2 Opinion of the Court 24-10327 Appeal from the United States District Court for the Northern District of Georgia D.C. Docket No. 1:23-cv-01834-ELR ____________________ Before WILLIAM PRYOR, Chief Judge, and LUCK and BRASHER, Cir- cuit Judges.

WILLIAM PRYOR, Chief Judge: This appeal requires us to decide whether a district court erred when it dismissed a lawyer’s complaint against a state bar foundation, a state bar office of the general counsel, and an assis- tant general counsel on the ground that the state supreme court has exclusive jurisdiction over attorney misconduct. When the State Bar of Georgia prosecuted Marsha Mignott for misconduct, she filed this putative class action in response and alleged that her prosecution was racially discriminatory. See 42 U.S.C. § 1981. The district court dismissed Mignott’s complaint on the ground that the Supreme Court of Georgia has exclusive jurisdiction over attorney misconduct proceedings. Because federal, not state, law governs the subject-matter jurisdiction of the district court, we vacate and remand for further proceedings.

I. BACKGROUND Marsha Williams Mignott is an attorney licensed to practice law in the State of Georgia. In re Mignott, 893 S.E.2d 891, 891 (Ga. 2023). A prospective client filed a grievance against Mignott with the State Bar of Georgia. Id. A special master concluded that USCA11 Case: 24-10327 Document: 46-1 Date Filed: 07/30/2025 Page: 3 of 6

24-10327 Opinion of the Court 3 Mignott violated two rules of professional conduct and recom- mended that she receive a two-year suspension. Id. at 892.

While the disciplinary proceeding was ongoing, Mignott filed this putative class action. She alleged that the State Bar of Georgia Foundation, Inc., the State Bar of Georgia Office of the General Counsel, and William Van Hearnburg Jr., in his official ca- pacity as Assistant General Counsel for the State Bar of Georgia, discriminated against her and other black attorneys by pursuing “fraudulent grievances” against them and by subjecting them “to unequal grievance and disciplinary proceedings relative to their white peers.” See 42 U.S.C. § 1981. Mignott sought declaratory and injunctive relief and damages.

The State Disciplinary Review Board adopted the special master’s findings but recommended that she receive a one-year suspension. In re Mignott, 893 S.E.2d at 892. Upon review, the Su- preme Court of Georgia ruled that Mignott did not violate any rule of professional conduct because she “never formed an attorney-cli- ent relationship with the grievant” and the rules of conduct that Mignott was charged with violating “do not apply to prospective clients.” Mignott, 893 S.E.2d at 892. So it “impose[d] no discipline and dismiss[ed] th[e] matter.” Id. It also later denied the State Bar’s motion for reconsideration.

Meanwhile, after the defendants moved to dismiss Mignott’s federal complaint on several grounds, the district court dismissed for lack of subject-matter jurisdiction. It explained that “[t]he Su- preme Court of Georgia is endowed with the inherent and USCA11 Case: 24-10327 Document: 46-1 Date Filed: 07/30/2025 Page: 4 of 6

4 Opinion of the Court 24-10327 exclusive authority to govern the practice of law in Georgia,” and it relied on Wallace v. State Bar of Ga., 486 S.E.2d 165, 166 (Ga. 1997), as authority for that proposition. It ruled that Mignott’s complaint “necessarily implicates and challenges ‘the action or inaction of the State Bar or any person in connection with a disciplinary proceed- ing’ such that [it] lack[ed] subject matter jurisdiction over this case.” See id. II. STANDARD OF REVIEW We review de novo our subject-matter jurisdiction. Uberoi v. Sup. Ct. of Fla., 819 F.3d 1311, 1313 (11th Cir. 2016).

III. DISCUSSION The district court erred in ruling that state law defined its subject-matter jurisdiction. A district court has “original jurisdic- tion of all civil actions arising under the Constitution, laws, or trea- ties of the United States.” 28 U.S.C. § 1331. “[A] case arises under federal law when federal law creates the cause of action asserted.”

Gunn v. Minton, 568 U.S. 251, 257 (2013). State law cannot strip a federal court of jurisdiction that federal law otherwise provides. See U.S. CONST. art. VI, cl. 2 (“This Constitution, and the Laws of the United States which shall be made in Pursuance thereof . . . shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.”). Mignott’s complaint arises under federal law, which supplies her cause of action. See 42 U.S.C. § 1981. And Georgia law cannot divest the district court of federal-question jurisdiction. Indeed, inferior courts “must . . .

24-10327 Opinion of the Court 5 determine their jurisdiction and powers without regard to state law.” BRYAN A. GARNER ET AL., THE LAW OF JUDICIAL PRECEDENT § 65, at 556 (2016).

The Rooker-Feldman doctrine, see Rooker v. Fid. Tr. Co., 263 U.S. 413 (1923); D.C. Court of Appeals v. Feldman, 460 U.S. 462 (1983), also cannot support the dismissal of Mignott’s complaint. That doc- trine bars “cases brought by state-court losers complaining of inju- ries caused by state-court judgments rendered before the district court proceedings commenced and inviting district court review and rejection of those judgments.” Behr v. Campbell, 8 F.4th 1206, 1212 (11th Cir. 2021) (citation and internal quotation marks omit- ted). “Its application is narrow and . . . quite simple.” Id. Mignott does not seek to “modify or overturn an injurious state-court judg- ment.” Id. at 1210. Indeed, she prevailed in the Supreme Court of Georgia, which held that she did not violate any rule of professional conduct. Mignott is not a “state-court loser[] complaining of inju- ries caused by [a] state-court judgment[].” Id. at 1212.

We express no opinion on whether Mignott’s complaint suf- fers from other jurisdictional defects or states a plausible claim for relief. Nor do we express any view about whether any defendant enjoys immunity from suit or any remedy. “[W]e decline to reach” the alternative grounds for dismissal because they “are better suited for the district court to consider first on remand with the benefit of . . . thorough briefing.” Muscogee (Creek) Nation v. Rollin, 119 F.4th 881, 892 (11th Cir. 2024).
