TULSA, Oklahoma -- The League of Women Voters has sued to stop enforcement of a recently approved constitutional amendment that would require Oklahoma voters to prove their identity before voting.
The "Voter ID" ballot question was approved by 74 percent of Oklahoma voters two weeks ago. Tuesday's challenge was filed in Tulsa and is the third one filed against measures passed on Nov. 2.
Prior to the election, the League of Women Voters complained the Voter ID measure would raise "a new barrier" for the elderly, the poor and minorities.
Under the provisions of the voter ID measure, scheduled to take effect July 1, voters would have to present a valid photo identification card from the state, tribal or federal government, though the elderly could use photo IDs without an expiration date.
Those without a proper identification card could sign a sworn statement but would only be allowed to cast a provisional ballot.
Tuesday's lawsuit is the third legal challenge of a ballot measure approved this month by voters. The others measures being challenged require that the English language be used in most government business and bar the use of international law when settling court disputes.
