Minnesota Narrowed Its Felony-Murder Law - and Made It Retroactive. Here's Who It Can Help.
A 2023 Minnesota law narrowed aiding-and-abetting first-degree felony murder: the State now must prove the person intended to cause death, not just that they took part in an underlying felony. It also created a retroactive, two-step process - a preliminary application, then a petition to vacate - for people convicted under the old, broader standard to seek relief. Recent rulings show the standard is real but demanding.
What the old felony-murder rule did
Felony murder has always been one of the harshest doctrines in criminal law. Under the old aiding-and-abetting version in Minnesota, a person could be convicted of first-degree felony murder for their role in an underlying felony - like an aggravated robbery - even if they were not the one who killed anyone and did not intend for anyone to die. Participate in the felony, and a death during it could be laid at your feet as murder.
That swept broadly. Getaway drivers, lookouts, and lesser participants could end up serving life sentences for a killing they neither committed nor wanted. For years that was simply the law in Minnesota.
What the 2023 law changed
In 2023, the Legislature narrowed that doctrine. For aiding-and-abetting first-degree felony murder, the State now has to prove the defendant actually intended to cause death - not merely that they participated in the underlying felony. That is a fundamental shift in what the State must establish. The change and the review pathway were enacted by the Act of May 19, 2023, ch. 52, art. 4, sec. 24, 2023 Minn. Laws 810, 864-68.
Just as significant, the Legislature did not make the change prospective only. It created a pathway - often called the felony murder accomplice review process - for people already convicted under the old, broader standard to challenge their convictions. In other words, it reached backward to people already in prison under a rule the state no longer considers just.
The two-step path to relief
The review process has two stages, and both matter. First, a preliminary application: the person must show a reasonable probability that they are entitled to relief. A district court screens that application, and if it sees no reasonable probability of relief, it can deny it at this stage.
If the preliminary application clears that bar, the second step is a petition to vacate, where the petitioner must actually prove that they neither caused the death nor intentionally aided, advised, conspired with, or otherwise procured another with the intent to cause death. This is not automatic relief - the burden is on the petitioner, and it is a real one. The process is how the new, narrower standard gets applied to old cases.
What recent rulings show
The early case law shows both the promise and the limits. On the promise side, the Minnesota Court of Appeals has upheld the law as constitutional when applied retroactively, over objections from some prosecutors who argued it was letting people out early - and there are real people who have had life convictions vacated and been re-sentenced on lesser charges as a result.
On the limits side, relief is far from guaranteed. In Green v. State (Minn. May 13, 2026), the Minnesota Supreme Court affirmed the denial of a petition to vacate because the evidence showed the petitioner did intend to aid the killings - the new standard was not met. And in State v. Griffin, the courts had to sort out procedural questions the Act left open, like how an appeal from a denied preliminary application even works. The takeaway: the door is open, but you have to fit through it on the facts.
My read for families facing an old conviction
My read, as someone who works in this area: this is one of the more meaningful criminal-justice changes Minnesota has made in years, precisely because it reaches people who were convicted of murder without intending anyone's death. If you have a family member serving a felony-murder sentence under an aiding-and-abetting theory from before the change, it is genuinely worth having the case evaluated against the new standard.
But go in clear-eyed. The two-step process is demanding, the burden is on the petitioner at the vacatur stage, and as Green v. State shows, courts will deny relief where the record shows intent to aid a killing. Each case turns on its specific facts and record. This is my read on a developing area of Minnesota law, offered as general information and not as legal advice; anyone considering this pathway should have the conviction and the record reviewed carefully.
Questions people ask about minnesota narrowed its felony-murder law - and made it retroactive. here's who it can help.
What did Minnesota's 2023 felony-murder law change?
It narrowed aiding-and-abetting first-degree felony murder so the State must prove the defendant intended to cause death, not just that they participated in an underlying felony. It also created a retroactive process for people convicted under the old standard to seek relief.
Can an old felony-murder conviction be challenged now?
Yes, through a two-step process: a preliminary application showing a reasonable probability of relief, then a petition to vacate where the petitioner must prove they neither caused the death nor intended to aid in causing it. Relief is not automatic and the burden is on the petitioner.
Is the retroactive felony-murder law constitutional?
The Minnesota Court of Appeals has upheld the law as constitutional when applied retroactively, over objections from some prosecutors. Any specific case should be checked against current appellate decisions before relying on this pathway.
Does everyone who applies get their conviction vacated?
No. Recent cases like Green v. State show courts will deny relief where the record shows the person intended to aid the killing. The new standard is real but demanding, and each case turns on its specific facts.
