It looks like the ruling will be overturned,

"A statewide court on Friday declared that Pennsylvania's expansive two-year-old mail-in voting law is unconstitutional, agreeing with challenges by Republicans.
The decision, by a five-judge Commonwealth Court panel of three Republicans and two Democrats, would be put on hold immediately if Gov. Tom Wolf's administration files an appeal to the state Supreme Court as promised.
"The Administration will immediately appeal this decision to the state Supreme Court and today’s lower court ruling will have no immediate effect on mail-in voting pending a final decision on the appeal," Wolf's office said in a statement."
