Rocanelli, J.
      This case involves allegations of exposure to toxic substances in the

workplace. From 1996 to 2016, Gregorio Sanchez Valdez (“Valdez”) worked as a

machinist for Defendant BNSF Railway Company f/k/a Burlington Northern and

Santa Fe Railway Company (“BNSF”). On October 9, 2014, Valdez was diagnosed

with laryngeal cancer. Valdez alleges that his cancer was the result of his exposure

to various toxic substances and carcinogens during the course of his employment

with BNSF.

      This lawsuit was filed September 29, 2017. Service of process on BNSF was

accomplished on July 20, 2018. In the meantime, Valdez died and his estate was

substituted as Plaintiff (the Estate of Gregorio Sanchez Valdez is also referenced

herein as “Valdez”).

      Valdez has identified two expert witnesses to support his claims: (i) Philip A.

Smith, MPH, Ph.D., CIH, FAIHA, for the standard of care for railroad employers

(“Liability Expert”) and (ii) Theron Blickenstaff, M.D., M.P.H., F.A.C.E.M., for the

causal relationship between Valdez’s exposure to toxic substances and his cancer

(“Medical Causation Expert”).

      BNSF seeks summary judgment on the ground that this lawsuit is time-barred.

Specifically, BNSF claims that this lawsuit was not commenced until BNSF was

served with process. In addition, BNSF challenges Valdez’s expert witnesses and

seeks orders from the Court limiting and/or precluding the experts’ testimony at trial.

BNSF also seeks judgment as a matter of law on the grounds that Valdez cannot

                                          1
prove his case without the testimony of the expert witnesses which BNSF seeks to

exclude. Valdez opposes BNSF’s motions and contends that his lawsuit is not time-

barred, and that the opinions of his expert witnesses meet the Daubert standard.

    I.      Whether This Lawsuit is Time-Barred is Controlled by a Genuine
            Issue of Material Fact that Must be Submitted to a Jury

         The Court may grant summary judgment only where the moving party can

“show that there is no genuine issue as to any material fact and that the moving party

is entitled to judgment as a matter of law.”1 A genuine issue of material fact is one

that “may reasonably be resolved in favor of either party.”2 The moving party bears

the initial burden of proof and, once that is met, the burden shifts to the non-moving

party to show that a material issue of fact exists.3 At the motion for summary

judgment phase, the Court must view the facts “in the light most favorable to the

non-moving party.”4 Summary judgment is only appropriate if the plaintiff’s claims

lack evidentiary support such that no reasonable jury could find in the plaintiff’s

favor.5

         BNSF argues Valdez’s claim is time-barred under the statute of limitations of

the Federal Employers’ Liability Act (“FELA”) because Valdez failed to serve

BNSF with process within the three-year statute of limitations. This lawsuit was

filed September 29, 2017. Service of process on BNSF was accomplished on July

20, 2018.

      BNSF claims Valdez’s cause of action accrued on October 9, 2014, the date

Valdez was diagnosed with laryngeal cancer. According to BNSF, this lawsuit is

time-barred because the action was not “commenced” within 3 years of October 9,

2014. Specifically, BNSF argues that, even though the lawsuit was filed within three

years of Valdez’s diagnosis, because BNSF was not served until ten months later,

the lawsuit is time-barred.

      FELA suits may not be brought “unless commenced within three years from

the day the cause of action accrued.”6 Diligent efforts to serve process are required

by federal decisional law7 as well as Delaware decisional law.8 In this case, service

of process was not accomplished until 10 months after suit was filed.

pending further instruction failed to toll the statute of limitations).

      This lawsuit was filed September 29, 2017. A praecipe was filed with the

complaint,9 but Valdez’s counsel did not request issuance of a writ for service of

process by the Prothonotary. Shortly after the lawsuit was filed, new counsel was

substituted for Valdez. In January 2018, Valdez requested an enlargement of time

to serve BNSF, which was granted by Order dated January 17, 2018, but Valdez still

did not request that a writ for service of process be issued by the Prothonotary. By

letter dated April 18, 2018, Valdez was notified that his lawsuit would be dismissed

for want of prosecution pursuant to Rule 41(e) of the Delaware Superior Court Rules

of Civil Procedure unless some action was taken within 30 days. No action was

taken. The Court entered an Order of dismissal on June 7, 2018.

      At that point, counsel for Valdez leaped into action, filing a motion for relief

from judgment pursuant to Rule 60(b)10 and filing a second motion for enlargement

of time in which to serve BNSF. The Court conducted a hearing on July 10, 2018.

The Court found excusable neglect pursuant to Rule 60(b)(1)11 as grounds to vacate

the Order dismissing the case for want of prosecution.12 The Court also granted an

additional 30 days for Valdez to serve BNSF.13

      On the same day that the Court granted both motions, July 10, 2018, Valdez

filed an alias praecipe and alias summons, and Valdez also filed the necessary

paperwork to cause the Prothonotary issue a writ for service of process. The writ

was issued promptly by the Prothonotary, on July 16, 2018. BNSF was served within

just a few days, on July 20, 2018.

      Given the delay between filing the lawsuit on September 29, 2017 and service

of process on BNSF on July 20, 2018, there may be a question of whether Valdez

was sufficiently diligent in commencing this action. However, the question of

diligence does not even have to be reached if Valdez’s claim accrued within 3 years

of the date of service – no sooner than July 20, 2015 – because then the action was

commenced in a timely manner even if the date of service of process is considered

the commencement date. The question, therefore, is when did Valdez’s claim

accrue?

      In cases such as this, where the plaintiff may have been exposed to toxic

substances years before any symptoms arise, the United States Supreme Court has

adopted a “discovery rule” for determining the date the cause of action accrued.14

Under the “discovery rule,” the statute of limitations “begins to run when the

plaintiff knows or has reason to know of the existence and cause of the injury which

14
  See Matson v. Burlington N. Santa Fe R.R., 240 F.3d 1233, 1235 (10th Cir. 2001)
(citing United States v. Kubrick, 444 U.S. 111, 121–23 (1979)).
                                         5
is the basis of his action.”15 The discovery rule is applicable whether the decisional

law under FELA is applied16 or if Delaware law17 controls the inquiry.

      The question of when Valdez knew or should have known that his laryngeal

cancer was the result of exposure to toxic substances in the BNSF workplace is

disputed. Where, as here, there is a genuine dispute regarding a material fact,

summary judgment is not appropriate. Furthermore, applying the discovery rule

requires a fact intensive inquiry that must be submitted to the jury.18 Therefore, if

   Urie v. Thompson, 337 U.S. 163, 170 (1949) (explaining that “no specific date of
contact with the substance can be charged with being the date of injury, inasmuch as
the injurious consequences of the exposure are the product of a period of time rather
than a point of time; consequently the afflicted employee can be held to be ‘injured’
only when the accumulated effects of the deleterious substance manifest
themselves”); United States v. Kubrick, 444 U.S. 111, 122 (1979) (The Court is
“unconvinced that for statute of limitations purposes a plaintiff’s ignorance of his
legal rights and his ignorance of the fact of his injury or its cause should receive
identical treatment. That he has been injured in fact may be unknown or unknowable
until the injury manifests itself; and the facts about causation may be in the control
of the putative defendant, unavailable to the plaintiff or at least very difficult to
obtain.”); see Kindred v. Burlington N. R.R. Co., 742 So.2d 155, 157 (Ala. 1999)
(interpreting both Urie and Kubrick “to mean that a FELA claim accrues, and the
statutory period of limitations begins to run, when the plaintiff possess sufficient
critical facts from which the injury and its cause, including its work-relatedness,
should be plainly known”) (internal quotations omitted).

asbestos exposure”). See Hunt v. Union Pac. R.R. Co., 2017 WL 5664813, at *3

(Collins), 673 A.2d at 163 (providing that “[w]hen either plaintiff’s knowledge or
                                            6
BNSF wishes to present this factual dispute at trial, then the jury will be asked to

apply the discovery rule to determine the date on which Valdez knew or should have

known that his cancer was caused by exposure to toxic substances during his

employment by BNSF as a machinist.19

   II.     Valdez’s Proposed Expert Witnesses Meet the Daubert Standard

           1. The Daubert Standard for Admissibility of Expert Opinions

         The admissibility of expert testimony is governed by Delaware Rule of

Evidence 70220 as well as the Daubert standard which requires the trial court to

the reasonableness of his actions are in dispute in the light of conflicting evidence in
the record the issue is best left to the jury[ i]t is only when the record is
uncontroverted that the plaintiff ‘discovered’ his injury . . . that summary judgment
is appropriate”).
19
    The Court will not determine at this time whether the lawsuit was timely
commenced if the jury finds that Valdez knew or should have known that his throat
cancer was related to toxic substances in the workplace sometime between October
9, 2014, the date Valdez was diagnosed with laryngeal cancer, and July 20, 2015,
which is three years from the date for service of process. However, the Court notes
that a finding of excusable neglect was made by the Court in connection with
vacating the order of dismissal, which may be controlling as law of the case. See
Frank G.W. v. Carol M.W., 457 A.2d 715, 718 (Del. 1983) (“[T]he doctrine of the
law of the case normally requires that matters previously ruled upon by the same
court be put to rest.”). Depending on the jury’s ruling, this legal question may be
addressed pursuant to Superior Court Civil Rule 50.
20
   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 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.
D.R.E. 702.
                                            7
determine whether the proposed evidence is both “relevant” and “reliable.”21 The

reliability prong tests whether an expert has a reliable basis in the knowledge and

experience of the relevant discipline.22

      In addition to the Daubert factors, Delaware requires the trial judge to

consider an additional five-step test to determine the admissibility of expert

testimony.23 The trial judge must determine that:

      (1) the witness is qualified as an expert by knowledge, skill, experience,
          training, or education;

      (2) the evidence is relevant;

      (3) the expert’s opinion is based upon information reasonably relied
          upon by experts in that particular field;

      (4) the expert testimony will assist the trier of fact to understand the
          evidence or determine a material fact in issue; and

      (5) the expert testimony will not create unfair prejudice or confuse or
          mislead the jury.24

      The party seeking to introduce expert testimony bears the burden of

establishing admissibility by a preponderance of the evidence.25 The decision to

admit expert testimony is not a conclusion that the expert’s opinion is correct.

Rather, the trial judge’s role as gatekeeper26 is limited to determining “whether the

proponent of the evidence has demonstrated that scientific conclusions have been

generated using sound and reliable approaches.”27 Expert opinions are admissible

where they assist the trier of fact in understanding the facts or evidence presented at

trial28 and are otherwise the relevant product of reliable methodology.29 “Once the

trial court has determined that a witness is competent to testify as an expert,

challenges to the expert’s skill or knowledge go to the weight to be accorded the

expert testimony rather than its admissibility.”30 “Weight and credibility challenges,

on the other hand, relate to an expert’s skill or knowledge in being able to tie the

facts of the case to the opinion he or she plans to give.”31

          2. Valdez’s Liability Expert: Smith, M.P.H., Ph.D., C.I.H., FAIHA.

      First, as a threshold matter, BNSF challenges the reliability of Valdez’s

Liability Expert, Philip Smith. According to BNSF, Liability Expert’s opinions are

inherently unreliable. The Court is satisfied that Valdez’s Liability Expert is an

                                          9
expert qualified by knowledge, skill, experience, training, and education.          In

addition, the testimony of Liability Expert is relevant and will assist the jury in

understanding the evidence and determining a fact in issue. The opinions of Liability

Expert are based on information reasonably relied on by experts in the field. The

opinion of Liability Expert will not create unfair prejudice or confuse or mislead the

jury. Therefore, the testimony of Liability Expert is admissible.

         Second, BNSF also submits that it is entitled to summary judgment because

Valdez has failed to produce a liability expert competent to testify at trial. In other

words, according to BNSF, if the Court agrees and rules in its gatekeeping function

that Valdez’s Liability Expert does not meet the Daubert standard, then judgment

should be entered on behalf of BNSF because Valdez cannot present a prima facie

case at trial without a liability expert. As the Court has found the testimony of

Liability Expert to be admissible, BNSF’s summary judgment argument based upon

Valdez’s failure to produce a liability expert fails.

         Third, BNSF moves in limine to preclude so-called legal conclusions by

Liability Expert. Specifically, BNSF argues it is improper for Liability Expert to

conclude that BNSF failed to comply with the General Duty Clause set forth in the

Occupational Safety and Heath Act (“OSHA”).32 In the alternative, BNSF argues

32
     OSHA’s General Duty Clause states:
        (a) Each employer—
                  (1) shall furnish to each of his employees employment and a place
                      of employment which are free from recognized hazards that are
                                           10
this opinion is not relevant and/or the opinion’s probative value is outweighed by

unfair prejudice and confusion. The Court disagrees. The evidence of BNSF’s

alleged failure to comply with the OSHA General Duty Clause is relevant 33 and its

probative value substantially outweighs the danger of unfair prejudice, confusing the

issues or misleading the jury.34 To prevail, Valdez must prove the elements of

negligence: duty, foreseeability, breach, and causation.35 As the safety standards set

forth in the General Duty Clause effect what are considered reasonable safety

precautions in the railroad industry, the OSHA General Duty Clause is relevant, has

probative value, and satisfies the necessary balancing test.

      Therefore, the Court is satisfied that Liability Expert is an expert qualified by

knowledge, skill, experience, training, and education. In addition, the testimony of

Liability Expert is relevant and will assist the jury in understanding the evidence and

determining a fact in issue.       The opinions of Liability Expert are based on

                      causing or are likely to cause death or serious physical harm to
                      his employees;
                  (2) shall comply with occupation safety and health standards
                      promulgated under this chapter.
29 U.S.C. § 654.
33
    Under the Delaware Rules of Evidence, “relevant evidence” means evidence
having “any tendency to make a fact more probable or less probable than it would
be without the evidence; and the fact is of consequence in determining the action.”
D.R.E. 401.
34
   Under Delaware Rule of Evidence 403, “[t]he court may exclude relevant evidence
if its probative value is substantially outweighed by a danger of . . . unfair prejudice.”
D.R.E. 403.
35
   See Consol. Rail Corp. v. Gottshall, 512 U.S. 532, 540 (1994) (stating that under
FELA, courts should apply the traditional elements of negligence).
                                            11
information reasonably relied on by experts in the field. The opinion of Liability

Expert will not create unfair prejudice or confuse the issues or mislead the jury. 36

The challenges to Liability Expert presented by BNSF are addressed to the weight

and credibility of the proposed testimony and not to admissibility. BNSF may

effectively cross-examine Liability Expert to challenge the weight of the evidence.

          3. Valdez’s Medical Causation Expert: Blickenstaff, M.D., M.P.H.,
             F.A.C.E.M.

      BNSF challenges the reliability of Valdez’s Medical Causation Expert who

states that Valdez’s cancer was caused by exposure in the BNSF workplace to

asbestos and diesel exhaust.37 The opinion of Medical Causation Expert is

challenged by BNSF which argues that Medical Causation Expert’s opinions are

inherently unreliable and not based on peer-reviewed methodology that is accepted

in the relevant field. Valdez opposes this motion and contends Medical Causation

Expert’s opinions are reliable because the opinions are based on peer-reviewed

scientific and medical literature; analysis of all witness testimony in this case;

industrial hygiene literature regarding hazardous exposures of railroad workers; and

specific expert liability opinions of Valdez’s Liability Expert.

36
  See D.R.E. 403.

diesel exhaust. Valdez v. BNSF Ry. Co., Del. Super., C.A. No. N17C-09-299,

                                          12
      Medical Causation Expert relies on a report from the International Agency for

Research on Cancer (“IARC”). The IARC is:

             [P]art of the World Health Organization. Its mission is to
             coordinate and conduct research on the causes of human cancer,
             the mechanisms of carcinogenesis, and to develop scientific
             strategies for cancer control. The Agency is involved in both
             epidemiological and laboratory research and disseminates
             scientific information through publications, meetings, courses,
             and fellowships.38

      Monographs published by the IARC “identify environmental factors that are

carcinogenic hazards to humans. These include chemicals, complex mixtures,

occupational exposures, physical agents, biological agents, and lifestyle factors.

National health agencies can use this information as scientific support for their

actions to prevent exposure to potential carcinogens.”39

      IARC Monograph No. 105 deals specifically with diesel exhaust and its

carcinogenicity.40 Monograph No. 105 is a catalog of many studies on the subject

of diesel fumes and its harmful effects, including the association between diesel

exhaust and cancer.41 Specifically, Medical Causation Expert references the IARC

for the case-controlled studies that showed a statistically significant odds ratio for

individuals with laryngeal cancer who were exposed to diesel exhaust.42

      BNSF submits that Monograph No. 105 is not reliable as support for the

association between diesel exhaust and throat cancer. In support, BNSF relies upon

the Delaware Superior Court decision in Wilant v. BNSF Railway Co.43 However,

BNSF’s reliance on Wilant is misplaced because Wilant involved a railroad

employee who had developed bladder cancer. In Wilant, the Court found that the

IARC Monograph did not support the plaintiff’s expert’s opinion. However, in the

case before the Court, the IARC Monograph does support the expert’s opinion with

respect to throat cancer.44

      The Court is satisfied that Medical Causation Expert is an expert qualified by

knowledge, skill, experience, training, and education. In addition, the testimony of

Medical Causation Expert is relevant and will assist the jury in understanding the

evidence and determining a fact in issue. The opinions of Medical Causation Expert

are reliable and are based on information reasonably relied upon by experts in the

particular field of industrial hygiene. The court finds that the opinions of Medical

with exposure to diesel exhaust).
                                         14
Causation Expert will not create unfair prejudice or confuse the issues or mislead

the jury. 45 Therefore, the testimony of Medical Causation Expert is admissible. Any

challenges by BNSF to the weight and credibility of the expert testimony of Medical

Causation Expert may be addressed through cross-examination at trial.

        BNSF also submits that BNSF is entitled to summary judgment because

Valdez has failed to produce a medical causation expert competent to testify at trial.

As the Court has found the testimony of Medical Causation Expert to be admissible,

BNSF’s summary judgment argument based upon Valdez’s failure to produce a

medical causation expert fails.

     III.   BNSF’s Motion in Limine to Preclude the Introduction of or Reference
            to Documents from the American Association of Railroads

        BNSF moves in limine to preclude the introduction or reference to documents

from the American Association of Railroads (“AAR”). BNSF argues the AAR

documents are inadmissible hearsay, cannot be authenticated and are irrelevant.

Valdez opposes this motion and contends that the AAR documents may be relied

upon by its expert witnesses, including to demonstrate notice of potential hazards to

employees, while acknowledging that the AAR documents are not admissible as

substantive evidence.

        A more well-developed record is required to ascertain whether it is

appropriate for Valdez’s expert witnesses to reference reliance on the AAR

45
     See D.R.E. 403.
                                         15
documents at trial. At a minimum, a proper foundation must be laid. Certainly, the

AAR documents are hearsay and will not be admitted as substantive evidence but

the question of whether the probative value of reference to the AAR documents

substantially outweighs the danger of unfair prejudice, confusing the issues or

misleading the jury46 will be resolved in the context of the trial using the evidentiary

considerations that are well-settled in Delaware.47

                                   CONCLUSION

      This matter shall proceed to trial where each party may engage in robust

challenges to the evidence presented by the opposing party. The jury shall decide

when Valdez knew or should have known that his cancer was caused by workplace

exposure to the toxic substances at issue. Challenges to the weight of evidence may

be presented through vigorous cross-examination and argument.
