State ex rel. MoGas Pipeline, LLC v. Pub. Serv. Comm'nAnnotate this Case
MoGas Pipeline operated an interstate natural gas pipeline delivering natural gas to customers in Missouri. MoGas submitted to the Federal Energy Regulatory Commission (FERC) two proposals for approval. In both instances, the Missouri Public Service Commission (PSC) intervened as a party in the related FERC proceedings and to protest MoGas' proposals. MoGas subsequently filed a petition with the PSC alleging that the PSC did not have authority to intervene in matters before the FERC and requesting that the PSC terminate its intervention in FERC cases concerning MoGas' operations. The PSC denied MoGas' petition. The circuit court reversed, concluding that the PSC's order was unlawful. The Supreme Court affirmed as modified, holding that the PSC has no authority to intervene in matters pending before the FERC, and accordingly, the PSC erred in denying MoGas' request that it terminate its intervention in FERC proceedings.
