Background
Lisa Jo Chamberlin was convicted in 2006 of two counts of capital murder and sentenced to death. The Mississippi Supreme Court affirmed her convictions and sentences on direct appeal and later denied two petitions for post-conviction collateral relief.
In her third petition, Chamberlin argued that the State violated the Fourteenth Amendment’s Due Process Clause by introducing irrelevant and prejudicial testimony about her sexual conduct and perceived failings as a mother. She contended that the U.S. Supreme Court’s 2025 decision in Andrew v. White was an intervening decision that allowed her claim to proceed despite Mississippi’s statutory procedural bars. The State moved to dismiss.
The Court’s Holding
The Mississippi Supreme Court granted the State’s motion and dismissed Chamberlin’s petition. The Court held that her claim was barred by the one-year limitations period, the prohibition against successive petitions, waiver, and res judicata. It concluded that Andrew did not satisfy the intervening-decision exception because Chamberlin had not shown that the decision would actually have adversely affected the outcome of her conviction or sentence.
The Court also ruled in the alternative that Chamberlin’s claim failed to make the substantial showing of a denial of a state or federal right required for post-conviction relief. Presiding Justice King objected separately, reasoning that heightened scrutiny in death-penalty cases warranted an evidentiary hearing concerning Chamberlin’s sentence, though not the guilt phase.
Key Takeaways
- A new U.S. Supreme Court decision does not overcome Mississippi’s post-conviction procedural bars unless it would actually have adversely affected the petitioner’s conviction or sentence.
- Chamberlin’s third petition was untimely and successive, and her claim also implicated waiver and res judicata.
- The Court alternatively found no substantial showing that the challenged evidence denied Chamberlin a state or federal right.
- Justice King would have allowed a sentencing-phase evidentiary hearing based on Andrew, heightened scrutiny, and the cumulative evidence Chamberlin presented.
Why It Matters
The order applies Mississippi’s procedural limits strictly even in a capital case and illustrates the demanding showing required to invoke the intervening-decision exception. A petitioner must establish more than a similarity between a new precedent and the evidence challenged in the petitioner’s trial.
The separate objection highlights a competing approach to capital post-conviction review: resolving doubts in favor of allowing further examination when allegedly irrelevant, gender-based evidence may have influenced the jury’s decision to impose death.
