Pennsylvania’s high court on Thursday overturned the use of automatic life sentences without parole for people convicted of second-degree murder, saying it violates the state’s constitutional ban on cruel punishment when imposed without a closer look at the defendant’s specific role and culpability.

The court majority ordered resentencing in the case of Derek Lee, convicted of a 2014 killing in Pittsburgh, but the decision also has implications for others among the roughly 1,000 other inmates currently serving similar second-degree murder sentences.

The court’s order was put on hold for four months to give the General Assembly time to “consider appropriate remedial measures.” In a footnote, the justices said they were ruling on Lee’s sentence and not addressing “questions of retroactivity.”

Prison reform groups hailed it as a landmark decision, while the Allegheny County district attorney’s office said it will follow the court’s order.

Pennsylvania law has made people liable for second-degree murder if they participated in an eligible felony that led to death, and life without parole has been the only possible sentence.

“The mandatory penalty scheme of life without parole for all offenders convicted of second degree murder fails to assess individual culpability regarding the intent to kill, and mandates the same punishment regardless of that culpability,” wrote Chief Justice Debra Todd in the lead opinion. She characterized it as not distinguishing “between the lookout, and the killer who pulls the trigger.”

The state high court’s decision comes after years of advocacy to undo mandatory life without parole sentences both in Pennsylvania and nationally. Nazgol Ghandnoosh of the Washington-based Sentencing Project said she counts 11 states and the federal system as having such laws for that kind of crime, sometimes called felony murder. Several states — California, Colorado and Minnesota — have moved away from that sentencing framework in recent years, she said.

Justice Kevin Dougherty noted in a separate opinion that unlike those convicted of first-degree murder, defendants serving life without parole for second-degree murder have “never been found by a judge or jury to have harbored the specific intent to kill” and may not have had “any involvement whatsoever with the actual killing. He or she does not even have to expect or foresee that a life may be taken.”

Lee’s lawyers had wanted the court to rule that life without parole sentences are unconstitutional for all second-degree murder convictions in Pennsylvania, said Quinn Cozzens, a staff attorney for the Abolitionist Law Center, which helped represent Lee. Instead, the court ruled that trial judges must examine the individual circumstances of a defendant’s case to decide which sentence is most appropriate, including the potential of life without parole.

The state’s public defenders’ association said the ruling will generate new post-conviction litigation and require them to do more investigation as well as develop “strategic litigation” to get the decision to apply retroactively.

A jury convicted Lee of second-degree murder but acquitted him of first-degree murder in 44-year-old Leonard Butler’s shooting death. Butler was shot in a struggle over a gun with Lee’s codefendant, Paul Durham.

Prosecutors argued it should be up to state lawmakers and the executive branch to address the policy issues surrounding second-degree murder sentences. Todd wrote that while the district attorney’s office “acknowledges that there may be persuasive arguments why a non-slayer should not be held to the same degree of culpability as the slayer, it stresses that these are policy decisions for the General Assembly.”

Cozzens urged lawmakers to “address this constitutional violation, given that the court granted them the opportunity to do so.”

Rep. Tim Briggs, a suburban Philadelphia Democrat who chairs the state House Judiciary Committee, said he planned to engage with Senate Republicans on potential legislation in response.

Briggs said he wanted to have decision apply retroactively, to give people serving life “for being the getaway driver” to “have the opportunity to have their facts looked at again.”

“I think inaction leaves a lot of this up to the courts to decide. I don’t feel comfortable doing that,” Briggs said. “We have a policymaking role here.”

Justice Sallie Mundy wrote that Lee “willingly participated in an armed home invasion and robbery, and purposefully engaged in assaultive behavior in the form of tasing and pistol-whipping the victim.” She said Lee and Durham “arguably kidnapped the victims by forcing them into the basement” and it will be up to the county judge to decide if Lee’s life-without-parole sentence is appropriate.

Todd’s opinion, citing an advocacy group, said 73% of those convicted of felony murder in Pennsylvania were 25 or younger when the killing occurred and almost 70% are Black people.

Pennsylvania Governor Josh Shapiro also responded to the ruling on X.

Today, Pennsylvania’s Supreme Court ruled that mandatory life sentences without the possibility of parole for second degree murder are unconstitutional.

I have long believed this law is unjust and wrong. As Governor, I took legal action in this case arguing to strike down this…
