Texas Attorney General Ken Paxton is urging an appeals court to stop the federal government from enforcing a provision of a $1.7 trillion government spending bill, arguing that the House violated the U.S. Constitution when it relied on proxy voting to pass the measure in 2022.

Paxton wrote in a brief filed Wednesday night that the U.S. 5th Circuit Court of Appeals should affirm a lower court’s decision that a quorum was not present for the bill’s passage.
