Alexander v. Commomwealth

This appeal raises questions regarding the application of the Ignition Interlock Devices Law (hereinafter, "Interlock Law"), 42 Pa.C.S. § 7001 et seq. (repealed), to a recidivist driving under the influence ("DUI") offender, where one or more of the offenders earlier convictions occurred before the enactment of the Interlock Law. The Commonwealth Court panel below held that it is an unlawfully retroactive application of the Interlock Law to enforce the interlock requirement on the basis of convictions which occurred before the statute was enacted. We disagree, and accordingly, we reverse.
