That’s how I describe the individual mandate in my contribution to SCOTUSblog’s online symposium on Obamacare, which Trevor Burrus has already highlighted.  Here’s an excerpt:

All the Obamacare legal challenges boil down to Congress’s authority – or lack thereof – to require people to buy private insurance.  Although unfortunately not dispositive of modern judicial decisions, the text of the Constitution demands that the Supreme Court strike down the individual mandate as an unconstitutional exercise of Congress’s power to regulate interstate commerce.  Finding the mandate constitutional would be the first interpretation of the Commerce Clause to permit the regulation of inactivity – in effect requiring an individual to engage in an economic transaction.

Moreover, upholding Obamacare would grant the federal government wide latitude to mandate that Americans engage in activities of its choosing.  An expansive holding here would fundamentally alter the relationship between the government and the people.  If the challenges fail, there will be no principled limits on federal power.

I go on to describe the current state of play at the appellate and outline what we can expect going forward, as well as providing links to useful resources on this issue.  Read the whole thing.
