Statement of the Case
The Indiana Access to Public Records Act (“APRA”) provides that “it is the public policy of the state that all persons are entitled to full and complete information regarding the affairs of government and the official acts of those who represent them as public officials and employees.” Ind. Code § 5-14-3-1 (Supp. 2014). Thus, in APRA our legislature declared that transparency in government is the public policy of the State of Indiana. But the public’s right of access to public records is also subject to well-recognized exceptions under APRA.
In December of 2014, Governor Mike Pence made the decision that Indiana would join a Texas lawsuit against the President of the United States to contest certain presidential executive orders on immigration. In response, William Groth, a *1109private citizen, submitted an APRA public records request to the Governor for records related to the Governor’s decision. The Governor responded to Groth’s request but, in doing so, partially redacted some of the documents and withheld another. The Indiana Public Access Counsel- or concluded that the Governor did not violate APRA. Acting on Groth’s ensuing complaint, the trial court also concluded that the Governor’s response was proper under APRA.
On appeal, the parties raise the following four issues for our review:
1. Whether the Indiana Supreme Court’s recent opinion in Citizens Action Coalition of Indiana v. Koch, 51 N.E.3d 236 (Ind. 2016), requires Indiana’s courts to abstain from reviewing the Governor’s decision to redact or withhold certain records from public disclosure.
2. Whether the trial court violated Groth’s due process rights when it did not provide him with a written summary of the contents of the undisclosed information after the court had reviewed that information in camera.
3. Whether the Governor violated APRA when he withheld from disclosure a legal memorandum, referred to by the parties as a “white paper,” created by a Texas deputy solicitor general concerning the proposed Texas litigation and disseminated to governors’ offices in Indiana and numerous other states.
4. Whether the Governor violated APRA when he partially redacted invoices from a private law firm he had hired to represent Indiana in the Texas lawsuit and on Groth’s complaint.
We hold that, on these facts, Citizens Action Coalition does not apply to the request for public records directed to the Governor. We also hold that the trial court did not violate Groth’s due process rights. And we affirm on the merits of the Governor’s decisions to withhold the white paper from public disclosure and to partially redact the invoices. The white paper contains legal theories in contemplation of litigation, was used by the Governor in his decision to join the litigation, and is exactly the type of record that may be excluded from public access under APRA. Similarly, the Governor’s redactions from the legal invoices were within his discretion under APRA.
Facts and Procedural History1
On December 10, 2014, Groth submitted a written request to the Governor’s office for documents relating to the Governor’s decision to join the State of Texas in a federal lawsuit against the President of the United States with respect to certain recent presidential executive orders on immigration. According to Groth’s request:
Pursuant to [APRA], I am hereby requesting public records that your office maintains concerning your discretionary decision to hire outside counsel at Barnes & Thornburg [LLP] to represent your office and/or the State of Indiana in litigation encaptioned State of Texas, et al[.] v. United States of America, pending in the United States District Court *1110for the Southern District of Texas, Brownsville Division, challenging the November 20, 2014, action of the President of the United States to exercise discretion with respect to certain individuals who came to the United States as children and whose parents are United States citizens or permanent residents. More specifically, I am requesting the following records pertaining to said lawsuit: (1) all correspondence between your office and the office of the Indiana Attorney General, any other state official, any governmental official from another state, or any private entity, with respect [to] your decision to become a party in [the] litigation; (2) the contract or agreement between your office and Barnes & Thornburg LLP, retaining that firm to represent you and/or the State of Indiana in said lawsuit; (3) any and all invoices from Barnes & Thorn-burg for professional services rendered or to be rendered in connection with said lawsuit; and (4) evidence of any payments made to Barnes & Thornburg for professional services rendered in connection with said lawsuit.
Appellant’s App. Yol. 2 at 12.
The Governor responded to Groth’s request with more than fifty pages of documents.2 The Governor redacted portions of several of those documents, and he declined to release the white paper, a legal memorandum. For example, part of the Governor’s response for invoices from Barnes & Thornburg LLP described the attorneys’ work as follows:
Worked on litigation, including review of district court filing notices and update reports from Texas counsel, and work on documenting potential damages to State. [Redacted] conferred with Angela Col-menero, assistant Attorney General in Texas, regarding declaration to support standing arguments; reviewed material forwarded by Ms. Colmenero; [redacted] began work on draft declaration.
Worked on litigation, including review of district court filing notices.
Reviewed amicus brief filed by various immigrant groups; communicated with Allison Earns about the amicus briefs; reviewed various draft declarations from Texas and Wisconsin representatives; [redacted] communicated with Angela Carmenero regarding declarations; communicated with Andy Oldham regarding hearing; [redacted].
Id. at 22. The invoices also described, without redactions, the dates of the services rendered, the names of the attorneys providing the services, the hours the attorneys logged for the services rendered, and the total invoice amounts.
Another document submitted by the Governor in response to Groth’s request was an unredacted email from Daniel Hodge, the chief of staff to then Texas Governor-Elect Greg Abbott, dated November 25, 2014. The subject of Hodge’s email was “Legal Challenge to President’s Executive Orders,” and Hodge addressed his email to the “Chiefs of Staff’ of governors in several different states.3 Id. at 30. According to Hodge:
*1111I am Texas Governor-Elect Greg Abbott’s Chief of Staff and am contacting you to follow-up on comments my boss made during the Govemors-Only meeting last week. As some of you may have heard, the State of Texas is preparing a legal challenge to the President’s recent executive orders on immigration. During last week’s meeting, Governor-Elect Abbott promised that we would circulate a white paper outlining the legal theories supporting the State’s legal challenge to the other Governors. A copy of that white paper is attached to this email.
Our hope is that other states will join the State of Texas’ legal action so that we will have a broad coalition to challenge the President’s action — just as we did when 26 states banded together to challenge ObamaCare. Because Gov-Elect Abbott currently serves as Attorney General of Texas, we have also contacted many of your Attorneys General to inquire about their interest in joining Texas’ legal challenge. Those offices have also been provided a copy of the attached white paper.
However, because some Governors indicated last week that their Attorneys General may not elect to join our legal challenge, Gov-Elect Abbott asked that I share this white paper with your office[s] so that Governors whose AGs decline to join the case may do so on behalf of their states. Deputy Solicitor General Andy Oldham is lead counsel for this matter and the drafter of the attached white paper....
Id. (emphases added). Although Hodge attached the white paper to his email, Governor Pence withheld release of that document in his response to Groth’s APRA request.
Groth complained about the Governor’s response to Indiana’s Public Access Counselor.4 According to Groth, the Governor’s response failed to comply with APRA. The Public Access Counselor disagreed, stating:
The Governor’s Office has provided a proper response ... as to why parts of the document were redacted. Pursuant to Ind. Code §§ 5-14-3-4(b)(2) and (6), the materials redacted may contain attorney work product and deliberative materials between interagency personnel and its designated contractor. Additionally, under Ind. Code § 34-46-3-1, the records may have been excluded because they include' attorney-client communication. The redaction of legal invoices for this purpose is not unusual and has been addressed as appropriate in several prior Public Access Counselor Opinions.
Pursuant to Ind. Code § 5-14-3-6, redac-tions should be made with precision so non-disclosable records are separated *1112from disclosable material; The redac-tions made to the records you have presented do not appear on their face to be overly redacted, relative, to other attorney invoices this Office has seen.
Public Access Counselor, Re: Formal Complaint 15-F&133; Alleged Violation of the Access to Public Records Act by the Office of Governor Mike Pence (May 27, 2015), http://in.gov/pac/advisory/files/15-FC-133.pdf. The Public Access Counselor then concluded that the Governor “did not violate the Access to Public Records Act.” Id.
Groth then filed his complaint in the Marion Superior Court. The trial court reviewed the unredacted invoices and previously undisclosed white paper in camera and concluded, after a hearing, that the Governor had complied with APRA. This appeal ensued.5
Discussion and Decision
Standard of Review
Groth appeals the trial court’s judgment for the Governor. Under the Indiana Code, the trial court’s review of Groth’s complaint for an alleged APRA violation was de novo, or without deference to the public agency6 that denied the access, and the initial burden of proof in the trial court was on the agency. I.C. § 5-14-3-9(f), (g)(1). The public agency meets its burden of proof by showing that the undisclosed records fall within an exception listed under Indiana Code Section 5-14-3-4 and by establishing the content of those records with adequate specificity beyond merely relying on a conclusory statement or affidavit. I.C. § 5-14-3-9(f), (g). If the undisclosed records fall within a mandatory exception listed under Indiana Code Section 5-14-3-4(a), as a matter of law the records shall not be disclosed. If the undisclosed records fall within a discretionary exception listed under Indiana Code Section 5-14-3-4(b), it is in the agency’s discretion not to disclose the records. Once the agency has met its initial burden of proof to show that undisclosed records fall within a discretionary exception under Section 4(b), the burden shifts to the complaining party to demonstrate that the agency’s denial of his access to those records was “arbitrary and capricious.” I.C. § 5-14-3-9(g).
Because the trial court’s review of the agency action was, as a matter of law, de novo, and because the only evidence presented to the trial court here were paper records, we are in just as good a position on appeal as the trial court was to consider the merits of Groth’s complaint. Accordingly, our review of the trial court’s judgment is de novo. E.g., Anderson v. Wayne Post 64, Am. Legion Corp., 4 N.E.3d 1200, 1206 (Ind. Ct. App. 2014), trans. denied. We disagree with the Governor’s argument on appeal that we must defer to the trial court’s assessment of the meaning of paper records when that assessment follows from an in camera review. Cf. id. (holding that we review a paper record de novo).
*1113[12] The Governor also asserts that we have no authority to conduct our own in camera review of sealed documents. Again, we disagree. Among other reasons, Article 7, Section 6 of the Indiana Constitution guarantees the right to one appeal. The Governor’s argument would render that right illusory where, as here, the merits of an appeal turn wholly on documents reviewed in camera by a trial court. On appeal, we review the entire trial court record. Groth has requested in camera review on appeal of the documents at issue, and to give effect to his right to an appeal, we have, by separate order, granted his request. However, we agree with the Governor that those documents shall remain excluded from public access pursuant to Indiana Appellate Rule 23(F)(2) and Indiana Administrative Rule 9(G).
Issue One: Justiciability of APRA Requests to the Governor
We first consider the Governor’s argument on appeal that Groth’s APRA complaint is not justiciable. As the Indiana Supreme Court has explained:
justiciability is not a question of jurisdiction, but whether it is prudent for the Court to exercise its jurisdiction....
The Indiana Constitution explicitly provides for the separation of powers: “The powers of the Government are divided into three separate departments; the Legislative, the Executive including the Administrative, and the Judicial; and no person, charged with official duties under one of these departments, shall exercise any of the functions of another, except as in this Constitution expressly provided.” Article 3, § 1. “[Although the courts have jurisdiction to review [a] case in the first instance, justiciability concerns stemming from Article 3, Section 1, caution courts to intervene only where doing so would not upset the balance of the separation of powers.” Berry [v. Crawford], 990 N.E.2d [410,] 418 [ (Ind. 2013) ]. In other words, although this Court may have, subject matter jurisdiction, it may, “for • prudential reasons,” ultimately conclude that the issue presented is non-justiciable. Id. “[W]here a particular function has been expressly delegated to the legislature by our Constitution without any express constitutional limitation or qualification, disputes arising in the exercise of such functions are inappropriate for judicial resolution.” Id. at 421.
Citizens Action Coalition, 51 N.E.3d at 240-41.
The Governor asserts that Citizens Action Coalition applies here. In that case, the Indiana Supreme Court considered whether the legislative “work product” exception to APRA’s disclosure rules was justiciable. Specifically, in Citizens Action Coalition the plaintiffs requested correspondence . that Eric Koch, a member, of the Indiana House of Representatives, or his staff, had sent to or received from business organizations with respect to specific legislation. Acting on Representative Koch’s behalf, the Indiana House Republican Caucus denied the requests because, in relevant part, APRA expressly “exceptfs]” from disclosure “at the discretion of a public agency”, the “work product of individual members and the partisan staffs of the general assembly.” I.C. § 5-14-3-4(b)(14).
The Indiana Supreme Court held that it would not be prudent for an Indiana court to define the “work product” of a member of the General Assembly or his partisan staff under Section 4(b)(14), and, therefore, it dismissed the appeal as not justiciable. Citizens Action Coalition, 51 N.E.3d at 241-43. Specifically, the court stated:
To maintain the separation of powers, this Court “should not intermeddle with the internal functions of either the Executive or Legislative branches of Govern*1114ment.” [State ex rel.] Masariu [v. Marion Sup. Ct. No. 1], 621 N.E.2d [1097,] 1098 [ (Ind. 1993)7].
This Court has previously found a separation of powers issue where legislation appears to empower the judicial branch to “inquire into and interfere with the internal operations of the Indiana House of Representatives.” Id. We determine that a similar type of inquiry and interference with the internal operations of the legislative branch is being requested in the present case.
APRA provides that “[a]ny person may inspect and copy the public records of any public agency during the regular business hours of the agency, except as provided in section 4 of this chapter.” Ind. Code § 5-14-3-3(a)....
[[Image here]]
The determinative issue in relation to justiciability arises instead under Defendants’ assertion that even if APRA is applicable, the requested documents are exempt from disclosure under APRA. As stated above, Indiana Code section 5-14-3-4(b) provides in pertinent part that “the following public records shall be excepted from section 3 of this chapter at the discretion of a public agency ... The work product of individual members and partisan staff of the general assembly.” The term “work product” is not defined within APRA nor by rule. Thus, the question becomes whether, under the principles of justiciability, this Court should define legislative “work product” and order the legislature to disclose records in accordance with this court-created definition. This we will not do.
[[Image here]]
Under Article 4, Section 16 of the Indiana Constitution, “[ejach House shall have all powers, necessary for a branch of the Legislative department of a free and independent State.” The General Assembly itself carries out those powers delegated to the legislative branch under Article 4, Section 16. Consequently, only the General Assembly can properly define what work product may be produced while engaging in its constitutionally provided duties. Thus, defining work product falls squarely within a “core legislative function.” Moreover, the General Assembly exercised its constitutional law-making authority when it crafted Section 4(b) of APRA, which provides that legislative work product “shall be excepted ... at the discretion of a public agency.” Ind. Code § 5-14-3-4(b) (emphasis added). Since the General Assembly and its members constitute a “public agency,” the statute itself expressly reserves to the General Assembly the discretion to disclose or not to disclose its work product. We are not inclined to make determinations that may interfere with the General Assembly’s exercise of discretion under APRA.
We hold that determining whether the documents requested by Plaintiffs are excepted under APRA as legislative work product presents a non-justiciable question.
*1115Id. at 241-43 (emphasis added; footnote omitted; some alterations original).
Relying on Citizens Action Coalition, the Governor asserts as follows:
The question of whether Groth’s specific APRA requests at issue are exempt from disclosure is not justiciable. Judicial inquiry into what documents the Governor chose to withhold from Groth in responding to his specific requests about Indiana’s challenge to President Obama’s actions constitute intermed-dling with the internal functions of the executive branch ....
[[Image here]]
Groth’s requests seek inquiry into core executive functions reserved to the Governor ....
... Groth now seeks judicial enforcement of his APRA requests, asking that the judicial branch interfere with these core functions expressly delegated to the Governor.
Appellee’s Br. at 30-31. Thus, the Governor contends that his ■ “own determinations” under APRA are conclusive and that it would violate the separation of powers doctrine for the judiciary to “second guess” those determinations. Id. at-32-33. We cannot agree.
This case is not & challenge to the Governor’s core executive functions or his constitutional authority as chief executive to decide whether Indiana should join Texas ■ and other states as a plaintiff in a federal suit against the President. Rather, the APRA requests here are merely requests for access to public records that concern a matter of legitimate public interest. On the issue of justiciability, the Governor does not assert a particular statutory exemption from APRA but, rather, makes a categorical claim of executive privilege from disclosure of his public records under APRA. The Governor’s argument would, in effect, render APRA meaningless as applied to him and his staff. APRA does not provide for any such absolute privilege, and the separation of powers doctrine does not require it. We reject the Governor’s assertion that his “own determinations” regarding whether to disclose public records are not subject to judicial review. See id.
Moreover, Citizens Action Coalition does not apply to APRA requests to the Governor for several additional reasons. First, the statutory exception at issue in Citizens Action Coalition applies only to the General Assembly. See I.C. § 5-14-3-4(b)(14). The Governor, obviously, did not rely on and could not have relied on that provision in making his response to Groth’s APRA request. Second, there is no statutory exception within APRA that is a “Governor’s version” of Section 4(b)(14). That is, there is no statutory counterpart to the legislative work product exception that applies to the Governor or his staff. See generally I.C. § 5-14-3-4(a), (b). Thus, there is no APRA exception on which the Governor could rely that might plausibly be captured by the holding in Citizens Action Coalition. Indeed, at oral argument, counsel for the Governor acknowledged that there is no text to be found in APRA that exempts the Governor from an APRA request.
The exceptions relied on by the Governor in his response to Groth relate to privileged attorney-client communications, attorney-client work product, and deliberative material. See I.C. § 5-14-3-4(a)(l), (a)(8), (b)(2), and (b)(6). To determine the meaning and apply those exceptions to an APRA request does not interfere with a core executive function. When APRA is correctly administered, the Governor’s prerogatives as the State’s chief executive remain intact.
Unlike the legislative work product exception at issue in Citizens Action Coalition, the interpretation and application of *1116the provisions at issue here do not present novel legal questions. See Citizens Action Coalition, 51 N.E.3d at 242. Indiana case law readily defines privileged attorney communications. E.g., Corll v. Edward D. Jones & Co., 646 N.E.2d 721, 724 (Ind. Ct. App. 1995). APRA expressly defines “[w]ork product of an attorney,” as used in Section 4(b)(2). I.C. § 5-14-3-2(r). And our courts have already defined and applied the term “deliberative material” as used in Section 4(b)(6). E.g., An Unincorporated Operating Div. of Ind. Newspapers, Inc. v. The Trustees of Ind. Univ., 787 N.E.2d 893, 909-15 (Ind. Ct. App. 2003), trans. denied.
The Governor asks that we disregard those definitions in APRA and our case law and, instead, apply Citizens Action Coalition to him and his staff, abstain from considering the questions presented in this appeal on the merits, and hold that “Groth does not present a justiciable issue.” Appellee’s Br. at 33. Again, in Citizens Action Coalition, on prudential grounds the Indiana Supreme Court invoked the separation of powers doctrine when it declined to impose a “court-created definition” of the “work product of the individual members and the partisan staffs of the general assembly.” 51 N.E.3d at 242. The court concluded that Section 4(b) of APRA “expressly reserves to the General Assembly the discretion to disclose or not to disclose its work product.” Id. But the court also held that APRA does apply to the General Assembly and its members'. Id. And the court did not hold that a person’s APRA requests to a co-equal branch of government are not justiciable. Thus, we conclude that Citizens Action Coalition, which concerns a provision that applies only to the legislature, does not apply to the Governor and his staff and that the separation of powers doctrine does not require that we abstain from deciding this appeal on the merits. The questions presented in this appeal are jus-ticiable, and to determine the answers to those questions we need only apply APRA to the facts.
Issue Two: Due Process
We next consider Groth’s argument on appeal that the trial court’s refusal to provide a summary of the undisclosed information, after the court had reviewed that information in camera, denied him his right to due process. In particular, Groth asserts that his opportunity to meet his burden to demonstrate that the Governor had failed to comply with APRA “is necessarily hampered, by his inability to see what the particular item is.” Appellant’s Br. at 18-19. In light of that concern, Groth requested that the trial court, following its in camera review, describe “the general nature of the information with enough specificity to alert the parties to what type of information is redacted” so that Groth could “make arguments [regarding] whether that type of information is required to be disclosed under the public records laws.” Appellant’s App. Vol. 2 at 32.
We agree with the Governor that Groth’s düe process rights were not implicated by the trial court’s judgment.8 The Indiana Supreme Court has considered and rejected a claim similar to Groth’s before. Specifically, the Indiana Supreme Court has stated as follows:
As for the State’s claim that it has not been afforded the opportunity to review the privileged documents to determine if *1117they contain non-privileged information, we conclude the State is not entitled to review the documents. And this is so because the very nature of the psychologist/patient privilege precludes the State from gaining access to confidential communications absent an exception. Rather, a determination must be made in the first instance as to whether the State has a right of access to the documents. Allowing the State itself to review the documents in order to make that determination would eviscerate the reason the privilege exists in the first place, namely: to protect confidential communications between psychologists and patients.
In essence we entrust tidal courts rather than sparring litigants with the authority to preserve the inviolability of privileged information. And although the trial court may have allowed the State to review the requested documents in this case under a confidential protective order, it was not compelled to do so. Further, the notion of a trial court conducting an in camera inspection of documents to determine whether information contained in them is or is not discoverable is not particularly remarkable. For example in Owen v. Owen, 563 N.E.2d 605 (Ind. 1990), we addressed the physician/patient privilege declaring:
[I]n those rare cases where the physician-patient privilege is properly invoked, it is incumbent on the party seeking to assert the privilege to identify to the court specifically which documents are believed to remain within the privilege, after which the court will review the contested documents in camera to ascertain their entitlement to the protection of the privilege.
Id. at 608 (emphasis added). In sum, the State has not shown any entitlement to review the contested documents, and the trial court did not abuse its discretion by conducting the, in camera inspection.
State v. Pelley, 828 N.E.2d 915, 920-21 (Ind. 2005) (some citations omitted).
In other words, Pelley rejects an argument similar to Groth’s and holds that the purpose of in camera review is for the court to determine independently whether certain information should be disclosed to an opposing party. Id. Groth could have requested the trial court to permit him to view the sealed records under a confidential protective order, which the trial court in its discretion may or may not have allowed, see id. at 921, but he did not make such a request. He cannot avoid his forfeiture of that opportunity by claiming a due process violation. The fundamental requirement of due process is the opportunity to be heard “at a meaningful time and in a meaningful manner.” Mathews v. Eldridge, 424 U.S. 319, 333, 96 S.Ct. 893, 47 L.Ed.2d 18 (1976). Groth has not shovm that he did not have an opportunity to be heard at a meaningful time and in a meaningful manner. Accordingly, we reject Groth’s argument that the trial court’s judgment violated his due process rights.
Issue Three: White Paper
We now turn to the substance-of the Governor’s APRA decisions. We first consider whether the Governor properly withheld disclosure of the white paper that was attached to the email from Hodge, the chief of staff to the Governor-Elect of Texas, which Hodge sent to Governor Pence’s office and to numerous other governors’ offices throughout the United States. The Governor withheld this document under Indiana Code Sections 5-14-3-4(a)(l) and (a)(8), as a privileged attorney-client communication; Indiana Code Section 5-14-3-4(b)(2), as attorney work product; and Indiana Code Section 5-14-3-4(b)(6), as deliberative material.. We agree with the *1118Governor that the white paper was a privileged attorney-client communication and, also, that the Governor acted within his discretion when he withheld the white paper as deliberative material.9
Pursuant to APRA, “[t]he following public records are excepted from section 3 of this chapter and may not be disclosed ...: (1) Those declared confidential by state statute.... (8) Those declared confidential by or under rules adopted by the supreme court of Indiana.” I.C. § 3-14-3-4(a) (emphasis added). Communications that fall within the attorney-client privilege are confidential under state law and the rules of the Indiana Supreme Court. As then-Chief Justice Shepard explained:
the rationale underlying the attorney-client privilege supports its application to state agencies and their attorneys. The privilege protects those in need of legal services by providing for complete and confidential information to an attorney so the attorney may be fully advised in serving the client while assuring the client that these confidences will not be revealed. Colman v. Heidenreich (1978), 269 Ind. 419, 381 N.E.2d 866. A state agency has the same need for confidential legal advice.
* * *
This privilege is not defeated by the requirement of open public records. Generally, any person may inspect the public records of any public agency. Ind. Code § 5-14-3-3(a) (Burns 1987 Repl.). The legislature has created an exception to this rule for records declared confidential by statute or by Supreme Court rule. Ind. Code § 5-14-3-4(a)(l), (8). Privileged communications between attorney and client are protected by both. Ind. Code § 34-1-14-5 [now I.C. § 34-46-3-1] renders attorneys incompetent to testify as to confidential communications made to them in the course of their professional business. This statute is the codification of the attorney-client privilege. Key v. State (1956), 235 Ind. 172, 132 N.E.2d 143 (construing the predecessor statute, § 2-1714 (Burns 1946 Repl.)). An attorney also has a statutory duty to preserve the confidences and secrets of his client. Ind. Code § 34-1-60-4 [now I.C. § 33-43-1-3(5)]. This is a further codification of the privilege. Colman, 269 Ind. at 422, 381 N.E.2d at 868. Additionally, privileged communications are excluded from discovery by Trial Rule 26(B)(1), Ind. Rules of Procedure. Thus, a privileged communication between attorney and client is exempt from public inspection because it is declared confidential by statute and Supreme Court rule.
When a client seeks advice from an attorney in his professional capacity, the communication between attorney and client within the scope of the professional relationship should be treated as strictly confidential. This privilege applies to all communications made to an attorney for the purpose of professional advice or aid, regardless of any pending or expected litigation. Colman, 269 Ind. at 423, 381 N.E.2d at 869.
Ind. State Highway Comm’n v. Morris, 528 N.E.2d 468, 474-75 (Ind. 1988) (Shepard, C.J., concurring) (footnote omitted).
The attorney-client privilege “applies to all communications between the client and his attorney for the purpose of obtaining legal advice or aid regarding the Ghent’s rights and liabilities.” Corll, 646 N.E.2d at 724. A person asserting the privilege must show that “(1) an attorney-client relationship existed and (2) a confidential communication was involved.” Id. “Minimally, meeting this bur*1119den entails establishing that ‘the communication at issue occurred in the course of an effort to obtain legal advice or aid, on the subject of the client’s rights or liabilities, from a professional legal advisor acting in his or her capacity as such.’” TP Orthodontics, Inc. v. Kesling, 15 N.E.3d 985, 995-96 (Ind. 2014) (quoting Mayberry v. State, 670 N.E.2d 1262, 1266 (Ind. 1996)). Again, the Governor carried the initial burden in the trial court to show that the white paper fell within the attorney-client privilege and was, therefore, not subject to disclosure pursuant to Section 4(a). I.C. § 5-14-3-9(f).
The white paper is a privileged attorney-client communication and is protected by the common interest privilege. As we have explained:
The common interest privilege is an extension of the attorney-client privilege. United States v. BDO Seidman, LLP, 492 F.3d 806, 815 (7th Cir. 2007). In effect, the common interest privilege extends the attorney-client privilege to otherwise nonconfidential communications between parties represented by separate attorneys. Id. The common interest privilege “treats all involved attorneys and clients as a single attorney-client unit, at least insofar as a common interest is pursued.” 2 Stephen A. Saltzberg, et al., Federal Rules of Evidence Manual 501-30 (10th ed. 2011). The privilege is an exception to the general rule that the attorney-client privilege is waived when privileged information is disclosed to a third party. BDO Seidman, 492 F.3d at 815; see Cavallaro v. United States, 284 F.3d 236, 250 (1st Cir. 2002).
The common interest privilege permits parties whose legal interests coincide to share privileged materials with one another in order to more effectively prosecute or defend their claims. Hunton & Williams v. U.S. Dep’t of Justice, 590 F.3d 272, 277 (4th Cir. 2010). The privilege has been recognized in cases for over a century. United States v. McPartlin, 595 F.2d 1321, 1336 (7th Cir. 1979). It applies in civil and criminal litigation, and even in purely transactional contexts. In re Teleglobe Commc’ns Corp., 493 F.3d 345, 364 (3rd Cir. 2007).
The privilege is limited to those communications made to further an ongoing joint enterprise with respect to a common legal interest. BDO Seidman, 492 F.3d at 816; see Hunydee v. United States, 355 F.2d 183, 185 (9th Cir. 1965) (statements to and among attorneys “should be privileged to the extent that they concern common issues and are intended to facilitate representation in possible subsequent proceedings”). It is fundamental that the privilege cannot be waived without the consent of all parties to the defense. John Morrell & Co. v. Local Union 304A of United Food & Commercial Workers, 913 F.2d 544, 556 (8th Cir. 1990).
Price v. Charles Brown Charitable Remainder Unitrust Trust, 27 N.E.3d 1168, 1173 (Ind. Ct. App. 2015) (emphases added), trans. denied.
In Corll, we held that the common interest privilege applied to attorneys’ communications to prospective co-plaintiffs. 646 N.E.2d at 724-25. As we stated:
there is no question that the purpose of each preliminary meeting [between plaintiffs’ attorneys and prospective co-plaintiffs] was to discuss a potential lawsuit .... Where, as here, a group of individuals meet with attorneys concerning potential litigation, and the purpose of that consultation is to provide legal advice regarding rights and liabilities, we conclude that any communications made in furtherance of that purpose are “confidential communications” between *1120attorney and client and carry with them an expectation of confidentiality.
Id. We further noted:
Whether or not any one [prospective client] had retained any of the attorneys prior to a specific meeting is of no consequence .... [T]he preliminary nature of the meetings does not remove the meetings from the scope of the attorney-client privilege. What is essential to the existence of the attorney-client privilege is the confidential relation of client and attorney, and not the pendency of litigation or payment of a fee.
Id. at 725 n.4. Thus, we concluded that, “[w]hen two or more persons, with a common interest in some legal problem, jointly consult an attorney, ‘their confidential communications with the attorney, though known to each other, will of course. be privileged in a controversy of either or both the clients with the outside world.’ ” Id. at 725 (quoting McCormick on Evidence § 91 (4th ed. 1992)).
As Hodge’s email explains, the white paper was drafted by a Texas deputy solicitor general on behalf of the State of Texas. Thereafter, Hodge circulated the white paper as a “follow-up” to a “Governors-Only meeting” in which the Governor-Elect of Texas had discussed with other governors that his state was “preparing a legal challenge to the President’s recent executive orders on immigration.” • Appellant’s App. Vol. 2 at 30. The Governor-Elect of Texas had discussed the proposed litigation with the other governors on the “hope ... that other states will join the State of Texas’ legal action ....” Id. And the attached white paper “outlined] the legal theories supporting [Texas’] legal challenge ....” Id.
Moreover, in another email disclosed by the Governor in response to Groth’s complaint, a reporter asked the Governor’s office “to follow up on the [G]overnor’s statement[10] about President Obama’s executive order on immigration.” Id. at 25. The reporter also asked if Governor Pence agreed with “some governors” in other states that the President’s order would “pose operational challenges for states, including whether to issue driver’s licenses to immigrants or grant in-state tuition.” Id. The reporter’s email to the Governor’s office was sent three days prior to Hodge’s email with the white paper attachment.
Governor Pence met his burden to show that the white paper was not subject to disclosure under APRA. There is no question that the Governor was aware of and disagreed with the President’s immigration orders. And, based on Hodge’s email to the Governor’s Chief of Staff, Jim Atterholt, the Governor was aware of the Governor’s-only meeting; he was aware that the State of Texas intended to “lead the charge” against the President’s orders in a federal lawsuit; he was aware that the State of Texas sought to collaborate with *1121other states to prosecute that legal challenge; and he recognized that the white paper had been distributed to assist likely co-plaintiffs in their decision whether to join the contemplated litigation. Further, it is clear that the white paper was created by a Texas deputy solicitor general on behalf of his client, the State of Texas. And, having reviewed the white paper in camera, we agree with the Governor that it is devoted to a discussion of legal theory and strategy to be used in the federal lawsuit.
Thus, we agree with the Governor that, “[i]n the case of the white paper, one party is sharing a legal memo, drafted by its lead counsel, with other potential parties in order to assist those parties in determining whether to join in the lawsuit.” Id. at 65. As such, the white paper was a communication made to further an ongoing joint enterprise with respect to a common legal interest. Price, 27 N.E.3d at 1173. Accordingly, we hold that the white paper was privileged attorney-client communication under the common interest doctrine. See Corll, 646 N.E.2d at 724-25. As promised by Texas Governor-Elect Abbott, Hodge sent the white paper to Governor Pence and other governors to explore their common interest in contesting the President’s executive orders. This communication of a legal opinion occurred as Texas sought to determine whether other states would agree to-join in the federal suit and, as a result, twenty-five states joined Texas as plaintiffs.11
Here, similar to Corll, a group of like-minded governors shared legal theories and strategies via email,to consider whether to join in litigation. 646 N.E.2d at 724-25. The purpose of that consultation was to provide legal advice to the prospective co-plaintiffs. See id. Thus, the communications made in furtherance of that purpose were confidential communications between attorney and clients and “carried] with them an expectation of confidentiality.” Id. As such, we conclude that the Governor met his burden to demonstrate that the white paper was a privileged communication and therefore exempt from disclosure under APRA. See I.C. § 5-14-3-4(a)(l), (8).
Nonetheless, Groth contends that the attorney-client privilege does not apply to the white paper for two reasons.12 First, Groth asserts that, at the time the Texas deputy solicitor general created the white paper, the State of Indiana was not his client. In other words, he characterizes the white paper as an “unsolicited email” or, stated another way, an uninvited solicitation from Texas’ lawyers. Reply Br. at 10; But no one suggests that the Governor would have employed the Texas deputy solicitor general to represent the State of Indiana in the federal lawsuit. And Groth’s solicitation theory is not supported by the record, which shows that the Governor and other governors knew of the President’s orders and Texas’’ plan to contest those orders and that they anticipated receiving additional information from Texas to consider in deciding whéther their states would become co-plaintiffs. The Hodge email with a legal memorandum attached was not the beginning but the continuation of a discussion already underway among the governors and, as such, was not an unsolicited email.
*1122Groth also asserts that the communication of the white paper to Governor Pence was not confidential because it was attached to an email that had been “sent to thirty recipients. The context of the [email] itself shows that the recipients were not clients of the author[ ] because it specifically discusses parties who may or may not have decided to join the lawsuit.” Id. at 15. In support of that argument, Groth relies on precedent from the Fourth Circuit Court of Appeals, which provides that the common interest privilege does not apply if a public agency is “simply considering whether to become involved” in litigation. Hunton & Williams, 590 F.3d at 274. But that is not the Indiana rule, which recognizes that the attorney-client privilege attaches to preliminary discussions between attorneys, prospective clients, and other potential parties who share a common interest concerning a potential lawsuit. Corll, 646 N.E.2d at 724-25. As we explained in Price, the common interest privilege “is an exception to the general rule that the attorney-client privilege is waived when privileged information is disclosed to a third party.” 27 N.E.3d at 1173. Indeed, the common interest privilege expressly “permits parties whose legal interests coincide to share privileged materials .... ” Id. And, again, under Corll, the fact that such information was shared with others who may or may not have decided to join the lawsuit does not vitiate the common interest privilege. Thus, we reject Groth’s arguments.
Because we hold that the Governor has met his burden to show that the white paper falls under Section 4(a) as privileged attorney-client communication, the Governor had no discretion to release the information. Rather, his nondisclosure of that document was mandatory. I.C. § 5-14-3-4(a). And we cannot agree with Groth’s arguments to the contrary.
We also agree with the Governor that he acted within his discretion when he withheld the white paper as deliberative material. Indiana Code Section 5-14-3-4(b)(6) permits a public agency, in its discretion, to withhold from disclosure “[r]ecords that are intra-agency or inter-agency advisory or deliberative material, including material developed by a private contractor under a contract with a public agency, that are expressions of opinion or are of a speculative nature, and that are communicated for the purpose of decision making.” As we have explained: “The purpose of protecting such communications is to prevent injury to the quality of agency decisions. The frank discussion of legal or policy matters in writing might be inhibited if the discussion were made public, and the decisions and policies formulated might be poorer as a result.” Unincorporated Operating Div. of Ind. Newspapers, 787 N.E.2d at 909-10 (citations, quotations, and footnote omitted).
Here, the white paper is a “paper ... received ... by ... a public agency” and is therefore a record under APRA I.C. § 5-14-3-2(o). The Governor used that record within his office, making it an intra-agency record. And the white paper was an expression of legal opinion used by the Governor for the purpose of decision making. Accordingly, the Governor acted within his discretion when he withheld the white paper under the deliberative material exception.
The burden thus shifted to Groth to demonstrate that the Governor’s denial was “arbitrary and capricious.” I.C. § 5-14-3-9(g). “An arbitrary and capricious decision is one which is ‘patently unreasonable’ and is ‘made without consideration of the facts and in total disregard of the circumstances and lacks any basis which might lead a reasonable person to the same conclusion.’ ” A.B. v. State, 949 *1123N.E.2d 1204, 1217 (Ind. 2011) (quoting City of Indianapolis v. Woods, 703 N.E.2d 1087, 1091 (Ind. Ct. App. 1998)). We are not persuaded by Groth’s argument that the Governor’s response was arbitrary and capricious. See I.C. § 5-14-3-9(g).
Thus, we affirm the trial court’s judgment for the Governor with respect to the white paper.
Issue Four: Law Firm Invoices
Finally, we turn to the Governor’s decision to redact the invoices of Barnes & Thornburg LLP, the private law firm the Governor had hired to represent Indiana and his office in the Texas litigation and on Groth’s APRA claim, respectively. The Governor redacted those invoices pursuant to Section 4(b)(2), which permits the Governor, “at [his] discretion,” to limit his production of requested public documents when such documents are “[t]he work product of an attorney representing ... a public agency[ or] the state
[[Image here]]
The Governor has met his burden to show that the information redacted from the legal invoices falls within the scope of Section 4(b)(2). Having reviewed the unre-dacted invoices in camera, we agree with the Governor that the redacted information refers to the attorneys’ research and legal opinions, theories, communications, or conclusions with respect to various aspects of litigation involving the State and the Governor. As such, the Governor acted within his discretion when he redacted that information from the invoices as the work product of attorneys representing the State of Indiana or the Governor.
The burden thus shifted to Groth to demonstrate that the Governor’s denial of full access to the invoices was “arbitrary and capricious.” I.C. § 5-14-3-9(g). Groth has not met that burden. Groth asserts that the Governor’s decision to redact the invoices was arbitrary and capricious because the attorney work product exception does not protect either information the Governor might have shared with third parties or factual information. But Groth cites no evidence that the Governor has shared the invoices with third parties. And, having reviewed the documents in camera, we reject Groth’s assertion that the Governor erroneously redacted information that is not attorney work product, as defined in Indiana Code Section 5-14-3-2(r). Accordingly, Groth has not met his burden of demonstrating that the Governor’s partial redaction of the legal invoices was arbitrary and capricious, and we affirm the trial court’s judgment for the Governor with respect to the legal invoices.
Conclusion
In sum, we reject the Governor’s claim that executive privilege renders his response to APRA requests immune from judicial review. We also reject Groth’s argument that the trial court’s judgment violated his due process rights. We affirm the trial court’s judgment for the Governor on the merits of the Governor’s decision to redact or withhold the records in question.
Affirmed.
Baker, J., concurs. Vaidik, C.J., concurs in part and dissents in part with separate opinion.. We held oral argument on November 21, 2016, in the Indiana Supreme Court courtroom. At that argument, counsel for Groth suggested that the Governor had partially redacted multiple emails he had submitted in response to the APRA request. It is clear on appeal, however, that the only issues raised regarding the Governor’s alleged noncompliance with APRA relate to the law firm invoices and the “white paper,” the latter of which was an attachment to an email received by the. Governor. The email to which the white paper was attached was released in full and is reproduced in material part below.
. Groth has included only eighteen pages of those documents in his appendix on appeal. Groth has also omitted from his appendix the Governor’s response to Groth’s complaint to the Public Access Counselor. And the Governor did not file an Appellee’s Appendix.
. Hodge sent the email to thirty different recipients, some of whom had state-based email addresses and some of whom did not. The recipients with clearly identifiable state-based email addresses were in the following twenty-six states: Alabama, Alaska, Arizona, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Maine, Michigan, Mississippi, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Wisconsin, and Wyoming.
. The Public Access Counselor is appointed by the Governor. I.C. § 5-14-4-6. The Public Access Counselor has the authority, among other things, to provide guidance to public agencies and officials regarding Indiana’s public access laws. I.C. § 5-14-4-10. This authority includes the power "[t]o issue advisory opinions to interpret public access laws Id. Advisory opinions, by definition, are "nonbinding statements.” Black's Law Dictionary 1265 (10th ed. 2014).
Our General Assembly created the Public Access -Counselor position to provide parties with efficient — but, correspondingly, nonbinding — advice regarding compliance with Indiana’s public access laws. In light of that purpose, a party "is not required to file a complaint” with the Public Access Counselor "before filing an action” in the trial court for an alleged violation of Indiana’s public access laws. I.C. § 5-14-5-4. As such, when a complaint is filed in a trial court after the Public Access Counselor has rendered an advisory opinion -on the matter, the court may find the Public Access Counselor's opinion persuasive but the court owes no deference to that opinion.
. The federal litigation that is- the subject of Groth's APRA complaint has already made its way through a United States District Court and United States Court of Appeals to, the United States Supreme Court and been remanded to the district court while we are only now addressing the APRA complaint. See United States v. Texas, — U.S.—, 136 S.Ct. 2271, 195 L.Ed.2d 638 (2016). Nonetheless, the complaint here raises a viable question that has not been obviated in the least by the legal proceedings in the federal forum.
. The Governor and his staff constitute a public agency under APRA. See I,C. § 5-14-3-2(n)(l). Also, we note that the 2016 version of Indiana Code Section 5-14-3-2 consists of two irreconcilable versions. But, as noted in paragraph 1, our citations to the Indiana Code are as it existed at the time Groth made his APRA request to the Governor at the end of 2014.
. The Governor also relies on Masariu, which is inapposite. In Masariu, the Indiana Supreme Court held that voting records of the Indiana House of Representatives were not subject to APRA or Indiana's Open Door Law because neither of those statutes "empower[s] the judicial branch to inquire into and interfere with the internal operations of the” House. 621 N.E.2d at 1098. More specifically, the court held that the power of the judiciary "cannot be authorized to undermine the exclusive constitutional authority of the presiding offices of each house to authenticate all legislation.” Id. The records requested of the Governor here are not analogous to the voting records of the members of the Indiana House of Representatives.
. The Governor also asserts that “the alleged violation of state law cannot form the basis of a due process claim." Appellee’s Br. at 28. But Groth does not assert that the trial court violated state law; Groth asserts that the trial court did not fully protect his due process rights.
. We need not discuss whether the attorney work product exception under Indiana Code Section 5-14-3-4(b)(2) applies to the white paper.
. The reporter’s inquiry was in response to a press release issued by the Governor. We take judicial notice that, in that press release, Governor Pence expressed his disagreement with the President's immigration decisions. Governor Pence Calls President's Executive Order ‘End Run Around Democratic Process' (Nov. 20, 2014), http://www.in.gov/activecalendar/ EventList.aspx?fromdate= 11/20/2014 & to-date^ 1/20/2014 & display=Day & type=public & eventidn= 195043 & view=EventDetails & informa-tion_id=208023; see also Ind. Evidence Rule 201(a), (d) (providing for judicial notice); Troyer v. Troyer, 987 N.E.2d 1130, 1138 n.3 (Ind. Ct. App. 2013) (noting that judicial notice may be taken on appeal), trans. denied. Indeed, the Governor's press release preceded Hodge’s email by five days, and, in that press release, the Governor stated that "[t]he State of Indiana will carefully evaluate the details of the Executive Order and take any available legal actions necessary to restore the rule of law and proper balance to our constitutional system of government.1' Governor Pence Calls President's Executive Order 'End Run Around Democratic Process’, supra.
. For the same reasons, the Governor asserts that the white paper is privileged attorney work product not subject to discovery pursuant to Indiana Trial Rule 26(B).
. Groth also asserts that, insofar as the white paper might contain factual recitations in addition to privileged information, those recitations are subject to disclosure. Having reviewed the white paper in camera, we agree with the trial court that no part of it is subject to disclosure. The facts mentioned in - the white paper are facts counsel considered significant and integral to the memorandum's legal analysis and opinion and, as such, are a privileged communication, ,
