Federal Power Commission v. Mobile Gas Service Corp.

Opinion summary

Etalia.ai summary of the majority opinion

The case addressed whether a natural gas company could unilaterally change the rates specified in its contract with a customer by filing new rates with the Federal Power Commission (FPC). The Supreme Court held that under the Natural Gas Act, such contracts are binding and cannot be altered without mutual agreement. The ruling emphasized that rate changes must adhere to contractual terms unless both parties consent or specific statutory procedures for modification are followed. This decision reinforced the stability of long-term contracts within regulated industries, ensuring that companies cannot bypass agreed-upon terms simply through regulatory filings.
