Conrad Murray signed a one-page document that was filed in Los Angeles on Friday seeking all records and transcripts from the case. The filing does not indicate the basis on which Murray will argue to overturn his conviction or sentence.
The 58-year-old was sentenced Tuesday to four years in jail for his involuntary manslaughter conviction, but the term will be automatically cut in half.
Murray's challenge will be heard by a state appeals court in Los Angeles, assuming he files an opening brief at a later date.
Superior Court Judge Michael Pastor blasted Murray's conduct on Tuesday, calling him a disgrace to the medical profession.
