Officials in north Texas want a new hearing to determine whether they can buy water in southeastern Oklahoma.
The Tarrant Regional Water District late Wednesday asked a federal appeals court to reconsider their lawsuit that claims Oklahoma water laws are unconstitutional.
Earlier this month, a three-judge panel of the 10th U.S. Circuit Court of Appeals unanimously affirmed a federal judge's dismissal of the district's suit against the Oklahoma Water Resources Board.
The lawsuit, filed in 2007, argued that Oklahoma statutes governing its water rights posed burdens to interstate commerce.
The Tarrant water district serves more than 1.7 million people in 11 counties in rapidly growing north Texas.
