delivered the opinion of the court:
In these consolidated interlocutory appeals, we are asked to decide whether the circuit court has the authority under section 2 — 10 of the Juvenile Court Act of 1987 (705 ILCS 405/2 — 10(2) (West 1994)) to enter orders requiring the Department of Children and Family Services (DCFS) to provide and pay for in-patient drug treatment services for mothers whose children were removed from their custody due to their mothers’ drug-related neglect of them. On nine separate occasions in 1993 and 1994, DCFS appealed from the entry of such orders by the circuit court of Cook County, juvenile division (hereinafter juvenile court). The appellate court consolidated the appeals, and affirmed the juvenile court orders in all but two instances.1 269 Ill. App. 3d 253.
We allowed DCFS’s petition for leave to appeal. 155 111. 2d R. 315. Separate appellees’ briefs were filed by the office of the Cook County public guardian, on behalf of the minor children, and by the Cook County public defender, on behalf of the minors’ parents. "Appellees,” as used in this opinion, refers, interchangeably, to the minor children or to their parents. We granted leave to the Austin Christian Law Center; the Children and Family Justice Center of the Northwestern University School of Law; and Illinois Action for Children, the Legal Assistance Foundation of Chicago, and Joyce M. to file amicus curiae briefs in support of appellees. 155 Ill. 2d R. 345.
Initially we note that, in an interlocutory appeal, the scope of review is normally limited to an examination of whether or not the trial court abused its discretion in granting or, refusing the requested interlocutory relief. See Dixon Ass’n for Retarded Citizens v. Thompson, 91 Ill. 2d 518, 524 (1982); Kellerman v. MCI Telecommunications Corp., 134 Ill. App. 3d 71, 73 (1985), aff’d, 112 Ill. 2d 428 (1986). However, where the question presented is one of law, a reviewing court determines it independently of the trial court’s judgment. Best Coin-Op, Inc. v. Old Willow Falls Condominium Ass’n, 120 Ill. App. 3d 830 (1983). Moreover, to the extent necessary, a reviewing court may consider substantive issues in order to determine whether the trial court acted within its authority. See Wilson v. Wilson, 217 Ill. App. 3d 844, 859 (1991). In the instant, case, DCFS asserts that the juvenile court acted outside its authority in directing DCFS to pay for drug treatment services to the parents of minors before the court because such orders are barred by the doctrine of sovereign immunity, violate the doctrine of separation of powers, and are not authorized by the Juvenile Court Act of 1987 (705 ILCS 405/ 1 — 1 et seq. (West 1994)). Therefore, to the extent necessary to resolve these substantive issues, we are not limited to the traditional scope of review of an interlocutory appeal. See Dixon, 91 Ill. 2d at 524-25.
We first address the question of sovereign immunity in order to determine whether the juvenile court had subject matter jurisdiction. DCFS argues that the appellate court erred in holding that the juvenile court orders did not violate the doctrine of sovereign immunity, because each juvenile court order was directed to DCFS, a state agency, to compel the expenditure of state funds. We find little merit in this challenge. While sovereign immunity dictates that the state can be sued only in the Court of Claims, the determination of whether an action is in fact a suit against the state turns upon an analysis of the issues involved and the relief sought, rather than the formal designation of the parties. Currie v. Lao, 148 Ill. 2d 151, 157-58 (1992); Healy v. Vaupel, 133 Ill. 2d 295, 308 (1990).
In the present case, the juvenile court sought to compel DCFS, through Gary T. Morgan, its guardianship administrator and the appointed temporary custodian of each of the minors, or Carlton Williams, another DCFS administrator, to fulfill duties it believed were mandated by the Juvenile Court Act. A suit against state officials which seeks to compel them to perform their duty is not held to be a suit against the state even though the duty to be performed arises under a certain statute, and the payment of state funds may be compelled. See In re V.H., 197 Ill. App. 3d 52, 58 (1990); Franks v. Tucker, 132 Ill. App. 3d 455, 461 (1985). Therefore, the appellate court did not err in finding that the juvenile court orders at issue here were not barred by the doctrine of sovereign immunity, where the orders essentially directed DCFS administrators to provide mandated services. 269 Ill. App. 3d at 256-57.
DCFS also contends that the juvenile court orders violated the doctrine of separation of powers because the juvenile court usurped the authority of DCFS to determine the proper services to be provided for the families involved herein. The separation of powers clause provides: "The legislative, executive and judicial branches are separate. No branch shall exercise powers properly belonging to another.” Ill. Const. 1970, art. II, § 1. However, the doctrine of separation of powers was not designed to achieve a complete divorce among the three branches of government, nor does it require governmental powers to be divided into rigid, mutually exclusive compartments. In re J.J., 142 Ill. 2d 1, 7 (1991). There are instances in which the separate spheres of governmental authority overlap (In re J.J., 142 Ill. 2d at 7), and this is an excellent example of one of them.
The legislature has designated DCFS as the state agency authorized to provide social services to children and their families which are directed toward, inter alia, "preventing or remedying, or assisting in the solution of problems which may result in, the neglect, abuse, exploitation or delinquency of children.” 20 ILCS 505/1, 5(a)(3)(B) (West 1994). However, the legislature has also authorized the juvenile court, in dealing with a minor it has probable cause to believe is abused, neglected or dependent, to enter orders for the "provision of services to the minor or his family to ameliorate the causes contributing to the finding of probable cause.” 705 ILCS 405/2 — 10(2) (West 1994). Therefore, the "evil” of the court’s usurping the executive discretion of DCFS in providing child welfare services is absent in abuse and neglect proceedings, where both DCFS and the court share the duty of protecting the child’s best interest and the goal of preserving families whenever possible. See In re J.J., 142 Ill. 2d at 8-9; see also 325 ILCS 5/2; 20 ILCS 505/5(a)(3)(C), (a)(3)(D); 705 ILCS 405/2 — 10(2), (9)(d) (West 1994). Indeed, section 8.4 of the Abused and Neglected Child Reporting Act (325 ILCS 5/8.4 (West 1994)) requires that DCFS "provide or arrange for and monitor *** rehabilitative services for children and their families on a voluntary basis or under a final or intermediate order of the Court.” (Emphasis added.) Thus, where it is clear that the legislature contemplated interplay between DCFS and the juvenile court in deciding the appropriate social services for neglected and abused children and their families, the juvenile court orders involved herein did not violate the doctrine of separation of powers.
Having disposed of these preliminary matters, the central issue presented for our resolution remains: whether the juvenile court, pursuant to the Juvenile Court Act, may order DCFS to provide and pay for inpatient drug treatment services for mothers whose children are removed from their custody due to the mothers’ drug-related neglect of them. DCFS argues that the juvenile court has no authority to exercise a power not specifically granted to it by the Juvenile Court Act, and that because there is no statutory authority requiring that DCFS provide and pay for drug treatment services for the parents of minors, the juvenile court lacked subject matter jurisdiction to enter the orders in question. However, circuit court jurisdiction is conferred solely by the constitution, except in the limited area of administrative review. See 111. Const. 1970, art. VI, § 9; In re M.M., 156 Ill. 2d 53, 65 (1993). Therefore, contrary to DCFS’s assertion, circuit courts no longer seek statutory justification for the exercise of jurisdiction. See In re M.M., 156 Ill. 2d at 75 (Miller, C.J., concurring). Further, while it is true that the constitutional source of a circuit court’s jurisdiction does not carry with it a license to act in ways inconsistent with controlling statutory law (see In re M.M., 156 Ill. 2d at 75 (Miller, C.J., concurring)), we need not address that problem here because we believe the applicable statutory provisions support the juvenile court’s orders.
It is the purpose and policy of the Juvenile Court Act to preserve and strengthen the minor’s family ties, removing him from his family only when his welfare or safety or the protection of the public cannot be adequately safeguarded. 705 ILCS 405/1 — 2(1) (West 1994). More particularly, section 2 — 10 of the Juvenile Court Act (705 ILCS 405/2 — 10 (West 1994)), which pertains to temporary custody proceedings following the filing of a petition alleging that a minor is abused, neglected or dependent, is part of a comprehensive statutory scheme designed to, in a just and speedy manner, "determine families in need, reunify families where appropriate and, if reunification is inappropriate, find other permanent homes for children.” 705 ILCS 405/2 — 14(a) (West 1994). Section 2 — 10(2) of the Act provides, inter alia:
"If the minor is ordered placed in a shelter care facility of the Department of Children and Family Services or a licensed child welfare agency, the court shall, upon request of the appropriate Department or other agency, appoint the [DCFS] Guardianship Administrator or other appropriate agency executive temporary custodian of the minor and the court may enter such other orders related to the temporary custody as it deems fit and proper, including the provision of services to the minor or his family to ameliorate the causes contributing to the finding of probable cause or to the finding of the existence of immediate and urgent necessity.” (Emphasis added.) 705 ILCS 405/ 2 — 10(2) (West 1994).
Appellees argue that the plain language of this section grants the juvenile court the authority to enter orders for the provision of drug treatment services for parents whose addiction has caused or contributed to the minor’s placement in shelter care. We agree, not only because the Juvenile Court Act is to be liberally construed to carry out its purpose and policies (705 ILCS 405/1 — 2(4) (West 1994)), but more importantly, because other statutory provisions make it clear that drug treatment for parents of neglected and abused children was among the services the legislature intended DCFS to provide.
The parties agree that the Juvenile Court Act, the Abused and Neglected Child Reporting Act (325 ILCS 5/1 et seq. (West 1994)), the Children and Family Services Act (20 ILCS 505/1 et seq. (West 1994)), and, to some extent, the Illinois Alcoholism and Other Drug Dependency Act (20 ILCS 301/1 — 1 et seq. (West 1994)) must be construed in concert to determine the powers and responsibilities of DCFS in cases involving abuse or neglect resulting from parental drug abuse. Under the Abused and Neglected Child Reporting Act, once there is credible evidence that a child is abused or neglected, DCFS must promptly notify the child and his family of DCFS’s responsibility to offer and provide "family preservation services.’-’ 325 ILCS 5/8.2 (West 1994). Family preservation services are defined in that same section as "all services to prevent the placement of children in substitute care, to reunite them with their families if so placed and if reunification is an appropriate goal, or to maintain an adoptive placement.” 325 ILCS 5/8.2 (West 1994). Such services include, but are not limited to, case management services, homemaker, parent education, day care, medical assistance, and counseling, which specifically includes drug and alcohol abuse counseling. 325 ILCS 5/8.2 (West 1994).
The Children and Family Services Act states that DCFS shall have the power to provide direct child welfare services. 20 ILCS 505/5 (West 1994). Section 5(a)(3) provides, in part:
" 'Child welfare services’ means public social services which are directed toward the accomplishment of the following purposes:
(B) preventing or remedying, or assisting in the solution of problems which may result in, the neglect, abuse, exploitation or delinquency of children;
(C) preventing the unnecessary separation of children from their families by identifying family problems, assisting families in resolving their problems, and preventing the breakup of the family where the prevention of child removal is desirable and possible;
(D) restoring to their families children who have been removed, by the provision of services to the child and the families.” 20 ILCS 505/5(a)(3)(B) through (a)(3)(D) (West 1994).
Section 5 of the Children and Family Services Act further states: "Service programs shall be available throughout the State and shall include but not be limited to the following services: (1) case management; (2) homemakers; (3) counseling’, (4) parent education; (5) day care; and (6) emergency assistance and advocacy.” (Emphasis added.) 20 ILCS 505/56) (West 1994). Indeed, we find it worthy of note that section 5, which addresses in detail DCFS’s provision of direct child welfare- services, places no limitations on the expenditure of public funds save for the purpose of performing abortions. See 20 ILCS 50575(b) (West 1994). Rather, section 5(1) mandates that DCFS "accept for family preservation services, and *** provide appropriate services to, any family whose child has been placed in substitute care *** or any persons whose child or children are at risk of being placed outside their home” because of a report of suspected child abuse or neglect. 20 ILCS 505/5(1) (West 1994).
Additionally, section 34.4 of the Children and Family Services Act empowers DCFS "[t]o enter into referral agreements, on its own behalf and on behalf of agencies funded by [DCFS], with licensed alcohol and drug abuse treatment programs for the referral and treatment of clients with alcohol and drug abuse problems.” (Emphasis added.) 20 ILCS 505/34.4 (West 1994). While this language seems to indicate that DCFS may enter into agreements to fund substance abuse treatment of clients, DCFS argues that it is required by statute only to recommend and refer adult clients to other state agencies to obtain treatment. It is true that several statutory provisions allude to DCFS’s duty to recommend drug or alcohol abuse treatment and to include any treatment recommendations in the family’s case or service plan. See 20 ILCS 505/34.5; 325 ILCS 5/8.2 (West 1994). However, these provisions do not abrogate DCFS’s responsibility to provide and pay for drug and alcohol treatment services for parents who need these services to preserve their families. Indeed, we have found no statutory provisions which require DCFS to refer parents to other state agencies to obtain services; rather, only sections requiring DCFS to refer individuals to a licensed program or facility. See 20 ILCS 505/34.5; 325 ILCS 5/8.2 (West 1994).
DCFS also argues that under the Alcoholism and Other Drug Abuse and Dependency Act, the Department of Alcoholism and Substance Abuse (DASA) is the state agency responsible for paying for drug and alcohol treatment. However, we agree with the appellate court that,there is nothing to indicate that DASA is the exclusive state agency to provide substance abuse treatment. "Rather, DASA was designed to work with other State agencies in providing substance abuse treatment.” 269 111. App. 3d at 261; see 20 ILCS 301/5 — 10(a)(4)(I), (a)(14) (West 1994). The Alcoholism and Other Drug Abuse and Dependency Act provides, in its legislative declaration, that "[t]he human, social, and economic benefits of preventing alcohol and other drug abuse and dependence are great, and it is imperative that there be interagency cooperation in the planning and delivery of alcohol and other drug abuse prevention, intervention, and treatment efforts in Illinois.” (Emphasis added.) 20 ILCS 301/1 — 5 (West 1994).
Indeed, section 5 — 10(a)(4) of the Alcoholism and Other Drug Abuse and Dependency Act specifies that DASA is to work with DCFS to:
"(D) Assist in the placement of child abuse or neglect perpetrators (identified by the Illinois Department of Children and Family Services) who have been determined to be in need of alcohol or other drug abuse services pursuant to Section- 8.2 of the Abused and Neglected Child Reporting Act.
(E) Cooperate with and assist the Illinois Department of Children and Family Services in carrying out its mandates to:
(i) identify alcohol and other drug abuse issues among its clients and their families; and
(ii) develop programs and services to deal with such problems.
These programs and services may include, but shall not be limited to, programs to prevent the abuse of alcohol or other drugs by DCFS clients and their families, rehabilitation services, identifying child care needs within the array of alcohol and other drug abuse services, and assistance with other issues as required.” 20 ILCS 301/5— 10(a)(4)(D), (a)(4)(E) (West 1994).
Therefore, contrary to DCFS’s claim, the Alcoholism and Other Drug Abuse and Dependency Act, like the Juvenile Court Act, Abused and Neglected Child Reporting Act and the Children and Family Services Act, demonstrates the intent of our legislature to mandate DCFS’s provision of drug treatment services to parents involved in juvenile abuse and neglect proceedings as a result of their drug-related neglect of their children.
Finally, DCFS argues that the appellate court’s affirmance of the juvenile court orders was premised on the false assumptions that the orders were essential to the reunification of the families in question, entered after DCFS had been afforded adequate time to develop a treatment plan for the families, and interim in nature. We first note that our review of the record supports the appellate court’s finding that, in each of the instant cases, DCFS did not dispute the need for in-patient drug treatment, but simply claimed that it should not be required to pay for such treatment. 269 Ill. App. 3d at 258. Additionally, in all of the cases save one, where the record is unclear, the drug treatment was either recommended by DCFS itself or by a substance abuse professional. Therefore, we see no error in the appellate court’s finding that the orders were essential to the reunification of the families in question.
Next, we address DCFS’s contention that the juvenile court’s entry of orders for services prior to the filing of a case plan pursuant to section 2 — 10.1 of the Juvenile Court Act (705 ILCS 405/2 — 10.1 (West 1994)) is premature. DCFS claims that there was no time for it to investigate whether an in-patient drug treatment program would be appropriate for the mothers in question. However, a full review of the relevant statutes demonstrates that, in most cases, DCFS should have a treatment plan in development prior to the temporary custody hearing. Section 2 — 10(2) of the Juvenile Court Act provides that, at the time of the temporary custody hearing:
"The court shall require documentation from [DCFS] as to the reasonable efforts that were made to prevent or eliminate the necessity of removal of the minor from his or her home or the reasons why no efforts reasonably could be made to prevent or eliminate the necessity of removal.” 705 ILCS 405/2 — 10(2) (West 1994).
This language shows that DCFS must come to court with any and all documentation of its service provision efforts.
In addition, both the Abused and Neglected Child Reporting Act and the Children and Family Services Act address DCFS’s responsibility to create case plans and provide services to children and families while under investigation by DCFS and before juvenile court involvement. The Abused and Neglected Child Reporting Act states that when DCFS’s Child Protective Unit determines there is credible evidence to believe that the child is abused or neglected, DCFS "shall assess the family’s need for services, and, as necessary, develop, with the family, an appropriate service plan for the family’s voluntary acceptance or refusal.” 325 ILCS 5/8.2 (West 1994); see also 20 ILCS 505/34.5 (West 1994). Perhaps most significant is the provision in section 5(1) of the Children and Family Services Act that:
"[t]he child and his family shall be eligible for services as soon as the report [of suspected child abuse or neglect] is determined to be 'indicated’. The Department may offer services to any child or family with respect to whom a report of suspected child abuse or neglect has been filed, prior to concluding its investigation under Section 7.12 of the Abused and Neglected Child Reporting Act.” (Emphasis added.) 20 ILCS 505/5(1) (West 1994).
Additionally, a review of the record shows that DCFS did not argue in the juvenile court that entry of the orders was premature because it did not yet have the opportunity to complete a case plan. Rather, the record supports the appellate court’s finding that, in each of the cases, DCFS had sufficient time prior to the entry of the order to determine the family’s need for drug treatment services.
We also believe that the appellate court correctly found that the juvenile court did not impose a long-term obligation on DCFS. The record shows that the juvenile court was interested in giving these mothers an opportunity to reunite their families through successful completion of an in-patient drug treatment program and that the court "recognized the need to immediately place the mothers in *** treatment programs since at the time the children were removed from the home, the mothers were most motivated to cooperate in order to get their children back.” 269 111. App. 3d at 258. The orders at issue required DCFS to place the mothers in appropriate treatment facilities and to guarantee payment to those facilities. The orders did not prohibit DCFS from seeking funds from DASA or other sources to pay for the mothers’ treatment. See 20 ILCS 301/5— 10(a)(14) (West 1994); see also 20 ILCS 505/34.6; 325 ILCS 5/8.2(e),(f) (West 1994). Thus, contrary to DCFS’s contention, the record does indicate that the juvenile court viewed these orders as interim in nature.
Accordingly, we hold that the juvenile court is statutorily authorized to order DCFS to provide and pay for in-patient drug treatment services under the circumstances present herein, and that the orders entered were supported by the record and therefore not an abuse of the court’s discretion.
For the foregoing reasons, the judgment of the appellate court is affirmed.
Affirmed.
The appellate court reversed the juvenile court orders concerning Lawrence M., Christian M., Christopher M., and Garmon M. None of the parties seeks review of the appellate court’s ruling in those cases.
