Final answer:
Yes, it is true that the Supreme Court ruled Congress exceeded its commerce clause powers by creating gun-free zones around schools in the case of United States v. Lopez.
Step-by-step explanation:
It is true that in the United States, the Supreme Court stated that Congress had exceeded its commerce clause power by creating gun-free zones around schools. This decision occurred in the case of United States v. Lopez in 1995, where the Supreme Court ruled that the Gun-Free School Zones Act of 1990 was an unconstitutional overreach of Congress's powers regarding the commerce clause. The case marked a shift in the Court's approach to the commerce clause, narrowing its interpretation and reaffirming the authority of states over certain issues.
