Texas Municipal Power Agency v. Public Utility Commission and City of Bryan
In this interlocutory appeal, the Texas Municipal Power Agency challenged a Public Utility Commission (PUC) order concerning the allocation of electricity transmission costs to the City of Bryan. Municipal Power Agency filed both an APA appeal and a Uniform Declaratory Judgment Act (UDJA) claim, the latter of which was dismissed by the district court on grounds of sovereign immunity and duplication of remedies. The Court of Appeals reversed this dismissal, ruling that the UDJA waives sovereign immunity when interpreting an agency's general statutory authority, even if a parallel APA appeal addressing specific agency actions is ongoing. The court emphasized that the UDJA action sought a broader declaration of the Commission's fundamental authority, distinguishing it from merely challenging a particular agency order. Therefore, the case was remanded for further proceedings on the declaratory judgment claim.
