In Rauch v. Workers' Compensation Appeal Board (Kids Wear Services, Inc.), 808 A.2d 291 (Pa. Cmwlth. 2002), appeal denied, 572 Pa. 751, 816 A.2d 1103 (2003), the Court held that a 1996 amendment to section 314 of the Act, allowing employers to compel a claimant to submit to an expert interview, was a procedural modification that could be applied to proceedings on a claimant's 1994 injury because the provision merely provided a means by which employers may secure pertinent information and had no effect on a claimant's substantive right to receive benefits under a particular set of facts.
