4 attorney general’s enforcement authority to the Texas Occupational Code, and S. B. 8 is not codified within “this subtitle.” Nor have the petitioners identified for us any “rule or order adopted by the” Texas Medical Board that the attorney general might enforce against them. And even if the attorney general did have some enforcement power under S. B. 8 that could be enjoined, the petitioners have identified no authority that might allow a federal court to parlay any defendant’s enforcement authority into an injunction against any and all unnamed private parties who might seek to bring their own S.

Any individual sued under S. B. 8 may raise state and federal constitutional arguments in his or her defense without limitation. Whatever a state statute may or may not say about a defense, applicable federal constitutional defenses always stand available when properly asserted. See U. S. Const., Art. VI. Many federal constitutional rights are as a practical matter asserted typically as defenses to state-law claims, not in federal pre-enforcement cases like this one. See, e.g., Snyder v. Phelps, 562 U. S. 443 (First Amendment used as a defense to a state tort suit). Other viable avenues to contest the law’s compliance with the Federal Constitution also may be possible and the
