Alfonso Lopez Jr. is best known for being the petitioner in the landmark Supreme Court case 'United States v. Lopez' (1995), which challenged the constitutionality of the Gun-Free School Zones Act of 1990. The case is significant as it marked a critical moment in the interpretation of federalism, particularly in regards to the limits of Congress's commerce power under the Constitution. This ruling emphasized the importance of state sovereignty and the boundaries of federal authority.
