Act Petitions: No Credibility Determinations Without an Evidentiary Hearing

Introduction

In Scott County Tyrel Lamar Patterson v. State of Minnesota (Minn. July 22, 2026), the Minnesota Supreme Court addressed a recurring procedural question under the 2023 legislative reforms to aiding-and-abetting felony murder: when may a district court deny a petition to vacate a felony murder conviction without holding an evidentiary hearing?

The appellant, Tyrel Lamar Patterson, pleaded guilty in 2017 to first-degree felony murder under an aiding-and-abetting theory arising out of a 2016 robbery/burglary that resulted in James Herron’s death. After enactment of the Act of May 19, 2023, ch. 52, art. 4, § 24, 2023 Minn. Laws 810, 864-68 (“the Act”), Patterson sought to vacate his conviction. The district court denied relief without a hearing, relying heavily on transcripts/findings from a co-conspirator’s separate trial and concluding Patterson “did in fact cause” Herron’s death—effectively rejecting Patterson’s claim that he was outside when the fatal shot occurred.

The Supreme Court reversed, holding the district court abused its discretion by making a credibility determination without first holding an evidentiary hearing.

Summary of the Opinion

The court held that a district court may not make credibility determinations when deciding a petition for relief under the Act without first holding an evidentiary hearing. Because the district court’s denial turned on an implicit credibility determination (rejecting Patterson’s assertion that he was not present for the fatal shot and concluding he actually caused the death), the district court applied an erroneous view of the law and thus abused its discretion. The case was reversed and remanded for an evidentiary hearing.

Analysis

Precedents Cited

  • State v. Zielinski, 32 N.W.3d 847 (Minn. 2026)
    • Role in this case: Zielinski is the doctrinal linchpin. It (1) articulated key Act standards (including how an applicant shows entitlement to relief) and (2) held that, in Act proceedings, “a district court cannot make credibility determinations without first holding an evidentiary hearing.”
    • How it influenced the outcome: Patterson’s appeal was resolved by applying Zielinski’s rule to the district court’s denial, which necessarily depended on disbelieving Patterson’s version of events.
    • Additional clarification imported from Zielinski: The court highlighted Zielinski’s caution that Act litigation should not “look backwards” to earlier proceedings where the newly required intent-to-cause-death issue was not litigated, underscoring why fact development may be necessary now.
  • Andersen v. State, 913 N.W.2d 417 (Minn. 2018)
    • Role in this case: Andersen supplied the foundational postconviction principle: a court cannot decide disputed factual issues by assessing credibility on a paper record; it must hold an evidentiary hearing.
    • How it influenced the outcome: Although raised late (at oral argument), the Supreme Court treated the issue as controlling, then used Zielinski to confirm Andersen applies “with equal force” under the Act.
  • State ex rel. Roy v. Tahash, 152 N.W.2d 301 (Minn. 1967)
    • Role in this case: Roy provided the classic Minnesota rule for when a hearing is required: an evidentiary hearing is required whenever material facts are in dispute, were not resolved in the original proceedings, and must be resolved to decide the merits.
    • How it influenced the outcome: The court framed Patterson’s dispute—whether he caused the death / was present for the fatal shot—as precisely the kind of unresolved, material factual dispute triggering a hearing.
  • Green v. State, 35 N.W.3d 1 (Minn. 2026)
    • Role in this case: Green was used to confirm the abuse-of-discretion standard applies to Act denials and that the standard is the same whether a court denies relief with or without a hearing.
    • How it influenced the outcome: It supported the court’s analytical framework for reviewing the denial and identifying legal error as an abuse of discretion.
  • State v. Griffin, 24 N.W.3d 247 (Minn. 2025)
    • Role in this case: Griffin established the abuse-of-discretion standard for district court decisions under the Act (there, denial of a preliminary application).
    • How it influenced the outcome: It helped extend that same standard to the specific procedural posture here: denial of a petition under subdivision 6(e)(2) without a hearing.
  • Rhodes v. State, 875 N.W.2d 779 (Minn. 2016)
    • Role in this case: Rhodes provided the definition of abuse of discretion, including when a court bases a ruling on an erroneous view of the law.
    • How it influenced the outcome: The Supreme Court categorized the district court’s mistake—making credibility determinations without a hearing—as an “erroneous view of the law.”
  • State v. Hannuksela, 452 N.W.2d 668 (Minn. 1990) and Hegseth v. Am. Fam. Mut. Ins. Grp., 877 N.W.2d 191 (Minn. 2016)
    • Role in this case: These cases justified the court’s decision to address an issue raised late, invoking the court’s responsibility to decide cases according to law and where “the interests of justice so require.”
    • How they influenced the outcome: They enabled the Supreme Court to reach the dispositive hearing/credibility issue despite its late presentation.
  • In re The Filing of Requests for Relief in Aid and Abet Felony Murder Cases, No. ADM09- 8010
    • Role in this case: Cited for administrative/procedural context about filing and processing Act-related requests.
    • How it influenced the outcome: It did not drive the core holding, but situates Act petitions within the Court’s broader implementation framework.

Legal Reasoning

The Supreme Court’s reasoning proceeds in three steps:

  1. Standard of review: Relying on Green v. State and State v. Griffin, the court confirmed that denial of Act relief—even without a hearing—is reviewed for abuse of discretion, and that legal error qualifies as an abuse of discretion under Rhodes v. State.
  2. Rule governing credibility determinations: Under Andersen v. State, a postconviction court cannot resolve disputed facts by making credibility determinations on a paper record; it must hold an evidentiary hearing. The court then relied on State v. Zielinski to confirm this rule applies to Act proceedings specifically.
  3. Application to Patterson’s denial: The district court denied relief because it found Patterson “did in fact cause” Herron’s death—necessarily disbelieving Patterson’s sworn plea-colloquy narrative that he was outside for the fatal shot. That disputed, material fact had not been resolved in Patterson’s own conviction proceedings and mattered directly under the Act’s eligibility criteria. Under State ex rel. Roy v. Tahash, that scenario requires an evidentiary hearing. Because the district court made the credibility call without a hearing, it acted under an erroneous view of the law.

Notably, the Supreme Court did not decide whether the district court also erred by relying on evidence “outside the record” (i.e., the co-defendant’s trial), because the credibility/hearing error alone required reversal and remand.

Impact

The opinion’s practical significance is procedural but substantial: it reinforces that Act litigation is not a purely “paper” remedy when entitlement turns on disputed historical facts. Key impacts include:

  • More hearings where causation/intent is disputed: If a petitioner’s eligibility turns on “who did what” (caused death, intended death, aided with intent), courts cannot deny relief by choosing between competing narratives without testimony and credibility testing.
  • Constrains summary denials under subdivision 6(e)(2): While the Act permits denial when later submissions show “no reasonable probability” of entitlement, this decision signals that such denials cannot rest on resolving credibility disputes from transcripts alone.
  • Shifts litigation focus to evidentiary development: Parties should expect to identify witnesses, admissibility issues, and the evidentiary record needed to prove (or disprove) causation and intent under the Act’s revised standards.
  • Clarifies the relationship between old convictions and new elements: By echoing State v. Zielinski, the court underscores that earlier proceedings often did not litigate the now-critical “intent to cause death” requirement; Act proceedings may therefore require factfinding rather than deference to prior case posture.

Complex Concepts Simplified

  • First-degree felony murder (aiding and abetting): A murder charge based on a killing that occurs during certain serious felonies. Historically, accomplices could be liable even without an intent to kill if the death was a foreseeable result of the felony.
  • The 2023 change (Minn. Stat. § 609.05, subd. 2a(a)): For first-degree felony murder where “another” causes the death, an accomplice now must have intentionally assisted the other person with the intent to cause death. Foreseeability alone is no longer enough for that category.
  • “Preponderance of the evidence”: The petitioner must show something is more likely true than not (greater than 50% likelihood).
  • “Reasonable probability” (screening concept in Act procedure): A threshold assessment—whether facts alleged and materials submitted suggest the petitioner might be able to prove entitlement at a hearing.
  • Evidentiary hearing: A court session where witnesses can testify under oath, be cross-examined, and where the judge can evaluate credibility firsthand.
  • Credibility determination: Deciding whether to believe one version of events over another. Minnesota law generally forbids making such determinations solely from conflicting written submissions when the dispute matters to the outcome.
  • Abuse of discretion: A reviewing court will reverse when the lower court’s decision is based on legal error, clearly erroneous factfinding, or arbitrary/capricious reasoning.

Conclusion

This decision cements a clear procedural safeguard for Act petitions: district courts may not deny Act relief by resolving disputed, material facts through implicit or explicit credibility determinations on a paper record. When eligibility hinges on contested facts—such as whether the petitioner caused the death or acted with intent to cause death—an evidentiary hearing is required. The ruling thus strengthens the Act’s function as a meaningful retroactive review mechanism rather than a transcript-based re-argument of past proceedings.
