Narrative Opinion Summary
This case involves a dispute between Indiana Gas Company, Inc. (Appellant) and the Office of the Utility Consumer Counselor and the Indiana Utility Regulatory Commission (Appellees) concerning the application of an 'earnings test' in gas cost adjustment (GCA) applications. Under Indiana Code 8-1-2-42(g), GCAs permit utilities to adjust customer charges in response to gas cost fluctuations. The core legal issue is whether the earnings test, which limits adjustments to prevent excess earnings, applies to GCAs reflecting reduced costs. Indiana Gas contends that such adjustments should not trigger the earnings test, whereas the Commission asserts comprehensive application to prevent earnings beyond authorized returns. The court examined the applicability of res judicata, concluding that it does not apply to legislative actions like rate-making, enabling Indiana Gas to challenge the earnings test's application. The court also affirmed that retroactive rate-making rules are inapplicable to GCAs. The Commission ordered refunds for excess earnings in GCA26 and GCA27, which were upheld despite not explicitly stating they were 'subject to refund.' The case is remanded for further proceedings by the Commission to re-evaluate these issues, emphasizing the prospective nature of GCAs and the Commission's authority to mandate refunds. Judges Barteau and Rucker concurred with the decision.
