Congressional Review Act (CRA): Frequently Asked Questions [Updated January 14, 2020] [open pdf - 1MB]
From the Summary: "The Congressional Review Act (CRA) is an oversight tool that Congress may use to overturn rules issued by federal agencies. 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. Under the CRA, before a rule can take effect, an agency must submit a report to each house of Congress and the comptroller general containing a copy of the rule; a concise general statement describing the rule, including whether it is a major rule; and the proposed effective date of the rule. After receiving the report, Members of Congress have specified time periods during which they must submit and act on a joint resolution of disapproval to take advantage of the CRA's special 'fast track' procedures. If both houses pass the resolution, it is sent to the President for signature or veto. If the President were to veto the resolution, Congress could vote to override the veto."
