The Supreme Court has expressed an interest "that Congress be able to legislate against a background of clear interpretive rules, so that it may know the effect of the language it adopts." This report identifies and describes some of the more important rules and conventions of interpretation that the Court applies. Because the Court has recently placed renewed emphasis on statutory text and somewhat reduced emphasis on legislative history and other interpretive sources "extrinsic" to the text, this report focuses primarily on the Court's methodology in construing statutory text. The Court's recent approaches to reliance on legislative history are also briefly described.
