A statewide court declared Friday that Pennsylvania’s expansive two-year-old mail-in voting law is unconstitutional, agreeing with challenges by Republicans who soured on mail-in voting after then-President Donald Trump began attacking it as rife with fraud in 2020’s campaign. The decision, by a five-judge Commonwealth Court panel of three Republicans and two Democrats, could be put on hold immediately by an appeal from Gov. Tom Wolf’s administration to the state Supreme Court. Still, the decision throws Pennsylvania’s voting laws into doubt as the presidential battleground state’s voters prepare to elect a new governor and a new U.S. senator in 2022.
