A new post-conviction relief petition challenges Derek Chauvin’s murder conviction with allegations of prosecutorial misconduct and false testimony that could potentially overturn one of the most high-profile police convictions in American history.
Story Highlights
- Attorney Greg Joseph files substantive post-conviction relief petition in Minnesota appellate courts
- Petition alleges prosecutorial misconduct and false testimony from Minneapolis Police Department officials
- Medical Examiner Andrew Baker’s early assessment showed no evidence of homicide, according to prosecutors’ own documents
- Challenge differs from previous appeals by focusing on specific misconduct rather than procedural issues
New Legal Challenge Emerges After Years of Failed Appeals
Attorney Greg Joseph has filed a post-conviction relief petition in Minnesota appellate courts that legal observers characterize as the first serious challenge to Derek Chauvin’s conviction since his April 2021 murder trial. The petition alleges grave judicial and prosecutorial abuses during the original proceedings that convicted Chauvin of second-degree unintentional murder, third-degree murder, and second-degree manslaughter in George Floyd’s death. This development comes after four years of unsuccessful appeals through Minnesota courts and the U.S. Supreme Court, which declined to hear Chauvin’s case in November 2023.

Prosecutorial Misconduct Allegations Challenge Trial Integrity
The petition specifically targets what Joseph describes as abusive prosecutorial conduct and the presentation of misleading testimony during Chauvin’s trial. Central to these allegations is Medical Examiner Andrew Baker, whose early assessment documented in prosecutors’ own memoranda reportedly showed Floyd had no evidence of homicide and no lethal injuries. The petition builds on prior work by attorney Chris Madel, who exposed alleged false testimony from Minneapolis Police Department officials regarding restraint techniques used on Floyd during the May 2020 arrest.
False Testimony Claims Target Police Department Officials
Joseph’s petition alleges that sworn testimony from Minneapolis Police Department officials contained false information about the restraint technique used on Floyd. These allegations suggest institutional coordination that may have influenced trial testimony, potentially undermining the foundation of the prosecution’s case. The petition references a separate case where Judge Wahl dismissed charges with prejudice, required acknowledgment of inaccurate statements, and ordered payment of defendants’ legal fees, which Joseph argues reinforces claims that questionable testimony should not have been relied upon during Chauvin’s trial.
Constitutional Concerns and Broader Implications
The petition raises concerns about violations of the officers’ civil rights and constitutional protections, arguing that the original trial created what Joseph characterizes as a “target-rich environment” for appellate challenge. If successful, the petition could not only result in vacating Chauvin’s conviction and obtaining a new trial, but could also affect the convictions of the other three officers involved in Floyd’s death. This represents a significant shift from earlier appeals that focused on venue and pre-trial publicity issues rather than substantive allegations of misconduct and false testimony.
The case continues to occupy a significant place in national conversations about police accountability and prosecutorial standards. Conservative legal observers view this petition as substantively different from and stronger than previous appeals, emphasizing the documented evidence from prosecutors’ own files and specific factual allegations rather than procedural arguments that failed in earlier challenges.
