The U.S. Supreme Court case Colorado-Wyoming Gas Co. v. Federal Power Commission et al., 1944, centered around the jurisdiction of the Federal Power Commission (FPC) over natural gas companies operating within a single state but selling to interstate pipelines. The Colorado-Wyoming Gas Company argued that because it only operated in one state, its rates should not be regulated by the FPC under the Natural Gas Act of 1938 which was designed for interstate commerce regulation. However, since their product eventually reached other states through sales to an interstate pipeline company, they were deemed subject to federal regulation by lower courts and this decision was upheld by the Supreme Court on appeal. The court ruled that even though Colorado-Wyoming's operations were intrastate in nature, their sale of gas destined for out-of-state consumers made them part of an overall scheme of interstate commerce and thus fell under federal jurisdiction as per Congress' intent when passing the Natural Gas Act.

The dissenting opinion in the case of Colorado-Wyoming Gas Co. v. Federal Power Commission et al., 1944, argued that the Federal Power Commission (FPC) did not have jurisdiction over sales of natural gas by producers to pipelines for resale because such transactions were part of interstate commerce and thus outside FPC's regulatory authority under the Natural Gas Act. The dissenters contended that Congress had intended to exclude production and gathering from regulation when it passed this act, as these activities are inherently local in nature. They also pointed out that allowing FPC to regulate these aspects would lead to a significant expansion of federal power into areas traditionally controlled by states, potentially undermining state sovereignty and disrupting established industry practices.
