In this lawsuit against the Department of Human Services,1 the trial court certified a class of plaintiffs. The Department appealed, and in Deal v. Miller, 321 Ga. App. 220 (739 SE2d 487) (2013), the Court of Appeals reversed, concluding that the named plaintiffs failed in several respects to show that class certification was warranted. We issued a writ of certiorari to review that decision, and we now affirm the judgment of the Court of Appeals.
1. The named plaintiffs in this lawsuit are indigent parents, all of whom say that they have been incarcerated for failures to pay child support following civil contempt proceedings initiated by the Department and in which the Department was represented by lawyers. The plaintiffs could not afford to hire their own lawyers for these proceedings. Without a lawyer to defend them, the plaintiffs contend, the proceedings in which they were incarcerated failed to comport with *505the constitutional guarantee of due process. Alleging that the Department routinely initiates such proceedings against indigent parents, but fails to provide lawyers for such parents at the expense of the Department, the plaintiffs sued, seeking declaratory and injunctive relief not only for themselves, but also for a class of all unrepresented and indigent parents who are threatened with incarceration in such proceedings. On the motion of the plaintiffs to certify this class, the trial court found that the plaintiffs had shown each of the four essential prerequisites for class certification under OCGA § 9-11-23 (a) , as well as the prerequisite for certification under OCGA § 9-11-23 (b) (2). Based on these findings, the trial court determined that a class action was warranted, and it certified the class.
The Court of Appeals reversed. To begin, the Court of Appeals correctly explained that the plaintiffs — if they were to be permitted to seek relief for the class that the trial court certified — had to prove that the class was sufficiently numerous,2 that the claims that they asserted on behalf of the class presented common questions,3 that their own claims are typical of those that they asserted on behalf of the class,4 that they are adequate representatives of the class,5 and that the declaratory and injunctive relief that they sought might be appropriately awarded to the class as a whole.6 See Deal, 321 Ga. App. at 221. In the end, the Court of Appeals concluded that the plaintiffs had failed to prove commonality and typicality, see id. at 222-226 (1) (a), and that they had failed as well to prove the propriety of relief for the class as a whole. See id. at 226-227 (1) (b). Though these conclusions may be right — we will get to that shortly — the reasoning by which the Court of Appeals reached them is not.
As we understand its opinion, the Court of Appeals premised all of its conclusions on a fundamental misunderstanding of the constitutional right to counsel. The Court of Appeals seems to have *506assumed that the named plaintiffs — and presumably, the other members of the class too — all have a constitutional right to appointed counsel in civil contempt proceedings of the sort about which the plaintiffs complain. See Deal, 321 Ga. App. at 224 (1) (a) (i) (acknowledging that “the named plaintiffs may have had the right to counsel” (emphasis omitted)). Even so, the Court of Appeals reasoned, if an indigent parent fails to assert his right to counsel in his own contempt proceeding • — • by timely requesting a lawyer, by securing a ruling on that request from the contempt court, and by appealing any finding of contempt entered without the benefit of counsel — the parent cannot be said to have been unconstitutionally denied counsel.7 See id. at 223-224 (1) (a) (i). Whether an indigent parent is advised of his right to request counsel is of no consequence, the Court of Appeals added, because no court has an obligation in civil contempt proceedings to inquire about counsel. See id. at 224 (1) (a) (i). Accordingly, the Court of Appeals explained, whether any class member had been denied a right to counsel would require an individualized inquiry about the extent to which they insisted upon counsel, and as a result, the plaintiffs could not show commonality among the class. See id. (“Here, whether the named plaintiffs actually were denied counsel is the essential question, because the answer determines whether they have shown the injury on which their theory of commonality depends.” (Emphasis in original.)). Because the named plaintiffs themselves had not insisted upon counsel in their own contempt proceedings, the Court of Appeals said, they could not show that their claims were typical of those asserted on behalf of the class. See id. at 226 (1) (a) (ii) (“Here, the named plaintiffs have not shown typicality in that they have not shown injury.”). And likewise, the Court of Appeals concluded, the plaintiffs could not show the propriety- of relief for the class as a whole, insofar as the record did not reflect “whether other putative class members have requested and been denied counsel.” Id. at 227 (1) (b).
Generally speaking, to the extent that the Constitution affords a right to counsel at government expense, it affords a right that is not *507waived merely by a party unknowingly failing to insist upon a lawyer in a proceeding in which he is not even advised that he might request counsel. That certainly is true of the categorical right to counsel that is guaranteed to the accused in criminal prosecutions by the Sixth Amendment. See, e.g., Brewer v. Williams, 430 U. S. 387, 404 (III) (97 SCt 1232, 51 LE2d 424) (1977) (“[T]he right to counsel does not depend upon a request by the defendant. . . .” (Citations omitted.)); Carnley v. Cochran, 369 U. S. 506, 513 (82 SCt 884, 8 LE2d 70) (1962) (“[I]t is settled that where the assistance of counsel is a constitutional requisite, the right to be furnished counsel does not depend on a request.” (Footnote omitted.)). It appears to be no less true of the more limited and conditional right to counsel that the courts have recognized in certain other proceedings as an incident of due process. See, e.g., Gagnon v. Scarpelli, 411 U. S. 778, 790 (III) (93 SCt 1756, 36 LE2d 656) (1973) (in probation or parole revocation proceedings, presupposing that the probationer or parolee will be “informed of his right to request counsel”); Vaughn v. Rutledge, 265 Ga. 773, 774 (2) (462 SE2d 132) (1995) (“A probationer is entitled... to be informed of his right to request counsel.” (Citation, punctuation and emphasis omitted.)). The Court of Appeals seems to have misconstrued our decision in Adkins v. Adkins, 242 Ga. 248, 248 (2) (248 SE2d 646) (1978), as suggesting that a trial court never is required to advise or to inquire about an entitlement to counsel in a civil contempt case. But in Adkins, we dealt with an assertion that the Sixth Amendment — which, of course, applies only in criminal proceedings and has no application whatsoever in a civil case — required a civil contempt court to inquire about counsel. We did not address in Adkins any right to counsel that arose from the guarantee of due process, as the plaintiffs in this case claim. Accordingly, to the extent that named plaintiffs or other class members have a constitutional right to appointed counsel, they do not waive that right simply by failing to insist upon counsel in proceedings in which no one advised them that they could ask for counsel.
2. We nevertheless conclude that the Court of Appeals was right when it determined that the plaintiffs failed to show the requisite commonality, typicality, and propriety of classwide relief. To show these things, the plaintiffs relied entirely on their assertion of a categorical constitutional right to appointed counsel. But in Turner v. Rogers, _ U. S. _ , _ (III) (B) (131 SCt 2507, 180 LE2d 452) (2011), the United States Supreme Court made perfectly clear that “the Due Process Clause does not automatically require the provision of counsel at civil contempt proceedings to an indigent individual who is subject to a child support order, even if that individual faces incarceration.” (Emphasis in original.) To be sure, Turner involved an *508assertion that indigent parents have a categorical right to appointed counsel in all civil contempt proceedings in which they are threatened with incarceration for a failure to pay child support. The plaintiffs in this case, on the other hand, assert only that indigent parents have a right to appointed counsel in civil contempt proceedings in which they are threatened with incarceration for a failure to pay child support and in which the Department is represented by a lawyer, a circumstance that the Supreme Court explicitly declined to address in Turner. See id. at_(III) (B) (“We do not address civil contempt proceedings where the underlying child support payment is owed to the State____[In such proceedings,] [t]he government is likely to have counsel or some other competent representative.” (Citations omitted.)). Still, the plaintiffs urge a categorical right, even if it is one more narrow than the categorical right rejected in Turner.
Although the plaintiffs cite a number of court decisions around the country to support their claim of a categorical constitutional right,8 most of these decisions were based on Lassiter v. Dept. of Social Svcs. of Durham County, 452 U. S. 18 (101 SCt 2153, 68 LE2d 640) (1981), and all were decided before Lassiter was clarified by Turner. In Lassiter, the Supreme Court recognized a “presumption that an indigent litigant has a right to appointed counsel only when, if he loses, he may be deprived of his physical liberty.” 452 U. S. at 26-27 (II) (A). As the Supreme Court later explained in Turner, however, Lassiter does not suggest categorical rights to appointed counsel in civil proceedings, even those that may lead to incarceration:
[T]he Court’s statements in Lassiter constitute part of its rationale for denying a right to counsel in that case. We believe those statements are best read as pointing out that the Court previously had found a right to counsel “only” in cases involving incarceration, not that a right to counsel exists in all such cases . . .
_U. S. at_(III) (A) (emphases in original).
Moreover, aside from “criminal prosecutions or proceedings functionally akin to a criminal trial,” the United States Supreme Court “has never found in the Due Process Clause a categorical right to *509appointed counsel.”9 Turner, _ U. S. at _ (Thomas, J., dissenting) (citation and punctuation omitted; emphasis supplied). See also Lassiter, 452 U. S. at 31 (II) (C) (no categorical right to appointed counsel in proceedings to terminate parental rights); Vitek v. Jones, 445 U. S. 480, 499 (100 SCt 1254, 63 LE2d 552) (1980) (Powell, J., concurring) (no categorical right to appointed counsel with respect to transfer of inmate to mental hospital); Middendorf v. Henry, 425 U. S. 25, 48 (III) (96 SCt 1281, 47 LE2d 556) (1976) (no categorical right to counsel in summary court-martial proceedings); Jeanne Charn, “Celebrating the ‘Null’ Finding: Evidence-Based Strategies For Improving Access to Legal Services,” 122 Yale L.J. 2206, 2217 (II) (A) (2013) (“The prospect of the Supreme Court recognizing a categorical right to counsel in civil cases is remote.”). Especially instructive, we think, is Gagnon, 411 U. S. at 787 (III), in which the Supreme Court found no categorical right to appointed counsel in probation and parole revocation proceedings generally, but it acknowledged that, “ [i] n some cases . . . the probationer’s or parolee’s version of a disputed issue can fairly be represented only by a trained advocate.” Id. at 788 (III). Like the narrow class of contempt proceedings about which the plaintiffs in this case complain, the Supreme Court then turned in Gagnon from revocations generally to a narrow class of revocation proceedings in which the need for appointed counsel might be more substantial:
[C]ases where, after being informed of his right to request counsel, the probationer or parolee makes such a request, based on a timely and colorable claim (i) that he has not committed the alleged violation of the conditions upon which he is at liberty; or (ii) that, even if the violation is a matter of public record or is uncontested, there are substantial reasons which justified or mitigated the violation and make revocation inappropriate, and that the reasons are complex or otherwise difficult to develop or present.
Id. at 790 (III). But even as to that particular class of revocation proceedings, the Supreme Court said that the circumstances ren*510dered the appointment of counsel only “fpjresumptively” necessary, not absolutely required. Id. (emphasis supplied).
We suppose that due process sometimes may require the appointment of counsel for an indigent parent in a civil contempt proceeding in which the parent is threatened with incarceration. And as in Gagnon, perhaps there is even a “presumptive” right to appointed counsel in some, such proceedings if the parent is opposed by government lawyers.10 But even so, presumptions sometimes can be overcome, and whether any particular parent is entitled to a lawyer at government expense depends always, we think, on the particular and unique circumstances of his case, including the complexity of the case, as well as the extent to which alternative measures might be employed to ensure that the proceeding is fundamentally fair. See State v. Currier, 295 P3d 837, 843-844 (Wyo. 2013). See also Gagnon, 411 U. S. at 790-791 (III). As the United States Supreme Court has reminded, “the requirements of due process are flexible and call for such procedural protections as the particular situation demands.” Wilkinson v. Austin, 545 U. S. 209, 224 (IV) (125 SCt 2384, 162 LE2d 174) (2005) (citation and punctuation omitted).
The dissent posits that, even if the United States Constitution affords no categorical right to appointed counsel in civil contempt proceedings of the sort about which the plaintiffs complain, maybe the Georgia Constitution affords such a right. This is not the case, however, in which to decide that question.11 Although the plaintiffs assert a categorical right under both the United States Constitution and the Georgia Constitution, they never have even attempted to make the case — in their pleadings, in their motions and briefs in the trial court on class certification, or in their appellate briefs — that the Georgia Constitution affords more procedural rights in civil contempt proceedings as a matter of due process than does the United States Constitution. To the extent they have mentioned the Georgia Constitution, they mention it only in passing, and almost always alongside a reference to the United States Constitution (or cases concern*511ing the United States Constitution). Nowhere in the papers filed by the plaintiffs do we find a reasoned argument — supported by an analysis of the pertinent constitutional text, structure, and history— that the guarantee of due process in the Georgia Constitution means something more in this context than the same guarantee in the United States Constitution. See Grady v. Unified Govt. of Athens-Clarke County, 289 Ga. 726, 731 (2) (b), n. 3 (715 SE2d 148) (2011). Nor do we find such an argument in the dissent, which simply muses that the Georgia Constitution might afford more process than the United States Constitution. We will not hang our decision on an argument that no one has made, and for the purposes of this appeal, we accept — as the parties seem to have accepted throughout this case — that the process due in this context under the United States Constitution and the Georgia Constitution is the same.
We do not decide in this case precisely when, if ever, a lawyer must be appointed for an indigent parent in a civil contempt proceeding about child support. We conclude only that there is no absolute, inflexible, and categorical right to appointed counsel in such proceedings as a matter of due process, even when the Department, represented by its own lawyers, pursues the incarceration of an indigent parent.12 That is enough to resolve this case. Because there is no categorical right, whether any named plaintiff or other member of the class even has a right to appointed counsel in any particular civil contempt proceeding depends upon highly individualized considerations. Accordingly, the plaintiffs cannot show commonality of the claims asserted on behalf of the class, see OCGA § 9-11-23 (a) (2), they cannot show that their own claims are typical of those of the class, see OCGA § 9-11-23 (a) (3), and they cannot show that classwide injunc*512tive and declaratory relief is in order. See OCGA § 9-11-23 (b) (2). For these reasons, the Court of Appeals was right to conclude that the trial court erred when it certified a class.
Judgment affirmed.
All the Justices concur, except Benham, J., who concurs in part and dissents in part.The lawsuit names Governor Nathan Deal and several Department officials as defendants, not the Department itself. But because the Governor and the other officials were sued only in their official capacities, the lawsuit amounts to a suit against the Department. For that reason, we refer in this opinion to the several defendants simply as the “Department.”
See OCGA § 9-11-23 (a) (1) (plaintiffs must show that “class is so numerous that joinder of all members is impracticable”).
See OCGA § 9-11-23 (a) (2) (plaintiffs must show that “[tjhere are questions of law or fact common to the class”).
See OCGA § 9-11-23 (a) (3) (plaintiffs must show that “[t]he claims ... of the representative parties are typical of the claims ... of the class”).
See OCGA § 9-11-23 (a) (4) (plaintiff must show that “[t]he representative parties will fairly and adequately protect the interests of the class”).
See OCGA § 9-11-23 (b) (2) (plaintiff must show that “[t]he party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making appropriate final injunctive relief or corresponding declaratory relief with respect to the class as a whole”). Although a plaintiff always must prove each of the four circumstances identified in OCGA § 9-11-23 (a) (l)-(4), a plaintiff need only prove one of the three circumstances identified in OCGA § 9-11-23 (b) (l)-(3). In this case, the trial court certified the class under OCGA § 9-11-23 (b) (2), and so, we do not consider OCGA § 9-11-23 (b) (1) or (b) (3).
The Court of Appeals put it this way:
In the present case, the named plaintiffs allege that they were injured because they were “unconstitutionally denied counsel.” However, ... it is undisputed that the plaintiffs did not request counsel at or prior to the civil contempt hearings that led to their incarceration. Nor did they appeal the trial courts’ findings of contempt, which means they never challenged their lack of appointed counsel below. Because the trial courts were not presented with requests to appoint counsel prior to the contempt hearings, and have never ruled on the later requests, plaintiffs have not been denied counsel in that context.

In In re Gault, 387 U. S. 1, 35-42 (87 SCt 1428, 18 LE2d 527) (1967), the Supreme Court held that the government must provide counsel for indigent juveniles in civil “juvenile delinquency” proceedings that could lead to incarceration as a matter of due process. But as both the majority and dissent in Turner noted, “[t]he civil juvenile delinquency proceeding at issue in Gault was little different from, and comparable in seriousness to, a criminal prosecution.” Turner, _ U. S. at _ (III) (A) (citation and punctuation omitted). See also id. at_ (Thomas, J., dissenting) (“Indeed, the only circumstance in which the Court has found that due process categorically requires appointed counsel is juvenile delinquency proceedings, which the Court has described as ‘functionally akin to a criminal trial.’ ” (Citation omitted)).
For this reason, trial courts should consider advising unrepresented parents in such proceedings that they may have a right to request counsel.
We suppose that the guarantee of due process in the Georgia Constitution might afford more procedural rights in civil contempt proceedings about child support than the same guarantee in the United States Constitution, if only because our Court has not addressed that question before. We note, however, that this Court has held in a number of other contexts that the process due under the United States Constitution and the Georgia Constitution is the same. See, e.g., DeKalb County School Dist. v. Ga. State Bd. of Ed., 294 Ga. 349, 369 (4) (a) (751 SE2d 827) (2013) (removal from public office); Joiner v. Glenn, 288 Ga. 208, 209 (702 SE2d 194) (2010) (termination of public employment); Britt v. Smith, 274 Ga. 611, 614 (556 SE2d 435) (2001) (guilty plea).
We recognize, of course, that class certification is not intended to he a mechanism for deciding the merits of a case. See Gay v. B.H. Transfer Co., 287 Ga. App. 610, 612 (652 SE2d 200) (2007). Nevertheless, the inquiry required to decide class certification sometimes may involve “some overlap with the merits of the plaintiff’s underlying claim. That cannot he helped. The class determination generally involves considerations that are enmeshed in the factual and legal issues comprising the plaintiff’s cause of action.” Wal-Mart Stores v. Dukes, _ U. S. _, _ (II) (A) (131 SCt 2541, 180 LE2d 374) (2011) (citation and punctuation omitted). See also McGarry v. Cingular Wireless, 267 Ga. App. 23, 25 (1) (599 SE2d 34) (2004). “Merits questions may he considered to the extent — but only to the extent — that they are relevant to determining whether the ... prerequisites for class certification are satisfied.” Amgen, Inc. v. Conn. Retirement Plans & Trust Funds, _ U. S. _, _ (II) (A) (133 SCt 1184, 185 LE2d 308) (2013) (citations omitted). Here, whether the named plaintiffs and the class have a categorical right to appointed counsel in the proceedings about which they complain is “both a merits question and a class question,” Carnett’s, Inc. v. Hammond, 279 Ga. 125, 129 (4) (610 SE2d 529) (2005), and it is one, therefore, that we properly may address on class certification. We note as well that the question is a purely legal one, and no discovery or resolution of factual issues is necessary to determine if the Constitution categorically requires counsel in these sorts of proceedings. See Phillips v. Asset Acceptance, 736 F3d 1076, 1081 (7th Cir. 2013).
