NORRISTOWN, Pa. (CBS) — Bill Cosby will be back in a Montgomery County courtroom Thursday afternoon for another pretrial hearing, as the 78-year-old comedian battles charges he drugged and raped a woman at his Cheltenham mansion twelve years ago.

Cosby’s attorneys argue the entertainer’s due-process rights were violated when he was unable to confront his accuser, Andrea Constand, at his preliminary hearing in May.

They contend he should be given a new hearing and Constand should be forced to take the stand.

Cosby was ordered to stand trial at that hearing as Constand’s statements to police from 2005 were presented as evidence.

Prosecutors say the defense wants to attack the credibility of Cosby’s accuser, but they argue credibility is not an issue for a preliminary hearing, saying instead the defense will have that chance at the trial.

Cosby is charged with giving Constand pills at his Cheltenham mansion in 2004, and then molesting her while she was incapacitated.
