MEMORANDUM BY KING, J.: FILED APRIL 10, 2025
Appellant, Paige Taylor, appeals from the judgment entered in the
Philadelphia County Court of Common Pleas, in favor of Appellee, Just About
Me Learning Academy, LLC,1 in this negligence action. We affirm.
The relevant facts and procedural history of this appeal are as follows.
Appellant, an employee of the Commonwealth of Pennsylvania Department of
Human Services’ (“DHS”) Office of Child Development and Early Learning,
inspected the premises of Appellee Just About Me Learning Academy. Appellee
____________________________________________
1 Although “John Does 1-10” are listed in the caption, they were never served,
never entered an appearance, and no verdict was entered with respect to them. Thus, John Does 1-10 are not parties to the action. See Hill v. Ofalt, 85 A.3d 540, 546 n.5 (Pa.Super. 2014) (stating “everyone whose name appears in the caption of a praecipe for writ of summons is not necessarily a party to the action; parties to an action are those who are named as such in the record and are properly served with process or enter an appearance”) (quoting Liles v. Balmer, 653 A.2d 1237, 1239 n. 1 (Pa.Super. 1994)). J-A24021-24
requested that Appellant wear plastic shoe coverings to decrease the spread
of COVID-19. During the inspection, Appellant slipped and fell down a flight
of stairs.
On March 24, 2022, Appellant filed a complaint against Appellee for
negligence, claiming that Appellee failed to maintain the surface on which she
fell; failed to warn her about dangerous conditions; and provided unsafe shoe
covers. On June 23, 2023, the matter proceeded to compulsory, non-binding
arbitration, which found in favor of Appellee and against Appellant. That same
day, Appellant appealed the arbitration finding to the trial court.
On October 2, 2023, after the close of discovery, Appellee filed a motion
for summary judgment alleging that the condition of the staircase was not a
dangerous condition that would subject Appellee to liability; rather, Appellee
alleged that Appellant failed to step on the carpet runner partially covering
the step. In response, Appellant asserted that her foot had missed the partial
carpet strip due to the staircase tread being too narrow and the riser height
too high. Appellant submitted an expert report from a professional engineer
in support of this claim. The trial court denied Appellee’s motion for summary
judgment.
Subsequently, Appellee filed a motion in limine seeking to exclude
Appellant’s expert report, claiming that it offered a theory of liability that the
complaint did not include because the complaint did not allege that Appellee
constructed the stairs, and the complaint did not mention stair depth or height
and did not allege any violation of any building code or ordinance. In addition,
-2- J-A24021-24
Appellant filed a motion in limine to exclude Appellee’s expert report
concerning the shoe covering that Appellant was wearing at the time of the
fall. Appellant claimed that Appellee’s expert was not provided the exact shoe
coverings that Appellant wore, and the expert did not explain how she knew
that the shoe coverings that were provided were representative of the
coverings Appellee had provided to Appellant.
On January 12, 2024, the court denied Appellant’s motion in limine to
exclude Appellee’s expert report. On January 17, 2024, the trial court issued
an order ruling on Appellee’s motion in limine, limiting Appellant to presenting
evidence solely about the carpet stripping that Appellee had installed on the
stairs. The court excluded evidence related to codes, stair dimensions, and
creation of the stairs, explaining that the only party involved in the case is the
tenant of the building, not the landlord.
The matter proceeded to jury trial from January 17, 2024, through
January 23, 2024. Appellant presented the testimony on cross-examination
of Sharon Pannell, Appellee’s owner, and Verica Perkins, Appellee’s director;
the expert testimony of Dr. Randall Smith and Dr. James Barrese, both via
videotaped deposition; and the testimony of Paulette Taylor, Appellant’s
sister. Appellant testified on her own behalf. Appellee presented the expert
testimony of Dr. Joseph Bernstein, via videotaped deposition, and Dr. Vasiliki
Kefala, also via videotaped deposition. On January 23, 2024, the jury reached
a verdict in favor of Appellee and against Appellant.
On January 24, 2024, Appellant timely filed a post-trial motion, which
-3- J-A24021-24
the court denied on February 14, 2024. That same day, the court entered
judgment in favor of Appellee and against Appellant. On February 15, 2024,
Appellant timely filed a notice of appeal. On February 21, 2024, the court
ordered Appellant to file a Pa.R.A.P. 1925(b) statement of errors complained
of on appeal, and Appellant timely complied on February 29, 2024.
On appeal, Appellant presents the following issues for our review:
1. The trial court found that a tenant was not responsible for defects in a property that it leased. The trial court excluded direct evidence and expert opinion testimony about those defects, reasoning that a tenant is not responsible for dangerous conditions that it did not create. As an alternative ground for its decision, the trial court found that [Appellant’s] pleading did not allege a claim based on the defect even though the complaint alleged that the accident was caused by a “dangerous condition of the interior walking surface.” Were the exclusions of evidence error?
2. [Appellee’s] expert opined that shoe covers that [Appellee] provided to [Appellant] were not slippery enough to cause an accident yet did not know what shoe covers were provided and instead used “exemplars” of other shoe coverings. Did the expert lack an adequate basis for her opinion under Pa.R.E. 703?
(Appellant’s Brief at 4).
Our standard of review concerning a trial court’s ruling on a motion in
limine is well settled: “Admission of evidence is within the sound discretion of
the trial court and a trial court’s rulings on the admission of evidence will not
be overturned absent an abuse of discretion or misapplication of law.” Carlini
v. Glenn O. Hawbaker, Inc., 219 A.3d 629, 639 (Pa.Super. 2019) (citation
omitted). “To constitute reversible error, a ruling on evidence must be shown
-4- J-A24021-24
not only to have been erroneous but harmful to the party complaining.” Id.

not affect the verdict. Yacoub v. Lehigh Valley Medical Associates, P.C.,

805 A.2d 579, 590 (Pa.Super. 2002), appeal denied, 573 Pa. 692, 825 A.2d
639 (2003).
In her first issue, Appellant argues that the court improperly precluded
her proposed expert testimony regarding the physical dimensions of the
staircase and its noncompliance with the Philadelphia Code. Appellant asserts
that her complaint adequately raised physical defects in the surface on which
she slipped. Appellant contends that the trial court’s assertion that there was
a material variance between the complaint and evidence about the condition
of the staircase is incorrect. According to Appellant, there was no doubt she
had based her claim upon a dangerous condition of the staircase. Appellant
insists that she is not required to plead anything about the type of evidence
used to support her claim but must plead only the type of claim and
underlying events. Appellant submits that the trial court improperly excluded
evidence that was essential to her theory of liability. Appellant maintains that
it was the combination of dangers that Appellee permitted and created that
caused the injury, namely, the partially covered staircase, shoe covers, and
the dimensions of the staircase. Appellant suggests that the exclusion of her
evidence was not harmless and prejudiced her such that a new trial is
-5- J-A24021-24
required.2 We disagree.
Initially, we note that:
It is well settled that a variance between the pleadings contained in a plaintiff’s complaint and the theory the party later attempts to prove at trial may result in preclusion of the new theory if it constitutes a new cause of action and is prejudicial to the defense. Reynolds v. Thomas Jefferson University Hospital, [676 A.2d 1205, 1210 (Pa.Super. 1996)]. A proposed amendment of the complaint which adds or changes the theory of recovery upon which relief is sought through the introduction of new factual allegations generally constitutes a new cause of action. Id. at 1210- 11. “Stated differently, an amendment proposes a different theory or a different kind of negligence if the operative facts supporting the claim are changed.” Id. at 1211.
Rachlin v. Edmison, 813 A.2d 862, 871-72 (Pa.Super. 2002) (emphasis
added).
Further, challenges to the admission of expert testimony are reviewed,
as are other evidentiary challenges, on an abuse of discretion standard.
Farese v. Robinson, 222 A.3d 1173, 1185 (Pa.Super. 2019). Pennsylvania
Rule of Civil Procedure 1042.32 governs the admissibility of additional or
supplemental expert reports, stating:
2 Additionally, Appellant contends that that the trial court’s “apparent” initial
basis for its ruling—i.e., tenants are not responsible for dangerous conditions that already existed before their tenancy—is not correct. Rather, she claims that a tenant is the party responsible for a property’s condition during the lease’s term. However, the trial court’s opinion does not address this issue, and it is unclear to what portion of the record this argument refers. See Pa.R.A.P. 2119(c) (if reference is made to opinion or order or any other matter appearing in record, argument must include reference to place in record where matter referred to appears). Thus, we decline to address this argument.
-6- J-A24021-24
Until a deadline set by the court for the production of expert reports has passed or unless the court has precluded such production, a party may serve additional and supplemental expert reports without leave of court. These reports may introduce new theories of liability or causation or new defenses, and may be prepared by other experts.
Pa.R.C.P. 1042.32. Additionally, Pennsylvania Rule of Civil Procedure 4003.5
governs the discovery of expert testimony, stating:
An expert witness whose identity is not disclosed in compliance with subdivision (a)(1) of this rule shall not be permitted to testify on behalf of the defaulting party at the trial of the action. However, if the failure to disclose the identity of the witness is the result of extenuating circumstances beyond the control of the defaulting party, the court may grant a continuance or other appropriate relief.
Pa.R.C.P. 4003.5.
Pennsylvania Rule of Civil Procedure 4003.5 requires parties to timely submit their expert reports, and confines the expert’s testimony to the scope of those reports, to avoid unfair surprise. See Woodard v. Chatterjee, 827 A.2d 433, 445 (Pa.Super. 2003) (citing comment to Rule 4003.5(c) for proposition that the rule is intended “to prevent incomplete or ‘fudging’ of reports which would fail to reveal fully the facts and opinions of the expert or his grounds therefor”); see also Jones v. Constantino, [631 A.2d 1289, 1294 (Pa.Super.] 1993) (noting the fair scope rule “disfavors unfair and prejudicial surprise”). In such situations, trial courts may exclude the offending testimony entirely or, in some cases permit the opposing party to depose the witness during trial.

Instantly, the trial court explained:
Firstly, it should be noted that the trial court, when granting Appellee’s motion in limine, only precluded evidence as to codes, stair dimensions, and the actual creation of the stairs. In the instant matter, the trial court properly precluded Appellant’s expert witness, Jason Boyd, P.E., from testifying at trial because his testimony would have been supporting and advancing a new theory of negligence that was not contained in the complaint and such would have been prejudicial to Appellee. Appellant’s complaint states the following,
On or about October 14, 2020, [Appellant] was an invitee on the premises known as Just About Me Learning Academy, at 4802 N. Broad St., Philadelphia, Pennsylvania when she was given mandatory shoe covers to wear and was suddenly and unexpectedly caused to fall due to said shoe covers and a dangerous condition of the interior walking surface, thereby causing [Appellant] to sustain serious and permanent injuries which will hereinafter be more fully described.
The aforementioned incident was caused solely by the negligence of [Appellee] in failing to properly maintain the walkway in question, which negligence consisted of one of the following: a) failing to provide adequate and safe shoe covers for the particular walking surface on the premises; b) failing to properly inspect, discover, and remedy the defective conditions which existed on, of, and about the walkway, which [Appellee] knew or reasonably should have known existed prior to the time of [Appellant’s] accident; c) failing to warn members of the general public of the dangerous conditions which existed; d) allowing a dangerous and hazardous condition of the subject walkway to exist for an unreasonable amount of time; and/or e) creating the dangerous and hazardous walking condition of the subject walkway with said shoe covers.
-8- J-A24021-24
One of Appellant’s intended ways to prove the staircase was dangerous was Mr. Boyd’s expert testimony as to the unsafe staircase dimensions. Mr. Boyd would have testified at trial as an expert as to the staircase in relation to Philadelphia Fire Code 1101.5, which deals with stair riser height and stair tread depths, Philadelphia Property Maintenance Code 102.3, which states repairs, additions, or alterations to a structure shall be done in accordance with [various international building codes] as well as Philadelphia Property Maintenance Code 108.1.15, which details what is considered a dangerous structure due to the presence of certain conditions, Philadelphia Property Maintenance Code 305.4, which states that stairs and walking surfaces shall be maintained in sound condition and good repair, and ASTM F1637 5.2.4, which details a standard practice for safe walking surfaces. Mr. Boyd also conducted a site inspection of the staircase on September 28, 2023. Mr. Boyd’s expert report detailing such was issued on October 5, 2023, which was almost a year after the statute of limitations ran on Appellant’s negligence claim and after the applicable case management deadline.
Appellant’s complaint does not allege any facts regarding the staircase dimensions nor facts regarding Appellee violating any codes. Mr. Boyd’s expert testimony, if it were permitted, would have proposed a different theory/kind of negligence than the one previously raised in Appellant’s complaint. Thus, Mr. Boyd’s expert testimony would have been advancing a new cause of action inconsistent with the complaint’s facts. This introduction of a new cause of action, if it were permitted, would have greatly prejudiced Appellee because Appellee was never put on notice regarding the staircase dimensions and code/ordinance violations via the complaint nor during discovery. The staircase dimensions evidence does not correspond with the material facts pled in the complaint, and throughout discovery, Appellee was not provided a response to its interrogatories regarding any code violations and Appellant responded to Appellee’s discovery request concerning the cause of the accident, to which Appellant stated it was related to the shoe coverings, not anything related to the staircase dimensions. Furthermore, Mr. Boyd’s expert testimony, which was based on his report that was issued after the applicable deadlines and well after the statute of limitations ran on Appellant’s
-9- J-A24021-24
claim, advances a new cause of action that would have most certainly prejudiced Appellee at trial. The discrepancy in Mr. Boyd’s proposed expert testimony and what was alleged in Appellant’s complaint results in an inconsistency between the two, which allows preclusion of said evidence.
(Trial Court Opinion, 3/1/24, at 5-8) (some internal citations omitted).
We agree that the trial court’s analysis. The record confirms that
Appellant produced Mr. Boyd’s expert report on October 5, 2023, one month
after the applicable discovery deadline of September 5, 2023. The docket
entries indicate that Appellant never requested a continuance of the discovery
deadline or offered an explanation regarding the lateness of the report. See
Pa.R.C.P. 1042.32 (stating that until deadline set by court for production has
passed, party may serve additional expert reports). As the proffered expert
report advanced a new basis for relief not stated in the complaint, the trial
court properly excluded it to prevent unfair surprise to Appellee. See
Gregury, supra. See also Pa.R.C.P. 1042.32; Pa.R.C.P. 4003.5. Therefore,
Appellant is not entitled to relief on this issue. 3
In Appellant’s second issue, she argues that the trial court erred in
denying her motion in in limine seeking to exclude the expert testimony of Dr.
Vasiliki Kefala. According to Appellant, Dr. Kefala lacked an adequate basis
for her opinion in violation of Pa.R.E. 703. Specifically, Appellant contends
that Dr. Kefala opined that the shoe covers that Appellee provided were not
slippery enough to cause an accident. Appellant emphasizes that Dr. Kefala
3 Appellant’s brief does not provide further explanation as to why she failed to
meet the discovery deadline of September 5, 2023.
- 10 - J-A24021-24
did not know what specific shoe covers were provided and instead used
“exemplars” of other shoe coverings. Appellant concludes the trial court
should have granted her motion in limine to exclude this testimony, and this
Court must grant her a new trial. We disagree.
The Pennsylvania Rules of Evidence provide:
Rule 703. Bases of opinion testimony by experts
An expert may base an opinion on facts or data in the case that the expert has been made aware of or personally observed. If experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject, they need not be admissible for the opinion to be admitted.
Pa.R.E. 703. The Comment to the Rule further provides that:
When an expert testifies about the underlying facts and data that support the expert’s opinion and the evidence would be otherwise inadmissible, the trial judge upon request must, or on the judge’s own initiative may, instruct the jury to consider the facts and data only to explain the basis for the expert’s opinion, and not as substantive evidence.
Pa.R.E. 703, Comment.
Essentially,
[w]hile an expert’s opinion need not be based on absolute certainty, an opinion based on mere possibilities is not competent evidence. This means that expert testimony cannot be based solely upon conjecture or surmise. Rather, an expert’s assumptions must be based upon such facts as the jury would be warranted in finding from the evidence. Accordingly, the Pennsylvania Rules of Evidence prescribe a threshold for admission of expert testimony dependent upon the extent to which the expert’s opinion is based on facts and data.
Gillingham v. Consol Energy, Inc., 51 A.3d 841, 849 (Pa.Super. 2012)
- 11 - J-A24021-24
(citation omitted). Thus, an adequate basis in fact must enable the expert to
opine with a reasonable degree of certainty and is incompetent if it lacks an
adequate basis. See id.
In certain situations, it is not an abuse of discretion to allow expert
reports or testimony based on “exemplar” testing. See, e.g., Bourgeois v.
Snow Time, Inc., 663 Pa. 376, 388-90, 242 A.3d 637, 644-45 (2020)
(permitting expert report based on testing of five exemplar kitchen mats for
coefficient of friction testing). See also Sullivan v. Werner Company, 253
A.3d 730, 753-54 (Pa.Super. 2021) (explaining that probative value of video
showing testing of exemplar scaffold outweighed potential prejudice, where
manufacturer could attack exemplar through cross-examination). Compare
Nobles v. Staples, Inc., 150 A.3d 110, 116-117 (Pa.Super. 2016) (affirming
exclusion of expert report where expert did not inspect chair at issue and did
not apply any scientific expertise to conclude chair was defective, including
examining exemplar or any similar chair).
Instantly, the trial court observed:
Dr. Kefala’s expert testimony described how the walking surfaces where Appellant’s accident occurred on possessed sufficient friction for humans to walk on with shoe coverings. Dr. Kefala’s testimony was based on, a review of the complaint, Appellant’s testimony, Appellant’s medical records, photographs of the area where Appellant fell, and an inspection of Appellee’s premises, which included friction coefficient testing. Based on her experience in the fields of physics and biomechanical engineering, and market research, to perform the testing, Dr. Kefala selected five exemplar shoe coverings representative of the actual shoe coverings worn by Appellant on the date of her accident
- 12 - J-A24021-24
since the actual shoe coverings were never preserved. Dr. Kefala’s expert testimony did not lack an adequate basis in fact as Dr. Kefala’s expert opinion was based on facts made aware to her by way of the documents and testimony she reviewed along with facts stemming from the inspection and testing, which Dr. Kefala personally observed. Appellee’s counsel, in her response to Appellant’s motion in limine, cited to a Pennsylvania Supreme Court case, Bourgeois v. Snow Time, Inc.[, supra], in which the expert witness in that case used five exemplar kitchen mats during friction coefficient testing to make expert opinions regarding the actual kitchen mats used. The methodology in Bourgeois is similar if not identical to the instant matter. The fact that Dr. Kefala did not use the actual shoe coverings worn by Appellant on the day of the accident does not make Dr. Kefala’s expert opinion a product of speculation and/or conjecture. All of Dr. Kefala’s opinions were to a reasonable degree of scientific certainty. With Dr. Kefala’s expert opinion being based on facts/data she either reviewed herself or conducted herself it is not speculative, and her expert testimony was properly permitted at trial.
(Trial Court Opinion at 12-13) (citations to the record omitted).
The record supports the trial court’s conclusion. Dr. Kefala’s expert
report notes that she used five separate exemplar shoe covers, of a similar
style but “different brand and different kind,” to conduct coefficient of friction
testing and “ascertain their propensity to move on different types of surfaces”
at the subject location. (See N.T. Trial, 1/23/24, at 3, Def. Ex. 42). In her
deposition, which was played for the jury, Dr. Kefala testified that the shoe
covers were a “representative variety” of the shoe covers that “exist on the
market right now,” and that she had tested a variety of covers due to the fact
that there was no information available regarding the exact shoe cover
Appellant wore at the time she fell. (See N.T. Trial, 1/23/24, at 3, Def. Ex.
41, N.T. Deposition, 2/21/23, at 39-41). Dr. Kefala did not notice any “big
- 13 - J-A24021-24
differences” between the brands tested. (See id. at 41). Dr. Kefala described
at length her scientific testing process, which included multiple trials for each
brand of shoe cover at different locations on the premises, and she took the
average of each test to be more consistent. (See id. at 43-44). Thus, we
agree with the trial court that Dr. Kefala had an adequate basis for her report,
and we see no abuse of discretion by the trial court in permitting this
testimony, particularly where Appellant’s counsel was permitted to cross-
examine Dr. Kefala during her deposition. See Carlini, supra; Gillingham,
supra. See also Bourgeois, supra; Sullivan, supra. Accordingly,
Appellant is not entitled to relief on this claim, and we affirm.
Judgment affirmed.
