Nipsco Industrial Group, Appellant (intervenor Below) v. Northern Indiana Public Service Company, Appellee…

Summary

The Indiana Supreme Court affirmed the Commission's approval of NIPSCO's second periodic rate-adjustment petition. It held that the Industrial Group was estopped from challenging allocation factors it had supported in earlier settlements and proceedings, and that the Commission's order contained sufficient findings. Justice Slaughter, dissenting and joined by Justice David, would have treated the issue as a legal question and affirmed the Court of Appeals' contrary decision.
