Making their way before the state Supreme Court on expedited review, two lawsuits challenging Pennsylvania’s mandatory judicial retirement age headline an oral argument session in Harrisburg scheduled to begin today.

The judges’ challenges were dispatched to the high court in March in a somewhat unusual order directing expedited briefing on the constitutionality of the retirement age and will go before the court Wednesday, the busier day of the two-day session. As it stands, the law requires that Pennsylvania judges retire in the year they turn 70.
