A bill to amend title 1, United States Code, to clarify the effect and application of legislation.

Declares that any Act of Congress enacted after the effective date of this Act shall be prospective in application only, and shall not create a private claim or cause of action, unless a provision of such Act expressly specifies otherwise.

Directs a court, in applying such provision, to determine the relevant retroactivity event in an Act of Congress (if such event is not specified in that Act) for purposes of determining if the Act: (1) is prospective in application only; and (2) affects conduct that occurred before the Act's effective date.
