The Congressional Research Service (CRS) developed the Congressional Oversight Manual over 30 years ago, following a three-day December 1978 Workshop on Congressional Oversight and Investigations. The workshop was organized by a group of House and Senate committee aides from both parties and CRS at the request of the bipartisan House leadership. The Manual was produced by CRS with the assistance of a number of House committee staffers. In subsequent years, CRS has sponsored and conducted various oversight seminars for House and Senate staff and updated the Manual as circumstances warranted. The Congressional Review Act (CRA) is an oversight tool that Congress may use to overturn a rule issued by a federal agency. The CRA was included as part of the Small Business Regulatory Enforcement Fairness Act (SBREFA), which was signed into law on March 29, 1996. The CRA requires agencies to report on their rulemaking activities to Congress and provides Congress with a special set of procedures under which to consider legislation to overturn those rules. This book discusses both the Congressional Oversight Manual and the Congressional Review Act in detail.
