    2                                               MILIK   v. HHS
    Before O’MALLEY, WALLACH, and HUGHES, Circuit Judges.
    O’MALLEY, Circuit Judge.
    Petitioners Marek and Jolanta Milik (collectively, “the
    Miliks”), on behalf of their son, A.M., appeal the final
    judgment of the United States Court of Federal Claims
    affirming a special master’s decision denying compensa-
    tion under the National Childhood Vaccine Injury Act of
    1986 (codified as amended at 42 U.S.C. §§ 300aa-1 to -34)
    (“the Vaccine Act”). Milik v. Sec’y of Health & Human
    Servs., 
    121 Fed. Cl. 68
    (2015). The special master found
    that the Miliks failed to prove by a preponderance of the
    evidence that a measles, mumps, and rubella (“MMR”)
    vaccine caused A.M. to develop a severe neurological
    condition, involving developmental delay, spastic diplegia,
    and motor difficulties. Milik v. Sec’y of Health & Human
    Servs., No. 01-64V, 
    2014 WL 6488735
    (Fed. Cl. Spec.
    Mstr. Oct. 29, 2014) (“Special Master Decision”). Because
    the Court of Federal Claims correctly concluded that the
    special master’s decision was not arbitrary, capricious, an
    abuse of discretion, or otherwise not in accordance with
    law, we affirm.
    I. BACKGROUND
    A. Factual Background
    The relevant facts are primarily those found by the
    special master in his detailed October 29, 2014 decision.
    A.M. was born on December 5, 1993, and was raised in a
    predominately Polish-speaking household. Special Master
    Decision, 
    2014 WL 6488735
    , at *3. At A.M.’s fifteen-
    month routine examination, the pediatrician noted that
    A.M. was “doing well” and was a “well child.” 
    Id. In December
    1995, when A.M. was two years old, his pedia-
    trician noted that “A.M. responded to sound, used 4 to 10
    words (‘mama’ and ‘dada’ were noted specifically), walked
    up stairs, and walked independently.” 
    Id. During subse-
    quent visits in 1996, A.M.’s new pediatrician, Dr. Mitchell
    MILIK   v. HHS                                            3
    Weiler, noted that A.M. could speak several words in
    English. 
    Id. On January
    29, 1998, when A.M. was four years and
    one month old, he received his second MMR vaccination.
    
    Id. Eleven days
    later, A.M. returned to Dr. Weiler’s office
    complaining of a sore throat. “Dr. Weiler diagnosed A.M.
    with pharyngitis (throat swelling) and otitis media (ear
    infection), and treated him with an antibiotic.” 
    Id. Dr. Weiler
    rechecked A.M.’s ears on February 23, 1998. His
    notes from that appointment stated that A.M. had a
    “Trauma. Slipped/Fell” and that he had a limp, but he
    was seen by a podiatrist and the x-rays were negative. 
    Id. at *4.
        On March 2, 1998, A.M. saw Dr. Joseph Maytal, a pe-
    diatric neurologist, for complaints of limping. 
    Id. Dr. Maytal
    made several observations during the examina-
    tion, including that A.M. did not know his last name, he
    only spoke single words in English, and his parents were
    unsure if he could use plurals. 
    Id. Dr. Maytal
    gave A.M.
    a provisional diagnosis of “Ataxia/Unsteadiness and
    Developmental Delay.” 
    Id. He also
    opined that A.M. had
    two issues:
    One is the longstanding issue of this youngster
    who is globally delayed mostly in the lan-
    guage/communicative skills but also in his fine
    motor and possibly in his gross motor skills . . . .
    The second issue is his acute symptoms of “limp-
    ing.” As a precaution I would like to consider the
    reason for his limping . . . with an MRI.
    
    Id. (emphasis added).
    According to Dr. Maytal, the MRI
    showed “diffuse white matter demyelination which is
    consistent with demyelinating process most likely some
    form of leukodystrophy.” 
    Id. In July
    1998, A.M. saw Dr. Krystyna Wisniewski, a
    pediatric neurologist who was part of an interdisciplinary
    4                                              MILIK   v. HHS
    team of specialists at the George A. Jervis Clinic, New
    York State Institute for Basic Research in Developmental
    Disabilities (“IBR”). Dr. Wisniewski noted that A.M.’s
    “cognitive function seems to be appropriate for his chrono-
    logical age. He knows colors, numbers, and follows three
    step commands. His visual perception seems to be im-
    paired.” 
    Milik, 121 Fed. Cl. at 75
    . Dr. Wisniewski diag-
    nosed A.M. with “spastic diplegia, more right than left.”
    Special Master Decision, 
    2014 WL 6488735
    , at *4.
    Dr. Maria Malinowska, a bilingual psychologist,
    evaluated A.M. in September 1998. 
    Id. at *5.
    She deter-
    mined that, at four years and nine months of age, A.M.
    had “motor and speech/language difficulties as well as
    attentional problems.” 
    Id. Dr. Malinowska
    concluded
    that these difficulties “are most likely due to an organic
    brain dysfunction interfere [sic] with his intellectual and
    adaptive functioning.” 
    Id. A.M. also
    saw Dr. Ricardo
    Madrid for a neuromuscular evaluation. Dr. Madrid
    opined that A.M.’s condition was “suggestive but not
    diagnostic of post infectious or post vaccination acute
    encephalomyelitis.” 
    Id. But because
    A.M. did not experi-
    ence seizure, fever, and altered mental state—symptoms
    that are typically expected with a vaccine complication—
    Dr. Madrid doubted that A.M.’s disorder arose from a
    “neurological complication associated with MMR vaccina-
    tion.” 
    Id. The medical
    records provide little information regard-
    ing A.M.’s care after 1998. A group of physicians re-
    evaluated A.M.’s condition beginning in 2011. At that
    time, A.M. was wheelchair-bound and unable to care for
    himself. In March 2012, when he was eighteen years old,
    A.M. saw a specialist in medical genetics who opined that
    “[t]he finding of apparently normal development followed
    by a sudden loss of abilities following an insult with
    severe demyelination is suggestive of vanishing white
    matter disease. This often presents during childhood with
    ataxia following infection or fright.” 
    Id. at *6.
    MILIK   v. HHS                                             5
    B. Procedural History
    The Miliks filed a petition for compensation on Janu-
    ary 31, 2001, on behalf of A.M., alleging that he “suffered
    injuries including spastic diplegia (paraplegia) causing
    [him] to walk with a permanent and debilitating limp,
    severe gross and fine motor difficulties as well as difficul-
    ties learning, all of which were ‘caused-in-fact by admin-
    istration of the MMR vaccination.’” 
    Milik, 121 Fed. Cl. at 70-71
    . The Secretary filed a report opposing the petition
    for compensation. At the Miliks’ request, proceedings
    were delayed for several years to allow time to obtain
    counsel and file expert reports.
    The Miliks filed two expert reports, the first of which
    was a one-page letter from Dr. Logush, a pediatric neurol-
    ogist at the IBR where A.M. was treated. In that letter,
    Dr. Logush stated that A.M.’s history was “suggestive but
    not diagnostic of post infectious or post vaccine, immuno-
    logically induced acute disseminated encephalitis vs.
    encephalomyelitis.” Special Master Decision, 
    2014 WL 6488735
    , at *25. Dr. Logush offered the same conclusion
    after he conducted a follow-up examination of A.M. in
    February 2011. 
    Milik, 121 Fed. Cl. at 77
    . Although Dr.
    Logush participated in a telephone conference with the
    special master where he stated that it was “very probable”
    that the MMR vaccine caused A.M.’s injury, he did not
    ultimately testify as the Miliks’ expert. Special Master
    Decision, 
    2014 WL 6488735
    , at *25.
    The Miliks’ second expert report, filed in November
    2011, was from Dr. Nizar Souayah, the neurologist who
    testified as their expert witness. Dr. Souayah is board-
    certified in neurology, electrodiagnostic medicine, and
    neuromuscular medicine. 
    Id. at *8.
    Dr. Souayah opined
    that A.M.’s condition was “consistent with an extensive
    white matter disease that started approximately 3 weeks
    after MMR vaccination” and that “A.M. suffered an ‘en-
    cephalopathy or encephalitis,’ caused by the MMR vac-
    6                                               MILIK   v. HHS
    cine, at that time.” 
    Id. at *9.
    In both his written report
    and his testimony, Dr. Souayah opined that the MMR
    vaccine caused A.M.’s injury because: (1) A.M. experi-
    enced normal health and development before the vaccine;
    (2) 22 days after receiving the MMR vaccination, A.M.
    developed a limp; (3) no other cause for A.M.’s injury was
    identified, despite extensive testing; and (4) the MMR
    vaccine has been suspected of causing central nervous
    system damage. 
    Id. In response,
    the government filed two expert reports
    from Dr. Michael Kohrman, who is “board-certified in
    neurology and psychiatry, with a special competency in
    child neurology and sleep medicine, and also board-
    certified in pediatrics.” 
    Id. Dr. Kohrman
    opined that
    A.M. had a pre-existing global developmental delay, and
    that his condition is “likely to be a result of a ‘vanishing
    white matter’ disease, such as an unidentified form of
    leukodystrophy, that began around two years of age when
    the first signs of developmental delay appeared.” 
    Id. In the
    alternative, Dr. Kohrman submitted that, even if
    A.M.’s symptoms did not appear until after the MMR
    vaccination, “the cause would still more likely have been
    an infection from which A.M. was suffering at the time,
    rather than his vaccination.” 
    Id. In March
    2013, the special master held an evidentiary
    hearing and heard testimony from Dr. Souayah and Dr.
    Kohrman. Both parties filed post-hearing briefs. A year
    after the hearing, the Miliks filed a motion for considera-
    tion of new medical evidence, seeking to introduce a letter
    from Dr. Maytal, A.M.’s pediatric neurologist. 
    Id. at *7.
    In that letter, Dr. Maytal sought to clarify that his use of
    the term “longstanding” in reference to A.M.’s global delay
    should be interpreted as “a condition existing prior to
    examination,” and that his group was “unable to deter-
    mine the time length of symptoms.” 
    Id. at *12.
    The
    special master admitted the letter over the government’s
    objection.
    MILIK   v. HHS                                           7
    On October 29, 2014, the special master issued a de-
    tailed decision denying the Miliks’ petition for compensa-
    tion. At the outset, the special master noted that,
    although both experts agreed that A.M. suffers from a
    severe developmental disorder, they disagreed as to the
    cause. Weighing the expert testimony, the special master
    found Dr. Kohrman—the government’s expert—more
    persuasive, and credited his opinion that the onset of
    A.M.’s developmental delay preceded the MMR vaccina-
    tion. 
    Id. at *10.
         Recognizing that the parties presented A.M.’s condi-
    tion as a single global entity involving both mental delay
    and physical problems, and that the Miliks never argued
    that they were distinct injuries, the special master found
    no evidentiary basis to conclude that part of A.M.’s disa-
    bility was vaccine-caused. 
    Id. at *27.
    1 Accordingly, the
    special master concluded that the Miliks had not shown
    by preponderant evidence that the MMR vaccination
    caused A.M.’s disorder. 
    Id. at *27-28
    (citing Althen v.
    Sec’y of Health & Human Servs., 
    418 F.3d 1274
    , 1278
    (Fed. Cir. 2005)). In the alternative, the special master
    found that: (1) A.M. did not suffer an encephalopathy or
    encephalitis; (2) even if he did, the more likely cause was
    an infection A.M. had at the time; and (3) the onset of
    A.M.’s limping was outside the medically accepted
    timeframe. 
    Id. at *17-20.
        The Miliks sought review of the special master’s deci-
    sion in the Court of Federal Claims, asserting three
    primary arguments. First, they argued that the Court of
    1   During oral argument before this court, counsel
    for the Miliks reiterated that they did not attempt to
    separate A.M.’s condition into two distinct issues. Oral
    Argument     at   19:17-20:08,   available    at   http://

    5109.mp3.
    8                                               MILIK   v. HHS
    Federal Claims is constitutionally required to conduct a
    de novo review of the special master’s decision. 
    Milik, 121 Fed. Cl. at 72
    n.11 (citing Bruesewitz v. Wyeth LLC, 
    562 U.S. 223
    (2011)). Second, the Miliks objected to the
    special master’s onset finding, and his determination that
    Dr. Kohrman was more credible and persuasive than Dr.
    Souayah. 
    Id. at 72.
    Finally, the Miliks objected to the
    special master’s alternative findings.
    In a decision dated April 29, 2015, the Court of Feder-
    al Claims sustained the special master’s decision. The
    court began by dismissing the Miliks’ constitutional
    argument regarding the applicable standard of review in
    a footnote, agreeing with the government that the Vaccine
    Act “does not bar a petitioner from later filing a claim in
    an Article III federal court, and that petitioners’ reliance
    on Bruesewitz is misplaced.” 
    Id. at 72
    n.11.
    The court then considered the Miliks’ objections to the
    special master’s onset finding that A.M.’s global develop-
    mental delay preceded his MMR vaccination. Although
    the court found that some of Dr. Kohrman’s inferences
    based on A.M.’s well-child examinations were not well-
    supported, it concluded that the special master’s decision
    “was not based solely, or even largely, on those records.”
    
    Id. at 86.
    Instead, the special master based his decision
    on a number of other records, including: (1) Dr. Maytal’s
    March 1998 diagnosis of longstanding global delay; (2) Dr.
    Malinowska’s September 1998 diagnosis of delay in
    communication, daily living skills, and motor skills;
    (3) A.M.’s parents’ repeated reports that he suffered no
    cognitive regression; and (4) Dr. Kohrman’s interpretation
    of two MRI studies of A.M.’s brain taken in 1998. 
    Id. Because the
    special master’s onset decision was based on
    reliable evidence in the record, the court concluded that it
    was not arbitrary or capricious. And, because the court
    sustained that decision, it found it unnecessary to consid-
    er the Miliks’ objection to the special master’s alternative
    findings. 
    Id. at 87.
    MILIK   v. HHS                                             9
    The Miliks timely appealed to this court, and we have
    jurisdiction pursuant to 28 U.S.C. § 1295(a)(3) and 42
    U.S.C. § 300aa-12(f).
    II. DISCUSSION
    On appeal, the Miliks argue that: (1) the Vaccine Act,
    and its attendant arbitrary and capricious standard of
    review, is unconstitutional because it deprives petitioners
    of their right to de novo review in an Article III court; and
    (2) even if the standard of review is constitutional, the
    special master’s decision denying compensation is arbi-
    trary and capricious because it is unsupported in the
    record. We address each argument in turn.
    A. Jurisdiction and Standard of Review
    “Childhood vaccinations, though an important part of
    the public health program, are not without risk.” Terran
    v. Sec’y of Health & Human Servs., 
    195 F.3d 1302
    , 1306
    (Fed. Cir. 1999). Recognizing that vaccines can cause
    serious adverse side effects in rare circumstances, “Con-
    gress became concerned that tort liability and related
    costs might drive up the prices of vaccines and discourage
    vaccine manufacturers from staying in this market, and
    that normal tort litigation might leave many sufferers of
    vaccine-caused injuries uncompensated.” 
    Id. at 1307
    (citing H.R. Rep. No. 99-908, at 1, 4, 6-7 (1986), reprinted
    in 1986 U.S.C.C.A.N. 6287, 6345, 6347-48).
    Accordingly, Congress enacted the Vaccine Act in
    1986 to increase the safety and availability of vaccines.
    
    Id. at 1307
    . The Vaccine Act created the National Vac-
    cine Injury Compensation Program (“the Program”),
    through which claimants can petition for compensation
    for vaccine-related injury or death.       See 42 U.S.C.
    § 300aa-10(a). In doing so, the Act established a no-fault
    compensation program “designed to work faster and with
    greater ease than the civil tort system.” Shalala v. White-
    cotton, 
    514 U.S. 268
    , 269 (1995). The Act requires claim-
    10                                                MILIK   v. HHS
    ants to seek relief through the Program before filing a
    civil action in a state or federal court against a vaccine
    administrator or manufacturer for damages in an amount
    greater than $1,000. 42 U.S.C. § 300aa-11(a)(2)(A).
    As originally enacted, the Vaccine Act provided the
    “district courts of the United States” jurisdiction to de-
    termine if a petitioner was entitled to compensation under
    the Program. National Childhood Vaccine Injury Act of
    1986, Pub. L. No. 99-660, § 2112(a), 100 Stat. 3743, 3761.
    The district court would designate a special master to
    prepare proposed findings of fact and conclusions of law.
    
    Id. at §
    2112(c), 100 Stat. at 3761-62. The Act provided
    that, “upon objection . . . to the proposed findings of fact or
    conclusions of law prepared by the special master or upon
    the court’s own motion, the court shall undertake a review
    of the record of the proceedings and may thereafter make
    a de novo determination of any matter and issue its
    judgment accordingly, including findings of fact and
    conclusions of law, or remand for further proceedings.”
    
    Id. at §
    2112(d)(1), 100 Stat. at 3762.
    The Vaccine Compensation Amendments of 1987
    transferred jurisdiction from “district courts of the United
    States” to “the United States Claims Court.” See Omni-
    bus Budget Reconciliation Act of 1987, Pub. L. No. 100-
    203, § 4307, 101 Stat. 1330, 1330-224 to 1330-225 (amend-
    ing 42 U.S.C. § 300aa-11). 2       Congress subsequently
    amended the Act to establish, within the United States
    Claims Court, an office of special masters to review com-
    pensation claims. See Omnibus Budget Reconciliation Act
    of 1989, Pub. L. No. 101-239, § 6601(e), 103 Stat. 2106,
    2  Congress later replaced the references to the
    “United States Claims Court” with the “United States
    Court of Federal Claims.” See Court of Federal Claims
    Technical and Procedural Improvements Act of 1992, Pub.
    L. No. 102-572, § 902, 106 Stat. 4506, 4516.
    MILIK   v. HHS                                            11
    2286-89 (amending 42 U.S.C. § 300aa-12). At the same
    time, Congress changed the standard of review. Rather
    than de novo review, the amendment provided that the
    Claims Court “shall have jurisdiction to . . . set aside any
    findings of fact or conclusion of law of the special master
    found to be arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law and issue its own
    findings of fact and conclusion of law.”              
    Id. at §
    6601(h)(2)(B), 103 Stat. at 2289-90 (codified at 42 U.S.C.
    § 300aa-12(e)(2)(B)). By statute, the Court of Federal
    Claims’ judgment may be reviewed in this court. 42
    U.S.C. § 300aa-12(f).
    We review an appeal from the Court of Federal
    Claims in a Vaccine Act case de novo, applying the same
    standard of review that court applied in reviewing the
    special master’s decision. Broekelschen v. Sec’y of Health
    & Human Servs., 
    618 F.3d 1339
    , 1345 (Fed. Cir. 2010)
    (citing Andreu v. Sec’y of Health & Human Servs., 
    569 F.3d 1367
    , 1373 (Fed. Cir. 2009)). Although we review
    legal determinations without deference, we review the
    special master’s factual findings under the arbitrary and
    capricious standard. Griglock v. Sec’y of Health & Human
    Servs., 
    687 F.3d 1371
    , 1374 (Fed. Cir. 2012); see Hines v.
    Sec. of Health & Human Servs., 
    940 F.2d 1518
    , 1524 (Fed.
    Cir. 1991) (“In effect, then, we review the underlying
    decision of the special master under the arbitrary and
    capricious standard of § 300aa-12(e)(2)(B).”).
    The arbitrary and capricious standard is “difficult for
    an appellant to satisfy with respect to any issue, but
    particularly with respect to an issue that turns on the
    weighing of evidence by the trier of fact.” Lampe v. Sec’y
    of Health & Human Servs., 
    219 F.3d 1357
    , 1360 (Fed. Cir.
    2000). If the special master “has considered the relevant
    evidence of record, drawn plausible inferences and articu-
    lated a rational basis for the decision,” then reversible
    error is “extremely difficult to demonstrate.” 
    Hines, 940 F.2d at 1528
    . As this court has recognized:
    12                                              MILIK   v. HHS
    Congress assigned to a group of specialists, the
    Special Masters within the Court of Federal
    Claims, the unenviable job of sorting through
    these painful cases and, based upon their accumu-
    lated expertise in the field, judging the merits of
    the individual claims. The statute makes clear
    that, on review, the Court of Federal Claims is not
    to second guess the Special Masters fact-intensive
    conclusions; the standard of review is uniquely
    deferential for what is essentially a judicial pro-
    cess. Our cases make clear that, on our review of
    the judgment of the Court of Federal Claims, we
    remain equally deferential. That level of defer-
    ence is especially apt in a case in which the medi-
    cal evidence of causation is in dispute.
    Hodges v. Sec’y of Health & Human Servs., 
    9 F.3d 958
    ,
    961 (Fed. Cir. 1993) (internal citations omitted). Accord-
    ingly, we “do not reweigh the factual evidence, assess
    whether the special master correctly evaluated the evi-
    dence, or examine the probative value of the evidence or
    the credibility of the witnesses – these are all matters
    within the purview of the fact finder.” Porter v. Sec’y of
    Health & Human Servs., 
    663 F.3d 1242
    , 1249 (Fed. Cir.
    2011) (citing 
    Broekelschen, 618 F.3d at 1349
    ). Rather, as
    long as the special master’s “conclusion [is] based on
    evidence in the record that [is] not wholly implausible, we
    are compelled to uphold that finding as not being arbi-
    trary or capricious.” Cedillo v. Sec’y of Health & Human
    Servs., 
    617 F.3d 1328
    , 1338 (Fed. Cir. 2010) (citation
    omitted).
    On appeal, the Miliks argue that the Vaccine Act un-
    constitutionally denies them access to de novo review in
    an Article III court. Specifically, they argue that, by
    limiting a vaccine injury claimant to filing a claim against
    the Secretary in an Article I court, “the Vaccine Act has
    deprived petitioners of the rights granted in Article III of
    the United States Constitution and the common law
    MILIK   v. HHS                                             13
    protections afforded in state courts for tortious injuries
    against the manufacturers of vaccines.” Pet’rs Br. 14-15.
    The Miliks point to two recent Supreme Court decisions
    which they argue, when taken together, support their
    argument that the Vaccine Act is unconstitutional:
    Bruesewitz v. Wyeth LLC, 
    562 U.S. 223
    (2011), and Stern
    v. Marshall, 
    564 U.S. 462
    (2011).
    In Bruesewitz, the Court held that the Vaccine Act
    “pre-empts all design-defect claims against vaccine manu-
    facturers brought by plaintiffs who seek compensation for
    injury or death caused by vaccine side 
    effects.” 562 U.S. at 243
    . There, the Court considered 42 U.S.C. § 300aa-
    22(b)(1), which provides that:
    No vaccine manufacturer shall be liable in a civil
    action for damages arising from a vaccine-related
    injury or death associated with the administration
    of a vaccine after October 1, 1988, if the injury or
    death resulted from side effects that were una-
    voidable even though the vaccine was properly
    prepared and was accompanied by proper direc-
    tions and warnings.
    Given the statutory text, the Court concluded that, as
    long as “there was proper manufacture and warning, any
    remaining side effects, including those resulting from
    design defects, are deemed to have been unavoidable.
    State-law design-defect claims are therefore preempted.”
    
    Id. at 231-32.
        The Miliks also cite the Supreme Court’s decision in
    Stern, which reiterated that:
    Congress may not “withdraw from judicial cogni-
    zance any matter which, from its nature, is the
    subject of a suit at the common law, or in equity,
    or admiralty.” Murray’s Lessee v. Hoboken Land
    & Improvement Co., 
    59 U.S. 272
    (1856). When a
    suit is made of “the stuff of the traditional actions
    14                                                MILIK   v. HHS
    at common law tried by the courts at Westminster
    in 1789,” . . . and is brought within the bounds of
    federal jurisdiction, the responsibility for deciding
    that suit rests with Article III judges in Article III
    courts.    The Constitution assigns that job—
    resolution of “the mundane as well as the glamor-
    ous, matters of common law and statute as well as
    constitutional law, issues of fact as well as issues
    of law”—to the 
    Judiciary. 564 U.S. at 484
    (citation omitted). Applying these princi-
    ples in Stern, the Court held that an Article I bankruptcy
    court “lacked the constitutional authority to enter a final
    judgment on a state law counterclaim that is not resolved
    in the process of ruling on a creditor’s proof of claim.” 
    Id. at 503.
    In reaching this conclusion, the Court noted that
    it was not dealing with “a situation in which Congress
    devised an ‘expert and inexpensive method for dealing
    with a class of questions of fact which are particularly
    suited to examination and determination by an adminis-
    trative agency specially assigned to that task.’” 
    Id. at 494
    (citation omitted). Instead, the “‘experts’ in the federal
    system at resolving common law counterclaims such as
    Vickie’s [tortious interference counterclaim] are the
    Article III courts, and it is with those courts that her
    claim must stay.” 
    Id. 3 3
     Stern was recently narrowed in Wellness Interna-
    tional Network v. Sharif, 
    135 S. Ct. 1932
    (2015). There,
    the Court made clear that “Article III is not violated when
    the parties knowingly and voluntarily consent to adjudi-
    cation by a bankruptcy judge.” 
    Id. at 1939.
    The Court
    explained that “allowing Article I adjudicators to decide
    claims submitted to them by consent does not offend the
    separation of powers so long as Article III courts retain
    supervisory authority over the process.” 
    Id. at 1944.
    MILIK   v. HHS                                           15
    The Miliks’ briefing on Stern is sparse, and the gov-
    ernment’s response does not address it. At oral argu-
    ment, counsel for the Miliks clarified their position as
    follows:
    Under the original understanding of the Act, there
    was an opportunity for a petitioner to reject the
    judgment in the Vaccine court or elect to proceed
    in a state or federal court under common law or
    under state statutes. That is now gone. We sub-
    mit that a litigant bringing these kinds of claims
    is entitled to de novo review in an Article III
    court, as it traditionally would be available.
    Oral Argument at 3:02-3:37, available at http://
    oralarguments.cafc.uscourts.gov/default.aspx?fl=2015-
    5109.mp3. The Miliks suggest that, in light of Stern—
    which says that, unless certain exceptions apply, Con-
    gress cannot take away access to Article III courts for
    resolution of common law claims—the Supreme Court’s
    decision in Bruesewitz rendered the Vaccine Act unconsti-
    tutional because it does just that. We disagree.
    The separation of powers concerns at play in Stern
    are not implicated by Bruesewitz. In the Vaccine context,
    the only questions the special master addresses are those
    related to the fact of injury and causation. No liability
    issues are determined by the special master; it is a no
    fault statute that assumes the right to recovery whenever
    injury and causation are established. The “design defect”
    question is never addressed by the Article I court or its
    special master program.
    The issues that are addressed are not barred from
    subsequent Article III review. While the legal theories
    under which questions of injury and causation may be
    reconsidered by the Article III court may be narrowed by
    Bruesewitz’s reading of the Vaccine Act, those questions
    nonetheless can be revisited. Indeed, the Miliks could
    revisit the very issues decided by the special master in the
    16                                              MILIK   v. HHS
    context of a manufacturing defect claim, breach of express
    or implied warranty claims, or even a contract claim if the
    predicate for such claims exists. Thus, even if Stern were
    applicable to these facts, its limitations would not be
    violated.
    More importantly, however, is the fact that Stern is
    not applicable here. The only constitutional question
    Bruesewitz implicates is whether Congress may preempt a
    cause of action altogether, such that no court may decide
    the claim. There is no doubt Congress has the authority
    under the Supremacy Clause to preempt state law causes
    of action which conflict with the federal standards and
    policies set forth in a duly authorized federal statute. See
    Lorillard Tobacco Co. v. Reilly, 
    533 U.S. 525
    , 541 (2001)
    (“State action may be foreclosed by express language in a
    congressional enactment, by implication from the depth
    and breadth of a congressional scheme that occupies the
    legislative field, or by implication because of a conflict
    with a congressional enactment.” (internal citations
    omitted)). That is precisely what the Court in Bruesewitz
    said Congress did when it passed the Vaccine Act. See
    
    Bruesewitz, 562 U.S. at 231-33
    . We have no authority to
    disagree with that conclusion, and do not believe Stern
    provides a vehicle for doing so. Stern simply does not
    address the preemption of state law claims; it only ad-
    dresses who may decide claims that are not otherwise
    preempted.
    Because the Court’s decision in Stern does not apply
    in these circumstances, and because the Court’s decision
    in Bruesewitz has no bearing on the applicable standard
    of review, we continue to review the special master’s
    findings of fact under the deferential arbitrary and capri-
    cious standard.
    MILIK   v. HHS                                            17
    B. The Special Master’s Decision Was
    Neither Arbitrary Nor Capricious
    A petitioner seeking compensation under the Vaccine
    Act must show, by a preponderance of the evidence, “that
    the injury or death at issue was caused by a vaccine.”
    
    Broekelschen, 618 F.3d at 1341
    (citing 42 U.S.C. §§ 300aa-
    11(c)(1), -13(a)(1)). A petitioner can establish causation in
    one of two ways. 
    Id. If the
    petitioner shows that he or
    she received a vaccination listed on the Vaccine Injury
    Table, 42 U.S.C. § 300aa-14, and suffered an injury listed
    on that table within a statutorily prescribed time period,
    then the Act presumes the vaccination caused the injury.
    Andreu v. Sec’y of Health & Human Servs., 
    569 F.3d 1367
    ,
    1374 (Fed. Cir. 2009). Where, as here, the injury is not on
    the Vaccine Injury Table, the petitioner may seek com-
    pensation by proving causation-in-fact. 
    Id. To prove
    causation, a petitioner must show that the
    vaccine was “not only a but-for cause of the injury but also
    a substantial factor in bringing about the injury.” Shyface
    v. Sec’y of Health & Human Servs., 
    165 F.3d 1344
    , 1352
    (Fed. Cir. 1999). Specifically, the petitioner must show
    the following by a preponderance of the evidence: (1) a
    medical theory causally connecting the vaccination to the
    injury; (2) a logical sequence of cause and effect demon-
    strating that the vaccination caused the injury; and (3) a
    proximate temporal relationship between the vaccine and
    the injury. Althen v. Sec’y of Health & Human Servs., 
    418 F.3d 1274
    , 1278 (Fed. Cir. 2005). If the petitioner satis-
    fies this burden, he is “entitled to compensation unless
    the government can show by a preponderance of the
    evidence that the injury is due to factors unrelated to the
    vaccine.” 
    Broekelschen, 618 F.3d at 1341
    (citing Doe v.
    Sec’y of Health & Human Servs., 
    601 F.3d 1349
    , 1351
    (Fed. Cir. 2010)).
    The special master found that the Miliks met their
    burden of establishing the first prong of the Althen test,
    18                                              MILIK   v. HHS
    but failed to meet prongs two and three. Indeed, as to the
    first prong, both parties’ experts agreed that the MMR
    vaccination is capable of causing an encephalitis or en-
    cephalopathy.      Special Master Decision, 
    2014 WL 6488735
    , at *28. As to prong two, the special master
    found that the Miliks failed to show that the MMR vac-
    cine caused A.M.’s condition because the record evidence
    revealed that A.M. had a preexisting developmental
    delay. 
    Id. 4 Although
    the special master deemed it unnec-
    essary to address the third Althen prong, given his finding
    that the Miliks did not satisfy the second, he nonetheless
    found that A.M.’s condition did not fit the timeframe
    discussed in the medical literature of record, thus preclud-
    ing a finding of a proximate temporal relationship be-
    tween the vaccine and injury. 
    Id. On appeal,
    the Miliks allege that there was “no credi-
    ble evidence supporting the special master’s finding that
    A.M. had a developmental disorder preceding the admin-
    istration of the MMR vaccination.” Pet’rs Br. 11. Specifi-
    cally, they argue that the special master erred in:
    (1) determining that the onset of A.M.’s condition predat-
    ed the vaccine; (2) rejecting Dr. Maytal’s clarification of
    the term “longstanding”; and (3) crediting Dr. Kohrman’s
    opinion over that of Dr. Souayah. As to the alternative
    findings, the Miliks contend that the special master erred
    in finding that they failed to show a medically appropriate
    temporal relationship between A.M.’s condition and the
    MMR vaccine.
    The Miliks’ essentially ask this court to reweigh the
    factual evidence and assess the credibility of the witness-
    es. As an appellate tribunal, we can do neither. See
    4  The special master clarified that the Miliks “failed
    to show that A.M.’s condition was either initially caused
    by his vaccinations, or was aggravated in any way by his
    vaccinations.” 
    Id. at *28
    n.31.
    MILIK   v. HHS                                          19
    
    Porter, 663 F.3d at 1249
    . And, as explained below, be-
    cause the special master’s onset decision was based on
    reliable evidence of record, it was neither arbitrary nor
    capricious.
    First, the Miliks argue that the contemporaneous
    medical records reveal that A.M.’s pre-vaccination devel-
    opment was normal, and that none of his treating physi-
    cians noted any developmental delay. The Miliks further
    note that the Court of Federal Claims found “multiple
    instances where the record failed to support the special
    master’s findings” with respect to A.M.’s pre-vaccination
    development. Pet’rs Br. 17.
    While it is true that the court found some of Dr.
    Kohrman’s inferences unsupported, the special master
    considered all of the evidence of record and relied sub-
    stantially on one of the first contemporaneous medical
    records created: Dr. Maytal’s diagnosis that A.M. suffered
    from “longstanding” global developmental delay. See
    Special Master Decision, 
    2014 WL 6488735
    , at *10. The
    special master also relied on records from A.M.’s bilingual
    psychologist—Dr. Malinowska—showing that, at age four
    years and nine months, A.M. was delayed in his commu-
    nication, daily living, and motor skills. 
    Id. at *14.
    These
    reports, coupled with the Miliks’ own representation that
    A.M. did not experience cognitive regression post-
    vaccination, supported the inference that A.M.’s develop-
    mental delay must have preceded the vaccination. 
    Id. The special
    master further considered two of A.M.’s
    post-vaccination MRI studies conducted in 1998, both of
    which showed no interval changes. 
    Id. at *15.
    Dr.
    Kohrman opined that those studies were “consistent with
    a demyelinating or dysmyelinating process that produced
    longstanding developmental delay dating back to his
    examination at the age of two years.” 
    Id. In light
    of the
    foregoing, we agree with the Court of Federal Claims that
    “the special master based his finding that the onset of
    20                                              MILIK   v. HHS
    A.M.’s global developmental delay preceded his MMR
    vaccination on reliable evidence in the record.” 
    Milik, 121 Fed. Cl. at 86
    .
    Next, the Miliks argue that the special master unfair-
    ly rejected as “litigation driven” Dr. Maytal’s letter clari-
    fying his use of the term “longstanding.” As noted, in
    March 1998, Dr. Maytal examined A.M. and identified
    two issues: “longstanding” global delay and “acute” symp-
    toms of limping. Roughly sixteen years later, Dr. Maytal
    sent a letter stating that the “term ‘longstanding’ should
    be interpreted as ‘a condition existing prior to examina-
    tion.’ We are unable to determine the time length of
    symptoms.” Special Master Decision, 
    2014 WL 6488735
    ,
    at *12.
    Recognizing that Dr. Maytal’s letter was “not contem-
    poraneous to the events to which it sp[oke],” and was
    “outside the context of diagnosis and treatment,” the
    special master found that it was “entitled to less defer-
    ence.” 
    Id. at *12
    n.14. Although the special master
    classified Dr. Maytal’s letter as “litigation driven,” he did
    not reject it for that reason. Instead, the special master
    “found that the meaning of longstanding urged by peti-
    tioners simply did not make sense within the context of
    Dr. Maytal’s original diagnosis.” 
    Milik, 121 Fed. Cl. at 82
    .
    The special master began by looking to the dictionary
    definition of “longstanding,” which is “of long duration.”
    Special Master Decision, 
    2014 WL 6488735
    , at *12 n.15.
    He then noted that Dr. Maytal performed his initial
    examination only one month after A.M. received the MMR
    vaccination. The special master found that the “ordinary
    use of the term ‘longstanding’ would indicate that the
    delay had lasted substantially longer than one month.”
    
    Id. at *12.
    Next, the special master found it significant
    that Dr. Maytal’s original report contrasted A.M.’s
    “longstanding” delay with his “acute” onset of limping,
    which began ten days prior to the examination. To accept
    MILIK   v. HHS                                           21
    Dr. Maytal’s clarification of “longstanding” to mean “a
    condition existing prior to the examination,” would “erase
    the distinction he originally drew between the ‘longstand-
    ing’ global delay and the ‘acute’ symptom of limping, and
    would make the original record incoherent as written.”
    
    Id. On this
    record, we conclude that the special master
    reasonably chose to credit the plain meaning of
    “longstanding” over Dr. Maytal’s belated clarification.
    Finally, the Miliks argue that the special master
    erred in finding Dr. Kohrman, the government’s expert,
    more persuasive than Dr. Souayah. It is well established
    that “[f]inders of fact are entitled—indeed, expected—to
    make determinations as to the reliability of the evidence
    presented to them and, if appropriate, as to the credibility
    of the persons presenting that evidence.” Moberly v. Sec’y
    of Health & Human Servs., 
    592 F.3d 1315
    , 1326 (Fed. Cir.
    2010). We have recognized that “special masters have
    that responsibility in Vaccine Act cases.” 
    Id. at 1325.
    We
    have further recognized that a “special master’s decision
    often times is based on the credibility of the experts and
    the relative persuasiveness of their competing theories,”
    and that the special master’s credibility findings “‘are
    virtually unchallengeable on appeal.’” 
    Broekelschen, 618 F.3d at 1347
    (quoting 
    Lampe, 219 F.3d at 1361
    ).
    The record reveals that the special master considered
    the conflicting testimony from the parties’ experts and
    reasonably concluded that Dr. Kohrman’s opinion was
    entitled to more weight. To begin, the special master
    found that Dr. Souayah’s testimony was based on a
    “flawed assumption as to the time of onset of A.M.’s
    neurological dysfunction.” Special Master Decision, 
    2014 WL 6488735
    , at *16. The special master also found that
    Dr. Kohrman was more qualified to address the issues in
    this case, given that he is a pediatric neurologist who sees
    children with neurological problems on a regular basis.
    In contrast, Dr. Souayah generally treats adults and “has
    22                                            MILIK   v. HHS
    not diagnosed developmental delay in a child since his
    residency in 2002.” 
    Id. The special
    master further found Dr. Kohrman more
    persuasive because his testimony evinced a more detailed
    understanding of the Denver Developmental Screening
    Test (“the Denver test”), which Dr. Maytal applied in his
    examination of A.M. 
    Id. at *11-12.
    Dr. Kohrman ex-
    plained that failing one of the Denver test’s language
    domains is cause for concern, and that “Dr. Maytal noted
    that A.M. failed three language domains—A.M. could not
    use plurals, could not use his last name, and failed to
    comprehend cold.” 
    Id. at *12.
    While Dr. Kohrman ana-
    lyzed A.M.’s scoring under the Denver criteria, Dr.
    Souayah “did not touch on any of the specifics of the
    Denver test.” 
    Id. We find
    nothing arbitrary or capricious
    about the special master’s determination that Dr.
    Kohrman’s testimony was more persuasive than that of
    Dr. Souayah. See Locane v. Sec’y of Health & Human
    Servs., 
    685 F.3d 1375
    , 1379-80 (Fed. Cir. 2012) (finding
    “nothing arbitrary or capricious” about the special mas-
    ter’s decision to credit the government expert’s testimony
    regarding the onset of injury).
    This case, like so many in the Vaccine Act context,
    turns on its facts. While we agree with the Court of
    Federal Claims that some of the inferences Dr. Kohrman
    drew from A.M.’s pre-vaccination records were unsup-
    ported, we also agree that the special master’s decision
    “was not based solely, or even largely, on those records.”
    
    Milik, 121 Fed. Cl. at 86
    . We conclude that the special
    master thoroughly reviewed all of the relevant evidence,
    including the expert witnesses’ testimonies and reports,
    and that the record supports his finding that A.M.’s
    developmental delay predated the MMR vaccination. We
    therefore cannot say that the special master’s onset
    decision was arbitrary or capricious. Because the Miliks
    failed to show that the MMR vaccination caused A.M.’s
    injury, they did not meet their burden under the second
    MILIK   v. HHS                                           23
    Althen prong, and the special master correctly denied the
    petition for compensation. Given this conclusion, we need
    not address the special master’s alternative findings.
    III. CONCLUSION
    While we certainly sympathize with the Milik family,
    we conclude that the special master’s decision was not
    “arbitrary, capricious, an abuse of discretion, or otherwise
    not in accordance with law.”           42 U.S.C. § 300aa-
    12(e)(2)(B). For the foregoing reasons, and because we
    find the Miliks’ remaining arguments unpersuasive, we
    affirm the judgment of the Court of Federal Claims.
