A federal judge on Tuesday temporarily blocked Texas from cutting off Medicaid funding to Planned Parenthood, ruling the state had presented no credible evidence to support claims the organization violated medical or ethical standards related to abortion procedures.

The ruling, a preliminary injunction issued by Sam Sparks, a United States District Court judge in the Western District of Texas, means that, for now, 30 health centers that serve about 12,500 Medicaid patients can continue to receive funding from the medical program that serves the poor. The case is set to go to trial, where the judge can rule on its merits.

The state’s attorney general, Ken Paxton, said in a statement on Tuesday that Texas would appeal the injunction.

Cecile Richards, the president of the Planned Parenthood Action Fund, hailed the ruling, calling it a “victory for Texas women.” In a statement, she said, “We will never back down, and we will never stop fighting for our patients.”
