A civil suit was filed Monday against a Texas doctor who revealed that he had performed an abortion on a woman more than six weeks pregnant in violation of the controversial new law restricting the procedure.

Alan Braid, in a column published in The Washington Post over the weekend, said he carried out an abortion on September 6 on a woman who was still in her first trimester but was "beyond the state's new limit," because of his "duty of care" to the patient.

The "Texas Heartbeat Act" bans abortion once a fetal heartbeat can be detected, which usually takes place at six weeks -- before many women even know they are pregnant. It makes no exceptions for rape or incest.

Braid's case could test the constitutionality of the new law in the southern US state, which took effect September 1.

The first suit against Braid was filed with a district court in Texas on Monday by a self-described "disbarred and disgraced" former lawyer in the neighboring state of Arkansas.

"I acted because I had a duty of care to this patient, as I do for all patients, and because she has a fundamental right to receive this care," Braid, who has been practicing medicine for 50 years, wrote in the Post.

The bill passed by Republican lawmakers in Texas, the country's second-largest state, allows members of the public to sue doctors who perform abortions after six weeks or anyone who facilitates the procedure.

First civil suit

The rather eccentrically worded complaint against Braid was submitted by Oscar Stilley, who is currently serving a 15-year sentence for tax fraud under home confinement.

Abortion providers and others seeking to protect a woman's right to an abortion generally file suit against state prosecutors who are seeking to enforce restrictive abortion laws.

But Texas managed to avoid close judicial scrutiny by the Supreme Court because of the way its law is framed, making it everyday people rather than prosecutors who initiate legal proceedings over abortions.

Braid's admission means that if he is prosecuted he could contest the constitutionality of the Texas law and force a court to rule on whether it violates Roe v. Wade.

The Justice Department has also filed suit against Texas, following through on a pledge by Democratic President Joe Biden to fight attempts by Republican-led states to restrict abortion.

And the Supreme Court announced on Monday that it would hear a challenge on December 1 to a Mississippi law that bans nearly all abortions after the 15th week of pregnancy.

The court ruled on the Texas law without hearing oral arguments, and the Mississippi case will be the first abortion case argued before the court since Trump named three justices to the panel, giving conservatives a 6-3 majority.
