Congressional Review Act: Determining Which 'Rules' Must Be Submitted to Congress [September 24, 2018] [open pdf - 2MB]
"The Congressional Review Act (CRA) allows Congress to review certain types of federal agency actions that fall under the statutory category of'rules.' The CRA requires that agencies report their rules to Congress and provides special procedures under which Congress can consider legislation to overturn those rules. A joint resolution of disapproval will become effective once both houses of Congress pass a joint resolution and it is signed by the President, or if Congress overrides the President's veto. The CRA generally adopts a broad definition of the word 'rule' from the Administrative Procedure Act (APA), defining a rule as' the whole or a part of an agency statement of general or particular applicability and future effect designed to implement, interpret, or prescribe law or policy or describing the organization, procedure, or practice requirements of an agency.'"
