    Opinion
    McDONALD, J. Congress created the National Prac-
    titioner Data Bank (Practitioner Data Bank) and the
    Healthcare Integrity and Protection Data Bank (Health-
    care Data Bank) as national clearinghouses for, inter
    alia, information from health care entities and licensing
    boards regarding adverse actions taken against physi-
    cians and other licensed health care practitioners. The
    question we must answer in the present case is whether
    records received from these federal data banks by a
    state agency authorized to request this confidential
    information can be subject to disclosure under our Free-
    dom of Information Act (act), General Statutes § 1-200
    et seq.
    The named defendant, the Freedom of Information
    Commission (commission), concluded that federal law
    permits disclosure of Practitioner Data Bank records
    if they are subject to disclosure under state law such
    as the act, but does not permit disclosure of Healthcare
    Data Bank records. The trial court dismissed the appeal
    of the plaintiff, the Commissioner of Public Health
    (department),1 from the commission’s decision order-
    ing the department to disclose Practitioner Data Bank
    records to a local newspaper, the defendant Greenwich
    Time (newspaper). The trial court also dismissed the
    newspaper’s appeal from the commission’s decision
    insofar as it had denied the newspaper’s request for an
    order to disclose the Healthcare Data Bank records.
    The department appealed and the newspaper cross
    appealed from the trial court’s judgment. We conclude
    that a public agency may not disclose to an unautho-
    rized person or entity any records received from either
    the Practitioner Data Bank or the Healthcare Data Bank,
    although the agency may disclose to a member of the
    public information originating from the agency’s own
    files if disclosure is otherwise required under the act.
    Accordingly, we reverse the trial court’s judgment with
    respect to the department’s appeal.
    The record reveals the following undisputed facts. In
    August, 2005, a married couple, proceeding as Jane
    Smith and John Smith, filed an action against Ben Rama-
    ley, a Greenwich obstetrician/gynecologist from whom
    the couple had obtained an intrauterine insemination
    procedure. They alleged that DNA tests of the twin girls
    born as a result of that procedure proved that Ramaley
    had inseminated Jane Smith with the sperm of someone
    other than her husband. The complaint further alleged,
    upon information and belief, that Ramaley intentionally
    inseminated Jane Smith with his own sperm. Before
    discovery was completed, the case was settled and the
    records were sealed.
    In January, 2007, the department, which had issued
    Ramaley’s license to practice as a physician and surgeon
    in Connecticut, received notification from the Prac-
    titioner Data Bank of the settlement of a malpractice
    action against Ramaley. See 42 U.S.C. § 11134 (c) (1)
    (2006). The department initiated an investigation and
    brought in a consultant from the American Board of
    Obstetrics and Gynecology, Robert J. Gfeller, to review
    Ramaley’s conduct in connection with the case. In Octo-
    ber, 2007, Gfeller issued a report finding gross violations
    of the standard of care by Ramaley, but no such viola-
    tion with respect to the specific allegation that Ramaley
    had used his own sperm in the insemination procedure
    due to the absence of a DNA test that would give credi-
    ble, positive evidence of that fact. Thereafter, the
    department and Ramaley entered into a consent order,
    designated as a public document, under which Ramaley
    did not contest the department’s allegation that he had
    inseminated a patient with the wrong man’s sperm, but
    also did not admit any wrongdoing or guilt. The order
    indicated that Ramaley no longer performed intrauter-
    ine insemination and that he had agreed to a reprimand
    on his license and a civil penalty of $10,000.
    The newspaper learned of the department’s response
    to the allegations against Ramaley, and in November,
    2009, it sent a letter to the department making a request
    under the act for all records reviewed by Gfeller in
    connection with his report, including exhibit A, identi-
    fied in the report as ‘‘National Practitioner Data Bank.’’
    After the department complied with the request in part
    but failed to produce, inter alia, exhibit A, the newspa-
    per filed a complaint with the commission.2 At a hearing
    before the commission, the department argued that
    exhibit A contained both Practitioner Data Bank and
    Healthcare Data Bank records and that federal law pro-
    vided a basis to withhold these records. The commis-
    sion concluded that federal regulations barred
    disclosure of records received from the Healthcare Data
    Bank, but that other regulations pertaining to the Prac-
    titioner Data Bank did not bar disclosure of records
    received from that data bank.
    The department and the newspaper both appealed
    from the commission’s decision to the Superior Court,
    which thereafter affirmed the decision and rendered
    judgment dismissing the appeals. The trial court deter-
    mined that the department was required to disclose
    records that it had received from the Practitioner Data
    Bank under this court’s decision in Director of Health
    Affairs Policy Planning v. Freedom of Information
    Commission, 
    293 Conn. 164
    , 180 n.13, 
    977 A.2d 148
    (2009), but that different regulatory language
    addressing Healthcare Data Bank records that was not
    considered in that case precluded disclosure of those
    records. Appeals by both parties followed.3 Thereafter,
    we granted permission to the United States of America
    to participate as amicus curiae.
    On appeal, the department and the newspaper agree
    that the federal regulations governing confidentiality
    of Practitioner Data Bank and Healthcare Data Bank
    records should be construed to have the same effect,
    despite certain textual differences, but disagree as to
    the proper construction. The commission, which had
    taken the position in its decision that these textual
    differences compelled different treatment, represented
    at oral argument before this court that its position has
    changed in light of a recent amendment to the governing
    regulations brought to its attention by the amicus curiae
    that makes clear that records from both data banks
    are not subject to disclosure. The commission further
    contends that this amendment is clarifying and, there-
    fore, should be applied as the governing interpretation
    in the present case. The amicus contends in its brief
    that the statutes and implementing regulations of the
    United States Department of Health and Human Ser-
    vices (federal agency) always have precluded disclo-
    sure of records received from both data banks, and that
    the recent amendments merely clarify the regulations
    at issue. We conclude that any ambiguities in the regula-
    tory scheme have been dispelled by the clarifying
    amendment, under which the records are not subject
    to public disclosure under the act.
    Because the present case requires interpretation of
    federal statutes and regulations, we must interpret this
    scheme in accordance with federal law.4 See Commis-
    sioner of Correction v. Freedom of Information Com-
    mission, 
    307 Conn. 53
    , 65–66, 
    52 A.3d 636
    (2012); Bell
    Atlantic Mobile, Inc. v. Dept. of Public Utility Control,
    
    253 Conn. 453
    , 470–71, 
    754 A.2d 128
    (2000). Under fed-
    eral law, ‘‘congressional enactments and administrative
    rules will not be construed to have retroactive effect
    unless their language requires this result. . . . This pre-
    sumption . . . applies to every statute, which takes
    away or impairs vested rights acquired under existing
    laws, or creates a new obligation, imposes a new duty,
    or attaches a new disability in respect to transactions
    or considerations already past . . . . Notwithstanding
    this presumption, several Courts of Appeals have held
    that when an amendment merely clarifies existing law,
    rather than effecting a substantive change to the law,
    then retroactivity concerns do not come into play.’’

    ous . . . (2) whether the new regulation resolved, or
    at least attempted to resolve, that ambiguity . . . (3)
    whether the new regulation’s resolution of the ambigu-
    ity is consistent with the text of the old regulation . . .
    and (4) whether the new regulation’s resolution of the
    ambiguity is consistent with the agency’s prior treat-
    ment of the issue . . . .’’ (Citations omitted.)

    body declared that it was clarifying prior enactment;
    [2] whether conflict or ambiguity existed prior to
    amendment; and [3] whether amendment is consistent
    with reasonable interpretation of prior enactment and
    its legislative history). The fact that ‘‘an amendment
    alters, even significantly alters, the original statutory
    language . . . does not necessarily indicate that the
    amendment institutes a change in the law.’’ (Internal
    quotation marks omitted.) Brown v. Thompson, 
    374 F.3d 253
    , 259 (4th Cir. 2004). Rather, the court will apply
    the relevant factors to determine whether the enacting
    body merely ‘‘[made] what was intended all along even
    more unmistakably clear.’’ (Internal quotation marks
    omitted.) 
    Id. With this
    framework in mind, we turn first to the
    statutory and regulatory scheme in effect when the
    newspaper made its request for disclosure in Novem-
    ber, 2009. The Health Care Quality Improvement Act of
    1986 (1986 federal act),5 which created the Practitioner
    Data Bank, was enacted to improve health care and
    address increasing medical malpractice that warranted
    greater efforts than those that could be undertaken by
    individual states. 42 U.S.C. § 11101 (1) (2006). The 1986
    federal act: (1) encouraged effective professional peer
    review of physicians and licensed health care providers
    by providing immunity from liability under federal law
    for participants engaging in good faith review; 42 U.S.C.
    §§ 11101 and 11111 (2006); and (2) created a national
    database for information about adverse actions against
    such health care providers. Such adverse actions, which
    are required to be reported, include medical malprac-
    tice payments, sanctions from licensing boards, and
    certain professional review actions. See 42 U.S.C.
    §§ 11131 through 11133 (2006). State licensing boards,
    insurance companies making payments under a policy
    of insurance, hospitals and other health care entities are
    required to provide this information. 42 U.S.C. §§ 11131
    through 11133 (2006). In turn, these health care entities
    are authorized, and in some cases have a duty, to request
    this information. 42 U.S.C. §§ 11135 and 11137 (a)
    (2006).
    With respect to the use of information in the Prac-
    titioner Data Bank, the 1986 federal act provides in
    relevant part: ‘‘Information reported under this sub-
    chapter is considered confidential and shall not be dis-
    closed (other than to the physician or practitioner
    involved) except with respect to professional review
    activity . . . or in accordance with regulations of the
    Secretary [of Health and Human Services (secretary)
    permitting disclosure for employment related deci-
    sions]. Nothing in this subsection shall prevent the
    disclosure of such information by a party which is
    otherwise authorized, under applicable State law, to
    make such disclosure. . . .’’ (Emphasis added.) 42
    U.S.C. § 11137 (b) (1) (2006). The implementing regula-
    tion in turn provided: ‘‘Information reported to the
    [Practitioner Data Bank] is considered confidential and
    shall not be disclosed outside the [federal agency],
    except as specified in § 60.10, § 60.11 and § 60.14 [of
    title 45 of the Code of Federal Regulations]. Persons
    and entities which receive information from the [Prac-
    titioner Data Bank] either directly or from another
    party must use it solely with respect to the purpose
    for which it was provided. Nothing in this paragraph
    shall prevent the disclosure of information by a party
    which is authorized under applicable State law to
    make such disclosure.’’ (Emphasis added.) 45 C.F.R.
    § 60.13 (a) (2009).
    Several years after it created the Practitioner Data
    Bank, Congress enacted the Health Insurance Portabil-
    ity and Accountability Act of 1996 (1996 federal act),6
    in which it authorized the creation of the Healthcare
    Data Bank—‘‘a national health care fraud and abuse
    data collection program for the reporting of final
    adverse actions (not including settlements in which no
    findings of liability have been made) against health care
    providers, suppliers, or practitioners . . . .’’ 42 U.S.C.
    § 1320a-7e (a) (2006). Information in the Healthcare
    Data Bank is available to federal and state government
    agencies and health plans. 42 U.S.C. § 1320-7e (d) (1)
    (2006). There is ample evidence that the Healthcare
    Data Bank and the Practitioner Data Bank are comple-
    mentary to each other. For example, adverse actions
    reported to the Healthcare Data Bank include some of
    the same information reported to the Practitioner Data
    Bank, such as licensure actions, as well as additional
    similar information. See 42 U.S.C. § 1320a-7e (b) (1)
    and (g) (1) (2006) (requiring reporting of, inter alia,
    civil judgments other than malpractice claims, criminal
    convictions, exclusion from participation in federal or
    state health care programs and actions by state and
    federal agencies responsible for licensing and certifica-
    tion decisions). Moreover, in implementing the Health-
    care Data Bank, the secretary is directed to do so in a
    manner that avoids duplication of the reporting require-
    ments of the Practitioner Data Bank under the 1986
    federal act. 42 U.S.C. § 1320a-7e (f) (2006).
    With respect to the confidentiality of Healthcare Data
    Bank records, the 1996 federal act provides no specific
    parameters but instead authorizes the secretary and the
    United States Attorney General to issue guidelines to
    carry out the program; 42 U.S.C. § 1320a-7c (a) (3) (A)
    (2006); including ‘‘procedures to assure that such infor-
    mation is provided and utilized in a manner that appro-
    priately protects the confidentiality of the information
    and the privacy of individuals receiving health care
    services and items.’’ 42 U.S.C. § 1320a-7c (a) (3) (B) (ii)
    (2006). The implementing regulation in turn provided:
    ‘‘Information reported to the [Healthcare Data Bank] is
    considered confidential and will not be disclosed out-
    side the [federal agency], except as specified in [45
    C.F.R.] §§ 61.12 and 61.15. Persons and entities receiv-
    ing information from the [Healthcare Data Bank],
    either directly or from another party, must use it solely
    with respect to the purpose for which it was provided.
    Nothing in this section will prevent the disclosure of
    information by a party from its own files used to create
    such reports where disclosure is otherwise authorized
    under applicable State or Federal law.’’ (Emphasis
    added.) 45 C.F.R. § 61.14 (2009).
    A comparison of those sections of the Practitioner
    Data Bank and Healthcare Data Bank regulations that
    provide an exception to the circumscribed limits to
    disclosure reveals a clear textual difference. Whereas
    the Healthcare Data Bank regulation provides that
    ‘‘[n]othing in this section will prevent the disclosure of
    information by a party from its own files used to create
    such reports where disclosure is otherwise authorized
    under applicable State or Federal law’’; (emphasis
    added) 45 C.F.R. § 61.14 (2009); the Practitioner Data
    Bank regulation contains no such language. Cf. 45
    C.F.R. § 60.13 (a) (2009) (‘‘[n]othing in this paragraph
    shall prevent the disclosure of information by a party
    which is authorized under applicable State law to make
    such disclosure’’). If we were to view the Healthcare
    Data Bank regulation in isolation, we undoubtedly
    would be compelled to conclude that the commission
    could not order a public agency to disclose information
    received from the Healthcare Data Bank but could only
    order disclosure of information from the agency’s own
    files that had been provided to the Healthcare Data
    Bank. Review of the Practitioner Data Bank regulation
    in isolation might yield a different conclusion because
    of the absence of the phrase ‘‘from its own files used
    to create such reports.’’ Indeed, this court reached pre-
    cisely that conclusion in Director of Health Affairs
    Policy Planning v. Freedom of Information Commis-
    
    sion, supra
    , 
    293 Conn. 180
    n.13 (summarily concluding,
    in reliance on last sentence of 45 C.F.R. § 60.13 [a], that,
    because disclosure was authorized under act, disclo-
    sure was permitted under regulation).
    There is persuasive evidence, however, that despite
    this textual difference, the regulations were intended
    to be construed consistently. As we previously have
    explained, some of the same information collected in
    the Healthcare Data Bank also is provided to the Prac-
    titioner Data Bank. It would be incongruous to conclude
    that information in Healthcare Data Bank records is
    not subject to disclosure yet that same information is
    subject to disclosure once provided to the Practitioner
    Data Bank. There did not appear to be any mechanism
    to segregate these records to avoid this problem. See
    45 C.F.R. § 61.1 (b) (2009) (noting that ‘‘[the federal
    agency’s] consolidated reporting mechanism . . . will
    sort the appropriate actions into the [Healthcare Data
    Bank], [the Practitioner Data Bank], or both’’ [empha-
    sis added]).
    In order to construe the regulations consistently,
    however, we would need to either treat as superfluous
    the language in the Healthcare Data Bank regulation
    referring to records created from a party’s own files
    or engraft such language as a judicial gloss onto the
    Practitioner Data Bank regulation. Although the former
    approach would yield a result consistent with this
    court’s conclusion in Director of Health Affairs Policy
    Planning,7 there are strong indications that the latter
    is consistent with the intent of Congress and the federal
    agency implementing the federal acts. First, precluding
    public disclosure would be consistent with the require-
    ment barring an entity from using information received
    from the data banks for any purpose other than the one
    for which the records were provided. 45 C.F.R. §§ 60.13
    (a) and 61.14 (2009). Indeed, a regulation providing for
    a civil penalty against persons who improperly disclose,
    use or permit access to information reported in accor-
    dance with the scheme, provides: ‘‘The disclosure of
    information reported in accordance with part B of title
    IV in response to a subpoena or a discovery request is
    considered to be an improper disclosure in violation of
    [42 U.S.C. § 11137]. However, disclosure or release by
    an entity of original documents or underlying records
    from which the reported information is obtained or
    derived is not considered to be an improper disclosure
    in violation of [42 U.S.C. § 11137].’’ (Emphasis added.)
    42 C.F.R. § 1003.102 (b) (6) (2009). Thus, the regulation
    indicates a distinction between the sources of the infor-
    mation as determinative of whether disclosure is per-
    missible. Second, in the statute addressing disclosure
    of Practitioner Data Bank records, it first addresses
    limits on disclosure of information ‘‘reported’’ to the
    Practitioner Data Bank and then provides in the sen-
    tence that immediately follows: ‘‘Nothing in this subsec-
    tion shall prevent the disclosure of such information by
    a party which is otherwise authorized, under applicable
    State law, to make such disclosure.’’ (Emphasis added.)
    42 U.S.C. § 11137 (b) (1) (2006). When read in context,
    ‘‘such information’’ appears to refer to information
    reported to the Practitioner Data Bank, meaning from
    the party’s own files.8 Third, this construction is consis-
    tent with the one publicly articulated by the implement-
    ing federal agency since 2001. See U.S. Dept. of Health
    and Human Services, Health Resources and Services
    Administration, ‘‘National Practitioner Data Bank
    Guidebook,’’ (September 2001) pp. A-4 and A-5, avail-
    able at http://www.ire.org/media/uploads/files/datali-
    brary/npdb/guidebook.pdf (last visited March 12, 2014).
    Finally, we note that this construction would avoid the
    anomaly of permitting public disclosure of information
    submitted to the data banks from a state whose law
    would bar public disclosure of that information.
    Whatever ambiguity might have remained has been
    dispelled by the recent amendments to the governing
    scheme. Under § 6403 of the Patient Protection and
    Affordable Care Act of 2010, Pub. L. No. 111-148, 124
    Stat. 763, ‘‘the Secretary [is required] to establish a
    transition period to transfer all data in the [Healthcare
    Data Bank] to the [Practitioner Data Bank], and, once
    completed, to cease operations of the [Healthcare Data
    Bank]. Information previously collected and disclosed
    to eligible parties through the [Healthcare Data Bank]
    will then be collected and disclosed to eligible parties
    through the [Practitioner Data Bank].’’ 78 Fed. Reg.
    20,473; see also 
    id., 20,474 (‘‘[§]
    6403 . . . eliminate[s]
    duplication between the [Healthcare Data Bank] and
    the [Practitioner Data Bank]’’). The new regulation,
    effective May 6, 2013, prescribes limitations on the dis-
    closure of data bank information following this consoli-
    dation: ‘‘Information reported to the [Practitioner Data
    Bank] is considered confidential and shall not be dis-
    closed outside the [federal agency], except as specified
    in §§ 60.17, 60.18, and 60.21 of this part. Persons and
    entities receiving information from the [Practitioner
    Data Bank], either directly or from another party, must
    use it solely with respect to the purpose for which
    it was provided. The Data Bank report may not be
    disclosed, but nothing in this section will prevent the
    disclosure of information by a party from its own files
    used to create such reports where disclosure is other-
    wise authorized under applicable state or Federal law.’’
    (Emphasis added.) 45 C.F.R. § 60.20 (a) (2013). Thus,
    there is no question that, under current law, the newspa-
    per would not be entitled to either Practitioner Data
    Bank records or Healthcare Data Bank records, but
    nonetheless could receive information subject to disclo-
    sure under the act that the department had obtained
    independently from other sources in its own files.
    Notably, the federal agency, in response to a com-
    ment on the final rules requesting clarification as to
    whether Practitioner Data Bank records would be sub-
    ject to disclosure under a state freedom of information
    act, explained that the new regulations did not change
    the current disclosure limitations, that the change from
    the existing Practitioner Data Bank regulation was
    ‘‘clarifying language,’’9 and that disclosure would not
    be permitted under such acts except as to information
    from a party’s own files that had been used to create
    the report. See 78 Fed. Reg. 20,473, 20,483;10 see also
    
    id. (explaining in
    ‘‘Summary of Revisions in the Final
    Rule’’ that federal agency had ‘‘modified language in
    this section to clarify that a Data Bank report itself
    may not be disclosed, except as permitted by [45 C.F.R.]
    §§ 60.17, 60.18, and 60.21 [2013]’’ [emphasis added]); 77
    Fed. Reg. 9138, 9149 (The federal agency, in its notice
    of the proposed rule, explained: ‘‘We propose to slightly
    amend redesignated [45 C.F.R.] § 60.20 so that it reflects
    the limitations on disclosure provisions based on cur-
    rent [Practitioner Data Bank] and [Healthcare Data
    Bank] regulatory language. These confidentiality
    requirements would apply to all information obtained
    from the [Practitioner Data Bank].’’ [Emphasis added.]).
    We conclude that the federal statutory and regulatory
    schemes in effect when the newspaper made its request
    strongly suggest that records received from both the
    Practitioner Data Bank and the Healthcare Data Bank
    would not be subject to disclosure under the act. We
    further conclude that this interpretation is confirmed
    by the subsequent, clarifying enactments. See Erlen-
    baugh v. United States, 
    409 U.S. 239
    , 243–44, 
    93 S. Ct. 477
    , 
    34 L. Ed. 2d 446
    (1972) (‘‘a later act can . . . be
    regarded as a legislative interpretation of [an] earlier
    act . . . in the sense that it aids in ascertaining the
    meaning of the words as used in their contemporary
    setting, and is therefore entitled to great weight in
    resolving any ambiguities and doubts’’ [internal quota-
    tion marks omitted]). Contrary to the newspaper’s sug-
    gestion, we do not find it significant that the amended
    regulation, 45 C.F.R. § 60.20 (2013), was made effective
    on May 6, 2013. This regulation was adopted in connec-
    tion with the consolidation of the two data banks, for
    which it was necessary to provide a transition period.
    In addition, the new regulation simply confirms the
    most reasonable interpretation of the existing schemes.
    Finally, we note that the clarifying language is not, as
    a substantive matter, applied retroactively because the
    clarification simply makes clear what the law meant
    all along. See Commissioner of Internal Revenue v.
    Wheeler, 
    324 U.S. 542

    the [later] clarifying amendment . . . added nothing to
    the liability of these taxpayers, and even though the
    Tax Court relied on it rather than on the regulation, no
    question of retroactivity is presented’’); ABKCO Music,
    Inc. v. LaVere, 
    217 F.3d 684
    , 689 (9th Cir.) (‘‘[i]f . . .
    [the statute] merely clarifies what [the prior statute]
    was originally intended to mean . . . it has no retroac-
    tive effect that might be called into constitutional ques-
    tion’’ [internal quotation marks omitted]), cert. denied,

    in 1976, required that property be passed to a qualified
    heir in order to qualify for special use valuation. As
    such, the 1978 clarifying amendment to that section
    did not change the law and was not retroactive in any
    substantive sense.’’).
    The judgment is affirmed with respect to the newspa-
    per’s cross appeal; the judgment is reversed with
    respect to the department’s appeal and the case is
    remanded to the trial court with direction to render
    judgment sustaining the department’s appeal.
    In this opinion the other justices concurred.

    The department also refused to produce Jane Smith’s medical records,
    which were part of exhibit C to Gfeller’s report. Jane Smith and John Smith
    intervened in the proceedings before the commission to contest disclosure
    of these records. The commission concluded that these records were not
    subject to disclosure, and the newspaper did not contest this determination
    on appeal. We therefore limit our discussion to the commission’s decision
    insofar as it addressed the data bank records.
    3
    The department appealed and the newspaper cross appealed to the
    Appellate Court, and we transferred the appeals to this court pursuant to
    General Statutes § 51-199 (c) and Practice Book § 65-1.

    The parties and the amicus have briefed at some length: (1) whether
    federal law requires this court to defer to the federal agency’s construction
    of the statutes and its own regulations, including its construction as reflected
    in a letter from that federal agency to Connecticut’s Office of the Attorney
    General while the present case was pending before the commission, a 2001
    guidebook published by that federal agency, and subsequent amendments
    to the regulations; and (2) whether this court’s construction of one of the
    regulations in Director of Health Affairs Policy Planning v. Freedom of
    Information Commis
    sion, supra
    , 
    293 Conn. 180
    n.13, which is at odds with
    the federal agency’s construction, should be reconsidered in the absence
    of this court’s consideration of whether the federal agency had adopted an
    interpretation that should be afforded deference.
    Under federal law, as a general rule, courts are required to defer to an
    agency’s reasonable construction of an ambiguous statute that the agency
    is charged with implementing; see Chevron U.S.A. Inc. v. Natural Resources
    Defense Council, Inc., 
    467 U.S. 837
    , 843–44, 
    104 S. Ct. 2778
    , 
    81 L. Ed. 2d 694
    (1984) (Chevron); as well as an agency’s reasonable construction of its
    own ambiguous regulation. See Auer v. Robbins, 
    519 U.S. 452
    , 461–62, 
    117 S. Ct. 905
    , 
    137 L. Ed. 2d 79
    (1997). There are, however, limitations to such
    deference. See generally Christopher v. SmithKline Beecham Corp., U.S.
    , 
    132 S. Ct. 2156
    , 2166–67, 
    183 L. Ed. 2d 153
    (2012) (citing circumstances
    in which deference is not afforded to agency interpretation). Under those
    circumstances in which deference is not afforded, the agency’s interpretation
    nonetheless is entitled to respect, but only to the extent that its interpretation
    has the power to persuade. See Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140,
    
    65 S. Ct. 161
    , 
    89 L. Ed. 124
    (1944). Whether Chevron/Auer deference or
    Skidmore’s less deferential standard applies, however, is not always clear
    in light of various factors that the United States Supreme Court has articu-
    lated in an evolving line of cases. See generally 1 R. Pierce, Administrative
    Law (5th Ed. 2010) § 3.5, p. 172 (‘‘Since 2000, the [United States Supreme]
    Court has issued over a dozen opinions in which it has attempted to clarify
    the scope of Chevron. Unfortunately, the only thing that emerges clearly
    from these opinions is that the Justices differ significantly with respect to
    their views on the scope of Chevron.’’).
    In the present case, the applicable standard is called into question by the
    fact that the critical sentence at issue in one of the regulations mirrors the
    statutory language; see Gonzales v. Oregon, 
    546 U.S. 243
    , 257, 
    126 S. Ct. 904
    , 
    163 L. Ed. 2d 748
    (2006) (declining to afford Auer deference when ‘‘the
    underlying regulation does little more than restate the terms of the statute
    itself’’); as well as the nature of the evidence on which the amicus relies—
    including an opinion letter and a guidebook. Compare 
    id. (declining to
    afford
    deference when circumstance in which interpretation was expounded was
    not one that Congress would have thought of as deserving deference), Coeur
    Alaska, Inc. v. Southeast Alaska Conservation Council, 
    557 U.S. 261
    , 283–84,
    
    129 S. Ct. 2458
    , 
    174 L. Ed. 2d 193
    (2009) (no substantial deference to memo-
    randum issued by agency), and Christensen v. Harris County, 
    529 U.S. 576
    ,
    587, 
    120 S. Ct. 1655
    , 
    146 L. Ed. 2d 621
    (2000) (no deference to policy
    statements, agency manuals, and enforcement guidelines), with Auer v.
    
    Robbins, supra
    , 
    519 U.S. 462
    (deference to interpretation articulated in legal
    brief). Because our interpretation is consistent with the federal agency’s
    own interpretation and relies on the federal agency’s pronouncements to
    the extent that they are persuasive, we conclude that we need not determine
    whether Chevron/Auer deference is required. Cf. Edelman v. Lynchburg
    College, 
    535 U.S. 106
    , 114, 
    122 S. Ct. 1145
    , 
    152 L. Ed. 2d 188
    (2002) (‘‘[T]here
    is no need to resolve any question of deference here. We find the [agency’s]
    rule not only a reasonable one, but the position we would adopt even if
    there were no formal rule and we were interpreting the statute from scratch.
    Because we so clearly agree with the [agency], there is no occasion to defer
    and no point in asking what kind of deference, or how much.’’).

    The principal issue in Director of Health Affairs Policy Planning v.
    Freedom of Information Commis
    sion, supra
    , 
    293 Conn. 164
    , was whether
    peer review records created by a state public agency were exempt from
    disclosure under the act pursuant to General Statutes § 19a-17b (d). The
    plaintiff agency offered no interpretation of the last sentence of 45 C.F.R.
    § 60.13 (a) in its brief to this court, and we did not have the benefit of briefing
    from the federal government. Although ‘‘our adherence to the doctrine of
    stare decisis serves the fundamental interest of our judicial system in stability
    and consistency . . . [i]t is more important that the court should be right
    upon later and more elaborate consideration of the cases than consistent
    with previous declarations. . . . This principle is particularly appropriate
    when we interpret federal law, as we do in this case, because in such a
    case our state legislature is powerless to correct our errors.’’ (Citations

    ‘‘convinces us that we must modify our analysis in order to reflect accurately

    Id., 571. Accordingly,
    we reject the conclusion of Director of Health Affairs Policy Planning to
    the limited extent that it is inconsistent with the reasoning of this opinion.

    The regulation confuses this context by inserting the intervening sen-
    tence that provides: ‘‘Persons and entities which receive information from
    the [Practitioner Data Bank] either directly or from another party must use
    it solely with respect to the purpose for which it was provided.’’ (Emphasis
    added.) 45 C.F.R. § 60.13 (a) (2009).

    Drawing on case law from the United States Supreme Court and other
    Circuit Courts of Appeals, the Eleventh Circuit Court of Appeals has
    explained: ‘‘[C]ourts may rely upon a declaration by the enacting body that
    its intent is to clarify the prior enactment. . . . Courts should examine such
    declarations carefully, however, especially if the declarations are found in
    the amendment’s legislative history rather than the text of the amendment
    itself. . . . As a general rule, [a] mere statement in a conference report of
    [subsequent] legislation as to what the [c]ommittee believes an earlier statute
    meant is obviously less weighty than a statement in the amendment itself.
    . . . Declarations in the subsequent legislative history nonetheless may be
    relevant to this analysis, especially if the legislative history is consistent
    with a reasonable interpretation of the prior enactment and its legislative
    history.’’ (Citations omitted; internal quotation marks omitted.) Cortes v.

    ‘‘Two commenters asked [the Health Resources and Services Adminis-
    tration of the federal agency charged with promulgating the regulations
    (agency)] to describe to what extent [Practitioner Data Bank] confidentiality
    would be protected and whether state Freedom of Information Acts (FOIA)
    would apply to the information contained in the [Practitioner Data Bank].
    Another commenter asked [the agency] to revise language in this section
    to strike the phrase ‘from its own files to create such reports’ regarding the
    disclosure of information by a party under applicable state or Federal law.
    This third commenter expressed concerns that this inserted language might
    invite researchers and others to seek out the reporting entity to ask for
    information from the entities’ own files and felt that the proposed change
    was ‘superfluous’.
    ‘‘Response: Information reported to the [Practitioner Data Bank] is consid-
    ered confidential, and access to and use of the information is prescribed
    by the three statutes that govern the [Practitioner Data Bank]. As stated in
    [45 C.F.R.] § 60.20 [2013], ‘Persons and entities receiving information from
    the [Practitioner Data Bank], either directly or from another party, must
    use it solely with respect to the purpose for which it was provided.’ Both
    improper use and access to [Practitioner Data Bank] information may result
    in a civil monetary penalty that is currently set at up to $11,000 for each
    violation. The Privacy Act also protects the contents of Federal records on
    individuals from disclosure without the individual’s consent, unless the
    disclosure is for a routine use of the system of records as published annually
    in the Federal Register. The published routine uses of [Practitioner Data
    Bank] information, which are based on the laws and the regulations under
    which the [Practitioner Data Bank] operates, do not allow disclosure to the
    general public. Given these statutory restrictions on [Practitioner Data
    Bank] information, [Practitioner Data Bank] information is not releasable
    through FOIA.
    ‘‘The confidentiality provisions prohibit the release of the report submitted
    to the Data Bank. These provisions, though, do not apply to the original
    documents or records from which the reported information is obtained. The
    [Practitioner Data Bank’s] confidentiality provisions do not impose any
    new confidentiality requirements or restrictions on those documents or
    records. Thus, the confidentiality provisions do not bar or restrict the release
    of the underlying documents, or the information itself, by the entity taking
    the adverse action or making the payment in settlement of a written medical
    malpractice complaint or claim. For this reason we inserted clarifying
    language in [45 C.F.R.] § 60.20 [2013], which already existed in the [Health-
    care Data Bank] regulations, stating that an entity is free to release informa-
    tion ‘from its own files’ provided that such disclosure is otherwise permitted
    by state and Federal law.
    ‘‘This provision allows the disclosure of information used to create [a
    Practitioner Data Bank] report, consistent with other legal requirements,
    however it does not permit the release of the [Practitioner Data Bank] report
    itself. So, for instance, if a state FOIA law requires the release of records,
    while it may require the release of the records underlying the report, it
    would not permit the release of the [Practitioner Data Bank] report itself.’’
