The Pennsylvania Supreme Court on Wednesday declined to take up Bill Cosby's appeal challenging a judge's decision earlier this year to spare his accuser from testifying until his sexual assault trial in June.

Cosby had argued that Andrea Constand's failure to testify at a preliminary evidentiary hearing in May 2016 violated his due process rights and denied him the opportunity to confront her in court before the case lands in front of a jury.

Instead, Montgomery County Common Pleas Judge Steven T. O'Neill allowed the case to move forward based on police statements Constand gave more than a decade ago about the alleged assault and testimony from the investigators who interviewed her at the time.

Cosby stands accused of drugging and assaulting Constand, a former Temple University employee, during a 2004 visit to his Cheltenham mansion. Jury selection in the case is scheduled to begin in Pittsburgh next month.
