Exclusivity of Summary-Denial Grounds and Hearing-First Credibility in Minnesota’s Aid/Abet Felony-Murder Relief Act

Introduction

State of Minnesota v. Melissa Madelyne Zielinski (Minn. Mar. 25, 2026) addresses the gatekeeping stage of a 2023 Minnesota statutory scheme creating a path to limited postconviction relief for certain individuals convicted of first- or second-degree felony murder under an aiding-and-abetting theory. The appeal arose after the Anoka County district court summarily denied Melissa Zielinski’s preliminary application under the Act of May 19, 2023, ch. 52, art. 4, § 24, 2023 Minn. Laws 810, 864-68 (the Act).

The core dispute was procedural but consequential: whether a district court may “summarily deny” a preliminary application for reasons beyond those expressly listed in the Act, and what it means for an applicant to show a “reasonable probability” of entitlement to relief—particularly where the applicant’s intent to cause death was never litigated at trial under the pre-2023 felony-murder aiding-and-abetting framework.

The parties were the State of Minnesota (respondent) and Melissa Madelyne Zielinski (appellant), who was convicted of first-degree felony murder under Minn. Stat. § 609.185(a)(3) based on an aiding-and-abetting theory (Minn. Stat. § 609.05), stemming from a robbery during which her brother shot and killed Karl Henderson.

Summary of the Opinion

The Minnesota Supreme Court reversed and remanded, announcing three controlling rules (as reflected in the syllabus):

  1. A district court may summarily deny a preliminary application under the Act only for the reasons enumerated in subdivision 5(e)-(f).
  2. For applicants convicted of first-degree felony murder, the “reasonable probability” threshold is met if the application alleges facts that would cause a rational person to believe the applicant might prove at an evidentiary hearing, by a preponderance of the evidence, that the applicant neither caused the death nor intentionally aided (etc.) another with the intent to cause death.
  3. In evaluating relief under the Act, the district court may not make credibility determinations without first holding an evidentiary hearing under subdivision 6.

Applying these principles, the Court held the district court abused its discretion by issuing a summary denial “based on the underlying facts” (a rationale not listed in subdivision 5(e)-(f)), and further concluded Zielinski’s allegations satisfied the reasonable-probability threshold because her intent to cause death had not been litigated or rejected in prior proceedings.

Analysis

1) Precedents Cited

The opinion’s reasoning is built from several doctrinal lines: (i) the nature of aiding-and-abetting liability; (ii) standards of review for Act determinations; (iii) statutory interpretation tools; and (iv) postconviction norms regarding credibility and hearings.

Aiding-and-abetting as a theory, not an offense

  • State v. Ezeka, 946 N.W.2d 393 (Minn. 2020): The Court reiterates that “aiding and abetting is not a substantive offense” but a theory of liability. This matters because the Act targets certain felony-murder convictions “under an aiding-and-abetting theory,” and the analysis must remain focused on the conviction elements and the applicant’s mental state rather than the label used in charging or verdict forms.

Prior proceedings in the same case

  • State v. Zielinski (Zielinski I), 10 N.W.3d 1 (Minn. 2024): The Court uses its prior decision primarily as a factual and procedural anchor—explaining what was tried, argued, and instructed at the time, and emphasizing that Zielinski’s intent to cause death was not an element the State needed to prove (and therefore was not litigated). The Court is careful to note that in Zielinski I it drew no conclusions about her intent to cause death.

Appealability and the Act’s procedural architecture

  • State v. Griffin (Griffin IV), 20 N.W.3d 57 (Minn. 2025) (order): Cited for the proposition that a district court’s notice denying a preliminary application is a “final order,” confirming appellate jurisdiction over denials at the preliminary stage.
  • State v. Griffin (Griffin V), 24 N.W.3d 247 (Minn. 2025): Provides the governing abuse-of-discretion framework for denial of preliminary applications, and supplies a key comparator: Griffin’s preliminary-application allegations were contradicted by issues “considered and directly rejected” at trial/appeal, supporting denial there. In Zielinski, the Court distinguishes Griffin V because Zielinski’s intent-to-kill issue was not previously litigated or rejected.

Statutory interpretation methodology

  • Roberts v. State, 945 N.W.2d 850 (Minn. 2020): Cited for de novo review of statutory interpretation questions.
  • State v. Latino, 15 N.W.3d 654 (Minn. 2025): Emphasizes starting with statutory text and enforcing unambiguous language.
  • State v. Fugalli, 967 N.W.2d 74 (Minn. 2021): Supports the unambiguous-text approach (“only one reasonable way to read the text”).
  • State v. Moore, 10 N.W.3d 676 (Minn. 2024): Notes the use of canons of construction when ambiguity exists.
  • State v. Smith, 899 N.W.2d 120 (Minn. 2017): Central to the opinion’s “expressio unius est exclusio alterius” analysis (the expression of one thing excludes others), with a strong presumption when statutes are “uncommonly detailed and specific.” Zielinski applies Smith to treat subdivision 5(e)’s list of summary-denial grounds as exhaustive for first-time applications.

Defining technical legal terms and using legal dictionaries

  • State v. Steeprock, 28 N.W.3d 417 (Minn. 2025): Supports construing technical legal terms according to their special meaning, including reliance on legal dictionaries.
  • Fordyce v. State, 994 N.W.2d 893 (Minn. 2023): Adds that dictionary definitions must be applied “in the context of the statute.”

Appellate economy and deciding issues on the existing record

  • Herlache v. Rucks, 990 N.W.2d 443 (Minn. 2023): Cited to justify reaching the reasonable-probability issue “in the interest of judicial economy” where the record is sufficient and the parties briefed the issue.

Credibility, hearings, and limits on extra-record fact gathering

  • Andersen v. State, 913 N.W.2d 417 (Minn. 2018): Establishes that postconviction courts cannot make credibility findings without an evidentiary hearing.
  • State v. Duol, 25 N.W.3d 135 (Minn. 2025): Prohibits “independent investigations of extra-record facts.” Zielinski uses Duol to draw a boundary: the Act expressly permits consideration of “relevant records in the possession of the judicial branch,” so reviewing those records is not an impermissible independent investigation.
  • Wilson v. State, 726 N.W.2d 103 (Minn. 2007): Stands for the principle that, absent a hearing, a court cannot decide which story is true.
  • Bobo v. State, 860 N.W.2d 681 (Minn. 2015); Miles v. State, 840 N.W.2d 195 (Minn. 2013); and Hooper v. State, 838 N.W.2d 775 (Minn. 2013): Collectively underscore why credibility is best judged by the district court after live testimony—an institutional competence rationale the Court imports into Act proceedings.

2) Legal Reasoning

A. The new rule: subdivision 5(e)-(f) is exhaustive for “summary denial”

The Court’s first—and most structural—holding is a statutory constraint on district court procedure: if a court chooses the mechanism of summary denial, it may do so only for reasons the Legislature listed in subdivision 5(e)-(f). The district court here selected a form option indicating denial “based on the underlying facts,” which the Supreme Court held is not among the enumerated bases.

The Court reached this conclusion through expressio unius est exclusio alterius (as articulated in State v. Smith), reasoning that subdivision 5(e) is “very specific” and thus creates a “strong presumption” the Legislature deliberately excluded other grounds. This is not merely a stylistic preference; it enforces a separation between (i) a limited set of administrative, categorical, or preclusion-based defects that justify “summary” disposition, and (ii) merits-linked factual assessments that the Act contemplates being tested through the later petition/hearing process.

B. Defining “reasonable probability” at the preliminary stage (a forward-looking screen)

The Act requires the reviewing judge to decide whether there is a “reasonable probability” the applicant is entitled to relief. The opinion defines “reasonable probability” via Black’s Law Dictionary as “[t]he extent to which rational people might believe that a given possible outcome might materialize,” and then integrates that definition into the Act’s burden structure.

For first-degree felony murder, the ultimate entitlement standard is in subdivision 7(a): at the petition stage the petitioner must prove by a preponderance that the petitioner (1) did not cause the death, and (2) did not intentionally aid (etc.) with intent to cause death. The Court’s key move is to treat “reasonable probability” as lower than preponderance and explicitly prospective: the question is whether the applicant “might be able to prove” the subdivision 7(a) requirements at an evidentiary hearing.

In practical terms, the Court converts the preliminary application into a plausibility-like gateway: if the applicant alleges facts that could persuade a rational person that the applicant might later prove the required lack of intent-to-cause-death, the case proceeds to the petition/hearing path; the district court is not to resolve close inferences about intent at the preliminary stage.

C. No credibility determinations without an evidentiary hearing

The Court’s third holding protects the function of the evidentiary hearing required by subdivision 6. Borrowing from postconviction doctrine (Andersen v. State; Wilson v. State), the Court holds that credibility disputes— especially about subjective intent—cannot be decided on paper at the preliminary stage. It acknowledges that a judge need not accept allegations as true (Griffin V), but draws a line at using circumstantial facts to implicitly disbelieve an applicant’s stated intent where that intent was never litigated under the old felony-murder framework.

The opinion also carefully reconciles this with State v. Duol: the judge may review “relevant records in the possession of the judicial branch” because the Act expressly authorizes it, but that review is not a license to decide contested mental-state questions by discrediting the applicant without live testimony.

D. Application to Zielinski (why her preliminary allegations clear the threshold)

Zielinski alleged: (1) she did not cause Henderson’s death; (2) she did not intentionally aid her brother with intent to cause death; and (3) there was no evidence she intended death. Critically, the Court emphasizes that her trial occurred when the State did not need to prove her intent to cause death for felony-murder aiding-and-abetting liability; thus, her intent was not the subject of the adversarial process, jury instructions, or findings. Unlike in Griffin V, there was no prior proceeding “consider[ing] and directly reject[ing]” her claim.

The district court’s reasoning—planning the robbery, instructing that a gun be brought, and continuing the robbery after the shooting— may be relevant evidence at a later hearing, but the Supreme Court characterizes the district court’s use of those facts at the preliminary stage as (at least implicitly) a credibility/intent determination without a hearing, which the Act’s structure (as interpreted) does not permit.

3) Impact

A. Procedural impact: “summary denial” becomes a narrow, enumerated tool

The decision meaningfully constrains district courts’ ability to end Act proceedings at the threshold. “Summary denial” is now limited to the enumerated defects in subdivision 5(e)-(f)—missing required information, custody status, conviction/date ineligibility, irrelevance/prior appellate decision, or repeat-application scenarios. District courts cannot use “summary denial” as a shorthand vehicle for merits-based rejection “based on the underlying facts.”

This will likely shift contested cases toward the petition stage (subdivision 6) and, where intent is disputed, toward evidentiary hearings—particularly for convictions arising from trials conducted before the 2023 amendments, when the applicant’s intent-to-cause-death was not a necessary litigated element.

B. Substantive impact: a forward-looking “might be able to prove” standard for first-degree applicants

By defining “reasonable probability” as whether a rational person could believe the applicant might later prove the statutory elements, the Court lowers the risk that applicants are screened out because existing trial records (compiled under a different legal regime) fail to speak directly to the now-critical intent-to-cause-death question.

C. Institutional impact: credibility and intent questions are reserved for hearings

The explicit “no credibility determinations without an evidentiary hearing” rule will affect how district courts write orders. Courts may still consult judicial-branch records, but they must avoid resolving intent disputes at the preliminary stage by choosing among competing inferences that effectively decide credibility.

D. Likely litigation consequences

  • More petitions and hearings: Fewer preliminary terminations, more subdivision 6 proceedings.
  • Sharper focus on whether an issue was previously decided: Subdivision 5(e)(4) (prior appellate decisions) becomes a central battleground, especially in cases with prior findings that implicitly or explicitly addressed shooter identity or intent.
  • Record-development emphasis: Applicants’ testimony about intent (and corroborating evidence) becomes pivotal at the hearing stage, rather than being discounted as self-serving at the threshold.

Complex Concepts Simplified

Aiding and abetting

“Aiding and abetting” means being held responsible for a crime committed by someone else because you intentionally helped them commit it. As State v. Ezeka notes, it is not a separate crime; it is a way of proving liability for the underlying offense.

Felony murder (pre-2023) vs. post-2023 change

Under the pre-2023 rules described by the Court, a person could be convicted of certain felony murders as an accomplice even if the person did not intend anyone to die, so long as the accomplice intentionally aided the felony and a death was a foreseeable result. The 2023 Act narrowed this for first-degree felony murder “for a death caused by another” by requiring proof the accomplice acted with the intent to cause death.

Preliminary application vs. petition

The Act uses a two-step process: (1) a preliminary application asking permission to file; then, if that threshold is met, (2) a petition to vacate and (often) an evidentiary hearing. Zielinski holds the first step is a limited screening stage, not the place for final determinations about intent or credibility.

“Summary denial”

“Summary denial” means the court rejects the preliminary application immediately, without moving forward in the process. Zielinski’s key procedural rule is that “summary denial” is allowed only for the specific reasons the statute lists.

“Reasonable probability”

In this context, “reasonable probability” does not mean the applicant is more likely than not to win. It means a rational person could believe the applicant might be able to prove entitlement to relief later at a hearing (where the applicant must then meet the higher “preponderance of the evidence” burden).

Credibility determinations

A credibility determination is a decision that someone’s account is believable or not. The Court holds district courts cannot do that here without an evidentiary hearing—because evaluating credibility generally requires seeing and hearing witnesses testify.

Conclusion

State of Minnesota v. Melissa Madelyne Zielinski establishes three major guideposts for Minnesota’s 2023 aid/abet felony-murder relief process: (1) “summary denial” is confined to the Act’s enumerated grounds in subdivision 5(e)-(f); (2) “reasonable probability” for first-degree applicants is a forward-looking, rational-person “might be able to prove” standard keyed to the later preponderance burden under subdivision 7(a); and (3) credibility-based resolutions of intent are not permitted absent an evidentiary hearing under subdivision 6.

The decision therefore shifts the Act’s preliminary stage away from paper-based merits adjudication and toward its intended function as a screening mechanism, reserving disputed intent questions—especially in legacy convictions tried under broader pre-2023 liability rules—for development and resolution in evidentiary proceedings.
