Panel JUSTICE HYMAN delivered the judgment of the court, with opinion.

Presiding Justice Pierce concurred in the judgment and opinion.

Justice Gordon specially concurred, with opinion.

 OPINION 

¶ 1 Plaintiff Raymond Berke fell in the vestibule of an apartment building where he and his 

wife were staying with friends. A doorman heard but did not see Raymond fall, and there were 

no eyewitnesses. Raymond sustained spinal injuries rendering him quadriplegic. He has no 

memory of the incident. 

¶ 2 Raymond brought a premises liability claim against the building owner and the 

management company, alleging the vestibule area, and the stairs and doorway in particular, 

were improperly designed and maintained and were the direct and proximate cause of his 

injuries. Raymond’s wife brought loss of consortium claims against both defendants. 

¶ 3 Defendants moved for summary judgment, and the trial court entered judgment in their 

favor. The Berkes argue that they presented sufficient admissible evidence to support their 

prima facie case of premises liability, precluding summary judgment. They also contend that 

the trial court erred in striking parts of their expert witness affidavits, submitted in support of 

their response to defendants’ summary judgment motion and that the court should have granted 

their motion to cite supplemental authority. 

¶ 4 We affirm. The Berkes presented no evidence other than speculative assertions through 

expert affidavits that Raymond fell because defendants created and maintained a condition 

exposing him to an unreasonable risk of injury. Further, the trial court did not abuse its 

discretion in denying the motion to cite supplemental authority. 

¶ 5 BACKGROUND 

¶ 6 In November 2012, Raymond and Carol Berke, who live in California, stayed with friends 

in a luxury 12-story co-op apartment building. Trust No. 2450 Lakeview Avenue Trust owns 

the building; Wolin-Levin, Inc., a property management company, manages and maintains it. 

Toward the back of the building is a west exit from which one can get to the parking garage. 

The west exit has an exterior building door on top of a threshold with a landing that opened to 

a stairwell with three steps that led to an exterior door to the outside. The threshold was 71⁄2 

inches high on the interior side and 21⁄4 inches high on the exterior side. The landing was 101⁄2 

inches deep. When leaving through the west exit, a person has to walk through the exterior 

building door, onto or over a 71⁄2-inch threshold, step down 21⁄4 inches onto the 101⁄2-inch 

landing, and then up the three stairs out through the exterior door. According to the Berkes, the 

height and the depth of the threshold and the depth of the landing violated code and industry 

standards and constituted a tripping hazard. They also assert that the building door violated 

several building codes and standards because it opened inward and had an automatic closure 

system that caused it to close too quickly and prevented a person from passing through it 

safely. The Berkes contend the tripping hazard created by the threshold and door was 

exacerbated by the lack of any warning signs. 
- 3 - 

¶ 7 On November 2, Raymond and Carol left the apartment building through the west exit and 

went to their car, which was in the parking garage. Carol forgot her cell phone in the apartment, 

and Raymond went back to get it. Dan Cooney, the building’s doorman, escorted Raymond to 

the apartment and back. Cooney said he walked with Raymond toward the west exit but 

Raymond waved him off, indicating he did not need Cooney to open the door for him. Cooney 

saw Raymond go through the door and saw the door close behind Raymond. Cooney returned 

to his desk, located a few feet from the exit. Moments later, Cooney heard a noise he described 

as a “kunk,” went to the west exit, and found Raymond face down on the ground, with his head 

on the second stair leading out the exit door. Cooney said he did not hear Raymond trip and 

does not know what caused him to fall. 

¶ 8 When Cooney reached Raymond he saw that his eyes were closed and clenching. He 

thought that Raymond might have been trying to move or get up but was unable to do so. 

Cooney asked a coworker for help, called 911, and then went out to the parking garage to tell 

Carol that her husband had an accident. When Carol went back inside she saw Raymond lying 

on the ground with his head on the first step below the landing and his feet two to five inches 

from the interior door. She said Raymond was not face down but was leaning toward the right 

with the right side of his face on the stair. He had abrasions on his chin and nose. Later, 

additional abrasions were found on Raymond’s knees. An ambulance took Raymond to St. 

Joseph Hospital. It was later determined that Raymond was quadriplegic. 

¶ 9 Raymond, who did not regain consciousness until after surgery, has no memory of his fall. 

When asked what he remembered from that morning, Raymond said “I remember going to the 

car in the garage. And that’s all that I remember. *** I have no recollection after going to the 

garage the first time. *** And I have no recollection of anything for the next three days.” He 

said he did not know what caused his fall and could not recall anything about the west exit that 

may have caused him to fall. 

¶ 10 The Berkes sued defendants for negligence and loss of consortium. (They also sued St. 

Joseph Hospital, numerous medical providers, and the City of Chicago; those claims are not a 

part of this appeal.) The Berkes specifically alleged that defendants were negligent in (1) 

allowing the premises to remain improperly designed, (2) allowing the premises to remain 

improperly lit, (3) failing to ensure the premises were free from debris, (4) allowing a hand 

railing to remain in improper condition, (5) allowing the layout of the premises to “remain 

contra to applicable safety hazards,” (6) allowing the layout of the premises to remain in an 

unsafe condition, (7) allowing the layout of the premises to remain in disrepair, and (8) failing 

to maintain the premises. The Berkes further allege that “one or more” of these acts of 

negligence proximately caused Raymond’s injuries. 

¶ 11 Defendants filed a motion for summary judgment, arguing that the Berkes have not 

demonstrated that defendants breached their duty of care and cannot demonstrate that the 

defendants’ conduct was the proximate cause of Raymond’s injuries. In response, the Berkes 

contended defendants had a duty to invitees to maintain the premises in a reasonably safe 

condition. They also asserted that the west exit’s threshold was a tripping hazard and that a 

reasonable jury could conclude that Raymond tripped and fell as a natural and probable 

consequence of defendants’ negligent failure to inspect and maintain the premises. The Berkes 

cited to at least four pieces of evidence that make this conclusion reasonable and more 

probable than any other explanation: (1) the threshold violated building codes and industry 

standards and was a tripping hazard; (2) the proximity of Raymond’s feet to the tripping 
- 4 - 

hazard; (3) the abrasions to Raymond’s face and knees, which are consistent with a forward 

trip and fall; and (4) the absence of other causes within reasonable contemplation. 

¶ 12 The Berkes’ response included affidavits from Arnold Siegel, an accident 

reconstructionist; Gregory Wisniewski, an architect; and Dr. Kenneth Corre, an emergency 

room physician. 

¶ 13 Siegel asserted, based on his inspection of the premises, review of materials produced in 

discovery, and measurements of the doorway and vestibule, that the western entrance to the 

building constituted an unwarned tripping hazard, that Raymond encountered that tripping 

hazard “because he was found on or past the tripping hazard in the direction of egress travel,” 

and that “[t]he natural and probable consequence of an individual encountering a tripping 

hazard is that he will more likely than not trip and fall.” Thus, he concluded that the 

“unreasonably dangerous condition of the doorway more likely than not caused Raymond 

Berke to fall and trip forward with motion.” Wisniewski similarly opined that “[t]he 

unreasonably dangerous threshold and unreasonably dangerous door and closure system more 

likely than not caused Dr. Berke to fall.” He further asserted that “[d]efendants were negligent 

and caused Dr. Berke to trip and fall by failing to perform a competent inspection, detect and 

remedy the defects present at or around the west entrance of the building.” Dr. Corre asserted, 

based on his review of Raymond’s medical records, that no acute or chronic medical condition 

or illness caused him to collapse, lose his balance, or fall and his abrasions were “most likely 

the result of a prone forward fall resulting from a trip to a reasonable degree of medical 

probability.” 

¶ 14 During a hearing on defendants’ summary judgment motion, the Berkes’ attorney asked to 

cite Stuhlmacher v. Home Depot U.S.A., Inc., 774 F.3d 405 (7th Cir. 2014), as additional 

authority. The circuit court stated that because it is a products liability case, “[i]t’s an entirely 

different standard. So I’m not considering [it].” After hearing arguments, the circuit court 

granted summary judgment in defendants’ favor.

¶ 15 In so ruling, the court granted the defendants’ motion to strike those parts of the Berkes’ 

three experts’ affidavits offering an opinion as to what caused Raymond to fall. The court 

stated that the experts’ assertions that Raymond fell because of a property defect depended on 

inadmissible and speculative evidence and were not compliant with Illinois Supreme Court 

Rule 191 (eff. Jan. 4, 2013). The court struck that portion of Siegel’s affidavit asserting that the 

“natural and proper consequence of an individual encountering tripping hazard is that he will 

more likely than not trip and fall” as predicated on what may have happened, thereby resting on 

inadmissible conjecture. On Wisniewski’s assertions—that “[t]he unreasonable dangerous 

threshold and unreasonably dangerous door and closure system more likely than not caused 

Dr. Berke to fall”—the trial court considered them “speculative on their face.” As for Dr. 

Corre’s affidavit, the court concluded it “would permit virtually any plaintiff from avoiding 

summary judgment because it asserts that any healthy person would not trip and fall unless it 

was caused by a dangerous condition.”

¶ 16 The trial court then entered summary judgment because Raymond failed to establish 

proximate cause. Relying on Strutz v. Vicere, 389 Ill. App. 3d 676 (2009), the trial court held 

that, as in Strutz, no one saw Raymond fall, and the court “cannot utilize expert evidence 

linking a defect of the property to a fall when there was no admissible evidence linking the 

defect to the fall.” The trial court also stated that “[u]nlike Strutz, there was a witness who only 

heard the fall, and it is unrefuted that Mr. Cooney did not hear anything else, which is evidence 
- 5 - 

that the door did not hit plaintiff or that plaintiff tripped over the thresholds.”

¶ 17 ANALYSIS 

¶ 18 Experts’ Affidavits

¶ 19 Before turning to the trial court’s summary judgment order, we address the decision to 

strike parts of the experts’ affidavits setting forth an opinion on the cause of Raymond’s fall. 

The Berkes contend the affidavits meet all of the requirements of Illinois Supreme Court Rule 

191, and thus, the trial court erred in striking them. 

¶ 20 Under Rule 191, an affidavit offered in support of or in opposition to a motion for summary 

judgment must (1) be made on the personal knowledge of the affiants, (2) set forth with 

particularity the facts on which the claim is based, (3) attach sworn or certified copies of 

documents the affiant relied on, and (4) consist of facts admissible in evidence, not 

conclusions. Ill. S. Ct. R. 191(a) (eff. Jan. 4, 2013). 

¶ 21 An affidavit submitted in the summary judgment context serves as a substitute for 

testimony at trial. Fooden v. Board of Governors of State Colleges & Universities, 48 Ill. 2d 

580, 587 (1971). The trial court may not consider evidence that would be inadmissible at trial 

when assessing a motion for summary judgment. Safeway Insurance Co. v. Hister, 304 Ill. 

App. 3d 687, 691, (1999). Therefore, strict compliance with Rule 191(a) is necessary “to insure 

that trial judges are presented with valid evidentiary facts upon which to base a decision.” 

Solon v. Godbole, 163 Ill. App. 3d 845, 851 (1987). Affidavits in opposition to motions for 

summary judgment must consist of facts admissible in evidence as opposed to conclusions, 

and conclusory matters may not be considered in opposition to motions for summary 

judgment. Id. Additionally, “[a]n expert’s opinion is only as valid as the reasons for the 

opinion.” Hudson v. City of Chicago, 378 Ill. App. 3d 373, 400-01 (2007). Expert opinions 

relying on speculation, conjecture, or guess as to what the witness believed might have 

happened are inadmissible. Id. at 401 (citing Modelski v. Navistar International 

Transportation Corp., 302 Ill. App. 3d 879, 886 (1999)). When experts (i) fail to take into 

consideration a party’s actions, (ii) base their opinions on facts not in evidence, (iii) base their 

opinions on what might have happened, and (iv) ignore significant factors, the court will reject 

the experts’ opinions as mere speculation and conjecture. Damron v. Micor Distributing, Ltd., 

276 Ill. App. 3d 901, 909 (1995). A motion to strike affidavits in conjunction with the granting 

of summary judgment is reviewed de novo. Collins v. St. Paul Mercury Insurance Co., 381 Ill. 

App. 3d 41, 46 (2008). 

¶ 22 Because all three expert witness affidavits are speculative, the trial court did not err in 

striking them. 

¶ 23 Arnold Siegel, an accident reconstructionist, averred that: 

“Passing through a doorway is an action that is so common and familiar that 

individuals typically look forward towards the passage route or door handle and not 

downward; creating a severely high risk of tripping and falling when obstacles obstruct 

the passage route. Dr. Berke was likely looking forward towards the passage route or 

door handle, he did not expect to encounter the 71⁄2 x 21⁄4 x 121⁄2 inch threshold, causing 

him to trip and fall forward. Raymond Berke was found with his feet 2-5 inches from 

the door or the threshold and his head on the 2nd step of the stairway. *** Raymond 

Berke encountered the severe tripping hazard because he was found on or past the 
- 6 - 

tripping hazard in the direction of egress travel. The natural and probable consequence 

of an individual encountering a tripping hazard is that he will more likely than not trip 

and fall. 

 * * *

 The unreasonably dangerous condition of the doorway more likely than not caused 

Raymond Berke to trip and fall forward with motion. 

 * * *

 For the aforementioned reasons, it is my opinion that [the] threshold and fast heavy 

closing door at issue were unreasonably dangerous, that Defendants were negligent in 

failing to comply with regulations and standards that put them on notice of those 

dangerous conditions, and that Raymond Berke was caused to trip and fall by that 

threshold as he passed through the doorway with its fast closing and heavy door.”

¶ 24 Siegel’s opinion as to what caused Raymond to fall turns on nothing more than conjecture. 

He presumes Raymond was “likely” looking forward because that is what people “typically” 

do. He also asserts Raymond was not expecting to encounter the threshold, despite the fact that 

he had crossed it twice on his way out of and back into the building only minutes before his 

fall. Raymond himself could not shed light on this question because he had no recollection of 

his fall or what may have been its cause. 

¶ 25 Similarly speculative is Wisniewski’s opinion on the cause of the fall. Wisniewski set out 

measurements of the doorway and rear exit and the tests he performed on the door, showing 

that it closed too quickly under industry standards. Then, he opined that Raymond might have 

caught his foot on the threshold as the door was closing and concluded that “[t]he unreasonably 

dangerous threshold and unreasonably dangerous door and closure system more likely than not 

caused Dr. Berke to fall.” No evidence shows that the door closed on Raymond as he was 

walking through. Indeed, Cooney, the doorman, testified that he saw the door close after 

Raymond walked through it. 

¶ 26 The Berkes contend, however, that Siegel’s and Wisniewski’s affidavits should not have 

been stricken because a causation expert may draw and rely on factual inferences as the basis 

for his or her opinions. They also contend that “an expert’s causation testimony is not 

inadmissible simply because it is ‘couched in terms of probabilities or possibilities based upon 

certain assumed facts.’ ” Donaldson v. Central Illinois Public Service Co., 313 Ill. App. 3d 

1061, 1076 (2000) (quoting McKenzie v. SK Hand Tool Corp., 272 Ill. App. 3d 1, 8 (1995)). 

Plaintiff cites Murphy v. General Motors Corp., 285 Ill. App. 3d 278, 284 (1996), for support. 

In Murphy, the plaintiffs alleged that Palos Auto & Glass had negligently performed repairs on 

the driver’s seat of a vehicle that later slid backward off its track and injured the plaintiffs. 

Following the accident, another repair shop disposed of the seat and its frame. The trial court 

struck the affidavit of plaintiffs’ expert and granted summary judgment for Palos, finding that 

“ ‘[w]ithout the seat frame this case is thrown into a speculative arena.’ ” Id. at 281. The 

appellate court reversed. Although plaintiffs’ expert did not inspect the actual seat involved in 

the incident, he reviewed the seat’s design and specifications, as well as the depositions of 

mechanics at both repair shops. The record contained enough circumstantial evidence to 

support the expert’s opinions that Palos’ work caused the seat to collapse and that Palos should 

have replaced the seat instead of repairing it. The court found that these fact questions were for 

the jury, making summary judgment for Palos improper. Id. at 283. 
- 7 - 

¶ 27 The Berkes argue that as in Murphy, Siegel and Wisniewski made inferences based on 

known facts and that the jury should be allowed to weigh those facts. We disagree. First, unlike 

this case, in Murphy, the record contained sufficient circumstantial evidence to support the 

experts’ opinions that defendant’s work on the car caused the seat to collapse. For instance, the 

owner of the shop that repaired the seat before the accident said in his deposition that GMC 

standards were not followed and the owner of the auto repair business where the car was taken 

after the accident gave a deposition testifying that when he examined the seat, he noted that the 

seat frame had been welded, which indicated to him that it had previously broken and that he 

noticed a “bend” in the seat frame located within two inches of the weld. From these 

statements, the court concluded, a jury could infer that the seat was not in the condition in 

which GMC delivered the car. Id. 

¶ 28 The main parties deposed, Raymond, Carol, and Cooney, offer no circumstantial evidence 

from which to infer what happened, as they did not witness or remember it. Wisniewski asserts 

that Cooney admitted the door could close as someone falls through it and that Raymond may 

have caught his foot on the threshold as the door was closing. But that is not what Cooney said 

he saw happen. Cooney testified, “What I did see was [Raymond] went through [the door] and 

the door closed behind him.” Thus, Wisniewski’s opinion is not based on known facts but 

rather on what could have happened. (Cooney testified, “I couldn’t tell you particularly how he 

stepped on the door step.”) In the absence of facts supporting Siegel’s and Wisniewski’s 

conjectures, the trial court did not err in striking those parts of their affidavits. 

¶ 29 Lastly, Dr. Corre’s affidavit asserted, based on his review of the materials, including 

records from St. Joseph Hospital, that it is “more likely than not, no acute chronic medical 

condition/s and/or illness/es caused Raymond Berke to collapse, lose his balance or fall on 

11/2/10 ***. Simply put, the materials do not support that any acute medical condition caused 

his fall. Raymond Berke’s abrasions to his legs and face are more likely the result of a prone 

forward fall resulting from a trip to a reasonable degree of medical certainty.” Like the other 

experts’ affidavits, Dr. Corre speculates. While Dr. Corre may be correct in asserting that 

Raymond’s fall was not caused by a medical condition, it does not necessarily follow that it 

was caused by his having tripped. Because this portion of his affidavit was based on 

speculation, the trial court did not err in striking it. 

¶ 30 Summary Judgment 

¶ 31 Summary judgment is appropriate when the pleadings, depositions, and admissions on file, 

together with the affidavits, show an absence of any genuine issue of material fact and 

entitlement to judgment as a matter of law. 735 ILCS 5/2-1005(c) (West 2014); Northern 

Illinois Emergency Physicians v. Landau, Omahana & Kopka, Ltd., 216 Ill. 2d 294, 305 

(2005). In determining whether a genuine issue of material fact exists, the trial court strictly 

construes the pleadings, depositions, admissions, and affidavits against the movant and 

liberally in favor of the opponent. Adames v. Sheahan, 233 Ill. 2d 276, 295-96 (2009). The 

party moving for summary judgment need not prove its case or disprove the nonmovant’s case. 

Kellman v. Twin Orchard Country Club, 202 Ill. App. 3d 968, 974 (1990) (quoting Waite v. 

Chicago Transit Authority, 157 Ill. App. 3d 616, 619 (1987)). Rather, the movant is entitled to 

summary judgment by demonstrating the absence of a genuine issue of material fact. Id.

(quoting Waite, 157 Ill. App. 3d at 619). The nonmoving party may defeat a claim for summary 

judgment by demonstrating that a question of material fact exists. Sheahan, 233 Ill. 2d at 296. 
- 8 - 

Although the nonmoving party also need not prove his or her case at the summary judgment 

stage, he or she must come forth with some evidence that arguably would entitle recovery at 

trial. Ross v. Dae Julie, Inc., 341 Ill. App. 3d 1065, 1069 (2003). We review de novo an order 

granting summary judgment. Outboard Marine Corp. v. Liberty Mutual Insurance Co., 154 Ill. 

2d 90, 102 (1992). 

¶ 32 To establish a premises liability negligence claim, the plaintiff must present sufficient 

factual evidence to establish the existence of a duty of care owed by the defendant to the 

plaintiff, a breach of that duty, and an injury proximately caused by that breach. Marshall v. 

Burger King Corp., 222 Ill. 2d 422, 430 (2006). Proximate cause is an essential element of a 

negligence claim. Bermudez v. Martinez Trucking, 343 Ill. App. 3d 25, 29 (2003). Generally, 

proximate cause presents a question of fact; however, it becomes a question of law when the 

facts alleged indicate that a party would never be entitled to recover. Id. at 29-30. Accordingly, 

a plaintiff who fails to establish the element of proximate cause has not sustained his or her 

burden of making a prima facie case and summary judgment is proper. Mann v. Producer’s 

Chemical Co., 356 Ill. App. 3d 967, 972 (2005). 

¶ 33 Proximate cause consists of two requirements: cause in fact and legal cause. Abrams v. City 

of Chicago, 211 Ill. 2d 251, 258 (2004). For a defendant’s conduct to be a “cause in fact” of the 

plaintiff’s injury, the conduct must form “a material element and a substantial factor in 

bringing about the injury.” Id. If the plaintiff’s injury would not have occurred absent the 

defendant’s conduct, then the conduct forms a material element and substantial factor in 

bringing about the injury. Id. On the other hand, “legal cause” involves an assessment of 

foreseeability and the court must consider whether the injury is of the type that a reasonable 

person would foresee as a likely result of his or her conduct. Id. 

¶ 34 To establish proximate cause, the plaintiff bears the burden of “ ‘affirmatively and 

positively show[ing]’ ” that the defendant’s alleged negligence caused the injuries for which 

the plaintiff seeks to recover. Bermudez, 343 Ill. App. 3d at 29 (quoting McInturff v. Chicago 

Title & Trust Co., 102 Ill. App. 2d 39, 48 (1968)). Liability against a defendant cannot be 

predicated on speculation, surmise, or conjecture. Mann, 356 Ill. App. 3d at 974 (citing 

Wiegman v. Hitch-Inn Post of Libertyville, Inc., 308 Ill. App. 3d 789, 795-96 (1999). Thus, the 

plaintiff must establish with “reasonable certainty” that the defendant’s acts or omissions 

caused injury. Mann, 356 Ill. App. 3d at 974. 

¶ 35 The plaintiff may establish proximate cause through circumstantial evidence. Id. That is, 

causation may be established by facts and circumstances that, in the light of ordinary 

experience, reasonably suggest that the defendant’s negligence operated to produce the injury. 

Id. It is not necessary that only one conclusion follow from the evidence. Id. But, a fact cannot 

be established through circumstantial evidence unless the circumstances are so related to each 

other that it is the only probable, and not merely possible, conclusion that may be drawn. 

Wiegman, 308 Ill. App. 3d at 796. Indeed, where the proven facts demonstrate that the 

nonexistence of the fact to be inferred appears to be just as probable as its existence, then the 

conclusion is a matter of speculation, conjecture, and guess and the trier of fact cannot be 

permitted to make that inference. Mann, 356 Ill. App. 3d at 974. 

¶ 36 The Berkes argue Raymond’s injury occurred when he tripped over the threshold at the 

west exit because it was unreasonably high and violated numerous building codes and industry 

standards. No direct evidence of proximate cause exists, so the Berkes argue that (i) the 

expert’s affidavits, (ii) the height of the threshold, (iii) the position in which Raymond was 
- 9 - 

found, (iv) the abrasions on Raymond’s knees and face, (v) the absence of any other reason for 

the fall, (vi) a prior fall in the vestibule, and (viii) testimony that Raymond was walking 

normally and appeared healthy on the day of the accident permit the inference that the cause 

was the high threshold and the door closing too fast. In response, defendants argue that 

reasonable jurors could not base a verdict on one identifiable cause over another without 

guessing as to whether the condition of the threshold and door caused Raymond to fall. 

¶ 37 We agree with defendants. The Berkes have not “affirmatively and positively shown” with 

“reasonable certainty” that Raymond fell because he tripped over the threshold or was 

propelled forward by a door that closed too quickly. No direct evidence shows why Raymond 

fell, because he has no recollection and, although Cooney, the doorman, heard Raymond hit 

the ground, he did not see or hear what made him fall. Moreover, the Berkes cannot establish 

causation through circumstantial evidence. Although a trier of fact could infer that Raymond, 

who was observed to be walking at a rapid pace, tripped over the threshold or was propelled 

forward by the door, it is equally likely that a jury could conclude that he fell for reasons 

unrelated to the condition of the premises. 

¶ 38 Two cases, Strutz v. Vicere, 389 Ill. App. 3d 676 (2009), and Kellman v. Twin Orchard 

Country Club, 202 Ill. App. 3d 968 (1990), are instructive. In Strutz, plaintiff’s husband 

sustained injuries when he allegedly slipped and fell on the back staircase at a two-flat 

apartment building owned by defendants. No one saw him fall. The plaintiff testified that when 

she found her husband on the back stairs and asked what happened he said, “ ‘I fell down over 

the railing.’ ” Strutz, 389 Ill. App. 3d at 677. The husband died a few weeks later, and plaintiff 

brought a negligence and wrongful death action against the defendants. In an affidavit, the 

plaintiff’s expert architect averred that the steps were dangerous because they violated the City 

of Chicago building code. He opined that the stairs were unreasonably dangerous because the 

treads were too small (which made the stairs excessively steep), the tread widths were 

inadequate and uneven, the staircase was inadequately lit, the handrail in the center was too 

low, and there was no handrail on the wall side of the stairs. The trial court granted summary 

judgment in favor of the defendants. Id. at 678. 

¶ 39 The appellate court held the violations by themselves did not establish proximate cause, 

absent any evidence that the safety violations caused the injury. The court further concluded 

that the plaintiff’s statement that he “ ‘fell down over the railing’ ” did not explain the cause of 

the fall and could not create a genuine issue of material fact as to causation. Id. at 681. 

¶ 40 Likewise, in Kellman, no one witnessed the decedent’s fall. Kellman, 202 Ill. App. 3d at 

970-71. The decedent, Kellman, was taking a shower in a country club locker room when he 

fell and fractured his spine. Another club member, who was also taking a shower, heard a 

“thud” and found Kellman lying face down in the shower stall. Kellman’s family filed a 

negligence lawsuit and relied on expert testimony to establish the condition of the stall and the 

manner in which he fell. The country club moved for summary judgment, arguing that there 

were no eyewitnesses to the fall and that the plaintiff was unable to prove causation. The trial 

court granted summary judgment, and the appellate court affirmed. The court noted that none 

of the testimony addressed the issue of what caused Kellman’s fall and concluded that the mere 

possibility an unreasonably dangerous condition in the stall had caused the fall was not enough 

to establish a causal relationship between the defendant’s alleged negligence and Kellman’s 

injuries. Id. at 975.

¶ 41 As in Strutz and Kellman, no one saw Raymond fall. Even if, as the Berkes assert, the 

threshold and door created a dangerous condition, this is not sufficient to establish a causal 

connection between defendants’ alleged negligence and Raymond’s injuries. Therefore, the 

conclusion advocated by plaintiffs embraces speculation, surmise, and conjecture. See Mann, 

356 Ill. App. 3d at 974; see also Bakkan v. Vondran, 202 Ill. App. 3d 125, 131 (1990). A trier of 

fact cannot be permitted to make that inference. See Wiegman, 308 Ill. App. 3d at 795-96. The 

conclusion that the height of the threshold caused Raymond to fall formulates merely a 

possible conclusion, not a probable conclusion. See id. at 796. This is not a case in which the 

plaintiff and defendant both presented evidence of proximate cause and a jury should be called 

on to resolve the dispute. See Mann, 356 Ill. App. 3d at 974. Thus, absent direct or 

circumstantial evidence of proximate cause, the Berkes have failed to make a prima facie case 

of negligence, and summary judgment was proper. See id. at 972. 

¶ 42 We also note that the Berkes contend the west exit violated building codes and industry 

standards because the threshold was too high, the landing was too small, and the door closed 

too quickly. They assert that all of these violations created an unexpected tripping hazard, 

which was exacerbated by the lack of any warning signs. Even if, as plaintiffs assert, 

defendants breached their duty of reasonable care by failing to remove a hazardous exit, this 

does not constitute evidence of causation. Violations of an ordinance or failure to comply with 

the building code by themselves, without evidence that the violation caused the injury, do not 

establish proximate cause. Strutz, 389 Ill. App. 3d at 681. The possibility that the allegedly 

unreasonably dangerous exit caused Raymond to trip fails to provide the necessary causal 

relationship between defendants’ alleged negligence and Raymond’s injuries.

¶ 43 Absent any evidence of the cause of Raymond’s fall, there is no genuine issue of material 

fact for the trier of fact to determine. 

¶ 44 Supplemental Authority 

¶ 45 The Berkes argue the trial court abused its discretion in failing to grant their motion to cite 

Stuhlmacher v. Home Depot U.S.A., Inc., 774 F.3d 405 (7th Cir. 2014), as supplemental 

authority. In Stuhlmacher, the purchasers of a ladder brought a products liability claim against 

a home improvement store and the ladder’s manufacturer after their son sustained injuries 

when the ladder fell the first time it was used. Plaintiffs’ expert witness testified that the 

ladder’s rivets were overtightened during manufacturing, which created a weakened 

connection that would have caused the plaintiffs’ son to sense a change in the ladder’s stiffness 

and to involuntarily move his weight left, causing the ladder to tumble. The trial court struck 

this testimony as incompatible with the plaintiffs’ son’s testimony that the ladder never 

became unstable. Thus, the plaintiffs could not show a causal link between the alleged defect 

and the accident. Id. at 408. The appellate court reversed. It held that the expert’s testimony 

satisfied the relevancy standard set forth in Daubert v. Merrell Dow Pharmaceuticals, Inc., 

509 U.S. 579 (1993), because it was reliable and would assist the trier of fact in determining 

some fact at issue. Stuhlmacher, 774 F.3d at 409. Further, given the circumstances of the case, 

the court determined that the correctness of the expert’s theory involved a fact issue left for the 

jury. A jury could have found that the expert’s theory of the accident was credible and the 

plaintiff’s testimony reflected his memory of the event as it was happening. Id. Similarly, 

according to the Berkes, a jury should hear their experts’ testimony and decide whether it 

supports their argument that Raymond tripped over the threshold. 
- 11 - 

¶ 46 But, unlike in Stuhlmacher, no evidence exists as to what happened to Raymond that 

caused him to fall. Although the plaintiff in Stuhlmacher offered testimony that did not 

necessarily comport with the expert’s theory, he did recall his accident and offered his own 

version of what happened. No testimony or other evidence shows what caused Raymond to 

fall. Thus, there is no factual issue for the jury to decide, and the trial court properly denied the 

Berkes’ request to cite Stuhlmacher as additional authority. 

¶ 47 Affirmed. 

¶ 48 JUSTICE GORDON, specially concurring. 

¶ 49 I concur with the majority, but I write separately on plaintiffs' request to cite additional 

authority. I believe that a court learns about the case before them through the lawyers in their 

presentation, pleadings, and the authority they cite, and the court's independent analysis of the 

law. As a result, I do not believe it is correct for a trial judge to deny the tender of additional 

authority. In the case at bar, it appears that the court denied the cite as additional authority only 

because she was familiar with the case cited and did not find it instructive as to the facts before 

her. The act of the court in denying the cite as additional authority has no affect on the outcome 

of the trial court's decision in this case or on this appeal.
