    ORDER
    1-21-0676
    Held:             We affirm the trial court’s order granting summary judgment to defendants-
    appellees ABSS Manufacturing, Inc. and Sunset Ladder Co. with respect to
    plaintiff’s strict liability claim based on a ladder collapse. The evidence does not
    permit an inference of product defect to support plaintiff’s claim of strict liability
    because (1) there is undisputed evidence of plaintiff’s abnormal use of the ladder
    at issue and (2) plaintiff cannot show that there was no reasonable secondary cause
    of his injury.
    ¶1   In this product liability action stemming from a ladder collapse, plaintiff-appellant Carlos Pike
    appeals from the circuit court order granting summary judgment to defendants-appellees ABSS
    Manufacturing, Inc. (ABSS) and Sunset Ladder Co. (Sunset). We conclude the undisputed
    evidence could not support an inference of a manufacturing defect in the subject ladder, as the
    evidence did not show the absence of abnormal use or reasonable secondary causes of Pike’s
    injury. Accordingly, we affirm the entry of summary judgment for ABSS and Sunset.
    ¶2                                                   BACKGROUND
    ¶3   This case stems from an incident in which Pike was injured while climbing a ladder in the course
    of working to set up a trade show booth. At the time of the incident, Pike was working as a union
    carpenter for Absolute I&D (Absolute), a company that builds and installs exhibits for trade
    shows. 1 Absolute was hired to set up a booth for Red Sun Farms at the United Fresh Produce
    Association trade show at the McCormick Place convention center.
    ¶4   On June 7, 2015, Pike was working to set up the Red Farms booth with Charles Brown, an
    electrician employed by Freeman Electrical, Inc. (Freeman). Brown was tasked with installing
    wiring through “raceways” or soffit near the ceiling of the booth. In order to do so, Brown retrieved
    an 8-foot fiberglass stepladder that was owned by Freeman.
    1
    Absolute is not a party to this appeal, although it was sued as a third-party defendant in the underlying action. The
    merits of the third-party complaint are not at issue in this appeal.
    -2-
    1-21-0676
    ¶5   The ladder was manufactured in February 2013 by ABSS and subsequently sold by Sunset, a ladder
    distributor, to Freeman. It is undisputed that the ladder had a load capacity of 300 pounds, and the
    ladder was labeled as such.2 It is also undisputed that Pike weighed approximately 350 pounds at
    the time of his injury.
    ¶6   For about one hour preceding the incident, Brown used the ladder to run electrical wiring through
    a number of pre-cut “mouse holes” at various points in the booth. At one point, while he was
    standing on the ladder’s fifth step, Brown informed Pike that he was having difficulty running
    wiring through one of the “mouse holes.” Brown descended the ladder, and Pike began to climb
    it so that he could inspect the area. As he was climbing the third or fourth step, the ladder collapsed
    and Pike was injured.
    ¶7   On May 17, 2017, Pike filed a complaint naming as defendants ABSS, Sunset, Freeman, and
    Freeman Expositions. Counts I and II (which are not at issue in this appeal) alleged various
    negligent acts by Freeman and Freeman Expositions. In count III of the complaint—the only count
    at issue—Pike alleged a claim of “strict product liability” against ABSS and Sunset, as
    manufacturer and distributor of the ladder. Pike alleged that, when the ladder was placed in the
    stream of commerce, it was “in a defective and unreasonably dangerous condition in one or more
    of the following respects:
    a) the stepladder was structurally unsound and unsafe;
    b) the stepladder did not meet industry design standards;
    c) the stepladder did not meet manufacturing specifications;
    d) the stepladder failed to contain adequate warnings regarding
    weight limitations;
    2
    A label on the ladder stated that its “DUTY RATING” was TYPE 1 A” and “LOAD CAPACITY: 300 LBS.”
    -3-
    1-21-0676
    e) the materials used in the manufacture of the stepladder were
    defective;
    f) the stepladder failed when used in an intended and reasonably
    foreseeable manner.”
    Pike alleged that he was injured as a proximate result of the ladders’ “defective and unreasonably
    dangerous conditions”
    Brown and Pike’s Deposition Testimony
    ¶8     The parties conducted a number of depositions, including those of Brown and Pike. In his
    deposition, Brown testified that because he was doing electrical work for Freeman at the time of
    the incident, he was required to use a ladder provided by Freeman. On the day of the incident, he
    selected the ladder from a bin of Freeman-owned ladders. He “checked it first” and “found a
    sturdy ladder.” When asked how he checked the ladder, Brown said he opened the ladder, and its
    “stiffness” let him know that the “cross brace was good.” He did not notice any breaks or defects
    in the ladder before he began to use it.
    ¶9     For approximately one hour before Pike’s injury, Brown ascended and descended the ladder a
    number of times in the course of installing wiring through a number of mouse holes. Brown did
    not have any problems using the ladder. Brown stated that at the time, he weighed between 225
    and 230 pounds.
    ¶ 10   Shortly before Pike’s injury incident, Brown was on the ladder when he informed Pike that he was
    having difficulty running an extension cord through a mouse hole, because the hole was too small.
    Pike told him to come down so that Pike could inspect the area. Brown climbed down the ladder,
    and Pike “immediately” started up the ladder. Pike did not stop to read the labels on the ladder.
    -4-
    1-21-0676
    Brown heard cracking when Pike reached the third step of the ladder, and the “ladder just
    collapsed.” Brown did not see any cracks or damage to the ladder before Pike used it.
    ¶ 11   In Pike’s deposition, he likewise testified that Brown used the ladder for at least an hour before
    the incident, and that Brown climbed up and down the ladder without any problems. Just before
    the incident, Brown told him a “hole was too small” to run electrical cord through. According to
    Pike, Brown came down the ladder and told Pike to “go up and take a look yourself.” Pike stated
    that he “went right up the ladder to take a look.” Pike testified that he did not inspect the ladder
    before he climbed on it, because Brown had not had any problems using it: “Charlie Brown was
    on this ladder, so I did not expect this particular ladder – I guess you could say I assumed it was
    safe like all the other ladders that I’ve used over the years, especially since Charlie Brown is about
    the same size as me and had been using it all day.”
    ¶ 12   Pike recalled that as he started to go up the ladder, “it just collapsed under me” when he was at the
    third or fourth step. Pike testified that the ladder’s cross braces were down and locked in place
    before he started climbing, and that his hands were on the side rails as he began climbing. He
    denied hearing any creaking or cracking sounds before it collapsed.
    ¶ 13   Pike denied that he ever received any “formal training” on how to use ladders safely from Absolute
    or any contractor he worked for. During his deposition, Pike estimated that he weighed
    approximately 305 to 310 pounds at the time of the accident. However, the parties do not dispute
    that, according to medical records, he actually weighed approximately 350 pounds at the time of
    the incident. 3
    3
    Pike also acknowledged that he had right knee surgery in 2013, left knee surgery in 2014, and a
    laminectomy in February 2015, approximately four months before the incident. However, he
    denied that his knees were bothering him and stated that his back was “fine” at the time of the
    incident.
    -5-
    1-21-0676
    ¶ 14   Pike testified that he did not inspect the label on the ladder and did not know its duty rating before
    he climbed it:
    “Q. Were you aware of what the duty rating was on the ladder that was
    involved in your accident?
    A. No, sir.
    Q. If I told you this was the label on your ladder and that your ladder
    had an extra heavy industrial duty rating of 1A with a working load
    of 300 pounds, you would understand what I mean, right?
    A. I would understand what you mean, yes sir.
    Q. Were you aware that you weren’t supposed to load the ladder in
    excess of 300 pounds at the time you used it?
    A. No, because I didn’t know if it was a 1A or a 1AA.
    Q. Because you didn’t inspect those labels?
    A. Correct.”
    ¶ 15   Pike also testified that he did not know if he would have used the ladder, even had he seen the
    label indicating that its duty rating was 300 pounds. When asked why he might use a ladder with
    a 300-pound duty rating when he weighed more than 300 pounds, Pike responded: “ I’ve been on
    ladders for the last 30 years, I’ve never had an issue. I didn’t even know that there was a ladder on
    the show floor that couldn’t carry 300 pounds because 80 percent of the guys down there are my
    size and I’ve never seen that.”
    ¶ 16     Deposition Testimony of Bradley Becnel on behalf of ABSS and Sunset
    -6-
    1-21-0676
    ¶ 17   Bradley Becnel testified that he was the sole owner of Sunset and that he had been a “50/50”
    partner in ABBS, along with Nasir Ahmed. Ahmed unexpectedly passed away in October 2018,
    while this case was pending.
    ¶ 18   Becnel testified that he was “at the sales end” of ABSS but had little involvement with ABSS’
    manufacturing process. Becnel identified documents reflecting that in February 2013, Freeman
    ordered a number of ladders from Sunset, which were manufactured by ABSS. That order included
    the ladder involved in Pike’s injury. Becnel agreed that the labeling on the ladder involved in
    Pike’s incident indicated it was manufactured by ABSS in February 2013, and that its load capacity
    was 300 pounds.
    ¶ 19   Becnel testified that the ladder at issue used a “standard” design that had existed for many years
    before ABSS was a company. According to Becnel, “[v]irtually all ladder companies make an
    extremely similar product.”
    ¶ 20   Becnel testified that Ahmed ensured that ladders manufactured by ABSS complied with standards
    from the American National Standards Institute (ANSI) and Occupational Safety and Health
    Administration (OSHA). Becnel identified ABSS ladder testing protocols from 2004 and 2017,
    which were the only relevant testing documents ABSS had located. Becnel indicated that Ahmed
    would have known about additional testing. ABSS had searched Ahmed’s computer but had not
    found other testing documentation for 8-foot ladders. Becnel believed that ABBS had performed
    additional testing, but he lacked personal knowledge as to how often testing was done.
    ¶ 21   Becnel agreed that the ladder’s labeling indicated a load capacity of 300 pounds. Becnel testified
    that a user should not exceed the stated capacity rating for a ladder:
    “Q. Do you know [what] the capacity rating is for an extra heavy-
    duty ladder?
    -7-
    1-21-0676
    A. Yes.
    Q. What are those?
    A. 300 and 375 would both be extra-heavy duty.
    Q. Do you know what that means when it says 300 and 375 pounds?
    A. Yes, that’s the capacity that you’re not supposed to exceed.
    Q. On what?
    A. On the ladder, period.”
    ¶ 22   However, Becnel also agreed that ABSS ladders are expected to be able hold more weight than
    their stated capacity:
    “Q. Were you aware that ladders were manufactured to exceed a
    300-pound standard?
    A. Yes.
    Q. Do you know what the maximum load is on a stair for your
    ladders?
    A. Not offhand, no.
    Q. Is it fair to say there is sometimes double and triple redundancy
    built into these ladders?
    A. Yes.
    Q. So your ladders are designed to basically hold up to 900 or 1200
    pounds?
    A. Yes, absolutely.
    Q. So if a 300-pound guy walked on that ladder, it shouldn’t fail?
    -8-
    1-21-0676
    A. Yes.
    [ABSS COUNSEL] I will show an objection to walk on that ladder.
    Q. If a 375-pound guy walked on that ladder, onto that ladder, it
    should not fail?
    A. Correct.
    [ABSS Counsel]: I’ll show the same objection, but with that
    objection, form and foundations. If you understand the question, sir,
    go ahead.
    THE WITNESS: If a ladder is in good shape, it should not fail.
    Q. And your counsel brought up a good point. Let me clarify that
    question. If a ladder is properly set up; in other words, extended with
    the side locked, it’s in good shape, no other damage, a 375-pound
    person should be able to use that ladder without the ladder failing,
    correct?
    A. I would agree.
    Q. In fact, it may hold a 500-person [sic] on it if it’s properly set up
    with no damage; is that correct?
    A. Yes.
    Q. And that’s the redundancy that is built into the ladder to make it
    safer?
    A. Yes.
    Q. And you believe your ladders were made to sustain that, correct?
    A. Correct.”

    1-21-0676
    ¶ 23    Plaintiff’s Expert, John Newquist
    ¶ 24   Plaintiff retained John Newquist as an expert witness. According to his report, Newquist is an
    independent safety consultant who worked for OSHA from 1983 through 2012.
    ¶ 25   Newquist’s report indicated his view that ABSS had not complied with ANSI’s “Standard for
    Ladder Portable Reinforced Plastic Safety Requirements,” insofar as section 8.1.5 of that standard
    requires that “ ‘Design verification tests shall be conducted.’ ”
    ¶ 26   Newquist also stated that compliance with OSHA standards “would have prevented access to the
    unsafe ladder and the resulting fall.” Specifically, Newquist cited the regulation which requires
    that a self-supporting portable ladder must be capable of supporting “At least four times the
    maximum intended load, except that each extra heavy-duty type 1A metal or plastic ladder shall
    sustain at least 3.3 times the maximum intended load.” 29 CFR 1926.1053(a)(1).
    ¶ 27   Elsewhere in his report, Newquist stated that “The collapse of the ladder due to inadequate design
    and testing is one scenario that could explain the fall of Mr. Pike.” Newquist opined:
    “Sunset/ABSS failed to act as a responsible manufacture of a ladder
    with the requisite testing records to verify that its ladders had the
    required design and strength to prevent collapse.
    Based on the standards of care for complying with ANSI standards,
    Sunset/ABSS should have the ladder documents documented for
    years. Sunset/ABSS was in deviation of these ANSI and OSHA
    Standards and this was a substantial factor in Mr. Pike’s injuries on
    June 7, 2015.
    In summary, Sunset/ABSS failed to provide a workplace free of
    hazards and failed to comply with recognized industry and OSHA
    -10-
    1-21-0676
    standards for ladders. These deficiencies were a cause of Mr. Pike’s
    accident and injuries.”
    ¶ 28     Newquist’s Deposition Testimony
    ¶ 29   At his deposition, Newquist testified that he is a “ladder safety expert” but not an expert in ladder
    design. Newquist did not have an opinion as to whether the fiberglass component of the subject
    ladder was defective. He also acknowledged that he had not identified a “design defect” in the
    ladder that related to the accident.
    ¶ 30   Asked if there was a “hazard in the ladder itself,” Newquist answered that “one scenario is that
    there was a defect that was missed and another scenario is the ladder had no ability to support Mr.
    Pike’s weight.” That is, he differentiated between a “defect Mr. Brown missed” as opposed to “an
    internal problem, that you would not have caught.” Newquist agreed that there was no evidence
    suggesting that the ladder had a visible defect, such as a crack, that Brown “missed” before Pike
    attempted to climb the ladder.
    ¶ 31   Newquist agreed it was possible that undetectable damage to the ladder could have “impair[ed]
    the load bearing integrity of the ladder” and contributed to the accident. He agreed that since the
    ladder had been used for two years before the accident, it was “not in the same condition” as when
    it was originally sold, due to “wear and tear.”
    ¶ 32   Newquist testified to his belief that Pike was not qualified to use the subject ladder, based on
    Pike’s deposition testimony that he had not been trained in ladder safety. Newquist agreed that a
    ladder should not be used in excess of its duty rating, and that it is an unsafe practice to climb the
    ladder in excess of its duty rating. Newquist agreed that it would be an “overload” for a 350-pound
    person to use the subject ladder, and that one should not overload the ladder “[b]ecause that’s what
    the manufacturer made it to handle.” He testified that overloading the ladder can “possibly create
    -11-
    1-21-0676
    a collapse if the ladder is old” and that “as [ladders] get older, they get weaker.” Newquist agreed
    with the statement that “Pike should not have used this ladder if he weighed 350-plus pounds
    because the ladder was rated only for 300 pounds.”
    ¶ 33   Nonetheless, Newquist elsewhere testified that the ladder should have supported “3.3 or 4 times
    the rated load” and that “the OSHA standard means a ladder has to be supporting four times the
    maximum intended load.” Asked if the ladder would collapse if Pike weighed 301 pounds (one
    pound more than its stated capacity), Newquist answered: “If the ladder was properly designed,
    there are safety factors. One pound would not make a difference.” However, Newquist was
    equivocal as to whether the ladder should have supported 350 pounds:
    “Q. Do you know if the safety factors should have prevented the ladder
    from collapsing even at 350 pounds while just ascending it?
    A. If everything was done correctly with the manufacturer, it should not
    have collapsed.
    Q. Even at 350, correct?
    A. We don’t know because there’s no testing at 350 by these companies.
    Q. Okay. So you don’t know one way or the other if it would have
    collapsed at 350 if the ladder was perfect, correct?
    A. That’s correct.”
    ¶ 34    Motion for Summary Judgment
    ¶ 35   On February 1, 2021, ABSS and Sunset jointly filed a motion for summary judgment, arguing
    there was no evidence that a defect in the ladder existed when it left their control. 4 They argued
    that Pike needed expert testimony to establish a specific defect, but his expert, Newquist, had
    4
    ABSS and Sunset are represented by the same counsel.
    -12-
    1-21-0676
    “identified neither a design defect nor a manufacturing defect” and offered no opinion about the
    ladder’s warnings.
    ¶ 36   Elsewhere in the motion, ABSS and Sunset acknowledged that even without expert testimony
    identifying a specific defect, a plaintiff may prevail in strict liability if he proves (1) there was no
    abnormal use of the product, (2) that there was no reasonable secondary cause of the injury, and
    (3) that the product failed to perform in the manner reasonably expected in light of its intended
    function. However, they urged that Pike could not “rule out abnormal use or reasonable secondary
    causes of plaintiff’s fall.” They pointed out that the ladder was over two years old at the time of
    the incident, and that Newquist acknowledged that the ladder might have had undetected damage.
    ¶ 37   They also noted that Pike “weighed more than the ladder’s duty rating” and there was no evidence
    to “rule out how plaintiff’s weight might have caused or contributed to the accident.” ABSS and
    Sunset urged that Pike could not succeed on a “non-specific defect theory” because there was
    “evidence of abnormal use (plaintiff weighing more than the duty rating) and reasonable secondary
    causes (prior undetected damage, plaintiff losing his balance).” Thus, ABSS and Sunset argued
    that summary judgment in their favor was warranted.
    ¶ 38   In response to the motion, Pike argued that summary judgment was improper because a “jury
    should decide whether or not a 2-year old ladder designed and manufactured to hold over 900 lbs.
    was unreasonably dangerous” when it “collapsed under the Plaintiff, who only weighed 350
    [pounds].” Pike argued that, despite the 300-pound load capacity, Becnel “admitted that the ladder
    needs to be designed and manufactured to hold over 900lbs” under ANSI standards. Pike recited
    Becnel’s testimony agreeing that ABSS ladders are designed to support 900 to 1200 pounds and
    should not fail even under a 375-pound or 500-pound person. Pike claimed ABSS did not show
    -13-
    1-21-0676
    that it “complied with ANSI standards”, pointing out that the only testing documents produced
    were from 2004 (before the ladder’s manufacture) and 2017, two years after Pike’s injury.
    ¶ 39   Pike did not dispute that Newquist had not identified a specific defect. However, Pike cited
    authority that expert opinions and proof of a specific defect is not necessary in a strict liability
    case, if circumstantial evidence demonstrates the product did not perform in manner reasonably to
    be expected by the consumer. Pike cited case law for the proposition that there is prima facie case
    of strict liability where a ladder collapses without any sign of prior damage, where there is no
    evidence of abnormal use or reasonable secondary causes. Pike argued there was undisputed
    testimony that the ladder had no prior signs of damage, that it was on a stable surface with its
    cross-braces locked, and that Pike ascended the ladder properly.
    ¶ 40   Pike also challenged the suggestion that, because he weighed more than the 300-pound load
    capacity, his use of the ladder was abnormal or that he “misused” it. Pike argued that “misuse”
    occurs when a product is used for a purpose “neither intended nor reasonably foreseeable” by a
    defendant, but that his use of the ladder was an “intended and reasonably foreseeable use.” Pike
    also argued that there was no evidence to support any “speculative secondary causes” for the
    incident besides a product defect. Pike argued that he “need not exclude every possible cause” but
    was only required to show a “greater likelihood that his injury was caused by the defendant’s
    negligence than by some other cause.”
    ¶ 41   In their reply, ABSS and Sunset disputed that the record evidence permitted an inference of a
    defect. They urged that such an inference was inappropriate because “(1) the subject ladder was
    not new (2) it was regularly used on [a] commercial jobsite; (3) there is evidence of abnormal use
    (Plaintiff’s weight exceeded the ladder’s duty rating); and (4) Plaintiff’s own expert cannot rule
    out secondary causes of the accident.” ABSS and Sunset pointed out that the ladder was two years
    -14-
    1-21-0676
    old at the time of the accident. They also noted that their retained expert, Erick Knox, observed
    scrapes, gouges, abrasions and marks that were consistent with “normal use over roughly 2.5
    years.”
    ¶ 42   ABSS and Sunset argued that there was “abnormal use” precluding an inference of defect, because
    Pike “weighed in excess of the ladder’s duty rating.” ABSS and Sunset also asserted that Pike had
    not ruled out “reasonable secondary causes.” They noted that Newquist admitted the possibility
    that the ladder contained undetectable damage before Pike used it. ABSS and Sunet averred that
    Pike could not rule out “the reasonable explanation that Charlie Brown was able to climb up the
    subject ladder with undetectable damage, but Plaintiff, who weighed 125 pounds more, was not.”
    ABSS and Sunset urged this “prevent[ed] an inference of a defect,” such that Pike could not
    establish a prima facie case of strict liability.
    ¶ 43   As an exhibit to their reply brief, ABSS and Sunset attached an affidavit from Knox, in which he
    stated that his inspection of the ladder showed “miscellaneous non-structural scrapes, gouges, and
    transfer on the ladder at various locations.” Knox opined that the “majority of these conditions
    were present prior to the June 7, 2015 accident” but “did not affect the structural integrity or
    stability of the ladder.” Knox stated that the ladder “exhibited signs of wear consistent with a
    ladder that was regularly used over approximately 2.5 years in a commercial capacity.”
    ¶ 44     Summary Judgment Ruling
    ¶ 45   The record reflects that the court conducted a hearing on ABSS and Sunset’s summary judgment
    motion on May 13, 2021. However, the record on appeal does not contain a transcript of that
    hearing. 5
    5
    This court’s records reflect that on June 25, 2021, Pike submitted to our court a request for preparation of
    the transcript from the May 13, 2021 hearing. However, no report of proceedings has been filed in this
    court. The record on appeal consists only of the common law record.
    -15-
    1-21-0676
    ¶ 46   On May 13, 2021, the trial court entered a single-page order granting summary judgment to ABSS
    and Sunset with respect to Pike’s claim for strict liability. That order did not state the trial court’s
    reasoning. The court specified that there was “no just cause to delay enforcement or appeal” of the
    order, permitting us to exercise appellate jurisdiction pursuant to Supreme Court Rule 304(a).6
    ¶ 47     Post-Appeal Orders
    ¶ 48   On June 11, 2021, Pike filed his notice of appeal from the order granting ABSS and Sunset’s
    motion for summary judgment. On September 30, 2021, this court dismissed the appeal for want
    of prosecution because Pike had not filed a record on appeal. Our supreme court subsequently
    entered a supervisory order directing us to vacate the September 30, 2021 order and allow Pike
    further time to file the record on appeal. Accordingly, on December 2, 2021, we reinstated the
    appeal. The record on appeal was filed in this court on January 6, 2022.
    ¶ 49                                                 ANALYSIS
    ¶ 50   On appeal, Pike argues that the court erred in granting summary judgment in favor of ABSS and
    Sunset, as he asserts there was evidence creating a genuine issue of material fact as to his claim
    for strict liability pursuant to Tweedy v. Wright Ford Sales, Inc., 
    64 Ill. 2d 570
    , 574 (1976).
    Importantly, Pike does not attempt to argue that he produced expert testimony describing any
    specific defect in the ladder at issue. Instead, he asserts that even without expert testimony about
    a specific defect, the circumstantial evidence is sufficient to support an inference of a defect in the
    ladder when it left the control of ABSS and Sunset. ABSS and Sunset respond that summary
    6
    Also on May 13, 2021, the court entered separate orders (1) denying Freeman and Freeman Electrical’s
    motion for summary judgment with respect to Pike’s claims against them and (2) denying Absolute’s
    motion to dismiss the counts asserted against it in Freeman’s third-party complaint. Those orders are not at
    issue in the instant appeal.
    -16-
    1-21-0676
    judgment was properly entered in their favor, where (1) there is no expert testimony regarding a
    specific defect and (2) the circumstantial evidence does not support an inference of defect under
    Tweedy and related precedent. In particular, they argue that the Tweedy approach applies only in
    the absence of abnormal use of the product, and if other reasonable causes can be ruled out. Given
    the fact that Pike weighed more than the load capacity and other evidence, ABSS and Sunset
    contend that Pike cannot meet these requirements to support an inference of defect and survive
    summary judgment.
    ¶ 51   For the following reasons, we agree with ABSS and Sunset and affirm the trial court’s entry of
    summary judgment.
    ¶ 52    Standard of Review
    ¶ 53   “Summary judgment is appropriate only where ‘the pleadings, depositions, and admissions on file,
    together with the affidavits, if any, show that there is no genuine issue as to any material fact and
    that the moving party is entitled to a judgment as a matter of law.’ ” Carney v. Union Pacific R.R.
    Co., 
    2016 IL 118984
    , ¶ 25 (quoting 735 ILCS 5/2-1005(c) (West 2012)). “In determining whether
    a genuine issue as to any material fact exists, a court must construe the pleadings, depositions,
    admissions, and affidavits strictly against the movant and liberally in favor of the opponent.” Lewis
    v. Lead Industries Ass’n, 
    2020 IL 124107
    , ¶ 15. “Because summary judgment is a drastic means
    of disposing of litigation, a court must exercise extraordinary diligence in reviewing the record so
    as not to preempt a party’s right to fully present the factual basis for its claim.” Northern Illinois
    Emergency Physicians v. Landau, Omahana & Kopka, Ltd., 
    216 Ill. 2d 294
    , 306 (2005).
    ¶ 54   Although a plaintiff is not required to prove his case, summary judgment is appropriate if a plaintiff
    cannot establish an element of his claim. Id.; see also Lewis v. Lead Industries Ass’n, 2020 IL
    -17-
    1-21-0676
    124107, ¶ 15. (“If the plaintiff fails to establish any element of the cause of action, summary
    judgment for the defendant is appropriate. [Citations.]”).
    ¶ 55   “A defendant moving for summary judgment may meet its initial burden of proof by affirmatively
    showing that some element of the case must be resolved in his favor or by establishing that there
    is an absence of evidence to support the nonmoving party’s case. [Citation.]” Freedberg v. Ohio
    Nat. Ins. Co., 
    2012 IL App (1st) 110938

    ¶ 57    Elements of a Strict Liability Claim
    ¶ 58   Here, Pike’s sole theory of liability against both ABSS and Sunset is strict liability for a defective
    product. We review the elements of that claim.
    ¶ 59   “Under common law, all entities in the distributive chain of an allegedly defective product *** are
    strictly liable in product liability action for injuries result from that product.” Murphy v. Mancari’s
    Chrysler Plymouth, Inc., 
    381 Ill. App. 3d 768
    , 773 (2008). “This liability is predicated on a finding
    that the product is unreasonably dangerous, regardless of fault. [Citation.]” 
    Id.
     A strict liability
    claim “ ‘focuses on the product rather than the conduct of the manufacturer.’ ” Blue v.
    Environmental Engineering, Inc., 
    215 Ill. 2d 78
    , 94 (2005) (quoting Restatement (Third) of Torts:
    Products Liability § 1, Comment a, at 7 (1998)).”
    ¶ 60   “To recover in a product liability action, a plaintiff must plead and prove that the injury resulted
    from a condition of the product, that the condition was an unreasonably dangerous one, and that
    the condition existed at the time the product left the manufacturer’s control. [Citations.]” Sollami
    v. Eaton, 
    201 Ill. 2d 1
    , 7 (2002). “A product may be found unreasonably dangerous by virtue of a
    -18-
    1-21-0676
    physical flaw, a design defect, or a failure of the manufacturer to warn of the danger or instruct on
    the proper use of the product as to which the average consumer would not be aware. [Citation.]”
    
    Id.
    ¶ 61   A manufacturing defect claim is distinct from claim of defective design or inadequate warning. “A
    manufacturing defect differs from a design defect in that the former occurs in only a small
    percentage of units in a product line, where the latter arises when the specific unit conforms to the
    intended design but the intended design itself or its sale without adequate instructions or warnings
    renders the product not reasonably safe.” Blue, 
    215 Ill. 2d 78
    , 89-90 (citing Restatement (Third)
    of Torts: Product Liability § 1, Comment a, at 6 (1998.)) “A manufacturer is liable for
    [manufacturing] defects no matter how adequate and careful its quality control may have been.
    However, a design defect suit is more akin to a negligence claim.” Id. at 95.
    ¶ 62   Claims of manufacturing defect are subject to the “consumer-expectation test” derived from
    section 402A of the Restatement (Second) of Torts. Blue, 
    215 Ill. 2d at 90
    . Under that inquiry, “A
    product is unreasonably dangerous when it is dangerous to an extent beyond that which would be
    contemplated by the ordinary consumer who purchases it, with the ordinary knowledge common
    to the community as to its characteristics.” (Internal quotation marks omitted.) 
    Id. at 91
    .
    ¶ 63   Notably, although Pike’s complaint alleged that the ladder was defective in “one or more” respects,
    including failure to “meet industry design standards” or “fail[ure] to contain adequate warnings
    regarding weight limitations,” his briefing in the trial court and in this court relies solely on a
    manufacturing defect theory. Pike does not suggest that there was any evidence of a flaw in the
    ladder’s design—to the contrary, he suggests that the ladder was designed to be able to support at
    least 900 pounds. Nor does he suggest there was any deficiency in the ladder’s labeling or
    -19-
    1-21-0676
    warnings. 7 Rather, he claims that there is evidence raising a factual issue as to whether there was
    a flaw in the ladder’s manufacture when it left ABSS’s control that caused his injury.
    ¶ 64    Requisite Proof to Support an Inference of Defect
    ¶ 65   Pike does not dispute that his expert, Newquist, did not specify a particular defect that caused the
    ladder to collapse. However, he argues that he met the quantum of proof necessary to sustain a
    strict liability action pursuant to our supreme court’s decision in Tweedy v. Wright Ford Sales,
    Inc., 
    64 Ill. 2d 570
    , 574 (1976), and related precedent.
    ¶ 66   Tweedy established that circumstantial evidence sometime may support an inference of defect
    supporting strict liability. In, Tweedy defendant Ford Motor Company appealed following a jury
    verdict in plaintiff’s favor. At trial, the evidence showed that the brakes on a Ford vehicle failed
    when it had been driven approximately 7,500 miles, following an inspection at 6000 miles.
    Plaintiff did not offer any expert testimony regarding any specific defect in the automobile brake
    system. Id at. 572. Before our supreme court, Ford argued that plaintiff failed to prove that the
    vehicle was defective when it left Ford’s control, and that “evidence of the malfunction when
    plaintiff was injured did not prove a defect.” 
    Id. at 573
    .
    ¶ 67   Our supreme court disagreed, holding that “[a] prima facie case that a product was defective and
    that the defect existed when it left the manufacturer’s control is made by proof that in the absence
    of abnormal use or reasonable secondary causes the product failed to perform in the manner
    reasonably to be expected in light of [its] nature and intended function.” (Internal quotation marks
    7
    Given his admission that he never read the warnings, Pike could not successfully claim that his injury was
    proximately caused by an inadequate warning. See Kane v. R.D. Werner Co., 
    275 Ill. App. 3d 1035
     (1995)
    (plaintiff who did not read allegedly inadequate warning cannot maintain a product liability action based
    on negligent failure to warn, unless nature of inadequacy is that it prevented him from reading the
    warnings).
    -20-
    1-21-0676
    omitted.) 
    Id. at 574
    . The Tweedy court noted that the evidence showed that the automobile had
    been inspected and “subjected to no abnormal use” before the incident, but it “failed to function in
    the manner reasonably to be expected.” 
    Id.
     Further, the “[p]laintiff was driving carefully at a
    reasonable rate of speed *** and there was no evidence of any reasonable secondary cause.” 
    Id. at 574-75
    .
    ¶ 68   Following Tweedy, “courts in this State have generally held that a plaintiff need not pinpoint the
    specific defect in a product in order to recover under strict liability.” Doyle v. White Metal Rolling
    & Stamping Corp., 
    249 Ill. App. 3d 370
    , 377 (1993). “Instead, a plaintiff may create an inference
    that a product was defective by direct or circumstantial evidence that (1) there was no abnormal
    use of the product; (2) there was no reasonable secondary cause of the injury; and (3) that the
    product failed to perform in the manner reasonably to be expected in light of its nature and intended
    function. [Citations.]” 
    Id.
    ¶ 69   Doyle, which also concerned a ladder, illustrates the distinction between a claim alleging a specific
    defect and a claim relying on an inference of defect. The Doyle plaintiff brought a two-count
    product liability action, in which count I alleged the ladder was “ ‘unreasonably dangerous for
    users because [it] failed to perform in a manner reasonably expected since it was incapable of
    sustaining human weight when used in a foreseeable manner without collapsing.’ ” 
    Id. at 372
    . Our
    court in Doyle referred to this as the “Tweedy count.” 
    Id. at 377, 379
    . The second count alleged a
    specific defect, namely, that the ladder’s rear rails were too weak and its steps were too narrow.
    
    Id. at 372
    . On appeal from a jury verdict for plaintiff, our court held that the jury instructions
    regarding count I “misstated the law” where they “allowed the jury to find that the ladder was
    unreasonably dangerous if it found only that the ladder failed to perform in the manner reasonably
    to be expected in light of its intended function.” 
    Id. at 379
    . Our court in Doyle explained that since
    -21-
    1-21-0676
    “no specific defect in the product was alleged, plaintiff was required to prove that he did not use
    the product in an unreasonable manner and that no reasonable secondary causes of his injury
    existed.” 
    Id.
     Nevertheless, our court found that this error with respect to count I did not merit
    reversal, because the jury was not asked to specify whether it based its verdict on count I or count
    II. 
    Id. at 379-80
    .
    ¶ 70   In this appeal, Pike acknowledges that Newquist did not identify to a specific defect in the ladder
    that caused the collapse. Regardless, he contends that, pursuant to Tweedy, there was sufficient
    direct or circumstantial evidence to create an inference that the ladder was defective. He claims
    there is a prima facie case of strict liability because the ladder had “no sign of damage” and there
    is “no evidence of ‘abnormal use or reasonable secondary causes.’”
    ¶ 71   Pike suggests the circumstantial evidence was akin to that in other ladder cases where there was
    sufficient evidence to support strict liability. Pike relies largely on Gillespie v. R.D. Werner Co.,
    
    71 Ill. 2d 318
     (1978), where our supreme court affirmed a plaintiff’s jury verdict, over the
    manufacturer’s contention that it was entitled to judgment notwithstanding the verdict. Our
    supreme court found sufficient evidence to establish a prima facie case of strict liability, where
    “the evidence d[id] not show ‘abnormal use or reasonable secondary causes” for the ladder’s
    collapse. 
    Id. at 320-21
    . Our supreme court emphasized the testimony that the plaintiff, Gillespie,
    used the ladder properly:
    “Gillespie and his aide, finding the ladder to be ‘new’ and nothing
    wrong with it, used it while doing electrical work above a drop
    ceiling. The helper handed tools to Gillespie * * *. Gillespie denied
    he worked to the side in such a way as to cause an imbalance. The
    concrete floor was level and covered with tiles. The owner and
    -22-
    1-21-0676
    operator of the company renting the ladder to Gillespie’s employer
    testified that it was his practice ‘to check and insect all equipment’
    he rented out. Given this evidence, it was reasonable for the jury to
    conclude there was an absence of abnormal use and that the ladder
    failed ‘to perform in the manner reasonably to be expected in light
    of’ its ‘intended function.’ ” 
    Id. at 321-22
    .
    ¶ 72   Our supreme court in Gillespie expressly distinguished a Massachusetts supreme court decision
    that entered judgment for a ladder manufacturer, where there was “no evidence that the plaintiff
    put the ladder to the normal use for which it was intended.’” 
    Id.
     at 322 (citing Coyne v. John S.
    Tilley Co., 
    368 Mass. 230
    , 
    331 N.E. 2d 541
     (1975)). In contrast to that case, our supreme court in
    Gillespie found “there was sufficient evidence for the jury to infer that Gillespie could be
    eliminated as a cause of his injuries,” reiterating the testimony that he properly used the ladder. 
    Id. at 322-23
    . That is, “ ‘a trier of fact could infer as [a] matter of common knowledge that a relatively
    new *** properly fabricated and designed aluminum ladder which had received proper care and
    usage would not collapse if put to the use for which it was intended.’” 
    Id. at 323
     (quoting Coyne,
    
    331 N.E. 2d at 545
    ).
    ¶ 73   Pike also directs our attention to Tulgetske v. R.D. Werner, 
    86 Ill. App. 3d 1033
     (1980), which
    rejected a ladder manufacturer’s contention that it was entitled to a directed verdict, due to lack of
    evidence of defect. In Tulgetske, this court reiterated that a prima facie case can be made by proof
    that in the absence of abnormal use or reasonable secondary causes, the product failed to perform
    in the manner reasonably to be expected. 
    Id. at 1038
    . We concluded that there was proof from
    which the jury could find a defect, even without expert testimony, where “there was evidence that
    the plaintiff inspected the ladder, and it appeared to be in good condition; that he placed the ladder
    -23-
    1-21-0676
    firmly on solid ground in a stable position; that his use of the ladder was normal and foreseeable;
    that he felt the ladder give way and ‘crunch’ beneath him.” 
    Id.
     In light of plaintiff’s testimony and
    corroborating witnesses, we found it was “reasonable for the jury to conclude that there was no
    abnormal use and that the ladder failed to perform in the manner reasonably to be expected in the
    light of its intended function.” 
    Id.
    ¶ 74   Pike suggests that the evidence here is similar to that in Gillespie and Tulgetske. He claims that
    the ladder in this case was “relatively new” and in “good condition” with “no defects noted upon
    inspection.” He suggests the evidence shows the ladder “was being used in a normal and
    foreseeable way” before the incident, such that a defect can be inferred. In urging that there is no
    evidence of “abnormal use,” he cites his undisputed testimony that the ladder was on a flat surface,
    its cross braces were locked, and that he climbed it “with his body centered between the two rails
    of the ladder with his right hand on the right rail and his left hand on the left rail.”
    ¶ 75   In response, ABSS and Sunset contend that Pike cannot establish a prima facie case of strict
    liability based on an inference of defect for two reasons. First, they claim that Pike failed to show
    the absence of “abnormal use.” Second, they assert that Pike failed to offer evidence to eliminate
    “reasonable secondary causes” of the incident. We address those in turn.
    ¶ 76    Evidence of Pike’s “Abnormal Use”
    ¶ 77   First, we agree that Pike cannot show the absence of “abnormal use,” as that term is used in Tweedy
    and its progeny, as it is undisputed that Pike weighed approximately 350 pounds, exceeding the
    ladder’s stated load capacity of 300 pounds. We note that there is no dispute that the ladder’s load
    capacity was clearly labeled. Pike has never contended that the labeling was inadequate or that he
    could not see it. Instead, he acknowledged that he did not check the label, indicating he assumed
    the ladder would support him. There is no question that Pike overloaded the ladder. Tellingly,
    -24-
    1-21-0676
    Pike’s own expert acknowledged that ladders should not be loaded beyond their capacity rating.
    We believe this establishes an absence of abnormal use.
    ¶ 78   Pike disputes the proposition that his use of the ladder beyond its stated 300-pound capacity
    equates to abnormal use or “misuse.” He directs our attention to Arellano v. SGL Abrasives, 
    246 Ill. App. 3d 1002
     (1993). However, we find that decision is inapplicable.
    ¶ 79   In Arellano, plaintiff suffered injuries while working in a foundry, when the grinding wheel he
    was using broke and exploded after 10 or 15 minutes of use. The defendant manufacturer denied
    any defect and claimed plaintiff misused the wheel. 
    Id. at 1003
    . At trial, defendant offered expert
    testimony that plaintiff could have avoided injury by using a guard on the grinding wheel. 
    Id. at 1005
    .The defense expert opined that the wheel at issue broke due to either product misuse, or
    damage after its manufacture. 
    Id.
    ¶ 80   The jury returned a general verdict for plaintiff but found that due to plaintiff’s product misuse,
    damages should be reduced by 70%. 
    Id. at 1003
    . After post-trial motions, the trial court granted
    defendant judgment notwithstanding the verdict (j.n.o.v.) and vacated the jury’s misuse finding.
    
    Id.
     Plaintiff appealed the grant of j.n.ov., and defendant cross-appealed the vacation of the misuse
    finding. 
    Id.
    ¶ 81   Our court first found that j.n.o.v for defendant was improper, as there was sufficient evidence from
    which the jury could infer a manufacturing defect in the broken wheel. 
    Id. at 1006-07
     (noting the
    jury could credit plaintiff’s testimony that he “assured that [the wheel] was properly mounted”
    before use.) That is, the jury could credit his testimony that he was injured by “a new grinding
    wheel after normally mounting it and using it normally for a short period of time.” 
    Id. at 1009
    .
    -25-
    1-21-0676
    ¶ 82   This court then addressed the cross-appeal, in which defendant sought reinstatement of the jury’s
    finding of misuse because “plaintiff’s use of the grinding wheel without a guard constituted
    misuse.” 
    Id.
     Arellano explained the concept of misuse as follows:
    “[P]roduct misuse is an affirmative defense which operates to
    reduce a plaintiff’s recovery by the amount of fault apportioned to
    him. Misuse of a product occurs when it is used for a purpose neither
    intended nor reasonably foreseeable by the defendant based on an
    objective standard. The manner in which the particular purpose was
    being accomplished is not an issue under a theory of misuse.
    [Citation.]” 
    Id. at 1010
    .
    ¶ 83   Arellano proceeded to reject defendant’s misuse argument, explaining:
    “Plaintiff was clearly doing an act of grinding when injured.
    Grinding is an intended and reasonably foreseeable use of a grinding
    wheel. The absence of the guard goes to the manner in which the
    grinding wheel was being used. If anything, plaintiff was
    contributory negligent in using the grinder without a guard.
    Contributory negligence, however, is not a defense to strict liability.
    [Citation.]” 
    Id.
    ¶ 84   Here, Pike argues that, just as grinding the wheel in Arellano was an intended and reasonably
    foreseeable use, in this case he did not “misuse” the ladder because “climbing the ladder was also
    the obvious intended and reasonably foreseeable use of the ladder.” He also avers that, because
    “redundancy is required to be built into every ladder per ANSI and OSHA standards, clearly there
    is an expectancy that a ladder must be able to be used over its intended load capacity.” Thus, he
    -26-
    1-21-0676
    claims there was an absence of “abnormal use,” which permits an inference of defect pursuant to
    Tweedy.
    ¶ 85   We find Pike’s reliance on Arellano is unavailing for multiple reasons. First, the case law does not
    indicate that the defense of “misuse” discussed in Arellano is equivalent to the concept of
    “abnormal use”, in the context of an inference of defect where a product malfunctions “in the
    absence of abnormal use or reasonable secondary causes.” Gillespie, 
    71 Ill. 2d at 321
     (quoting
    Tweedy, 
    64 Ill. 2d at 574
    ). “[M]isuse is an affirmative defense” to reduce a plaintiff’s recovery.
    Arellano, 246 Ill. App. 3d at 1010; see also Williams v. Brown Mfg. Co, 
    45 Ill. 2d 418
    , 425-26
    (1970) (“[I]t has generally been recognized in Illinois and elsewhere that plaintiffs who ‘misuse’
    a product—uses it for a purpose neither intended nor ‘foreseeable’ (objectively reasonable) by the
    defendant—may be barred from recovery. [Citations.]” In contrast, evidence showing a lack of
    “abnormal use” is a prerequisite to support an inference of defect in a strict liability case. Tweedy,
    
    64 Ill. 2d at 574
    ; Doyle, 249 Ill. App. 3d at 377.
    ¶ 86   Moreover, even if we were to conclude that the definition of “misuse” applies equally to the
    concept of “abnormal use”, it would still be unavailing to Pike under the facts of this case. Misuse
    occurs when a product “is used for a purpose neither intended nor reasonably foreseeable by the
    defendant based on an objective standard.” (Emphasis added.) Arellano, 246 Ill. App. 3d at 1010.
    ¶ 87   In our view, the evidence is clear and undisputed that the manufacturer did not “intend” for the
    ladder at issue to be climbed by someone weighing over 300 pounds. To the contrary, the evidence
    makes clear that such use was unintended and abnormal. There is no dispute that the ladder’s duty
    rating was 300 pounds, which was explicitly stated on the label. Although Becnel acknowledged
    that ABSS ladders were designed to be capable of supporting a much heavier person, he testified
    that the stated capacity is “the capacity that you’re not supposed to exceed.” Significantly,
    -27-
    1-21-0676
    plaintiff’s own expert, Newquist, agreed that it would be an “overload” for a 350-pound person to
    use the ladder, and that one should not overload the ladder “[b]ecause that’s what the manufacturer
    made it to handle.” Newquist agreed with the statement that “Pike should not have used this ladder
    if he weighed 350-plus pounds because the ladder was rated only for 300 pounds.”
    ¶ 88   Indeed, Pike’s opening brief essentially acknowledges that persons weighing more than 300
    pounds were not “intended” users, insofar as he claims there is an “expectation that a ladder must
    be able to be used over its intended load capacity.” (Emphasis added). On this point, we recognize
    there was evidence that ABSS ladders were designed to be capable of holding more weight than
    the stated load capacity, consistent with ANSI and OSHA standards. Despite evidence that ABSS
    ladders were designed with this redundancy, that does not mean ABSS intended for persons
    weighing more than 300 pounds to climb on ladders with a duty rating indicating a 300-pound
    capacity. While evidence of this redundancy could be relevant to whether use by a heavier person
    was foreseeable to the manufacturer, that is a distinct matter from whether such use was intended.
    See Arellano, 246 Ill. App. 3d at 1010 (misuse use occurs where a product “is used for a purpose
    “neither intended nor reasonably foreseeable by the defendant”).
    ¶ 89   For the same reasons, we agree with ABSS and Sunset that Pike cannot establish a lack of
    “abnormal use of the product,” which is necessary to support an inference of defect. Doyle, 249
    Ill. App. 3d at 377. Rather, we think it is apparent that where a 350-pound person climbs on a
    ladder that has a rated capacity of 300 pounds, this constitutes “abnormal use” of the product. This
    plainly distinguishes this case from the other ladder cases cited by Pike, where there was evidence
    that the ladders were properly used and not overloaded. See Gillespie, 
    71 Ill. 2d at 323
     (based on
    testimony describing plaintiff’s use of ladder, “an inference could be made that the ladder was not
    overloaded”); Tulgetske, 86 Ill. App. 3d at 1038, (plaintiff made a prima facie case where there
    -28-
    1-21-0676
    was evidence that plaintiff’s “use of the ladder was normal and foreseeable”). In contrast, here
    there is uncontroverted evidence that Pike overloaded the ladder by approximately 50 pounds.
    Pike’s abnormal use precludes him from creating an inference of defect, such that ABSS and
    Sunset were entitled to summary judgment.
    ¶ 90   To be clear, our conclusion does not indicate that an injured person whose weight exceeded the
    intended capacity can never establish liability for a defect. However, in this appeal, Pike does not
    identify any evidence of a specific manufacturing defect, or any design defect or inadequate
    warning.8 The sole theory of strict liability pursued by Pike requires proof to support an inference
    of defect, including evidence that there was not “abnormal” use. See Doyle, 249 Ill. App. 3d at 377
    (a plaintiff may create an inference of defect through evidence that “there was no abnormal use of
    the product”, there was “no reasonable secondary cause of the injury” and the product failed to
    perform in the manner reasonably to be expected). Our conclusion that Pike cannot establish the
    absence of “abnormal use” is independently dispositive in favor of ABSS and Sunset.
    ¶ 91      The Evidence Does Not Rule Out Reasonable Secondary Causes
    ¶ 92   Although we could affirm solely due to Pike’s abnormal use, we also note that summary judgment
    is otherwise warranted because Pike cannot show that there was “no reasonable secondary cause
    of the injury,” which is otherwise required to create an inference of a manufacturing defect
    pursuant to Tweedy and its progeny. Id.; see also Gillespie, 
    71 Ill. 2d at 321
     (a prima facie case of
    defect “is made by proof that in the absence of abnormal use or reasonable secondary causes” the
    product failed to perform in the manner reasonably to be expected).
    8
    To the extent Pike references the lack of testing documents produced by ABSS and Newquist’s corresponding
    opinion that testing was inadequate, that does not suggest any specific defect in the manufacture of the ladder at
    issue. Moreover, insofar as Pike is only pursuing a strict liability manufacturing defect claim (not a negligence
    claim), evidence of a defendant’s conduct is irrelevant. See Blue, 
    215 Ill. 2d at 95
    .

    ¶ 93   Based on the undisputed evidence, we agree with ABSS and Sunset that reasonable secondary
    causes cannot be ruled out. First, as discussed, there is undisputed evidence that Pike overloaded
    the ladder approximately 50 pounds beyond its 300-pound duty rating. Regardless of whether this
    is considered “abnormal use,” the admitted overloading of the ladder otherwise constitutes a
    reasonable secondary cause of the collapse that cannot be ruled out. This is especially the case,
    since it was undisputed that the ladder was over two years old at the time of Pike’s injury in June
    2015, having been manufactured by ABSS in 2013. The record indicates that after it was delivered
    to Freeman in 2013, the ladder could have been used numerous times at various job sites before
    the date of Pike’s injury. Pike’s expert acknowledged that “as [ladders] get older, they get weaker”
    and that the subject ladder would not be in its original condition due to “wear and tear.” Elsewhere,
    he testified that overloading the ladder can “possibly create a collapse if the ladder is old.” It is
    certainly a reasonable possibility that during its two-year period of use following manufacture, the
    ladder sustained damage and was weakened such that it could not support a 350-pound person.
    Indeed, Pike’s expert witness acknowledged that undetected damage to the ladder could have
    “impair[ed] the load bearing integrity of the ladder” and contributed to the accident.
    ¶ 94   Given this evidence, Pike cannot show “that there was no reasonable secondary cause of the
    injury”, an independent requirement to support an inference of defect. Doyle, 249 Ill. App. 3d at
    377. This independently warranted summary judgment in favor of ABSS and Sunset on Pike’s
    strict liability claim.
    ¶ 95                                            CONCLUSION
    ¶ 96   In summary, the undisputed evidence is such that Pike cannot show the absence of abnormal use
    of the ladder immediately before his injury. Moreover, the evidence shows that he cannot rule out
    reasonable secondary causes of his injury. In turn, the evidence does not support an inference of a
    -30-
    1-21-0676
    product defect necessary to support Pike’s strict liability claim against ABSS and Sunset.
    Accordingly, the summary judgment motion was properly granted in favor of ABSS and Sunset.
    ¶ 97   For the foregoing reasons, we affirm the judgment of the circuit court of Cook County.
