When will my prior DUI count for my sentence in my new case?

The Pennsylvania Supreme Court has decided the case of Commonwealth v. Mock, holding that the ten-year look back period for DUI offenses begins at the time of the conviction for the previous DUI, not when the defendant committed the prior DUI. This case is significant because in Pennsylvania, if you are convicted of a driving under the influence you could be subject to a mandatory minimum sentence. The mandatory minimum depends on whether you have any prior convictions for DWI, and a prior conviction can make the potential mandatory minimum significantly worse. Therefore, this case can make the potential exposure for a DUI worse for some defendants.

Commonwealth v. Mock

On June 3, 2006, the defendant was arrested for DUI. He was subsequently convicted of that DUI on March 27, 2007. Approximately ten years after he was arrested for his prior DUI, the defendant was arrested again for another DUI. Specifically, on July 10, 2016, at approximately 1:00 A.M., an officer with the Mifflin County Police Department stopped the defendant after observing him cross the fog and center lines several times while driving on the highway. The officer then arrested him and the defendant subsequently consented to a blood test which revealed a blood alcohol content of .21%. He was then charged with DUI-highest rate of alcohol.

Because of his prior conviction, the Commonwealth deemed the instant offense a second offense and graded it as a misdemeanor of the first degree. This is significant because it subjected the defendant to increased penalties. Before proceeding to trial, the defendant filed a motion to quash the information, arguing that the Commonwealth improperly characterized the new charge as a second offense. The defendant argued that § 3806(b) negates his 2006 conviction’s applicability because that DUI occurred in in June 2006, which was more than ten years from the date of his current offense.

The trial court rejected the defendant’s argument. The court’s logic was that because the defendant was not convicted of his prior offense until March 2007, his current DUI fell within the 10-year look back period of § 3806. In other words, it did not matter that he was arrested for his DUI in June of 2016; all that mattered was that he was convicted of the new offense in 2017. The defendant then proceeded to a stipulated bench trial and was convicted of DUI-highest rate of alcohol, as a second offense. The trial court sentenced the defendant to the mandatory minimum sentence of 90 days to five years imprisonment, as well as fines, costs, and related penalties. The defendant then filed a timely appeal to the Pennsylvania Superior Court.

The Defendant’s Appeal to the Superior Court

On appeal, the defendant argued that the Commonwealth improperly characterized the new offense as a second offense which subjected the defendant to enhanced grading and sentencing penalties. The Superior Court, in a divided opinion, denied the defendant’s appeal. The majority stated that it had analyzed the plain language of the statute and determined that “any conviction, regardless of timing, counts as a ‘prior offense.’” The majority therefore agreed with the trial court’s conclusion that the defendant’s DUI was properly graded as a second offense because his earlier conviction took place within ten years of his commission of the present offense. The defendant then filed a petition for allowance of appeal with the Pennsylvania Supreme Court. The Pennsylvania Supreme Court agreed to hear his case to resolve the question of, for purposes of § 3806, whether the court should use the date of the defendant’s conviction or the date of when the DUI occurred.

Why Does It Matter When I Was Convicted of My Previous DUI or When I Committed It?

The reason it matters is because of § 3806. § 3806 holds that if someone has a prior DUI conviction within ten years of their current DUI, then they are subjected to increased penalties. This is significant because in Pennsylvania, if you are convicted of a DUI you will be subjected to a mandatory minimum. The mandatory minimums differ depending on the particular DUI that you were convicted of. For example, let’s assume you are found guilty of § 3802 (D)(2) (driving while under the influence of a controlled substance. This is your first DWI so you will be subjected to the mandatory minimum of three days incarceration. However, if this was your second DWI, then you will be forced to serve 90 days incarceration. This is also a mandatory minimum sentence, and therefore the judge does not have discretion to lower the sentence. As one can see, the timing of one’s prior DUI can have profound consequences for an individual.

The Pennsylvania Supreme Court’s Decision

The Pennsylvania Supreme Court denied the defendant’s appeal. In making its decision, the Pennsylvania Supreme Court was generally dismissive of the defendant’s argument. The Court analyzed the language of the § 3806 and found that it was clear that the ten-year look back period runs from the occurrence date of the present offense to the conviction date of the earlier offense. The Court concluded that this language is “unambiguous.” Further, the Court stated that if the Court were to adopt his interpretation of the statute it would produce “an absurd result” and that his reading of the statute was “merely a means to a preferred end.” As such, the Court found that the defendant was properly sentenced as a second-time offender. Consequently, the defendant will not get any relief and he will be forced to serve his sentence.
