The Pennsylvania Supreme Court said Friday it will again consider whether voters should have to write the correct date on return envelopes for mail ballots to be counted.

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.

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.
