Disgraced TV icon Bill Cosby, who could face 10 years in prison if found guilty of three felony charges of second-degree aggravated indecent assault in a Pennsylvania case, is making a renewed effort to have the case thrown out of court, Deadline.com reports.

Cosby has a new lead attorney, Angela Agrusa, who along with Brian McMonagle filed a motion to dismiss the charges, which stem from an alleged rape in 2004. Cosby has a trial scheduled to begin as early as June 5.

The new motion “recounts how the Montgomery County DA’s office pledged not to prosecute Cosby in 2005 after a lengthy investigation of claims made by former Temple basketball coach Andrea Constand that he had assaulted her at his home,” Deadline reports. “The lawyers say it’s the first of several new pleadings expected in coming weeks challenging both the criminal and civil cases against him.”

The report quotes Cosby’s legal team, citing precedent from the Pennsylvania Supreme Court, saying: “When a defendant is prejudiced by the government’s delay in bringing charges, ‘the absence of valid reasons to justify the late filing of charges will mandate the trial court’ to dismiss those charges.”
