AUSTIN, Texas (AP) — The Texas Supreme Court on Friday rejected a challenge to one of the most restrictive abortion bans in the U.S. following a lawsuit by women who had serious pregnancy complications.

The ruling from the court, whose nine justices are all elected Republicans, is the latest decision to uphold Texas’ abortion ban, which critics say does not offer enough clarity over when exceptions are allowed.

Last summer, state District Judge Jessica Mangrum had granted a temporary injunction preventing Texas from enforcing the ban against doctors who in their “good faith judgment” ended a pregnancy that they determined was unsafe because of complications. But that was immediately blocked by an appeal from the Texas attorney general’s office to the state’s Supreme Court.
