Monday's decision came after the comedian's lawyers asked for outside jurors because of ongoing publicity. They suggested a large, diverse jury pool from either Philadelphia or the Pittsburgh area.
WPXI legal analyst Phil DiLucente said he expects jury selection will take several weeks due to the complexities of the case.
"It's the other side of the state, but it has the great cross section of society. You're also looking for balance. You want balance when it comes to ethnicity. You want balance when it comes to occupations," DiLucente said.
A spokeswoman for the Montgomery County district's attorney's office said the trial is expected to take more than a week, with legal experts saying it could go much longer than that. The trial is set to start by early June, and the jury will be sequestered.
"The hardships (for jurors) are going to be numerous, whether it's occupational, familial; whether it's medical. Those are all going to be taken into consideration," DiLucente said.
Defense lawyer Brian McMonagle said he had no comment Monday on the decision from the state Supreme Court. It was not clear as of Tuesday when jury selection will start in Allegheny County.
