Engelman Irrigation District v. Shields Brothers, Inc.

Summary

The Texas Supreme Court affirmed the Court of Appeals judgment, holding that the Engelman I judgment is not void and cannot be attacked collaterally despite the later Tooke decision. The Court declined to apply Tooke retroactively to final judgments and clarified that sovereign immunity does not equate to a lack of subject‑matter jurisdiction for purposes of overturning a final judgment. The decision rests on res judicata principles and the modern Restatement approach to finality.
