The Pennsylvania Supreme Court threw out a lower court ruling that required such ballots to be counted during November’s presidential election.

The Pennsylvania Supreme Court ruled that mail ballots that are improperly dated won't be counted in November, a move that could have major implications in the battleground state.

Pennsylvania voters could have their mail-in ballots thrown out if they do not write accurate dates on envelopes they use to return them under a state Supreme Court ruling issued Friday that could impact the presidential race.
