FRYE, Justice.
Plaintiffs bring this appeal from the order by Judge Stephens filed on 8 March 1990 which, among other things, granted defendants’ motion to dismiss plaintiffs’ complaint under Rule 12(b)(6), decided ex mero motu that plaintiffs’ complaint was dismissed for lack of subject matter jurisdiction, and declared that the contracts at issue are not invalid, unlawful, or otherwise unenforceable under North Carolina law. Plaintiffs raise three issues on appeal dealing with the constitutionality of the contracts between defendant Whittle Communications, L.P. (Whittle), and the various local school boards, as well as the validity of the temporary rule adopted by the State Board of Education concerning these contracts. We conclude that the State Board of Education did not have the authority to enact the temporary rule concerning the Whittle contracts because these contracts involve the selection and procurement of supplementary materials, an area which the General Assembly has specifically placed under the control and supervision of the local school boards. We further conclude that these contracts do not violate the North Carolina Constitution or the public policy of North Carolina.
Whittle, one of the defendants in this case, is a limited partnership which writes, publishes, and distributes, among other things, educational publications. In 1988, Whittle developed a short video news program, known as Channel One, which was designed to keep students informed on current affairs. Channel One would be [459]*459provided on a daily basis to the school systems which contracted with Whittle. The daily program is twelve minutes long, and two of the twelve minutes are commercial advertising. All of the video equipment needed to show the program is given to the contracting school systems to use for the duration of the system’s contract with Whittle.
Under the contract, Channel One would be broadcast to the individual schools at 6:00 a.m. each morning, and a staff member or committee at the school would preview the program to see if it was appropriate to be shown to the students. If appropriate, the program would be shown in its entirety during the school day. Students who do not wish to view the program would be allowed to do something else while the program was being shown to the rest of the school. The contract further provides that the program must be shown at the same time each school day and must be shown at least ninety-five per cent (95°/o) of the number of days on which the school is in session and the program is available in any calendar quarter. The contract requires the schools to keep detailed records as to when the program is shown and how many students are watching it.
Whittle made a presentation concerning Channel One to officials at the State Department of Public Instruction in July 1989 and began to make presentations to local school boards in the fall of 1989. The Davidson County Board of Education (Davidson), an intervenor defendant in this action, entered into a contract with Whittle on 29 January 1990, and the Thomasville City Board of Education (Thomasville), a defendant in this action, entered into a contract with Whittle on 8 February 1990.
The State Board of Education discussed Channel One at its regular January meeting and decided that it needed additional time to study the matter before its February meeting. On 1 February 1990, the State Board of Education adopted a temporary rule prohibiting local school boards from entering into a contract which
(1) Limits or impairs its authority and responsibility, or the authority and responsibility of administrators and teachers, to determine the materials to be presented to students during the school day; or
(2) Limits or impairs its authority and responsibility or the authority and responsibility of administrators and teachers, [460]*460to determine the times during the school day when materials will be presented to students.
N.C. Admin. Code tit. 16, r. 6D .0105 (February 1990). The rule further provided:
(b) Local boards of education are obligated to assure that students, as a consequence of the compulsory attendance laws, are not made a captive audience for required viewing, listening to, or reading commercial advertising. Therefore, no local board of education may enter into any contract or agreement with any person, corporation, association or organization, pursuant to which students are regularly required to observe, listen to, or read commercial advertising.
Id.
When this temporary rule was adopted, the State Board of Education decided that it would not be made retroactive to existing contracts; rather the rule would prohibit new contracts and the renewal of the existing contracts. The Superintendent of Public Instruction forwarded a copy of the new rule along with appropriate certification to the Office of Administrative Hearings (OAH) as a temporary rule effective immediately.
On 15 February 1990, the Administrative Rules Review Commission (Commission) met and considered the temporary rule passed by the State Board of Education on 1 February 1990. This Commission wrote a letter dated 16 February 1990 to the State Board of Education informing the Board that the Commission objected to the temporary rule “due to a lack of authority for use of the temporary rulemaking procedure and lack of statutory authority for the rule.” The Commission explained further that the State Board did not have the authority to make this temporary rule because “the execution of the commercial contracts prohibited by the rule did not pose either a serious or unforeseeable threat to public welfare.”
Defendant Thomasville signed a contract with Whittle, as noted earlier, on 8 February 1990, which was after the State Board of Education had enacted its temporary rule prohibiting new contracts after 1 February 1990. In a special session on 19 February 1990, the State Board of Education met and voted to amend the rule adopted 1 February 1990 in order to make the rule retroactive to existing contracts. The Superintendent of Public Instruction filed [461]*461this amendment and proper certification with the OAH as a temporary rule effective immediately.
On 19 February 1990, the State Board of Education voted to file this action against Whittle and Thomasville. The Superintendent of Public Instruction and the State of North Carolina joined the State Board of Education in filing this action which asked the court to declare void and unenforceable the contract entered into by Whittle and Thomasville on the grounds that the contract was contrary to the rules adopted by the State Board of Education, was contrary to public policy, and violated the North Carolina Constitution. The complaint filed by plaintiffs further sought to enjoin Thomasville and Whittle from implementing their contract and to enjoin Whittle from contracting with other local school boards in North Carolina.
On 19 February 1990, the State Board of Education also filed a motion for a temporary restraining order enjoining defendants from implementing the contract made by them on 8 February 1990. The motion for the temporary restraining order was granted that same day with a hearing on a preliminary injunction set for 1 March 1990. The 19 February 1990 order granting the temporary restraining order was vacated in an order filed 26 February 1990 because the original order failed to comply with Rule 65 of the Rules of Civil Procedure.
Whittle and Thomasville filed answers and counterclaims on 23 February 1990. The counterclaim asked: (1) that the court declare the contract executed by Whittle and Thomasville to be valid and enforceable; (2) that the court declare the action of the State Board of Education in adopting the temporary rule on 1 February 1990 and amending it on 19 February 1990 to be unlawful, unconstitutional, and in violation of the State Board’s own rules; and (3) that the court permanently enjoin the State Board of Education from enforcing this rule. Davidson filed a motion to intervene in this action as a defendant-counterclaimant, and this motion was allowed without objection.
On 16 February 1990, Thomasville and Whittle filed a verified petition for a contested case hearing and application for stay of agency action, temporary restraining order, and preliminary injunction with the OAH. These parties filed an amended verified petition for a contested case hearing, application for stay of agency action, and preliminary injunction on 27 February 1990. On 28 February [462]*4621990, plaintiffs filed a petition in superior court for writ of certiorari and writ of supersedeas and a motion to consolidate the administrative proceeding with the complaint which was filed on 19 February 1990. Defendants Thomasville and Whittle filed a response to plaintiffs’ motion asking that the superior court deny plaintiffs’ motion since jurisdiction of this matter had already attached in the OAH. These matters were all consolidated and were the subject of Judge Stephens’ March 1990 order from which plaintiffs now appeal.
The 8 March 1990 order adjudged and decreed:
(1) Defendant-Counterclaimants’ motion to dismiss the Complaint under Rule 12(b)(6) is allowed; and, the Court on its own motion dismisses the Complaint and the counterclaim under Rule 12(b)(1) for lack of subject matter jurisdiction.
(2) Plaintiffs’ petition for certiorari to review Administrative Law Judge Gray’s February 27, 1990 order is allowed and such order is vacated.
(3) Upon Judicial Review under G.S. § 150B, Article 4, of the validity of the temporary rule of February 1,1990, as amended and promulgated by the North Carolina State Board of Education, the Court holds such rule to be invalidly adopted in violation of the provisions of Article 2, G.S. § 150B and declares such rule to be void.
(4) The Court concludes that the contracts which are the subject of these proceedings are not invalid, are not unlawful and are not otherwise unenforceable under North Carolina law.
Plaintiffs filed notice of appeal to the Court of Appeals on 8 March 1990 and then filed a petition on 24 April 1990 with this Court for discretionary review prior to determination by the Court of Appeals. This petition was allowed on 10 May 1990. Plaintiffs raise three issues in this appeal: (1) whether the trial court erred in determining ex mero motu that it lacked subject matter jurisdiction over the complaint; (2) whether the trial court erred in failing to find that Whittle’s contract is contrary to public policy and the North Carolina Constitution and therefore void; and (3) whether the trial court erred in holding that rules adopted by the State Board of Education on 1 February 1990 were not binding on defendant Thomasville. We conclude that the State Board of [463]*463Education did not have the authority to promulgate a temporary rule governing this contract because the contract involves supplementary materials, an area which the General Assembly has delegated to the local school boards to oversee. See N.C.G.S. § 115C-98(b) (1987). We further conclude that this contract does not violate the North Carolina Constitution and is not contrary to public policy.
We first address plaintiffs’ contention that the trial court erred in determining ex mero motu that it lacked subject matter jurisdiction over the complaint. In their complaint plaintiffs sought the aid of the court in enforcing the State Board’s rules and also sought a declaration that certain contracts were void and unenforceable as against public policy and the North Carolina Constitution. Clearly the superior court is the proper forum for resolving the matters set forth in the complaint. See N.C.G.S. § 7A-245 (1989). There is no requirement that the agency must exhaust any administrative remedies before seeking the court’s help in enforcing an administrative rule adopted by that agency or in seeking a declaration that contracts adopted in violation of the agency’s rule are contrary to public policy or the constitution. Thus, we agree with plaintiffs that the trial court erred in dismissing the complaint on grounds that the court lacked subject matter jurisdiction. However, a review of the remaining conclusions in the trial court’s order clearly demonstrates that the trial court correctly exercised subject matter jurisdiction over plaintiffs’ complaint and decided the issues raised before it. Thus, plaintiffs received what they sought —a full adjudication of the issues raised in the complaint — and the trial court’s error in dismissing for lack of subject matter jurisdiction had no effect on plaintiffs. Since the trial court correctly fully adjudicated the issues before it prior to deciding to dismiss the complaint for lack of subject matter jurisdiction and these issues are now properly before us on appeal, the trial court’s error was harmless.
We now turn to issue three in which plaintiffs contend that the trial court erred in holding that the temporary rule adopted by the State Board of Education on 1 February 1990 was not binding on defendant Thomasville. Plaintiffs contend the trial court incorrectly concluded both that the State Board of Education is subject to the Administrative Procedure Act (APA) found in N.C.G.S. § 150B and that the State Board of Education’s actions in adopting the temporary rule on 1 February 1990 did not comply with the specific requirements for promulgating a temporary rule found in [464]*464N.C.G.S. § 150B-13. Plaintiffs assert that this temporary rule was promulgated under the authority granted to the State Board of Education by art. IX, § 5, of the North Carolina Constitution which provides in part:
The State Board of Education shall supervise and administer the free public school system . . . and shall make all needed rules and regulations in relation thereto, subject to laws enacted by the General Assembly. “
N.C. Const, art. IX, § 5. Plaintiffs cite Guthrie v. Taylor, 279 N.C. 703, 185 S.E.2d 193 (1971), for the proposition that where the General Assembly has not acted to limit the power of the State Board to adopt rules on a particular subject this power is limited only by other provisions in the Constitution. According to plaintiffs, the APA rulemaking requirements only apply to rules implementing statutes, and the temporary rule promulgated on 1 February 1990 was not implementing a statute; rather the rule was implementing the North Carolina Constitution’s grant of authority to the State Board found in art. IX, § 5. However, we do not have to decide whether plaintiffs’ assessment is correct because at the time this temporary rule was promulgated, N.C.G.S. § 115C-98(b) was in effect and directly spoke to this issue.
Article IX, § 5 of the North Carolina Constitution, which grants the State Board the authority to “make all needed rules,” also limits this authority by making it “subject to the laws enacted by the General Assembly.” Thus, we must examine our statutes to ascertain whether the General Assembly has enacted laws which would limit the power of the State Board in the area of selection of materials such as Channel One which we conclude is a supplementary instructional material. To fully answer this question, we look to the statutory treatment of selection and procurement of supplementary instructional materials.
In 1969, the General Assembly enacted chapter 519 entitled “An act to amend and revise Articles 25 and 26 of Chapter 115 of the General Statutes to authorize county and city BOARDS OF EDUCATION TO PROVIDE FOR THE SELECTION AND PROCUREMENT OF SUPPLEMENTARY TEXTBOOKS, LIBRARY BOOKS, PUBLICATIONS, AND OTHER INSTRUCTIONAL MATERIALS FOR THE PUBLIC SCHOOL [465]*465SYSTEM.” 1969 N.C. Sess. Laws ch. 519, § l.1 Chapter 519 created Article 25A entitled “Textbooks and Instructional Materials,” which outlined the procedures to be used for the adoption of textbooks and supplementary instructional materials. A fair reading of the statutory scheme reveals that while local school boards may only select textbooks from a list approved by the State Board, the selection of supplementary instructional materials is left entirely to the discretion of local school boards. In the preamble to chapter 519, the General Assembly provided an explanation for the adoption of Article 25A. As for the selection of supplementary materials, this preamble specifically provided: “it is desirable that the selection of supplementary instructional materials be made by each school administrative unit . . . .” Id.
With only minor differences, N.C.G.S. § 115-206.14(b), which was codified in 1969 in chapter 519, is identical to N.C.G.S. § 115C-98(b) which was in effect at the time the State Board of Education enacted the temporary rule in question. Section 115C-98(b) provides in part:
Local boards of education shall adopt written policies concerning the procedures to be followed in their local school administrative units for the selection and procurement of supplementary textbooks, library books, periodicals, and other instructional materials needed for instructional purposes in the public schools of their units.
N.C.G.S. § 115C-98(b) (1987). When N.C.G.S. § 115-206.14(b) was enacted, the General Assembly also enacted § 115-206(13), presently found at § 115C-97, which authorized the State Board of Education to discontinue handling supplementary books and other supplementary instructional materials. See N.C.G.S. § 115C-97 (1987).
As noted earlier, chapter 519, which was codified as Article 25A of the General Statutes, set out the procedures for adoption [466]*466of textbooks as well as supplementary instructional materials. The General Statutes clearly provide that the State Board of Education is to adopt textbooks. See N.C.G.S. § 115C-86 (1987). Section 115-106.14(a), now codified at § 115C-98(a), directed the local school boards to adopt rules and regulations concerning the local operation of the textbook program, but these rules and regulations were not to be “inconsistent with the policies of the State Board of Education concerning the local operation of the textbook program.” N.C.G.S. § 115C-98(a) (1987).
The General Statutes do not contain a similar direction to the State Board of Education for the adoption of supplementary instructional materials. The only statute which speaks to this issue is N.C.G.S. § 115C-98(b) which directs each local school board to adopt “written policies concerning the procedures” used in the adoption of supplementary instructional materials in its own unit. N.C.G.S. § 115C-98(b) (1987). Furthermore, this statute contains no limitation on the local school boards’ directive to adopt these written policies on supplementary instructional materials similar to the limitation concerning the local adoption of rules dealing with the local operation of the textbook program found in § 115C-98(a). The only limitation found in section (b) of the statute concerning supplementary instructional materials is that these “materials shall neither displace nor be used to the exclusion of basic textbooks.” N.C.G.S. § 115C-980») (1987). Thus, the General Assembly, by adopting chapter 519 in 1969, placed the decision-making process for the selection and procurement of these supplementary instructional materials in the exclusive domain of the local school boards while clearly making the rules adopted by the local boards concerning textbooks subject to the policies of the State Board. This legislative policy of allowing local school boards to have control over the adoption and procurement of supplementary instructional materials has remained undisturbed since its enactment by the General Assembly in 1969.
Since Channel One is a supplementary instructional material and since the General Assembly placed the procurement and selection of supplementary instructional materials under the control of the local school boards, the State Board acted in excess of its authority in enacting this rule because the State Board had no authority to enact a rule on this subject. Thus, deciding whether the State Board had the authority, absent legislative action, to enact this rule through direct constitutional authority and deciding [467]*467whether the APA provisions concerning the adoption of temporary rules apply are not necessary to a resolution of this issue.
We further note that if there was any doubt as to whether materials which involved commercial advertising in general were included in the provision of § 115C-98(b) as it existed at the time the temporary rule was adopted, the 1990 Session of the North Carolina General Assembly removed the doubt by amending this statute and providing that the local school boards have the authority to contract for materials containing commercial advertising without the approval of the State Board. In its amended form the statute now provides:
(b) Local boards of education shall adopt written policies concerning the procedures to be followed in their local school administrative units for the selection and procurement of supplementary textbooks, library books, periodicals, audio-visual materials, and other supplementary instructional materials needed for instructional purposes in the public schools of their units.
Local boards of education shall have sole authority to select and procure supplementary instructional materials, whether or not the materials contain commercial advertising, to determine if the materials are related to and within the limits of the prescribed curriculum, and to determine when the materials may be presented to students during the school day. Supplementary materials and contracts for supplementary materials are not subject to approval by the State Board of Education.
Supplementary books and other instructional materials shall neither displace nor be used to the exclusion of basic textbooks.
N.C.G.S. § 115C-98(b) (Cum. Supp. 1990) (emphasis added reflects the 1990 amendments).
Section 115C-47 which enumerates the powers or duties of the local boards of education was also amended by the 1990 Session to add:
(33) Local boards of education shall have sole authority to select and procure supplementary instructional materials, whether [468]*468or not the materials contain commercial advertising, pursuant to the provisions of G.S. 115C-98(b).
N.C.G.S. § 115C-47(33) (Cum. Supp. 1990).
These amendments were enacted as a part of the “Capital Improvement Appropriations Act of 1990” and became effective 1 July 1990. See 1989 N.C. Sess. Laws (Reg. Sess. 1990) ch. 1074. These amendments clearly provide that the local school boards have the power, without the need of approval of the State Board of Education, to select and contract for supplementary materials, including those which contain commercial advertising such as the contracts at issue in this case. See N.C.G.S. § 115C-98(b) and -47(33) (Cum. Supp. 1990). Through these amendments the General Assembly made clear what the statutes already provided — that decisions concerning the procurement of supplementary instructional materials, including those which involve commercial advertising, are to be made exclusively by the local school boards without having to seek approval of the State Board. Thus, the State Board had no authority to make rules regarding supplementary instructional materials, an area which was and still is under the supervision of the local school boards rather than the State Board. Therefore, the trial court did not err in holding that the temporary rule adopted by the State Board on 1 February 1990 was not binding on defendant Thomasville.
We now turn to plaintiffs’ remaining issue concerning whether Whittle’s contract is void because it violates the North Carolina Constitution and is contrary to public policy. We will first consider plaintiffs’ constitutional arguments and then address the public policy argument.
Plaintiffs claim that the contract violates both article V, § 2(1) and article IX, § 2(1) of the North Carolina Constitution. Article V, § 2(1) provides: “[t]he power pf taxation shall be exercised in a just and equitable manner, for public purposes only, and shall never be surrendered, suspended, or contracted away.” N.C. Const, art. V, § 2(1). Article IX, § 2(1) provides in part: “[t]he General Assembly shall provide by taxation and otherwise for a general and uniform system of free public schools.” N.C. Const. art. IX, § 2(1).
Plaintiffs contend that the “public purposes only” limitation of article V, § 2(1) is violated when tax dollars are used, directly or indirectly, to subsidize private business. Plaintiffs claim that the Whittle contract violates this public purpose limitation under [469]*469the North Carolina Constitution because tax dollars are being spent under this contract to further Whittle’s business and because the purpose of the contract is to further Whittle’s private business and the business of the commercial sponsors of Channel One. Plaintiffs claim that tax dollars are being spent to further private enterprise through this contract because tax funds are being spent to pay for buses and gasoline to get the students to school every day and to pay the salaries of the teachers who supervise the students while they watch the program during the school day. Plaintiffs perform some mathematical computations and reach the conclusion that the contract with Whittle is costing taxpayers “roughly four million dollars per school year,” based on the amount of time students spend watching the program and the amount of tax money spent to maintain the public schools.
Plaintiffs cite no authority for their contention that this contract results in the expenditure of tax money, and we find no authority which supports their contention. Aside from the money which is spent to furnish the electricity to run the machinery required for showing the Channel One program, which would be nothing more than a de minimis expenditure, we see no expenditures of tax money for showing the program. The contract provides that Whittle will furnish all of the equipment necessary to show the program, and the school system only provides the records showing the number of days the program is shown and the number of students watching it. The money spent for running buses and paying teachers is the same amount that would be spent if the local school board did not contract with Whittle to show Channel One-, no further tax money is being expended to support this contract. Thus, plaintiffs’ original premise that tax money is being spent to subsidize private business is incorrect. Since no tax money is being spent for the program, article V, § 2(1) is not applicable to this situation, and we need not address whether the expenditure of tax money is for a “public purpose” as required by the North Carolina Constitution. See N.C. Const, art. V, § 2(1). Therefore, we conclude that the contract does not violate article V, § 2(1).
Plaintiffs also contend that the contract violates the requirement for a “general and uniform system of free public schools” found in article IX, § 2(1) of the North Carolina Constitution. According to plaintiffs, the equipment provided by Whittle to the schools is not free because students pay for it with the time they spend watching commercial advertising for Whittle’s financial benefit [470]*470and the benefit of the Channel One advertisers. Citing Sneed v. Greensboro Board of Education, 299 N.C. 609, 264 S.E.2d 106 (1980), plaintiffs argue that charging students in time rather than in dollars is per se an unreasonable charge within the meaning of Sneed.
The plaintiffs in Sneed contended that the incidental course and instructional fees charged by the local school board violated the constitutional provision requiring free public schools. Id. at 612, 264 S.E.2d at 110. This Court concluded that there was “no constitutional bar to the collecting by our public schools of modest, reasonable fees for the purpose of enhancing the quality of their educational effort.” Id. at 610, 264 S.E.2d at 108. The fees involved in Sneed ranged from $4 to $7 per semester, and the Court viewed these fees as “reasonable and their burden de minimis.” Id. at 617 n.5, 264 S.E.2d at 113 n.5.
Sneed does not provide any authority for the proposition that charging students in time is the same thing as charging them in dollars, and plaintiffs provide no authority for their contention that the students are being “charged” to watch Channel One by the time they spend watching the program. Furthermore, the contract clearly provides that students are not required to watch the program, and the students do not have to “spend their time” watching the program if they do not wish to do so. Therefore, any comparison to Sneed is lost because Sneed involved mandatory fees, and watching Channel One is not mandatory. We do not find convincing plaintiffs’ argument that students are being made to pay for the contract through their time spent in watching the program, and we reject this argument. We conclude that the contract does not violate article IX, § 2(1).
Plaintiffs also contend that the contract violates the public policy of the State and is therefore void. The general rule in North Carolina is that absent “constitutional restraint, questions as to public policy are for legislative determination.” Gardner v. North Carolina State Bar, 316 N.C. 285, 293, 341 S.E.2d 517, 522 (1986) (citing Martin v. Housing Authority, 277 N.C. 29, 175 S.E.2d 665 (1970)). In the present case the legislature spoke specifically to this issue when it amended N.C.G.S. § 115C-98(b) and added N.C.G.S. § 115C-47(33) which were set out earlier in this opinion. Both sections give local school boards the authority, without seeking approval of the State Board of Education, to enter into contracts for supplementary instructional materials which involve commercial [471]*471advertising. See N.C.G.S. § 115C-98(b) and -47(33) (Cum. Supp. 1990). These amendments are an expression oí the legislature regarding the public policy of this State on this matter.
“Whether the public policy established by [these provisions of the statutes] is wise or unwise is for determination by the General Assembly” unless the statute is determined to be unconstitutional. Martin v. Housing Authority, 277 N.C. at 41, 175 S.E.2d at 672 (citations omitted). The General Assembly has set the public policy in the present situation so that the State Board of Education does not have any authority over the contracts which local school boards may enter into concerning the purchase of supplementary instructional materials even if these materials involve commercial advertising. In this appeal, plaintiffs have not challenged the constitutionality of these amendments to the statutes, and we have already determined that the contract itself does not violate article V, § 2(1) or article IX, § 2(1) of the North Carolina Constitution. Under these circumstances, we will not second-guess the General Assembly’s statement of public policy as set out in these amendments to the statutes. See Martin v. Housing Authority, 277 N.C. at 41, 175 S.E.2d at 671-72.
For the reasons set out above, we conclude that the trial court had subject matter jurisdiction over plaintiffs’ complaint and did not err in declaring that the Whittle contract does not violate the North Carolina Constitution or public policy. We further conclude that the State Board did not have authority to promulgate the temporary rule of 1 February 1990. For these reasons, we affirm the trial court’s order dismissing plaintiffs’ complaint.
Affirmed.
