Former Bolingbrook Police Sergeant Drew Peterson is expected to formally appeal his conviction next month.
Peterson’s attorneys have submitted several requests to file longer briefs than allowed, but the court has denied those requests so far.
Attorneys argue that the extra length is necessary because Peterson’s murder trial generated too much material to respond to.
Peterson was convicted last year of killing his third wife, Kathleen Savio.
He was sentenced to 38-years in prison in February.
Peterson’s appeal must be filed by January 14.
