UNDATED (AP) – Comedian Bill Cosby is appealing a court decision last month that upheld his conviction for drugging and sexually assaulting a woman in 2004. The brief filed Thursday with the Pennsylvania Supreme Court focuses on four key trial issues. They include the judge’s decision to let five other accusers testify and to send Cosby to trial despite a prosecutor’s earlier promise not to charge him. The 82-year-old Cosby is serving a three- to 10-year prison term at a maximum-security state prison near Philadelphia. He calls the encounter consensual. But a jury in April 2018 convicted him on all three felony counts in the first celebrity trial of the #MeToo era.
