OPINION

¶ 1 Following a bench trial, defendant, William P. Bishop, was found guilty but mentally ill of 

first degree murder (720 ILCS 5/9-1(a)(2) (West 2020)), a Class M felony, and guilty of aggravated 

driving under the influence (DUI) (625 ILCS 5/11-501(a) (West 2020)), a Class 4 felony. The trial 

court rejected defendant’s insanity defense, finding that he did not prove by clear and convincing 

evidence that he lacked the substantial capacity to appreciate the criminality of his conduct at the 

time of the offense. Defendant was sentenced to a total of 31 years in the Illinois Department of 

Corrections. On appeal, defendant argues that (1) the trial court erred in determining that he was 

not legally insane at the time of the offense and (2) section 11-501(a)(7) of the Illinois Vehicle
2024 IL App (2d) 230106 

- 2 - 

Code (id. § 11-501(a)(7)) violates the equal protection clause of the Illinois and United States 

Constitutions. For the reasons that follow, we disagree with both contentions and affirm. 

¶ 2 I. BACKGROUND

¶ 3 On June 9, 2020, the State charged defendant with several offenses stemming from his 

vehicular suicide attempt that resulted in the death of Jason E. Miller and great bodily harm to 

Rory J. Fiali. On September 24, 2020, a grand jury returned an amended bill of indictment charging 

defendant with 11 felony counts. 

¶ 4 On September 1, 2022, defendant filed a motion to declare section 11-501(a)(7) of the 

Vehicle Code unconstitutional. Defendant filed the same motion again on September 6, 2022. The 

Office of the Illinois State Attorney General was properly notified and deferred to the McHenry 

County state’s attorney to respond. See Ill. S. Ct. R. 19 (eff. Sept. 1, 2006). 

¶ 5 In his motion, defendant argued that subsection (a)(7) violated the equal protection clause 

of both the Illinois and United States Constitutions. In support of his motion, defendant alleged 

that similarly situated persons charged in Illinois pursuant to section 11-501(a)(7) of the Vehicle 

Code were divided, without a rational basis, into two groups: drivers who possess a Compassionate 

Use of Medical Cannabis Program Act (Medical Cannabis Act) card (registry card), allowing the 

use of medical cannabis, and drivers who do not. Defendant points out that individuals without a 

registry card are held to a per se standard, where intoxication is presumed if, within two hours of 

driving or being in actual physical control of a vehicle, an individual has a tetrahydrocannabinol 

(THC) concentration of either 5 nanograms or more of delta-9-tetrahydrocannabinol per milliliter 

of whole blood or 10 nanograms or more of delta-9-tetrahydrocannabinol per milliliter of other 

bodily substance. 625 ILCS 5/11-501.2(a)(6) (West 2020). The State is required to prove 

intoxication, regardless of THC concentration, if an individual with a valid registry card is charged 
2024 IL App (2d) 230106 

- 3 - 

pursuant to section 11-501(a)(7) of the Vehicle Code. Defendant further argues that there is no 

rational basis for this disparate treatment, as there is no comparable distinction made for alcohol 

users and there is no evidence of the legislature’s reasoning for the disparate treatment.

¶ 6 The State responded by stating that defendant’s argument fails at its inception because he 

cannot establish that he is similarly situated to the comparison group. In order to be similarly 

situated for purposes of an equal protection analysis, the groups must be alike in all relevant 

aspects. The State argued that defendant is not similarly situated to a motorist with a registry card

because, to obtain a registry card, an individual must suffer from an underlying medical condition 

and receive a medical prescription, which requires a doctor’s oversight and warnings. Even so, the 

State further argued, if any disparate treatment exists, the statute survived rational basis scrutiny 

because it is rationally related to the legitimate state interest of maintaining safe roadways. 

¶ 7 The trial court agreed with the State, noting that there is a presumption that all statutes are 

constitutional and finding that “the two subject groups in this case are not similarly situated.” The 

trial court further found that, “even if there is a similarity, there is a rational basis for the different 

classifications or for the different treatment, and accordingly *** the motion to find 501(a)(7)

[unconstitutional] is denied.”

¶ 8 Before trial, the State moved to dismiss counts II, III, V, VII, VIII, and IX of the amended 

indictment. On October 17, 2022, the case then proceeded to a bench trial on count I, of first degree 

murder (720 ILCS 5/9-1(a)(2) (West 2020)), counts IV and VI, of aggravated battery (id. § 12-

3.05(a)(1), (f)(1)), and counts X and XI, of aggravated driving under the influence brought under 

section 11-501(a)(7) of the Vehicle Code (625 ILCS 5/11-501(a)(7) (West 2020)).1

¶ 9 In the State’s case-in-chief, the State called 18 witnesses and presented two written 

stipulations that were read into the record. Only witness testimony relevant to this appeal is

summarized below.

¶ 10 Jeanne and Todd Berge, the first witnesses who arrived on scene, both testified. They 

testified that they were in a parking lot near the location of the accident on Vanderkarr Road in 

Hebron. They were standing outside of their vehicles when they heard a loud bang. They ran 

towards the noise and saw two vehicles: a van turned over on its side and another vehicle behind 

it. Jeanne testified that she called 911. The call was admitted into evidence as People’s exhibit 2. 

Jeanne and Todd both testified that they were able to speak to defendant. Jeanne said that defendant 

was able to get out of his vehicle by himself and was appropriately responsive to questions. Todd 

also testified that defendant was able to get out of his vehicle by himself and commented to him 

that he “just looked down at [his] radio.” After that interaction, neither Jeanne nor Todd had any 

further contact with defendant.

¶ 11 Gail Hall was also called as a witness for the State. She testified that, on the day of the 

accident, she was driving home and came upon the scene. She pulled over to help. She testified 

that she spoke to defendant and he seemed dazed. She asked him to come sit in her car until 

emergency personnel arrived on scene, and he obliged. Once in her vehicle, she was able to 

converse with defendant. She asked defendant what his name was and where he lived. He 

IV was aggravated by virtue of defendant’s use of a deadly weapon (namely, a vehicle). Count VI

was aggravated, as Fiali suffered great bodily harm as a result. Count X, one of the aggravated 

DUI counts, was aggravated because it resulted in the death of Miller. Count XI, the other 

aggravated DUI count, was aggravated because it resulted in great bodily harm to Fiali.
2024 IL App (2d) 230106 

- 5 - 

responded that his name was Bill and he lived in Chicago. She then asked him if he was hurt, but

he began to mumble and did not engage in any further meaningful conversation with her. Hall 

testified that she stayed with defendant for approximately 10 to 15 minutes until first responders 

arrived on scene. Once defendant was with first responders, Hall left the scene.

¶ 12 Lloyd Laufer, a firefighter and paramedic who responded to the accident, also testified. He 

testified that he spoke with defendant on the scene. Laufer asked defendant if he was okay, and 

defendant responded that he was fine. Laufer testified that, based on his quick assessment of 

defendant, he believed that defendant was talking fine and had no visible injuries. Laufer also 

testified that defendant told him to check on the other individuals involved in the accident. After 

that brief conversation, Laufer had no other contact with defendant. 

¶ 13 Jason Novak, a deputy with the McHenry County Sheriff’s Office, testified that he 

responded to the accident. When he arrived, several emergency vehicles were already on scene. 

Novak made contact with defendant. Novak testified that he observed defendant to have a red, 

swollen injury to the right side of his face and fresh blood on his forearm. Defendant also seemed 

“kind of out of it.” Novak asked defendant for his information, and defendant was able to respond 

appropriately. Novak testified that defendant was speaking clearly and for the most part was 

responsive to his questions. He then asked defendant about the accident. Defendant responded that 

he was driving westbound on Vanderkarr Road and that the accident was his fault. Novak followed 

up by asking how the crash occurred. Defendant started to talk about the radio. Novak then asked 

defendant if he had crossed the center portion of the roadway. Defendant responded with a blank 

stare. After this, medical personnel came to assess defendant and Novak had no further interaction 

with defendant.

¶ 14 Zachary Ignoffo testified that he was a firefighter paramedic with the Wonder Lake Fire 

Department. On the day of the accident, he was dispatched to the scene at Vanderkarr Road. He 

was one of the paramedics who medically assessed defendant while on scene. Ignoffo testified that 

he asked defendant if he had any injuries. Defendant responded, but his response was delayed. 

Defendant told Ignoffo that he had abdominal and lower back pain. Ignoffo also asked defendant

if he had lost consciousness at any point. Defendant responded that he was not sure if he lost 

consciousness. Ignoffo asked if defendant remembered the accident, and defendant responded that 

he did not. Ignoffo asked if defendant had been wearing a seatbelt, and defendant responded that 

he had. Ignoffo testified that this answer was consistent with the lower abdominal injuries that 

defendant exhibited. Ignoffo also asked defendant about any medication or alcohol and drug use. 

Defendant responded that the only medication he was on was melatonin and that he had used 

marijuana. When asked when had last used marijuana, defendant did not answer. Ignoffo testified 

that defendant was generally responsive to questions. However, when he was asked what caused 

the accident, defendant responded that he was very deep in thought. Defendant made this statement 

approximately 15 times during transport. Ignoffo diagnosed defendant with an altered mental 

status. Once the ambulance arrived at Northwestern Medicine McHenry Hospital (Northwestern 

McHenry Hospital), care of defendant was handed off to the hospital staff and Ignoffo had no 

further contact with defendant.

¶ 15 Dr. Steven Singh testified that he was a general surgeon at Northwestern McHenry 

Hospital. He treated defendant after the accident. Dr. Singh testified that defendant reported that 

he was driving his car, that he wanted to kill himself, and that he drove his car into another vehicle 

on the highway. Defendant also reported mild to moderate pain in his abdomen, but no other 

significant pain or injury. Dr. Singh performed a physical examination on defendant and kept him 
2024 IL App (2d) 230106 

- 7 - 

overnight for observation. Dr. Singh testified that part of the reason defendant was kept overnight 

was due to his suicidal ideation. Throughout his interaction with defendant, Dr. Singh did not have 

any issues communicating with defendant. 

¶ 16 Joan Rembacz, a registered nurse at Northwestern McHenry Hospital, was also called as a 

witness for the State. On the day of the accident, she was called to assist in the emergency room 

department. She testified that she met with defendant in the emergency room. She described his 

demeanor as very quiet and anxious. When she and one of the other nurses asked him questions, 

he did not respond. Rembacz testified that defendant was responsive to directions he was given. 

For example, she asked him to remove his clothes and put on a gown. Defendant was able to 

comply. She also testified that, in her 40 years of experience as a nurse, she has had occasion to 

see actively psychotic patients. She did not believe defendant to be actively psychotic, nor did she 

believe he was catatonic. Rembacz testified that she was present when the police interviewed 

defendant and that defendant was more responsive to their questions than he was to hers. She also 

testified that defendant spoke about the radio giving him ideas and wanting to end his life. 

¶ 17 Andrew Thomas, a sergeant with the McHenry County Sheriff’s Office, testified that he 

was a member of the major crash investigation unit. On the day of the accident, he responded 

directly to the hospital to begin his investigation. Thomas testified that he spoke with defendant 

after he had read to defendant the traffic crash “Warning to Motorists” and defendant provided a 

blood and urine sample. Thomas’s conversation with defendant was recorded and was admitted 

into evidence as People’s exhibit 9. Thomas testified that defendant stated that he had seen the 

oncoming truck, there was nothing in his lane that required him to leave his lane, he had to end his 

life or it was the end of life, and he purposely crossed the center line. When asked if he had 

consumed any drugs or alcohol, defendant responded that he had consumed two beers the night 
2024 IL App (2d) 230106 

- 8 - 

before the accident and that he had used his THC vape pen within the last 24 hours. Thomas 

testified that defendant, throughout the interview, would fidget with his hands. He also seemed 

hesitant and measured with his answers. Overall, defendant was cooperative. Thomas testified that 

he was present for part of defendant’s subsequent interview with Deputy Trent Raupp. 

¶ 18 Thomas was received as an expert in accident reconstruction. Thomas testified that, 

utilizing multiple different methods, he was able to determine the speed of the vehicles at impact. 

He used data from both vehicles’ event data recorder and a Monte Carlo simulation to determine 

impact speed. As to defendant’s vehicle, Thomas testified that, five seconds prior to impact, 

defendant was travelling approximately 64 miles per hour. Defendant continued to increase his 

speed until, 0.2 seconds before the crash, he reached a top speed of approximately 84 miles per 

hour. Thomas also testified that the victims’ vehicle was steering to the right and braking up until 

the point of impact. Defendant’s vehicle was steering to the left and accelerating.

¶ 19 Raupp, a detective with the McHenry County Sheriff’s Office, was also called as a witness 

for the State. On the day of the accident, he responded to Northwestern McHenry Hospital to 

conduct an interview with defendant. This interview was recorded and was admitted as People’s 

exhibit 24. Raupp testified that defendant was cooperative and answered, or attempted to answer, 

every question that was asked of him. At some point in the interview, defendant began to cry. 

Raupp testified that defendant said that he heard instructions coming from the radio. When Raupp 

repeated that back to him, defendant corrected him and said that it was not the radio that told him, 

it was the thoughts in his own head. Defendant also told Raupp that his goal with the crash was to 

take his own life. After the interview concluded, Raupp had no further contact with defendant. The 

State called two other witnesses and then rested.

¶ 20 Defendant then proceeded with his case-in-chief. He called two of his treating psychiatrists, 

Dr. Iyad Alkouri and Dr. Elizabeth McMasters, and two experts, Dr. Carl Wahlstrom and Dr. 

Stafford Henry. 

¶ 21 Dr. Alkouri was a psychiatrist with Northwestern Medicine who treated defendant after the 

accident. He testified that, upon defendant’s admission to the inpatient psychiatric unit, he had 

defendant undergo a psychiatric interview. This involved an assessment of defendant, discussion 

with medical staff, and a review of defendant’s medical records. After completion of this interview, 

Dr. Alkouri concluded that defendant was in a manic episode where he was not in complete touch 

with reality. Dr. Alkouri testified that he reached this conclusion because defendant exhibited 

pressured speech, euphoria, and an illogical chain of thoughts. Dr. Alkouri described pressured 

speech as “the rhythm of it is way too fast for other people to even comprehend what the person is 

saying.” He testified that he concluded defendant was euphoric because defendant did not appear 

to comprehend the gravity of the accident. Dr. Alkouri also testified that he determined defendant’s 

chain of thoughts was not logical because he kept referring to the accident as “part of a *** game 

or kind of a peril existence.” He also referred to the accident as “part of a dare from voices in his 

mind at that time that were telling him that nothing really bad is going to happen or that he is being 

dared to do it and being pressured to just do it.” Dr. Alkouri testified that he diagnosed defendant 

with a manic episode. This diagnosis was for the time of treatment and not retroactive to the time 

of the accident. Dr. Alkouri also testified that he considered the potential effect of defendant’s 

cannabis and alcohol use and concluded that the symptoms defendant was displaying were out of 

proportion for what any of the substances may have caused. 

¶ 22 Dr. Alkouri testified that he started defendant on a treatment plan for bipolar disorder. 

Defendant remained at the acute psychiatric unit at Northwestern McHenry Hospital for about 
2024 IL App (2d) 230106 

- 10 - 

three weeks, receiving treatment. Dr. Alkouri testified that he did not believe defendant was ever 

transferred to the general psychiatric unit. Throughout defendant’s treatment, he made very slow 

progress. Even at the point defendant was discharged, Dr. Alkouri did not believe he was fully 

recovered. Dr. Alkouri also testified that he did not see any signs that defendant was malingering, 

i.e., making up his symptoms. 

¶ 23 On cross-examination, Dr. Alkouri testified that he would recommend against bipolar 

patients self-medicating with marijuana, as it can exacerbate bipolar symptoms, including mania. 

He also testified that, although he kept malingering in the back of his mind while treating 

defendant, he did not conduct any psychological testing to accurately assess for it. Dr. Alkouri 

testified that defendant, when talking about the accident, provided an explanation for why it 

happened and seemed to immediately grasp that it was not the right thing to do. 

¶ 24 Defendant then called Dr. McMasters, a psychiatrist with Northwestern Medicine, as his 

next witness. McMasters testified that, in her role as attending psychiatrist, she treated defendant 

in May 2020. Over the course of the two-week period defendant was her patient, she met with 

defendant personally approximately nine times. She diagnosed him with bipolar mania with 

psychosis, presenting with severe symptoms. She testified that she observed defendant being very 

well-groomed with appropriate hygiene, although he was restless with difficulty focusing and an 

air of superiority. On cross-examination, Dr. McMasters also testified that she had some 

reservations about defendant knowing what he had done; he did not express any concern for the 

victims and instead was focused on “how expensive this is going to be.” She further testified that, 

in addition to the bipolar diagnosis, she also diagnosed defendant with severe cannabis use 

disorder, which exacerbated his bipolar symptoms. 
2024 IL App (2d) 230106 

- 11 - 

¶ 25 Next, defendant called his two expert witnesses: Dr. Whalstorm and Dr. Henry. Dr. 

Wahlstrom, a psychiatrist board certified by the American Board of Psychiatry and Neurology in 

general psychiatry and forensic psychiatry, testified first. He testified that he had experience as an 

expert witness; he could not give a number as to how many times he had testified as an expert, 

because he has been doing it for so long. Dr. Wahlstrom testified that the defense had retained him 

to prepare a written report regarding defendant. At the time of trial, he had invoiced defense 

counsel $60,137. 

¶ 26 Dr. Wahlstrom met with defendant twice in preparation of his report—once in person for 

31⁄2 hours and once by phone for half an hour. He also testified that he interviewed defendant’s 

mother, defendant’s therapist, and defendant’s current treating doctor in preparation for his report. 

Additionally, he reviewed numerous documents and recordings, including copies of police reports, 

recorded interviews with defendant, and defendant’s medical records.

¶ 27 During the in-person meeting, Dr. Wahlstrom administered 11 surveys to defendant to 

analyze his mental condition and sanity at the time of the accident. Dr. Wahlstrom testified that 

the survey results were significant for indicating moderate bipolar disorder and mild major 

depressive disorder. Dr. Wahlstrom also spoke with defendant about his history of mental illness 

and then focused on the time period in and around the accident. Dr. Wahlstrom testified that he 

learned from defendant that he had a history of bipolar disorder and some history of alcohol and 

marijuana use, as well as a prior hospitalization for suicidal ideation. He also testified that, in the 

days preceding the accident, defendant started exhibiting bipolar symptoms, such as loss of sleep, 

rapid or racing thoughts, feeling disorganized, and problems focusing. 

¶ 28 Dr. Wahlstrom testified that defendant stated that, on the day of the accident, he woke up 

anxious, confused, and fearful. He got into his car to head to his family’s home to discuss an issue 
2024 IL App (2d) 230106 

- 12 - 

with his father. During the drive, he began to experience a lot of paranoid thoughts and fear that 

he was in trouble and being monitored. His thoughts became more and more disoriented. During 

a radio interview with Howard Stern and David Spade, defendant began to believe that the 

interview included him and that Stern and Spade were speaking directly to him. Dr. Wahlstrom

testified that this was a delusion, or idea, of reference—a fixed false belief that something in the 

environment is specifically pertaining to you. Defendant also talked to Dr. Wahlstrom about 

command hallucinations. Defendant said he felt agitated, like he immediately needed to end his 

life. He also felt as though he was receiving command hallucinations telling him to play chicken 

with the approaching car. 

¶ 29 Dr. Wahlstrom testified that he diagnosed defendant with bipolar disorder with psychotic 

features. He also testified that it was his opinion that defendant suffered from a very serious mental 

disorder at the time of the accident (namely, bipolar), such that “he was not able to step back and 

really perceive the reality of the situation and was unable to appreciate *** the wrongfulness of 

criminality of his conduct.” 

¶ 30 Dr. Henry was defendant’s other expert witness. He testified that he is a triple boardcertified psychiatrist, with certifications in general psychiatry, addiction psychiatry, and forensic 

psychiatry. He has been working in the field of forensic psychiatry since the early 1990s and has 

testified as an expert in the field of forensic psychiatry several hundred times. Dr. Henry testified 

that he was initially retained by the State, and he was not retained to prepare a report but rather to 

conduct an evaluation; after the evaluation, he was asked to draft a report. Dr. Henry testified that 

the State compensated him $14,000. The defense then retained Dr. Henry to testify at trial. 

¶ 31 Dr. Henry testified that he reviewed defendant’s medical records, defendant’s police 

reports, police interviews with defendant, some of defendant’s social media postings, and 
2024 IL App (2d) 230106 

- 13 - 

recordings of phone calls from the county jail between defendant and his mother. He also met with 

defendant for 71⁄2 hours. 

¶ 32 During the interview, Dr. Henry learned that defendant had a long history of cannabis and 

alcohol use and occasional cocaine use. Defendant also self-reported interchanging periods of 

mania and depression dating back to 2016. Defendant described having experienced psychotic 

symptoms, such as hallucinations, ideas of reference, grandiosity, hyper-religiosity, and increased 

goal-directed activity.

¶ 33 Dr. Henry testified that defendant described his mental state the night before the accident 

as overwhelmed. Defendant was anxious, having difficulty sleeping, and experiencing ideas of 

reference. On the morning of the accident, defendant described himself as irritable and 

overwhelmed with racing thoughts and anxiety. He also said he was hearing voices. 

¶ 34 Defendant told Dr. Henry that, as he was driving along I-90/I-94, he was listening to an 

interview with Howard Stern and David Spade and believed that they were speaking to him. 

Defendant described it as if they had posed questions to him. Dr. Henry testified that he would 

describe these symptoms as ideas of reference.

¶ 35 Dr. Henry testified that, throughout the interview, defendant seemed rehearsed. Certain of 

defendant’s responses seemed pulled directly from the Diagnostic and Statistical Manual of Mental 

Disorders, Fifth Edition (DSM-5). His responses did not seem genuine and authentic. Some of his 

answers also were not consistent with answers given to other medical and mental health care

providers, as indicated in his medical records. For example, defendant reported only occasional 

cocaine use to Dr. Henry, but defendant’s medical records indicate that he had relayed heavy 

cocaine use.
2024 IL App (2d) 230106 

- 14 - 

¶ 36 Dr. Henry further testified that he diagnosed defendant with bipolar disorder, alcohol 

dependence in sustained remission, cannabis dependence in sustained remission, cannabis abuse 

in sustained remission, other substance abuse in sustained remission, and narcissistic personality 

disorder. He further opined that defendant was insane at the time of the accident. The defense then 

rested.

¶ 37 The State called Dr. Edward Mahoney, a clinical psychologist, as its sole witness in

rebuttal. At the time of his testimony, he was working as a transplant psychologist with Advocate 

Christ Medical Center, but he had experience in forensic psychology dating back to when he was 

working on his doctorate degree. He also worked for the Federal Bureau of Prisons as a forensic 

psychologist and then went on to work as a forensic psychologist in private practice. He has

testified as an expert witness in forensic psychology approximately 80 times. In terms of the instant 

case, Dr. Mahoney testified that, although he had not interviewed defendant personally, he had 

reviewed a plethora of records in order to reach his opinion, including a copy of the indictment, 

the protective order pursuant to the Health Insurance Portability and Accountability Act, two 

audiotapes of defendant’s interviews with detectives on May 18, 2020, medical records from One 

Medical, forensic reports submitted by Dr. Henry and Dr. Wahlstrom, copies of all incident reports 

prepared by officers of the McHenry County Sheriff’s Office, recordings of county jail phone calls 

made by defendant, copies of medical records from St. Alexis Medical Center, copies of behavioral 

records prepared by psychiatric nurse practitioner Nimat Acorede, copies of medical records from 

Rush Hospital, copies of medical records from Northwestern McHenry Hospital, copies of medical 

records from Northwestern McHenry Hospital’s psychiatric unit, a YouTube video of defendant
2024 IL App (2d) 230106 

- 15 - 

dated June 15, 2021, a YouTube interview of David Spade by Howard Stern broadcast on May 18, 

2020,2 and progress notes and e-mails between defendant and therapist Ryan Higgins. 

¶ 38 When asked why he chose not to interview defendant, Dr. Mahoney responded, “there are 

times that you do not interview the defendant.” Some factors Dr. Mahoney considered in making 

the decision not to interview defendant included the period of time that had passed since the 

incident, how many experts had already issued reports, and the number of records that were

available for review. Dr. Mahoney testified that, because a significant amount of time had passed 

since the incident and because of the multiple experts already involved and the sheer volume of 

records for review, he determined that a personal interview was unnecessary. Dr. Mahoney also 

noted that in the most recent interview defendant had undergone, he seemed rehearsed in his

responses. According to Dr. Mahoney, these rehearsed responses are common the farther away 

one gets from the incident, but they limit the amount of helpful information that can be obtained 

from a defendant in an interview setting. 

¶ 39 Dr. Mahoney testified that, after an extensive review of all the records, he diagnosed 

defendant with bipolar I disorder, manic with psychotic features; severe cannabis use disorder; and 

severe alcohol use disorder. He further testified that, although defendant had met the first prong of 

the insanity defense, he did not meet the second, for several reasons. First, cannabis and alcohol 

use had an effect on defendant’s mental illness. Cannabis specifically exacerbates bipolar 

symptoms, including suicidal ideations. Defendant also has a history of suicidal ideation coupled 

with cannabis use dating back to 2013. Second, Dr. Mahoney did not believe that defendant was 

experiencing command hallucinations at the time of the accident; rather, he was experiencing 

delusions of reference. There was no indication of a command hallucination in the immediate 

2The interview defendant was listening to on the radio at the time of the incident. 
2024 IL App (2d) 230106 

- 16 - 

aftermath of the accident. Defendant brought up command hallucinations much later while he was 

in the hospital. Dr. Mahoney testified that, with delusions of reference, an individual is still able 

to use his or her own judgment and reasoning and still maintains the ability to direct his or her own 

behavior. He also noted that, even with a command hallucination, an individual does not have to 

respond to it. Third, defendant was suicidal at the time of the accident. Dr. Mahoney determined 

this based on interactions defendant had with officers on the scene as well as interviews with the 

other experts. Defendant expressed that he was extremely stressed and had had suicidal thoughts 

in the days leading up to the accident. Fourth and finally, defendant demonstrated goal-directed 

behavior up until the accident. He was able to drive a car, wake up, get himself dressed, and buy 

himself breakfast. He didn’t leave his house hastily; rather, he packed his things and put them in 

the car.

¶ 40 Dr. Mahoney testified that an individual can be actively psychotic and still be legally sane; 

a bipolar diagnosis with active psychosis does not automatically render an individual legally 

insane. Dr. Mahoney testified that, even with defendant’s bipolar diagnosis, it was still his opinion 

that defendant was legally sane at the time of the accident: “[d]ue to the self-ingestion *** of 

cannabis and alcohol, it created and exacerbated symptoms of his bipolar disorder. Depression was 

one of those symptoms that exacerbated which caused him to become suicidal and on the day of 

the offense he attempted to commit suicide.”

¶ 41 After Dr. Mahoney’s testimony, the State rested and the parties proceeded to closing 

arguments. The defense, prior toclosing arguments, renewed defendant’smotion to declare section 

11-501(a)(7) of the Vehicle Code unconstitutional. The trial court then took the matter under 

advisement and continued the case to November 7, 2022, for decision. 
2024 IL App (2d) 230106 

- 17 - 

¶ 42 On November 7, 2022, the trial court incorporated its prior findings sustaining the 

constitutionality of section 11-501(a)(7) of the Vehicle Code and found defendant guilty of both 

counts of aggravated DUI (counts X and XI) and guilty but mentally ill of both counts of 

aggravated battery (counts IV and VI) and the single count of first degree murder (count I). In 

doing so, the trial court also found that defendant had failed to prove by clear and convincing 

evidence that he is not guilty by reason of insanity. In making this finding, the trial court stated as 

follows:

“The question of Defendant’s sanity and mental illness are questions of fact. Both 

sides correctly have argued that pursuant to the criminal code, a person is not criminally 

responsible for conduct if at the time of such conduct, as a result of mental disease or 

mental defect, he lacks substantial capacity to appreciate the criminality of his conduct.

*** 

There is no dispute that at the time of the events in question that Mr. Bishop was 

suffering from a mental disease or defect.

* * * 

While the State challenges the affect [sic] of the Defendant’s condition, it does not 

meaningfully argue that Mr. Bishop was not suffering from a mental disease or defect at 

the time of the incident. The question, then, is whether the Defendant has proven, by clear 

and convincing evidence, that because of this mental disease or defect he lacked the 

substantial capacity to appreciate the criminality of his conduct. While not solely 

dispositive, the starting point of this analysis is the expert testimony.” 

¶ 43 The trial court then robustly discussed each of the three testifying experts, finding each

credible and ultimately concluding that the expert testimony resulted in “an evidentiary tie” and 
2024 IL App (2d) 230106 

- 18 - 

that defendant’s experts alone did not meet the burden of proof. The trial court moved on to discuss 

the lay testimony that was based on observations made shortly before or after the crime, 

referencing the testimony of eight different lay witnesses who each observed defendant shortly 

after the crime. The trial court concluded by stating: “Based upon the whole of the evidence, parts 

of which have been recited in this narrative, the Court cannot and does not find that the Defendant 

has proven, by clear and convincing evidence, the affirmative defense of insanity.” 

¶ 44 Defendant filed a motion to reconsider the finding of guilty, arguing that the expert 

testimony, his treating physicians’ testimony, and the lay testimony established his affirmative 

defense of insanity by clear and convincing evidence. On December 22, 2023, the trial court denied

that motion. The matter proceeded to sentencing on January 26, 2023. The trial court vacated the 

conviction of count X under the one-act, one-crime doctrine.3 It also merged count IV into count 

VI and then vacated the conviction of count VI under the one-act, one-crime doctrine.4 Defendant 

was then sentenced to 24 years on count I (first degree murder) and 7 years on count XI (aggravated 

DUI), to run consecutively. Defendantfiled a motion to reconsider the sentence, which was denied 

on March 16, 2023. This timely appeal followed.

3Count X, one of the aggravated DUI counts, was aggravated because the offense resulted 

in the death of Miller, as did the offense charged in count I, first degree murder. Thus, the one-act, 

one-crime doctrine was implicated. Similarly, counts IV, VI, and XI all involved the injury to Fiali, 

and the one-act, one-crime doctrine was again implicated.

4The trial court explained that the sentence was imposed on count XI, as opposed to count 

VI, because, even though count XI charged a lower-class felony, the offense has a longer 

sentencing range and requires an 85% sentence.

¶ 45 II. ANALYSIS

¶ 46 Defendant contends on appeal that (1) the trial court erred in determining that he was not 

legally insane at the time of the offense and (2) section 11-501(a)(7) of the Vehicle Code violates

the equal protection clause of both the Illinois and United States Constitutions. We disagree.

¶ 47 We begin our analysis with defendant’s contention that that the trial court erred in finding 

that he was not legally insane at the time of the offense. In Illinois, an individual is not criminally 

responsible for their conduct if, as a result of a mental disease or mental defect, he or she lacks the 

substantial capacity to appreciate the criminality of his or her conduct. 720 ILCS 5/6-2(a) (West 

2020). When a defendant raises the affirmative defense of insanity, the burden of proof is on the 

defendant to prove the defense by clear and convincing evidence. Id. § 6-2(e). However, the State 

still must prove each element of the charged offense or offenses beyond a reasonable doubt. Id.

Whether a defendant was sane at the time of an offense is generally a question for the trier of fact. 

People v. Plackowska, 2020 IL App (2d) 171015, ¶ 48 (citing People v. McDonald, 329 Ill. App. 

3d 938, 946 (2002)). A trial court’s determination of sanity will not be disturbed unless it is against 

the manifest weight of the evidence. People v. Urdiales, 225 Ill. 2d 354, 428 (2007) (citing People 

v. Johnson, 146 Ill. 2d 109, 128-29 (1991)). “A finding is against the manifest weight of the 

evidence only if the opposite conclusion is clearly evident or if the finding itself is unreasonable, 

arbitrary, or not based on the evidence presented.” People v. Deleon, 227 Ill. 2d 322, 332 (2008). 

¶ 48 It is undisputed that defendant suffered a mental disease or defect. Defendant’s insanity 

defense turned on whether, because of that mental disease or defect, he was unable to appreciate 

the criminality of his conduct. Our analysis is therefore focused on this question. 

¶ 49 Defendant argues that the trial court should not have given any weight to Dr. Mahoney’s 

testimony and instead should have relied on defendant’s two experts and accordingly found him 
2024 IL App (2d) 230106 

- 20 - 

legally insane. He argues specifically that (1) Dr. Mahoney’s testimony was confused and 

contradictory, (2) Dr. Mahoney is biased and ignored defendant’s command hallucinations, and

(3) Dr. Mahoney violated Rule 9.01 of the Ethical Principles of Psychologists and Code of Conduct 

of the American Psychological Association (APA) (hereinafter APA Code). See Am. 

Psychological Ass’n, Ethical Principles of Psychologists and Code of Conduct (2017), https://

www.apa.org/ethics/code/ethics-code-2017.pdf [https://perma.cc/M84U-XREX]. None of these 

arguments are compelling. 

¶ 50 First, defendant contends that Dr. Mahoney’s testimony was confused and contradictory 

and, therefore, the trial court should not have given it any weight. In support of this, defendant 

cherry-picks singular quotes from Dr. Mahoney’s testimony, out of context. However, it is 

important to view Dr. Mahoney’s testimony as a whole. For example, defendant states in his brief 

that “Dr. Mahoney did believe that Mr. Bishop suffered from psychosis, which was ‘a break from 

reality.’ ” While this is in part an accurate summation of Dr. Mahoney’s testimony, defendant 

conveniently neglects to acknowledge the statement immediately after: “You know, it’s a break 

from reality, but you have to look at the data. Again, as I testified before, psychosis doesn’t mean 

somebody is not aware of the wrongfulness of their actions.” In particular, defendant takes issue 

with Dr. Mahoney’s testimony regarding defendant’s cannabis consumption. He states that Dr. 

Mahoney claimed defendant did not meet the second prong of the insanity defense because of 

“volitional self-ingestion of cannabis and alcohol” but failed to explain how the influence of 

cannabis or alcohol diminished the veracity of an insanity defense. Again, viewing Dr. Mahoney’s 

testimony in context, there was sufficient explanation. Dr. Mahoney, as part of his multi-factored 

analysis, noted that defendant’s cannabis or alcohol use exacerbated his depression, causing 
2024 IL App (2d) 230106 

- 21 - 

defendant to become suicidal and attempt suicide. Defendant was still aware of the wrongfulness 

of his actions, despite the influence of cannabis or alcohol. 

¶ 51 Viewing Dr. Mahoney’s testimony in proper context, it is not confused and contradictory 

as defendant asserts. Instead, it is rooted in reliable data that is reasonably relied upon by 

psychologists in forming opinions. See supra ¶¶ 38-40. 

¶ 52 In claiming that Dr. Mahoney’s testimony was confused and contradictory, defendant also 

states that Dr. Mahoney was “the lone doctor who disagreed” with defendant’s experts. This is in 

essence a numerosity argument: that because he presented more experts supporting his position, 

they were more credible and the trial court erred in not finding defendant insane. This argument is 

misplaced. As the trial court aptly noted: 

“Dr. Wahlstrom and Dr. Henry were credible. So, too, however, was Dr. Mahoney. This is 

not a numerosity determination. Two witnesses testified for the defense that he was legally 

insane. One witness testified for the State that he was legally sane. The two-to-one split 

does not mean that the defendant has carried his burden.” 

If it came down to a mere numbers game, the affirmative defense of insanity would boil down to 

a contest of who could retain more experts, rather than an actual evaluation of the merits of the 

defense.

¶ 53 It is the responsibility of the trier of fact to resolve conflicts in the testimony and weigh the 

evidence; it is not our role to reweigh the evidence. People v. Sauls, 2022 IL 127732, ¶ 52. We 

will not substitute our judgment on questions involving the weight of the evidence or the credibility 

of witnesses. Id. In looking at Dr. Mahoney’s complete testimony, it is clear that the trial court’s 

finding that defendant was not legally insane was not against the manifest weight of the evidence.
2024 IL App (2d) 230106 

- 22 - 

¶ 54 Defendant’s second contention is that Dr. Mahoney is biased towards the State. Defendant, 

in his brief, states that “[Dr. Mahoney] is an experienced, paid witness ***.” Defendant further 

states that Dr. Mahoney is “blinded by his bias” in not recognizing command hallucinations in 

defendant. Ironically, defendant fails to acknowledge that both of his retained experts were 

experienced and paid witnesses (see supra ¶¶ 25, 30). In any case, it is axiomatic that bias impacts 

the credibility of a witness. Credibility determinations are solely within the province of the trier of 

fact. John Crane Inc. v. Allianz Underwriters Insurance Co., 2020 IL App (1st) 180223, ¶ 20. We 

will not disturb the trial court’s credibility findings unless they are against the manifest weight of 

the evidence. Id. Here, we cannot find that the trial court’s determination that Dr. Mahoney was a 

credible witness was against the manifest weight of the evidence. The trial court heard all of the 

evidence, including that Dr. Mahoney was paid by the State and has experience as an expert 

witness. The trial court also heard that Dr. Mahoney was an expert in forensic psychology and 

found him qualified to render an opinion on the issue of insanity. Dr. Mahoney’s opinion was also 

based on reliable data. See supra ¶¶ 37-40. 

¶ 55 Further, it is well established that a trier of fact may accept one expert’s testimony over 

another, so long as the accepted opinion is based on a credible diagnosis. Plackowska, 2020 IL 

App (2d) 171015, ¶ 49 (quoting McDonald, 329 Ill. App. 3d at 946). It follows then that a trier of 

fact may determine that conflicting expert testimony has equal weight, so long as all experts based 

their testimony on a credible diagnosis. Here, as discussed above, Dr. Mahoney’s diagnosis was 

based on credible data and was substantially similar to the diagnoses given by the other experts. 

All three experts diagnosed defendant with bipolar disorder, and both Dr. Henry and Dr. Mahoney 

also diagnosed defendant with a cannabis use disorder. Dr. Mahoney disagreed with both Dr. 

Wahlstrom and Dr. Henry that defendant was experiencing command hallucinations, but that 
2024 IL App (2d) 230106 

- 23 - 

disagreement was rooted in reliable data. See supra ¶¶ 38-40. It was not arbitrary, and therefore 

the trial court’s finding that Dr. Mahoney’s testimony was equally credible to that of Dr. 

Wahlstrom and Dr. Henry was not against the manifest weight of the evidence. 

¶ 56 It is clear that the trial court carefully considered all factors, including potential bias of 

witnesses, in reaching its conclusion that Dr. Mahoney was credible and that defendant was not 

legally insane at the time of the incident. We therefore reject this argument. 

¶ 57 Defendant’s third contention is that Dr. Mahoney violated Rule 9.01 of the APA Code. In 

his brief, defendant cites Rule 9.01(c) of the APA Code, but quotes language from Rule 9.01(b). 

Rule 9.01(b) reads as follows: 

“(b) Except as noted in 9.01c, psychologists provide opinions of the psychological 

characteristics of individuals only after they have conducted an examination of the 

individuals adequate to support their statements or conclusions. When, despite reasonable 

efforts, such an examination is not practical, psychologists document the efforts they made 

and the result of those efforts, clarify the probable impact of their limited information on 

the reliability and validity of their opinions, and appropriately limit the nature and extent 

of their conclusions or recommendations.” Am. Psychological Ass’n, supra, at 13. 

Rule 901(c) reads as follows: 

“(c) When psychologists conduct a record review or provide consultation or 

supervision and an individual examination is not warranted or necessary for the opinion, 

psychologists explain this and the sources of information on which they based their 

conclusions and recommendations.” Id.

Defendant emphasizes the fact that Dr. Mahoney did not meet with defendant personally, claiming 

that this failure both violates the APA Code and renders his opinion unreliable. We do not find 
2024 IL App (2d) 230106 

- 24 - 

that any such ethical violation occurred. The plain language of Rule 9.01(b) carves out an 

exception for the circumstance in Rule 9.01(c)—record reviews. Here, that is exactly what Dr. 

Mahoney did. He conducted a thorough record review and provided an opinion based on that. He 

explained why he thought an examination of defendant was unnecessary, and he also thoroughly

explained the sources he relied on in rendering his opinion. See supra ¶¶ 38-39. It does not appear 

as though any ethical violation has occurred. 

¶ 58 In effect, defendant here is claiming that the basis of Dr. Mahoney’s opinion is faulty, since 

he did not meet with defendant personally. However, it has been held that both doctors and 

psychiatrists testifying at trial can give an opinion without having met personally with a defendant, 

so long as that opinion is based on facts or data that are reasonably relied upon by experts in that

particular field. See Wilson v. Clark, 84 Ill. 2d 186, 194 (1981); People v. Eckhardt, 156 Ill. App. 

3d 1077, 1094 (1987) (citing People v. Newbury, 53 Ill. 2d 228, 236 (1972), and People v. Smith, 

93 Ill. App. 3d 26, 34 (1981)). The same is true of psychologists. Further, any weakness in the 

basis of an expert’s opinion goes to weight, not admissibility. People v. Comier, 2020 IL App (1st) 

170500, ¶ 83 (citing People v. Lind, 307 Ill. App. 3d 727, 739 (1999)). The trial court was not 

required to disregard Dr. Mahoney’s opinion merely because he did not meet personally with 

defendant. This is true even if Dr. Mahoney violated the APA Code. Finally, even if Dr. Mahoney’s 

failure to meet with defendant personally violated the APA Code, that violation would not compel 

a reversal in this case. 

¶ 59 As a final note, defendant consistently discusses the credibility of the experts and how the 

trial court should have found defendant’s experts more credible than Dr. Mahoney. However, that 

is not a proper argument, given the standard of review.
2024 IL App (2d) 230106 

- 25 - 

“[I]t is not sufficient that there is evidence to support defendant’s argument or even that, 

were we the trier of fact, we would have found clear and convincing proof of insanity. The 

standard by which we must review the trial court’s denial of defendant’s affirmative 

defense is whether its decision was against the manifest weight of the evidence. We will 

not substitute our judgment for the trial court’s regarding the weight of the evidence, the 

credibility of the witnesses, or the inferences to be drawn from the evidence.” People v. 

McCullum, 386 Ill. App. 3d 495, 505 (2008). 

It does not matter that defendant thinks his experts were more credible than the State’s and that 

evidence exists within the record to support his affirmative defense. Although there was conflicting 

expert testimony, there was sufficient evidence for the trial court to conclude that defendant was 

not legally insane at the time of the offense. Accordingly, we do not find that the trial court’s 

finding was against the manifest weight of the evidence. 

¶ 60 We now address defendant’s second and final contention—that section 11-501(a)(7) of the 

Vehicle Code violates the equal protection clause of the Illinois and United States Constitutions. 

Defendant claims that subsection (a)(7) violates equal protection because it treats lawful users of 

“personal cannabis” differently. Under subsection (a)(7), users without a valid registry card are 

presumed intoxicated if, within two hours of driving or being in actual physical control of a motor 

vehicle, they have a THC concentration of either 5 nanograms or more of delta-9-

tetrahydrocannabinol per milliliter of whole blood or 10 nanograms or more of delta-9-

tetrahydrocannabinol per milliliter of other bodily substance. 625 ILCS 5/11-501.2(a)(6) (West 

2020). The State must prove intoxication for users charged under subsection (a)(7) who possess a 

valid registry card, regardless of THC level. Defendant’s argument fails at its inception, as he 

cannot establish that he is similarly situated to the comparison group. 
2024 IL App (2d) 230106 

- 26 - 

¶ 61 “The constitutionality of a statute presents a question of law, which is reviewed de novo.” 

In re M.A., 2015 IL 118049, ¶ 21. Statutes are presumed to be constitutional; the party challenging 

the statute has the burden of establishing a clear constitutional violation. People v. Baker, 2020 IL 

App (2d) 181048, ¶ 9 (citing People v. One 1998 GMC, 2011 IL 110236, ¶ 20). Equal protection 

analysis is the same under both the United States and Illinois Constitutions. People v. Shephard, 

152 Ill. 2d 489, 499 (1992). The fourteenth amendment to the United States Constitution provides: 

“[N]or shall any State deprive any person of life, liberty, or property, without due process of law; 

nor deny to any person within its jurisdiction the equal protection of the laws.” U.S. Const., amend. 

XIV, § 1. Article I, section 2, of the Illinois State Constitution provides: “No person shall be 

deprived of life, liberty or property without due process of law nor be denied the equal protection 

of the laws.” Ill. Const. 1970, art. I, § 2. 

¶ 62 “Generally, equal protection requires the government to treat similarly situated people in a 

similar manner.” People v. Donoho, 204 Ill. 2d 159, 176-77 (2003). However, equal protection 

does not forbid all classifications; rather, it prevents the legislature from treating similarly situated

individuals differently. M.A., 2015 IL 118049, ¶ 25 (citing In re Derrico G., 2014 IL 114463, 

¶ 92). To be similarly situated for purposes of equal protection, individuals must be alike in all 

relevant aspects. Id. Determining if individuals are similarly situated requires an analysis of the 

purpose of the legislation at issue. Id. ¶ 26. If a party fails to show that he or she is similarly situated 

to the comparison group, the equal protection argument fails. Id.

¶ 63 Additionally, distinctions between similarly situated persons in a class can be made, so 

long as the distinction is proper. People v. Dean, 363 Ill. App. 3d 454, 463-64 (2006). For a 

nonsuspect class, as defendant concedes is the case here, rational-basis review applies. Id. at 464. 

Under rational-basis review, a statute passes constitutional muster if the statute has a rational 
2024 IL App (2d) 230106 

- 27 - 

relationship to a legitimate purpose and is neither arbitrary nor discriminatory. Donoho, 204 Ill. 

2d at 177. 

¶ 64 Our first step in the equal protection analysis is to determine if defendant, as an individual 

charged under subsection (a)(7) who used cannabis without a valid registry card, is similarly 

situated to the comparison group, cannabis users with a valid registry cards. As an initial note, 

defendant failed to provide any analysis detailing how the two groups thatsubsection (a)(7) creates 

are similarly situated. As the State remarked, the reviewing court “ ‘is entitled to have issues 

clearly defined with pertinent authority cited and cohesive arguments presented [citation], and it 

is not a repository into which an appellant may foist the burden of argument and research.’ ” In re 

Marriage of Knoll, 2016 IL App (1st) 152494, ¶ 69 (quoting Velocity Investments, LLC v. Alston, 

397 Ill. App. 3d 296, 297 (2010)). Failure to properly raise and develop an argument results in 

forfeiture of that argument. Ill. S. Ct. R. 341(h)(7) (eff. Oct. 1, 2020). 

¶ 65 Forfeiture aside, defendant’s position appears to be that lawful users of cannabis without a 

valid registry card are similarly situated to lawful users of cannabis with a valid registry card, 

because both groups can legally use cannabis for personal or recreational use, yet users without a 

valid registry card are subjected to a per se intoxication standard under subsection (a)(7) while 

users with a valid registry card are not. In order to assess whether these two groups are similarly 

situated, we must examine the relative positions of each group in light of the broad purpose and 

operation of the statute. 

¶ 66 Section 11-501 of the Vehicle Code was enacted to keep impaired drivers off the road. 

People v. Fate, 159 Ill. 2d 267, 269 (1994); People v. Minor, 2019 IL App (3d) 180171, ¶ 20.

Effective July 1, 1990, the legislature added a subsection, which prohibited driving with any 

amount of cannabis in one’s system “resulting from the unlawful use or consumption of cannabis.” 
2024 IL App (2d) 230106 

- 28 - 

Pub. Act 86-1019 (eff. July 1, 1990) (adding Ill. Rev. Stat. 1991, ch. 951⁄2, ¶ 11-501(a)(5)). This 

subsection was moved from subsection (a)(5) to subsection (a)(6) in January 1999. Pub. Act 90-

779 (eff. Jan. 1, 1999) (amending 625 ILCS 5/11-501). 

¶ 67 The Illinois legislature later enacted the Compassionate Use of Medical Cannabis Pilot

Program Act (Pub. Act 98-122 (eff. Jan. 1, 2014) (adding 410 ILCS 130/1 et seq.)), which 

authorized the use of cannabis for medical purposes. In doing so, the legislature acknowledged the 

beneficial uses of cannabis in treating certain illnesses. 410 ILCS 130/5 (West 2014). With the 

legalization of medical cannabis, section 11-501 of the Vehicle Code was also amended to account 

for the new developments in cannabis law. The following sentence was added to subsection (a)(6): 

“Subject to all other requirements and provisions under this Section, this paragraph (6)

does not apply to the lawful consumption of cannabis by a qualifying patient licensed under 

the [Medical Cannabis Act] who is in possession of a valid registry card issued under that 

Act, unless that person is impaired by the use of cannabis.” Pub. Act 98-122 (eff. Jan. 1, 

2014) (amending 625 ILCS 5/11-501(a)(6)).

Though the Medical Cannabis Act legalized cannabis for medical use, it explicitly did not permit

any individual to operate a vehicle while under the influence of cannabis. 410 ILCS 130/30(a)(5)

(West 2014). 

¶ 68 Effective July 2016, subsection (a)(7) was added to section 11-501(a) of the Vehicle Code. 

It prohibited an individual from driving or being in actual physical control of a vehicle if “the 

person has, within 2 hours of driving or being in actual physical control of a vehicle, a [THC]

concentration in the person’s whole blood or other bodily substance as defined in paragraph 6 of 

subsection (a) of Section 11-501.2 of this Code.” Pub. Act 99-697 (eff. July 29, 2016) (amending 

625 ILCS 5/11-501(a)). The newly added subsection (a)(6) of section 11-501.2 of the Vehicle 
2024 IL App (2d) 230106 

- 29 - 

Code reads as follows: “[THC] concentration means either 5 nanograms or more of delta-9-

tetrahydrocannabinol per milliliter of whole blood or 10 nanograms or more of delta-9-

tetrahydrocannabinol per milliliter of other bodily substance.” Pub. Act 99-697 (eff. July 29, 2016) 

(amending 625 ILCS 5/11-501.2). Another newly added subsection reads as follows: “If there was 

a [THC] concentration of 5 nanograms or more in whole blood or 10 nanograms or more in an 

[sic] other bodily substance as defined in this Section, it shall be presumed that the person was 

under the influence of cannabis.” Id.

¶ 69 In June 2019, the legislature enacted the Cannabis Regulation and Tax Act (Pub. Act 101-

27 (eff. June 25, 2019) (adding 410 ILCS 705/1-1 et seq.)), which legalized recreational use of 

cannabis for individuals over 21 years of age, effective January 1, 2020. In so enacting, the 

legislature found that cannabis should be regulated in a manner similar to alcohol. This act did not 

amend section 11-501(a) of the Vehicle Code. 

¶ 70 The precise issue of whether cannabis users with a valid registry card are similarly situated 

to those without was recently discussed by the Fourth District in People v. Lee, 2023 IL App (4th) 

220779. In Lee, the defendant was found guilty at a bench trial of aggravated driving under the 

influence of cannabis and was sentenced to six years in prison. Id. ¶ 1. On appeal, the defendant 

argued that section 11-501(a)(7) of the Vehicle Code violated the equal protection clause of both 

the Illinois and United States Constitutions. The appellate court disagreed, finding that cardholding medical cannabis users were not similarly situated to noncard holders because, in order to 

obtain a valid registry card, an individual must suffer from certain debilitating medical conditions 

(410 ILCS 130/10(t) (West 2020)) and have a physician’s certification (id. § 55(a)(1)). Lee, 2023 

IL App (4th) 220779, ¶ 46. 
2024 IL App (2d) 230106 

- 30 - 

¶ 71 Although recreational cannabis was illegal at the time of the accident in Lee, we find the 

Fourth District’s analysis to be instructive. Under the Medical Cannabis Act, in order to be 

registered as a qualifying patient, an individual must meet the following requirements: (1) submit 

a completed application5; (2) submit a written certification from a health care professional within 

90 days of submitting the application certifying that (a) the individual is suffering from a 

debilitating medical condition as defined by the Medical Cannabis Act and (b) the certifying health 

care professional is treating or managing treatment of that condition; and (3) pay a registry card 

fee. 410 ILCS 130/55(a) (West 2020). In certain instances, an individual may be required to 

produce medical documentation related to his or her debilitating condition. Id. § 55(a)(2).

¶ 72 Given the significant number of prerequisites in order to obtain a valid registry card, 

defendant cannot establish that he is similarly situated to individuals with a valid registry card. 

Users without a valid registry card, such as defendant, have not established any debilitating 

medical conditions or that they are receiving ongoing treatment by a health care professional.

Additionally, under the Medical Cannabis Act, users with a valid registry card are presumed to be 

engaged in the medical use of cannabis so long as the amount of cannabis they possess does not 

exceed the amount allowed by subsection (a) of section 10 of the Medical Cannabis Act. See id.

5The application requires personal information such as name, address, date of birth, last 

four digits of social security number, phone number, and e-mail address. An applicant is also 

required to provide proof of identity in the form of a state driver’s license, state ID card, passport, 

or other form. See Qualifying Patient Application Instructions, Ill. Dep’t of Pub. Health, https://

dph.illinois.gov/topics-services/prevention-wellness/medical-cannabis/patient-applicationinstructions.html (last visited Mar. 12, 2024) [https://perma.cc/ZFW4-C4PR]. 
2024 IL App (2d) 230106 

- 31 - 

§ 25(d)(1). Even if that presumption is rebutted and an individual with a valid registry card is 

deemed to be using cannabis recreationally, that does not change the fact that they are 

simultaneously receiving ongoing treatment from a health care professional. This distinguishes 

them from recreational users without a valid registry card, such that an equal protection claim fails.

¶ 73 This distinction also fits within the broad purpose and operation of the statutes at issue 

here. Section 11-501(a) of the Vehicle Code, the Medical Cannabis Act, and the Cannabis 

Regulation and Tax Act each have different legislative purposes. Section 11-501(a) of the Vehicle 

Code was enacted to keep impaired drivers off the road. Fate, 159 Ill. 2d at 269; Minor, 2019 IL 

App (3d) 180171, ¶ 20. In achieving this purpose, courts have found that per se impairment statutes 

are constitutional. See People v. Ziltz, 98 Ill. 2d 38, 42-43 (1983) (finding that statute imposing 

strict liability on drivers found to be impaired by an alcohol concentrate of 0.10% or above did not 

violate the United States Constitution). The Medical Cannabis Act legalized cannabis for medical 

use and acknowledged the benefits of cannabis when used for medical purposes. See 410 ILCS 

130/1 et seq. (West 2020). And the Cannabis Regulation and Tax Act legalized the use of cannabis 

for recreational use and found that it should be treated similarly to alcohol in the eyes of the law. 

See 410 ILCS 705/1-1 et seq. (West 2020). In order to balance those competing interests, the 

legislature deemed it appropriate to treat individuals with a valid registry card differently from 

those without a valid registry card to achieve goals of both traffic and road safety and allowing 

individuals to benefit from the medical properties of cannabis. The creation of these two groups 

helps to serve the broader purposes of the legislature, and, accordingly, valid registry cardholders 

are not similarly situated to non-cardholders. 

¶ 74 Even if the two groups were similarly situated, defendant’s argument fails because there is 

a rational basis for treating the groups differently. Defendant’s rational basis argument revolves

- 32 - 

solely around the Cannabis Regulation and Tax Act. See id. § 1-5(a). He argues that the purposes 

of the act is are to help law enforcement focus on non-cannabis crimes and so the State can generate 

revenue for social programs, but these purposes are not furthered by treating valid registry card 

holders differently from non-cardholders under section 11-501(a)(7) of the Vehicle Code. 

¶ 75 Defendant’s reliance solely on the Cannabis Regulation and Tax Act is misplaced. The 

statute at issue here, section 11-501(a)(7) of the Vehicle Code, is designed to keep impaired drivers 

off the road. Fate, 159 Ill. 2d at 269; Minor, 2019 IL App (3d) 180171, ¶ 20. This purpose has 

been held to be a legitimate State interest (Fate, 159 Ill. 2d at 271), and courts have routinely 

upheld the constitutionality of similar per se impairment statutes. See, e.g., Ziltz, 98 Ill. 2d at 42-

43. When the Medical Cannabis Act was passed, the legislature explicitly carved out an exception 

for valid registry cardholders in subsection (a)(7). This exception is not arbitrary, as it is rationally 

related to achieving the legitimate State interests of both traffic and road safety and allowing 

individuals to benefit from the medical properties of cannabis. 

¶ 76 The legislature’s treatment of cannabis is also similar to the legislature’s treatment of 

prescription medication. Driving after consuming prescription medication is not illegal; rather, a 

lawful user of prescription medication may drive so long as his or her prescribed medication does 

not render him or her incapable of driving. People v. Vente, 2012 IL App (3d) 100600, ¶ 12 (citing 

People v. Rodriguez, 398 Ill. App. 3d 436 (2009)). Similarly, here, a lawful user of cannabis with 

a valid registry card may drive after consuming cannabis, so long as it does not render him or her 

incapable of driving. This satisfies both purposes of traffic and road safety and allowing 

individuals to benefit from the medical properties of cannabis.

¶ 77 As defendant failed to establish that he is similarly situated to the comparison group and 

that section 11-501(a)(7) does not have rational relationship to a legitimate purpose that is neither 

arbitrary nor discriminatory, we reject defendant’s second contention. 

¶ 78 There is no denying the tragedy of this case. It is clear from the record that defendant was 

suffering from a mental illness at the time of the incident. However, this does not absolve 

defendant; he must bear the consequences of his actions.
