    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.

    at *2 (Del. 1991) (TABLE) (affirming the Superior Court’s ruling that the mere

    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

    Valdez v. BNSF Ry. Co., Del. Super., C.A. No. N17C-09-299, Rocanelli, J. (July
    10, 2018) (ORDER).
    4
    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).

    the plaintiff is chargeable with knowledge that his condition is attributable to
    asbestos exposure”). See Hunt v. Union Pac. R.R. Co.,

    asbestosis and that his asbestosis was work-related); see also In re Asbestos Litig.
    (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

    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.

    The parties have stipulated that the only toxic substances at issue are asbestos and
    diesel exhaust. Valdez v. BNSF Ry. Co., Del. Super., C.A. No. N17C-09-299,

    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).

    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.
