Missouri Pub. Serv. Comm’n v. Office of Pub. CounselAnnotate this Case
Liberty Energy (Midstates) Corp. (Liberty), a public utility and a gas corporation, requested an increase to its Infrastructure System Replacement Surcharge (ISRS). After an evidentiary hearing, the Missouri Public Service Commission (PSC) approved the ISRS increase for Liberty. Accordingly, Liberty filed new ISRS tariffs in compliance with the PSC’s order, and the PSC approved the tariffs. The Office of Public Counsel, which is appointed by the director of the department of economic development and may represent the public interest in appeals from the PSC’s orders, appealed. The Supreme Court reversed, holding that the PSC failed to follow the plain language of its statutory mandates, and therefore, its order was unlawful. Remanded.
