Editing Sherman Antitrust Act (section)

===Constitutional basis for legislation===
Congress claimed power to pass the Sherman Act through its [[Commerce Clause|constitutional authority to regulate interstate commerce]]. Therefore, federal courts only have jurisdiction to apply the Act to conduct that restrains or substantially affects either interstate commerce. (Congress also has ultimate authority over economic rules within the District of Columbia and US territories under the 17th [[Enumerated powers (United States)|enumerated power]] and the [[Article Four of the United States Constitution#Clause 2: Property Clause|Territorial Clause]], respectively.) This requires that the plaintiff must show that the conduct occurred during the flow of interstate commerce or had an appreciable effect on some activity that occurs during interstate commerce.{{facts|date=September 2024}}
