BEFORE: PANELLA, P.J.E., OLSON, J., and KUNSELMAN, J.

OPINION BY KUNSELMAN, J.:                          FILED: SEPTEMBER 10, 2024

       Michael Anthony Cahill appeals from the judgment of sentence entered

after he was convicted of obstructing administration of law, resisting arrest,

driving under the influence (DUI), possession of a small amount of marijuana,

possession of drug paraphernalia, and driving with an obscured registration

plate.1 Police stopped him for driving with a license plate cover, after this

Court’s decision in Commonwealth v. Ruffin, 
282 A.3d 796
 (Pa. Super.

2022) (holding any partial license plate cover violates Section 1332 of the

Vehicle Code), and before the enactment of Act 112 of 2022 (amending

Section 1332 to permit some license plate frames). We hold the trial court

properly denied suppression because the police had probable cause to suspect

that Cahill violated the law as it existed at the time of the stop. Further, we

1 18 Pa.C.S. §§ 5101, 5104, 75 Pa.C.S. § 3802(d)(2), 35 P.S. § 780-

J-S26037-24



find the evidence sufficient to sustain Cahill’s convictions for DUI and resisting

arrest. Accordingly, we affirm.

      This case arose from an incident on September 28, 2022, when Trooper

Bradley Fornwalt of the Pennsylvania State Police stopped Cahill in Adams

County, Pennsylvania.      Trooper Fornwalt charged Cahill with the above

offenses and three moving violations. The charges were held for court.

      Cahill moved to suppress evidence from the traffic stop. The trial court

held a hearing and found that Trooper Fornwalt observed Cahill driving with a

license plate cover that prevented him from reading the license plate from

approximately 20 feet away. The court concluded that the ensuing traffic stop

was supported by probable cause that Cahill violated Section 1332(b) of the

Vehicle Code in effect at the time of the stop. The court denied suppression.

      The case proceeded to a non-jury trial. Trooper Fornwalt was the only

witness. The trial court recounted the facts as follows:

      On September 28, 2022, at approximately 10:24 AM, Trooper
      Bradley Fornwalt . . . of the Pennsylvania State Police was in a
      marked patrol vehicle in Straban Township, Adams County,
      Pennsylvania. Trooper Fornwalt has approximately five years of
      law enforcement experience. He has received Standard Field
      Sobriety Test and ARIDE training.           He has conducted
      approximately 350 DUI investigations, of which 250–280 involved
      marijuana.

      Trooper Fornwalt observed a grey Honda Accord driving with tags
      that he could not read because of a covering over the license plate.
      Trooper Fornwalt then effectuated a traffic stop [based on the
      obscured registration plate].

      [Cahill] was driving the Honda Accord and lit a cigarette as
      Trooper Fornwalt approached. Once the cigarette was put out,
      Trooper Fornwalt could smell the odor of burnt marijuana.

                                      -2-
J-S26037-24


     Trooper Fornwalt observed [Cahill] had red, bloodshot, and glassy
     eyes. [Cahill] told Trooper Fornwalt that there was marijuana in
     the car and that he was a medical marijuana user in Maryland, but
     he did not have a Pennsylvania card. There were two containers
     of labeled marijuana in the car, but they were not packaged
     properly based on Pennsylvania regulations . . . . Based on these
     observations, Trooper Fornwalt believed [Cahill] was under the
     influence of a controlled substance and ordered [Cahill] to exit the
     vehicle.

     [Cahill] performed several Standard Field Sobriety Tests and
     ARIDE tests. During the Walk and Turn Test, [Cahill] started the
     test too soon, had an improper turn, and raised his arms on the
     return walk. During the One-Leg Stand Test, [Cahill] was swaying
     and put his foot down after 26 seconds. During the Modified
     Romberg Test, [Cahill] had eyelid tremors and swayed in a circular
     motion. During the Lack of Convergence Test, [Cahill’s] left eye
     did not converge. Trooper Fornwalt testified that these were all
     indicators that [Cahill] was under the influence of a controlled
     substance.    Additionally, [Cahill] gave consent for Trooper
     Fornwalt to search his vehicle, and Trooper Fornwalt found a metal
     grinder and a smoking device. Based on these observations, and
     based on his training and experience, Trooper Fornwalt believed
     [Cahill] was under the influence of a controlled substance to a
     degree rendering him incapable of safe driving. Trooper Fornwalt
     then placed [Cahill] under arrest for driving under the influence.

     [Cahill] refused to consent to a blood draw, and he was taken to
     the Pennsylvania State Police Gettysburg Station.              Trooper
     Fornwalt began the process of obtaining a search warrant, but
     [Cahill] kept asking to see a lawyer or see a judge. Trooper
     Fornwalt explained that he had to finish the search warrant first.
     [Cahill] was seated on a bench, handcuffed. [Cahill] began
     banging his head on the wall. [Cahill] hit his head hard enough
     that the whole wall shook and a Lieutenant a few rooms over could
     hear it. Several officers had to stop [Cahill] and restrain him to
     keep him from injuring himself. After [Cahill] was given a chance
     to calm down, [Cahill] refused, and it required six officers to
     restrain him. The officers then decided to take [Cahill] to a patrol
     vehicle to transport him to the prison. [Cahill] kicked his feet and
     flailed around. Multiple officers had to hold his arms, midsection,
     and feet while he was on the ground. Multiple troopers had to
     assist with taking [Cahill] to the patrol vehicle. One trooper had
     to sit in the back of the patrol vehicle with [Cahill] to hold his head
     still, which Trooper Fornwalt testified was not usually required.

                                      -3-
J-S26037-24


      [Cahill’s] actions prevented Trooper Fornwalt from completing the
      process of obtaining a search warrant for a blood draw, and no
      blood draw was taken.

Trial Court Opinion, 2/13/24, at 1–4 (footnotes omitted).

      The trial court found Cahill guilty of obstructing administration of law,

resisting arrest, DUI, possession of a small amount of marijuana, possession

of drug paraphernalia, and driving with an obscured registration plate and not

guilty of the three moving violations. On January 11, 2024, the trial court

sentenced Cahill to an aggregate term of 3 to 6 months of confinement,

concurrent with 24 months of probation.

      Cahill timely appealed on January 25, 2024. Cahill and the trial court

complied with Pennsylvania Rule of Appellate Procedure 1925. Cahill presents

three issues for review:

      Whether the trial court erred in denying [Cahill’s] Motion for
      Suppression of Evidence, inasmuch as Trooper Fornwalt lacked
      probable cause or reasonable suspicion required to initiate a traffic
      stop?

      Whether the evidence presented at trial was sufficient to prove
      beyond a reasonable doubt that [Cahill] was guilty of driving under
      the influence of a controlled substance to such an extent that he
      was incapable of safe driving?

      Whether the evidence presented at trial was sufficient to prove
      [Cahill’s] guilt of resisting arrest beyond a reasonable doubt?

Cahill’s Brief at 4 (format altered).

      Cahill first challenges the denial of his motion to suppress evidence. He

argues that Trooper Fornwalt used the obstructed license plate as a pretext to




                                        -4-
J-S26037-24



stop him,2 but the stop was based on a mistake of law and thus lacked

probable cause. Specifically, Cahill claims this Court’s opinion in Ruffin “was

in error” based on subsequent legislation, so Trooper Fornwalt could not rely

on our interpretation of Section 1332 to initiate a traffic stop.

       We apply the following standard:

       Our review is limited to determining whether the record supports
       the findings of fact of the suppression court and whether the legal
       conclusions drawn from those findings are correct. We are bound
       by the factual findings of the suppression court, which are
       supported by the record, but we are not bound by the suppression
       court’s legal rulings, which we review de novo.

Commonwealth v. Mendoza, 
287 A.3d 457, 462
 (Pa. Super. 2022) (quoting

Commonwealth v. James, 
69 A.3d 180, 186
 (Pa. 2013)). Where the factual

findings are not in dispute, this Court applies the same legal standard as the

suppression court—here, to determine whether Trooper Fornwalt had a

constitutionally sufficient basis to stop Cahill. See 
id.
 at 463 n.5.

       A traffic stop is a “seizure” for constitutional purposes, entitling the

subject of the stop to protection against unreasonable searches and seizures.

Commonwealth v. Malloy, 
257 A.3d 142
, 147–48 (Pa. Super. 2021). The

quantum of cause needed to stop a vehicle turns on whether the stop can

“serve a stated investigatory purpose.” 
Id.
 at 148 (quoting Commonwealth

v. Feczko, 
10 A.3d 1285, 1290
 (Pa. Super. 2010) (en banc)). Where further

investigation is needed, e.g., a stop for suspected DUI, an officer needs
____________________________________________


2 Cahill’s premise alone affords him no relief.
                                           Pretextual traffic stops, even for
“minor” offenses, are not unlawful. Whren v. United States, 
517 U.S. 806
,
813–14 (1996); Commonwealth v. Chase, 
960 A.2d 108, 113
 (Pa. 2008).

                                           -5-

reasonable suspicion to initiate a traffic stop. Commonwealth v. Walls, 
206 A.3d 537, 541
 (Pa. Super. 2019). Where further investigation would provide

no additional information, e.g., a stop for an obscured license plate, an officer

needs probable cause. Ruffin, 
282 A.3d at 801
.

       Probable cause for a search or seizure is a “practical, non-technical

concept” that depends on the totality of the circumstances. Commonwealth

v. Barr, 
266 A.3d 25
, 40 (Pa. 2021) (citations omitted).

       In order for a traffic stop to be justified, a police officer must have
       probable cause to believe that a violation of the Vehicle Code or
       regulations has taken place. The officer must be able to articulate
       specific facts possessed by him at the time of the questioned stop,
       which would provide probable cause to believe that the vehicle or
       the driver was in some violation of some provision of the Vehicle
       Code. Probable cause does not require certainty, but rather exists
       when criminality is one reasonable inference, not necessarily even
       the most likely inference.

Commonwealth v. Lindblom, 
854 A.2d 604, 607
 (Pa. Super. 2004) (quoting

Commonwealth v. Mickley, 
846 A.2d 686, 689
 (Pa. Super. 2004)).

       Under the United States Constitution, a traffic stop can be lawful if it is

based on an officer’s reasonable mistake of law. Heien v. North Carolina,

574 U.S. 54
, 67 (2015); see 
id.
 at 69–70 (Kagan, J., concurring) (elaborating

on which mistakes of law are “reasonable”).           However, as Cahill notes,

Pennsylvania courts have held that a mistake of law, “reasonable or

otherwise,” cannot support a warrantless stop. Commonwealth v. Rachau,

670 A.2d 731, 735
 (Pa. Cmwlth. 1996).3
____________________________________________


3 Based on the disposition of this case, we do not resolve the apparent tension

between Heien and Rachau.

       Analysis of Cahill’s argument depends on the history of the relevant

statute, case law, and legislation. At the time of the stop in this case, the

statute at issue provided:

       (b) Obscuring plate.--It is unlawful to display on any vehicle a
       registration plate which:

              (1) is so dirty as to prevent the reading of the number or
              letters thereon at a reasonable distance;

              (2) is obscured in any manner which inhibits the proper
              operation of an [automated enforcement or electronic toll
              collection system];

              (3) is otherwise illegible at a reasonable distance or is
              obscured in any manner; or

              (4) is obscured, covered or otherwise obstructed in a
              manner which inhibits the visibility of the issuing jurisdiction
              at a reasonable distance.

75 Pa.C.S. § 1332(b) (effective Aug. 4, 2017, through Nov. 2, 2022)

(emphasis added).4

       On August 23, 2022, this Court held as a matter of first impression that

Section 1332(b)(3) “unambiguously prohibits the obstruction or concealment

of any portion of a registration plate, including the address to our

commonwealth’s tourism website.” Ruffin, 
282 A.3d at 804
. We explained

____________________________________________


4 Prior law also prohibited displaying an obscured registration plate.     Act of
April 29, 1959, P.L. 58, No. 32, § 504. Notably, the 1959 Vehicle Code defined
an “Obscured Registration Plate” as one on which “the characters . . . are not
legible” from 50 feet away in daylight. Id. § 102. The 1976 Vehicle Code did
not retain this definition, providing instead: “It is unlawful to display on any
vehicle a registration plate which is so dirty as to prevent the reading of the
number or letters thereon at a reasonable distance or is otherwise illegible at
a reasonable distance or is obscured in any manner.” Act of June 17, 1976,
P.L. 162, No. 81, § 1, as amended, 75 Pa.C.S. § 1332(b) (emphasis added).

                                           -7-
J-S26037-24



that the statute “unambiguously pertains to any partial covering of a

Pennsylvania license plate.” Id. Consequently, under this Act, a police officer

had probable cause to stop a vehicle that had a license plate frame obscuring

the tourism website information on the bottom of the registration plate. Id.

       On November 3, 2022, the Governor approved Act 112, which amended

Section 1332(b) and added a rule of construction to allow for the use of frames

around registration plates.5 The statute now provides:

       (b) Obscuring plate.--It is unlawful to display on any vehicle a
       registration plate which:

              (1) is so dirty as to prevent the reading of the number or
              letters thereon at a reasonable distance;

              (2) is illegible, obscured, covered or otherwise obstructed in
              any manner which inhibits the proper operation of [an
              automated enforcement or electronic toll collection system];

____________________________________________


5 The remarks of Senator Scott Martin signal the legislative intent:


       Mr. President, this amendment also includes language from my
       Senate Bill No. 1357, which protects Pennsylvania drivers from
       the recent Commonwealth Court [sic] decision that effectively
       made license plate frames illegal in Pennsylvania. That decision
       not only put an incredible amount of Pennsylvanians at risk for
       being pulled over for simply having a frame around their plates
       from their local car dealer or favorite sports team, but it also put
       an unreasonable expectation on law enforcement to consistently
       apply the ruling. This legislation would clarify the statute to make
       it clear: only the necessary identifiable information of the plate is
       needed to be visible. It also outright bans the use of tinted covers
       on license plates that have caused enforcement issues for
       automated plate readers and law enforcement statewide.

2022 Pa. Legislative Journal—Senate 1129 (Oct. 25, 2022).



                                           -8-

            (3) is illegible, obscured, covered or otherwise obstructed in
            any manner at a reasonable distance;

            (4) is illegible, obscured, covered, or otherwise obstructed
            in any manner which inhibits the visibility of the issuing
            jurisdiction at a reasonable distance; or

            (5) has a tinted plate cover.

      (b.1) Construction.--Nothing under subsection (b) shall be
      construed to prohibit a vehicle from being affixed with a
      registration plate frame that minimally outlines the registration
      plate in such a manner that the registration plate’s number and
      issuing jurisdiction is identifiable by an automated enforcement
      system under subsection (b)(2) or by law enforcement.

75 Pa.C.S. § 1332(b), (b.1). Except for the addition of subsection (b)(5), the

legislature directed that the change “shall take effect immediately.” Act of

Nov. 3, 2022, P.L. 1734, No. 112, § 10.

      We hold that a subsequent amendment to a law does not negate the

existence of probable cause under the law in effect at the time of a police

interaction. In determining whether to stop a suspect for violating a law, an

officer can and should rely on authoritative court rulings interpreting that law.

Doing so is not a mistake of law, even if the legislature later changes the law.

This flows from the function of the judiciary in our system of government.

      Courts possess “the power, the duty and the responsibility of

interpreting . . . all legislation.” Stander v. Kelley, 
250 A.2d 474, 482
 (Pa.

1969); see Pa. Const. art. V, § 1 (vesting “judicial power” in the courts).   “In

construing a statute, the court’s interpretation is considered to be a

declaration of the applicable law as enacted by the legislature.” Babcock &

Wilcox Co. v. Workmen’s Comp. Appeal Bd., 
437 A.2d 778, 780
 (Pa.



                                      -9-
J-S26037-24



Cmwlth. 1981) (citation omitted). Such a decision becomes “the law of the

Commonwealth” until it is overruled or the statute is amended. Randt v.

Abex Corp., 
671 A.2d 228
, 232 n.3 (Pa. Super. 1996) (citing Baker v. Aetna

Cas. & Sur. Co., 
454 A.2d 1092
 (Pa. Super. 1982)); see In re Opperman’s

Estate, 
179 A. 735, 736
 (Pa. 1935) (holding that a court’s construction of a

statute “must stand, until the Legislature declares otherwise”).

      True, subsequent legislation can show that the legislature intends for a

law to be applied differently. Courts interpreting statutes must “ascertain and

effectuate the intention of the General Assembly.” 1 Pa.C.S. § 1921(a). A

prompt change to the text of a statute can rebut the presumption that a court’s

“interpretation was in accordance with the intent of the Legislature.”

Commonwealth v. Willson Prods., Inc., 
194 A.2d 162, 167
 (Pa. 1963).

      Nevertheless, legislation is generally prospective. See Rose Corp. v.

Workers’ Comp. Appeal Bd., 
238 A.3d 551
, 559 (Pa. Cmwlth. 2020) (en

banc) (“[S]tatutes must be given prospective effect only, unless the statute

includes clear language to the contrary.”). Our legislature has provided: “No

statute shall be construed to be retroactive unless clearly and manifestly so

intended by the General Assembly.”         1 Pa.C.S. § 1926.     Notably, “new

provisions [of a statute] shall be construed as effective only from the date

when the amendment became effective.” 1 Pa.C.S. § 1953. Therefore, if the

General Assembly has not indicated that a new section of a statute should be

applied retroactively, then prior decisions interpreting the statute remain valid

for cases arising prior to the new section’s enactment. See 
Randt, supra.

                                     - 10 -
J-S26037-24



       Here, our Ruffin decision interpreting Section 1332(b)(3) remained

effective on the day Trooper Fornwalt stopped Cahill.         When the General

Assembly later added a provision to permit certain registration plate frames,

75 Pa.C.S. § 1332(b.1), it directed that the addition “shall take effect

immediately.” Act of Nov. 3, 2022, P.L. 1734, No. 112, § 10. The General

Assembly did not manifest an intent for the provision to be retroactive, i.e.,

to be applied prior to approval by the Governor. This Court’s interpretation of

the unambiguous statutory text thus remained binding, mandatory authority

across the Commonwealth until the additional provision went into effect.

Trooper Fornwalt made no mistake of law and properly relied on our holding

to find probable cause that Cahill violated the law by displaying a registration

plate with “any” covering.6 Consequently, the traffic stop was valid, and the

trial court did not err by denying suppression. Cahill’s first challenge fails.

       In his remaining issues, Cahill challenges the sufficiency of the evidence

to sustain his convictions for DUI and resisting arrest. We apply the following

standard:

       We must determine whether the evidence admitted at trial, and
       all reasonable inferences drawn therefrom, when viewed in a light
       most favorable to the Commonwealth as verdict winner, support
       the conviction beyond a reasonable doubt. Where there is
       sufficient evidence to enable the trier of fact to find every element
       of the crime has been established beyond a reasonable doubt, the
       sufficiency of the evidence claim must fail.

____________________________________________


6 The Commonwealth argues, independently of our holding in Ruffin, that
Cahill’s license plate cover violated Section 1332. Because Ruffin was the
law of Pennsylvania at the time of the stop, we need not analyze this further.

                                          - 11 -
J-S26037-24


      The evidence established at trial need not preclude every
      possibility of innocence and the fact-finder is free to believe all,
      part, or none of the evidence presented. It is not within the
      province of this Court to re-weigh the evidence and substitute our
      judgment for that of the fact-finder. The Commonwealth’s burden
      may be met by wholly circumstantial evidence and any doubt
      about the defendant’s guilt is to be resolved by the fact finder
      unless the evidence is so weak and inconclusive that, as a matter
      of law, no probability of fact can be drawn from the combined
      circumstances.

Commonwealth v. Mobley, 
14 A.3d 887
, 889–90 (Pa. Super. 2011) (quoting

Commonwealth v. Mollett, 
5 A.3d 291, 313
 (Pa. Super. 2010)).

      As to DUI, Cahill alleges that the Commonwealth failed to prove his guilt

because there was no evidence of erratic driving, no chemical testing of his

blood or the purported marijuana in his car, and no expert testimony that he

was impaired as a result of drug use. Cahill argues that he was able to drive

safely, as he was acquitted of the three moving violations.

      The statutory section charged here provides:

      An individual may not drive, operate or be in actual physical
      control of the movement of a vehicle under any of the following
      circumstances:

                                 

      (2) The individual is under the influence of a drug or combination
      of drugs to a degree which impairs the individual’s ability to safely
      drive, operate or be in actual physical control of the movement of
      the vehicle.

75 Pa.C.S. § 3802(d)(2). This section “requires only proof that the driver was

under the influence of a drug or a combination of drugs to a degree that the

ability to [safely] drive is impaired.” Commonwealth v. Tarrach, 
42 A.3d 342, 345
 (Pa. Super. 2012). It “does not require that any amount or specific


                                     - 12 -

quantity of the drug be proven.” Commonwealth v. Hutchins, 
42 A.3d 302, 307
 (Pa. Super. 2012).

       We recently explained that “impairment evidence should be drawn from

the totality of the factual circumstances,” including direct and circumstantial

evidence. Commonwealth v. Nestor, 
314 A.3d 863, 874
 (Pa. Super. 2024)

(citing Commonwealth v. Spence, 
290 A.3d 301, 309
 (Pa. Super. 2023)).

A defendant’s erratic driving, demeanor, and performance on field tests can

support a finding of impairment. See, e.g., Commonwealth v. Williamson,

962 A.2d 1200, 1204
 (Pa. Super. 2008).             Notably, this Court has found

evidence sufficient to prove impairment despite a defendant’s driving in a

controlled manner, where the defendant admitted to drinking, had bloodshot

eyes, answered questions inappropriately, and refused a blood test.        E.g.,

Commonwealth v. Gruff, 
822 A.2d 773, 782
 (Pa. Super. 2003); 
id.
 at 795–

96 (Bender, J., dissenting in part).7

       Section 3802(d)(2) does not require expert testimony to prove that a

driver’s impairment was caused by drugs, although our Supreme Court

acknowledged that such testimony “may be helpful, or perhaps even

necessary,” depending on the case. Commonwealth v. Griffith, 
32 A.3d 1231, 1238
 (Pa. 2011).         Expert testimony is necessary where there is no
____________________________________________


7 Gruff involved a provision of the Vehicle Code that prohibited driving “under

the influence of alcohol to a degree which renders the person incapable of safe
driving,” former 75 Pa.C.S. § 3731(a)(1), the predecessor to 75 Pa.C.S.
§ 3802(a)(1). A fortiori, the quantum of evidence to prove that a defendant
was incapable of safe driving can also prove that his ability to safely drive
was impaired. Compare 75 Pa.C.S. § 3802(a)(1) with id. § 3802(d)(2).

“other independent evidence of impairment.”        Commonwealth v. Gause,

164 A.3d 532, 538
 (Pa. Super. 2017) (en banc).

      The facts in Gause established the need for expert proof that a driver

was impaired due to marijuana use. Because the driver promptly pulled over

for police lights, provided his documents without fumbling, did not have

bloodshot eyes, and did not admit to recent use of marijuana, expert

testimony was needed to prove impairment. 
Id.
 However, the only evidence

of marijuana impairment was an officer’s testimony based on eyelid tremors.

Id. at 536, 539
. This Court held the testimony to be inadmissible as a lay

opinion, concluded that the error was not harmless, and found the remaining

evidence to be insufficient to sustain the driver’s conviction under Section

3802(d)(2). 
Id.
 at 539–40.

      Here, by contrast, the evidence was sufficient to prove that Cahill was

driving under the influence of marijuana to a degree that impaired his ability

to safely drive, without the need for expert testimony.        Trooper Fornwalt

observed Cahill cross the white fog line while driving, smelled burnt marijuana,

and saw that Cahill had glassy, bloodshot eyes. Cahill said he was a Maryland

medical marijuana patient and that there was marijuana in the car. Cahill

showed signs of possible impairment during field tests by not following

directions, swaying while standing, and using his arms.        Trooper Fornwalt

testified without objection that he believed Cahill was incapable of safe driving.

This is enough to prove guilt under Section 3802(d)(2). As the trial court




                                     - 14 -
J-S26037-24



reasoned, Cahill’s performance on the field tests showed that Cahill “did not

have the coordination needed to safely drive.”

      Additionally, Cahill’s actions showed consciousness of guilt.         When

Trooper Fornwalt approached him, Cahill had a freshly lit cigarette.         While

Trooper Fornwalt prepared a search warrant for a blood draw, Cahill

repeatedly banged his head against the wall, causing such a disturbance that

the trooper never finished the warrant. The trial court could infer that Cahill

knew he was impaired by marijuana when he tried to mask the smell of

marijuana and prevent a blood draw that would show the presence of

marijuana.

      Therefore, despite Cahill’s substantially controlled driving, the totality of

the evidence was sufficient to establish impairment. Cahill’s challenge to his

DUI conviction fails.

      Finally, Cahill contends that the evidence was insufficient to sustain his

conviction for resisting arrest. He asserts that his arrest was unlawful and

that his actions at the barracks did not injure any of the troopers who tried to

control him.

      The statute provides: “A person commits a misdemeanor of the second

degree if, with the intent of preventing a public servant from effecting a lawful

arrest or discharging any other duty, the person creates a substantial risk of

bodily injury to the public servant or anyone else, or employs means justifying

or requiring substantial force to overcome the resistance.” 18 Pa.C.S. § 5104.

This offense requires proof that a public servant was effecting a lawful arrest

                                      - 15 -
J-S26037-24



or discharging a legal duty “other than arrest,” which the defendant intended

to prevent. See Commonwealth v. Karl, 
476 A.2d 908, 911
 (Pa. Super.

1984).8     The Commonwealth does not need to establish actual injury.

Commonwealth v. Lyons, 
555 A.2d 920, 925
 (Pa. Super. 1989). Instead,

it may prove either that the defendant’s actions created a substantial risk of

serious bodily injury or that the defendant employed means justifying or

requiring substantial force to overcome the resistance.     
Id.
   For example,

evidence was sufficient where an arrestee tried to swim away in a creek,

requiring four deputy sheriffs to subdue him. 
Id.

       Here, the evidence was sufficient to sustain Cahill’s conviction for

resisting arrest. Trooper Fornwalt lawfully arrested Cahill on suspicion of DUI

and was preparing a search warrant for a blood draw.          Cahill repeatedly

banged his head against the wall, ultimately requiring six officers to restrain

him from kicking and flailing. When Cahill was being driven to the prison, an

officer had to sit in the back of the patrol vehicle and restrain Cahill’s head.

The trial court could find that Cahill, who was under a lawful arrest, acted up

to prevent the officers from acquiring a search warrant and transporting him

to the prison. Cahill’s final challenge fails.

8 Notably, the phrase “discharging any other duty” does not include police
investigation following an unlawful arrest. Commonwealth v. Karl, 
476 A.2d 908, 911
 (Pa. Super. 1984). Here, however, the police actions followed a
lawful arrest.
