1. A high school student in San Antonio, Texas, who brought an unloaded handgun to
school was charged with violating the Gun-Free School Zones Act of 1990. The
student challenged the charge, claiming that Congress did not have the power to
override state law within public schools. In the 1995 case United States v. Lopez, the
Supreme Court ruled that Congress did not have the power to regulate public
schools. Instead, the Court found that that power belonged to individual states.
Explain which constitutional principle this scenario illustrates. What evidence led you
to that conclusion? (1 point)
