City of Corpus Christi, Appellants v. Public Utility Commission of Texas, Appellees

Summary

The Texas Supreme Court affirmed the trial court's denial of an injunction against the Public Utility Commission's final rate order, holding that it has direct‑appeal jurisdiction over the cities' challenges, that Section 23 of the Public Utility Regulatory Act places the burden of separating data on the municipalities, and that the interim order is moot. Justice Daniel dissented, arguing that the Commission should not rely on system‑wide data and that municipalities retain original rate‑making authority.
