  •       TEXAS COURT OF APPEALS, THIRD DISTRICT, AT AUSTIN
    NO. 03-09-00250-CV
    Texas Commission on Environmental Quality, Appellant
    v.
    The Honorable Greg Abbott, Attorney General of Texas;
    and the Honorable Eliot Shapleigh, Texas Senator, Appellees
    FROM THE DISTRICT COURT OF TRAVIS COUNTY, 345TH JUDICIAL DISTRICT
    NO. D-1-GN-08-001855, HONORABLE SCOTT H. JENKINS, JUDGE PRESIDING
    OPINION
    In this appeal, the Texas Commission on Environmental Quality seeks reversal of the
    district court’s judgment requiring the Commission to disclose certain confidential and privileged
    documents to Texas Senator Eliot Shapleigh. The issue presented is whether separation of powers
    limits the legislature’s authority to obtain confidential and privileged communications between a
    state agency and its lawyers pursuant to section 552.008 of the Texas Public Information Act. See
    Tex. Gov’t Code Ann. § 552.008 (West 2004). Because we conclude that section 552.008 requires
    disclosure of the documents at issue to Senator Shapleigh, we affirm the judgment.
    BACKGROUND
    The facts of this cause are largely undisputed. In 2008, Senator Eliot Shapleigh
    intervened in an administrative proceeding before the Commission involving a request by
    Asarco, Inc., to renew its air quality permit in order to reopen its copper smelting plant in El Paso,
    Texas. Shortly after the Commission issued a final order granting the permit application, Senator
    Shapleigh made two separate requests1 for documents from the Commission under the Texas Public
    Information Act.2 See Tex. Gov’t Code Ann. §§ 552.001-.353 (West 2004 & Supp. 2009). In both
    requests, Senator Shapleigh requested documents pursuant to “the legislative purpose special right
    of access in Section 552.008 . . . .”
    At the time of Senator Shapleigh’s requests, section 552.008 provided:
    (a)     This chapter does not grant authority to withhold information from individual
    members, agencies, or committees of the legislature to use for legislative
    purposes.
    (b)     A governmental body on request by an individual member, agency, or
    committee of the legislature shall provide public information, including
    confidential information, to the requesting member, agency, or committee for
    inspection or duplication in accordance with this chapter if the requesting
    member, agency, or committee states that the public information is requested
    under this chapter for legislative purposes. A governmental body, by
    providing public information under this section that is confidential or
    otherwise excepted from required disclosure under law, does not waive or
    affect the confidentiality of the information for purposes of state or federal
    law or waive the right to assert exceptions to required disclosure of the
    information in the future. The governmental body may require the requesting
    individual member of the legislature, the requesting legislative agency or
    committee, or the members or employees of the requesting entity who will
    view or handle information that is received under this section and that is
    confidential under law to sign a confidentiality agreement that covers the
    information and requires that:
    1
    Senator Shapleigh’s first request was a letter to the Commission dated February 14, 2008.
    His second request was a letter to the Commission dated February 18, 2008.
    2
    Senator Shapleigh withdrew as a party to the administrative proceedings after the
    Commission refused to disclose certain documents in response to his requests.
    2
    (1)    the information not be disclosed outside the requesting entity, or
    within the requesting entity for purposes other than the purpose for
    which it was received;
    (2)    the information be labeled as confidential;
    (3)    the information be kept securely; or
    (4)    the number of copies made of the information or the notes taken from
    the information that implicate the confidential nature of the
    information be controlled, with all copies or notes that are not
    destroyed or returned to the governmental body remaining
    confidential and subject to the confidentiality agreement.
    (c)     This section does not affect:
    (1)    the right of an individual member, agency, or committee of the
    legislature to obtain information from a governmental body under
    other law, including under the rules of either house of the legislature;
    (2)    the procedures under which the information is obtained under other
    law; or
    (3)    the use that may be made of the information obtained under other
    law.3
    The Commission made several documents available to Senator Shapleigh but declined
    to disclose certain documents that it deemed privileged attorney-client communications and attorney
    work product. 
    Id. § 552.305
    (West 2004). Included among the documents withheld by the
    Commission were documents prepared by the Commission’s Office of General Counsel to advise
    3
    Tex. Gov’t Code Ann. § 552.008 (West 2004) (effective until September 1, 2010). The
    legislature enacted various amendments to section 552.008 in 2009; however, these amendments do
    not affect the outcome of this case. See Act of May 30, 2009, 81st Leg., R.S., ch. 1377, § 2, 2009
    Tex. Gen. Laws 4326, 4326-27; Act of May 27, 2009, 81st Leg., R.S., ch. 1364, § 1, 2009 Tex. Gen.
    Laws 4304, 4304-05. For convenience, we cite to the current statute.
    3
    the Commissioners regarding the Asarco application. Also included were documents prepared by
    lawyers in the Environmental Law Division who advise the executive director of the Commission.
    The Commission forwarded all of these documents to the Open Records Division of
    the Office of the Attorney General and requested a ruling under section 552.301 of the public
    information act.4 See 
    id. § 552.301
    (West 2004). The Commission asserted that its documents were
    excepted from disclosure under sections 552.101 (confidential under other law), 552.103
    (information related to litigation), 552.107 (attorney-client privilege), and 552.111 (agency
    memoranda and deliberative process privilege) of the act. See Tex. Gov’t Code Ann. §§ 552.101,
    .103, .107, .111 (West 2004). In conjunction with its claim under section 552.101, the Commission
    also asserted that its documents were excepted from disclosure under Texas Rule of Evidence 503
    and Texas Rule of Civil Procedure 192.5. See 
    id. § 552.101;
    Tex. R. Evid. 503; Tex. R. Civ. P.
    192.5. The Commission further claimed that disclosure of its documents to Senator Shapleigh would
    “disturb the effective separation of powers [under article II, section 1, of the Texas Constitution]
    because the legislative function would be in the position to interfere with the judicial and executive
    functions.” See Tex. Const. art. II, § 1.
    The attorney general issued an informal letter ruling, OR2008-06742, which
    interpreted the public information act to require disclosure of all documents held by the
    Commission’s general counsel and Environmental Law Division to Senator Shapleigh. See Tex.
    Att’y Gen. OR2008-06742 (May 16, 2008).               The attorney general declined to address the
    4
    The Commission’s general counsel forwarded documents held by the general counsel’s
    office, and a lawyer in the Commission’s Environmental Law Division forwarded documents held
    by that division to the attorney general’s office.
    4
    Commission’s assertions that its documents were confidential under Texas Rule of Evidence 503
    or Texas Rule of Civil Procedure 192.5 in conjunction with section 552.101 of the act because the
    attorney general had previously “concluded that section 552.101 does not encompass discovery
    privileges.” See OR2008-06742 at 1 n.1 (citing Tex. Att’y Gen. ORD Nos. 676 at 1-2 (2002),
    575 at 2 (1990)). Finding that the Commission “failed to sufficiently demonstrate that such
    interference [wa]s present in the instant case,” the attorney general rejected the Commission’s claim
    that release of the subject documents would raise separation of powers concerns. 
    Id. at 3.
    The
    attorney general concluded that the Commission’s documents were subject to disclosure under
    section 552.008 of the public information act and, therefore, declined to address the Commission’s
    remaining arguments. 
    Id. The Commission
    sued the attorney general in district court, and Senator Shapleigh
    intervened. See Tex. Gov’t Code Ann. §§ 552.324(a), .325 (West 2004). Senator Shapleigh filed
    a motion for summary judgment. See Tex. R. Civ. P. 166a(c). The Commission also sought
    summary judgment, but the attorney general did not. The district court granted the senator’s motion
    and denied the motion of the Commission. This appeal followed.
    ANALYSIS
    The Commission contends that the district court erred in concluding that
    section 552.008 of the public information act requires the Commission to disclose the documents
    at issue to Senator Shapleigh because the statute and Senator Shapleigh’s requests violate the
    separation of powers doctrine embodied in article II, section 1, of the Texas Constitution. Senator
    Shapleigh and the attorney general respond that there was no error in the district court’s judgment
    5
    because the Commission cannot show that the statute or Senator Shapleigh’s requests amounted to
    undue interference with a core function constitutionally committed to the Commission.
    Standard of Review
    We review the district court’s grant of summary judgment de novo.5 Valence
    Operating Co. v. Dorsett, 
    164 S.W.3d 656
    , 661 (Tex. 2005). To prevail on a summary judgment
    motion, the movant must show that there are no genuine issues of material fact and that he is entitled
    to judgment as a matter of law. Tex. R. Civ. P. 166a(c).
    Determining whether an exception applies under the public information act to support
    withholding of public information is a question of law, which we review de novo. See City of
    Garland v. Dallas Morning News, 
    22 S.W.3d 351
    , 357 (Tex. 2000); City of Fort Worth v. Cornyn,
    
    86 S.W.3d 320
    , 323 (Tex. App.—Austin 2002, no pet.). We construe the act liberally in favor of
    granting requests for information, while narrowly construing exceptions to disclosure. See Tex.
    Gov’t Code Ann. § 552.001(b) (West 2004); City of 
    Garland, 22 S.W.3d at 365
    .
    We consider questions of statutory construction de novo as well. See City of San
    Antonio v. City of Boerne, 
    111 S.W.3d 22
    , 25 (Tex. 2003). When construing a statute, our primary
    goal is to determine and give effect to the legislature’s intent. 
    Id. To determine
    legislative intent, we
    5
    Because the attorney general did not seek summary judgment, our review is limited to
    whether the district court properly granted summary judgment in favor of Senator Shapleigh. See
    Ackermann v. Vordenbaum, 
    403 S.W.2d 362
    , 365 (Tex. 1966); see also Montgomery v. Blue Cross
    & Blue Shield of Tex., Inc., 
    923 S.W.2d 147
    , 152 (Tex. App.—Austin 1996, writ denied) (“Before
    an appellate court may reverse summary judgment for one party and render judgment for the other
    party, all parties must have sought final judgment relief in their cross-motions for summary
    judgment.”). Therefore, we do not consider whether the district court erred in denying summary
    judgment to the Commission. See 
    Ackermann, 403 S.W.2d at 365
    .
    6
    look to the statute as a whole, as opposed to isolated provisions. State v. Gonzalez, 
    82 S.W.3d 322
    ,
    327 (Tex. 2002). We begin with the plain language of the statute at issue and apply its common
    meaning. City of San 
    Antonio, 111 S.W.3d at 25
    . Where the statutory text is unambiguous, we
    adopt a construction supported by the statute’s plain language unless that construction would lead
    to an absurd result. Fleming Foods of Tex., Inc. v. Rylander, 
    6 S.W.3d 278
    , 284 (Tex. 1999).
    We construe Texas constitutional provisions in the same manner as we construe
    statutes. Harris County Hosp. Dist. v. Tomball Reg’l Hosp., 
    283 S.W.3d 838
    , 842 (Tex. 2009);
    Doody v. Ameriquest Mortgage Co., 
    49 S.W.3d 342
    , 344 (Tex. 2001). The guiding rule is to discern
    and give effect to the intent of the provision’s drafters. Harris County Hosp. 
    Dist., 283 S.W.3d at 842
    ; City of El Paso v. El Paso Cmty. Coll. Dist., 
    729 S.W.2d 296
    , 298 (Tex. 1986). We rely heavily
    on the literal text of a constitutional provision to give effect to its plain language. Harris County
    Hosp. 
    Dist., 283 S.W.3d at 842
    ; 
    Doody, 49 S.W.3d at 344
    . If the plain language of a constitutional
    provision is clear and unambiguous, resort to extrinsic aids and rules of construction is inappropriate,
    and we give the language of the provision its common everyday meaning. City of Rockwall
    v. Hughes, 
    246 S.W.3d 621
    , 625-26 (Tex. 2008); State v. Shumake, 
    199 S.W.3d 279
    , 284 (Tex.
    2006). This rule provides an objective guidepost to discern the drafter’s intent and ensures that
    ordinary citizens may “rely on the plain language . . . to mean what it says.” Fitzgerald v. Advanced
    Spine Fixation Sys., Inc., 
    996 S.W.2d 864
    , 866 (Tex. 1999).
    Legislative Access Under Section 552.008
    We address as an initial matter the Commission’s proposed construction of section
    552.008. As part of its argument, the Commission asserts that we may interpret section 552.008 in
    7
    a manner that avoids the constitutional question of separation of powers. Specifically, the
    Commission contends that we may employ a heightened standard of interpretation to construe the
    phrase “including confidential information” in subsection 552.008(b) to exclude the documents at
    issue in this case—i.e., documents protected by the attorney-client and work-product privileges.
    As a general rule, we agree with the Commission that courts should construe statutes
    in a manner that renders them constitutional and gives effect to the legislature’s intent. See Quick
    v. City of Austin, 
    7 S.W.3d 109
    , 115 (Tex. 1998); see also Sweeney v. Jefferson, 
    212 S.W.3d 556
    ,
    565 (Tex. App.—Austin 2006, no pet.) (courts should avoid deciding constitutional question when
    possible). However, the Commission provides no authority for its heightened statutory construction
    argument, and we have found none.
    The starting point for construing a statute is the language of the statute itself. In re
    City of Georgetown, 
    53 S.W.3d 328
    , 331 (Tex. 2001). The plain language of subsection 552.008(b)
    requires the Commission “on request by an individual member, agency, or committee of the
    legislature [to] provide public information, including confidential information,” if the information
    is requested for legislative purposes. Tex. Gov’t Code Ann. § 552.008(b). There is nothing
    ambiguous about the phrase “confidential information.” 
    Id. In the
    context of the attorney-client
    relationship, the state bar disciplinary rules define “confidential information” to encompass even
    unprivileged client information. Tex. Disciplinary R. Prof. Conduct 1.05(a) (eff. Jan. 1, 1990),
    reprinted in Texas Rules of Court: State 507 (West 2009) (State Bar Rules art. X, § 9). Applying
    this definition, the Texas Supreme Court has held, “[V]irtually any information relating to a case
    should be considered confidential.” See Phoenix Founders v. Marshall, 
    887 S.W.2d 831
    , 834 (Tex.
    8
    1994). The Texas Court of Criminal Appeals has also recognized, “‘Confidential information’ is,
    by definition, information that is available only to authorized persons; it is ‘classified,’ ‘privileged,’
    ‘private,’ ‘secret,’ ‘restricted.’” Landers v. State, 
    256 S.W.3d 295
    , 309 (Tex. Crim. App. 2008)
    (quoting “Confidential,” Roget’s II: The New Thesaurus (3rd ed. 1995)). The plain meaning of this
    phrase includes documents subject to the attorney-client or work-product privileges.                Such
    documents would also constitute information that is “excepted from required disclosure” or
    “confidential under other law.” See In re City of 
    Georgetown, 53 S.W.3d at 332
    (holding that rules
    of civil procedure and evidence are “other law” for purposes of section 552.022 of public
    information act).
    Adopted in 1973, the Texas Public Information Act is modeled on the federal
    Freedom of Information Act. City of Fort Worth v. Cornyn, 
    86 S.W.3d 320
    , 323 (Tex. App.—Austin
    2002, no pet.). The language in section 552.008(a), which states “This chapter does not grant
    authority to withhold information from individual members, agencies, or committees of the
    legislature to use for legislative purposes,” is strikingly similar to section 552(d) of the FOIA,
    formerly section 552(c), which states, “This section does not authorize withholding of information
    or limit the availability of records to the public, except as specifically stated in this section. This
    section is not authority to withhold information from Congress.” See 5 U.S.C. § 552(d) (emphasis
    added). The Texas Supreme Court has explained that, when the legislature adopts a federal statute,
    Texas courts must presume that the legislature knew of the federal courts’ construction of the federal
    statute and intended to adopt that construction. City of 
    Garland, 22 S.W.3d at 360
    (citing Blackmon
    9
    v. Hansen, 
    169 S.W.2d 962
    , 964-65 (Tex. 1943)). We may therefore look to the federal courts’
    construction of the FOIA for guidance in interpreting the Texas act. 
    Id. When interpreting
    section 552(d), federal courts have consistently held that Congress
    reserved unto itself a special right of access to governmental information. See, e.g., Murphy
    v. Department of the Army, 
    613 F.2d 1151
    , 1157 (D.C. Cir. 1979). These same federal courts have
    recognized that federal agencies may not use section 552(b)(5), or Exemption 5—including the
    attorney-client, work-product, and deliberative-process privileges—to withhold information from
    Congress, its committees, or its individual members, when requested in their official capacity for
    legislative use. See 
    id. As the
    court of appeals explained in Murphy, when enacting the FOIA,
    Congress intended to maintain its ready access to information necessary for it to fulfill its legislative
    function but not to override, directly or indirectly, all of the exemptions from general disclosure
    written into the FOIA. See 
    id. at 1156
    n.12.
    Applying the federal courts’ interpretation of the FOIA to the language of section
    552.008, it is clear that the Texas Legislature, like Congress, intended to maintain for itself a special
    right of access to confidential governmental information necessary to fulfill its legislative function
    without overriding the exemptions to required disclosure written into the Texas act. See id.; see also
    Terrell v. King, 
    14 S.W.2d 786
    , 790 (Tex. 1929) (“[C]onstitutional provisions which commit the
    legislative function to the two houses are intended to include [the power to investigate] to the end
    that the function may be effectively exercised.”). Authority to pursue investigations and inquiries
    has long been regarded as an incident of full legislative power. 
    Terrell, 14 S.W.2d at 789-90
    . We
    10
    therefore conclude that the phrase “confidential information” in section 552.008 is sufficient to
    include the documents at issue, and we reject the Commission’s statutory construction argument.
    We turn to the Commission’s separation of powers claim.
    Separation of Powers
    The Commission argues that section 552.008 and, by extension, Senator Shapleigh’s
    requests violate the separation of powers because they invade the exclusive power of the
    Commission to carry out its constitutionally delegated functions under article XVI, section 59 of the
    Texas Constitution. Specifically, the Commission argues that section 552.008 causes a chilling
    effect on the authority constitutionally committed to the Commission to regulate in the area of
    natural resources.     Thus, the Commission contends, section 552.008 and Senator Shapleigh’s
    requests unduly interfere with the Commission’s authority as derived from the Texas Constitution.
    Article II, section 1 of the Texas Constitution, which governs separation of powers,
    states:
    The powers of the Government of the State of Texas shall be divided into three
    distinct departments, each of which shall be confided to a separate body of
    magistracy, to wit: Those which are Legislative to one; those which are Executive to
    another, and those which are Judicial to another; and no person, or collection of
    persons, being of one of these departments, shall exercise any power properly
    attached to either of the others, except in the instances herein expressly permitted.
    Tex. Const. art. II, § 1. This provision confirms the prohibition against one branch of government
    exercising a power inherently belonging to another branch. See General Servs. Comm’n v. Little-Tex
    Insulation Co., 
    39 S.W.3d 591
    , 600 (Tex. 2001).
    11
    Although the language of this provision “appears on its face to be rigid and absolute[,]
    . . . such a construction would be impossible to implement in all cases because not every
    governmental power fits logically and clearly into any particular ‘department.’” Holmes v. Morales,
    
    906 S.W.2d 570
    , 573 (Tex. App.—Austin 1995), rev’d in part on other grounds, 
    924 S.W.2d 920
    (Tex. 1996). When construing separation of powers under the federal Constitution, the United States
    Supreme Court “ha[s] never held that the Constitution requires that the three branches of
    Government ‘operate with absolute independence,’” see Morrison v. Olson, 
    487 U.S. 654
    , 693-94
    (1988) (quoting United States v. Nixon, 
    418 U.S. 683
    , 707 (1974)), choosing instead to adopt
    “Madison’s flexible approach to separation of powers,” Mistretta v. United States, 
    488 U.S. 361
    , 380
    (1989), and “uph[o]ld statutory provisions that to some degree commingle the functions of the
    Branches, but that pose no danger of either aggrandizement or encroachment.” 
    Id. at 382.
    In the
    words of Justice Jackson:
    While the Constitution diffuses power the better to secure liberty, it also
    contemplates that practice will integrate the dispersed powers into a workable
    government. It enjoins upon its branches separateness but interdependence,
    autonomy but reciprocity.
    Youngstown Sheet & Tube Co. v. Sawyer, 
    343 U.S. 579
    , 635 (1952) (Jackson, J., concurring).
    Like their federal counterparts, Texas courts have long held that some degree of
    interdependence and reciprocity is subsumed within the separation of powers principle. Id.; see
    Government Servs. Ins. Underwriters v. Jones, 
    368 S.W.2d 560
    , 562 (Tex. 1963); State Bd. of Ins.
    v. Betts, 
    308 S.W.2d 846
    , 852 (Tex. 1958); 1 George D. Braden et al., The Constitution of the State
    of Texas: An Annotated and Comparative Analysis 98 (1977) (“The separation principle is not and
    12
    cannot be rigid.”). Addressing the relationship between separateness and efficacy, the Texas
    Supreme Court stated:
    Co-ordination or co-operation of two or more branches or departments of government
    in the solution of certain problems is both the usual and expected thing. . . . The
    system of checks and balances running throughout the governmental structure[,]
    while designed to prevent excesses, is not intended to make effective action
    impossible.
    
    Betts, 308 S.W.2d at 852
    .
    While some degree of interdependence and reciprocity is permissible, Texas courts
    have consistently recognized that separation of powers may be violated in either of two ways:
    First, it is violated when one branch of government assumes, or is delegated, to
    whatever degree, a power that is more “properly attached” to another branch. The
    provision is also violated when one branch unduly interferes with another branch so
    that the other branch cannot effectively exercise its constitutionally assigned powers.
    Jones v. State, 
    803 S.W.2d 712
    , 715-16 (Tex. Crim. App. 1991) (quoting Armadillo Bail Bonds
    v. State, 
    802 S.W.2d 237
    , 239 (Tex. Crim. App. 1990)) (citations and emphases omitted). The
    Commission does not allege that the legislature, by enacting section 552.008, or Senator Shapleigh,
    by requesting information under the public information act, has assumed or exercised a power that
    is more “properly attached” to the executive branch of government. Rather the Commission argues
    that section 552.008 and the Senator’s requests “unduly interfere” with the Commission’s exercise
    of its constitutionally assigned powers.
    To determine whether a separation of powers violation involving “undue interference”
    has occurred, we engage in a two-part inquiry. See Armadillo Bail Bonds v. State, 
    802 S.W.2d 237
    ,
    13
    239 (Tex. Crim. App. 1990). We look first to the scope of the Commission’s constitutionally
    assigned powers and, then, we consider the impact of the statute and the Senator’s requests upon the
    Commission’s exercise of those powers. 
    Id. (appellate inquiry
    begins with nature of constitutional
    power and extent to which legislative encroachment is permitted).
    Constitutional Powers Assigned to the Commission
    The Commission asserts that it derives constitutional authority from article XVI,
    section 59, of the Texas Constitution. In relevant part, article XVI, section 59—also known as the
    Conservation Amendment—provides:
    (a)     The conservation and development of all of the natural resources of this
    State, and development of parks and recreational facilities, including the
    control, storing, preservation and distribution of its storm and flood waters,
    the waters of its rivers and streams, for irrigation, power and all other useful
    purposes, the reclamation and irrigation of its arid, semi-arid and other lands
    needing irrigation, the reclamation and drainage of its overflowed lands, and
    other lands needing drainage, the conservation and development of its forests,
    water and hydro-electric power, the navigation of its inland and coastal
    waters, and the preservation and conservation of all such natural resources of
    the State are each and all hereby declared public rights and duties; and the
    Legislature shall pass all such laws as may be appropriate thereto.
    Tex. Const. art. XVI, § 59(a) (emphasis added). The plain language of this provision assigns the
    power to enact laws relating to conservation and development of natural resources not to the
    Commission, but to the legislature. Subsection (a) of this provision states “ . . . and the Legislature
    shall pass all such laws as may be appropriate thereto.” 
    Id. Subsection (b)
    authorizes the creation
    of conservation and reclamation districts, and subsection (c) permits the legislature to authorize
    indebtedness and the levy and collection of taxes within such districts provided, however, that such
    14
    proposition be first submitted to and adopted by qualified voters of a district. 
    Id. § 59(b)-(c).
    Nowhere in this provision does the constitution mention the Commission or otherwise delegate
    authority to the Commission. 
    Id. § 59.
    Based on its plain language then, the Commission derives
    no constitutionally assigned power from article XVI, section 59, of the Texas Constitution.
    To the extent the Commission claims to derive constitutional authority from
    article IV, section 10, we likewise reject that contention. Article IV, section 10 states:
    [The Governor] shall cause the laws to be faithfully executed and shall conduct, in
    person, or in such manner as shall be prescribed by law, all intercourse and business
    of the State with other States and with the United States.
    Tex. Const. art. IV, § 10. Like article XVI, section 59, article IV, section 10, makes no mention of
    the Commission. See 
    id. While the
    parties do not dispute that the Commission functions within the
    realm of the executive branch, we cannot conclude that such functioning brings the Commission
    within the scope of any constitutional authority granted by article IV, section 10. See 
    Holmes, 906 S.W.2d at 572
    (ascribing different meanings to the terms “judiciary” and “Judicial
    Department”). The plain language of article IV, section 10, does not grant any constitutional
    authority to the Commission.
    Our conclusions that the Commission does not derive constitutional authority from
    either article XVI, section 59, or article IV, section 10, are further supported by the longstanding
    recognition that agencies are creatures of statute and have no inherent authority. Public Util.
    Comm’n v. GTE-Southwest, Inc., 
    901 S.W.2d 401
    , 406-07 (Tex. 1995). Although we recognize that
    the legislature may create an administrative agency, like the Commission, and delegate its legislative
    15
    powers thereto, such powers are derived from statute, not the Texas Constitution. Id.; see also Texas
    Boll Weevil Eradication Found., Inc. v. Lewellen, 
    952 S.W.2d 454
    , 467 (Tex. 1997); Railroad
    Comm’n v. Lone Star Gas Co., 
    844 S.W.2d 679
    , 689 (Tex. 1992). More importantly, an agency may
    exercise only those powers expressly delegated by statute and those powers necessarily implied to
    carry out the specific powers delegated. Public Util. 
    Comm’n, 901 S.W.2d at 406-07
    ; McDaniel
    v. Texas Natural Res. Conservation Comm’n, 
    982 S.W.2d 650
    , 651-52 (Tex. App.—Austin 1998,
    pet. denied); Sexton v. Mount Olivet Cemetery Ass’n, 
    720 S.W.2d 129
    , 137-39 (Tex. App.—Austin
    1986, writ ref’d n.r.e.).
    In support of its separation of powers argument, the Commission relies on an informal
    letter ruling issued by the attorney general in response to a request for information by a Texas House
    Representative. See Tex. Att’y Gen. OR2008-02184 (Feb. 15, 2008). The representative requested
    public information from the attorney general himself pursuant to section 552.008. The attorney
    general argued that specific documents responsive to the request were exempt from disclosure
    because they were privileged attorney-client communications and disclosure would infringe upon
    the attorney general’s constitutional authority to render advisory opinions in violation of the
    separation of powers doctrine. In his letter ruling, the attorney general explained that article IV,
    section 22 of the Texas Constitution confers exclusive authority to issue advisory opinions on the
    attorney general and no constitutional provision conferred such power on the legislature. See 
    id. at 2-3.
    The attorney general concluded that allowing legislative access to the attorney general’s
    internal deliberations would unduly interfere with the effective exercise of his constitutional power
    to render a written advisory opinion. See 
    id. at 3.
    16
    The Commission’s reliance on this letter ruling is misplaced. Unlike the attorney
    general, the Commission derives no specific power from the Texas Constitution. In the absence of
    constitutional authority assigned to the Commission, there can be no separation of powers violation
    occasioned by the legislature’s enactment of section 552.008 or the Senator’s requests for
    information under that statute. See 
    Holmes, 906 S.W.2d at 574
    (“It is quite evident that the office
    of district attorney has by statutory delegation the duty and power to represent the state in criminal
    cases in district court. We must find that delegation in the constitution, however, before a
    separation-of-powers problem arises.” (citation omitted)). Because we find no constitutional
    authority committed to the Commission and, therefore, no separation of powers violation, we can
    affirm the district court’s judgment on this ground alone without considering the second prong of
    the inquiry.
    Permissible Legislative Encroachment
    Nevertheless, even if we agreed with the Commission that it derives authority to issue
    air quality permits from the Constitution, to reverse the district court’s judgment we would still have
    to find that the legislature’s enactment of section 552.008 unduly interferes with the Commission’s
    exercise of constitutional authority.
    “The power and authority of a state legislature is plenary and its extent is limited only
    by the express or implied restrictions thereon contained in or necessarily arising from the
    Constitution itself.” Government Servs. Ins. 
    Underwriters, 368 S.W.2d at 563
    . When the legislature
    enacts a statute, it exercises a power “properly attached” to the legislative branch of government.
    
    Jones, 803 S.W.2d at 716
    . A constitutional problem arises, however, when legislative enactment
    17
    interferes with the core functioning of another branch of government in a field constitutionally
    committed to the control of that branch. Id.; see also Armadillo Bail 
    Bonds, 802 S.W.2d at 239
    (legislature may not interfere in core judicial functions). Stated differently, the legislature may not
    interfere with the core functions of the judicial or executive branches without running afoul of
    separation of powers.
    In support of its claim that section 552.008 unduly interferes with its permit granting
    authority, the Commission argues that release of its confidential documents to Senator Shapleigh
    would have a “chilling effect” on the free flow of ideas, frank communications, and the exchange
    of advice from the Commission’s attorneys and the Commission.6 But, the Commission cites no
    authority, and we have found none, for the proposition that some unspecified chilling effect alone
    would constitute sufficient undue interference to create a separation of powers violation.
    We further observe that subsection 552.008(b) protects the confidentiality of the
    Commission’s documents once they are disclosed pursuant to a legislative request for information.
    See Tex. Gov’t Code Ann. § 552.008(b). Subsection 552.008(b) preserves the confidentiality of the
    Commission’s documents while in the possession of Senator Shapleigh by authorizing the
    Commission to require Senator Shapleigh to sign a confidentiality agreement prior to receiving the
    documents at issue. See 
    id. In addition,
    subsection 552.008(b) expressly states that disclosure to
    6
    In support of this argument, the Commission relies on conclusory affidavits from two of
    the Commission’s attorneys. In each affidavit, the affiant states a personal opinion that disclosure
    would have a chilling effect on the attorney-client relationship or would inhibit the ability of agency
    attorneys to provide legal advice. But neither affiant explains how disclosure of the subject
    documents to a legislator would restrict the communication of legal advice between Commission
    administrators and their counsel.
    18
    Senator Shapleigh does not waive or otherwise affect the confidentiality of the documents for
    purposes of state or federal law, nor does disclosure to Senator Shapleigh under section 552.008
    prevent the Commission from asserting exceptions to required disclosure in response to future
    requests for these documents.7 See 
    id. These protections
    make clear that the legislature intended to
    give its members and committees a right of access even to confidential information. Accordingly,
    even were we to accept the Commission’s argument regarding its constitutional authority, we
    conclude the Commission has failed to demonstrate how disclosure of the documents at issue to
    Senator Shapleigh unduly interferes with the Commission’s exercise of that authority. We overrule
    the Commission’s separation of powers claim.
    CONCLUSION
    Because we conclude that section 552.008 requires disclosure of the documents at
    issue and the Commission has failed to demonstrate that such disclosure would unduly interfere with
    any constitutional authority committed to the Commission, we affirm the district court’s judgment.
    7
    In response to two other requests for these same documents, we observe that the attorney
    general agreed with the Commission that the documents at issue were exempt from disclosure under
    section 552.107 of the public information act. See Tex. Att’y Gen. OR2008-10112 (July 25, 2008),
    OR2008-06741 (May 16, 2008).
