Grant, Justice.
The Georgia Department of Human Services, Division of Family and Children Services ("DFCS") appeals from the decision of the Lamar County Superior Court finding that Georgia's central child abuse registry is unconstitutional, both on its face and as applied to appellee Christopher Steiner. The trial court also found that DFCS failed to prove that Steiner committed an act of child abuse by a preponderance of the evidence as required to maintain Steiner's listing in the registry. This Court granted DFCS's application for discretionary review. We hold that Steiner failed to demonstrate a constitutionally protected liberty or property interest sufficient to trigger the due process protections that he claims were violated by operation of the registry, and because the Act was constitutionally applied to Steiner, he lacks standing to bring his facial challenge on that ground. We further hold that the child abuse registry is not criminal in nature, and that the superior court therefore erred in finding it to be so. And because an abuse investigator's determination about whether a report of child abuse is supported by the evidence is not a judicial function, the superior court erred in finding that the statute requiring the investigator to report such cases to DFCS for inclusion in the child abuse registry violates the separation of powers provision of the Georgia Constitution. Finally, because at least "some evidence" supported the administrative hearing officer's conclusion that DFCS had proved an act of child abuse as defined for purposes of the child abuse registry, the superior court erred in reversing the administrative law court. We reverse.
I.
Georgia's central child abuse registry, also known as the Child Protective Services Information System ("the Act"), is a statutory system that provides for the establishment *888and maintenance of a central registry containing information about "substantiated" cases of child abuse. See OCGA §§ 49-5-18 - 49-5-187. The Act requires that DFCS investigate reports of child abuse and, if the abuse investigator finds by a preponderance of the evidence that an act of child abuse occurred, information must be added to the registry about the abuse, the abuser, the child victim, and the child's guardian. See OCGA §§ 49-5-182, 49-5-183. Access to the registry is limited to certain government child abuse investigators and government or licensed childcare-related entities. The registry may only be used for the following purposes: conducting child abuse investigations; screening applicants for childcare-related employment, licensing, or volunteer activities; conducting background checks on current or prospective foster parents and adoptive parents; compiling statistical information regarding substantiated cases of abuse; responding to inquiries from individuals seeking to find out whether the individual's own name is included in the registry; and meeting federal funding requirements. See OCGA § 49-5-185.
OCGA § 49-5-183 requires that DFCS must notify an alleged abuser when his or her name is added to the registry. See OCGA § 49-5-183 (a). The alleged abuser may then request an evidentiary hearing before an administrative law judge ("ALJ") by submitting a written request for a hearing to DFCS within ten days after receiving the notice. See OCGA § 49-5-183 (a) & (c). The general public is excluded from the administrative hearing, and the associated records are kept under seal. See OCGA § 49-5-183 (e). The ALJ makes the final "administrative determination regarding whether, based on a preponderance of evidence, there was child abuse committed by the alleged child abuser to justify the investigator's determination of a substantiated case." OCGA § 49-5-183 (d). If not, the ALJ must order the alleged abuser's name removed from the registry. OCGA § 49-5-183 (e). Either party may seek judicial review of the ALJ's decision by filing a petition in the superior court of the county in which the administrative hearing was held. OCGA § 49-5-183 (f). The records and judicial review proceedings in the superior court also are closed to the public. Id.
In late October 2016, K.S., a 13-year-old girl, was reported missing by her grandmother, who is her legal guardian. K.S.'s grandmother told members of the local Sheriff's Office that K.S. was likely at Steiner's home, and the investigation evolved into an interference-with-custody case. K.S. was later found to have been at Steiner's home as her grandmother had suspected.1
During the course of the investigation, a forensic interview was conducted with K.S. Immediately after the interview, a deputy sheriff spoke with K.S. and obtained a written statement from her that included the following description of an encounter with Steiner several days earlier at K.S.'s grandmother's home:
I usually show my affection hugging him. I leaned against him on his stomach and he wrapped his arms around
me. He started to hump me a way a dog would. I said stop the first time. Then he done it again. When he done it the 2nd time my nana turned around and saw it. I got off of him and walked away a little from him to make him stop.
According to K.S.'s statement, Steiner was 52 years old at the time. DFCS conducted an investigation and determined that this encounter was a "substantiated case" of child sexual abuse, as defined in OCGA § 49-5-180 (8) & (10) and OCGA § 19-7-5 (b) (10).2
*889Steiner's name and identifying information were therefore added to the child abuse registry, along with a copy of the DFCS investigator's report and a classification of the abuse as sexual.
In January 2017, after Steiner was added to the registry, DFCS mailed him a letter notifying him of the determination that he had committed a substantiated case of child abuse, of his listing in the child abuse registry, and of the procedure for contesting that listing. The letter identified the "maltreatment" as fondling and the "maltreatment type" as sexual abuse. It informed Steiner that the date of the alleged abuse was October 29, 2016, and that the abuse occurred in Lamar County. On the last page of the notice, the allegations of child abuse were summarized as follows:
You were substantiated on as a result of K.S. maltreator exposed the child to inappropriate sexual contact which resulted in the maltreator inappropriately touched and dry humped her in the residence of the legal guardian.
Steiner requested a hearing before an ALJ, contesting his listing in the registry and contending that the Act was unconstitutional on its face and as applied to him. Specifically, Steiner argued that it was impossible to tell from the vague and ungrammatical notice what he was accused of doing, who K.S. was, what was meant by "dry humped," and whether K.S. had been "exposed" to sexual contact by witnessing sexual contact between others or by being sexually touched by Steiner or someone else. He also argued that the conduct described in the notice was not an act of child abuse.
Steiner contended that the Act violated the Fifth and Fourteenth Amendments to the United States Constitution and parallel provisions of the Georgia Constitution because it did not provide for adequate notice and a pre-deprivation hearing. He further argued that the Act violated the separation of powers doctrine in that it vested a DFCS investigator with the judicial power to determine whether the allegations of child abuse were substantiated by a preponderance of the evidence. Finally, he contended that because the Act was criminal in nature, he should be granted "the full panoply of rights of a criminal defendant" under the state and federal constitutions, including the Sixth Amendment right to a speedy and public trial.
Following a hearing at which K.S. and two other witnesses testified, the ALJ issued a written decision rejecting Steiner's petition for removal from the registry and noting that Steiner's motion to declare the Act unconstitutional had been denied at the hearing.3 The ALJ stated that he had questioned K.S. before she testified and determined that she was capable of giving reliable testimony. The ALJ found that K.S. had recognized the written statement that she gave to the sheriff's deputy and testified that she was telling the truth when she wrote the statement. She also testified that Steiner "tried to hump her like a dog" and that her Nana saw it the second time, which is what she wrote in the statement.4 The ALJ concluded that the evidence showed that Steiner had "dry humped" K.S., a 14-year-old5 minor child, twice; that K.S. told him to stop after he did it the first time; and that "[t]here [was] no evidence this was consensual." Applying the preponderance of the evidence standard, the ALJ determined that DFCS had substantiated a case of child sexual abuse, as defined in OCGA § 19-7-5 (b) (10) (G), against Steiner. The ALJ therefore affirmed DFCS's decision to include the incident in the registry.
Steiner appealed the administrative decision to the Superior Court of Lamar County, *890Georgia. He contested the legal basis for his inclusion in the registry, incorporating the constitutional claims from his petition in the Office of State Administrative Hearings and arguing that the ALJ's decision was clearly erroneous and arbitrary and capricious because the term "dry humping" was never defined or shown to meet the definition of child abuse. Steiner did not appear to contend that he did not actually know who K.S. was, or that he did not have any contact with her.
After hearing oral argument from the parties, the superior court found that (1) the Act violated Steiner's due process rights under the Fourteenth Amendment of the United States Constitution6 by providing insufficient notice of the act of which Steiner was accused, because the allegation in the notice was too vague and unclear to permit Steiner to prepare a defense; (2) the Act is punitive in application and, because it fails to provide the full range of protections required in a criminal proceeding, it is unconstitutional under the Fifth, Sixth, and Fourteenth Amendments of the United States Constitution; (3) the Act violates the separation of powers principle under the Georgia Constitution, Ga. Const. of 1983, Art. I, Sec. II, Par. III, in that "executive branch officials have been vested with the right to perform a judicial function"; and (4) DFCS failed to prove an act of child abuse by a preponderance of the evidence. Consistent with its conclusions, the superior court reversed the ALJ's findings and ordered Steiner's name to be stricken from the child abuse registry. DFCS filed a timely application for discretionary review, which we granted.
II.
We presume that statutes are constitutional, and "before an Act of the legislature can be declared unconstitutional, the conflict between it and the fundamental law must be clear and palpable and this Court must be clearly satisfied of its unconstitutionality." JIG Real Estate, LLC v. Countrywide Home Loans, Inc. , 289 Ga. 488, 490, 712 S.E.2d 820 (2011) (citation and punctuation omitted). Because all presumptions are in favor of the constitutionality of a statute, the burden is on the party claiming that the law is unconstitutional to prove it. Id.
With these principles in mind, we turn to the superior court's conclusion that Steiner's Fourteenth Amendment right to procedural due process was violated because the notice he received of his inclusion in the registry was inadequate to inform him of what he was accused of doing. The Fourteenth Amendment prohibits government deprivation of "life, liberty, or property, without due process of law." U.S. Const. amend. XIV, § 1. In evaluating a procedural due process challenge in a non-criminal proceeding,7 we engage in a two-step analysis: first, we must determine whether a constitutionally protectable liberty or property interest exists; if so, we determine the nature and extent of the procedural protections required. See Gregory v. Sexual Offender Registration Review Bd. , 298 Ga. 675, 685-687, 784 S.E.2d 392 (2016). In determining what process is due, we employ the three-factor balancing test set out in Mathews v. Eldridge , 424 U.S. 319, 335, 96 S.Ct. 893, 47 L.Ed.2d 18 (1976) to weigh the competing interests involved. See, e.g., Gregory , 298 Ga. at 686-687, 784 S.E.2d 392. Those factors include the private interest affected by the state action; the risk of an erroneous deprivation of the interest under the existing scheme along with the probable value, if any, of additional or substitute procedural safeguards; and finally, the interest of the government. Mathews , 424 U.S. at 335, 96 S.Ct. 893.
The superior court applied the Mathews balancing test, finding that "[f]undamental rights are at stake" for anyone included in *891the registry and that Steiner's "liberty interests are significant and compelling." Accordingly, the court concluded that due process required the State to provide notice to Steiner before-not after-adding his name to the registry. The court further found that because the notice that Steiner received was essentially incomprehensible8 and was not sent until after Steiner was added to the registry, his due process rights were violated and the Act was unconstitutional as applied to him.
But "the range of interests protected by procedural due process is not infinite." Bd. of Regents of State Colls. v. Roth , 408 U.S. 564, 570, 92 S.Ct. 2701, 33 L.Ed.2d 548 (1972). And "[t]o determine whether due process requirements apply in the first place, we must look not to the 'weight' but to the nature of the interest at stake." Gregory , 298 Ga. at 685, 784 S.E.2d 392 (quoting Greenholtz v. Inmates of Neb. Penal & Corr. Complex , 442 U.S. 1, 7, 99 S.Ct. 2100, 60 L.Ed.2d 668 (1979) ) (emphasis in original). As Steiner concedes, injury to reputation alone does not implicate "any 'liberty' protected by the procedural guarantees of the Fourteenth Amendment." Paul v. Davis , 424 U.S. 693, 708-709, 96 S.Ct. 1155, 47 L.Ed.2d 405 (1976). We followed this directive from the U.S. Supreme Court in State v. Jackson , 269 Ga. 308, 496 S.E.2d 912 (1998), a challenge to the previous child abuse registry where we confirmed that "stigmatization of reputation alone does not implicate a liberty interest sufficient to invoke federal due process protection." 269 Ga. at 310, 496 S.E.2d 912.
So Steiner must show that-in addition to the obvious stigma associated with being labeled a child abuser-his inclusion in the registry also "distinctly altered or extinguished" a "right or status previously recognized by state law." Paul , 424 U.S. at 710-712, 96 S.Ct. 1155. This requirement for establishing a liberty interest sufficient to invoke the due process protections of the Fourteenth Amendment is known as the "stigma-plus" test. See, e.g., Behrens v. Regier , 422 F.3d 1255, 1259 (11th Cir. 2005) ("Under [the stigma-plus] test, 'a plaintiff claiming a deprivation based on defamation by the government must establish the fact of the defamation "plus" the violation of some more tangible interest before the plaintiff is entitled to invoke the procedural protections of the Due Process Clause.' ") (citation omitted).
Accordingly, if DFCS "has only defamed [Steiner]-without depriving him of any right or status recognized under state law-then his injury does not rise to the level of a constitutional deprivation and his procedural due process claim must fail." Id. at 1261. But Steiner's only allegation related to the deprivation of a liberty interest was that the registry listing impairs his ability to work as a childcare provider or teacher.9 This bare assertion is not enough.
It may be true that entities with access to the registry would decline to license or employ *892Steiner as a childcare provider or teacher; indeed, use as a screening tool before granting a childcare-related license or employment is a key function of the registry. But Steiner made no claim that he has ever worked or applied to work in the childcare field before, or even that he has any intention of doing so in the future. Without an allegation that he has ever attempted to do the activities that he claims are now barred to him-or even that he had any intention of doing them before he was included in the registry-Steiner has not demonstrated that his listing has set any non-reputational obstacle in his path. We do not agree that the theoretical possibility that Steiner will, in the future, develop an interest in working in child care rises to the level of a "right or status" granted by the state.10
Our decision on this issue is consistent with opinions from other jurisdictions holding that the impact of a child abuse registry listing on future job prospects is insufficient to provide a constitutionally-protected liberty or property interest.11 See Smith v. Siegelman , 322 F.3d 1290, 1296-1298 (11th Cir. 2003) (although inclusion in Alabama's child abuse registry could adversely affect future employment rights, registrant could not show a protected liberty interest where he had not been "discharged, demoted, or rejected from a job" or even "passed over for promotion"); Duran v. Buckner , 157 So.3d 956, 970-971 (Ala. Civ. App. 2014) (citing Smith and holding that general allegations of harm to future job prospects were insufficient); Watso v.Colorado Dep't of Social Servs. , 841 P.2d 299, 304-305 (Colo. 1992) (possibility that appellants might be screened by future employers should they seek childcare-related employment insufficient to form protected property interest); New Jersey Div. of Youth & Family Servs. v. M.R. , 314 N.J.Super. 390, 715 A.2d 308, 314-315 (N.J. Super. Ct. App. Div. 1998) (theoretical impact on ability to be a childcare provider insufficient to satisfy the "plus" element of stigma-plus test).
Our holding is also consistent with those decisions finding that a liberty or property interest did exist where the appellants were already employed as childcare providers, or had at least made some showing that child care was their chosen occupation. See Humphries v. Cty. of Los Angeles , 554 F.3d 1170, 1182-1183 (9th Cir. 2009) (registry listing interfered with teacher's future credentialing and enrollment in certain college courses), reversed on other grounds by Los Angeles Cty. v. Humphries , 562 U.S. 29, 131 S.Ct. 447, 178 L.Ed.2d 460 (2010) ; Dupuy v. Samuels, 397 F.3d 493, 503-504 (7th Cir. 2005) (childcare workers effectively barred from future employment in their chosen field by their listing in the registry); Valmonte v. Bane , 18 F.3d 992, 1000 (2d Cir. 1994) (appellant had worked as a school paraprofessional and intended to apply for childcare positions); Jamison v. Mo. Dep't of Soc. Servs., Div. of Family Servs. , 218 S.W.3d 399, 402 (Mo. 2007) (nurses who operated or were employed by residential childcare center had implicated liberty interests where mandatory registry screening impacted employment and licensing). With those few courts that have found that potential restriction of future employment prospects alone is sufficient to meet the "plus" element of Paul 's "stigma-plus" test, we simply disagree. See Winston v. State Dep't of Social and Rehab. Svcs. , 274 Kan. 396, 49 P.3d 1274, 1284 (2002) (finding a protected liberty interest where registry listing prohibits employment, volunteering, or operation of childcare facility); In re W.B.M. , 202 N.C.App. 606, 690 S.E.2d 41, 49 (2010) (impact on employability or fitness to care for or adopt children constitutes deprivation of liberty interests under North Carolina Constitution).
*893Steiner also argues that his registry listing may be used against him in a future criminal proceeding. This contention is likewise speculative. Steiner concedes that no criminal charges have been brought related to the incident forming the basis for his registry listing. If criminal charges were brought at some future date, Steiner would be entitled to the full range of constitutional and statutory protections applicable to that separate criminal proceeding. Although the Act provides for the use of information in the registry by prosecutors "in any court proceeding in the course of any criminal prosecution," such use is limited to circumstances in which the information "is otherwise admissible." OCGA § 49-5-186 (b) (1). This provision does not change the operation of the rules of evidence or otherwise "alter or extinguish" any of the constitutional or statutory rights afforded to defendants in criminal proceedings. The unsupported possibility of a future criminal proceeding in which information from Steiner's registry listing is used against him is too remote and speculative to amount to the alteration or extinguishment of a state-given right for purposes of the Paul stigma-plus test.
Because Steiner did not allege or show that inclusion in the registry deprives him of any constitutionally protected liberty or property interest, the procedural guarantees of the Fourteenth Amendment are not implicated. Steiner's as-applied challenge to the Act fails.
III.
Steiner also raised, and the superior court sustained, several facial constitutional challenges to the Act, which we will consider in turn. To begin, because Steiner's as-applied due process challenge to the Act fails, his facial challenge on that same ground cannot succeed.
"A facial challenge to a legislative Act is, of course, the most difficult challenge to mount successfully, since the challenger must establish that no set of circumstances exists under which the Act would be valid." United States v. Salerno , 481 U.S. 739, 745, 107 S.Ct. 2095, 95 L.Ed.2d 697 (1987) ; see Bello v. State , 300 Ga. 682, 685-686, 797 S.E.2d 882 (2017). And as we have explained, except in the context of certain First Amendment challenges, "one whose own conduct may constitutionally be proscribed cannot challenge a law on the ground that it might conceivably be applied unconstitutionally to others." Hourin v. State , 301 Ga. 835, 837, 804 S.E.2d 388 (2017) ; see Catoosa Cty. v. R.N. Talley Props., LLC , 282 Ga. 373, 375, 651 S.E.2d 7 (2007). The United States Supreme Court has offered a similar holding in the context of Article III standing: "[A] party has standing to challenge the constitutionality of a statute only insofar as it has an adverse impact on his own rights. As a general rule, if there is no constitutional defect in the application of the statute to a litigant, he does not have standing to argue that it would be unconstitutional if applied to third parties in hypothetical situations." Ulster Cty. v. Allen , 442 U.S. 140, 154-155, 99 S.Ct. 2213, 60 L.Ed.2d 777 (1979). In short, because Steiner has not shown that the Act is unconstitutional as applied to him on due process grounds, his facial challenge also fails.12
IV.
Steiner next asserted that the Act functions as a criminal rather than a civil statute. The superior court agreed, finding that because the Act is punitive in nature, those included in the registry are "entitled to the full panoply of rights of a criminal defendant" under the Fifth, Sixth, and Fourteenth Amendments to the United States Constitution, including the Fifth Amendment protection against self-incrimination and the Sixth Amendment rights to counsel and to a "speedy and public trial." U.S. Const. amends. V, VI, XIV ; see United States v. Ward , 448 U.S. 242, 248, 100 S.Ct. 2636, 65 L.Ed.2d 742 (1980) (noting that the protections *894of the Sixth Amendment and the Self-Incrimination Clause of the Fifth Amendment are expressly limited to criminal cases). That conclusion is incorrect.
In determining that the Act is "quasi-criminal" in nature, the superior court relied in part on our decision in Jackson , 269 Ga. at 310, 496 S.E.2d 912. But Jackson is a thin reed for that conclusion. In Jackson we did not hold that the child abuse registry was criminal in nature, or that the full range of rights afforded to criminal defendants must be granted to those contesting inclusion in the registry. Rather, we held that because Jackson had met the "stigma plus" standard, due process required that he be "afforded the same protections in regard to the rights to compel and confront witnesses as are afforded to constitutionally protected interests in criminal prosecutions." Id. (emphasis supplied). We concluded on that basis that the prior version of the child abuse registry was unconstitutional because it prohibited an alleged abuser from calling a child victim under the age of 14 as a witness at any hearing provided under the Act. See id. at 311-312, 496 S.E.2d 912. That provision has since been repealed, and there is no similar provision in the current version of the Act. Moreover, that decision was plainly based on this Court's due process analysis, and not a conclusion that the Act is criminal in nature.
Although we did not consider in Jackson whether the Act was criminal in nature, we do so now, and readily conclude that it is not. In assessing whether a statutory scheme is criminal or civil, the first step is to "consider the statute's text and its structure to determine the legislative objective." Smith v. Doe , 538 U.S. 84, 92, 123 S.Ct. 1140, 155 L.Ed.2d 164 (2003). Where the legislature has exhibited an intention to enact a civil regulatory scheme, we next evaluate "whether the statutory scheme [is] so punitive either in purpose or effect as to negate that intention." United States v. Ward , 448 U.S. 242, 248-249, 100 S.Ct. 2636, 65 L.Ed.2d 742 (1980) ; see Cisco v. State , 285 Ga. 656, 658-659, 680 S.E.2d 831 (2009). Only "the clearest proof" of punitive purpose or effect will serve to negate the legislature's evident intention with regard to the nature of the statute. Kansas v. Hendricks , 521 U.S. 346, 361, 117 S.Ct. 2072, 138 L.Ed.2d 501 (1997) (citation and punctuation omitted).
Here, the General Assembly placed the statutes establishing the child abuse registry in Title 49, Chapter 5 of the Georgia Code, pertaining to "Social Services" and "Programs and Protection for Children and Youth." The registry is to be "operated in such a manner as to enable abuse investigators to: (1) Immediately identify and locate substantiated cases; and (2) Maintain and produce aggregate statistical data of substantiated cases." OCGA § 49-5-181 (b). Both the placement of the Act in the Code and its stated function evidence the statute's civil objectives-to act as a resource for abuse investigators and childcare agencies, not to punish alleged child abusers. See Smith , 538 U.S. at 93-94, 123 S.Ct. 1140 ("[W]here a legislative restriction is an incident of the State's power to protect the health and safety of its citizens, it will be considered as evidencing an intent to exercise that regulatory power, and not a purpose to add to the punishment.") (citation and punctuation omitted).
We next examine whether any negative effects of the Act are objectively "so punitive in form and effect as to render them criminal despite [the legislature's] intent to the contrary." Hudson v. United States , 522 U.S. 93, 104, 118 S.Ct. 488, 139 L.Ed.2d 450 (1997) ; see Cisco , 285 Ga. at 658-659, 680 S.E.2d 831. This analysis is guided by consideration of the factors identified in Kennedy v. Mendoza-Martinez , 372 U.S. 144, 83 S.Ct. 554, 9 L.Ed.2d 644 (1963). See Hudson , 522 U.S. at 104, 118 S.Ct. 488 ; Cisco , 285 Ga. at 658-659, 680 S.E.2d 831. The seven Mendoza-Martinez factors "are neither exhaustive nor dispositive, but are useful guideposts." Smith , 538 U.S. at 97, 123 S.Ct. 1140 (citations and punctuation omitted).
In Smith , the United States Supreme Court identified five of the seven Mendoza-Martinez factors as most relevant to the analysis of whether a statutory scheme establishing a sex-offender registry was punitive rather than civil in application, and we follow that Court's example in focusing our *895analysis here. Those five factors include whether the Act "has been regarded in our history and traditions as a punishment; imposes an affirmative disability or restraint; promotes the traditional aims of punishment; has a rational connection to a nonpunitive purpose; or is excessive with respect to this purpose." Smith , 538 U.S. at 97, 123 S.Ct. 1140 ; see Mendoza-Martinez , 372 U.S. at 168-169, 83 S.Ct. 554.13 An analysis of these factors leads to the conclusion that the Act is civil, not punitive, in both purpose and effect. First , maintaining information about a "substantiated case" of child abuse and permitting limited access to that information for specified reasons does not fit within the historic category of punishment. The Act's limited access and confidentiality provisions strongly support the conclusion that its purpose is to make information available to those who need it for child protective functions, rather than to punish the alleged abusers by "shaming" them; in fact, the list would be quite ineffective as a shaming tool given its firm confidentiality limitations. In Smith , by way of comparison, the United States Supreme Court concluded that even publicizing information about a sex offender's criminal record was not akin to historic "shaming" punishments. Smith , 538 U.S. at 98-99, 123 S.Ct. 1140.
Second , and perhaps most telling here, the Act does not impose any "affirmative disability or restraint" on those included in the child abuse registry. As we have already described, Steiner himself has offered no evidence that his inclusion on the list has impacted his life in any way at all. And again, the registry at issue is more narrow than the sex offender registry-which we have also found to be a civil regulatory scheme that is not punitive in nature, see Rainer v. State , 286 Ga. 675, 675-676, 690 S.E.2d 827 (2010).
The superior court was incorrect when it found that the registry is punitive in effect because it precludes those identified as child abusers from working or becoming licensed in the childcare field. As an initial matter, this is not true according to the terms of the statute; the list is accessible to certain agencies, but the Act does not contain any specific prohibition on hiring or licensure. But even if the Act did explicitly prohibit agencies with access to the registry from hiring or licensing individuals included in the registry as child abusers, the foreclosure of some employment opportunities would not render the Act criminal in nature. See Hudson , 522 U.S. at 104, 118 S.Ct. 488 ("While petitioners have been prohibited from further participating in the banking industry, this is 'certainly nothing approaching the "infamous punishment" of imprisonment.' " (quoting Flemming v. Nestor , 363 U.S. 603, 617, 80 S.Ct. 1367, 4 L.Ed.2d 1435 (1960) ) ).
Third , the Act does not "promote the traditional aims of punishment-retribution and deterrence." Mendoza-Martinez , 372 U.S. at 168, 83 S.Ct. 554. The superior court found that a listing in the registry serves as a deterrent, because an individual included in the registry is "deterred" from working with children. Well, yes. But working with children is not the sort of illegal conduct that the word "deterrence" typically references in this context. And to the extent that an impediment to working in the childcare field may also prevent future acts of child abuse, this indirect deterrent effect does not render the Act punitive. See, e.g., Smith at 102, 123 S.Ct. 1140 ("Any number of governmental programs might deter crime without imposing punishment."). In any event, the statutory provisions limiting access to the registry-indeed, unauthorized access is itself a crime, see OCGA § 49-5-186 (c) & (d) -demonstrate that the list cannot be fairly characterized as a warning to others to avoid acts of abuse. As for the other traditional aim of punishment, retribution, the superior court did not identify anything retributive in the Act. Nor do we.
Fourth , the Act has a legitimate nonpunitive function-to protect children by providing information about reports of child abuse to childcare-related government agencies and licensed childcare providers. Fifth , and finally, *896including an alleged abuser in a limited-access registry is not excessive in relation to this function. The fact that information about an act of alleged abuse remains in the registry unless removed through the administrative and judicial review provisions of the Act does not render the Act's provisions excessive in relation to its purpose of notifying childcare providers and agencies of incidents of abuse; presumably some would argue that keeping cases on the list is necessary to that purpose. In sum, the superior court's conclusion that the Act is criminal cannot be supported.
V.
The superior court also summarily found that the Act violates the separation of powers doctrine because "at the agency level, executive branch officials have been vested with the right to perform a judicial function." This appears to refer to Steiner's argument that a child abuse investigator is performing a judicial function when he or she determines that a report of child abuse is a "substantiated case"-that is, that the report "has been confirmed based upon a preponderance of the evidence." OCGA § 49-5-180 (10). The abuse investigator is required to notify DFCS of any substantiated case of abuse, and DFCS is then required to include information about the report and the alleged abuser in the registry. But the fact that the statute uses a legal term of art to define "substantiated case" does not convert the role of an investigator from an administrative one to a judicial one.
The Georgia Constitution provides specific roles for the three branches of state government. See generally
Ga. Const. of 1983, Art. III, Art. V., Art. VI. "The legislative branch enacts the law, the judiciary interprets those laws and the executive branch enforces those laws until they are amended or held to be unconstitutional." Harbuck v. State , 280 Ga. 775, 778, 631 S.E.2d 351 (2006) (citation omitted). The Georgia Constitution is also clear that one branch cannot subsume another's territory: "The legislative, judicial, and executive powers shall forever remain separate and distinct; and no person discharging the duties of one shall at the same time exercise the functions of either of the others except as herein provided." Ga. Const. of 1983, Art. I, Sec. II, Par. III. Put plainly, one person cannot perform both executive and judicial functions. See Brown v. Scott , 266 Ga. 44, 46, 464 S.E.2d 607 (1995).
Still, as noted in the only case Steiner cited to support his argument, the separation of powers mandated by our constitution "is not and from the nature of things can not be total." Perdue v. Baker , 277 Ga. 1, 13, 586 S.E.2d 606 (2003) (citation and punctuation omitted). "The separation of powers principle is sufficiently flexible to permit practical arrangements in a complex government." Id. (citation and punctuation omitted). This Court has recognized that administrative agencies may make quasi-judicial decisions in the course of implementing statutory law. See Dep't of Transp. v. Del-Cook Timber Co., Inc. , 248 Ga. 734, 739, 285 S.E.2d 913 (1982) ("[F]requently, within the exercise of their power, [agencies] are called upon to make factual determinations and thus adjudicate, and it is in that sense that they are also recurrently considered to be acting in a quasi-judicial capacity.") (citations omitted); see also State of Ga. v. Int'l Keystone Knights of the Ku Klux Klan, Inc. , 299 Ga. 392, 401-402, 788 S.E.2d 455 (2016). We have also recognized that " '[t]his dual role which administrative agencies play has long been accepted in this State as being constitutionally permissible. (Cits.) However, this authority is not the same and, therefore, is distinguishable from the exercising of the "judicial powers" of this State.' " Bentley v. Chastain , 242 Ga. 348, 350, 249 S.E.2d 38 (1978) (quoting Dep't of Nat. Res. v. Linchester Sand & Gravel Corp. , 274 Md. 211, 334 A.2d 514, 522 (1975) ).
With this background, we consider Steiner's claim that the Act violates the separation of powers. DFCS is an arm of the executive branch whose primary purpose is "to protect children." OCGA § 49-3-6 ; see OCGA § 49-5-8. Among other tasks, DFCS is charged with receiving and investigating reports of child abuse. See OCGA §§ 19-7-5 ; 49-5-8 (a) (2) (B). The judicial branch, on the other hand, must " 'adjudicate any and all *897justiciable questions presented to it in litigation.' " Wolcott v. State , 278 Ga. 664, 666, 604 S.E.2d 478 (2004) (citation omitted). With respect to the child abuse registry, the abuse investigator's role is limited to investigating reports of child abuse and notifying DFCS if the investigator finds sufficient evidence to conclude that the abuse more likely than not occurred. See OCGA § 49-5-182. This is well within the scope of duties of an executive branch employee. See, e.g., Harbuck , 280 Ga. at 778, 631 S.E.2d 351 (police officer making probable cause determination is not performing legislative function); Mann v. State , 278 Ga. 442, 444, 603 S.E.2d 283 (2004) (probation officers' authority to arrest probationers for suspected violations of the sex offender residency statute does not grant judicial authority to probation officers). The administrative action of the investigation does not approach the boundary line separating executive action from judicial.
Steiner's argument focuses on the investigator's role in determining whether an alleged abuser's name is added to the child abuse registry. But the fact that the Act mandates that all substantiated cases of abuse be included on a list of substantiated cases does not transform the investigator's quintessentially executive function of investigating allegations of abuse into a judicial one-surely DFCS investigators are permitted to reach some kind of conclusion about whether abuse has occurred in a particular situation.
The investigator is not charged with hearing argument and testimony or deciding a dispute between parties; nor is the investigator expected to review his or her own decision regarding whether the evidence substantiates the allegation of abuse. Cf. Humphries , 554 F.3d at 1197 (child abuse investigator may not both determine whether abuse allegations warrant placement in the child abuse registry and hear appeals from his own decision without violating due process fairness principles). Instead, the alleged abuser has the right to request a hearing before an ALJ, who makes the final agency decision after hearing evidence and argument from the alleged abuser and from DFCS. OCGA § 49-5-183 (d). The role of the abuse investigator in the determination of whether an incident should be in the child abuse registry does not violate the constitutional principle of separation of powers.
VI.
The ALJ determined that DFCS had shown by a preponderance of the evidence that Steiner committed an act of child abuse, as defined in OCGA § 19-7-5 (b) (10). Specifically, the ALJ found that Steiner "dry humped" K.S., a 14-year-old child, two times; after the first time, K.S. told Steiner to stop, but he did it again. After the second time, K.S. "got off of" Steiner and walked away from him to make him stop. The ALJ noted that, during her testimony at the administrative hearing, K.S. gave some further description of what Steiner had done when she testified that he "tried to hump her like a dog."
The superior court reversed the ALJ's decision, finding that DFCS had not proved an act of child abuse by a preponderance of the evidence because the child was not asked to define the term "dry humped," and it was not clear to the court whether Steiner's conduct involved any physical contact with the child. But by questioning the meaning of the child's testimony, the superior court improperly intruded upon the ALJ's role as the finder of fact and substituted its judgment for that of the ALJ regarding the import of witness testimony and the credibility of a witness. On issues involving findings of fact, "the ALJ's decision must be affirmed where there is 'any evidence' to support it." Hughey v. Gwinnett Cty. , 278 Ga. 740, 742, 609 S.E.2d 324 (2004) (citation omitted); see Georgia Real Estate Comm'n v. Burnette , 243 Ga. 516, 516, 255 S.E.2d 38 (1979) (superior court "erred in substituting its judgment for that of the agency as to the weight of the evidence").
The term "hump like a dog" is within common understanding, and it is reasonable to conclude that the ALJ understood this descriptive phrase to mean that Steiner performed "an act of apparent sexual stimulation." OCGA § 19-7-5 (b) (10) (G). Further, the evidence that the child was "lean[ing] against [Steiner] on his stomach" and Steiner *898"wrapped his arms around" her before "hump[ing]" her the "way a dog would" supported the ALJ's implicit finding that the act involved physical contact, as did K.S.'s statement that she had to "g[e]t off of" Steiner and walk away from him to make him stop. Accordingly, at least some evidence exists to support the ALJ's finding that there was "[p]hysical contact in an act of apparent sexual stimulation or gratification with [Steiner's] clothed or unclothed genitals." OCGA § 19-7-5 (b) (10) (G).
The superior court also noted its concern with the statement in the ALJ's order that there was no evidence that the act was consensual, which indicated to the court that the ALJ may have shifted to Steiner the burden of proving that K.S. consented to the act. This concern was misplaced. The ALJ specifically addressed the burden of proof at the hearing, where the ALJ stated (and DFCS acknowledged) that DFCS had the burden of proving by a preponderance of the evidence that an act of child abuse as defined in the Act had occurred. The ALJ also specifically noted in its order that the law places the burden of proof with DFCS.
Furthermore, the ALJ's statement that there was no evidence of consent immediately follows its finding that K.S. told Steiner to stop after the first time he "dry humped" her, and after Steiner did it again,
K.S. got off of him and walked away from him to make him stop. Thus, the statement that there was no evidence of consent is best understood in context with the preceding statements as a finding that the only evidence presented on the issue showed a lack of consent.14 Because there was some evidence to support the ALJ's finding that DFCS proved an act of child abuse as defined in the Act, the superior court erred in reversing the ALJ's finding on this issue.
Judgment reversed.
All the Justices concur.
