Although the Constitution serves as the Supreme Law of the Land, how should its provisions be interpreted over two hundred years after it was drafted? The Supreme Court of the United States sometimes relies on certain methods of interpretation—that is, ways of interpreting a particular constitutional provision. This two-part podcast describes the most common methods of constitutional interpretation; discusses examples of Supreme Court decisions that demonstrate the application of these methods; and provides a general overview of the various arguments in support of, and in opposition to, the use of such methods of constitutional interpretation. Part I discusses two of the most commonly used methods of constitutional analysis: textualism and originalism.
