“The power to regulate commerce presupposes the existence of commercial activity to be regulated. . . . The individual mandate, however, does not regulate existing commercial activity. It instead compels individuals to become active in commerce by purchasing a product, on the ground that their failure to do so affects interstate commerce. Construing the Commerce Clause to permit Congress to regulate individuals precisely because they are doing nothing would open a new and potentially vast domain to congressional authority. . . . Allowing Congress to justify federal regulation by pointing to the effect of inaction on commerce would bring countless decisions an individual could potentially make within the scope of federal regulation, and — under the government’s theory — empower Congress to make those decisions for him.”
If the mandate had been upheld under the Commerce Clause, the Supreme Court would have decisively construed this clause so permissively as to give Congress an essentially unlimited police power — the power to mandate, proscribe and regulate behavior for whatever Congress deems a public benefit. Instead, the court rejected the Obama administration’s Commerce Clause doctrine. The court remains clearly committed to this previous holding: “Under our written Constitution . . . the limitation of congressional authority is not solely a matter of legislative grace.”
The court held that the mandate is constitutional only because Congress could have identified its enforcement penalty as a tax. The court thereby guaranteed that the argument ignited by the mandate will continue as the principal fault line in our polity.
The mandate’s opponents favor a federal government as James Madison fashioned it, one limited by the constitutional enumeration of its powers. The mandate’s supporters favor government as Woodrow Wilson construed it, with limits as elastic as liberalism’s agenda, and powers acquiring derivative constitutionality by being necessary to, or efficient for, implementing government’s ambitions.
By persuading the court to reject a Commerce Clause rationale for a president’s signature act, the conservative legal insurgency against Obamacare has won a huge victory for the long haul. This victory will help revive a venerable tradition of America’s political culture, that of viewing congressional actions with a skeptical constitutional squint, searching for congruence with the Constitution’s architecture of enumerated powers. By rejecting the Commerce Clause rationale, Thursday’s decision reaffirmed the Constitution’s foundational premise: Enumerated powers are necessarily limited because, as Chief Justice John Marshall said, “the enumeration presupposes something not enumerated.”
