A U.S. district judge on Friday blocked Mississippi’s restrictive abortion law, setting the stage for more court battles as conservative lawmakers continue to challenge Roe v. Wade.

U.S. District Judge Carlton Reeves heard arguments on Tuesday over a request from Mississippi’s only remaining abortion clinic to prevent the law from going into effect on July 1.

The clinic, Jackson Women’s Health Organization, filed a lawsuit to block the law, which bans women from obtaining an abortion once a fetal heartbeat is detected.

Reeves previously struck down a law Mississippi enacted banning abortions after 15 weeks, writing in November that it “unequivocally” violated women’s constitutional rights.

The new law, which Republican Gov. Phil Bryant signed in March, states that physicians who perform abortions after a fetal heartbeat is detected may have their state medical licenses revoked. It permits exceptions only if the woman’s life is endangered by the pregnancy, and it does not include exceptions for pregnancies caused by rape or incest.

Bryant tweeted Sunday that “a new national movement has begun.”
