Analysis of Commonwealth v. Whitcomb: Non-Precedential Decision on Involuntary Intoxication as a DUI Defense

COMMONWEALTH v. WHITCOMB, No. 1502 WDA 2024 (Pa. Super. 08/20/2025)

On August 20, 2025, the Pennsylvania Superior Court issued a non-precedential opinion in Commonwealth v. Whitcomb, 2025 PA Super 180 (J-S18022-25), affirming a judgment of sentence imposed following a DUI conviction under 75 Pa.C.S. § 3802(d)(2). The appellant, Heather Lynn Whitcomb, challenged the trial court’s failure to recognize involuntary intoxication as a cognizable affirmative defense. This decision, while not binding precedent, provides significant insight into the court’s interpretation of statutory and common law defenses in the context of Pennsylvania’s strict liability DUI statute. This article conducts a detailed legal analysis of the opinion, its procedural history, substantive holdings, and practical implications for practitioners.

Factual and Procedural Background

The case originated from an incident on August 11, 2023, in Armstrong County, where Whitcomb exhibited unusual behavior at a gas station on U.S. Route 422. Witnesses observed her standing at the pumps for approximately 20 minutes, swaying, and failing to attend to her child in the vehicle’s back seat. Concerned employees contacted emergency services, prompting a response from Pennsylvania State Police Trooper Patrick Carlson. Field sobriety tests indicated impairment, leading to a Drug Recognition Expert (DRE) evaluation and a subsequent blood draw, which revealed the presence of one controlled substance and several prescribed medications. Whitcomb was charged with DUI under 75 Pa.C.S. §§ 3802(d)(1)(ii), (d)(1)(iii), and (d)(2), as well as careless driving under § 3714(a).

At a bench trial on August 29, 2024, the Court of Common Pleas acquitted Whitcomb of careless driving and the specific-substance DUI charges under §§ 3802(d)(1)(ii) and (d)(1)(iii), but convicted her under § 3802(d)(2), which prohibits driving under the influence of a drug or combination of drugs to a degree impairing safe operation. On November 21, 2024, she received a sentence of 72 hours to six months’ incarceration. Whitcomb filed a timely notice of appeal on December 2, 2024, followed by a court-ordered Pa.R.A.P. 1925(b) statement on January 8, 2025, 15 days late. Despite the delay, the trial court addressed the merits, enabling appellate review.

Legal Issue and Standard of Review

The sole issue on appeal was whether the trial court erred in failing to recognize involuntary intoxication as a cognizable affirmative defense to DUI under 75 Pa.C.S. § 3802(d)(2). This presented a question of law, subject to de novo review with a plenary scope. The court relied on the Statutory Construction Act, 1 Pa.C.S. §§ 1501-1991, to interpret 18 Pa.C.S. § 308, which governs intoxication defenses, emphasizing the ascertainment of legislative intent through plain language unless ambiguous.

Statutory Analysis: 18 Pa.C.S. § 308

Section 308 provides that neither voluntary intoxication nor a voluntary drugged condition constitutes a defense to a criminal charge, nor may such evidence negate intent, except to reduce murder from a higher to a lower degree. Whitcomb argued that the statute’s explicit exclusion of voluntary intoxication implies the availability of an involuntary intoxication defense. However, the Superior Court rejected this inference, noting that § 308 is silent on involuntary intoxication. Citing Commonwealth v. Rivera, 312 A.3d 366, 373 (Pa. Super. 2024), the court held that inserting words into a statute not plainly present is impermissible. Thus, § 308’s silence does not inferentially create the defense, and no other statutory authority supports it in Pennsylvania.

Common Law Analysis and Applicability to Strict Liability DUI

Having found no statutory basis, the court examined whether a common law involuntary intoxication defense, if recognized, would apply to § 3802(d)(2). The appellant relied on Commonwealth v. Smith, 831 A.2d 636 (Pa. Super. 2003), where the court left the defense’s availability to DUI unclear, suggesting it would require the defendant to prove temporary insanity. In Smith, the defendant’s claim of unawareness of a prescription medication’s increased strength enhancing alcohol effects was deemed insufficient without expert testimony.

The court acknowledged that jurisdictions recognizing involuntary intoxication—such as Alaska (Dorsey v. State, 480 P.3d 1211 (Alaska Ct. App. 2021)), New Mexico (State v. Gurule, 252 P.3d 823 (N.M. Ct. App. 2011)), New Jersey (State v. Hammond, 571 A.2d 942 (N.J. 1990)), and Minnesota (City of Minneapolis v. Altimus, 238 N.W.2d 851 (Minn. 1976))—do so when it negates mens rea, actus reus, or induces legal insanity. The Pennsylvania Bar Institute’s suggested jury instruction (Pa. SSJI (Crim) § 8.308C(2)) aligns this defense with the insanity test under 18 Pa.C.S. § 315(b), requiring impairment preventing understanding of the act’s nature or wrongfulness.

Under Commonwealth v. Andre, 17 A.3d 951, 959 (Pa. Super. 2011), Pennsylvania’s insanity defense includes cognitive and moral incapacity prongs, both implicating mens rea. However, § 3802(d)(2) is a strict liability offense, lacking a mens rea element, as affirmed in Commonwealth v. Macik, 319 A.3d 529, 535-36 (Pa. Super. 2024). Other jurisdictions, including Texas (Brown v. State, 290 S.W.3d 247 (Tex. App. 2009)) and Montana (State v. Weller, 208 P.3d 834 (Mont. 2009)), have held involuntary intoxication inapplicable to strict liability DUIs. Consequently, the court concluded that even if the defense exists, it is inapplicable to § 3802(d)(2) due to the absence of a culpable mental state requirement.

Conclusion and Non-Precedential Status

The court held that neither statutory nor common law supports involuntary intoxication as a defense to § 3802(d)(2) DUI. As a non-precedential decision, Whitcomb does not bind future panels but offers persuasive guidance. The trial court’s refusal to recognize the defense was not erroneous, and no relief was warranted. The judgment of sentence was affirmed, with jurisdiction relinquished on August 20, 2025.

Implications for Practice

This non-precedential ruling reinforces Pennsylvania’s strict liability approach to DUI under § 3802(d)(2), limiting defenses tied to mental state. Practitioners should focus on suppression motions (e.g., challenging blood draw procedures), ARD eligibility, or mitigation emphasizing prescribed medications’ non-criminal context. While not controlling, the decision aligns with Macik and signals judicial reluctance to expand defenses in this area. Counsel must adapt strategies accordingly, particularly for clients on legitimate prescriptions, ensuring robust evidentiary challenges or alternative resolutions.
