Boggs, Justice.
**252This case presents the first opportunity for this Court to consider the effects of the General Assembly's wholesale revision in 2016 of the anti-SLAPP statute, OCGA § 9-11-11.1, which now substantially mirrors California Code of Civil Procedure § 425.16. We vacate the trial court's denial of the defendants' anti-SLAPP motion at issue in this case, and we remand the case with direction to reconsider the motion under the proper standards.
LTC Consulting, L.P. and two affiliated entities sued law firm Wilkes & McHugh, *121P.A. and one of its attorneys for violations of OCGA § 31-7-3.2 (j), deceptive trade practices, and false advertising after the defendants ran full-page advertisements in local newspapers targeting patients of nursing homes owned by the plaintiffs. The defendants filed a Motion to Dismiss or to Strike Pursuant to OCGA §§ 9-11-11.1 and 9-11-12 (b) (6), arguing among other things that OCGA § 31-7-3.2 (j), which was enacted in 2015, violates the First Amendment. See Ga. L. 2015, p. 1315. The motion was filed the day before a previously scheduled injunction hearing, but the trial court considered the defendants' motion and denied it. The defendants appealed to the Court of Appeals, which properly transferred the case to this Court.
We conclude that the defendants met their burden under OCGA § 9-11-11.1 to show that the plaintiffs' claims are ones arising from acts that could reasonably be construed as acts in furtherance of the defendants' right of free speech under the United States Constitution in connection with an issue of public interest or concern, thereby triggering the application of OCGA § 9-11-11.1. The burden then shifted to the plaintiffs to establish that there was a probability that they would prevail on their claims. However, in analyzing these claims, the parties did not argue, and the trial court did not properly apply, the new standards for anti-SLAPP motions explained in more detail below. In particular, the parties and the trial court overlooked certain preliminary questions, which also have not been adequately briefed here. We are reluctant to address these questions in the first **253instance without affording the trial court an opportunity to consider them with adequate briefing from the parties. Accordingly, we vacate the trial court's denial of the defendants' anti-SLAPP motion, and we remand the case with direction to reconsider the anti-SLAPP motion under the proper standards.
1. The defendants in this lawsuit are Wilkes & McHugh, P.A., a Florida-based law firm that focuses on suing nursing homes, and Gary Wimbish, an attorney with the firm who is licensed to practice law in Georgia. On October 11, 2017, the defendants ran a full-page advertisement in a Cobb County newspaper concerning a local nursing home, Bonterra Transitional Care and Rehabilitation ("Bonterra"). On October 12, 2017, they ran a similar ad in a Cobb County newspaper about another local nursing home, Powder Springs Transitional Care and Rehabilitation ("Powder Springs"). And on October 18, 2017, they ran a similar ad in a Rockdale County newspaper concerning a local nursing home, Rockdale Healthcare Center ("Rockdale Healthcare"), which is owned by LTC Consulting, L.P. Each ad referred to the results of one or more government "surveys," or inspections, of the nursing home named in the ad.1
(a) The Ads
All three ads had the same format. Each ad stated across the top in a large font and all capital letters, "THIS IS A LEGAL ADVERTISEMENT,"2 followed by a larger, reverse-background stripe stretching all the way across the page and containing the contrasting words "IMPORTANT NOTICE" in a still larger font. This stripe and the stripe described below are the most visually prominent features of the ads.
*122After the first stripe, the ads stated, in a large, bolded font, "If your loved one has been a resident at," followed by the name of the specified nursing home in an even larger font and in all capital letters.
**254The nursing home's street address appeared on the next line in a much smaller but still bolded font. Aside from the stripes, the nursing home's name was the most prominent feature of each ad. Each ad then stated in a large font: "This facility has been cited for multiple deficiencies* including," followed by three to ten paragraphs of text in a much smaller font that appeared in two columns in the Powder Springs and Bonterra ads and in a single column in the Rockdale Healthcare ad.
Each paragraph of subsequent text began with the word "FAILURE" - bolded, underlined, and in all capital letters - followed by text in regular type in a slightly smaller font that purported to recount the deficiencies for which each nursing home had been cited in a government survey conducted on one or more dates listed.3 The text also stated the date by which each deficiency was corrected and described the level of harm from each deficiency and the number of residents affected. After the listing of "FAILURES," the ads contained a densely worded paragraph stretching across the page and preceded by an asterisk - presumably referring back to the word "deficiencies*" above - that, among other things, said that the ads were not authorized or endorsed by any government agency, provided information on the survey process and average numbers of cited deficiencies at nursing homes in Georgia and in the United States, and listed a government website where those interested could find additional information.
Next, the ads contained another large, reverse-background stripe stretching all the way across the page. This stripe stated, in a large font and in all capital letters:
POOR CARE AND UNDERSTAFFING CAN LEAD TO: BEDSORES, CHOKING, FALLS, BROKEN BONES, DEHYDRATION, INFECTIONS/ SEPSIS, MALNUTRITION, OR UNEXPLAINED DEATH.
Below the stripe, each ad said, in a large, bolded font, "If someone you love has been a resident" of the named nursing home, "we would like to hear your story. Call or email our attorneys for a free consultation." The ads listed a telephone number, email address, and website for the law firm, included the firm's logo underneath, and then stated the law **255firm's street address in Tampa, Florida. At the end, each ad said in italics: "Gary Wimbish, Esq. is responsible for the content of this advertisement ."4
(b) The Trial Court Proceedings
On October 19, 2017, the owner of Powder Springs filed a Verified Complaint for Ex Parte Temporary Restraining Order and Preliminary and Permanent Injunctive Relief against the defendants, alleging that the ads violated OCGA § 31-7-3.2 's recently enacted subsection (j), which imposes limitations on advertisements that use or reference the results of federal or state surveys or inspections of nursing homes. The complaint also alleged violations of OCGA § 10-1-372 (a) (12), which is part of Georgia's Uniform Deceptive Trade Practices Act, as well as two false advertising statutes, OCGA §§ 10-1-421 (a) (untrue or fraudulent statements in advertisements for goods and services, including professional services) and 10-1-427 (a) (untrue, fraudulent, deceptive, or misleading statements in advertisements for legal services). Attached to the complaint were the ad concerning Powder Springs, one of the three surveys that the ad referenced, and a Scope and Severity Matrix for Nursing Home Deficiencies from the federal Centers for Medicare and Medicaid Services.5 At the same *123time, Powder Springs' owner filed a motion for an ex parte temporary restraining order ("TRO").
On the morning of October 20, 2017, the trial court granted the TRO. On the same day, Powder Springs' owner filed a First Amended Complaint for Ex Parte Temporary Restraining Order and Preliminary and Permanent Injunctive Relief, adding as plaintiffs the owners of Bonterra and Rockdale Healthcare and attaching as exhibits the defendants' ads concerning Bonterra and Rockdale Healthcare in addition to the ad concerning Powder Springs. The plaintiffs alleged that 91% of nursing homes surveyed are found to have "deficiencies" and that the defendants did not include in the ads all the information required by OCGA § 31-7-3.2 (j). The plaintiffs also alleged that each ad was false, fraudulent, deceptive, and misleading, both because each ad omitted facts necessary to make the ad not materially misleading when considered as a whole, and because each ad falsely implied that residents of the plaintiffs' nursing homes had suffered "BEDSORES," "BROKEN BONES," and **256"DEATH" from the cited deficiencies. The plaintiffs further alleged, among other things, that the Powder Springs ad falsely stated that four of the deficiencies "constituted minimal harm or the potential for actual harm," when in reality those four deficiencies were cited at the "D" level, meaning that there was no actual harm.
On the afternoon of October 20, 2017, the plaintiffs filed a motion for an expanded TRO, which the trial court granted. The expanded TRO enjoined the defendants from publishing or causing to be published in any newspaper or other media, including online: "any false, fraudulent, deceptive and misleading advertisements concerning the Plaintiffs"; "the advertisements included as Exhibits A, B, and C to Plaintiffs' [First] Amended Complaint"; and "any advertisements concerning the Plaintiffs that do not fully comply with the requirements of O.C.G.A. § 31-7-3.2 (j)." The expanded TRO was to remain in effect for 30 days or until November 10, 2017, when the court would hold a consolidated hearing on the plaintiffs' requests for preliminary and permanent injunctive relief.
On the day before the injunction hearing, the defendants filed a Motion to Dismiss or to Strike Pursuant to OCGA §§ 9-11-11.1 and 9-11-12 (b) (6), attaching as exhibits printouts from the Medicare.gov website concerning the surveys that the defendants cited in their ads. The defendants argued among other things that OCGA § 31-7-3.2 (j) violates the First Amendment and, in any event, that the ads substantially complied with the statute. At the hearing on November 10, 2017, the defendants contended that the trial court was required to hear their motion first, and the trial court did so. After the parties completed their arguments on the defendants' motion, the court took a brief recess before announcing that it would enter an order denying the defendants' motion. The court then adjourned the hearing to give the defendants' attorneys an opportunity to consult with their clients about taking an immediate appeal of the ruling on the motion. The defendants filed verified answers to the complaint later that month.
On November 30, 2017, the trial court entered an order denying the defendants' motion to strike. The court ruled that, even if the plaintiffs' claims arose from acts by the defendants that could reasonably be construed as in furtherance of their rights of petition or free speech in connection with an issue of public concern, the plaintiffs had established that there was a probability that they would prevail on their claims, thereby barring dismissal. The defendants then filed a timely notice of appeal directed to the Court of Appeals.
(c) The Appeal
After briefing and oral argument, the Court of Appeals on August 27, 2018, properly transferred the case to this Court based on the plaintiffs' First Amendment challenge to OCGA § 31-7-3.2 (j), which **257the trial court implicitly rejected in denying the defendants' motion.6 On October 2, 2018, the plaintiffs *124filed a motion to return the case to the Court of Appeals, which this Court denied on October 22, 2018. The parties then filed supplemental briefs addressing certain First Amendment issues, but only as to OCGA § 31-7-3.2 (j). The case was orally argued in this Court on January 22, 2019.
2. "Strategic lawsuits against public participation," or "SLAPPs,"7 are meritless lawsuits brought not to vindicate legally cognizable rights, but instead to deter or punish the exercise of constitutional rights of petition and free speech by tying up their target's resources and driving up the costs of litigation. To combat this practice, in 1996, the General Assembly added an anti-SLAPP provision to the Civil Practice Act, OCGA § 9-11-11.1. See Ga. L. 1996, p. 260, § 1 (codified as amended at OCGA § 9-11-11.1 ). In 2016, the General Assembly revised OCGA § 9-11-11.1 to substantially track California's anti-SLAPP procedure as set out in California Code of Civil Procedure § 425.16. See Ga. L. 2016, p. 341, § 2.
We have construed Georgia's anti-SLAPP statute a handful of times over the years since it was first enacted in 1996. See, e.g., EarthResources, LLC v. Morgan County , 281 Ga. 396, 638 S.E.2d 325 (2006) ; Denton v. Browns Mill Dev. Co. , 275 Ga. 2, 561 S.E.2d 431 (2002). For the most part, these cases have construed provisions of the anti-SLAPP statute that the 2016 amendment removed, see, e.g., Atlanta Humane Society v. Harkins , 278 Ga. 451, 452-454, 603 S.E.2d 289 (2004) (construing verification provisions of former OCGA § 9-11-11.1 (b) ), or they have interpreted language in the anti-SLAPP statute the meaning of which the 2016 amendment substantially changed, see, e.g., Berryhill v. Georgia Community Support & Solutions, Inc. , 281 Ga. 439, 439-443, 638 S.E.2d 278 (2006) (interpreting language in former OCGA § 9-11-11.1 (b) retained in current anti-SLAPP statute, but based on the two-part definition provided in former OCGA § 9-11-11.1 (c), which has now been expanded into a four-part definition); Denton , 275 Ga. at 4-7, 561 S.E.2d 431 (same). See also Neff v. McGee , 346 Ga. App. 522, 524 n.2, 816 S.E.2d 486 (2018) (noting that the 2016 amendment to OCGA § 9-11-11.1 expanded the scope of the **258anti-SLAPP statute); Rosser v. Clyatt , 348 Ga. App. 40, 42, 821 S.E.2d 140 (2018) (same). Moreover, the 2016 amendment fundamentally altered the mechanics of the anti-SLAPP procedure. Thus, our precedents construing the pre-amendment version of OCGA § 9-11-11.1 are of limited utility in interpreting the revised anti-SLAPP statute.
The California Supreme Court, by contrast, has developed a considerable body of case law interpreting the text of California Code of Civil Procedure § 425.16, which, as explained below, is very similar to the text of Georgia's revised anti-SLAPP statute. Thus, in interpreting our new OCGA § 9-11-11.1, we may look to California case law interpreting § 425.16 for guidance, especially decisions - such as the ones cited in this opinion - that employ the same kind of statutory analysis that we generally use. Cf., e.g., Chappuis v. Ortho Sport & Spine Physicians Savannah, LLC , 305 Ga. 401, 404 & n.4, 825 S.E.2d 206 (2019) (looking to Federal Rule of Civil Procedure 12 (f) and the federal decisions thereunder "to aid us in determining the purpose and meaning of" a provision of the Civil Practice Act modeled on the federal rule); Zaldivar v. Prickett , 297 Ga. 589, 598-600, 774 S.E.2d 688 (2015) (looking to decisions in other jurisdictions with similar apportionment statutes in interpreting Georgia's apportionment statute, including California, Colorado, Florida, Kansas, Michigan, New Hampshire, and Wyoming).8
(a) Georgia's Newly Revised Anti-SLAPP Statute
OCGA § 9-11-11.1 (a) declares that "it is in the public interest to encourage participation *125by the citizens of Georgia in matters of public significance and public interest through the exercise of their constitutional rights of petition and freedom of speech," and that "the valid exercise of the constitutional rights of petition and freedom of speech should not be chilled through abuse of the judicial process." Subsection (a) also provides that OCGA § 9-11-11.1 "shall be construed broadly" to accomplish these declarations. Accord Cal. Code Civ. Proc. § 425.16 (a) (same). The rest of OCGA § 9-11-11.1 concerns anti-SLAPP motions to strike a claim or to dismiss a complaint, which are usually, but not necessarily, filed by defendants against plaintiffs, as is the case here. Thus, the "moving party" is usually the defendant, and the "nonmoving party" is usually the plaintiff.
Subsection (b), which is now divided into three paragraphs, substantially changes the procedural mechanism from former **259OCGA § 9-11-11.1 for challenging SLAPPs at the outset of litigation.9 The first paragraph provides:
A claim for relief against a person or entity arising from any act of such person or entity which could reasonably be construed as an act in furtherance of the person's or entity's right of petition or free speech under the Constitution of the United States or the Constitution of the State of Georgia in connection with an issue of public interest or concern shall be subject to a motion to strike unless the court determines that the nonmoving party has established that there is a probability that the nonmoving party will prevail on the claim.
OCGA § 9-11-11.1 (b) (1). Accord Cal. Code Civ. Proc. § 425.16 (b) (1) (similar). The second paragraph provides, "In making the determination as provided for in paragraph (1) of this subsection, the court shall consider the pleadings and supporting and opposing affidavits stating the facts upon which the liability or defense is based. ..." OCGA § 9-11-11.1 (b) (2).10 Accord Cal. Code Civ. Proc. § 425.16 (b) (2) (similar).
The third paragraph of subsection (b) addresses later proceedings in the same case and in any subsequent case. It provides that a determination that the nonmoving party (usually, the plaintiff)
**260would prevail on a claim or the fact that such a determination was made is not admissible in evidence in any later stage of the case or in any subsequent proceeding, and that such a determination does not affect the burden or degree of proof otherwise applicable in any later stage of the case or in any subsequent proceeding. See OCGA § 9-11-11.1 (b) (3). Accord Cal. Code Civ. Proc. § 425.16 (b) (3) (similar). A new subsection, OCGA § 9-11-11.1 (b.1), requires the trial court to award "attorney's fees and expenses of litigation related to the action" to a moving party (usually, the defendant) who prevails on an anti-SLAPP motion, and to award "attorney's fees and expenses of litigation associated with the motion" to a nonmoving party (usually, the plaintiff) who *126prevails on an anti-SLAPP motion if the court finds that the motion was frivolous or solely intended to cause unnecessary delay. Accord Cal. Code Civ. Proc. § 425.16 (c) (1) (similar).
The General Assembly also substantially expanded the scope of the anti-SLAPP statute by adding paragraphs (3) and (4) at the end of subsection (c). This subsection, as revised, provides:
As used in this Code section, the term "act in furtherance of the person's or entity's right of petition or free speech under the Constitution of the United States or the Constitution of the State of Georgia in connection with an issue of public interest or concern" shall include:
(1) Any written or oral statement or writing or petition made before a legislative, executive, or judicial proceeding, or any other official proceeding authorized by law;
(2) Any written or oral statement or writing or petition made in connection with an issue under consideration or review by a legislative, executive, or judicial body, or any other official proceeding authorized by law;
(3) Any written or oral statement or writing or petition made in a place open to the public or a public forum in connection with an issue of public interest or concern; or
(4) Any other conduct in furtherance of the exercise of the constitutional right of petition or free speech in connection with a public issue or an issue of public concern.
OCGA § 9-11-11.1 (c) (1) - (4). Accord Cal. Code Civ. Proc. § 425.16 (e) (1) - (4) (similar).
**261The General Assembly left subsection (d) largely unchanged. It provides:
All discovery and any pending hearings or motions in the action shall be stayed upon the filing of a motion to dismiss or a motion to strike made pursuant to subsection (b) of this Code section until a final decision on the motion. The motion shall be heard not more than 30 days after service unless the emergency matters before the court require a later hearing. The court, on noticed motion and for good cause shown, may order that specified discovery or other hearings or motions be conducted notwithstanding this subsection.
OCGA § 9-11-11.1 (d). Accord Cal. Code Civ. Proc. § 425.16 (f), (g) (similar).11 But in a significant departure from prior practice, the 2016 revision added a new subsection (e), which authorizes an immediate appeal as of right from "[a]n order granting or denying" an anti-SLAPP motion. OCGA § 9-11-11.1 (e).12 See Grogan v. City of Dawsonville , 305 Ga. 79, 83-84, 823 S.E.2d 763 (2019). Accord Cal. Code Civ. Proc. § 425.16 (i). The remaining subsections of OCGA § 9-11-11.1 are not relevant to this appeal.13
(b) Georgia's New Anti-SLAPP Procedure
The text of OCGA § 9-11-11.1 (b) (1) makes clear that the analysis of an anti-SLAPP
*127motion involves two steps.14 First, the court must **262decide whether the party filing the anti-SLAPP motion (usually, the defendant) has made a threshold showing that the challenged claim is one "arising from" protected activity. OCGA § 9-11-11.1 (b) (1). See Navellier v. Sletten , 29 Cal.4th 82, 124 Cal.Rptr.2d 530, 52 P.3d 703, 708 (2002). It is not enough to show that the claim was filed "after protected activity took place" or "arguably may have been 'triggered' by protected activity." Id., 124 Cal.Rptr.2d 530, 52 P.3d at 708-709 (quoting City of Cotati v. Cashman , 29 Cal.4th 69, 124 Cal.Rptr.2d 519, 52 P.3d 695, 701 (2002) ). "[T]he critical consideration is whether the cause of action is based on the defendant's protected free speech or petitioning activity." Id. , 124 Cal.Rptr.2d 530, 52 P.3d at 709 (emphasis in original). A defendant meets its burden by demonstrating that the act underlying the challenged claim "could reasonably be construed as" fitting within one of the categories spelled out in subsection (c). OCGA § 9-11-11.1 (b) (1). See OCGA § 9-11-11.1 (c) (1) - (4) ; Navellier , 124 Cal.Rptr.2d 530, 52 P.3d at 708.
If a court concludes that this threshold showing has been made, it must proceed to the second step of the analysis and decide whether the plaintiff "has established that there is a probability that the [plaintiff] will prevail on the claim." OCGA § 9-11-11.1 (b) (1). To meet this burden, "the plaintiff must demonstrate that the complaint is both legally sufficient and supported by a sufficient prima facie showing of facts to sustain a favorable judgment if the evidence submitted by the plaintiff is credited." Soukup v. Law Offices of Herbert Hafif , 39 Cal.4th 260, 46 Cal.Rptr.3d 638, 139 P.3d 30, 51 (2006) (citation and punctuation omitted). See Taus v. Loftus , 40 Cal.4th 683, 54 Cal.Rptr.3d 775, 151 P.3d 1185, 1205 (2007) ("[P]ast cases interpreting [ California Code of Civil Procedure § 425.16 ] establish that the Legislature did not intend that a court, in ruling on a motion to strike under this statute, would weigh conflicting evidence to determine whether it is more probable than not that [the] plaintiff will prevail on the claim."); Briggs v. Eden Council for Hope & Opportunity , 19 Cal.4th 1106, 81 Cal.Rptr.2d 471, 969 P.2d 564, 575 (1999) (explaining that the second step "requir[es] the court to determine only if the plaintiff has stated and substantiated a legally sufficient claim" (citation and punctuation omitted)). See also RCO Legal, P.S., Inc. v. Johnson , 347 Ga. App. 661, 667 n.10, 820 S.E.2d 491 (2018) (holding, in case decided under current version of Georgia's anti-SLAPP statute, that " '[t]o satisfy the second prong, a plaintiff responding to an anti-SLAPP motion must state and substantiate a legally sufficient claim' " (quoting Oasis West Realty, LLC v. Goldman , 51 Cal.4th 811, 124 Cal.Rptr.3d 256, 250 P.3d 1115, 1120 (2011) ). "The plaintiff's evidence is accepted as true; the defendant's evidence is evaluated to determine if it defeats the plaintiff's showing as a matter of law." City of Montebello v. Vasquez , 1 Cal.5th 409, 205 Cal.Rptr.3d 499, 376 P.3d 624, 631 (2016).
Only a claim that satisfies "both prongs of the anti-SLAPP statute - i.e., that arises from protected [activity] and lacks even minimal **263merit - is a SLAPP" that is subject to being stricken. Navellier , 124 Cal.Rptr.2d 530, 52 P.3d at 708 (emphasis in original). See City of Montebello , 205 Cal.Rptr.3d 499, 376 P.3d at 631 ("The procedure is meant to prevent abusive SLAPP suits, while allowing claims with the requisite minimal merit to proceed." (citation and punctuation omitted)). Appellate review of an order granting or denying an anti-SLAPP motion is de novo. See RCO Legal , 347 Ga. App. at 661, 820 S.E.2d 491. See also Soukup , 46 Cal.Rptr.3d 638, 139 P.3d at 36 n.3.
3. As explained above, the first step of the anti-SLAPP analysis is to decide whether the party or parties filing the anti-SLAPP motion - here, the defendants - made a threshold showing that the plaintiffs' claims are ones "arising from" protected activity. OCGA § 9-11-11.1 (b) (1). See Navellier , 124 Cal.Rptr.2d 530, 52 P.3d at 709. Contrary to the plaintiffs' representations to this *128Court, the trial court did not decide that issue in the order under review here. Instead, the trial court assumed without deciding that the anti-SLAPP statute applied and rejected the defendants' anti-SLAPP motion at the second step of the analysis. In any event, we agree with the defendants that they met their burden to make a threshold showing that the plaintiffs' claims are ones arising from protected activity by demonstrating that the acts underlying the claims "could reasonably be construed as" fitting within at least one of the four categories spelled out in subsection (c). OCGA § 9-11-11.1 (b) (1). See Navellier , 124 Cal.Rptr.2d 530, 52 P.3d at 709.
OCGA § 9-11-11.1 (c) (4) refers to "[a]ny other conduct in furtherance of the exercise of the constitutional right of petition or free speech in connection with a public issue or an issue of public concern." The plaintiffs' claims that the defendants violated OCGA § 31-7-3.2 (j), the Uniform Deceptive Trade Practices Act, and the false advertising statutes are all based on the defendants' running of ads in local newspapers informing the public of the defendants' availability to provide legal services related to alleged serious injuries and even deaths at nursing homes in the area that resulted from deficiencies cited in government surveys. It is "well established that lawyer advertising is commercial speech and, as such, is accorded a measure of First Amendment protection." Florida Bar v. Went For It, Inc. , 515 U.S. 618, 623, 115 S.Ct. 2371, 132 L.Ed.2d 541 (1995). And the alleged existence of serious injuries and deaths at local nursing homes resulting from deficiencies known to a government agency certainly qualifies as a public issue or an issue of public concern. See generally FilmOn.com Inc. v. DoubleVerify, Inc. , 7 Cal.5th 133, 246 Cal.Rptr.3d 591, 439 P.3d 1156 (2019) (discussing analogous catchall provision of California's anti-SLAPP statute). Thus, running the ads could reasonably be construed as an act in furtherance of the defendants' constitutional right of free speech in connection with a public issue or an issue of public concern, see OCGA § 9-11-11.1 (c) (4), and the **264defendants therefore met their burden of making a threshold showing that the plaintiffs' claims are ones arising from protected activity.15
4. The second step of the anti-SLAPP analysis requires a determination of whether the party or parties opposing the anti-SLAPP motion - here, the plaintiffs - have established that there is a probability that they will prevail on their claims that the defendants violated OCGA § 31-7-3.2 (j), the UDTPA, and the false advertising statutes. See OCGA § 9-11-11.1 (b) (1). To meet this burden, the plaintiffs were required to demonstrate that their claims are both legally sufficient and supported by a sufficient prima facie showing of facts to sustain a favorable judgment if their evidence is credited. See Soukup , 46 Cal.Rptr.3d 638, 139 P.3d at 51 ; Briggs , 81 Cal.Rptr.2d 471, 969 P.2d at 574-575. In deciding whether the plaintiffs met their burden, the plaintiffs' evidence as to each claim is accepted as true, and the defendants' evidence is evaluated only to determine if it defeats the plaintiffs' showing as a matter of law. See City of Montebello , 205 Cal.Rptr.3d 499, 376 P.3d at 631.
As noted above, the trial court concluded that the plaintiffs met their burden at the second step of the anti-SLAPP analysis and therefore denied the defendants' anti-SLAPP motion. The court quoted the relevant part of OCGA § 9-11-11.1 (b) (1) and then explained its reasoning only as follows:
Here, Plaintiffs have demonstrated a probability of prevailing on their claim[s]. Plaintiffs have made this showing by submitting a verified complaint citing to the Georgia statute limiting the use of survey data and by prevailing on their temporary restraining order on the same issue before this Court.
It is not entirely clear what the court meant by this passage, and a review of the transcript *129of the hearing on the anti-SLAPP motion does not add clarity.
What is clear, however, is that the trial court did not properly apply the required step two analysis under OCGA § 9-11-11.1 with respect to the plaintiffs' claims. There was no discussion or analysis of whether the plaintiffs had "stated and substantiated a legally sufficient claim" for violations of the cited statutes.
**265Briggs , 81 Cal.Rptr.2d 471, 969 P.2d at 575. See Soukup , 39 Cal.4th 260, 46 Cal.Rptr.3d 638, 139 P.3d 30 at 51 (holding that the question is whether "the complaint is both legally sufficient and supported by a sufficient prima facie showing of facts to sustain a favorable judgment if the evidence submitted by the plaintiff is credited" (citation and punctuation omitted)). Moreover, neither the trial court nor the parties have addressed certain important preliminary questions.
The first such question is whether the statutes cited in the complaint apply here at all. For example, OCGA § 31-7-3.2 (j) appears in Article 1 of Chapter 7 of Title 31 of the Georgia Code, which establishes Georgia's regulatory framework for hospitals and related institutions, including nursing homes, which seems an unlikely place to find a statute regulating attorney advertising. See City of Guyton v. Barrow , 305 Ga. 799, 805, 828 S.E.2d 366, 2019 WL 2167460, Case Nos. S18G0944 & S18G0945 (decided May 20, 2019) ("The primary determinant of a text's meaning is its context, which includes the structure and history of the text and the broader context in which that text was enacted ...."). And the text of OCGA § 10-1-427 appears to contemplate enforcement, at least initially, by the Attorney General, not by private parties.
If the most natural reading of the statutory text is that the cited statutes do apply to the defendants' ads, there is a constitutional separation of powers issue that might require reading them not to apply, see State ex rel. Doyle v. Frederick J. Hanna & Assocs., P.C. , 287 Ga. 289, 290-294, 695 S.E.2d 612 (2010), or that might prevent them from applying, see Grecaa, Inc. v. Omni Title Svcs., Inc. , 277 Ga. 312, 312-313, 588 S.E.2d 709 (2003). There is also a significant First Amendment issue with respect to the application of each statute here, which the parties only tangentially addressed in the trial court and have not adequately addressed in their briefs on appeal.
In short, the trial court did not apply the proper standards at step two of the anti-SLAPP analysis, and the particular claims at issue in this case implicate complex and important questions of statutory interpretation and constitutional law. We should not address these claims in the first instance on appeal. Accordingly, we vacate the trial court's denial of the defendants' anti-SLAPP motion, and we remand the case to the trial court with direction to reconsider the motion under the analysis set out above. See, e.g., Gramiak v. Beasley , 304 Ga. 512, 522-523, 820 S.E.2d 50 (2018) ; Clayton County v. City of College Park , 301 Ga. 653, 656-657, 803 S.E.2d 63 (2017) ; Southern LNG, Inc. v. MacGinnitie , 294 Ga. 657, 667-669, 755 S.E.2d 683 (2014).
Judgment vacated, and case remanded with direction.
