219 A.3d 1155
Pa.2019Background
- Michael Mock committed a DUI on June 3, 2006 (convicted March 27, 2007) and later committed a second DUI on July 10, 2016 (BAC 0.21%).
- Commonwealth charged the 2016 offense as a second DUI under 75 Pa.C.S. §§ 3802(c), 3803(b)(4), 3804(c)(2), invoking § 3806’s ten-year lookback for prior offenses.
- Mock moved to quash, arguing § 3806’s ten-year period runs from the present offense date to the earlier offense’s occurrence date (not its conviction date), relying on Commonwealth v. Haag.
- Trial court denied the motion; Mock was convicted in a stipulated bench trial and sentenced under the mandatory second-offense range (90 days minimum).
- Superior Court (published, divided) affirmed, holding § 3806’s subsection (a) definition of “prior offense” (a conviction) applies and subsection (b) imposes timing limits measured to the prior conviction date.
- Supreme Court of Pennsylvania affirmed: the plain statutory text requires measuring the ten-year lookback from the current offense date to the conviction date of the earlier offense.
Issues
| Issue | Plaintiff's Argument (Mock) | Defendant's Argument (Commonwealth) | Held |
|---|---|---|---|
| Whether § 3806’s ten-year lookback runs to the earlier offense’s occurrence date or to its conviction date | Lookback runs from present offense to occurrence date of prior offense; Haag supports that subsection (b) overrides (a) and focuses on occurrence | Lookback runs from present offense to prior conviction date; subsection (a)’s definition of “prior offense” (a conviction) governs and subsection (b) only limits timing | Ten-year lookback runs from the present offense date to the conviction date of the earlier offense; prior conviction within ten years = second offense |
| Whether Commonwealth v. Haag controls interpretation of current § 3806 | Haag requires treating subsection (b) as redefining "prior offense" to reference occurrence date | Statute was amended after Haag; current text removed the redefining language so Haag is not controlling | Haag is not dispositive here because legislature revised § 3806; current text unambiguously incorporates subsection (a)’s conviction-based definition into subsection (b)’s timing limits |
| Whether the Court should adopt Mock’s reading to avoid prosecutorial manipulation by delaying conviction | Mock: measuring to occurrence date prevents Commonwealth from extending lookback by delaying convictions | Commonwealth/PDAA: recidivist statute requires convictions; measuring to conviction date avoids rewarding defendants who delay sentencing | Court applies plain text over policy concerns and rejects the manipulation argument; conviction-date measurement stands |
