Chauvin submitted the filing last month in Hennepin County District Court. In the filing, Chauvin claims his conviction should be vacated, saying flawed medical testimony, misrepresented police training and faulty jury instructions warrant a new trial or evidentiary hearing.
Chauvin disputes the conclusions of four physicians who reviewed a medical examiner’s report on Floyd’s death, insisting they relied on video evidence of Minneapolis police officers restraining Floyd.
"This led to many errors throughout, as improperly qualified experts opined on events in the various videos in this case," the filing reads. "This served to deprive Chauvin of his right to due process."
The filing states that Chauvin retained physicians at the Forensic Panel who will testify that the physicians who testified at his trial used methodology that "is not generally accepted in the scientific community."
Chauvin also disputed testimony from three Minneapolis police supervisors, who swore the tactic of placing a knee on a suspect’s neck as a restraint was inconsistent with city police policy.
The filing states that 34 current and former Minneapolis police officers have made sworn statements saying the knee tactic was part of their training and consistent with the department’s policy.
