ORDER

Upon Defendant’s Motion in Limine – DENIED.

This 15th day of June, 2023, having considered Defendant’s Motion in 

Limine/Daubert Challenge, the Plaintiff’s Response, oral arguments of counsel and 

the record in this matter; it appears to the Court that:

1. Plaintiff Shawn Martin (hereinafter “Plaintiff”) filed suit alleging 

negligence against his employer, Defendant Nationwide Railroad Passenger 

Corporation, d/b/a Amtrak, (hereinafter “Defendant”) pursuant to the Federal 

Employers’ Liability Act (hereinafter “FELA”) alleging various claims of 

negligence, including the failure to provide its Police Officer employees tasers for 

carrying out their official duties. 
-2-

2. This Court previously ruled that Plaintiff must present expert testimony 

in order to make out a claim of negligence for such a failure.1 In doing so, the Court 

gave Plaintiff additional time to obtain an expert. Following that allowance, Plaintiff 

identified Anthony Grano as their expert, and provided his curriculum vitae and letter 

report dated January 5, 2023, to Defendant. Thereafter, Defendant filed the instant 

motion.

3. Defendant, while couching this motion as one in limine, argues that 

Plaintiff’s expert fails under the Daubert standard for: 1) not being a qualified expert; 

2) providing unreliable opinions and 3) failing to provide an opinion that can assist 

the trier of fact. Plaintiff retorts that his expert is sufficiently qualified and the 

testimony is relevant and will assist the jury in their determination.

4. First and foremost, the Court notes that this motion is not a motion in 

limine, but a Daubert motion. The deadline for Daubert motions have passed, 

however, because Plaintiff was afforded the opportunity to obtain an expert outside 

of the dates prescribed by the Trial Scheduling Order, the Court will allow the motion 

to proceed at this time on its merits.

5. Delaware Rule of Evidence 702 (“D.R.E.”) dictates the admissibility of 

1 Shawn Martin v. Nationwide Railroad Passenger Corporation d/b/a Amtrak, 

N19C-03-038 DJB Docket Item 72.

expert testimony.2 D.R.E. 702 specifically provides that:

A witness who is qualified as an expert by knowledge, skill, 

experience, training, or education may testify in the form of an 

opinion or otherwise, if: (a) the witness is qualified as an expert 

by knowledge, skill, experience, training, or education; (b) the 

evidence is relevant; (c) the expert’s opinion is based upon 

information reasonably relied upon by experts in the particular 

field; (d) the expert testimony will assist the trier of fact to 

understand the evidence or to determine a fact in issue; and (e) the 

expert testimony will not create unfair prejudice or mislead the 

jury.3

6. The trial court acts as the gatekeeper for proffered expert testimony and 

before allowing such testimony, must conclude that the expert opinion testimony is 

both (i) relevant and (ii) reliable.4 Expert testimony is relevant if “it would assist the 

fact finder in understanding the evidence or determining a fact in issue.”5 “Expert 

testimony is reliable if it is premised on technical or specialized knowledge, which 

requires the testimony to be grounded in reliable methods and procedures and 

supported by appropriate validation—i.e., good grounds, based on what is known.”6

7. The proponent of the expert evidence bears the burden of establishing 

its admissibility by a preponderance of the evidence.7 “There is a ‘strong preference’ 

for admitting expert opinions ‘when they will assist the trier of fact in understanding 

the relevant facts or the evidence.’”8

QUALIFICATIONS

8. Grano is the co-founder and executive director of a training provider that 

instructs law enforcement agencies, military units, and security companies in combat 

training, arrest and control methods, and other defensive tactics, which includes the 

use of tasers.

9

 Per Grano, both the Department of Defense (“DoD”) and the InterService Non-Lethal Individual Weapons Instructor Course (“INWIC”) have 

recognized him as a subject matter expert on the use of tasers.10 Grano has been 

providing training to law enforcement and military officers for at least twenty-five 

years.11 As a result, Grano is a qualified expert regarding the appropriateness of the 

use of tasers and when and whether or not police officers should be so equipped with 

this device. Any questions regarding the specific extent of Grano’s experience with

taser instruction goes to the weight of his testimony, not its admissibility.12

RELIABILITY

9. The Unites States Supreme Court in Daubert identified a list of nonexclusive factors for trial courts to consider in determining the reliability of expert 

opinion testimony: 

(1)Whether a theory or technique has been tested;

(2)Whether it has been subject to peer review and publication; 

(3)Whether a technique had a high known or potential rate of 

error and whether there are standards controlling its operation; 

and

(4)Whether the theory or technique enjoys general acceptance 

within the relevant scientific community.13

10. Given that many fields of expertise are not subject to peer review and 

publication, Delaware courts instruct against the rigid application of Daubert factors 

to determine reliability of expert evidence.14 As a result, trial courts possess “broad 

12 See Rodriguez v. State, 30 A.3d 764, 769-70 (Del. 2011) (“Like expert witnesses 

generally, an analyst’s lack of proper training or deficiency in judgment may be 

disclosed in cross-examination. By probing Hegman on his particular experience in 

tire track and shoeprint analysis, defense counsel challenged his credibility before the 

jury and the weight to be given the impression evidence.” (internal citations 

omitted)).

latitude” in making such determinations.15 “The factors will be applied flexibly 

where a proffered witness’s area of expertise is not expected to carry the traditional 

indicia of scientific acceptance; however, reliability remains a prerequisite to 

admissibility of all expert opinions, whether they are based upon scientific, technical, 

or other specialized knowledge.”16 

11. Grano’s opinion on whether use of a taser would have prevented 

Plaintiff’s injuries is non-scientific. To determine reliability in the non-scientific 

opinion context, Delaware courts have looked to whether the “opinions have a 

reliable basis in [the expert’s] knowledge and experience” and whether the “report 

explains how that knowledge and experience informed his opinions regarding the 

case.”17

12. In developing his report, Grano relied upon the complaint, video 

evidence, and multiple depositions taken in the case.18 No other supportive materials 

were referenced or provided in the report.19 Though the report does not explicitly

to further understand the evidence and found the witness to be a skilled person by 

training and experience.” (internal quotation marks omitted)).

detail his source of knowledge, Grano presumably relied upon his knowledge and 

experience in the use of tasers and defensive tactics in reaching his opinion. Grano 

explains that a taser’s effect, rendering a subject immobile for a limited period of 

time, is an “immeasurable asset” to law enforcement and “results in less officer 

injuries[.]”20 Taken together, Grano proffers a reliable basis of knowledge and 

experience and explained how his knowledge of tasers informed his ultimate 

opinion.21

TESTIMONY WILL ASSIST THE JURY

13. Amtrak further contends that Grano’s expert testimony will not assist 

the jury because it has no bearing on “whether Amtrak breached any applicable 

standard of care in relation to the issuance of Tasers.”22 As a result, Amtrak asserts 

that Grano’s opinion will confuse the issue and mislead the jury. Plaintiff asserts that 

under FELA, the jury must decide whether Amtrak failed to provide a safe place to 

work for its employees and that Grano’s opinion is relevant to the jury’s 

determination of a safe workplace.

20 Id.

21 See e.g., M & G Polymers, 2009 WL 3535466, at *10-11; Jones, 2003 WL 

21519842, at *3; see also Blessing v. Williams, 2022 WL 4182534, at *16 (M.D. Fla. 

Sept. 13, 2022) (“But the most important test of an experience-qualified nonscientific expert’s reliability is that the expert must be able to explain how [his] 

experience leads to the conclusion reached, why that experience is a sufficient basis 

for the opinion, and how that experience is reliably applied to the facts.” (internal 

quotation marks and citations omitted).

14. Given the context, subject matter and his qualifications, Grano’s opinion 

will assist the jury. Liability under FELA stems from the railroad employer’s duty 

to provide a reasonably safe workplace.23 Accordingly, Grano’s opinion will assist 

the jury in determining whether Amtrak’s decision not to equip officers with tasers 

breached its duty to provide a safe working environment. 

15. As a result, the Motion to Exclude Grano’s Testimony is 

DENIED.

IT SO ORDERED this 15

TH day of June, 2023.
