The Supreme Court will now decide whether the Pennsylvania Commonwealth Court made the right decision in November when it ruled Philadelphia had violated voters rights by rejecting undated ballots in its special election. That ruling, which came days before the November election, was blocked from taking effect in the critical election.

The Pennsylvania Supreme Court will again consider whether voters should have to write the accurate date by hand on return envelopes used to send their completed mail-in ballots to be counted.

Justices said Friday they will decide whether the dating rule for absentee and mail ballot return envelopes violates a state constitutional provision that elections must be free and equal.
