Texas Attorney General Greg Abbott is filing an emergency appeal after a federal judge ruled the state's new abortion restrictions are unconstitutional.
Monday's ruling will block the measures that were set to go into effect Tuesday.
The law requires abortion providers to have nearby hospital admitting privileges and imposes stricter guidelines on medical abortions that take place after 20 weeks.
The judge says the law would violate the rights of abortion doctors to do what they deem best for their patients, and would "unreasonably restrict" a women's access to an abortion clinic.
But supporters of the law say it provided safety for women by holding abortion clinics to common medical standards.
"They've been operating at lower safety standards than comparable health facilities across Texas," Texas Alliance for Life's Joe Pojman said. "This law is about raising those standards at abortion facilities that any person would expect getting at comparable surgery in another facility."
The Texas attorney general said he thinks the case will eventually be decided by the U.S. Supreme Court.
