Mohamed Noor,who is serving a 12.5 year prison sentence after a Minneapolis jury found him guilty a year ago of third-degree murder and second-degree manslaughter,filed an appeal on Friday.
The 34-year-old is requesting a new trial.
"Noor's prosecution was a sordid series of events that debased the criminal justice system,"Noor's legal team wrote in a 69-page appellant's brief filed in the Minnesota Court of Appeals.
"Noor's convictions must be reversed and his case remanded for a new trial."
Damond's tragic death and Noor's conviction created global headlines.
