UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA
) LAKEY L. DAVENPORT, ) ) Plaintiff, ) ) v. ) Civil Action No. 20-cv-1207 (TSC) ) SAFEWAY, INC., ) ) Defendant. ) )
MEMORANDUM OPINION
Plaintiff Lakey L. Davenport was working for a third-party vendor at a Safeway store in
Washington, D.C., when she slipped on a rogue shrimp and fell, sustaining personal injuries.
She sued Safeway, alleging that the store was negligent in failing to properly inspect and
maintain the floor and/or warn her of any unsafe conditions, and that the store’s negligence
caused her fall and resulting injuries. Safeway moves for summary judgment and moves in
limine to exclude Davenport’s expert witness, Michael D. Leshner, from testifying at trial.
For reasons explained below, the court will DENY Safeway’s Motion for Summary
Judgment, ECF No. 20, and GRANT Safeway’s Motion in Limine, ECF No. 21.
I. BACKGROUND
On February 14, 2018, Davenport was working for a third-party vendor, KeHe
Distributors, LLC, stocking shelves at a Safeway store located at 1855 Wisconsin Avenue, NW,
Washington, D.C. Def. Mot. Summ. J. (“Def. MSJ”), Ex. A, Davenport Dep. Tr. at 22:22–23:8,
26:22. She was responsible for bringing boxes of items from the store’s basement and stocking
those items on the store’s shelves. Id. at 23:20–28:4. Safeway maintained a “floor care program,” pursuant to which employees were
instructed to sweep the store’s floors once at the top of the hour and inspect or sweep the floors
at the bottom of the hour. Def. MSJ, Ex. B, Walden Dep. Tr. at 18:5–19; ECF 25–2, Pl.
Statement of Disputed Facts (“Pl. SDF”) ¶¶ 10–11. According to James Walden, Safeway’s
Director of Food Safety and Occupational Safety, the store also maintained an “educational
information plan,” and distributed a monthly safety “advertisement” to employees. Id. at 25:3–9.
Walden testified that at least once per year, the safety advertisement’s focus is preventing slip
and falls by instructing employees to address hazards as they see them. Id. at 25:9–14; see also
ECF No. 25–3, Ex. 2, Leshner Rep. at 11.
The store maintained a “Sweep Log,” recording when the floors were swept and by
whom. Def. MSJ at 8; Walden Dep. Tr. at 26:15–21; Pl. SDF ¶ 11; Leshner Rep. at 10. The
store’s Sweep Log shows that on the day Davenport fell, employees swept roughly every 30
minutes, and that employee Andre Council swept at 12:31 p.m., 1:09 p.m., and 1:34 p.m.
Leshner Rep. at 10. The record does not indicate the specific aisles or walkways that Council
swept. See id.
Safeway claims that “hourly floor sweeps were completed at the store up to the time
[Davenport] slipped and fell.” Def. MSJ at 5. Davenport, however, disputes two aspects of that
assertion. First, she argues that video surveillance shows that during the 1:34 p.m. sweep,
Council did not sweep the area in front of the freezer case where Davenport later slipped and fell.
Pl. SDF ¶ 11 (citing Leshner Rep. at 4). Second, she contends that after the 1:34 p.m. sweep,
Safeway employees did not conduct another floor inspection or sweep at the top of the hour, as
required by the “floor care program,” and did not conduct another inspection or sweep until 4:30
p.m. Id.; Leshner Rep. at 9–10.
Page 2 of 14 At approximately 2:22 p.m., Davenport walked by a freezer case near the store’s fresh
seafood counter. Def. MSJ at 2; Davenport Dep. Tr. at 28:5–8; ECF No. 25, Pl. Opp’n to Mot.
Summ. J (“Pl. Opp’n to MSJ”) at 3. She was not looking down and did not notice that a lone,
raw shrimp lay in her path. Davenport Dep. Tr. at 38:11–39:9. She slipped, fell, and allegedly
injured her right wrist, neck, and back. ECF No. 6, Compl. ¶ 9. But see Davenport Dep. Tr. at
59:2–16 (testifying that she sustained injuries to her left hand and left knee and did not suffer any
other injuries). After her fall, Davenport noticed one or two drops of water on the floor, along
with a “smushed shrimp” she blames for her slip. Id. at 31:22–32:4. She testified that she
believes the shrimp likely came from the fresh seafood counter located near the scene of the
accident, see id. at 52:1–53:19, but the parties have no explanation for when or how the shrimp
escaped the confines of the seafood section and arrived on the floor. Def. MSJ at 5; Pl. SDF ¶
10.
Davenport designated Michael Leshner, a professional engineer, to provide expert
testimony regarding the accident and Safeway’s liability. Leshner is a mechanical engineer with
self-reported expertise in “forensic engineering, safety engineering, consumer products, and
industrial products.” Leshner Rep. at 1. Leshner viewed video surveillance of the accident and
“the file”—presumably documents produced during discovery—and prepared a Preliminary
Report in which he opined:
Based on the materials I have reviewed, the incident occurred as reported. Ms. Davenport slipped because a slippery foreign object remained on the floor, was not swept up, and she did not see it before slipping and falling.
Safeway has a policy of sweeping the entire lobby, grocery area, produce area and restrooms at least once every 30 minutes. The incident area was swept at 1:31 as shown in photos 3, 4, and 5. That area was not swept again for another three hours, during which time this incident occurred. Such policies are required to maintain compliance with industry standards such as the Property Maintenance Code and other DC regulations.
Page 3 of 14 If Safeway had complied with industry codes, standards and regulations in addition to their own internal safety policies, the floors would have been kept free of foreign objects and carts would not be placed as shown in photo 5, making it difficult to observe the floor and keep it clean. This incident and resulting injuries occurred because the property was not maintained adequately.
Id. at 13-14. Leshner then reached the following four conclusions:
1. The incident was caused by Safeway’s failure to properly maintain safe walking surfaces;
2. Safeway violated industry standards, including the DC Property Maintenance Code;
3. Davenport did not cause or contribute to the incident; and
4. Had Safeway complied with industry and internal safety procedures, the incident would not have occurred.
See id. at 1, 14.
In his report, Leshner contends that in reaching these conclusions, he applied methods
that are “generally accepted in the community of Professional Engineers;” methods which he
“routinely appl[ies] in the practice of professional engineering.” Id. at 1.
During his deposition, when pressed on the basis for his opinion that Davenport slipped
on a foreign object, Leshner testified that he “understand[s] the mechanics of human
locomotion” and “how people walk,” and that when he reviewed the video footage of
Davenport’s fall, he observed Davenport’s lead foot slide out ahead of her. Pl. Opp’n to MSJ,
Ex. 2, Leshner Dep. Tr. at 14:5–17, 15:4. He also testified that he did not rely on any
engineering book or topic in reaching that opinion, and was “not sure” whether his opinion
“draws upon [his] forensic engineering experience or [his] mechanical engineering experience.”
Id. at 15:3, 15:14–21.
Page 4 of 14 Safeway moves for summary judgment and moves in limine to exclude Leshner from
testifying at trial.
II. LEGAL STANDARD
A. Motion for Summary Judgment
Summary judgment may be granted if “the movant shows that there is no genuine dispute
as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P.
56(a); see also Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247–48 (1986) (“[T]he mere
existence of some alleged factual dispute between the parties will not defeat an otherwise
properly supported motion for summary judgment; the requirement is that there be no genuine
issue of material fact.”) (emphasis in original); Holcomb v. Powell, 433 F.3d 889, 895 (D.C. Cir.
2006). Summary judgment may be rendered on a “claim or defense . . . or [a] part of each claim
or defense.” Fed. R. Civ. P. 56(a).
“A party asserting that a fact cannot be or is genuinely disputed must support the
assertion by . . . citing to particular parts of materials in the record.” Fed. R. Civ. P. 56(c)(1)(A).
“A fact is ‘material’ if a dispute over it might affect the outcome of a suit under governing law;
factual disputes that are ‘irrelevant or unnecessary’ do not affect the summary judgment
determination. An issue is ‘genuine’ if ‘the evidence is such that a reasonable jury could return a
verdict for the nonmoving party.’” Holcomb, 433 F.3d at 895 (quoting Liberty Lobby, 477 U.S.
at 248) (citation omitted). The party seeking summary judgment “bears the heavy burden of
establishing that the merits of his case are so clear that expedited action is justified.” Taxpayers
Watchdog, Inc. v. Stanley, 819 F.2d 294, 297 (D.C. Cir. 1987).
In considering a motion for summary judgment, “[t]he evidence of the non-movant is to
be believed, and all justifiable inferences are to be drawn in his favor.” Liberty Lobby, 477 U.S.
Page 5 of 14 at 255; see also Mastro v. Potomac Elec. Power Co., 447 F.3d 843, 850 (D.C. Cir. 2006) (“We
view the evidence in the light most favorable to the nonmoving party and draw all inferences in
its favor.”). The nonmoving party’s opposition, however, must consist of more than mere
unsupported allegations or denials, and must be supported by affidavits, declarations, or other
competent evidence setting forth specific facts showing that there is a genuine issue for trial. See
Fed. R. Civ. P. 56(c); Celotex Corp. v. Catrett, 477 U.S. 317, 324 (1986). The non-movant is
“required to provide evidence that would permit a reasonable jury to find [in his favor].”
Laningham v. U.S. Navy, 813 F.2d 1236, 1242 (D.C. Cir. 1987).
B. Admissibility of Expert Testimony
A district court has “great discretion” in determining whether to admit or exclude expert
testimony. United States v. Morgan, 45 F.4th 192, 200 (D.C. Cir. 2022). Under Federal Rule of
Evidence 702, which governs the admissibility of expert testimony, a “witness who is qualified
as an expert by knowledge, skill, experience, training, or education may testify . . . if: (a) the
expert’s scientific, technical, or other specialized knowledge will help the trier of fact to
understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient
facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the
expert has reliably applied the principles and methods to the facts of the case.” Fed. R. Evid.
702. Under Rule 702, “trial courts are required to act as gatekeepers who may only admit expert
testimony if it is both relevant and reliable.” Heller v. District of Columbia, 952 F. Supp. 2d
133, 139 (D.D.C. 2013) (citing Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 589
(1993); Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 141 (1999) (applying Daubert’s
holding to non-scientific expert testimony)).
Page 6 of 14 III. ANALYSIS
A. Motion for Summary Judgement
In a negligence action brought under District of Columbia law, such as this one, the
plaintiff “has the burden of establishing the applicable standard of care, a deviation from that
standard by the defendant, and a causal relationship between the deviation and the plaintiff’s
injury.” Young v. District of Columbia, 752 A.2d 138, 145 (D.C. 2000) (internal quotation marks
omitted); see also Martin v. Omni Hotels Mgmt. Corp., 206 F. Supp. 3d 115, 121 (D.D.C. 2016).
“It is established law in this jurisdiction that a storekeeper is not an insurer or guarantor of his
customers’ safety . . . [and] the mere happening of an accident does not impose liability or permit
an inference of negligence.” Napier v. Safeway Stores, Inc., 215 A.2d 479, 480 (D.C. 1965).
Rather, “[t]he burden rests upon the customer to prove the proprietor was negligent in either
creating the alleged condition or in permitting it to continue and that this negligence was the
proximate cause of the injuries.” Id. And “[i]t is axiomatic that under a negligence regime, one
has a duty to guard against only foreseeable risks.” Novak v. Cap. Mgmt. & Dev. Corp., 452
F.3d 902, 911–12 (D.C. Cir. 2006) (internal quotation marks omitted).
In the context of slip and fall premises liability cases, a plaintiff must establish either
actual or constructive notice of the dangerous condition. See Hudson v. Harris Teeter, LLC, 292
F. Supp. 3d 496, 499 (D.D.C. 2018). Constructive notice exists where the dangerous condition
existed for a long enough period that the owner of the premises should have been aware of it.
See id. (noting that where a negligence claim is “predicated upon the existence of a dangerous
condition it is necessary to show that the party against whom negligence is claimed had actual
notice of the dangerous condition or that the condition had existed for such length of time that, in
the exercise of reasonable care, its existence should have become known and corrected”); see
Page 7 of 14 also Sullivan v. AboveNet Commc’ns, Inc., 112 A.3d 347, 356 (D.C. 2015). In other words,
absent evidence of actual notice, “it is incumbent upon the injured customer to establish a factual
predicate sufficient to support a finding that the condition existed for such length of time that it
should have become known and have been corrected.” Hudson, 292 F. Supp. 3d at 499.
The parties dispute whether Safeway had constructive notice of the crustaceous hazard.
Safeway argues that there is no evidence about when or how the shrimp arrived on the floor, or
that any Safeway employee knew it was there. Safeway argues that, absent that evidence,
Davenport cannot establish that Safeway breached a duty of care.
Davenport contends that had Safeway adhered to its “floor care program,” and properly
swept and/or inspected the area in front of the freezer case at 1:34 p.m. and again at the top of the
hour, it might have discovered the errant shrimp and been able to mitigate the risk. In other
words, “had Safeway actually swept the floor before the accident, instead of completely ignoring
the area . . . the jury could definitively determine that the shrimp was not on the floor at” those
times. Pl. Opp’n to MSJ at 12.
Notice is a question ordinarily left for the jury. Hudson v. Harris Teeter, LLC, 292 F.
Supp. 3d 496, 499 (D.D.C. 2018). To be sure, “where there is no testimony about how a
substance came to be on the floor or how long it had been there, or that any employee of [the
defendant] knew of its existence, the court may properly decide the case as a matter of law
because of [the] failure to present prima facie proof of liability.” Id. at 499 (emphasis added)
(internal quotation marks omitted). Here, however, the evidence suggests that had Safeway
adhered to its own “floor care program,” “a trier of fact could have determined with some
assurance” the timing of the shrimp’s arrival on the floor. See WMATA v. Jeanty, 718 A.2d 172,
178 (D.C. 1998). Safeway, having allegedly failed to sweep or inspect the freezer-case area at
Page 8 of 14 1:34 p.m. and again at the top of the hour, “cannot now claim victory upon the ground that the
plaintiff was unable to establish facts which the missed inspections might well have revealed.”
Id. Because there is a genuine dispute as to the material fact of constructive notice, summary
judgment is inappropriate.
Safeway also argues that summary judgment is warranted because Davenport has failed
to identify a standard of care. That argument fails for three reasons.
First, Davenport argues that Safeway breached the standard of care set forth in the
International Maintenance Property Code, which requires that a “safe, continuous, and
unobstructed path of travel shall be provided from any point in a building or structure to the
Public Way.” Pl. Opp’n at 9 (citing International Property Maintenance Code § 702.1); see also
Girdler v. United States, 923 F. Supp. 2d 168, 189 (D.D.C. 2013) (“The D.C. Property
Maintenance Code, in turn, consists of the . . . International Property Maintenance Code.”).
Second, while “company rules are not ‘conclusive’ or ‘wholly definitive’” of the standard
of care, WMATA v. Young, 731 A.2d 389, 398 (D.C. 1999), such policies are “admissible as
bearing on the standard of care,” Briggs v. WMATA, 481 F.3d 839, 848 (D.C. Cir. 2007)
(emphasis in original) (quoting Clark v. D.C., 708 A.2d 632, 636 (D.C. 1997)). In other words,
evidence regarding Safeway’s compliance or failure to comply with its “floor care program”—a
disputed matter—is admissible and bears on whether it exercised due care in this case. See
Garrison v. D.C. Transit System, Inc., 196 A.2d 924, 925 (D.C. 1964) (“[R]egulations of a
defendant for guidance of its employees in the performance of their duties are admissible and
may be considered on the issue of whether due care was exercised by the employee under the
particular circumstances of the case.”).
Page 9 of 14 And third, in a “typical negligence case, the standard of care applicable to a person’s
conduct is simply that of a reasonable [person] under like circumstances[,]” and a jury can
ordinarily “ascertain this standard without the aid of expert testimony.” Godfrey v. Iverson, 559
F.3d 569, 572 (D.C. Cir. 2009) (internal citation quotation marks omitted). Accordingly, issues
of negligence are rarely appropriate for summary judgment. Stehn v. Cody, 962 F. Supp. 2d 175,
179 (D.D.C. 2013). As courts in the District of Columbia have repeatedly noted, “[o]nly in
exceptional cases will questions of negligence [and] contributory negligence . . . pass from the
realm of fact to one of law.” Paraskevaides v. Four Seasons Wash., 292 F.3d 886, 893 (D.C.
Cir. 2002) (quoting Shu v. Basinger, 57 A.2d 295, 295–96 (D.C. 1948)). This is not the type of
“exceptional” case that presents negligence questions for the court to decide as a matter of law.
Ultimately, because there are genuine disputes as to material facts bearing on Safeway’s
liability, the court will deny Safeway’s motion for summary judgment.
B. Motion to Exclude Expert Testimony
Safeway argues that Leshner’s proposed expert testimony must be excluded under Rule
702. See ECF No. 21, Def. Mot. in Limine. First, Safeway contends that Leshner’s opinion that
Davenport slipped on a foreign object requires no specialized education or training and therefore
is impermissible as expert opinion. Id. at 2–4. Second, Safeway argues that Leshner should not
be permitted to testify that Safeway caused the accident by failing to maintain safe walking
areas, or that Davenport did not contribute to the incident herself, because that testimony
amounts to inappropriate legal conclusions and relies on speculation. Id. at 5–7. And third,
Safeway argues that Leshner’s opinion that Safeway failed to comply with industry and internal
safety procedures is unfounded and irrelevant. Id. at 7–9.
Page 10 of 14 In Richter v. Virginia CVS Pharmacy, LLC, No. 1:21-CV-00394 (E.D. Va. Nov. 19,
2021), the plaintiff sued CVS for negligence after an anti-theft device—a long pole attached to
each shopping cart to prevent the shopping carts from being removed from the store—collided
with the top of a door frame, allegedly causing plaintiff to fall and sustain injuries. Richter, 2021
WL 6334671, at *1. The plaintiff retained Leshner as an expert witness, and he prepared a
preliminary report in which he concluded, in part, that: (1) the incident was caused by a
hazardous condition at the CVS store, i.e., the pole attached to the plaintiff’s shopping cart; (2)
the hazard caused the plaintiff to fall and become injured; (3) CVS violated industry standards,
including the Virginia Property Maintenance Code; and (4) if CVS had complied with industry
and internal safety procedures, this incident would not have occurred. Richter, 2021 WL
6125776, at *1. And, like this case, Leshner testified at his deposition that his “analysis is based
on a detailed review of the video and screenshots from the video,” and further states that the
tools used were “my eyes and my brain and my training . . . No formulas or calculations were
required.” Id. The court granted the defendant’s motion to exclude Leshner’s testimony at trial,
finding that Leshner did not apply scientific, technical, or specialized knowledge or methodology
to arrive at his opinions, and that his opinions constitute inadmissible legal conclusions.
The same outcome is warranted here. Leshner does not state, either in his expert report
or deposition testimony, how his experience or training informs his testimony. He stated that he
understands “human locomotion,” “how people walk” and “what causes them to fall,” but
conceded that he “can’t point to a specific book or topic” that informs his understandings.
Leshner Dep. Tr. at 14:6, 15:1–6. Moreover, the scientific methods that purportedly undergird
his conclusions amount simply to “review[ing] the [security] video frame by frame.” Id. at 32:2-
13. A juror is equally qualified to review the same video frame by frame to make their own
Page 11 of 14 factual findings. Leshner’s testimony would not “help the trier of fact to understand the evidence
or to determine a fact in issue” as required by Federal Rule of Evidence 702(a).
Leshner’s testimony that Safeway violated industry standards, including the DC Property
Maintenance Code, and that Safeway’s compliance would have avoided the incident, are also
impermissible. Leshner again fails to explain how his training or experience as an engineer
informs those conclusions. The tenuous relationship between his experience and opinions was
borne out at his deposition. He testified that he “didn’t read Safeway’s policies,” id. at 49:12,
and when asked whether he was “aware of any industry standards that dictate how often a store
like Safeway should sweep its floors,” he testified that he “couldn’t point . . . to any specific
policy,” and was only aware of regulations that more generally require a store to “maintain a safe
premises,” id. at 51:13–21. Leshner confirmed that those regulations “don’t tell [a store] how
often to sweep.” Id. at 52:4–5. He also conceded that one regulation cited in his report—
ASTM-F 1637-13—is a “voluntary standard,” that has not been adopted by the D.C. building or
maintenance code, id. at 56:17–57:11, nor has another regulation he cites—NFPA 101—been
adopted in D.C., id. at 57:12–14.
In short, Leshner’s proposed expert testimony does not satisfy Rule 702’s reliability
requirement that expert testimony be “properly grounded, well-reasoned, and not speculative.”
Fed. R. Evid. 702 advisory committee’s note. Although Leshner is an experienced engineer,
“‘the unremarkable observation that an expert may be qualified by experience does not mean that
experience, standing alone, is a sufficient foundation rendering reliable any conceivable opinion
the expert may express. . . . Quite simply, under Rule 702, the reliability criterion remains a
discrete, independent, and important requirement for admissibility.’” Heller, 952 F. Supp. 2d at
141 (quoting United States v. Frazier, 387 F.3d 1244, 1261 (11th Cir. 2004) (en banc) (emphasis
Page 12 of 14 in original)). Moreover, expert testimony about the standard of care is not required “if the
subject matter is within the realm of common knowledge and everyday experience.” Hill v.
Metro. Afr. Methodist Episcopal Church, 779 A.2d 906, 908 (D.C. 2001) (internal citation and
quotation marks omitted).
Leshner’s opinions are also impermissible because they amount to legal conclusions. His
testimony would be that Safeway caused Davenport’s fall by failing to adhere to industry
standards, and that Davenport did not contribute to the incident. Leshner Rep. at 14. In other
words, he seeks to testify about what result should be reached on the elements of negligence, and
thus his opinion testimony is improper. “Expert testimony that consists of legal conclusions
cannot properly assist the trier of fact in either understanding the evidence or determining a fact
in issue.” Burkhart v. Wash. Metro. Area Transit Auth., 112 F.3d 1207, 1212 (D.C. Cir. 1997)
(cleaned up). “This is because legal conclusions intrude upon the duties of, and effectively
substitute for the judgment of, the trier of fact and the responsibility of the Court to instruct the
trier of fact on the law.” Atlanta Channel, Inc. v. Solomon, No. CV 15-1823 (RC), 2020 WL
7013346, at *3 (D.D.C. Nov. 24, 2020) (cleaned up); see also Burkhart, 112 F.3d at 1212 (“[A]n
expert may offer [an] opinion as to facts that, if found, would support a conclusion that the legal
standard at issue was satisfied, but [the expert] may not testify as to whether the legal standard
has been satisfied.”); U.S. ex rel. Mossey v. Pal-Tech, Inc., 231 F. Supp. 2d 94, 98 (D.D.C. 2002)
(“[E]xpert testimony consisting of legal conclusions will not be permitted because such
testimony merely states what result should be reached.”).
Consequently, the court will grant Safeway’s Motion in Limine to exclude Leshner’s
proposed testimony.
Page 13 of 14 IV. CONCLUSION
For reasons set forth above, the court will DENY Safeway’s Motion for Summary
Judgment, ECF No. 20, and will GRANT Safeway’s Motion in Limine, ECF No. 21, to exclude
Leshner’s expert testimony.
