination and Courts May Not Use Unproven Charging Allegations to Impose Registration for Foreign Convictions

Case: Wesley Thomas Cooper v. Montana Department of Justice, Division of Criminal Investigation, 2026 MT 4 (DA 25-0414)
Court: Supreme Court of Montana
Date: January 13, 2026
Disposition: Reversed and remanded with instructions

1. Introduction

This appeal arose after the Montana Department of Justice (DOJ) notified Wesley Thomas Cooper that he must register in Montana as a sex offender under the Sexual or Violent Offender Registration Act (SVORA). Cooper’s underlying conviction was in North Dakota for misdemeanor “Sexual Assault” under N.D. Cent. Code § 12.1-20-07(1)(a). His plea agreement stated he was not required to register in North Dakota, and it did not include an admission of the victim’s age.

The DOJ nevertheless determined Cooper had a Montana registration duty by treating his North Dakota offense as “reasonably equivalent” to Montana’s sexual assault registration-triggering provision and by relying on the victim age alleged in the original North Dakota charging Information (which alleged a 2013 birth year). Cooper sought a writ of prohibition in Montana district court to prevent the DOJ from enforcing registration. The district court denied the writ and required registration.

The Montana Supreme Court addressed three core issues: (1) whether prohibition was an appropriate procedural vehicle; (2) whether a court/agency may rely on unproven allegations (e.g., victim age in an information) to impose registration; and (3) whether North Dakota’s sexual assault statute is “reasonably equivalent” to a Montana registrable “sexual offense” under the applicable statutory version.

2. Summary of the Opinion

3. Analysis

3.1 Precedents Cited

A. Standards of review and writ practice

• Allied Waste Servs. of N. Am., LLC v. Dep't of Pub. Serv. Regul. — Cited for the proposition that issuing/denying prohibition is reviewed as a legal conclusion regarding statute application.
• Langford v. State — Reinforces de novo review of statutory interpretation/application.
• State v. Lund — Analogizes registration duty determinations to legal questions like sentence enhancement use of prior convictions.
• State v. Spady — Cited for the standard when reviewing constitutional law conclusions (correctness of interpretation).
• Kimble Props., Inc. v. State Dep't of State Lands — Supplies the statutory definition of prohibition (arresting proceedings by bodies exercising judicial functions) and the Court’s “strong disinclination” to grant it.
• Bitterroot River Prot. Ass'n v. Bitterroot Conservation Dist. — Emphasizes prohibition is reserved for “extreme necessity.”
• Malta Irrigation Dist. v. Mont. Bd. of Health & Env't Scis. — Central comparator: prohibition denied there because an administrative process existed and judicial review supplied a “plain, speedy, and adequate” remedy; also articulates what “speedy” and “adequate” mean in this context.

B. Temporal application of law

• Med. Marijuana Growers Ass'n, Inc. v. Corrigan — Used to apply “the law in effect at the time the crime was committed,” leading the Court to apply the 2015 Montana statutes, not the 2019 versions referenced by DOJ.

C. Punitive nature of registration (triggering constitutional constraints)

• State v. Hinman — Pivotal: SVORA “as amended since 2007” is punitive, placing “onerous, life-long affirmative restraints” and excessive burdens relative to civil regulatory aims. This characterization undergirds the Court’s importation of sentencing-enhancement constitutional doctrine (Apprendi line) into the registration-duty analysis.

D. Federal constitutional doctrine on judicial factfinding (Apprendi line)

• In re Winship — Due process requires proof beyond a reasonable doubt of facts necessary to constitute the crime charged.
• Apprendi v. New Jersey — The anchor rule: any fact (other than prior conviction) that increases the penalty beyond the statutory maximum must be submitted to a jury and proved beyond a reasonable doubt.
• Blakely v. Washington — Clarifies “statutory maximum” for Apprendi purposes as the maximum sentence based solely on facts reflected in the verdict or admitted by the defendant.
• Shepard v. United States — Reinforces the jury’s constitutional role as a shield against state power and requires jury findings for disputed facts essential to raise the sentence ceiling.
• Descamps v. U.S. — Provides both Sixth Amendment concerns about judicial factfinding and the contours of the “modified categorical approach.” The Court relied on Descamps to reject fact-based expansion beyond identifying the elements of the conviction, especially where the statute is indivisible.

E. “Modified categorical approach” debate and Ninth Circuit cases

• U.S. v. Mi Kyung Byun — DOJ invoked this to support examining underlying documents; the Court distinguished it because Byun involved (i) an admission of the victim’s age and (ii) federal SORNA, which many circuits treat as non-punitive.
• U.S. v. Elkins — Cited (with note 7) for the proposition that Ninth Circuit and other circuits have treated federal SORNA as non-punitive—contrasting with Montana SVORA after Hinman.
• U.S. v. Cabrera-Guitierrez — Quoted for the point that Descamps forecloses the modified categorical approach for indivisible statutes.
• U.S. v. Aguila-Montes de Oca — Mentioned as the Ninth Circuit decision chastised in Descamps for overextending judicial factfinding beyond recognition of a prior conviction.

F. Montana authority on “reasonable equivalency,” enhancements, and burden

• State v. Scott — Supplies the Montana “elements comparison” test for “reasonably equivalent” statutes and the principle that the State must prove qualifying facts for enhancement-like consequences; the Court used Scott’s framework to compare North Dakota and Montana offenses and to reject burden-shifting to the defendant.
• State v. Beam — Quoted (through Scott) for the rule that a district court has no power to impose a sentence absent specific statutory authority.
• Sandstrom v. Montana — Invoked to caution against shifting the burden of persuasion to the defendant, reinforcing that DOJ’s suggestion would be constitutionally problematic.

3.2 Legal Reasoning

Issue 1: Prohibition vs. petition for removal

The district court reasoned Cooper should proceed via § 46-23-506, MCA (petition for removal after years of registration). The Supreme Court rejected that as an “adequate remedy” because it would require Cooper to endure SVORA’s punitive burdens first. The Court’s reasoning is built from:

• Malta Irrigation Dist.’s “plain, speedy, and adequate” requirement, and its emphasis that a remedy is inadequate where slowness produces immediate injury.
• Hinman’s characterization of SVORA as punitive, which makes forced compliance itself a cognizable harm, not merely an administrative inconvenience.
• The absence of any administrative or statutory mechanism (and judicial review) to challenge DOJ’s foreign-conviction registration determination.

Critically, the Court reframed the institutional role: deciding whether a foreign conviction triggers SVORA is “always a conclusion of law” and therefore should be made by a court—promptly and with process—not imposed by an executive agency without oversight.

Issue 2: Reliance on unproven allegations (victim age) to impose registration

This was “a matter of first impression” in Montana’s SVORA context. The Court treated SVORA registration—post-Hinman—as akin to a punishment-enhancing consequence. That move is doctrinally important: it activates Apprendi/Blakely/Shepard constraints against judicial (or agency-driven) factfinding that increases punishment.

The DOJ’s determination depended on the victim’s age alleged in the North Dakota Information. But an Information reflects probable cause allegations, not necessarily facts found beyond a reasonable doubt. Cooper did not admit the victim’s age in his plea agreement; North Dakota did not prove it to a jury; and Cooper contested it.

The Court held that using those allegations to trigger Montana registration violates due process and jury-trial principles because it effectively increases punishment beyond what the guilty plea authorizes. It also rejected any implicit burden-shifting approach whereby Cooper would have to disprove the Information’s allegations, citing State v. Scott and Sandstrom v. Montana.

Issue 3: “Reasonably equivalent” comparison—law vs. allegations; elements vs. facts

Independently of constitutional doctrine, the Court anchored its decision in statutory text:

• § 46-23-502(9)(b), MCA (2015) requires registration for “any violation of a law of another state … reasonably equivalent” to listed Montana violations (emphasis in Opinion).
• § 1-2-101, MCA prohibits courts from inserting what the Legislature omitted (supporting a law-to-law comparison rather than allegation-to-law).
• § 46-1-401(1)(d), MCA prohibits penalty enhancements unless a guilty-pleading defendant also admitted the enhancing fact—reinforcing the elements/admissions boundary.

Applying State v. Scott’s elements comparison method, the Court identified the dispositive mismatch:

• Montana registrable sexual assault under § 45-5-502(3), MCA (2015) requires (among other elements) that “the victim is less than 16 years of age” and the offender is at least 3 years older.
• North Dakota misdemeanor sexual assault under N.D. Cent. Code § 12.1-20-07(1)(a) has no age element.

Because the age element is essential to Montana’s registration-triggering variant, the North Dakota statute is not “reasonably equivalent” to the listed registrable Montana offense. The Court therefore held Cooper has no Montana registration duty on this conviction record.

3.3 Impact

1) Procedural restructuring of SVORA enforcement for foreign convictions

The Opinion’s most institutionally significant statement is that DOJ should not unilaterally impose SVORA registration based on its own legal conclusions about foreign convictions. Instead, the “proper procedure” is for DOJ to initiate a district court action and serve the affected person. Practically, this creates a strong expectation of:

• Judicial gatekeeping before punitive registration obligations attach in foreign-conviction cases.
• Adversarial testing of “reasonable equivalency” and the permissible scope of record materials.

2) Elements-and-admissions limitation on record review

The Court drew a hard line: when SVORA consequences depend on facts like victim age, those facts must come from the permissible conviction record (jury findings or defendant admissions), not merely charging allegations. This has immediate relevance for:

• Foreign plea bargains where prosecutors reduce charges and omit aggravating facts (e.g., age) from the plea admissions.
• Any Montana attempt to use informations/complaints/police narratives to supply missing elements for registration-triggering equivalency.

3) “Reasonably equivalent” becomes tighter in registration cases

By treating SVORA as punitive (Hinman) and coupling that with Scott’s elements test, the Court’s approach narrows when foreign offenses will qualify—especially where Montana’s registrable offense includes extra elements (e.g., age differentials) not present in the foreign statute.

4) Administrative law and due process implications

The Court highlighted the absence of an administrative review mechanism as a reason prohibition was necessary. The Legislature may respond by creating a formal administrative contest process with judicial review. Until then, litigants will likely invoke this decision to:

• Challenge DOJ determinations promptly in district court (including by extraordinary writ where appropriate).
• Argue that prolonged compliance-with-first remedies are inadequate when the consequence is punitive.

4. Complex Concepts Simplified

• Writ of prohibition: An extraordinary court order stopping a government actor from proceeding when it is acting outside its lawful power and there is no adequate ordinary remedy.
• SVORA (sex offender registration): Montana’s statutory scheme requiring certain offenders to register; after State v. Hinman, Montana treats modern SVORA burdens as punishment, not merely civil regulation.
• “Reasonably equivalent” statutes: A comparison focused on the elements (what must be proved to convict), not on the alleged factual story. If Montana’s registrable offense requires an element the other state’s statute does not, they are not reasonably equivalent.
• Elements vs. allegations: “Elements” are the legal ingredients of a crime that must be proved (or admitted). “Allegations” in a charging document are claims made to establish probable cause; they are not necessarily proved facts.
• Apprendi principle (in plain terms): Government cannot increase punishment based on disputed facts found by a judge (or agency) under a low standard; those facts must be found by a jury beyond a reasonable doubt or admitted by the defendant.
• Categorical vs. modified categorical approach: Courts generally compare statutes by elements (categorical). The “modified” approach allows limited document review only when the statute is “divisible” (lists alternative elements). The Court found North Dakota’s statute “indivisible,” making expanded factfinding improper.

5. Conclusion

Cooper v. DOJ establishes a clear Montana rule for foreign-conviction SVORA determinations: (1) a writ of prohibition may be necessary and appropriate where DOJ imposes registration without any adequate review process; (2) because SVORA is punitive, Montana courts may not impose registration based on unproven charging allegations—only on facts proved beyond a reasonable doubt or admitted by the defendant; and (3) “reasonable equivalency” is an elements-based comparison to the registrable Montana offense, not to a broader non-registrable counterpart.

The decision meaningfully constrains executive-branch imposition of SVORA duties in foreign-judgment cases and aligns Montana’s registration analysis with core jury-trial and due-process protections when registration functions as punishment.
