State courts typically accord CSC appeals preclusive effect pursuant to res judicata, with a narrow exception for Article 78 review. See New York City Dep't of Envtl. Prot. v. New York City Civil Serv. Comm'n, 579 N.E.2d 1385, 1386 (Ny. Ct. App. 1991) (affirming judgment of the Appellate Division First Department according a CSC determination preclusive effect where the state court did not find that the determination was illegal, unconstitutional or outside the CSC's jurisdiction); Agbai v. New York City Civil Serv. Comm'n, 150 A.D.3d 443, (N.Y. App. Div. May 9, 2017). It is firmly established that where state courts would accord a decision preclusive effect, federal courts should do the same.
