TEXAS MUN. POWER AGEN. v. Pub. Util. Com'n
Texas Municipal Power Agency (Municipal Power) challenged an order by the Public Utility Commission (Commission) concerning the allocation of electricity transmission costs to the City of Bryan. Municipal Power filed an Administrative Procedure Act (APA) appeal and later amended its petition to include a declaratory judgment action under the Uniform Declaratory Judgment Act (UDJA), seeking a declaration on the scope of the Commission's statutory authority under the Public Utility Regulatory Act (PURA). The trial court granted pleas to the jurisdiction, dismissing the UDJA action on grounds of sovereign immunity and duplication of remedies available in the APA appeal. The Court of Appeals reversed, holding that the UDJA waives sovereign immunity for claims seeking an interpretation of an agency's general statutory authority and that the UDJA action was distinct from and broader than the APA appeal, which only addressed specific agency orders.
