The court’s order is stunning. Presented with an application to enjoin a flagrantly unconstitutional law engineered to prohibit women from exercising their constitutional rights and evade judicial scrutiny, a majority of justices have opted to bury their heads in the sand.

Last night, the court silently acquiesced in a state’s enactment of a law that flouts nearly 50 years of federal precedents. Today, the court belatedly explains that it declined to grant relief because of procedural complexities of the state’s own invention. Because the court’s failure to act rewards tactics designed to avoid judicial review and inflicts significant harm on the applicants and on women seeking abortions in Texas, I dissent.

In May 2021, the Texas legislature enacted SB8 (the act). The act, which took effect statewide at midnight on 1 September, makes it unlawful for physicians to perform abortions if they either detect cardiac activity in an embryo or fail to perform a test to detect such activity. This equates to a near-categorical ban on abortions beginning six weeks after a woman’s last menstrual period, before many women realize they are pregnant, and months before fetal viability. According to the applicants, who are abortion providers and advocates in Texas, the act immediately prohibits care for at least 85% of Texas abortion patients and will force many abortion clinics to close.

The act is clearly unconstitutional under existing precedents. The respondents do not even try to argue otherwise. Nor could they: no federal appellate court has upheld such a comprehensive prohibition on abortions before viability under current law.

The Texas legislature was well aware of this binding precedent. To circumvent it, the legislature took the extraordinary step of enlisting private citizens to do what the state could not. The act authorizes any private citizen to file a lawsuit against any person who provides an abortion in violation of the act, “aids or abets” such an abortion (including by paying for it) regardless of whether they know the abortion is prohibited under the act, or even intends to engage in such conduct. Courts are required to enjoin the defendant from engaging in these actions in the future and to award the private-citizen plaintiff at least $10,000 in “statutory damages” for each forbidden abortion performed or aided by the defendant. In effect, the Texas legislature has deputized the state’s citizens as bounty hunters, offering them cash prizes for civilly prosecuting their neighbors’ medical procedures.

The legislature fashioned this scheme because federal constitutional challenges to state laws ordinarily are brought against state officers who are in charge of enforcing. By prohibiting state officers from enforcing the act directly and relying instead on citizen bounty hunters, the legislature sought to make it more complicated for federal courts to enjoin the act on a statewide basis.

Taken together, the act is a breathtaking act of defiance – of the constitution, of this court’s precedents, and of the rights of women seeking abortions throughout Texas. But over six weeks after the applicants filed suit to prevent the act from taking effect, a fifth circuit panel abruptly stayed all proceedings before the district court and vacated a preliminary injunction hearing that was scheduled to begin on Monday. The applicants requested emergency relief from this court, but the court said nothing. The act took effect at midnight last night.
