§ 764.070.Judgment Not Binding Or Conclusive Upon State Or United States Unless Joined

Sovereign parties get special protection from the general binding effect § 764.030 gives quiet title judgments. Regardless of anything else this chapter provides, a judgment doesn't bind or conclusively affect the state unless the state was individually joined as a party — the same principle § 762.090 anticipates by allowing that joinder.

The United States gets an even stronger protection. A quiet title judgment doesn't bind the United States unless it was individually joined as a party and federal law authorizes a judgment in the action to bind its interests. Joinder alone isn't enough for the federal government; the underlying federal law also has to permit it.
