A pregnant Texas woman whose fetus has a fatal condition sued the state on Tuesday seeking an emergency court order to allow her doctor to perform an abortion, despite the state’s strict bans on the procedure.

The lawsuit is believed to be one of the first attempts in the nation to seek a court-ordered abortion since the Supreme Court overturned Roe v. Wade last year, allowing states to make their own abortion laws.

Texas is at the forefront of states that restrict abortion, and has overlapping bans that outlaw abortions from the point of fertilization and allow private citizens to sue others who might help a woman obtain an abortion. The laws allow some exceptions to save the health and life of the pregnant woman, though abortion rights advocates argue that they are unclear, putting women with pregnancy complications at risk.

The vagueness of the exceptions in Texas have prevented doctors from performing the procedure in most cases, lawyers for the woman, Kate Cox, have argued. A decision in her case could force the state to more clearly define what is allowed under the law.
