The United States Supreme Court case, United States v. Georgia Public Service Commission in 1962 involved a dispute over the rates charged by Southern Bell Telephone and Telegraph Company for interstate services. The Federal Communications Commission (FCC) had approved these rates but the Georgia Public Service Commission insisted on lower charges within its jurisdiction. The U.S. government sued on behalf of the FCC, arguing that federal law preempted state regulation in this area due to its interstate nature. The Supreme Court ruled unanimously in favor of the U.S., stating that when there is a conflict between state and federal regulations concerning interstate commerce, federal law prevails as per Supremacy Clause of Constitution Article VI clause 2 . Therefore, states cannot interfere with or regulate areas reserved exclusively for federal control such as interstate communication service rates.

The dissenting opinion in the case of United States v. Georgia Public Service Commission argued that the Supreme Court should not have jurisdiction over state regulatory bodies like the Georgia Public Service Commission. The justices who dissented believed that this was a matter for state courts, not federal ones, and they were concerned about setting a precedent where federal courts could intervene in matters traditionally handled by states. They also felt that there wasn't sufficient evidence to prove discrimination against out-of-state businesses as claimed by the U.S government. Furthermore, they disagreed with majority's interpretation of Commerce Clause which allowed Congress to regulate interstate commerce extensively including intrastate activities affecting it; instead arguing for more limited understanding of clause focusing on preventing trade barriers between states rather than extensive regulation within them.
