Analysis

A model's reading — qwen3.8-27b, prompt v1, 2026-10-13T03:14Z · confidence high

The trial court excluded photographs of a subsequent remedial measure and precluded the plaintiff from arguing in closing that the defendant should have moved a wet wipe stand, finding the theory was not disclosed and lacked evidentiary support. The Court of Appeal affirmed, holding the trial court did not abuse its discretion in excluding the evidence under Evidence Code section 1151 and limiting closing arguments, and further found no prejudice.

Ruling reviewedStandardThe courtThe model
Exclusion of three photographs showing the defendant moved the wet wipe stand outside after the accident.
“Because Melendez has not shown that Stater Brothers contested the feasibility of moving its wet wipe stand outside its store, the trial court properly exercised its discretion when it excluded the photographs of the company’s alleged subsequent remedial measure.”
abuse of discretioncorrectagree with court
The court correctly applied the abuse of discretion standard and relied on established California law (Ault, Baldwin) that subsequent remedial measures are admissible for feasibility only when the defendant contests feasibility. The record showed the defendant did not formally contest feasibility, making the exclusion proper.

“Because Melendez failed to disclose her theory of liability prior to trial, the court properly excluded argument on that theory.”
abuse of discretioncorrectagree with court
The court correctly identified that the trial court has broad latitude to limit closing arguments and that the plaintiff failed to provide notice of this new theory in discovery or the complaint. The court also correctly applied the harmless error standard, noting the jury's swift verdict despite the plaintiff's attempts to argue the point.

Authorities

  • relied: Ault v. International Harvester Co. (1974) 13 Cal.3d 113 — Evidence of subsequent repairs is relevant to negligence if it illustrates feasibility, but the exclusionary rule is retained for public policy reasons to encourage safety improvements.
  • relied: Alcaraz v. Vece (1997) 14 Cal.4th 1149 — Section 1151 excludes evidence of subsequent remedial measures only when offered to prove negligence or culpable conduct.

  • relied: Paige v. Safeway, Inc. (2022) 74 Cal.App.5th 1108 — In civil cases, prejudice from error must be affirmatively demonstrated by the appellant; it is not presumed.

The appellate opinion: sound — The opinion is sound because it correctly applies the specific requirements of Evidence Code section 1151 regarding the admissibility of subsequent remedial measures for feasibility, and it properly upholds the trial court's management of the trial by preventing 'trial by ambush' through undisclosed theories. The harmless error analysis is also robust, citing specific instances where the plaintiff's counsel attempted to argue the excluded theory despite the ruling.

A model's reading — claude-fable-5-1, prompt v1, 2026-10-13T04:29Z · confidence medium

After a jury found Stater Bros. not negligent in a slip-and-fall on a discarded disinfectant wipe, the trial court had excluded photographs showing the store later moved its wipe stand outside (as an uncontested-feasibility subsequent remedial measure under Evidence Code section 1151, and alternatively under sections 210 and 352) and barred closing argument that the stand should have been relocated, a theory not pleaded or disclosed in discovery. The Court of Appeal reviewed both rulings for abuse of discretion, found none, held any error in limiting closing argument harmless given counsel's repeated references to the stand's location and the swift 11–1 defense verdict, and affirmed.

Ruling reviewedStandardThe courtThe model
Exclusion of three photographs of the relocated wet wipe stand as evidence of a subsequent remedial measure under Evidence Code section 1151 (feasibility exception inapplicable because feasibility not contested)
“Because Melendez has not shown that Stater Brothers contested the feasibility of moving its wet wipe stand outside its store, the trial court properly exercised its discretion when it excluded the photographs of the company’s alleged subsequent remedial measure.”
abuse of discretioncorrectagree with court
Section 1151 bars subsequent-remedial-measure evidence only when offered to prove negligence (Alcaraz; Ault), and the feasibility exception is recognized in Baldwin Contracting and Dincau. The court's added requirement that feasibility be actually contested rests on thin California authority (an appellate department opinion, a Court of Appeal case on different facts, the Ault dissent, and a Ninth Circuit case applying FRE 407's express 'if controverted' language, which section 1151 lacks), and Black's testimony that placing the stand outside 'makes no sense' arguably did dispute feasibility. Still, under the deferential standard, with the trial court's unchallenged section 352 alternative ground and the lay-opinion character of Black's testimony, the result is defensible.
Refusal to allow the photographs to be used to impeach former store manager Black
“The court found the photographs did not impeach Black, as he no longer worked at the store and had merely expressed an opinion that, “for [him], it’s unsafe” to place the wet wipe stand outside.”
unclearnot reachedunsure
The appellate court framed Melendez's challenge solely as a feasibility argument and did not separately analyze the impeachment theory, even though Black also testified he did not recall the stand ever being placed outside. Because the opinion does not say whether Melendez pressed impeachment on appeal, and Black's lack of personal knowledge after leaving the store limits impeachment value, I cannot say the trial court erred.
Alternative grounds for excluding the photographs under Evidence Code sections 210 (relevance) and 352
“Given our conclusion that the trial court properly excluded the photographs under section 1151, it is unnecessary for us to decide whether Melendez forfeited her challenge to the evidentiary ruling by failing to address the trial court’s alternative findings that the evidence was irrelevant”
abuse of discretionnot reachedagree with court
The appellate court expressly declined to decide whether Melendez forfeited her challenge by not attacking these independent grounds, citing David v. Medtronic. The unchallenged section 352 ruling independently supports affirmance of the evidentiary ruling, which strengthens the overall result even if the section 1151 analysis is debatable.
Order (construed from a partial directed verdict motion as a motion in limine) precluding closing argument that Stater Bros. should have moved the wet wipe stand
“Because Melendez failed to disclose her theory of liability prior to trial, the court properly excluded argument on that theory.”
abuse of discretionharmless erroragree with court
Trial courts have broad latitude over the scope of closing argument (Edwards; Code Civ. Proc. § 128(a)(3)), counsel may not argue facts not in evidence (Dhaliwal), and the complaint and contention-interrogatory response disclosed only a failure-to-clean theory, so the undisclosed stand-location theory could properly be barred (Deyo; Duchrow). The court held the ruling correct and alternatively harmless under the Paige/reasonable-probability standard; the harmlessness finding is well supported because counsel repeatedly argued the location theory anyway and the jury returned an 11–1 defense verdict within hours.

The appellate opinion: sound with gaps — The opinion reaches a defensible result under the deferential abuse-of-discretion standard and persuasively explains why the undisclosed stand-location theory could be kept out of closing argument and why any error was harmless. It has gaps, however: the 'contested feasibility' limitation on section 1151's feasibility exception is supported mainly by an appellate department opinion, a dissent, and a Ninth Circuit case construing FRE 407's express 'if controverted' language absent from section 1151, and the court did not address the impeachment theory or the unchallenged section 352 ground that would have more cleanly supported affirmance.

COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

THERESA MELENDEZ, D086334

Plaintiff and Appellant, (Super. Ct. No. CIVSB2119468)

v. STATER BROS. MARKETS, Defendant and Respondent.

APPEAL from a judgment of the Superior Court of San Bernardino County, Stephanie Thornton-Harris, Judge. Affirmed. Lew-Stevens, Steven B. Stevens; Jacoby & Meyers, and Shane V. Hapuarachy for Plaintiff and Appellant. Varner & Brandt, Angelica A. Samaniego, Treashal K. Parmar, and Grant A. Reader for Defendant and Respondent.

I INTRODUCTION Theresa Melendez slipped and fell on a disinfectant wet wipe that had been discarded on the floor of a Stater Brothers Markets (hereafter, Stater Brothers) supermarket. She appeals a judgment entered in favor of Stater 1 Brothers after a jury found that the company was not liable to her on theories of negligence and premises liability. On appeal, Melendez claims the trial court abused its discretion by excluding from evidence three photographs showing that Stater Brothers had moved the location of its disinfectant wet wipe stand at some point during the four-year period between her accident and trial. Relatedly, she argues the court erred by precluding her trial counsel from arguing to the jury in closing that Stater Brothers should have moved the location of its wet wipe stand. We reject these arguments and affirm the judgment. II BACKGROUND A. Factual Background Stater Brothers operates a chain of supermarkets in California. On August 29, 2020, Melendez entered a Stater Brothers supermarket in Alta Loma to shop. Immediately after walking into the store, she stepped on a disinfecting wet wipe that had been discarded on the store’s white or cream-colored tile floor. Melendez slipped onto the floor, regained her footing, and finished her shopping. After the accident, she purportedly experienced neck, back, and leg pain requiring medical treatment. Surveillance camera footage showed that another customer had taken a wipe from a wet wipe station located just inside the store’s main entryway, used the wipe to disinfect a shopping cart, and discarded the wipe onto the floor of the store about seven minutes before Melendez slipped and fell. B. Procedural Background In July 2021, Melendez filed a complaint against Stater Brothers for negligence and premises liability. She alleged Stater Brothers negligently maintained its Alta Loma store by “failing to inspect and properly remove 2 disposal paper towels and spilled water which had been littered around the floor near a temporary sanitation station.” She further alleged the company should have known about “the unsafe area,” and “did nothing to fix the problem or adequately warn pedestrians about it.” 1. Opening Statements The case proceeded to trial in October 2024. On the first day of trial, the parties presented opening statements to the jury. Stater Brothers orally moved for nonsuit based on certain statements that Melendez’s trial counsel made during his opening presentation. In his opening statement, Melendez’s counsel argued to the jury that Stater Brothers could have “eliminated this specific hazard” by “moving it” outside the store, where customers could more easily see discarded disinfectant wipes on the dark-colored concrete or asphalt. He added, “[a]t my grocery store, the wipes are kept outside where the carts are.” Stater Brothers’s counsel objected on grounds that the statements were improper attorney arguments and Melendez was seemingly introducing a new theory of liability into the case—namely, that the location of the disinfectant wet wipe stand (rather than the presence of one or more wet wipes on the floor) constituted a dangerous condition. In response to this objection, Melendez’s counsel countered that Stater Brothers was on notice of this liability theory because his client’s liability expert had testified in deposition that the wet wipe stand was in a high-traffic area of the store. Although Stater Brothers withdrew its oral motion for nonsuit, the trial court nonetheless found the statements were improper and any claim based on the location of the wet wipe stand would be a “completely” new theory of liability. The court ordered Melendez’s counsel to cure his improper 3 arguments by presenting an amended opening statement to the jury, which he did. 2. Evidence of a Subsequent Remedial Measure After opening statements, the parties elicited testimony from fourteen witnesses, including Melendez and Stater Brothers employees. Relevant here, the parties procured testimony from Robert Black, who was the manager of Stater Brothers’s Alta Loma store at the time of Melendez’s accident. Black testified that he trained his employees to perform hourly sweeps of the store for slip-and-fall hazards, and to pick up any hazards they encountered during their shifts. When asked to review security camera footage of his employees performing their sweeps on the night of Melendez’s accident, Black testified that the employees were performing their sweeps appropriately. Melendez’s counsel then questioned Black about the placement of the wet wipe stand. He asked Black whether a discarded wipe would be “more visible” on the store’s asphalt exterior compared to the store’s lighter interior floor, and Black said, “It would be more visible on the asphalt.” Counsel then asked, “why not just put the wipe station outside,” and Black testified, “It just doesn’t make sense.” When asked “[w]hy not,” Black replied, “That store faces south. The sun is hitting the front of that store. Majority of the day those wipes would come out completely dry in my opinion …. Other things could happen with it being placed outside. It could be vandalized. It could fall over. It could be a danger. It makes more sense with those things in mind to keep it inside.” Counsel asked whether it was “feasible to keep the wipes station outside” from a business perspective, and Black stated, “It makes no sense to me to have it outside.” Counsel concluded this line of 4 questioning by asking, “Has it ever been put outside,” and Black replied, “No, I don’t recall, to my knowledge.” At that point, Melendez’s counsel requested the court’s permission to display three photographs that his co-counsel had taken a few days earlier, which purportedly showed that Stater Brothers had moved the wet wipe stand outside and in front of the Alta Loma store at some point after Melendez’s accident. Melendez’s counsel sought to show the photographs to the jury to impeach Black; alternatively, counsel argued the photographs were admissible to prove it was feasible for Stater Brothers to move its wet wipe stand outside. Stater Brothers’s counsel opposed these requests, arguing the photographs did not impeach Black because he was not the manager of the Alta Loma store at the time the photographs were taken and he had merely expressed his opinion about the downsides of moving the wet wipe stand outside. Stater Brothers’s counsel also argued that evidence of a subsequent remedial measure is generally inadmissible in a negligence case, no foundation had been laid for the photographs, and it appeared to Stater Brothers’s counsel that her client had only moved the wet wipe stand outside because the store entryway was undergoing a remodel. The trial court “sustain[ed] the objection,” prohibited Melendez from using the photographs for impeachment, and excluded the photographs from evidence. The court found the photographs did not impeach Black, as he no longer worked at the store and had merely expressed an opinion that, “for [him], it’s unsafe” to place the wet wipe stand outside. The court also excluded the photographs from evidence. The court opined that the photographs were inadmissible because they were evidence of a subsequent 5 remedial measure, the photographs were irrelevant, and there was a “problem with [Evidence Code section] 352.”1 3. Limitation on Closing Arguments Near the end of trial, Stater Brothers orally moved for a partial directed verdict challenging Melendez’s new theory of liability “that the wipe stand needed to be moved outside,” and the court requested written briefing on the topic. In its brief, Stater Brothers argued a partial directed verdict was warranted because the complaint did not allege the location of the wet wipe stand was a dangerous condition, Melendez did not disclose in her discovery responses that she believed the location of the wet wipe stand was a dangerous condition, and there was no evidence from trial tending to show that the location of the wet wipe stand itself was a dangerous condition. The court construed the partial directed verdict motion as a motion in limine, granted the motion as construed, and prohibited Melendez from arguing to the jury that Stater Brothers should have moved the wet wipe stand. The court cited several justifications for its ruling, including the absence of evidence that the wet wipe stand should have been moved, the improper attorney arguments made during Melendez’s opening statements, the photographs Melendez had tried to display and/or admit into evidence, and the fact that Melendez’s discovery responses did not disclose that she intended to rely on the placement of the wet wipe stand as the basis for her claims. The court explained, “I think there should have been notice regarding this. Whether you use an expert or layperson, I think an expert could have talked about this. I don’t think it’s common sense regarding where those stands go …. I think it’s in the purview of an expert but you [could] also have 1 Further undesignated statutory references are to the Evidence Code.

6 a lay witness testify about it ….” The court later added, “It was not suggested previously that the stand was dangerous and needed to be moved …. [T]here were opportunities where it should have been talked about, it wasn’t talked about[,] and it still didn’t emerge in questioning the lay witness [Black].” 4. Jury Verdict and Judgment After closing statements and a few hours of deliberations, the jury quickly returned a verdict that Stater Brothers was not liable on either cause of action. On the special verdict form, the jury found that Stater Brothers owned, leased, or occupied the property on which the accident occurred. However, by a vote of 11–1, the jury found that Stater Brothers was not negligent in the use or maintenance of the property. The court entered judgment for Stater Brothers in accordance with the verdict, and Melendez filed a timely notice of appeal. III DISCUSSION A. The Trial Court Properly Exercised its Discretion by Excluding the Proffered Photographs of a Subsequent Remedial Measure Melendez contends the court abused its discretion by excluding the photographs showing that Stater Brothers had moved the disinfecting wet wipe stand to the outside of its Alta Loma store at some unknown point in time after her accident and before trial. She claims the court erred by excluding the photographs because she did not offer the photographs to prove that Stater Brothers was negligent; instead, she offered the photographs to prove it was feasible for Stater Brothers to move the stand outside. “We review a trial court’s decision to admit or exclude evidence under the abuse of discretion standard.” (Austin B. v. Escondido Union School Dist. (2007) 149 Cal.App.4th 860, 885.) “Under this standard, the trial court’s 7 ruling will not be disturbed, and reversal of the judgment is not required, unless the trial court exercised its discretion in an arbitrary, capricious, or patently absurd manner that resulted in a manifest miscarriage of justice.” (Bowser v. Ford Motor Co. (2022) 78 Cal.App.5th 587, 610.) Stated another way, a court abuses its discretion if its ruling “is ‘so irrational or arbitrary that no reasonable person could agree with it.’ ” (Sargon Enterprises, Inc. v. University of Southern California (2012) 55 Cal.4th 747, 773.) Section 1151 governs the admission of evidence of a defendant’s subsequent remedial measure in a negligence case. It states, “When, after the occurrence of an event, remedial or precautionary measures are taken, which, if taken previously, would have tended to make the event less likely to occur, evidence of such subsequent measures is inadmissible to prove negligence or culpable conduct in connection with the event.” (§ 1151.) “According to its draftsmen, section 1151 was intended merely to codify ‘well-settled law.’ [Citation.] The rule excluding evidence of subsequent repairs originally rested on the notion that such repairs were completely irrelevant to the issue of defendant’s negligence at the time of the accident.” (Ault v. International Harvester Co. (1974) 13 Cal.3d 113, 118–119 (Ault).) However, more recent judicial decisions “acknowledge that evidence of subsequent repairs is relevant to the issue of negligence, for if the changes occur closely in time they may well illustrate the feasibility of the improvement at the time of the accident, one of the normal elements in the negligence calculus.” (Id. at p. 119.) Even so, “courts and legislatures have frequently retained the exclusionary rule in negligence cases as a matter of ‘public policy,’ reasoning that the exclusion of such evidence may be necessary to avoid deterring individuals from making improvements or repairs after an accident has occurred.” (Ibid.; see Hilliard v. A.H. Robins 8 Co. (1983) 148 Cal.App.3d 374, 401 [“This statutory exclusion of evidence rule is based on a public policy consideration that the exclusion of such evidence encourages persons to take subsequent precaution for the purpose of promoting and encouraging safety, without fear of having such conduct used to establish liability.”].) “ ‘Section 1151 by its own terms excludes evidence of subsequent remedial or precautionary measures only when such evidence is offered to prove negligence or culpable conduct.’ ” (Alcaraz v. Vece (1997) 14 Cal.4th 1149, 1169, original italics.) Therefore, “[w]hile public policy precludes the court from considering [evidence of a subsequent remedial measure] after [an] accident on the issue of liability, such evidence is relevant and admissible … on the possibility or feasibility of eliminating the cause of the accident.” (Baldwin Contracting Co. v. Winston Steel Works, Inc. (1965) 236 Cal.App.2d 565, 573; see Dincau v. Tamayose (1982) 131 Cal.App.3d 780, 796 [“if the subsequent events are offered to prove anything other than negligence or culpable conduct, they are admissible if relevant”].) However, such evidence should only be admitted for this purpose “if a defendant declares that nothing could have been done to avoid the accident.” (People v. Lockheed Shipbuilding & Const. Co. (1975) 50 Cal.App.3d Supp. 15, 36; see McIntyre v. The Colonies-Pacific, LLC (2014) 228 Cal.App.4th 664, 673 [court properly excluded evidence that shopping center hired security after robbery where “the conditions at the shopping center when the jewelry store was robbed were undisputed,” and evidence “was unnecessary to show there was no security service prior to the robbery”]; Ault, supra, 13 Cal.3d at p. 127 (dis. opn. of Clark, J.) [disagreeing with majority’s holding that section 1151 does not apply to strict liability claims and reasoning that, if section 1151 applied, it would bar evidence of subsequent remedial measure 9 because “[f]easibility was not a contested issue”]; accord Gauthier v. AMF, Inc. (9th Cir. 1986) 788 F.2d 634, 637–638 [applying federal analogue to section 1151 and concluding court erred by admitting evidence of subsequent remedial measure because defendant “did not dispute feasibility”].) Melendez argues the court abused its discretion by excluding the photographs because Stater Brothers contested the feasibility of moving the wet wipe stand outside the store. However, the record does not support Melendez’s claim that Stater Brothers contested the issue of feasibility. Importantly, she does not refer us to any trial court briefing in which the company contested feasibility. Nor does she refer us to any oral arguments delivered by Stater Brothers’s counsel suggesting that the company disputed the feasibility of moving its wet wipe stand. Instead, Melendez rests her feasibility argument solely on the testimony of Black, the former Alta Loma store manager who briefly expressed his view that, “in [his] opinion … [i]t ma[de] no sense to [him] to have [the wet wipe stand] outside,” because he believed the disinfectant wet wipes could dry out if they were left outside, and the wet wipe stand could fall over or be vandalized. Based on this testimony alone, Melendez argues that the company disputed the issue of feasibility at trial. She repeatedly emphasizes that Stater Brothers previously designated Black as the “personal most qualified” to discuss the company’s safety procedures at a pretrial deposition, and she suggests that this deposition designation granted him the authority to represent the company’s litigation position at trial.2 2 For instance, Melendez argues, “Stater Bros insists that Mr. Black’s testimony was merely his personal opinion. It was not. Mr. Black delivered his testimony with the authority conferred on him by Stater Bros’ [sic] as its person most qualified to testify about safety policies and procedures.”

10 We are not persuaded. The term “person most qualified” is used in the Civil Discovery Act to describe an individual who should be designated and produced at deposition when the deponent is an entity and not a natural person. (LAOSD Asbestos Cases (2023) 87 Cal.App.5th 939, 947–948.) However, for purposes of trial, “[t]he Evidence Code recognizes only two types of witnesses: lay witnesses and expert witnesses.” (Id. at p. 947.) “There is no special category of ‘corporate representative’ witness,” nor is there “a special category of ‘person previously designated as most knowledgeable’ witness.” (Ibid.) In the present case, Black, the former manager of the Alta Loma store, testified as a lay witness at trial. And, as a lay witness, he expressed his “opinion” that “[i]t ma[de] no sense to [him] to have [the stand] outside.” This brief testimony from Black, a lay witness, was insufficient to demonstrate that Stater Brothers contested the issue of feasibility at trial. Because Melendez has not shown that Stater Brothers contested the feasibility of moving its wet wipe stand outside its store, the trial court properly exercised its discretion when it excluded the photographs of the company’s alleged subsequent remedial measure.3 B. The Trial Court Did Not Abuse its Discretion by Limiting the Scope of Melendez’s Closing Argument Next, Melendez contends the court abused its discretion by precluding her trial counsel from arguing to the jury during closing arguments that 3 Given our conclusion that the trial court properly excluded the photographs under section 1151, it is unnecessary for us to decide whether Melendez forfeited her challenge to the evidentiary ruling by failing to address the trial court’s alternative findings that the evidence was irrelevant (§ 210) and subject to exclusion because its probative value was substantially outweighed by countervailing considerations (§ 352). (David v. Medtronic, Inc. (2015) 237 Cal.App.4th 734, 740 [a party’s failure to challenge a “second, independent ground” underpinning an order on review constitutes waiver].)

11 Stater Brothers should have moved the location of its disinfectant wet wipe stand. She asserts the court erred in curtailing her counsel’s closing arguments because Stater Brothers had notice of her theory of liability and there was evidence that Stater Brothers could have mitigated the risk of injury by moving its wet wipe stand. We discern no abuse of discretion. “A trial court ‘is given great latitude in controlling the duration and limiting the scope of closing’ argument. [Citation.] It ‘may ensure that argument does not stray unduly from the mark, or otherwise impede the fair and orderly conduct of the trial.’ ” (People v. Edwards (2013) 57 Cal.4th 658, 743; see also Code Civ. Proc., § 128, subd. (a)(3) [“Every court shall have the power to … [¶] (3) To provide for the orderly conduct of proceedings before it, or its officers.”]; Wegner et al., Cal. Practice Guide: Civil Trials & Evidence (The Rutter Group 2025) ¶ 13:31 [“Trial courts have great latitude in controlling the duration and limiting the scope of closing argument.”].) The trial court precluded Melendez’s counsel from arguing to the jury that Stater Brothers should have moved the location of its wet wipe stand primarily because Melendez did not provide Stater Brothers with notice that she believed the location of the wet wipe stand itself constituted a dangerous condition. The record supports the court’s ruling on this point. In Melendez’s complaint, she alleged Stater Brothers breached its duty of care by “failing to inspect and properly remove disposal paper towels and spilled water which had been littered around the floor near a temporary sanitation station.” The complaint further alleged the condition “existed for sufficient time to have been discovered by [Stater Brothers] in the exercise of due care, and would have been discovered by a reasonably adequate inspection system maintained and operated with due care.” However, the complaint did not allege that the location of the wet wipe stand itself constituted a dangerous condition, nor 12 did the complaint allege that Stater Brothers breached its duty of care by placing the wet wipe stand in the entryway of its store, or by failing to move the stand to another area of the store. Further, Melendez never sought leave of court to amend her complaint to allege this new theory of liability. Melendez also did not disclose her theory of liability concerning Stater Brothers’s allegedly negligent placement of its wet wipe stand in discovery. Pertinent here, Stater Brothers propounded a contention interrogatory on Melendez asking her to identify the facts upon which she based her claims for damages, and she replied, in relevant part, “Plaintiff saw sanitation sheets on the ground near where she slipped. Plaintiff is informed and believes that defendant knew or should have known [about] this dangerous condition prior to the incident but failed to clean it in a timely manner and/or created this dangerous condition.” As this response illustrates, Melendez’s litigation stance up until trial was that Stater Brothers breached its duty of care by failing to clean the area surrounding its wet wipe stand and/or by discarding the wet wipe on which she slipped and fell. At no point prior to her opening statement did she disclose her new theory that Stater Brothers breached its duty of care by placing its wet wipe stand in the entryway of its store. In analogous procedural contexts, courts have cautioned against allowing parties to present new legal theories at trial, which has been described as “trial by ambush.” (Deyo v. Kilbourne (1978) 84 Cal.App.3d 771, 781.) As one court explained, “[s]urprise at trial is unfair because ambushes, while effective in warfare, are disfavored in court.” (McDonald v. Zargaryan (2025) 117 Cal.App.5th 344, 349.) It is also “inefficient because, if both sides know exactly what evidence the trial will produce, they have a better chance of agreeing in advance on the true value of the case. This promotes settlement. Cards up the sleeve make settlement less likely.” (Ibid.; see 13 Duchrow v. Forrest (2013) 215 Cal.App.4th 1359, 1377–1383 [court abused its discretion by allowing party to amend complaint mid-trial to assert new liability theory in breach of contract action]; Williams v. Volkswagenwerk Aktiengesellschaft (1986) 180 Cal.App.3d 1244, 1254–1255 [“As the California Supreme Court stated in explaining the purpose of the [California Discovery Act of 1957]: ‘[T]he Legislature intended to take the “game” element out of trial preparation while yet retaining the adversary nature of the trial itself. One of the principal purposes of discovery was to do away “with the sporting theory of litigation—namely, surprise at trial.” ’ ”].) Because Melendez failed to disclose her theory of liability prior to trial, the court properly excluded argument on that theory. While imposing limits on Melendez’s closing argument, the trial court also observed that there was no evidence from trial suggesting that Stater Brothers should have moved its wet wipe stand to another location. We agree with the court. Black testified at trial that Stater Brothers should eliminate potential safety hazards and mitigate risks, items on the floor of the store are dangerous, and discarded wipes are more visible on asphalt. However, neither Black nor any other witness testified that the wet wipe stand should be moved. On the contrary, Black testified that, in his view, it made no sense to move the stand outside for several reasons, including the risks of the wipes drying out, the stand being vandalized, and the stand being knocked over. “ ‘ “[W]hile a counsel in summing up may indulge in all fair arguments in favor of his client’s case, he may not assume facts not in evidence or invite the jury to speculate as to unsupported inferences.” ’ ” (Sacramento Area Flood Control Agency v. Dhaliwal (2015) 236 Cal.App.4th 1315, 1338.) Given the paucity of evidence that Stater Brothers should have moved its wet wipe stand to another location, as well as Melendez’s failure to 14 provide Stater Brothers with notice about her theory or liability before trial, the court properly exercised its discretion in disallowing closing argument on whether the location of the wet wipe stand was a dangerous condition and whether the company should have moved its wet wipe stand elsewhere.4 Even if the court had erred by limiting the scope of Melendez’s closing arguments, we would nonetheless affirm the judgment because she has not established that the claimed error was prejudicial. “ ‘In civil cases, a miscarriage of justice should be declared only when ... it is reasonably probable that a result more favorable to the appealing party would have been reached in the absence of the error.’ [Citation.] Prejudice from error is never 4 In her opening appellate brief, Melendez presents two related arguments that find no support in the appellate record. First, Melendez argues the trial court erroneously “ruled that an expert witness must testify that the wipe stand should have been moved.” The court did not make such a ruling. As discussed above, the court ruled that Melendez could not present closing arguments on her new theory of liability because it lacked evidentiary support and she did not disclose the theory to Stater Brothers before trial. While making this ruling, the court opined that expert testimony likely would have been required to prove the point, but “[w]hether [Melendez] use[d] an expert or layperson,” she could not discuss the issue in closing because she gave no notice to Stater Brothers about her theory and “it wasn’t talked about” by any witness. Second, Melendez contends the court erred by concluding that Stater Brothers’s contention interrogatory required her to disclose all witnesses, documents, and evidence on which she intended to rely at trial. Once more, the record does not support Melendez’s claim. The court did not rule that the company’s interrogatory required her to identify all evidence on which she intended to rely at trial. Instead, it ruled that her counsel could not present her new theory of liability in closing and emphasized, in particular, that she had not articulated her theory of liability in response to Stater Brothers’s interrogatory. As discussed, that interrogatory asked Melendez to articulate all facts (not all evidence) supporting her claim for damages.

15 presumed but must be affirmatively demonstrated by the appellant.” (Paige v. Safeway, Inc. (2022) 74 Cal.App.5th 1108, 1127.) Assuming error, we conclude it is not reasonably probable that the jury would have returned a more favorable verdict for Melendez but-for the court’s ruling. During closing arguments, Melendez’s counsel continually referred to the risks posed by the location of the wet wipe stand and suggested the stand should be moved, notwithstanding the trial court’s ruling. Indeed, at the outset of his closing argument, Melendez’s counsel asserted, “This wipe station that’s at the front of the store, at the entrance …. [T]his station, where it was situated, [was] in an unsafe condition.” Shortly after, he added, “[T]hat wipe station, where it was located created an unreasonable risk of harm.” Counsel later argued, “So we talked about eliminat[ing], repairing the condition. … But they chose to keep it there. And so since they chose to leave it there and not repair the condition, they needed to mitigate it.” During rebuttal, Melendez’s counsel again portrayed the location of the wipe stand as the dangerous condition underpinning her causes of action, arguing, “[W]here you have a known safety hazard, you have to take reasonable steps to get rid of it. What did they do? They knew that this wipe station was here. They had known about it for years. … They knew this was a high-traffic area. They knew that this was a problem.” Thereafter, he asserted, “[T]here was a lot they could have done. There [were] a lot of options we discussed. This location was unsafe. But if they chose to leave it there, there’s other options that they could have considered. What did they consider? Nothing.” Notwithstanding these repeated references to the location of the wet wipe stand, as well as the suggestions that Stater Brothers should have moved the stand elsewhere, the jury deliberated for just a few hours before 16 returning a swift and decisive finding (by a vote of 11–1) that Stater Brothers was not negligent. On this record, Melendez has not established a reasonable probability that the jury would have returned a verdict more favorable to her if the court had not limited the scope of her closing arguments.5 IV DISPOSITION The judgment is affirmed. Respondent is awarded its appellate costs.

5 In her reply brief, Melendez contends her counsel’s arguments did not transgress the trial court’s in limine ruling because they were “based on jury instructions to which Stater Bros stipulated.” We are not persuaded. Although Stater Brothers stipulated to the pattern jury instructions setting forth the elements for Melendez’s claims, it did not agree to allow Melendez’s counsel to argue to the jury that the location of the wet wipe stand constituted a dangerous condition that could have been eliminated or mitigated if Stater Brothers had moved the stand.
