Dillard, Chief Judge. In Smith v. Northside Hospital, Inc., 302 Ga. 517 (807 SE2d 909) (2017) (“Smith II“), the Supreme Court of Georgia reversed our previous decision in Smith v. Northside Hospital, Inc., 336 Ga. App. 843 (783 SE2d 480) (2016) (“Smith I“) and remanded the case with direction. Specifically, our Supreme Court reversed this Court’s holding affirming the trial court’s dismissal of E. Kendrick Smith’s action to compel Northside Hospital, Inc. and its parent company, Northside Health Services, Inc. (collectively, “Northside”) to provide him with access to certain documents in response to his request under the Georgia Open Records Act (the “Act”).[1] In doing so, the Supreme Court concluded that the trial court applied the wrong legal standard to the undisputed facts in finding the documents at issue were not public records within the meaning of the Act, and it remanded the case for the trial court to apply the correct legal standard, as set forth in Smith II, in determining whether the documents were public within the meaning of the Act; and if so, whether they may nevertheless be withheld under a statutory exception. Accordingly, we adopt the judgment of our Supreme Court, reverse the trial court’s dismissal of Smith’s action, and remand the case for further proceedings consistent with Smith II. But before doing so, we still have one other issue to address. Smith I involved cross-appeals, Case Nos. A15A2303 (i.e., Smith’s primary appeal) and A15A2304 (i.e., Northside’s cross-appeal), and the Supreme Court of Georgia, in Smith II, only addressed our decision in the primary appeal. In Smith I, we originally agreed with the trial court’s conclusion that the documents at issue were not public documents as a matter of law, and thus, we dismissed Northside’s cross-appeal, which challenged a pre-trial discovery ruling as moot. But given our Supreme Court’s reversal of Smith I, Northside’s cross-appeal is no longer moot, and we will now address it.[2]Specifically, Northside argues that the trial court abused its discretion by entering a protective order, prohibiting it from seeking information during discovery regarding the identity and motives of individuals or entities on whose behalf Smith allegedly initiated this action. We disagree. The facts and procedural history underlying Northside’s cross-appeal are essentially undisputed and are set forth in greater detail in Smith I and Smith II. But to summarize, the record shows that the Commissioners of Roads and Revenues of Fulton County passed a resolution in 1966, creating the Fulton County Hospital Authority (the “Authority”), which would “have and exercise all of the powers granted and prescribed in the Hospital Authority Laws.”[3] The purpose of creating the Authority was to improve and increase hospital facilities to serve the community.[4] To that end, the Authority opened Northside Hospital, which it owned and operated for approximately 25 years.[5] But in the early 1990s, recognizing “the rapidly changing healthcare environment in which it operated,” the Authority commissioned a study on the matter and ultimately determined that “the best way to improve the hospital’s performance was to restructure through a longterm lease of the hospital and related assets for operation by a private, charitable, nonprofit corporation.”[6] Thus, on November 1, 1991, the Authority executed a lease and transfer agreement (the “Agreement”) with the newly formed Northside Hospital, Inc., a private, nonprofit corporation.[7] Under the Agreement, the Authority leased the hospital facilities and transferred all of its “Operating Assets” and “Existing Operations” for a term of 40 years in exchange for a yearly rent payment of $100,000.[8] The leased facilities included the hospital, a surgery center, office buildings, and improvements.[9] Additionally, the Authority gave Northside the power to act on its behalf and operate the hospital subject to certain restrictions.[10] And each year since the Agreement was executed, the Authority reaffirmed its conclusion that its agreement with Northside promotes the public health needs of the community.[11] Particularly relevant to the instant dispute, Northside entered into transactions—between 2011 and 2013—to acquire four privately owned physician groups.[12] Smith learned of these transactions in 2013, and he sent a letter to Northside and the Authority, entitled “Open Records Request,” seeking access to financial statements and other documents related to the acquisitions.[13] In response, the Authority informed Smith that it did not possess any such documents, and Northside declined to comply with the request, contending that it was not subject to the Act because it was a private, nonprofit hospital.[14] Northside also notified Smith that, even if it were subject to the Act, the “highly sensitive” documents he requested would be statutorily exempt under several provisions of the Act, including the trade-secrets exception.[15]Thereafter, Smith—an Atlanta attorney—brought this action to compel Northside to reply with his open records request.[16] Discovery ensued, and on November 18, 2013, Northside sent Smith a letter, requesting the name of the client or clients who engaged him and his law firm to pursue this action. The next day, Smith declined the request, noting that the Act requires public records to be made available to “any person” who requests them. Thus, Smith contended that this matter was focused solely on Northside’s functions, its relationship with the Authority, and the documents in question, “not on anything concerning [him].” Nevertheless, on December 3, 2013, Northside sent Smith a notice of its intent to depose him on December 11, 2013. And rather than responding to the request, Smith filed a motion for a protective order to nullify Northside’s “improper deposition notice.” Specifically, Smith argued that the proposed deposition was irrelevant to the issues in the case because the Act makes public records available to anyone who requests them, and any individualized questioning of the requester is both unnecessary and inappropriate. Discovery continued and before the trial court ruled on his initial motion for a protective order regarding the deposition notice, Smith filed a second motion for a protective order, this time asking the court to prohibit any discovery regarding himself or the identity and purposes of his alleged clients. Following Northside’s response brief in opposition to the motion and a hearing on the matter, the trial court ultimately issued the protective order. Specifically, as requested, the court’s protective order prohibited “any discovery concerning [ ] Smith’s purposes in bringing [this] action, or the identity and purposes of any of his alleged clients.” Northside’s cross-appeal, challenging the propriety of that order, follows.[17] The grant or denial of a motion for protective order “lies within the sound discretion of the trial court, and we will reverse the court’s decision in this regard only when it has abused its discretion.”[18] This is because a trial court has broad discretion to control all discovery matters.[19] And as to protective orders, a trial court will only abuse its discretion when its ruling is “unsupported by any evidence of record or [when] that ruling misstates or misapplies the relevant law.”[20] That said, in Georgia, parties may obtain discovery regarding any matter, not privileged, “which is relevant to the subject matter involved in the pending action, whether it relates to the claim or defense of the party seeking discovery.”[21] With these guiding principles in mind, we will now address Northside’s claim of error. Specifically, Northside argues that the trial court abused its discretion by issuing the protective order, thus precluding discovery regarding the identity and purposes of Smith’s alleged client or clients, because doing so was contrary to Georgia law and the discovery sought is relevant to the Act’s trade-secrets exception.[22] We find this argument unavailing.In relevant part, OCGA § 50-18-71 (a) provides that “[a]ll public records shall be open for personal inspection and copying, except those which by order of a court of this state or by law are specifically exempted from disclosure.” And our General Assembly codified the public policy underlying the Act as follows: The General Assembly finds and declares that the strong public policy of this state is in favor of open government; that open government is essential to a free, open, and democratic society; and that public access to public records should be encouraged to foster confidence in government and so that the public can evaluate the expenditure of public funds and the efficient and proper functioning of its institutions. The General Assembly further finds and declares that there is a strong presumption that public records should be made available for public inspection without delay. This article shall be broadly construed to allow the inspection of governmental records. The exceptions set forth in this article, together with any other exception located elsewhere in the Code, shall be interpreted narrowly to exclude only those portions of records addressed by such exception.[23]Further, the Supreme Court of Georgia has held that the right of access afforded by the Act is a “public right of the People as a whole[,]” rather than a private right vested in any particular person.[24] Indeed, as acknowledged by our Supreme Court, “[t]he purpose of Georgia’s Open Records Act is to allow the public to evaluate the expenditure of public funds and to foster confidence in government through openness to the public.“[25] Given these codified public policy concerns, the Act “treats all public records as subject to disclosure, except those which by order of a court of this state or by law are prohibited or specifically exempted from being open to inspection.”[26] And as to actions for judicial enforcement of the Act, it provides that they “may be brought by any person, firm, corporation, or other entity.”[27] Moreover, the Act does not “limit the authority to commence an enforcement action to persons who had made a request for records or to persons with a special or personal interest in the requested records.”[28] Lastly, when an action to enforce the Act is brought, “the first inquiry is whether the records are ‘public records’”[29] as defined by the Act, and if so “the second inquiry is whether they are protected from public disclosure” under a statutory exception.[30]Here, Northside concedes that the identity and purposes of Smith’s client or clients have no bearing on whether he has standing to seek access to public documents via an open-records request. Indeed, the plain language of the Act provides that any person may bring an action to compel the disclosure of public records.[31] Nevertheless, Northside argues that it is entitled to discovery regarding those matters because the identity and purposes of Smith’s client—and whether the client is a competitor of Northside who is “pursuing this case to gain economic value and for competitive purposes—is potentially dispositive of whether the records sought by Smith are trade secrets that are exempt from disclosure.” Although decided in a somewhat different factual context, the Supreme Court of Georgia’s decision in Atchison v. Hospital Authority of City of St. Marys[32] is instructive in considering the issue before us. In Atchinson, the plaintiff, a Georgia resident, sought certain telephone records of a public entity for inspection under the Act.[33] But the trial court held that the records were not subject to inspection because the plaintiff was “only a nominal plaintiff acting in the real interest” of his employer, a Florida company.[34] The trial court further concluded that the Florida company, which was not a Georgia resident, was attempting to do, through its employee, that which it could not do for itself.[35] The Supreme Court of Georgia reversed, explaining that, in determining whether certain records are subject to inspection under the Act, “the judiciary must balance the interest of the public in favor of inspection against the interest of the public in favor of noninspection in deciding this issue.”[36] And in applying this balancing test, our Supreme Court held that prohibiting inspection of records under the Act must be based on “the nature of the information” sought, not the connections of the person seeking the information with a nonparty.[37] Indeed, the Act does “not limit the authority to commence an enforcement action to persons who had made a request for records or to persons with a special or personal interest in the requested records.”[38]Turning to the instant case, the trial court, in granting the protective order limiting discovery, found, consistent with Atchison, that “the intentions and motivations behind an Open Records Act request are irrelevant[.]” The court also noted its prior finding, in dismissing a counterclaim Northside filed against Smith, that given the codified purpose of the Act, “ permitting parties subject to [open records] requests to bring counterclaims regarding the motivation and purposes behind the requests for documents to such actions would have a chilling effect on citizens’ rights to inspect public documents and ultimately their right to an open Georgia government.”[39] Nevertheless, in an attempt to overcome Georgia’s strong, codified public policy in favor of open government and the presumption that public records should be made available to the public without delay,[40] Northside contends the protective order was contrary to Georgia law, which provides for a broad scope of permissible discovery. And Northside is correct that “[p]arties may obtain discovery regarding any matter, not privileged, which is relevant to the subject matter involved in the pending action including the identity of persons having knowledge of any discoverable matter.”[41] Moreover, is likewise true that “[i]t is within the trial court’s sound legal discretion to determine the permissible extent of discovery, keeping in mind that the discovery procedure is to be construed [forgivingly] in favor of supplying a party with the facts.”[42] Nevertheless, a trial court has “wide discretion in the entering of orders permitting or preventing the use of discovery which oppressive, unreasonable, unduly burdensome or expensive, harassing, harsh, insulting, annoying, embarrassing, incriminating, or directed to wholly irrelevant and immaterial or privileged matters . . . .”[43] Here, Northside complains that the trial court failed to acknowledge the forgiving standards “applicable to discovery and cross-examination[,]” and claims that the specific discovery it requested was relevant, in part, “to support its defenses and to test Smith’s credibility as a witness.” But as previously explained, Northside never argued to the trial court that it needed the requested discovery to challenge Smith’s credibility, and we do not consider arguments made for the first time on appeal.[44] And in any event, Northside fails to explain how Smith’s credibility as a witness or even his testimony in general is relevant to whether the records at issue are subject to disclosure under the Act.Northside also maintains that the discovery it seeks is relevant to its trade-secrets defense. In this regard, OCGA § 50-18-72 (a) (34) provides that “[p]ublic disclosure shall not be required for records that are . . . [a]ny trade secrets obtained from a person or business entity that are required by law, regulation, bid, or request for proposal to be submitted to an agency.” And OCGA § 10-1-761 (4) defines “trade secrets” asinformation, without regard to form, including, but not limited to, technical or nontechnical data, a formula, a pattern, a compilation, a program, a device, a method, a technique, a drawing, a process, financial data, financial plans, product plans, or a list of actual or potential customers or suppliers which is not commonly known by or available to the public and which information: (A) Derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and (B) Is the subject of efforts that are reasonable under the circumstances to maintain its secrecy. Further, whether a particular type of information “constitutes a trade secret is a question of fact.”[45]Northside does not dispute that, regardless of whether Smith requested the documents at issue and initiated this action on behalf of one of its competitors or solely on his own behalf, it is still required to prove that the documents requested qualify as trade secrets under OCGA § 10-1-761 (4). Indeed, even if Smith initiated this action solely on his own behalf, Northside, as the defendant, has the burden of presenting evidence sufficient to satisfy both prongs of OCGA § 10-1-761 (4) in order to establish that these documents are trade secrets and exempt from disclosure.[46] As to those statutory requirements, Northside argues that the identity and purposes of Smith’s alleged client, who Northside believes is one of its competitors, is “key” to demonstrating that the information at issue is (1) not commonly known, (2) derives economic value from not being disclosed, and (3) subject to reasonable efforts to maintain its secrecy. But even assuming Smith’s client is a competitor of Northside, that competitor could only provide evidence as to whether it has access to the information, not whether it is commonly known to the public. Further, as to whether the requested information derives economic value from not being disclosed, Northside conceded at the hearing on the motion for a protective order that it could establish its trade-secrets defense without obtaining discovery as to the identity and purposes of Smith’s client or clients.[47] Indeed, there is no requirement that a defendant present evidence regarding any particular competitor’s economic interest in the information sought in order to establish that the information itself constitutes a trade secret. Lastly, it is unclear how Northside could establish its own efforts to maintain the secrecy of the documents at issue based on information regarding an alleged competitor. Presumably, only Northside would have knowledge of its own efforts in this regard. In sum, while the Supreme Court’s decision in Atchison did not specifically involve any exceptions from disclosure under the Act, we find its reasoning persuasive, at least when the trade-secrets defense is asserted. This is because, regardless of the identity and purposes of any interested third party or nonparty competitor, the documents sought in an open-records request either contain trade secrets as defined by OCGA § 10-1-761 (4) or they do not. Thus, given the broad discretion a trial court has to control discovery matters; the minimal probative value, if any, of the identity and motives of Smith’s alleged clients; and Georgia’s strong, codified public policy in favor of open government as expressly promulgated by the General Assembly, we conclude that the trial court did not abuse its discretion in precluding Northside from seeking discovery regarding the identity and motives of Smith’s alleged client or clients.[48] For all these reasons, in Case No. A15A2304, we affirm the trial court’s grant of Smith’s motion for a protective order. Additionally, we remand Case No. A15A2303 for further proceedings consistent with the Supreme Court of Georgia’s decision in Smith II.Judgment affirmed in Case No. A15A2304 and reversed and remanded in Case No. A15A2303.
