There is no doubt that a state can constitutionally require citizens to have health insurance. Why, then, is the Supreme Court fussing over the constitutionality of the individual mandate provision of the Affordable Care Act?
The answer is simple. States have plenary authority to legislate on matters of public policy. The national government, however, is a government of limited powers. It cannot constitutionally act unless the Constitution authorizes it to do so. The central question in the case now pending before the Supreme Court is whether the Constitution grants Congress the authority to require individuals to have health insurance. Opponents of the law argue that it exceeds the legitimate authority of the national government.
The government defends the constitutionality of the individual mandate on the basis of the Commerce Clause of the Constitution, which provides in Article I, Section 8, that Congress shall have the power “to regulate Commerce … among the several States.”
Over time, the Supreme Court has held that under this provision Congress can constitutionally regulate activity if, in the aggregate, it has “a substantial economic effect on interstate commerce.” Moreover, as Justice Rehnquist explained in 1995, the Court’s role in determining the constitutionality of federal legislation under the Commerce Clause is limited to deciding whether Congress “had a rational basis … for concluding that a regulated activity sufficiently affected interstate commerce” to merit federal action.
