The Texas Supreme Court on Friday night put on hold a judge’s ruling that approved an abortion for a pregnant woman whose fetus has a fatal diagnosis, throwing into limbo an unprecedented challenge to one of the most restrictive bans in the U.S.

The order by the all-Republican court came more than 30 hours after Kate Cox, a 31-year-old mother of two from the Dallas area, received a temporary restraining order from a lower court judge that prevents Texas from enforcing the state’s ban in her case.

In a one-page order, the court said it was temporarily staying Thursday’s ruling “without regard to the merits.” The case is still pending.
