Individual Mandate, Purely Constitutional
The regulation of an intrastate activity may be essential to a comprehensive regulation of interstate commerce even though the intrastate activity does not itself “substantially affect” interstate commerce. Moreover, as the passage from Lopez quoted above suggests, Congress may regulate even noneconomic local activity if that regulation is a necessary part of a more general regulation of interstate commerce. See Lopez, supra, at 561. The relevant question is simply whether the means chosen are “reasonably adapted” to the attainment of a legitimate end under the commerce power.
The conservative justice of the Supreme Court rests his case.
