This rule removes from the Code of Federal Regulations certain interpretive bulletins and regulations (or portions thereof) under the Employee Retirement Income Security Act of 1974 (ERISA), that the Department of Labor (the Department) believes are obsolete (collectively, the obsolete regulations). The obsolete regulations generally provided transitional relief for plan sponsors, plan administrators, and others subject to the requirements of title I of ERISA, in coming into compliance with ERISA's requirements in the first several years following ERISA's enactment in 1974. Because the election periods or dates of applicability under these rules have expired, the Department believes that the regulations are no longer needed. In other instances, the obsolete regulations are unnecessary because they merely provide notice of a rescission or withdrawal of prior guidance or regulations, or were rendered ineffective by a subsequent Supreme Court decision.
