Criminal Defense in Pennsylvania: What Defendants Need to Know

Pennsylvania’s criminal justice system is shaped by county-based prosecution, a partially dismantled mandatory minimum structure, progressive reform in Philadelphia, and three active federal judicial districts. Understanding how these elements interact in the specific county or federal court where your case is pending is the foundation of effective defense.

Common Criminal Charges in Pennsylvania

Drug offenses under 35 Pa.C.S. § 780-113 are the most commonly prosecuted felonies in Pennsylvania. Manufacturing, delivery, or possession with intent to deliver carries sentences based on the drug type and quantity, with mandatory minimums for specified amounts of cocaine, heroin, fentanyl, and methamphetamine. DUI under 75 Pa.C.S. § 3802 is classified in tiers based on BAC level: general impairment (.08–.099), high rate (.10–.159), and highest rate (.16+). Second and subsequent DUI offenses carry mandatory minimum jail terms. Firearms offenses under 18 Pa.C.S. § 6105 (persons not to possess firearms) carry up to 10 years. Aggravated assault (18 Pa.C.S. § 2702) is a first-degree felony carrying up to 20 years. Robbery (18 Pa.C.S. § 3701) ranges from third-degree felony to first-degree felony depending on circumstances. Philadelphia processes the highest volume of gun cases in the state.

Alternatives to Traditional Criminal Defense in Pennsylvania

• Accelerated Rehabilitative Disposition (ARD): ARD under Pa.R.Crim.P. 300–320 is Pennsylvania’s primary diversion program for first-time offenders, particularly for DUI and non-violent offenses. Upon successful completion of the program (typically 6–12 months), charges are dismissed and the defendant can petition for expungement. ARD is widely used and highly effective.
• Drug Treatment Courts: Pennsylvania operates drug treatment courts in Philadelphia, Allegheny, and many other counties. Participants receive structured treatment, regular testing, and judicial supervision. Successful completion results in dismissed or reduced charges and provides an alternative to incarceration for defendants with substance use disorders.
• Philadelphia Diversion Programs: The Philadelphia DA’s office offers multiple diversion programs including the Police-Assisted Diversion (PAD) program for low-level drug and prostitution offenses, and expanded pretrial diversion for nonviolent felonies. These programs reflect the DA’s reform-oriented approach and create opportunities that are not available in other Pennsylvania counties.
• Section 17 Probation Without Verdict: Under 35 Pa.C.S. § 780-117, first-time drug offenders can receive probation without verdict. Upon successful completion, the charges are dismissed and the record can be expunged. This is one of the most valuable tools for Pennsylvania drug defendants and should be evaluated in every eligible case.

Pennsylvania’s County-Based Prosecution System and Why It Matters

Pennsylvania’s 67 counties each elect their own district attorney, creating a patchwork of prosecution philosophies that significantly affects outcomes. Philadelphia DA Larry Krasner’s office has declined to prosecute certain marijuana possession cases, expanded diversion programs, reduced reliance on cash bail, and adopted policies that limit use of mandatory minimums. Montgomery County, directly adjacent, takes a more traditional approach. Allegheny County (Pittsburgh) falls somewhere in between. Rural counties in central and northern Pennsylvania often prosecute aggressively with limited diversion options.

For defendants, this means that the same conduct can produce dramatically different outcomes depending on where the offense occurred. A first-time drug possession charge in Philadelphia may be diverted through a diversion program and result in no conviction, while the same charge in a rural county may be prosecuted to the fullest extent. Defense attorneys who understand these county-level differences can advise clients on realistic expectations and develop strategies tailored to the specific prosecution office handling the case.

Mandatory Minimums in Pennsylvania After Hopkins and Alleyne

Pennsylvania’s mandatory minimum sentencing structure has been in flux since the U.S. Supreme Court’s decision in Alleyne v. United States (2013), which held that any fact that increases the mandatory minimum sentence must be found by a jury beyond a reasonable doubt. The Pennsylvania Supreme Court applied this holding in Commonwealth v. Hopkins (2017), striking down several mandatory minimum statutes that relied on judge-found facts.

The practical impact is that some mandatory minimums are no longer enforceable (those that required judge-found facts), while others remain in effect (those based on facts necessarily proven at trial, such as drug weight). Drug trafficking mandatory minimums under 18 Pa.C.S. § 7508 generally survive because drug type and weight are elements of the trafficking charge itself. Firearms mandatory minimums have been more heavily affected. Defense attorneys must track which mandatory minimums are currently enforceable — a task that requires close attention to evolving case law from the Pennsylvania Supreme and Superior Courts. The firms ranked above maintain this knowledge as part of their ongoing practice.
