Under the Congressional Review Act, a covered agency regulation takes effect as provided by law unless Congress disapproves the rule with a joint resolution of disapproval. In contrast, the Regulations from the Executive In Need of Security (REINS) Act would generally require the enactment of a joint resolution of approval before any "major rule" could take effect. This book provides information on the types of "major rules" that may be covered by the REINS Act, if enacted. Specifically, it identifies how many major rules have been issued in recent years, and which agencies have issued them along with identifying why certain rules published during calendar year 2010 were considered to be major rules under the CRA.
