In the case Federal Power Commission v. Colorado Interstate Gas Co., the U.S Supreme Court ruled in favor of the Federal Power Commission (FPC). The issue at hand was whether or not FPC had jurisdiction over sales for resale of natural gas produced and sold by an independent producer, who also owned a pipeline system that transported gas from its source to points within a single state. The court held that such sales were subject to federal regulation under the Natural Gas Act because they involved interstate commerce. This decision expanded FPC's regulatory authority, emphasizing that Congress intended for it to regulate all aspects of natural gas affecting interstate commerce directly or indirectly.

In the dissenting opinion for Federal Power Commission v. Colorado Interstate Gas Co., Justice Robert H. Jackson disagreed with the majority's interpretation of the Natural Gas Act, arguing that it was not intended to give such broad regulatory power to the Federal Power Commission (FPC). He contended that Congress did not intend for FPC jurisdiction over sales of natural gas solely because they were made in interstate commerce; rather, he believed this authority should only extend to situations where state regulation would be inadequate or ineffective. Furthermore, he argued that there is a distinction between production and sale activities which must be recognized by law - while states have traditionally regulated production aspects like drilling and extraction operations, federal control has been limited mainly towards transportation and sale across state lines. Thus, according to him, extending FPC’s reach into direct sales from producers could potentially disrupt this balance of powers.
