U.S. District Judge Vince Chhabria of the Northern District of California.

A federal judge declined Wednesday to force the Trump administration to make critical payments to health insurers under the Affordable Care Act, finding that although the law requires insurance companies be paid, it's unclear whether Congress has actually set aside money for these payments.

U.S. District Judge Vince Chhabria of the Northern District of California, appointed by President Barack Obama, said in his order that the requirements for a preliminary injunction forcing the government to pay up were not met because the Trump administration made more convincing legal arguments that the payments were not appropriated by Congress. A group of 17 Democratic attorneys general, including California's Xavier Becerra and New York's Eric Schneiderman, sued the Trump administration Oct. 13 to force the government to continue the payments. But Chhabria found that forcing the administration to make the payments would be “counterproductive” thanks to steps the states had made in anticipation of Trump's move to cut off the subsidies.

“State regulators have been working for months to prepare for the termination of these payments,” Chhabria wrote. “And although you wouldn't know it from reading the states' papers in this lawsuit, the truth is that most state regulators have devised responses that give millions of lower-income people better health coverage options than they would otherwise have had.”
