A few weeks ago, a federal judge invalidated a crucial provision of the new health care law — a law so complex that few, if any, congressmen read it before voting. In contrast, Judge Henry Hudson’s 42-page opinion is downright pithy. That is because the basic principle is not difficult to understand, and the U.S. Supreme Court — if it follows its own recent precedent — will affirm.

A crucial section of the law is the “individual mandate,” which requires people to buy insurance. The court invalided the mandate. When we remove this cornerstone, the rest of the edifice will fall.
