    IN THE COURT OF APPEALS OF THE STATE OF KANSAS
    ANITA CHRISTIANSEN,
    Appellant,
    v.
    HOWARD SILVERBRAND, Individually and as Trustee of the HOWARD SILVERBRAND
    LIVING TRUST, and LISA FAITH SILVERBRAND, Individually and as Trustee of the
    HOWARD SILVERBRAND LIVING TRUST,
    Appellees.
    SYLLABUS BY THE COURT
    1.
    We review a district court's decision to strike what it deems to be a contradictory
    affidavit for an abuse of discretion.
    2.
    A party may not avoid summary judgment by presenting an affidavit that
    contradicts prior sworn deposition testimony. This has been called the "sham affidavit
    doctrine."
    3.
    Finding an affidavit is a sham and striking its consideration requires a two-part
    inquiry. First, the court determines whether a contradiction exists. Second, the court
    determines whether the contradiction is justified. The court must consider the contents
    and the context of the prior testimony.
    1
    4.
    When a movant demonstrates the lack of facts to support an essential element of
    the nonmovant's claim, the nonmovant has the affirmative duty to come forward with
    facts to support its claim, although it is not required to prove its case.
    5.
    Not every discrepancy in an affidavit justifies a district court's refusal to give
    credence to such evidence.
    6.
    An affidavit submitted along with a response to a motion for summary judgment
    does not contradict prior testimony when offered to provide clarification or expand on a
    previous sworn statement.

    Before ARNOLD-BURGER, C.J., ATCHESON and HURST, JJ.
    ARNOLD-BURGER, C.J.: The defendants in this case, Howard Silverbrand,
    individually and as trustee of the Howard Silverbrand Living Trust, and Lisa Faith
    Silverbrand, individually and as trustee of the Howard Silverbrand Living Trust
    (Silverbrand), moved for summary judgment in a slip and fall case brought by Anita
    Christiansen. Christiansen asserted that her injury was due to Silverbrand's poorly
    maintained parking lot. Silverbrand moved for summary judgment, asserting that
    Christiansen only admitted to slipping on ice in the parking lot, which was purportedly
    2
    not its responsibility. Along with her response in opposition to the motion, Christiansen
    submitted an affidavit stating that she slipped on the ice before breaking her ankle on a
    crack/pothole in the parking lot. The district court struck the affidavit, holding that it
    contradicted Christiansen's prior statements attributing her injury to slipping on the ice.
    The court granted the motion for summary judgment. Because we find that Christiansen's
    affidavit was supplementary, not contradictory, we reverse the district court's decision
    granting summary judgment to Silverbrand.
    FACTUAL AND PROCEDURAL HISTORY
    In the winter of 2016, Christiansen was working as a mail carrier for the United
    States Postal Service (USPS) in Great Bend. The parking lot where her work vehicle
    needed to be parked was owned by Silverbrand. Silverbrand was responsible for all
    maintenance of the parking lot. Clearing ice from the parking lot was the responsibility of
    USPS.
    As she exited her vehicle in the parking lot, Christiansen slipped and fell, breaking
    her ankle. She felt immediate and severe pain and yelled out for help, prompting a co-
    worker nearby to call an ambulance. Christiansen told the emergency medical technician
    (EMT) who arrived to treat her that she slipped on ice.
    Christiansen filed a personal injury lawsuit against Silverbrand, alleging that their
    negligence in maintaining the parking lot was the direct and proximate cause of her
    injuries. In the petition, she alleged that "[her] shoe got caught in a large pothole causing
    her to fall to the ground" and sustain injuries.
    Silverbrand ultimately moved for summary judgment. In the motion, Silverbrand
    generally asserted the uncontroverted facts showed that Christiansen slipped on ice in the
    parking lot. Because Silverbrand was not responsible for removal of ice from the parking
    3
    lot, Silverbrand argued that "[a]llowing this case to go forward to a jury trial will not
    change the facts as they currently exist. At this stage, summary judgment is warranted."
    Silverbrand attached several exhibits to their motion, which all contained statements by
    Christiansen that she either slipped or slid on the ice. In particular, she told the EMT and
    a treating physician she had slipped on black ice in the parking lot. In a response to
    Interrogatory No. 5 asking to "[p]lease describe in detail how the injury occurred," she
    stated, "As I stepped out of my [long-life vehicle (LLV)] after moving it forward, my
    right foot slid on ice and I fell down." Likewise, at a deposition, the following exchange
    occurred:
    "Q:    Okay. The slickness was where your vehicles was parked, is that correct?
    "A:    No.
    "Q:    Where was it?
    "A:    The slickness?
    "Q:    Yeah.
    "A:    The only place I experienced is when I stepped out of that LLV.
    "Q:    Okay. You don't deny what you've said, you slipped on the ice when you
    stepped out, do you?
    "A:    No.
    "Q:    You don't deny that you told the ambulance attendant EMT—let's see.
    His name is Reifsynder. No. Yes. Pardon Me. Yes, it is Reifsynder.
    You don't deny telling the EMT attendant when he asked you
    what happened that you slipped on the ice, isn't that–
    "A:    Do I deny it? No."
    Christiansen responded to Silverbrand's motion, asserting genuine factual disputes
    existed about whether the "parking lot created a dangerous condition, and whether
    [Silverbrand] acted reasonably in maintaining, inspecting and repairing their parking lot."
    She also generally argued that Silverbrand was not entitled to judgment as a matter of law
    because the lease agreement with the USPS required them to maintain and repair the
    parking lot, on top of a duty of reasonable care as the owners of the parking lot.
    4
    According to Christiansen, she slipped on ice as she exited her vehicle but "her foot
    caught the inside edge of a large crack/pothole in the parking lot," which caused her
    ankle to snap. As support, Christiansen attached to her response an affidavit stating, in
    relevant part:
    "8.       As I was stepping out of my vehicle, my right foot started sliding on ice.
    "9.       My right foot slid a couple of feet and then my foot caught the edge of a large
    crack/pothole in the parking lot. Sec photo of the location of my fall attached as
    Ex. A.
    "10.      When my shoe caught the edge of the large crack/pothole, I heard and felt a snap
    in my ankle and then saw a white impression under the skin where the bone had
    broken and was pressing against the skin as if it would pop out.
    "11.      I slid due to the ice.
    "12.      My ankle broke due to my foot hitting the crack/pothole in the parking lot."
    The district court held a pretrial hearing in February 2020 and heard argument
    from counsel at the outset on the motion for summary judgment. The district court took
    the matter under advisement and asked the parties to submit supplemental briefs on the
    issue of whether the court should consider Christiansen's "self-serving" affidavit as
    creating a controverted fact.
    Silverbrand's supplemental brief argued that Kansas Supreme Court held in Mays
    v. Ciba-Geigy Corp., 
    233 Kan. 38
    , Syl. ¶ 1, 
    661 P.2d 348
     (1983), that "[g]enerally a party
    may not defeat summary judgment by filing a subsequent affidavit impeaching his
    previous testimony upon deposition." Thus, Silverbrand asked the district court to sustain
    the motion for summary judgment because Christiansen had not submitted evidence to
    create an issue of fact.
    Christiansen argued in her supplemental brief that Mays did not support striking
    her affidavit because the facts of the cases were "vastly different." She asserted that her
    5
    affidavit was not inconsistent or contrary to her prior statements because she has never
    denied that she slipped and fell on ice, and the affidavit "clarifies" and supports her
    allegation that her ankle broke as a result of hitting the crack/pothole in the parking lot.
    Christiansen also argued the deposition was inadequate because it only lasted 25 minutes
    and counsel never asked her to fully explain the facts supporting her allegations.
    The district court ultimately granted Silverbrand's motion for summary judgment.
    The court noted Christiansen's affidavit was "the only evidence presented by the
    defendant to controvert the material fact in question" and that the affidavit "was at the
    very least [inconsistent] with prior statements that she gave to outside witnesses and to
    prior statements that she gave under oath." The court explained that Mays accurately
    stated the law but also mentioned more recent decisions citing Mays that addressed a
    similar issue. Deters v. Nemaha-Marshall Electric Cooperative Ass'n, 
    56 Kan. App. 2d 1170
    , 
    443 P.3d 1086
     (2019); Smith v. Kansas Orthopedic Center, 
    49 Kan. App. 2d 812
    ,
    
    316 P.3d 790
     (2013).
    The district court then explained that Christiansen had two "full" opportunities to
    describe the cause of the accident, yet both times she clearly stated she slipped on the ice
    and fell, injuring her ankle. The court also found that Christiansen's affidavit "tries to
    change that statement entirely by indicating that the ice was involved but it was the defect
    in the parking lot that caused her fall and injury." As a result, the court concluded the
    affidavit "is not a mere inconsistency but completely changes the liability of the
    defendant." In conclusion, the court decided to strike the affidavit and grant the motion
    for summary judgment.
    Christiansen timely appealed.

    ANALYSIS
    Christiansen argues on appeal the district court erred in granting summary
    judgment because genuine disputes of material fact existed to preclude judgment as a
    matter of law. Her argument on appeal and against summary judgment turns on the
    affidavit she submitted in response to Silverbrand's motion for summary judgment. In
    particular, the question is whether the district court erred in striking the affidavit because
    it only created a factual dispute by contradicting her prior sworn statements. According to
    Christiansen, the affidavit was not contradictory and merely clarified or supplemented her
    prior incomplete testimony.
    We review a district court's decision to strike an affidavit for an abuse of discretion.
    Although this appeal stems from the district court's grant of summary judgment,
    the issue is whether the district court erred in striking Christiansen's affidavit. We review
    a district court's decision to strike what it deems to be a contradictory affidavit for an
    abuse of discretion. P.W.P. v. L.S., 
    266 Kan. 417
    , 431, 
    969 P.2d 896
     (1998). A judicial
    action constitutes an abuse of discretion if (1) it is arbitrary, fanciful, or unreasonable;
    (2) it is based on an error of law; or (3) it is based on an error of fact. Biglow v.
    Eidenberg, 
    308 Kan. 873
    , 893, 
    424 P.3d 515
     (2018).
    A party cannot avoid summary judgment with an affidavit that contradicts prior sworn
    testimony.
    As mentioned, the district court refused to consider the affidavit under the Kansas
    Supreme Court's longstanding rule that a party may not avoid summary judgment by
    presenting an affidavit that contradicts prior sworn deposition testimony. Dawson v.
    Prager, 
    276 Kan. 373
    , Syl. ¶ 4, 
    76 P.3d 1036
     (2003) ("As a general rule, a party may not
    7
    defeat summary judgment by filing an affidavit that contradicts prior deposition
    testimony."); Mays, 
    233 Kan. 38
    , Syl. ¶ 1 (same).
    This is sometimes called the "sham affidavit doctrine." See Perma Research &
    Development Co. v. Singer Co., 
    410 F.2d 572
    , 578 (2d Cir. 1969) ("If a party who has
    been examined at length on deposition could raise an issue of fact simply by submitting
    an affidavit contradicting his own prior testimony, this would greatly diminish the utility
    of summary judgment as a procedure for screening out sham issues of fact."). "The
    concern in litigation . . . is that a party will first admit no knowledge of a fact but will
    later come up with a specific recollection that would override the earlier admission."
    Buckner v. Sam's Club, Inc., 
    75 F.3d 290
    , 292-93 (7th Cir. 1996) (refusing to allow the
    plaintiff's offsetting affidavit to preclude summary judgment, when the plaintiff had
    stated during her deposition that she "did not know" what object in the defendant's store
    had caused her fall, then asserted in an offsetting affidavit that the object was a ladies'
    watch, "one of the few objects that could directly link [the defendant] with the accident").
    Some argue that the sham affidavit doctrine conflicts with the court's role in
    summary judgment proceedings. In summary judgment, the moving party must show,
    based on the "pleadings, the discovery and disclosure materials on file, and any affidavits
    or declarations" that there are no genuine disputes of material fact and that they are
    entitled to judgment as a matter of law. K.S.A. 2020 Supp. 60-256(c)(2); Montgomery v.
    Saleh, 
    311 Kan. 649
    , 652, 
    466 P.3d 902
     (2020). "The district court must resolve all facts
    and reasonable inferences drawn from the evidence in favor of the party against whom
    the ruling [is] sought." (Emphasis added.) GFTLenexa, LLC v. City of Lenexa, 
    310 Kan. 976
    , 982, 
    453 P.3d 304
     (2019). When a movant establishes the lack of facts to support an
    essential element of the nonmovant's claim, the nonmovant "'has the affirmative duty to
    come forward with facts to support its claim, although it is not required to prove its
    case.'" Drouhard-Nordhus v. Rosenquist, 
    301 Kan. 618
    , 623, 
    345 P.3d 281
     (2015).

    "Summary judgment procedure is not a catch penny contrivance to take unwary litigants
    into its toils and deprive them of a trial, it is a liberal measure, liberally designed for
    arriving at the truth. Its purpose is not to cut litigants off from their right of trial by jury if
    they really have evidence which they will offer on a trial, it is to carefully test this out, in
    advance of trial by inquiring and determining whether such evidence exists." Whitaker v.
    Coleman, 
    115 F.2d 305
    , 307 (5th Cir. 1940).
    See Brunswick Corp. v. Vineberg, 
    370 F.2d 605
    , 612 (5th Cir. 1967) ("Summary
    judgment is a lethal weapon, and courts must be mindful of its aims and targets and
    beware of overkill in its use.").
    Even in Perma Research, the case that serves as the beginning of the sham
    affidavit doctrine, the court determined that trial judges cannot "'exclude the [offsetting]
    affidavit[s] from consideration in the determination of the question whether there is any
    genuine issue as to any material fact'" and acknowledged that "there may be some
    instances where summary judgment is too blunt a procedural device." 
    410 F.2d at 578
    .
    Finding an affidavit is a sham and striking its consideration requires a two-part
    inquiry. First, the court determines whether a contradiction exists. Second, the court
    determines whether the contradiction is justified. The court must consider the contents
    and the context of the prior testimony. As a result, some courts, ours included, have been
    reluctant to blindly apply the sham affidavit doctrine without reviewing the contents and
    the context of the affidavit and the testimony in detail. They urge a more flexible
    approach. See Webster v. Sill, 
    675 P.2d 1170
    , 1173 (Utah 1983) ("The rule that a moving
    party may not rely upon his own affidavit which contradicts his deposition must be
    administered with care. It is common knowledge that witnesses sometimes misstate
    themselves, may not properly understand the question propounded, or give equivocal
    answers.").
    9
    We discuss the application of the sham affidavit doctrine in Kansas.
    In reviewing the cases from our Supreme Court that have applied the sham
    affidavit doctrine to strike an affidavit, it becomes apparent that the affidavits submitted
    must flatly contradict prior testimony. There have been mainly four such Supreme Court
    cases since and including Mays, the case the district court relied on here. All found the
    affidavits to be contradictory and affirmed the district court's failure to consider them in
    ruling on a summary judgment motion. Because they are all very fact specific it is
    necessary to review them in detail.
    Mays, 
    233 Kan. 38
    , involved a personal injury lawsuit brought after a gas pipeline
    explosion. Mays was the only eyewitness to the movement and rupture of the pipeline
    which caused his injuries. He testified during a deposition that the pipe broke within 5
    feet either side of the steel-to-fiberglass connection. Five feet on the gas well side would
    be the fiberglass pipe manufactured by the Ciba-Geigy Corporation, one of the
    defendants in the lawsuit. But 5 feet on the separator side would be steel pipe, not
    manufactured by Ciba-Geighy. The defendant Doc Dale, through his company Doc's
    Backhoe Service, bought and installed materials that led to the explosion. He testified in
    his deposition about his own extensive knowledge and experience in hooking up oil and
    gas wells, that he did not read the package inserts related to making the bond of steel to
    fiberglass connections because he knew what he was doing.
    Three years later—after the defendants moved for summary judgment—Mays
    submitted affidavits that directly contradicted this prior testimony. In particular, Mays'
    affidavit now stated that the pipe broke 5 feet into the fiberglass side of the connection
    (which would be Ciba-Geigy responsibility) and Dale's affidavit stated he would have
    performed all the steps properly and the explosion could have been avoided if he had
    been adequately instructed by the defendants. The trial court struck these affidavits as
    contradictory. On appeal, our Supreme Court concluded that the affidavits were in direct
    10
    response to the filing of the summary judgment motions and were intended to contradict
    the prior depositions in order to defeat summary judgment. 
    233 Kan. at 46-47
    .
    In Bacon v. Mercy Hosp. of Ft. Scott, 
    243 Kan. 303
    , 
    756 P.2d 416
     (1988), the
    court faced expert testimony about the cause of a newborn's post-birth oxygen
    deprivation which the Bacons claimed in their medical malpractice action caused the
    baby's cerebral palsy. There had also been pre-birth oxygen deprivation when the cord
    was found wrapped around the baby's neck. Causation was the main issue in the case.
    The Bacons had two causation experts, Dr. Judith Wood and Dr. Buck. It was undisputed
    that the presentation of the case turned on the testimony of experts. During Dr. Buck's
    deposition, he stated that it would require a pediatric neurologist to determine the actual
    cause of the baby's cerebral palsy and he was simply an obstetrician. Dr. Wood testified
    that she had never attended a child with cerebral palsy, had never been asked to diagnose
    it, and was not an expert in its etiology. She could not state within a reasonable degree of
    probability that the care and treatment of the defendant doctor caused cerebral palsy in
    the child.
    After the district court granted summary judgment for the defendants for failure to
    establish causation, the Bacons moved to alter or amend the judgment. This time, the
    Bacons presented affidavits from both doctors. Dr. Buck's affidavit swore he believed
    that the lack of oxygen after delivery caused the newborn's cerebral palsy. Dr. Wood's
    affidavit swore that the stress inflicted on the baby after birth increased the severity of her
    cerebral palsy. The court refused to consider the affidavits and the Bacons appealed. The
    Supreme Court found the district court's decision was correct because a party may not
    remain silent in the face of a motion for summary judgment and later claim there is more
    evidence to support its claims. It then cited Mays for the proposition that an affidavit
    cannot be used to controvert a prior sworn statement in order to create an issue of
    material fact and defeat a motion for summary judgment. 
    243 Kan. at 314
    .
    11
    P.W.P., 
    266 Kan. 417
    , involved a patient who sued her therapist and the Johnson
    County Mental Health Center claiming that the therapist negligently entered into a sexual
    relationship with her beginning in 1985 that caused her substantial emotional damage.
    The case ended up being dismissed on the statute of limitations. The issue was when
    P.W.P. could have first reasonably learned about her injury to begin the statute of
    limitations clock. She testified in her deposition that she knew of her cause of action and
    her injury by 1985 and 1986 based on deposition testimony and letters she had written.
    She did not sue until 1995, well beyond the two-year statute of limitations. See K.S.A.
    60-513(a)(4), (7). But in response to the defendants' motion for summary judgment,
    P.W.P. submitted an affidavit that, contrary to her testimony, for the first time claimed
    that because of flashbacks she experienced she may not have written the letters until 1993
    or 1994. The Supreme Court affirmed the district court's decision to disregard the
    affidavit citing both Bacon and Mays and the doctrine that "'[a]n affidavit cannot be used
    to controvert a prior sworn statement in order to create an issue of material fact and
    defeat a motion for summary judgment.'" 
    266 Kan. at 431
    . We note that her petition
    alleged the harm began in 1985 as well.
    In Dawson, 
    276 Kan. 373
    , a patient sued a resident psychiatrist at the Menninger
    Clinic, Dr. Sandra Prager, alleging negligence and other wrongs in her psychiatric care.
    She also claimed that Menninger failed to adequately supervise Dr. Prager. Dawson
    designated an expert witness, Dr. Robert Simon. The applicable statute requires that a
    person cannot be qualified as an expert unless the expert has devoted at least 50% of such
    person's professional time within the previous two years to the actual clinical practice in
    the same profession which the defendant is licensed. K.S.A. 60-3412. Dr. Simon testified
    in his deposition that he spent less than half his time in actual clinical practice. When
    Prager moved for summary judgment because Dawson's only expert witness was not
    qualified and thus Dawson could not prove deviation from the standard of care, Dawson
    filed an affidavit from Dr. Simon stating, in contradiction to his extensive deposition
    testimony, that his clinical practice for the preceding two years exceeded 50%. He then
    12
    sought to explain the discrepancy by arguing that his testimony during his deposition was
    only in response to the time he spent in clinical practice as defined by defense counsel.
    But as the court analyzed the new information in the affidavit it determined that the
    estimations in his affidavit only amounted to another quarter of an hour a week, which
    did not put him over the 50% minimum. So even if the court considered the affidavit, it
    still did not support his 50% claim. Our Supreme Court affirmed the striking of the
    affidavit and the issuance of summary judgment for Prager. 
    276 Kan. at 385-86
    .
    As cited by the district court here, our court has also recognized the sham affidavit
    doctrine, although we did not identify it as such.
    Lana Smith, an at-will employee, had a dispute with the medical practice she
    worked for over whether they promised her a $10,000 bonus. The primary issue in the
    case was whether the bonus was just for the first year of Smith's employment or for later
    years as well. Smith, 
    49 Kan. App. 2d 812
    . In her deposition testimony, Smith said that
    she recalled no one telling her that the bonus was limited to her first year of employment.
    The medical practice presented testimony from its business manager, Liz Tolberd, that
    she told Smith the bonus was limited to the first year. In response to a motion for
    summary judgment, Smith filed an affidavit contending that Tolberd falsely stated that "I
    agreed to 'a bonus guarantee of $10,000 for the first year.'" 49 Kan. App. 2d at 818-19.
    The district court refused to consider the affidavit, in essence relying on the sham
    affidavit doctrine. We affirmed holding that "[t]o go from saying that she didn't recall
    Tolberd limiting the bonus guarantee to the first year, to saying that Tolberd had testified
    falsely was more than a subtle shift, and the new position came only in response to a
    summary-judgment motion." 49 Kan. App. 2d at 819. We noted all Smith had was a
    subjective expectation that her bonus would continue and under the facts that was not
    enough to avoid summary judgment. 49 Kan. App. 2d at 819.
    13
    Likewise, the plaintiffs' claims in Deters, 
    56 Kan. App. 2d 1170
    , were dismissed
    on summary judgment. The Deters' underlying claim was whether the negligence of the
    electric company in negligently wiring their generator causing the failure of their heat
    pumps. But the decision rested on whether the statute of repose had expired, defeating the
    Deters' claim. Stephen Deters testified in his deposition that electric company workers
    were at his home in the mid-2000s to address blinking lights, but he had no memory of a
    service call to his house when the electric company employees would have worked on his
    generator (the devise that he claims malfunctioned to cause his heat pumps to fail). The
    electric company claimed it last worked on the generator in 1997, more than 15 years
    before the Deters' lawsuit was filed in 2015. But in his affidavit in response to the electric
    company's summary judgment motion, Stephen claimed that he watched electric
    company employees work on the generator in 2007 and that they checked the connections
    in 2007, which he understood to mean they worked on the generator. We affirmed the
    district court's grant of summary judgment finding that Stephen's affidavit was not only
    self-serving and contradictory to his prior testimony, but was conclusory, flimsy,
    transparent, and was based on an inference or speculation. 56 Kan. App. 2d at 1185. So
    the fact that the affidavit was more than just contradictory provides limited support for
    the district court to rely on it for any rule regarding sham affidavits applicable rule in this
    case.
    Each case represents affidavits that contradicted the plaintiffs' initial claims and
    testimony. But this does not mean that the court will automatically classify every
    affidavit presented that varies at all from deposition testimony a sham affidavit and
    exclude it from consideration. Our court, as well as others, have recognized that the court
    can consider an affidavit if the litigant did not submit it to create a dispute of fact but
    merely supplements, clarifies, or amplifies prior testimony.
    14
    Even in Mays, our Supreme Court recognized that a court is not required to strike
    all affidavits that vary from deposition testimony by citing—but distinguishing—
    Kennett-Murray Corp. v. Bone, 
    622 F.2d 887
     (5th Cir. 1980). Mays, 
    233 Kan. at 45
    .
    In Kennett-Murray, an employer sued a former employee to recover on a
    promissory note and an employment contract. One of the main issues was whether
    Kennett-Murray personnel had made fraudulent representations to induce Bone into
    signing a new employment contract when his prior contract expired. During his
    deposition Bone admitted that he never read the contract because he thought it was the
    same as his prior contract. At one point he testified that the Kennett-Murray employee
    who asked him to sign the new contract said nothing about the promissory note the
    company claimed was due or the new contract, thus negating any potential claims for
    fraudulent misrepresentation. But Bone later testified that he was led to believe it was the
    same contract because the employee said it was and he was led to believe certain things
    about the carryover of the promissory note. In response to Kennett-Murray's summary
    judgment motion, Bone submitted an affidavit that said the Kennett-Murray employee
    told him "'something to the effect that this contract would serve to renew my first contract
    and that they were just alike or that they were the same contract.'" 
    622 F.2d at 891
    .
    The Fifth Circuit reversed the district court's decision striking the affidavit as
    inconsistent with his deposition testimony. The court recognized first that the defendant's
    answer to the petition alleged that personnel at Kennett-Murray told him that the money
    represented by his promissory note "'would go back into the Linden operation'" and not
    be Bone's obligation. He also asserted that this representation was false and material. 
    622 F.2d at 890-91
    . As for to the employment contract, he alleged in his answer that Kennett-
    Murray personnel advised him that it was the same as his earlier agreement. So even
    though he did not read it Kennett-Murray induced him by this false and material
    representation.
    15
    Moreover, although the Fifth Circuit recognized the sham affidavit doctrine set out
    in Perma Research, it held that not every discrepancy in an affidavit justifies a district
    court's refusal to give credence to such evidence. "Bone's affidavit did not purport to raise
    a new matter, but rather to explain certain aspects of his deposition testimony." Kennett-
    Murray, 
    622 F.2d at 894
    . It found Bone's assertion plausible and not inherently
    inconsistent. The court noted that in context, Bone's statement in his deposition could not
    be taken literally. It also noted that Bone's affidavit did not undermine his general theory
    of defense, nor was it a reformulation of it. 
    622 F.2d at 894-95
    . "While some statements
    in Bone's deposition differ with those in his affidavit, these conflicts present questions of
    credibility which require jury resolution." 
    622 F.2d at 895
    .
    This court has recognized the same limits to the sham affidavit doctrine as
    Kennett-Murray.
    A legal malpractice claim was at issue in Zimmerman v. Brown, 
    49 Kan. App. 2d 143
    , 
    306 P.3d 306
     (2013). Daniel and Sara Zimmerman brought a claim against their
    attorney, Richard Brown, related to the sale of their business to him. There was a concern
    that by selling the business and buying a competing business the Zimmermans would
    violate a noncompete agreement. Brown was also involved in the Zimmermans' business
    and likewise wanted to buy into the new business, and likewise feared the ramifications
    on his income from the old business as a result of a noncompete agreement. So he
    recommended the Zimmermans sell the business to him to avoid detection. Eventually
    the whole sham unraveled, Brown stopped paying the Zimmermans as they had agreed
    and the Zimmermans sued. Although the facts are significantly more complicated than
    that, for our purposes it is safe to conclude that Brown argued he was not responsible for
    legal malpractice based on his defense of in pari delicto—the principle that a plaintiff
    who participated in equal wrongdoing with the defendant may not recover damages from
    the defendant resulting from the wrongdoing. 49 Kan. App. 2d at 150. Brown argued that
    this was a complete defense and entitled him to summary judgment. But the Zimmermans
    16
    contended in an affidavit in opposition to summary judgment that they never believed
    they were doing anything morally or ethically wrong when they sold their business "on
    paper only" to Brown. 49 Kan. App. 2d at 152-53. Brown argued that in Daniel's
    deposition he admitted his involvement in this scheme. So the court should strike any
    affidavit to the contrary as a sham affidavit. The district court granted summary judgment
    necessarily disregarding the Zimmermans' affidavit.
    Our court, citing Mays and Bacon reversed the district court and held that Daniel's
    statements were "not the sort of contradictory sworn statements that Kansas courts have
    held insufficient to avoid summary judgment." 49 Kan. App. 2d at 153. In finding that
    this was not sham testimony the court held that there was no contradiction between a
    claim that they were trying to avoid detection by their existing business to avoid being
    charged with violation of the noncompete agreement and a belief—based on the advice of
    their attorney—that they were in fact violating the agreement. They were avoiding
    detection to avoid disputes, not conceding they were in violation. 49 Kan. App. 2d at
    153-54.
    In Bird v. Kansas Dept. of Transportation, 
    23 Kan. App. 2d 164
    , 
    928 P.2d 915
    (1996), the court faced a summary judgment motion in a wrongful death case. Judy Bird
    was killed in a one-vehicle collision with a guardrail. The Kansas Department of
    Transportation (KDOT) argued it was immune from prosecution under the Kansas Tort
    Claims Act. KDOT argued that no prevailing engineering standards existed for designing
    and installing guardrails when it installed this particular guardrail. Without those
    standards, their design and installation were a discretionary function and KDOT was
    immune from liability.
    The Birds submitted several affidavits in response to KDOT's motion for summary
    judgment. Those included portions of expert witness depositions establishing that even
    under 1972 standards guardrails had to be a certain height. The guardrails here were
    17
    above the height allowing them to penetrate the passenger compartment of the car. They
    also presented depositions from a KDOT official regarding department policy to install
    rumble strips on the shoulder, which were not present in this case. But the district court
    disregarded the affidavits finding that they "'controvert, contradict, add to, and attempt to
    further explain'" the deposition testimony of the expert witnesses and granted summary
    judgment. 
    23 Kan. App. 2d at 169
    . This court reversed, finding that the Birds' affidavits
    did not "show such contradictions or inconsistencies as would warrant disregarding the
    affidavits" under Mays and Bacon. 
    23 Kan. App. 2d at 169
    . The opinion does not set out
    the exact way the depositions were contradictory. But again, our court recognized that the
    application of Mays and Bacon are not automatic and are fact and context dependent.
    Two individuals involuntarily committed to the Kansas Sexually Violent Predator
    Treatment Program brought a civil rights action against the Secretary of Kansas Social
    and Rehabilitation Services in Brull v. Jordan, No. 101,755, 
    2011 WL 420700
     (Kan.
    App. 2011) (unpublished opinion). As here, the question in the case was whether the
    district court properly granted a summary judgment motion, but the panel also briefly
    discussed whether affidavits submitted by the plaintiffs were so-called "sham affidavits"
    that could not be used to avoid summary judgment. 
    2011 WL 420700
    , at *8. Relying in
    part on Mays, the panel concluded that the plaintiffs' prior responses to interrogatories
    "merely summarized the alleged violations [and] did not purport to provide every fact
    that might be relevant." 
    2011 WL 420700
    , at *8. Thus, even though the affidavits
    provided more specific information, the panel "[found] nothing in the affidavits that so
    conflicts with a prior response that the affidavits should be considered sham affidavits for
    summary-judgment purposes." 
    2011 WL 420700
    , at *8. We are at a bit of a loss because
    the opinion does not specifically explain how the affidavits varied from the answers to
    interrogatories, but the case recognizes that the supplementing or amplifying of prior
    answers does not necessarily a sham affidavit make.
    18
    And finally, in K.F.B. Ins. Co. v. Caswell, No. 62,155, unpublished opinion filed
    April 14, 1989 (Kan. App.), the defendant made a sworn statement to the insurance
    company that he was acting outside the scope of his employment when the fatal collision
    which was the subject of the litigation occurred. Later, after the insurance company
    moved for summary judgment, the defendant submitted an affidavit recanting that prior
    statement. The trial court ruled that the plaintiff's motion for summary judgment could
    not be supported by a statement made before litigation and considered the affidavit. The
    panel agreed that the district court could consider the affidavit since the defendant did not
    submit the affidavit to create a dispute of fact or defeat summary judgment, but because
    his answer to the initial petition placed permissive use of the vehicle in dispute.
    Christiansen also relies on at least six cases from outside of the Kansas appellate
    system. We will not discuss each of them, but they do support Christiansen's position that
    affidavits can clarify or amplify facts and courts should not consider them sham
    affidavits. See Pambianchi v. Arkansas Tech. Univ., 
    95 F. Supp. 3d 1101
    , 1113-14 (E.D.
    Ark. 2015) (affidavit can generate an issue of fact if it does not propose to raise a new
    matter, but rather to explain certain aspects of previous testimony or if confusion
    contributed to the inconsistency); In re Independent Service Organizations Antitrust
    Litigation, 
    85 F. Supp. 2d 1130
    , 1156-57 (D. Kan. 2000) (finding that the expert's
    declaration was not contradictory and "[a]t best" reflected "speculation" on the expert's
    part); Fairchild v. All-American Check Cashing, Inc., No. 2:13-CV-92-KS-MTP (S.D.
    Miss. 2014) (unpublished opinion) (allowed an affidavit to clarify or amplify facts "'by
    giving greater detail or additional facts not previously provided in the deposition'");
    Jimenez v. Flagstar Bank, F.S.B., No. SA-13-CV-186-XR, 
    2013 WL 6332128
    , at *4
    (W.D. Tex. 2013) (unpublished opinion) (while the affidavit "paraphras[ed] conversation
    and stat[ed] facts with ambiguity, this conflict raises an issue of credibility rather than
    admissibility"); C.R. Pittman Const. Co. v. National Fire Ins. Co. of Hartford, 
    453 Fed. Appx. 439
    , 443 (5th Cir. 2011) (unpublished opinion) (just because an affidavit is "self-
    serving" the court cannot exclude it as incompetent for that reason alone).
    19
    We note that Silverbrand has not addressed any of the cases cited by Christiansen.
    They have presented no argument distinguishing them from the case before us to support
    their position. A party has a duty to show why their position is sound despite contrary
    authority. Failure to do so results in abandonment of the argument. State v. Dunham, 
    58 Kan. App. 2d 519
    , 527, 
    472 P.3d 604
     (2020). Their stated reason for not addressing the
    cases is a misguided belief that Christiansen improperly included copies of the opinions
    in the appendix to her brief. But Supreme Court Rule 7.04(g)(2)(C) (2021 Kan. S. Ct. R.
    46) requires Christiansen to attach any unpublished memorandum opinions "to any
    document, pleading, or brief that cites the opinion." Christiansen acted appropriately by
    attaching copies of the unpublished decisions cited in her brief in the appendix. Contrary
    to Silverbrand's assertion, Christiansen did not attach any published opinions. They
    ignore Christiansen's arguments at their own peril.
    The district court abused its discretion in striking the affidavit, and Christiansen shows a
    genuine dispute of material fact to preclude summary judgment.
    We conclude that the district court made an error of fact and law and therefore
    abused its discretion in striking the affidavits in this case. The law is clear, an affidavit
    submitted along with a response to a motion for summary judgment does not contradict
    prior testimony when offered to provide clarification or expand on a previous sworn
    statement. Christiansen's previous statements about slipping on the ice and falling were
    fairly nondescriptive. Her affidavit sought to clarify that she slipped on the ice when
    exiting the vehicle but that a crack/pothole in the parking lot was a major contributing
    factor in causing her to fall and break her ankle. It also bears mentioning that
    Christiansen has never denied slipping on the ice, suggesting that she was not trying to
    contradict her prior testimony since the mere fact of having slipped on ice weakens her
    claim against Silverbrand. And likewise, Christiansen has never claimed that she was not
    injured as a result of her foot landing in the pothole. At most her answers were
    incomplete, not contradictory. As a result, we find that Christiansen's affidavit did not
    20
    contradict her prior testimony but merely explained the facts surrounding the accident in
    more detail.
    We recognize, as the district court noted, that Christiansen had at least two
    opportunities to expound upon the cause of the accident. First, in Interrogatory No. 5,
    Silverbrand directly asked her to "[p]lease describe in detail how the injury occurred."
    Yet Christiansen's response mentioned only her actions preceding the accident and
    simply that "my right foot slid on ice and I fell down." But in her subsequent deposition,
    Christiansen was only asked whether she agreed with the statement that she slipped on
    the ice. She did. Neither response contradicted her claim in her affidavit that she slipped
    on the ice but the existence of the pothole caused her to break her ankle. Christiansen has
    always alleged from her initial petition that "[her] shoe got caught in a large pothole
    causing her to fall to the ground" and sustain injuries. She alleged that due to lack of
    maintenance the parking lot was "uneven, deteriorated, pock marked with holes, and
    rough" and "[d]ue to years of neglect and lack of maintenance, the surface was
    unreasonably dangerous." She provided pictures of the condition of the parking lot to
    Silverbrand as part of discovery. She also has always alleged that "[t]he direct and
    proximate cause of [her] injuries and damages" was the negligence of Silverbrand. The
    clarification in her affidavit would have come as no surprise.
    The nonmoving party is not required to prove their case at the summary judgment
    stage but must come forward with specific facts supporting their claim. Drouhard-
    Nordhus, 301 Kan. at 623. Likewise, this court must resolve facts and reasonable
    inferences in Christiansen's favor as the nonmovant. GFTLenexa, LLC, 310 Kan. at 982.
    Unlike in Bacon and Mays, Christiansen's photos and statement about the cause of her
    injury are more than mere speculation and raise a genuine dispute of material fact. As a
    result, we find that the district court erred in granting Silverbrand's motion for summary
    judgment and reverse that ruling and remand for further proceedings.
    21
    Reversed and remanded with directions.
    ***
    ATCHESON, J., concurring: The sham affidavit doctrine has been a cog in civil
    procedure machinery across state and federal courts for decades. Kansas is no exception,
    having recognized a form of the rule more than 50 years ago. Basically, the rule
    precludes a party from defeating a motion for summary judgment by submitting an
    affidavit from a witness that contradicts facts in testimony or a sworn statement of the
    witness submitted in support of the motion. The later conflicting affidavit typically will
    be treated as a "sham" ginned up solely to create a phony dispute about a material fact
    and will be disregarded as such. See Mays v. Ciba-Geigy Corp., 
    233 Kan. 38
    , 46-47, 
    661 P.2d 348
     (1983). The rule, however, doesn't bar an affidavit that legitimately explains or
    elaborates on the earlier representations or offers a bona fide explanation for an apparent
    contradiction. 
    233 Kan. at 44
     (evidence discovered after first statement may prompt
    legitimate revision in later affidavit); at 45 (confusing or incomplete questioning in
    deposition generating first statement permits later clarification); at 46 (second more
    expansive statement does not create actual conflict).
    In a common scenario, plaintiffs opposing defendants' summary judgment motions
    will offer their own affidavits that differ on a relevant factual point from their deposition
    testimony used to support the motions. Summary judgment, of course, ought not be
    granted if there is a genuine dispute about one or more material facts. See Siruta v.
    Siruta, 
    301 Kan. 757
    , 766, 
    348 P.3d 549
     (2015); Doe H.B. v. M.J., 
    59 Kan. App. 2d 273
    ,
    294, 
    482 P.3d 596
     (2021). So the district court faces a threshold issue: Should the
    plaintiff's affidavit be considered at all in ruling on the summary judgment motion. Here,
    the Barton County District Court refused to consider Plaintiff Anita Christiansen's
    affidavit explaining the mechanics of her slip-and-fall injury in the parking lot of the
    United States Postal Service building where she worked as a letter carrier. She sustained
    22
    a severe break of her right ankle. As the parties have framed the governing legal issue for
    us, if the proximate cause of Christiansen's injury was the ice in the parking lot, then the
    Postal Service is liable. But if the proximate cause was a negligent failure to repair
    obvious defects in the parking lot, then the Silverbrand defendants would be liable.
    In her petition, Christiansen alleged the parking lot was in poor repair and that
    "[her] shoe got caught in a large pothole causing her to fall to the ground" and she
    "sustained personal injuries and damages" as a result. The defendants served
    interrogatories on Christiansen asking, among other things, for her to "describe in detail
    how the injury occurred." In her written answer, Christiansen responded, in part, "[M]y
    right foot slid on ice[,] and I fell down." She did not mention a pothole or any other
    defect in the surface of the parking lot. The defendants' lawyer took what could be
    characterized as a terse (or, perhaps, perfunctory) deposition of Christiansen. He asked
    her to confirm that she told the ambulance personnel and the physician who treated her at
    the emergency room that she slipped on the ice. Christiansen agreed both that she,
    indeed, slipped on the ice and told medical providers as much. But the lawyer never
    asked Christiansen to describe the actual mechanics of her injury, to elaborate on the
    allegation in the petition, or to explain the ostensible discrepancy between that allegation
    and her interrogatory response.
    Defendants filed a motion for summary judgment, relying on Christiansen's
    interrogatory answer and deposition testimony to demonstrate that the ice was the sole
    proximate cause of her broken ankle. In support of her memorandum in opposition to
    summary judgment, Christiansen signed an affidavit stating that "[m]y right foot started
    sliding on ice. . . . and then my foot caught the edge of a large crack/pothole in the
    parking lot." In the affidavit, Christiansen explained that she heard and felt her ankle
    "snap" when her shoe caught in the pothole. The district court cited the sham affidavit
    rule and refused to consider the affidavit and granted the defendants' motion for summary
    judgment.
    23
    We review the district court's ruling disregarding Christiansen's affidavit for an
    abuse of discretion. A district court exceeds that discretion if it rules in a way no
    reasonable judicial officer would under the circumstances, if it ignores controlling facts
    or relies on unproven factual representations, or if it acts outside the legal framework
    appropriate to the issue. See Biglow v. Eidenberg, 
    308 Kan. 873
    , 894, 
    424 P.3d 515
    (2018); Northern Natural Gas Co. v. ONEOK Field Services Co., 
    296 Kan. 906
    , 935, 
    296 P.3d 1106
     (2013).
    Although now almost 40 years old, the detailed discussion of the sham affidavit
    rule in Mays remains the governing pronouncement of the rule in Kansas and continues to
    reflect generally accepted contours of the doctrine. See Boykin v. Family Dollar Stores of
    Michigan, LLC, 
    3 F.4th 832
    , 842-43 (6th Cir. 2021); James v. Hale, 
    959 F.3d 307
    , 315-
    17 (7th Cir. 2020); 73 Am. Jur. 2d Summary Judgment § 57. In Mays, the court identified
    Powell v. City of Haysville, 
    203 Kan. 543
    , 549, 
    455 P.2d 528
     (1969), as the rule's
    fountainhead in Kansas. 
    233 Kan. at 44-45
    . The doctrine extends beyond deposition
    testimony and covers interrogatory answers given under oath, too. See Robles v.
    Agreserves, Inc., 
    158 F. Supp. 3d 952
    , 981 (E.D. Cal. 2016); Estrada v. US Bank, N.A.,
    No. 2:18-cv-01361-RGK-AMF, 
    2018 WL 8785205
    , at *2-3 (C.D. Cal. 2018)
    (unpublished opinion); Dunavant v. Frito Lay, No. 1:11-0028, 
    2013 WL 816673
    , at *4
    (M.D. Tenn. 2013) (unpublished opinion).
    There is no fully predictive test to determine in the abstract when an affidavit
    submitted in opposition to summary judgment should be considered an impermissible
    attempt to defeat the motion by contradicting the affiant's earlier sworn statements. The
    determination is inevitably contextual and depends upon the substantive issue asserted as
    the basis for summary judgment, the factual content of the original statement offered in
    support of the motion, the scope of the conflict or discrepancy between that statement and
    the challenged affidavit, and any reasons given for the ostensible change. The conclusion
    effectively depends upon the overall circumstances of the particular case. 10A Wright,
    24
    Miller & Kane, Fed. Prac. & Proc. Civil § 2726.1 (4th ed. 2021). As such, the assessment
    has much in common with Justice Potter Stewart's analytical model for hardcore
    pornography: "I know it when I see it." Jacobellis v. Ohio, 
    378 U.S. 184
    , 197, 
    84 S. Ct. 1676
    , 
    12 L. Ed. 2d 793
     (1964) (Stewart, J., concurring).
    Here, we are in as good a position as the district court to assess the
    inconsistencies, such as they are, between Christiansen's interrogatory answer and
    deposition transcript, on the one hand, and her later affidavit, on the other, since they are
    immutable documents. And we may then determine their legal effect for summary
    judgment purposes. See Thoroughbred Assocs., L.L.C. v. Kansas City Royalty Co., 
    297 Kan. 1193
    , 1207, 
    308 P.3d 1238
     (2013).
    Here, the district court misapplied the governing legal framework of the sham
    affidavit rule. Christiansen's affidavit did not contradict her deposition testimony. In both,
    she acknowledged slipping on the ice. The affidavit expanded on the cause of her fall to
    explain how in an immediate and continuous sequence she broke her ankle when her foot
    met the pothole. During the deposition, defendants' lawyer never asked Christiansen to
    describe how she injured her foot. Had he examined her in detail on that point,
    Christiansen's omission of any mention of catching her shoe in a pothole likely would
    have rendered her later affidavit a sham submission.
    In the deposition, the lawyer merely confirmed that Christiansen told the
    ambulance and emergency room medical personnel she slipped on the ice. Christiansen
    provided that description just after the incident, while she was in considerable pain, to
    generically explain her injury as a slip-and-fall. That she didn't describe each sequential
    step leading to her broken ankle seems unremarkable in context. But more to the point, it
    doesn't create a conflict of the kind the sham affidavit rule is intended to reach.
    Christiansen's explanation for medical personnel could, of course, be juxtaposed with her
    affidavit for the fact-finder's consideration at trial.
    25
    In isolation, Christiansen's answer to the interrogatory poses a closer question. The
    question sought a detailed explanation of how she injured her ankle. The response doesn't
    mention Christiansen catching her shoe in the pothole—something fairly considered more
    than an incidental aspect of the injury. But the defendants' lawyer did not question
    Christiansen about the answer during her deposition. And he shouldn't have been
    surprised by the affidavit in light of the allegations in the petition. On balance and in the
    context of the pretrial discovery as a whole, I don't see a sufficient discrepancy to bar the
    affidavit as a sham.
    We need say no more, and I do not. I concur in the result reversing the summary
    judgment for the defendants and remanding for further proceedings.
    26
