A judge held a hearing Tuesday but didn’t say how she would decide a lawsuit filed by Mississippi’s only abortion clinic, which is trying to remain open by blocking a law that would ban most abortions in the state.

The law — which state lawmakers passed before the U.S. Supreme Court overturned the 1973 ruling that allowed abortions nationwide — is set to take effect Thursday.

The Jackson Women’s Health Organization sought a temporary restraining order that would allow it to remain open, at least while the lawsuit remains in court.

The closely watched lawsuit is part of a flurry of activity that has occurred nationwide since the Supreme Court ruled. Conservative states have moved to halt or limit abortions while others have sought to ensure abortion rights, all as some women try to obtain the medical procedure against the changing legal landscape.

Meanwhile a Florida judge on Tuesday temporarily blocked a new 15-week abortion ban days after it took effect in the state, an expected move following an oral ruling last week in which he said the law violated the state constitution.
