29 C.F.R. § 2570.150
The rules of practice set forth in this subpart H apply to "section 3(40) Finding Proceedings" (as defined in § 2570.152(g) ), under section 3(40) of the Employee Retirement Income Security Act of 1974 (ERISA or the Act). Refer to 29 CFR 2510.3-40 for the definition of relevant terms of section 3(40) of ERISA, 29 U.S.C. 1002(40) . To the extent that the regulations in this subpart differ from the regulations in subpart A of 29 CFR part 18, the regulations in this subpart apply to matters arising under section 3(40) of ERISA rather than the rules of procedure for administrative hearings published by the Department's Office of Administrative Law Judges in subpart A of 29 CFR part 18. These proceedings shall be conducted as expeditiously as possible, and the parties shall make every effort to avoid delay at each stage of the proceedings.
