Answer
United States v. Morrison, a landmark case decided in 2000, saw Chief Justice William Rehnquist authoring the majority opinion. The case centered on the Violence Against Women Act of 1994, challenging its constitutionality based on Congress's power under the Commerce Clause. Rehnquist's opinion ultimately struck down a portion of the law, asserting that the federal government overstepped its authority in regulating intrastate violence against women.
