    On Appeal from the 333rd District Court
    Harris County, Texas
    Trial Court Case No. 2006-76611
    OPINION ON EN BANC RECONSIDERATION
    We grant Appellants’ motion for en banc reconsideration. The opinion and
    judgment issued on August 30, 2018, is hereby withdrawn, and this en banc
    opinion and judgment are issued in their stead.
    Approximately 20 years ago, there was a significant increase in the number
    of suits filed in Texas courts alleging injury from silica exposure. In 2005, the
    4
    Texas Legislature created a Silica multidistrict litigation pretrial docket that
    established procedures for individual claims to advance to trial.1
    Under the provisions of the Silica MDL statute in chapter 90 of the Civil
    Practice and Remedies Code, each silica claim already pending on August 31,
    2005 would remain in the MDL until that particular claimant submitted a medical
    report complying with certain statutory requirements. If a compliant medical report
    was submitted and approved by the MDL Court, that claim would then be
    remanded to the district court for trial. If no medical report was filed, the claim
    would remain pending in the MDL indefinitely.
    Appellants are 106 sandblasters whose already-pending silica claims were
    transferred into the MDL once it was formed. Their claims remained pending in
    the MDL for more than 10 years without medical reports being submitted.
    As originally enacted, the MDL statute had no provision for involuntary
    dismissal of silica claims that predated the MDL and were later transferred into it;
    however, the statute was amended in 2013 to allow for the dismissal without
    prejudice of pre-2005 claims if claimants failed to file qualifying medical reports
    by a statutorily specified deadline.
    Facing dismissal under the new statutory provision, the sandblasters filed
    their individual medical reports in 2013. Significantly, these medical reports were
    1
    See TEX. CIV. PRAC. & REM. CODE § 90.001–.012; Act of May 16, 2005, 79th
    Leg., R. S., ch. 97, § 1, 2005 Tex. Gen. Laws 169.
    5
    not prepared contemporaneously with their filing. Two-thirds of them were
    prepared before May 2005, which means they were written before enactment of the
    statute that specifies the required content of a medical report for approval by the
    MDL Court. The remaining one-third were prepared after the statute was
    enacted—between mid-2005 and 2008.
    After the sandblasters filed their medical reports, the Silica MDL defendants
    filed individual and global objections to the medical reports, contending the reports
    failed to meet various statutory requirements of Chapter 90. The defendants then
    moved to dismiss all 106 sandblasters’ suits for failure to comply with statutory
    requirements by the deadline specified in the 2013 amendment. The MDL Court
    sustained almost all objections and dismissed all the sandblasters’ claims without
    prejudice to refiling. The cases were consolidated, and the sandblasters appealed
    the dismissal of their claims.
    In nine issues, the sandblasters argue that Chapter 90 is unconstitutional. We
    affirm.
    Background
    A Rule 13 pretrial MDL was created in 2004 when the Judicial Panel on
    Multidistrict Litigation determined the then-pending 71 suits filed by 453 plaintiffs
    against 158 defendants involved one or more common questions of fact and
    transfer would be for the convenience of the parties and witnesses and would
    6
    promote the just and efficient conduct of the cases. In re Silica Prods. Liab. Litig.,
    
    166 S.W.3d 3
    , 5–9 (Tex. M.D.L. Panel Nov. 10, 2004); see TEX. R. JUD. ADMIN.
    13.
    In 2005, the Legislature enacted Chapter 90 of the Civil Practice and
    Remedies Code. TEX. CIV. PRAC. & REM. CODE § 90.001–.012; Act of May 16,
    2005, 79th Leg., R. S., ch. 97, § 1, 2005 Tex. Gen. Laws 169. The new legislation
    created a statutory MDL for silica-related claims. 
    Id. Under the
    terms of the
    statute, individual cases were held in the MDL until the plaintiffs submitted
    medical reports that met all listed statutory requirements. 
    Id. § 90.010(d)
    (providing for cases to remain in MDL until report is filed); see 
    id. § 90.004
    (specifying required content of medical report for approval). After a qualifying
    medical report was submitted and approved by the MDL Court, a case would be
    returned to the district courts for trial. 
    Id. § 90.010.
    All 106 of the sandblasters who are appealing dismissal of their suits had a
    claim pending in the Rule 13 MDL in 2005 when Chapter 90 was enacted. Their
    claims were then transferred to the statutory Silica MDL where they remained for
    over 10 years without remand for trial.
    The purpose behind Chapter 90
    The Legislature included official comments when it enacted Chapter 90. 
    Id. § 1,
    cmts. a–n. According to the official comments, individuals who have been
    7
    exposed to silica may have “markings on [their] lungs that are possibly consistent
    with silica exposure, but the individual has no functional or physical impairment
    from any silica-related disease.” 
    Id., cmt. m.
    The discovery of these markers can
    trigger a statute of limitations problem for the exposed individuals. 
    Id. Individuals’ efforts
    to avoid limitations problems led to a “crush” of suits being filed in the
    courts on behalf of workers who have shown some signs of exposure but have “no
    current impairment and may never have impairment.” 
    Id., cmts. g,
    m.
    The large number of filings has been described as a “situation [that] has
    reached critical dimensions and is getting worse.” 
    Id., cmt. d.
    To “prevent[] scarce
    judicial and litigant resources from being misdirected by the claims of individuals
    who have been exposed to . . . silica but have no functional or physical impairment
    from . . . silica-related disease,” the Legislature enacted Chapter 90, aimed at
    “protect[ing] the right of people with impairing . . . silica-related injuries to pursue
    their claims for compensation in a fair and efficient manner through the Texas
    court system.” 
    Id., cmt. n.
    Chapter 90 created a bifurcated system to allow those
    with confirmed impairment to proceed to trial while those without a confirmed
    impairment would remain in the MDL, without any statute-of-limitations
    ramifications, until an impairment was confirmed. Id.; see 
    id. § 90.010(d)
    (providing that cases remain in MDL without dismissal until qualifying
    impairment is established).
    8
    Section 90.004
    Section 90.004 requires that certain information be included in a claimant’s
    medical report to qualify for remand to district court for trial and, after the 2013
    amendment, to avoid dismissal. The statute requires medical reports based on silica
    exposure to be prepared by board-certified physicians and to include specific
    verifications and findings by the report’s authoring physician. See 
    id. § 90.004
    .
    The physician must (1) verify that she or a medical professional employed by and
    under her direct supervision and control (a) performed a physical exam of the
    claimant, (b) took a detailed occupational and exposure history, including the
    claimant’s principal employments, exposure to airborne contaminants, and the
    “nature, duration, and frequency” of exposure, and (c) took a detailed medical and
    smoking history, including the claimant’s “past and present medical problems and
    their most probable cause”; and (2) set out in her report the claimant’s
    “occupational, exposure, medical, and smoking history.” 
    Id. § 90.004(a)(1)–(2),
    (e).
    The physician must also verify the claimant has “one or more” of the
    following: (1) “a quality 1 or 2 chest x-ray that has been read by a certified B-
    reader according to the ILO system of classification[2] as showing . . . bilateral
    2
    Chapter 90 defines “ILO system of classification” as “the radiological rating
    system of the International Labor Office in ‘Guidelines for the Use of ILO
    9
    predominantly nodular opacities (p, q, or r) occurring primarily in the upper lung
    fields” with a specified “profusion grading”; (2) “pathological demonstration of
    classic silicotic nodules exceeding one centimeter in diameter as published in
    ‘Diseases Associated with Exposure to Silica and Nonfibrous Silicate Minerals,’
    112 Archives of Pathology and Laboratory Medicine 7 (July 1988)”;3
    (3) “progressive massive fibrosis radiologically established by large opacities
    greater than one centimeter in diameter”; or (4) “acute silicosis.” 
    Id. § 90.004(a)(3).
    In addition to these verifications, detailed statements, and medical
    conclusions, the physician’s report must be “accompanied by copies of all ILO
    classifications, pulmonary function tests, including printouts of all data, flow
    volume loops, and other information demonstrating compliance with the
    equipment, quality, interpretation, and reporting standards set out in this chapter,
    lung volume tests, diagnostic imaging of the chest, pathology reports, or other
    International Clasification of Radiographs of Pneumoconioses’ (2000), as
    amended.” TEX. CIV. PRAC. & REM. CODE § 90.001(11).
    3
    In September 2005, the MDL Court provided an interpretation of the statute to all
    parties, which is in the clerk’s record, memorializing that the parties had agreed
    the “original statutory language ‘nodules exceeding one centimeter’” should read
    “nodules less than 1 cm in diameter.” There is no indication in the record that any
    party objected to this statement or sought an alternative statutory interpretation
    from the MDL Court.
    10
    testing reviewed by the physician in reaching the physician’s conclusions.”4 
    Id. § 90.004(a)(4).
    For silicosis claims, the statute requires physician verification of a
    claimant’s impairment. 
    Id. § 90.004(b).
    The physician must verify that (1) there
    has been a sufficient latency period for the type of silicosis alleged; (2) the
    claimant has “at least Class 2 or higher impairment due to silicosis, according to
    the American Medical Association Guides to the Evaluation of Permanent
    Impairment and reported in 20 C.F.R. Part 404, Subpart P, Appendix 1, Part (A),
    Sections 3.00(E) and (F) (2003)”; and (3) the physician has concluded the medical
    findings and impairment “were not more probably the result of causes other than
    silica exposure” as possibly signified by the claimant’s occupational, exposure,
    medical, and smoking history. 
    Id. For silica-related
    lung cancer and another silica-
    related disease, the statute lists additional requirements. § 90.004(c)–(d).
    Thus, to qualify under Section 90.004, a claimant’s medical report must
    contain certain, specific findings, diagnoses, and verifications by the board-
    certified physician who authors the report. The content of the report must be based
    on the claimant’s physical examination and pulmonary function testing, and it must
    4
    The same MDL Court statutory-interpretation filing directs that a standard
    pulmonary-function report is not required to include pulmonary-function-testing
    compliance data or detailed printouts of how the tests were performed; however,
    “any PFT [pulmonary function testing] data reviewed by the physician to reach his
    conclusion must accompany the report.”
    11
    take into account the American Medical Association (AMA) Guides, federal
    regulations concerning appropriate testing to establish a respiratory impairment,5
    and a medical article published in the Archives of Pathology and Laboratory
    Medicine.
    Section 90.010
    Section 90.010 directs when a case may transfer from the statutory MDL to
    the trial court. 
    Id. § 90.010.
    It specifically states it applies to Rule 13 MDL cases
    that were pending when Chapter 90 was enacted. 
    Id. §90.010(a). Thus,
    its
    provisions apply to all 106 sandblasters’ claims.
    Section 90.010 requires the statutory Silica MDL Court to retain jurisdiction
    over pending suits and not to remand them for trial until the individual claimants
    file medical reports complying with Section 90.004 or, alternatively, with a limited
    “safety valve” provision found in Section 90.010(f). 
    Id. § 90.010(d)
    ; see 
    id. §90.010(f)–(j). Until
    a qualifying report is filed and approved, the cases remain
    inactive. See 
    id. § 90.010.
    Silica MDL judge’s Section 90.010(k) report
    Section 90.010(k) requires the Silica MDL Court to present a report to state
    government officials five years after statututory enactment that details the total
    number of cases on the docket as well as the number of those cases that do not
    5
    20 C.F.R. Part 404, Subpart P, Appendix 1, Part (A), Sections 3.00(E) and (F)
    (2003).
    12
    meet the criteria for a Section 90.004 compliant medical report; states the Silica
    MDL Court’s “evaluation of the effectiveness of the medical criteria established by
    Section . . . 90.004”; recommends “how medical criteria should be applied”; and
    includes any other administrative information the statutory Silica MDL Court
    deems appropriate. 
    Id. § 90.010(k).
    The Silica MDL Court submitted the required report in September 2010.6
    The judge declined to comment on policy issues related to the statute:
    [A]s to whether the criteria themselves or the minimum levels of
    impairment are appropriate, I am not in a position to ethically opine.
    This is more appropriately a matter for the law makers . . . . It all
    depends on what the law makers of Texas believe the definition of
    “impairment” should be to allow a claimant to proceed in court in
    these cases.
    However, the MDL Court did provide statistical information regarding the
    progression of the docket. As of August 1, 2010, there were 667 cases in the silica
    MDL, representing 5,839 “exposed persons.” Only 54 of the individual claimants
    had filed medical reports under Section 90.004. Only half of those had been
    submitted to the MDL Court for evaluation:

    the MDL had existed.
    Section 90.010(d-1) dismissal procedure
    In 2013, the Legislature amended Section 90.010 to establish a procedure for
    dismissal of silica cases filed before the 2005 legislation was enacted but for which
    no medical report were submitted by a specified deadline. 
    Id. § 90.010(d-1).
    The
    MDL Court could begin dismissing pre-2005 cases for failure to file compliant
    medical reports in September 2014 and was required to complete the dismissals of
    such claims by August 2015. 
    Id. The Legislature
    further amended the statute to provide that dismissals under
    Subsection (d-1) would be without prejudice to the filing of a subsequent action
    14
    and that any refiled action would be treated as through it had never been dismissed.
    
    Id. §§90.010(l)–(n). An
    effort to enjoin the dismissal of claims under Subsection (d-1)
    Before the September 2014 date on which dismissal of pre-2005 cases could
    begin, all 106 sandblasters filed a joint request for injunctive relief, seeking to
    enjoin enforcement of 90.010(d-1). They argued the medical-report requirement
    was “oppressive and unreasonable” and nearly impossible to satisfy. They
    presented various constitutional challenges as a facial challenge to the statute,
    meaning that the statute, by its terms, always operates unconstitutionally. See New
    York State Club Ass’n v. City of New York, 
    487 U.S. 1
    , 11 (1988). The MDL Court
    denied the sandblasters’ motion for injunctive relief for jurisdictional deficiencies.
    A panel of this Court affirmed the MDL Court’s order denying injunctive
    relief, holding that a motion seeking to enjoin a court from enforcing a statute is
    not a proper vehicle to challenge a statute’s constitutionality. In re Tex. State Silica
    Prods. Liab. Litig., No. 01-15-00251-CV, 
    2016 WL 757873
    , *8 (Tex. App.—
    Houston [1st Dist.] Feb. 25, 2016, no pet.) (stating that, when court determines
    statute is unconstitutional, it “does not enjoin itself from enforcing a defective law;
    it merely declares the law unconstitutional.”). After the sandblasters’ interlocutory
    appeal was denied, the case proceeded in the MDL Court.
    15
    The sandblasters began filing their Section 90.004 medical reports as
    required by the 2013 amendment to Section 90.010(d-1) to avoid dismissal.
    Defendants filed general objections and specific objections to individual medical
    reports or subsets of reports. The sandblasters responded. Defendants then filed a
    “motion to dismiss any plaintiff whose medical records are deemed not compliant
    with Chapter 90,” and all parties filed related responses and briefing. The
    sandblasters argued both that their medical reports complied with the statutory
    requirements and that the statute was unconstitutionally vague. The MDL Court
    held a hearing on the pending motions.
    The MDL Court issued its rulings in separate orders for each sandblaster.
    Each order overruled one general objection (as to the timeliness of the medical
    report filings) and sustained all other general and individual objections to that
    sandblaster’s medical report. The MDL Court dismissed each individual
    sandblaster’s claim. By agreement, the cases were consolidated for appeal.
    The sandblasters filed a joint appellate brief, contending Chapter 90 is
    unconstitutionally vague in several respects and is an unconstitutional retroactive
    law.

    Constitutional Vagueness Challenges
    The sandblasters raise five challenges to Chapter 90 premised on a
    constitutional vagueness argument. We consider each argument separately, but
    first, we review the standard for a constitutional vagueness challenge to a civil
    statute.
    A.     Vagueness standard for civil statutes
    Under the United States Constitution, “[i]t is a basic principle of due process
    that an enactment is void for vagueness if its prohibitions are not clearly defined.
    Vague laws offend several important values.” Grayned v. City of Rockford, 
    408 U.S. 104
    , 108 (1972). Vague laws “may trap the innocent by not providing fair
    warning” and can “impermissibly delegate[ ] basic policy matters to policemen,
    judges, and juries for resolution on an ad hoc and subjective basis, with the
    attendant dangers of arbitrary and discriminatory application.” 
    Id. at 108–09.
    To
    avoid these dangers, the Due Process Clause requires that laws be reasonably clear.
    As the United States Supreme Court explained, due process
    ensures that state power will be exercised only on behalf of policies
    reflecting an authoritative choice among competing social values,
    reduces the danger of caprice and discrimination in the administration
    of the laws, enables individuals to conform their conduct to the
    requirements of law, and permits meaningful judicial review.
    Roberts v. United States Jaycees, 
    468 U.S. 609
    , 629 (1984).
    17
    Both the United States Supreme Court and the Supreme Court of Texas have
    applied the principle that statutory language may not be so vague that persons “of
    common intelligence must necessarily guess at its meaning and differ as to its
    application.” Connally v. Gen’l Constr. Co., 
    269 U.S. 385
    , 391 (1926); Tex.
    Antiquities Comm. v. Dallas Cty. Comm’y Coll. Dist., 
    554 S.W.2d 924
    , 928 (Tex.
    1977) (plurality opinion) (quoting same).
    “Although the vagueness standard applies most frequently to penal statutes,
    a civil statute may also be so vague that it violates due process.” Bradley v. State
    ex rel. White, 
    990 S.W.2d 245
    , 252 (Tex. 1999) (Abbott, J., concurring); see A.B.
    Small Co. v. Am. Sugar Ref. Co., 
    267 U.S. 233
    , 239–40 (1925) (explaining that
    rationale stated in previous vagueness cases is not limited to criminal cases
    because “[i]t was not the criminal penalty that was held invalid, but the exaction of
    obedience to a rule or standard which was so vague and indefinite as really to be
    no rule or standard at all”); Tex. Antiquities 
    Comm., 554 S.W.2d at 927
    –28
    (striking down civil statute as unconstitutionally vague). “The degree of clarity that
    the vagueness standard . . . requires ‘varies according to the nature of the statute,
    and the need for fair notice or protection from unequal enforcement.’” 
    Bradley, 990 S.W.2d at 252
    (Abbott, J., concurring); see Vill. of Hoffman Estates v. The
    Flipside, Hoffman Estates, Inc., 
    455 U.S. 489
    , 498 (1982) (in directing that
    vagueness standard not be mechanically applied, stating, “The degree of vagueness
    18
    that the Constitution tolerates—as well as the relative importance of fair notice and
    fair enforcement—depends in part on the nature of the enactment.”).
    There is “greater tolerance of enactments with civil rather than criminal
    penalties because the consequences of imprecision are qualitatively less severe.”
    
    Id. Statutes that
    “do not impose criminal penalties and those that do not threaten to
    inhibit the exercise of constitutionally protected rights are subject to a less strict
    vagueness test.” Raitano v. Tex. Dep’t of Pub. Safety, 
    860 S.W.2d 549
    , 551 (Tex.
    App.—Houston [1st Dist.] 1993, writ denied). A civil statute violates due process
    only if it requires compliance in terms “so vague and indefinite as really to be no
    rule or standard at all.” A.B. Small 
    Co., 267 U.S. at 239
    ; see State ex rel. N.P.N.,
    No. 12-06-00283-CV, 
    2007 WL 1139907
    , at *1 (Tex. App.—Tyler Apr. 18, 2007,
    no pet.) (mem. op.) (quoting same).
    When considering an attack on a statute’s constitutionality, we begin with a
    presumption the statute is valid and the Legislature did not act arbitrarily or
    unreasonably in enacting it. Robinson v. Hill, 
    507 S.W.2d 521
    , 524 (Tex. 1974).
    We must uphold a statute if a reasonable construction can be determined that will
    render it constitutional. Rowan Drilling Co. v. Sheppard, 
    87 S.W.2d 706
    , 707 (Tex.
    1935) (orig. proceeding). The burden rests on the individual challenging a statute
    to prove its unconstitutionality.

    .
    19
    B.     Incorporation of 20 C.F.R. Part 404 into Chapter 90 does not render the
    statute unconstitutionally vague
    There are 106 sandblasters appealing the dismissal of their suit. Of those,
    five do not have medical records in the appellate record. An additional 58
    sandblasters do not have medical records that reflect an impairment rating of Class
    2 or higher. Thus, more than half of the sandblasters cannot establish on this record
    that they submitted medical reports containing the statutorily required impairment
    finding. See TEX. CIV. PRAC. & REM. CODE § 90.010(d-1) (requiring dismissal of
    claims without compliant medical report submitted); § 90.004(b)(2) (requiring
    medical reports for silicosis claimants to contain board-certified physician’s
    verification that “the exposed person has at least Class 2 or higher impairment due
    to silicosis”).
    Defendants asserted objections against more than half of the 106
    sandblasters’ medical reports for failing to include the requisite impairment finding
    and moved for dismissal of those claims. The objections were sustained.
    The sandblasters do not argue the MDL Court erred in concluding some of
    their medical reports did not have the requisite impairment finding. Instead, they
    argue dismissal for this reason is improper because Section 90.004 is
    unconstitutionally vague because the subsection imposing a requirement of a Class
    2 impairment finding refers to the AMA Guides and then references the Code of
    Federal Regulations even though the AMA Guides “are not reported in the
    20
    referenced section of the C.F.R.” The challenged provision requires a silicosis
    claimant to submit a medical report verifying that
    the exposed person has at least Class 2 or higher impairment due to
    silicosis, according to the American Medical Association Guides to
    the Evaluation of Permanent Impairment and reported in 20 C.F.R.
    Part 404, Subpart P, Appendix 1, Part (A), Sections 3.00(E) and (F)
    (2003).
    
    Id. § 9.004(b)(2).
    According to the sandblasters, creating an understanding in a
    reader that a cited material can be found at a location where it cannot be found
    creates a constitutional infirmity in a statute. We cannot agree with their argument
    for two reasons.
    First, we do not read the above provision to suggest that the AMA Guides
    are located in the C.F.R. but, instead, that the impairment determination is to be
    made in accordance with what is reported in the C.F.R. at the specified location.
    The referenced portion of the C.F.R. discusses testing used to evaluate respiratory
    disorders in the context of social security disability determinations. See 20 C.F.R.
    Part 404, Subpart P, Appendix 1, Part (A), Sections 3.00(E) and (F) (2003). There,
    Subsection 3.00(E) explains “[w]hat is spirometry and what are our requirements
    for an acceptable test and report” to demonstrate a respiratory disorder, and
    Subsection 3.00(F) explains “[w]hat is a DLCO [diffusing capacity of the lungs for
    carbon monoxide] test, and what are our requirements for an acceptable test and
    report” in establishing a respiratory disorder. Id.; see also 
    id. Section 3.00(C)(9)
    21
    (defining DLCO). The statute does not purport to provide a citation to where AMA
    Guides can be located and read. Rather, it refers to recognized testing standards
    that apply when making a respiratory-disorder impairment determination.
    Second, even if the reference to the C.F.R. was meant to be a citation for a
    reader to locate the AMA Guides, we fail to see why an incorrect citation would
    render the statute unconstitutionally vague. The sandblasters have not argued they
    are unable to locate copies of AMA Guides from any source and must rely on this
    single citation to find controlling materials. They argue no more than that the
    provided citation does not lead to a recitation of applicable Guides. An incorrect
    citation in this context—which would be analogous to a broken link to an
    otherwise accessible webpage—does not cause Chapter 90 to be unconstitutionally
    vague because it does not leave a person of common intelligence guessing at the
    statute’s meaning or reduce it to no standard or rule at all. See A.B. Small 
    Co., 267 U.S. at 239
    ; Tex. Antiquities 
    Comm., 554 S.W.2d at 928
    .
    We hold that this citation argument does not support a conclusion that
    Section 90.004(b)(2) is unconstitutionally vague. We affirm the dismissal of the 63
    sandblasters who did not submit medical reports with the requisite impairment
    finding. These sandblasters are listed below:

    We will consider the remaining constitutional challenges in light of the

    23
    C.    Requirement that medical report contain verification by report’s
    physician-author regarding the collection of medical and occupational
    history is not unconstitutionally vague
    Defendants objected to the medical history, occupational history, or both
    histories for multiple sandblasters. We affirm the dismissal of 13 sandblasters
    because, first, their medical reports did not contain a verification by the physician-
    author that the physician (or a medical professional employed by and under the
    direct supervision and control of the physician) took a detailed medical and
    smoking history that includes a thorough review of the exposed person’s past and
    present medical problems and their most probable cause and, second, the
    medical/occupational history requirement is not unconstitutionally vague. See TEX.
    CIV. PRAC. & REM. CODE § 90.004(a)(1).
    1.     Meaning of “detailed medical history” and “detailed occupational
    exposure history”
    The sandblasters argue Section 90.004(a)(1)’s requirement that a board-
    certified physician verify she (or a medical professional employed by and under
    her direct supervision) “took a detailed occupational and exposure history from the
    exposed person” and “took a detailed medical and smoking history that includes a
    thorough review of the exposed person’s past and present medical problems and
    their most probable cause” is unconstitutionally vague. See 
    id. § 90.004
    (a)(1)(B–
    C). They attribute the vagueness to the lack of a statutory definition for the terms
    “detailed occupational and exposure history” and “detailed medical . . . history.”
    24
    Chapter 90 contains a definition section in which 29 terms are defined, but
    “detailed occupational and exposure history” and “detailed medical . . . history” are
    not among them. Cf. 
    id. § 90.001
    (defining certain terms used in Chapter 90).
    Nonetheless, Section 90.004 provides guidance on the meaning of these phrases.
    Section 90.004(e) states that the “detailed occupational and exposure history
    required by Subsection (a)(1)(B) must describe . . . the exposed person’s principal
    employments and state whether the exposed person was exposed to airborne
    contaminants, including silica and other dusts that can cause pulmonary
    impairment; and . . . the nature, duration, and frequency of the exposed person’s
    exposure to airborne contaminants, including silica and other dusts that can cause
    pulmonary impairment.” 
    Id. § 90.004(e).
    Section 90.004(A)(1)(C) explains that a
    “detailed medical and smoking history” should include “a thorough review of the
    exposed person’s past and present medical problems and their most probable
    cause.” 
    Id. § 90.004(a)(1)(C).
    We conclude these provisions amply describe what is meant by the statutory
    phrases “detailed occupational and exposure history” and “detailed medical . . .
    history” so as not to be so vague that persons “of common intelligence must
    necessarily guess at its meaning.” See 
    Connally, 269 U.S. at 391
    ; Tex. Antiquities
    
    Comm., 554 S.W.2d at 928
    .
    25
    2.     Verification regarding medical history
    Aside from whether these terms are sufficiently understandable to survive a
    vagueness challenge, there appears to be an incongruence between the objections
    asserted against the medical reports and the sandblasters’ argument with regard to
    their medical histories. For several sandblasters, Defendants asserted an “objection
    to insufficient medical history.” A closer reading of the objection reveals that the
    argument is not that the medical histories lack detail, which is the argument the
    sandblasters appear to respond to with the above vagueness challenge. Instead, the
    objection is that Section 90.004(a)(1)(C) requires the submitted medical report to
    include a physician verification that “the physician or a medical professional
    employed by and under the direct supervision and control of the physician . . . took
    a detailed medical . . . history,” yet the objected-to sandblasters’ medical reports
    have no such verification. There is a medical history, but there is no verification by
    the physician-author that she (or a qualifying medical professional) took the
    medical history. Defendants argue the sandblasters without an appropriate
    verification failed to comply with statutory requirements. This is the objection
    asserted by Defendants and sustained by the MDL Court.
    26
    Our review of the medical records of the remaining 43 claimants reveals 13
    whose medical reports did not include physician verifications.7 The MDL Court
    did not err in sustaining the medical-history objection to these 13 sandblasters, and
    we affirm their dismissal:
    Thomas Benitez                                  David Hollingsworth
    Melvin Briones                                  Juan Morales
    Francisco Dabdub                                Daniel Navejar
    Jessie Duncan                                   Carl Prentice
    Jose Fajardo                                    Jose Rios
    Michael Gary                                    Abelardo Zambrano
    Gerald Henry
    7
    Why these 13 sandblasters’ medical reports lacked verifications might be
    understood, at least in part, by considering the history of this type of litigation and
    taking into account when the medical reports were prepared compared to when the
    MDL statute was enacted. As noted in the official comments to Chapter 90, there
    was a great deal of activity in silica-exposure litigation in the early 2000s, when
    thousands of claims were filed in state district courts because of concerns about
    limitations issues. Those claimants submitted to x-rays and other testing for
    evidence of silica exposure and to physician exams by physicians who then
    prepared contemporaneous medical reports discussing illness diagnoses and
    impairment findings. These medical reports for these 13 sandblasters were
    prepared in 2005, within a few months of Chapter 90 being enacted. Their medical
    reports were not supplemented, as some were for other claimants with older
    reports. Thus, these 13 sandblasters were relying on medical reports prepared at a
    time when the physician-author may not have known Chapter 90’s requirements
    for a qualifying medical report.
    As the sandblasters have noted, there were cost considerations when evaluating
    whether to amend older medical reports before submitting them to the MDL
    Court, but the MDL procedures certainly allowed amended medical reports to be
    filed. The record reflects that, on at least one occasion, a claimant who is not part
    of this appeal filed amended medical reports and then was able to move for
    remand and a trial setting. Still other claimants filed single-page supplements in
    which physicians added the verifications required by Section 90.004. These 13
    sandblasters did not amend or supplement their medical reports, but there was
    nothing in the statute preventing them from doing so.
    27
    This leaves 30 sandblasters.
    D.    Failure to designate the AMA Guides edition that would control
    evaluation of medical reports does not render statute unconstitutionally
    vague
    Defendants objected that some sandblasters’ medical reports did not confirm
    exercise testing as part of their medical evaluations. The MDL Court sustained the
    objections. The sandblasters argue Chapter 90 is unconstitutionally vague because
    the various editions of the AMA Guides are inconsistent regarding the requirement
    of exercise testing and the statute does not specify which edition is to be followed,
    creating uncertainty as to whether the statute requires exercise testing. They argue
    the statute “lacks definiteness or certainty” and violates due process guarantees.
    The record does not support the sandblasters’ uncertainty argument. In
    March 2006, the MDL Court issued a supplement to its recommended checklist for
    medical reports and documentation.8 The supplement states that the fifth edition of
    the AMA Guides to the Evaluation of Permanent Impairment “shall be used to
    determine impairment.” It further states that, “[i]f the AMA publishes a new
    edition of the AMA Guides, the new edition shall apply to medical reports based
    on examinations or testing performed on or after the date of publication of the new
    edition.” And, to further clarify, it adds, “If a new edition is published, medical
    reports that have already been approved under the current [fifth] edition shall not
    8
    The supplement is in the record and was attached to the sandblasters’ response to
    the objections to their medical reports.
    28
    be subject to the new edition.” None of the parties contend the trial court erred in
    determining that the statute requires the application of the guidelines in effect at
    the time of testing.
    To the extent the sandblasters chose to rely on their pre-written medical
    reports, the MDL Court indicated in 2006 their reports would be evaluated under
    the fifth edition’s requirements. If the sandblasters amended their reports, their new
    reports would be evaluated under the version of the AMA Guides in existence
    when the underlying examinations and testing were performed. If the sandblasters
    preferred the impairment criteria in the sixth edition, additional testing and an
    amended report would have brought the reports within its requirements.
    Ten of the remaining sandblasters submitted medical reports that pre-dated
    the 2006 MDL Court supplemental filing, in which the MDL Court stated that
    already-performed medical testing would be analyzed under the fifth edition. None
    of them amended their reports over the next decade. In that context, there was no
    uncertainty whether the fifth edition applied to their reports: it clearly did. Because
    the following sandblasters did not submit medical reports with the required data on
    exercise testing, the dismissal was not error with regard to these 10 sandblasters:
    Noe De La Cruz                                 Daniel Ochoa
    Ronnie L. Johnson                              Humberto Chapa
    Jose Longoria                                  Rudy Encinas
    Victor Perez                                   Dell Hodge
    Roberto Paz                                    Roger Spencer
    29
    This leaves 20 sandblasters.
    E.    Requirement of certain x-ray findings indicating lung abnormalities is
    not unconstitutional
    The    sandblasters’   next    constitutional   argument    is   that   Section
    90.004(a)(3)(A) arbitrarily requires medical reports to contain a finding from the x-
    rays that the claimant’s pulmonary scarring is “predominately nodular” and
    “primarily in the upper lung fields,” even though silicosis can be a lower-lobe
    disease. By requiring these specific findings, they argue, Chapter 90 wrongly
    excludes claimants who have atypical silicosis or pneumoconiosis, which can
    present primarily in the lower lobes of the lungs. They contend these statutory
    limitations are unreasonable, arbitrary, and capricious.
    Subsection (f) of Section 90.010 is referred to as a “safety value” provision.
    It establishes a path to medical-report approval for claimants whose medical
    profiles do not match the Section 90.004 criteria. Under Subsection (f), a claimant
    who cannot meet Section 90.004(a)(3)’s requirements but does comply with
    Section 90.004(a)(1), (2), and (4) has another option: a physician can verify there
    is a physician-patient relationship between the physician-author of the report and
    the claimant, pulmonary function testing was performed, and the physician has
    concluded, to a reasonable degree of medical probability, that the claimant has
    “radiographic, pathologic, or computed tomography evidence establishing bilateral
    pleural disease or bilateral parenchymal disease caused by exposure to . . . silica;

    and . . . has . . . silica-related physical impairment comparable to the impairment”
    the claimant would have had if he had met the criteria in Section 90.004. 
    Id. § 90.010(f)(1)(B).
    Under Subsection (f), neither the “predominantly nodular”
    requirement nor the “primarily in the upper lung fields” requirement applies.
    Compare 
    id. § 90.004
    (a)(3), with § 90.010(f)(1)(B)(iii-iv). Subsection (f) was
    available to sandblasters who did not present with typical findings. None of the
    remaining 20 sandblasters moved for consideration under Subsection (f).
    Sections 90.004 and 90.010 must be analyzed in light of the statute as a
    whole. See Taylor v. Firemen’s & Policemen’s Civil Serv. Comm’n of City of
    Lubbock, 
    616 S.W.2d 187
    , 190 (Tex. 1981). Taking into account Subsection (f),
    which presents an alternative means to establish an injury and impairment, the
    specificity of Section 90.004 does not create an arbitrary approval process that
    denies the sandblasters due process.
    We overrule this constitutional challenge and conclude the MDL Court did
    not err in dismissing the following 20 sandblasters for failure to submit medical
    reports with the requisite findings:

    Delbert Blundell                            Aaron Luke

    Jose Esquivel                               Rene Ramirez

    Homero Garza                                Teodoro Tovar
    Jose Hernandez                              Jose Uresti
    We have concluded the MDL Court did not err in sustaining certain
    objections to various subsets of sandblasters and have overruled the sandblasters’
    constitutional challenges to the statutory provisions on which those particular
    objections were based. We turn next to the sandblasters’ global constitutional
    challenges to Sections 90.004 and 90.010 that are not tied to any specific
    objections.
    Global Constitutional Challenges Not Tied to Any Specific Objections
    Claimants assert two global constitutional challenges to Sections 90.004 and
    90.010.
    A.    MDL Court’s statutory authority to evaluate the sufficiency of medical
    reports does not render Chapter 90 unconstitutionally vague
    The sandblasters challenge the statutory framework of Chapter 90 granting
    the MDL Court authority to determine whether a medical report complies with
    Section 90.004’s requirements. They argue the “framework places the Court in the
    32
    precarious position of rendering medical opinions and providing medical
    interpretation even though the Court has no specialized training in medicine or
    impairment evaluations.” They further argue “the statute allows untrained courts
    and lawyers to interpret highly technical medical articles” without fully
    understanding their content, which denies the sandblasters due process.
    This argument is reminiscent of initial challenges to the expert-reliability
    framework established in Daubert and Robinson. See Daubert v. Merrell Dow
    Pharms., Inc., 
    509 U.S. 579
    (1993); E.I. du Pont de Nemours & Co., Inc. v.
    Robinson, 
    923 S.W.2d 549
    , 557 (Tex. 1995) (rejecting arguments that (1) “judges
    are not competent to assess the scientific reliability” of expert evidence and (2)
    judges should not be cast in “role of amateur scientist”). Since Robinson, a body of
    law has developed that confirms trial judges’ role in assessing the reliability of
    expert opinions and the data underlying their opinions, including evidence
    concerning medical diagnoses and medical causation. See, e.g., Transcont’l Ins.
    Co. v. Crump, 
    330 S.W.3d 211
    , 215–20 (Tex. 2010) (analyzing reliability of
    treating physician’s diagnostic methodology and evaluating whether analytical gap
    exists between plaintiff’s medical data and physician’s causation opinion).
    The sandblasters assert that judges and lawyers are “untrained” in medicine
    and do not have the necessary “specialized training” required to “interpret highly
    technical medical articles” or access “impairment evaluations.” But, Texas courts
    33
    have consistently rejected arguments built on a supposition that trial courts are
    incapable of assessing scientific issues.9 See 
    Robinson, 923 S.W.2d at 557
    –58
    (rejecting contention that judges must be “trained in science to evaluate the
    reliability of a theory or technique”; accepting that judges are “capable of
    understanding and evaluating scientific reliability”); see also Merrell Dow Pharm.,
    Inc. v. Havner, 
    953 S.W.2d 706
    , 713, 730 (Tex. 1997) (stating that courts should
    independently evaluate scientific data underlying expert’s opinion as part of
    determining whether expert’s opinion is reliable).
    In Havner, the Supreme Court of Texas analyzed the scientific data and
    medical literature underlying an expert’s opinion that there is a causal link between
    9
    There are a number of reasons it is appropriate to have judges determine complex
    scientific issues before cases proceed to trial within a crowded docket like an
    MDL. The trial process uses court and litigant resources on particular claimants,
    leaving other claimants waiting in the queue. Those waiting might be more
    impaired than those who reach the trial phase first if there is not a procedure in
    place to prioritize the more seriously ill claimants. The Legislature created a
    separate MDL for silica-based claims and supplemented the judge’s salary in
    recognition that the judge would need to allocate sufficient time to manage the
    docket and analyze complex procedural and scientific issues and evidence. The
    judge has resources available for evaluating evidence that would not be available
    to a jury if the decisional process for determining the adequacy of a gatekeeping
    report was delegated to a jury. The judge has the opportunity to read and study any
    underlying articles and scientific studies supporting medical conclusions, the
    ability to conduct or direct additional research on an issue or to require additional
    hearings or evidence, and, finally, the procedural flexibility to ask questions of
    designated experts and to hire, appoint, and confer with experts beyond those
    designated by the parties. See Harvey Brown, Procedural Issues Under Daubert,
    36 Hous. L. Rev. 1133, 1176–77 (1999) (stating that “a judge may not be smarter
    than a jury, but the judge has resources that are unavailable to the jury” to equip
    the judge to analyze complex expert issues).
    34
    ingestion of a drug during pregnancy and a subsequent birth defect, and the Court
    held there was no scientifically reliable evidence to support the causation opinion,
    meaning there was legally insufficient evidence to support the jury’s verdict
    finding the pharmaceutical company liable for the birth defects. See 
    Havner, 953 S.W.2d at 730
    . As Havner demonstrates, while the task can be daunting at times,
    judges have the duty as gatekeepers to evaluate scientific evidence, medical expert
    opinions, and the data underlying them.
    Section 90.004 requires a medical report to contain various physician
    verifications, set forth relevant histories, contain a diagnosis and impairment
    finding, and attach relevant medical records relied on by the physician in reaching
    her conclusions. See TEX. CIV. PRAC. & REM. CODE § 90.004. We fail to see how a
    statute requiring a court to evaluate the content of a medical report for these items
    is so vague that it is “no rule or standard at all.” See A.B. Small 
    Co., 267 U.S. at 239
    (setting forth civil vagueness standard).
    Nor do we see how the specific scientific area of study addressed in the
    statute—silica-related illnesses and impairment—contributes to vagueness.
    The Texas Supreme Court has noted the similarity between the MDL
    Court’s role under Chapter 90.004 and trial courts’ role, generally, in evaluating
    the reliability of medical experts’ methodologies and underlying data. See In re
    GlobalSanteFe Corp., 
    275 S.W.3d 477
    , 487 (Tex. 2008). The issue in that case
    35
    was whether the Jones Act preempts various Chapter 90 features. See 
    id. In detailing
    the Chapter 90 features, the Court stated that “Section 90.004 tracks
    widely if not universally recognized criteria for reliably diagnosing the existence of
    silica-related illnesses.” 
    Id. The Court
    offered four examples of Section 90.004
    requirements aimed at ensuring reliability: (1) Section 90.004(a)(1)’s requirement
    that a “board-certified physician conduct a detailed occupational and exposure
    history is directed at assuring—early in the litigation so as to conserve judicial and
    litigant resources—that the claim of silica-related injury is supported by medically
    reliable expert review”; (2) Section 90.004(a)(3)’s requirement that the expert
    observe specific findings that are the “standardized method of medical science to
    identify chronic or classic silicosis and distinguishing it from asbestosis”;
    (3) Section 90.004(b)(1)’s requirement that the physician verify a sufficient latency
    period “to assure that the claimant is in fact suffering from a silica-related disease
    under established medical science”; and (4) Section 90.004(a)(3)(A)’s requirement
    that a qualified B-reader make certain findings to further “assure that the reader has
    found at least some abnormality in the x-ray.” 
    Id. Section 90.004’s
    criteria are “directed at assuring reliable expert
    confirmation of the existence of one of the medically recognized forms of silica-
    related illness,” and an expert’s “failure to establish these criteria is grounds for
    rejecting expert testimony under Daubert,” even if the criteria were not
    36
    incorporated into Chapter 90. 
    Id. at 487–88.
    Section 90.004’s requirements
    “represent the Legislature’s attempt to require a medically valid demonstration of
    silica-related disease as opposed to mere exposure to silica or some other substance
    or mere concern that a disease may develop in the future.” 
    Id. at 488.
    The Court also noted “it is vitally important for a physician to take a
    thorough occupational/exposure history and medical history” to “rule out the
    multitude of other causes of the radiographic findings.” 
    Id. The Court
    ’s statements in In re GlobalSanteFe are consistent with our
    conclusion that authorizing a court to evaluate whether a medical report complies
    with Section 90.004’s requirements does not violate the sandblasters’ right to due
    process. We overrule the sandblasters’ constitutional challenge premised on the
    argument that trial courts are incapable of assessing complex medical materials and
    expert medical opinions related to the diagnosis of silicosis and related
    impairment.
    B.    The addition of Section 90.010(d-1) through a 2013 amendment does not
    make the statute an unconstitutional retroactive law
    The sandblasters contend Section 90.010(d-1), which was added to Chapter
    90 in 2013 through a statutory amendment, is an unconstitutionally retroactive law.
    Subsection (d-1) created a procedure, which had not existed under the earlier
    version of Chapter 90, for the dismissal of pre-2005 claims that had been pending
    in the MDL for nearly a decade without medical reports being submitted. See TEX.
    37
    CIV. PRAC. & REM. CODE § 90.010(d-1). Subsection (l) stated dismissal under
    Subsection (d-1) would be without prejudice to refiling. 
    Id. § 90.010(l).
    The sandblasters acknowledge dismissal under Subsection (d-1) for failing
    to file a conforming medical report is without prejudice to refiling; however, they
    assert dismissal is still prejudicial because they will not be able to recapture some
    of the defendants that have already answered and appeared and because dismissal
    will cause them to lose their financial investment in their cases, including already
    incurred costs for filing fees, court records, deposition transcripts, and experts. The
    sandblasters argue the costs associated with these expenses and attorney work
    would be lost if their cases were dismissed.
    1.     Applicable law
    The Texas Constitution prohibits “retroactive law[s].” TEX. CONST. art. I,
    § 16; see Houston Indep. Sch. Dist. v. Houston Chronicle Pub. Co., 
    798 S.W.2d 580
    , 585 (Tex. App.—Houston [1st Dist.] 1990, writ denied) (“Texas law militates
    strongly against the retroactive application of laws.”).
    An unconstitutional retroactive law is one that “takes away or impairs vested
    rights acquired under existing law.” McCain v. Yost, 
    284 S.W.2d 898
    , 900 (Tex.
    1955); see Retroactive law, BLACK’S LAW DICTIONARY (10th ed. 2014) (defining
    as law that “divests vested rights”). A “vested right” is an immediate right or
    entitlement; expectations and contingencies do not qualify. See Kissick v. Garland
    38
    Indep. Sch. Dist., 
    330 S.W.2d 708
    , 712 (Tex. Civ. App.—Dallas 1960, writ ref’d
    n.r.e.). “When the authority granting the right has the power and discretion to take
    that right away, it cannot be said to be a vested right.” Ex parte Abell, 
    613 S.W.2d 255
    , 262 (Tex. 1981); see 
    McCain, 284 S.W.2d at 900
    .
    A statute can apply retroactively and yet not be a “retroactive law” if the
    right it affects did not accrue before the statute became effective. See Houston
    Indep. Sch. 
    Dist., 798 S.W.2d at 585
    .
    2.     The sandblasters have no vested right to the application of the
    pre-amended version of Chapter 90
    The sandblasters’ suits all pre-dated the enactment of Chapter 90. When they
    filed their claims, they were governed by the general rules of procedure and
    evidence and faced the possibility that their claims would be dismissed for want of
    prosecution if they lingered without advancement. See TEX. R. CIV. P. 165a(2)
    (providing that cases not disposed of within applicable time standards may be
    placed on dismissal docket).
    It was after the sandblasters initiated their suits that the Legislature enacted
    Chapter 90’s procedural scheme to permit silica-related claims to remain within the
    court’s jurisdiction, protected from dismissal. See TEX. CIV. PRAC. & REM. CODE
    § 90.010(a)(1), (b), (d). The sandblasters benefitted from this law because their
    claims remained on the MDL docket, in a holding pattern, for more than a decade
    without the risk of dismissal for lack of prosecution. And, the sandblasters received
    39
    a second benefit from the 2005 enactment of Chapter 90: they did not risk going to
    trial when they had lung markings “possibly consistent with silica exposure” but
    “no functional or physical impairment.” They could wait until they had a medically
    verified impairment to go to trial, at which point they would have the potential for
    a larger damages award.
    After the MDL Court submitted its Subsection (k) report in 2010, showing
    that only 54 of over 5,000 claimants had filed medical reports, the Legislature
    amended the statute to add Subsection (d-1) and require claimants to take the next
    step in their case progression or face dismissal. Those who filed qualifying medical
    reports would be remanded to district court for trial; those who did not would be
    dismissed without prejudice to refiling. 
    Id. § 90.010(d-1),
    (l). Staying indefinitely
    in the holding pattern would no longer be an option.
    The statute specifically provides that a claim dismissed under Subsection
    (d-1) and later refiled “is treated for purposes of determining the applicable law as
    if that claimant’s action had never been dismissed but, instead, had remained
    pending until the claimant served a report that complied with . . . Section 90.004 or
    Subsection (f)” of Section 90.010. 
    Id. § 90.010(n).
    Moreover, a claimant dismissed
    under Subsection (d-1) who elected to refile a claim would be given the option to
    use more “cost-efficient” service options when they renewed their claim, such as
    certified mail. See 
    id. § 90.010(o).
    40
    When these sandblasters first asserted their claims, general docketing rules
    controlled and Robinson expert requirements applied. They would have anticipated
    needing to accumulate and present evidence of a medical diagnosis and establish
    medical causation through an expert. They had no “vested right” to have their
    claims remain on a court’s docket indefinitely without producing reliable medical
    evidence of an impairment caused by silicosis. See In re 
    GlobalSanteFe, 275 S.W.3d at 487
    . Nor did the addition of Subsection (d-1) divest them of their right
    to proceed to trial once they had reliable medical evidence. While Section
    90.010(d-1) acts retroactively, it is not an unconstitutional retroactive law that
    divests the sandblasters of vested rights.
    Furthermore, to the extent the sandblasters contend Chapter 90, generally,
    prevents the advancement of their cases due to its medical-report requirements, the
    statute includes Section 90.010(f), which is a “safety value” procedure through
    which sandblasters whose illness progressions do not match medical criteria in
    Section 90.004 may establish an injury through alternative proof, including
    submission of a medical report from a treating physician with equivalent, though
    not identical, findings. 
    Id. § 90.010(f).
    Having concluded Section 90.010(d-1) is not an unconstitutional retroactive
    law, we overrule this final constitutional challenge to the statute.
    41

    We affirm the trial court’s judgment.
