T1 The legal controversy between Vande-lay Entertainment, LLC d.b.3. The Lost Ogle and Governor Mary Fallin stems from the Governor's refusal to release certain records in response to a request by Vandelay 1 pursu*1275ant to the Open Records Act, 51 0.8.2011 and Supp.2018, §§ 24A.1-24A.29. The material facts underlying this controversy are not in dispute.
{ 2 Vandelay asked Governor Fallin to release all records relating to her decisions regarding funding and programs under the Affordable Care Act. In responding to this request, Governor Fallin released over 51,000 pages of written material, but withheld 100 pages under a claim of "executive privilege." In a letter to Vandelay dated March 29, 2012, the Governor's general counsel explained: "In this document production, the Governor has invoked several legal privileges, including ones involving senior executive branch officials who are offering advice and counsel to the governor." (Emphasis added).
13 Vandelay filed suit in district court pursuant to § 2MA.17(B)(1)2 of the Oklahoma Open Records Act, to compel the Governor to release the records that were withheld. A copy of the March 29 letter from the Governor's general counsel was attached to Vandelay's petition. Vandelay disputed the Governor's claim of privilege, contending the withheld material was not specifically exempted from release by the Open Records Act, nor was it required to be kept confidential by any constitutional provision, statute, court decision or common law. In her answer, Governor Fallin acknowledged the March 29 letter and formally "invoked the doctrine of executive privilege with its deliberative process component" as a legal basis to withhold the material in question.
T4 The parties presented the case for decision on eross motions for summary judgment. Citing 12 0.98.2011, § 2,3 the district court ruled that Oklahoma had preserved common law to govern matters not otherwise addressed by the Oklahoma Constitution, statute or court decisions. The district court further ruled common law recognized a deliberative process privilege, but directed the Governor to submit a privilege log for judicial review to ensure the withheld material fell within the privilege.
T 5 Satisfied with the trial court's summary judgment recognizing her claim of privilege, Governor Fallin waived the privilege and released the 100 pages previously withheld. In doing so, the Governor filed a notice informing the court of the waiver and documents release. Copies of the particular documents were not filed in the record.
T6 Attached to this notice was a letter from the Governor's general counsel to Van-delay explaining the Governor's decision. This letter stated that the Governor's had theretofore acted (1) "To ensure that the Executive Privilege/Deliberative Process Privilege continue to be recognized in Oklahoma" and (2) "To ensure frank, candid and confidential discussions essential to the Governor's decision making remain confidential, because senior advisors need to present the Governor with conflicting ideas, thoughts and opinions without concern over the consequences that would follow from compelled public dissemination of their advice." (Emphasis added).
17 This letter further explained that "the passage of time since the deliberations took place has resulted in the deliberative advice becoming far less sensitive." The letter also *1276related that the Governor released the withheld documents out of concern for "transparency and openness in government" and "in consultation with many of those who provided the advice in the documents."
T8 Despite the release of the withheld material, Vandelay brought this appeal, contending the district court erred in recognizing a common law privilege exempting the Governor from complying with Vandelay's Open Records Act request. Because this issue is a matter of broad public interest and there is a likelihood of future repeated conflict between the Governor's claim of privilege and the Open Records Act, this Court finds Vandelay's appeal is not moot. State ex rel. Okla. Firefighters Pension v. City of Spencer, 2009 OK 73, 11 4-5, 237 P.3d 125, 129-130.
(T9 These same considerations dictate that this Court should retain this appeal for decision. Upon de novo review,4 we agree with the trial court that Oklahoma Governors have a privilege to refuse to disclose advice they receive in confidence from "senior executive branch officials" when deliberating discretionary decisions and shaping policy. We do so, however, on grounds different than those articulated by the trial court.
10 In looking to common law, the trial court was no doubt persuaded by City of Colorado Springs v. White, 967 P.2d 1042 (Colo.1998), cited in the Governor's summary judgment briefing. This Colorado case sets forth a thorough discussion of the common law origin and evolution of executive privilege in general and the deliberative process component in particular. Id. at 1047-58.
11 The Colorado opinion points out that executive privilege originated in the eighteenth and nineteenth centuries within the concept of the English "crown privilege." Id. at 1047. The opinion also notes that the deliberative process component of executive privilege is often referred to as "the common sense-common law privilege." Id. at 1048.
T 12 Having existed as an aspect of executive office prior to the adoption of the Oklahoma Constitution, we must conclude that the people at Statehood intended to preserve this common law privilege for the office of the Governor by the constitutional declaration, "The Supreme Executive power shall be vested in a Chief Magistrate, who shall be styled 'The Governor of the State of Oklahoma.'" Article 6, § 2 of the Oklahoma Constitution. In using the word "supreme" to modify the term "executive power," we believe the people intended to vest the Governor with the complete or full-range of executive powers that were recognized at the time the Oklahoma Constitution was adopted. In other words, executive privilege is not just a vestige of common law, but is an inherent power of the Governor.
1 18 In Ford v. Board of Tax-Roll Corrections, 1967 OK 90, T21, 481 P.2d 428. 428, this Court recognized that inherent powers are reflected in the separation of powers clause in Article 4, § 1 of the Oklahoma Constitution. This clause states "the Legislative, Executive and Judicial departments of government shall be separate and distinct, and neither shall exercise the powers properly belonging to either of the others." (Emphasis supplied by the Ford opinion). Id. at 15, 481 P.2d at 427. While the Ford case dealt with a question concerning the inherent power of the judicial branch, the principles and analysis this Court applied in recognizing the inherent power of the judiciary are the same for recognizing and protecting the inherent powers of the other coequal branches.
114 In Ford, this Court concluded the "powers properly belonging" to a branch of government were those "which [are] essential to the existence, dignity and functions [of the branch]" and include inherent powers. Id. at 1 21, 481 P.2d at 428 (citation omitted). One test for inherent power is whether the subject matter is "so ultimately connected and bound up with [a branch's function] that the right to define and regulate [the subject *1277matter] naturally and logically belongs to the [branch of government]." Id. Governor Fal-lin's claim of executive privilege to protect confidential advice from "senior executive branch officials" meets this test.
'I 15 Several provisions in the Constitution addressing the express powers of the Governor reflect that the Governor has discretion in exercising those powers. Article 6, § 6 provides "The Governor [as] Commander-in Chief of the militia of the State ... may call out the same to execute the laws, protect the public health, suppress insurrection, and repel invasion." (Emphasis added). Article 6, § 7 states "The Governor shall have power to convoke the Legislature ... on extraordinary sessions [to consider subjects] as the Governor may recommend for consideration." (Emphasis added). Article 6, § 9 declares "At every session of the Legislature ... the Governor shall communicate by message ... and shall recommend such matters to the Legislature as he [or she] shall judge expedient [and] communicate ... such matters as he [or shel may elect...." (Emphasis added). Article 6, § 10 provides "The Governor shall have power to grant ... commutations, pardons and paroles ... upon such conditions and with such restrictions and limitations as [the Governor] may deem proper...." (Emphasis added). Furthermore, the exercise of discretion is clearly implied in the general veto power, Article 6, § 11; the line item veto for appropriation bills, Article 6, § 12; and the appointment power, Article 6, § 18.
116 In addition, statutory law also gives the Governor discretion to do certain acts. For example, 74 0.9.2011, § 2 provides "The Governor shall have the power to remove any officers appointed by him [or her] ... and may then fill the same as provided in cases of vacancy." (Emphasis added). 74 0.8. 2011, § 5 states "Whenever the Governor is satisfied that any crime has been committed within the state, and that the person charged therewith has not been arrested, or has escaped therefrom, in his [or her] discretion he [or she] may offer a reward ... for the arrest and delivery ... of the person so charged...." (Emphasis added). 74 O.8. 2011, § 7 declares "The Governor of the State of Oklahoma is hereby authorized, at the expense of the state, and within the limitations of the appropriation ... to maintain in such manner as the governor deems necessary and appropriate, the mansion provided for his [or her] cccupancy by the State of Oklahoma and to pay all expenses connected with said occupancy." (Emphasis added).
1 17 The sheer number, diversity and magnitude of discretionary decisions entrusted to the Governor demonstrate the public interest is best served by the Governor seeking and receiving advice to aid in deliberations and decision-making. The United States Supreme Court has observed "[TJhose who assist [executive decision-makers] must be free to explore alternatives in the process of shaping policies and making decisions and to do so in a way many would be unwilling to express except privately." United States v. Nixon, 418 U.S. 688, 708, 94 S.Ct. 8090, 41 L.Ed.2d 1089 (1974)(superseded by statute on other grounds). The Court further observed that "[The confidentiality of [advisory] conversations and correspondence [is grounded in] the necessity for the protection of the public interest in candid, objective, and even blunt or harsh opinions in [executive] decisionmaking." Id.
$18 The United States Supreme Court concluded these "considerations justifly] a presumptive privilege." Id. The Court also concluded that such a privilege "is fundamental to the operation of Government and inextricably rooted in the separation of powers under the Constitution." Id; accord, Freedom Foundation v. Gregoire, 178 Wash.2d 686, 310 P.8d 1252, 1258 (2013) ("Refusal to recognize the gubernatorial communications privilege [to deny a legislatively authorized records request] would subvert the integrity of the governor's decision making process [thereby] damaging the functionality of the executive branch and transgressing the boundaries set by ... separation of powers.")
119 In considering Governor Fal-lin's claim of privilege in the case at hand, we agree with the United States Supreme Court's view that "complete candor and objectivity from advisers calls for great deference from the courts" in determining the *1278seope of executive privilege. 418 U.S. at 706, 94 S.Ct. 3090. An Oklahoma Governor has no less need than the President of the United States to receive "candid, objective, and even blunt or harsh opinions" provided by "senior executive branch officials" as well as the need to refuse to disclose such advice that was solicited or received confidentially.
120 This subject matter is so ultimately connected and bound up in the Governor's executive branch function that the right to regulate receipt and disclosure of such advice by way of a privilege naturally and logically belongs to the executive branch. Ford, T 21, 431 P.2d at 428. Stated another way, a privilege to protect confidential advice provided by "senior executive branch officials" is essential to the existence, dignity and functions of the Governor as chief executive and lies within the Governor's inherent power. Id. The principle of separation of powers expressly declared in Article 4, § 1 protects this privilege from encroachment by Legislative acts, such as the Open Records Act.
§21 Unlike the claim of absolute privilege considered in United States v. Niz-on, Governor Fallin has recognized that the deliberative process component of executive privilege that she claims in this case provides a qualified privilege. A qualified privilege is one that "applies in a particular instance if the purpose of the privilege is thereby served." City of Colorado Springs v. White, 967 P.2d at 1051. "The primary purpose of the [deliberative process] privilege is to protect the frank exchange of ideas and opinions critical to the government's decisionmaking [sic] processes where disclosure would discourage such discussion in the future[.]" Id.
122 A qualified privilege is also one in which the burden falls upon the government entity asserting the privilege. Id. at 1058. Had Governor Fallin not waived the privilege, she would have had the burden, upon in camera review, to demonstrate that the withheld documents fell within the privilege. Significantly, Governor Fallin's brief in support of her motion for summary judgment recognized this burden and requested the opportunity to demonstrate that the retained documents are protected by the deliberative process privilege.
€23 Based on the limited summary judgment record presented for review, we need not determine the full seope of the deliberative process component of executive privilege, but must only delineate the burden in cases of advice solicited or received from "senior executive branch officials." We leave for a more appropriate case the issue of whether the privilege extends to advice solicited from parties outside of state government.
124 The burden in cases involving advice from "senior executive branch officials" includes a showing that the advice was (1) pre-decisional, and (2) deliberative (Le., involved personal opinions, as opposed to purely factual, investigative material). Id. at 1052. In addition, the burden in the case at hand would also include a showing that (1) the Governor solicited or received advice from a "senior executive branch official" for use in deliberating policy or making a discretionary decision, (2) the Governor and the "senior executive branch official" knew or had a reasonable expectation that the advice was to remain confidential at the time it was provided to the Governor, and (8) the confidentiality of the advice was maintained by the Governor and the "senior executive branch official." While Governor Fallin did not define or specify whom she considers to be "senior executive branch officials," this group would reasonably include the Governor's general counsel and staff, the members of the Governor's cabinet, executive branch officers elected statewide, and executive branch agency heads appointed by the Governor.
125 Governor Fallin's answer and summary judgment briefing also acknowledged that the deliberative process privilege may even yield, when a substantial or compelling need for disclosure is shown. Onee the Governor establishes that a document satisfies the criteria above, the burden shifts to the party requesting a document to show (1) a substantial or compelling need for disclosure, and (2) this need for disclosure outweighs the public interest in maintaining the confidentiality of the executive communication. Id. at 1051. A cage in which there is *1279reason to believe that documents may shed light on government wrongdoing may present a substantial or compelling need for disclosure that would outweigh the need for confidentiality. Id.
126 In recognizing the deliberative process component of executive privilege, we are mindful that the Legislature enacted the Open Records Act to assist the people in their oversight of State government and to aid the people in the exercise of their inherent power to alter or reform their government. Article 2, § 1 of the Oklahoma Constitution. This Court has said that public access to government files (1) "permits checks against the arbitrary exercise of official power and secrecy in the political process," (2) "gives private citizens the ability to monitor the manner in which public officials discharge their public duties," and (8) "ensures [performance] in an honest, efficient, faithful, and competent manner." Oklahoma Public Employees Association v. State ex rel. Oklahoma Office of Personnel Management, 2011 OK 68, 1 36, 267 P.3d 888, 851.
127 However, the deliberative process component of executive privilege is also grounded in a strong public interest. The Governor's need for confidential advice in deliberation of policy and decisionmaking is just as important to "[the people's] protection, security, and benefit, and to promote their general welfare," as the people's access to information. Article 2, § 1 of the Oklahoma Constitution.
128 By vesting the Governor with supreme executive power and delegating dis-eretionary decisionmaking authority to the Governor, we believe the people placed checks on their access to certain types of confidential advice the Governor considers, and on legislative power to mandate disclosure of such advice. In place of on demand disclosure, in camera review and judicial balancing of competing public interests provide a middle ground accommodation when there is a question over whether the privilege exists or should be enforced. These safeguards fully protect the public from abuse of the privilege, while shielding communications ultimately found to warrant protection from public disclosure.
29 In conclusion, we hold that the trial court correctly ruled that the Governor has a privilege to protect confidential advice solicited or received from "senior executive branch officials" for use in deliberating policy and making discretionary decisions. We disagree, however, with the trial court's conclusion that this privilege rests solely upon common law. We hold that this privilege is a "power properly belonging" to the Governor's constitutional office as head of the executive branch and is protected by the separation of powers clause in Article 4, § 1. The need for confidential advice from "senior executive branch officials" for use in the Governor's deliberations and decision-making is "essential to the existence, dignity and functions" of the executive branch. Also, the need to protect such confidential advice is so ultimately-congeected and bound up with the executive function that the right to regulate disclosure of such confidential advice by way of a privilege naturally and logically belongs to the executive branch.
30 This privilege is not absolute, however, and is subject to the check and balance of in camera judicial review, in lieu of legislatively-mandated public disclosure. The Governor has the burden upon in camera judicial review to demonstrate that any material relating to such confidential advice satisfies the criteria set forth in this opinion. Even confidential advice that satisfies this criteria can be subject to disclosure where (1) the requesting party can show a substantial or compelling need for disclosure and (2) the need for disclosure outweighs the public interest in maintaining the confidentiality of the advice.
