Professor Notes

In United States v. Darby Lumber Co., the Supreme Court affirmed the broad scope of Congress's authority under the Commerce Clause. This case illustrates an essential transition in constitutional interpretation regarding federal power over labor conditions tied to interstate commerce. The Court emphasized that even if a company primarily operates intrastate, if its activities affect interstate commerce, federal regulation is justified. Understanding the balance between state rights and federal authority is crucial for students, especially as it pertains to the Tenth Amendment's implications on federal regulation of economic activities.

This is a pivotal case in laying the groundwork for a robust federal regulatory framework in various economic contexts.
