[1947] 92-706.1, RCM Dean v. Montana Power Company [4/11/00] 2000 MTWCC 21 Where statute in effect at time of work injury has been repealed or amended, the statute still applies to substantive rights (here, the right to medical benefits for 36 months and to extended benefits for good cause), but current procedures for dispute resolution apply. Thus, WCC had jurisdiction to resolve dispute over extension of medical benefits where no current statute continues said jurisdiction in Division, which no longer exists, or places such jurisdiction in Department of Labor.
