Health Reform Litigation
Affordable Care Act

Notable Precedents

The decisions in these cases will likely turn on courts’ interpretations of the Commerce Clause, the Necessary and Proper Clause, and the taxing power.

Notable precedential cases involving the Commerce Clause and the taxing power are listed below.
