Charles Krauthammer‘s latest column previews the upcoming U.S. Supreme Court review of the federal health care reform law.

Beginning March 26, the Supreme Court will hear challenges to the law. The American people, by an astonishing two-thirds majority, want the law and/or the individual mandate tossed out by the Court. In practice, however, questions this momentous are generally decided 5 to 4, i.e., they depend on whatever side of the bed Justice Anthony Kennedy gets out of that morning.

Ultimately, the question will hinge on whether the Commerce Clause has any limits. If the federal government can compel a private citizen, under threat of a federally imposed penalty, to engage in a private contract with a private entity (to buy health insurance), is there anything the federal government cannot compel the citizen to do?

If Obamacare is upheld, it fundamentally changes the nature of the American social contract. It means the effective end of a government of enumerated powers — i.e., finite, delineated powers beyond which the government may not go, beyond which lies the free realm of the people and their voluntary institutions. The new post-Obamacare dispensation is a central government of unlimited power from which citizen and civil society struggle to carve out and maintain spheres of autonomy.
