Bill Cosby has lost his latest effort to have criminal sex-assault charges thrown out on appeal in Montgomery County.

Cosby's lawyers argue that accuser Andrea Constand should have testified at a preliminary hearing so they could confront his accuser.

Pennsylvania law allows prosecutors to use hearsay testimony from police at pretrial hearings, and the state Superior Court on Wednesday denied Cosby's appeal.

But defense lawyer Brian McMonagle said he hopes to join a related appeal being heard by the state Supreme Court.

Cosby is set for trial in June on charges he drugged and molested Constand at his home in Cheltenham Township in 2004. He has pleaded not guilty.
