A federal judge decided Monday to stop Texas from denying Planned Parenthood state funds, saying there's evidence the law is unconstitutional.
U.S. District Judge Lee Yeakel issued an injunction against enforcing the law until he can hear full arguments. The state has already filed an appeal against the decision.
"The court is particularly influenced by the potential for immediate loss of access to necessary medical services by several thousand Texas women," Yeakel said in his ruling.
He added that the "continued viability" of the states Women's Health Program would be uncertain.
Last year, Texas passed the law banning state agencies from funding organizations affiliated with abortion providers. Eight Texas Planned Parenthood clinics filed a lawsuit as a result.
Texas law already required that groups receiving federal or state funding be legally and financially separate from abortion clinics.
