49 CFR 1016.102: When the Act applies.

The Act applies to any adversary adjudication pending before the Board after October 1, 1981. This includes proceedings begun before October 1, 1981, if final Board action has not been taken before that date, regardless of when they were initiated or when final Board action occurs. These rules incorporate the changes made in Pub. L. No. 99-80, 99 Stat. 183, which applies generally to cases instituted after October 1, 1984. If awards are sought for cases pending on October 1, 1981 or filed between that date and September 30, 1984, the prior statutory provisions (to the extent they differ from the existing ones, and our implementing rules) apply.
