The case of former Minneapolis police Officer Derek Chauvin continues to unfold as he seeks a new trial in his murder conviction.
According to court documents, Chauvin recently filed an appeal against a judge's decision denying his petition for post-conviction relief.
Chauvin was convicted of the murder of George Floyd in April 2021, after records showed that the former officer kneeled on Floyd's neck for nine minutes and 29 seconds while Floyd was face down and handcuffed on the ground.
This led to a fatal lack of oxygen to the brain, resulting in Floyd's death.
On June 29, Chauvin, represented by criminal defense attorney Gregory Joseph, filed an appeal of a judge's denial, made on May 1.
In the 41-page order, the judge denied Chauvin's entire post-conviction petition more than five months after it was initially filed in November 2025.
The petition's arguments include prosecutors improperly relying on video evidence, jury instructions being legally flawed and police officials giving false testimony, among others.
The judge repeatedly applied Minnesota's Knaffla rule, which generally prevents defendants from using post-conviction proceedings to raise issues that were already decided on direct appeal or could have been raised earlier but were not.
The judge concluded that essentially every one of Chauvin's claims fit into one of those two categories.
Joseph has represented Chauvin since his conviction and continued appeal efforts, and was not Chauvin's defense attorney for his initial trial.
