OPINION
DIANE HENSON, Justice.
The State appellants challenge the award of attorneys' fees to the school district appellees (the Districts) in a suit for declaratory and injunctive relief under the Uniform Declaratory Judgments Act (UDJA) and article VII, § 1 and article VIII, § 1-e of the Texas Constitution.
Four Texas school districts, who were later joined by 43 additional districts (collectively, the West Orange-Cove Districts), initially brought suit against the State, claiming that the State's school-finance *866 system constituted a state property tax prohibited by article VIII, § 1-e and that the system failed to adequately provide for a general diffusion of knowledge as required by article VII, § 1. Two additional sets of school districts, the Edgewood Districts and the Alvarado Districts, intervened, also seeking declarations that the system violated article VII, § 1. The trial court found in favor of the Districts on all but one claim and awarded attorneys' fees to the Districts.
The State appealed directly to the Texas Supreme Court, which held that the school-finance system met the standards of article VII, § 1, but that it created a state property tax in violation of article VIII, § 1-e. The supreme court remanded the case to the trial court to reconsider the amount of attorneys' fees to be awarded. On remand, the trial court reinstated the original amount of attorneys' fees awarded to the West Orange-Cove Districts and awarded fees to the Edgewood and Alvarado Districts in a slightly reduced amount.
The State appeals the award of attorneys' fees to the Districts, claiming that the trial court abused its discretion in awarding attorneys' fees because (1) the relief sought by the Districts' declaratory-judgment claim was identical to that available directly under self-executing constitutional provisions and (2) the trial court did not properly account for the fact that the State prevailed in the Texas Supreme Court on all but one of the Districts' claims.

BACKGROUND
In 2001, the West Orange-Cove Districts, a group that was originally made up of four Texas school districts but has since grown to a coalition of 47 districts, filed a lawsuit claiming that the school-finance system's property tax cap of $1.50 per $100 resulted in a state property tax in violation of article VIII, § 1-e of the Texas Constitution.[1] The trial court dismissed the case, and that dismissal was affirmed by this Court, but the Texas Supreme Court reversed our judgment, remanding the case to allow the West Orange-Cove Districts to proceed with their claim. West Orange-Cove Consol. Indep. Sch. Dist. v. Alanis, 107 S.W.3d 558 (Tex.2003). The original four plaintiff districts were then joined by 43 additional districts, and the West Orange-Cove Districts amended their petition to include an adequacy claim, stating that the school-finance system prevented them from providing a "general diffusion of knowledge," in violation of article VII, § 1.[2] The Edgewood and Alvarado Districts intervened in the case, asserting adequacy claims and also including efficiency claims, arguing that the school-finance system was inefficient in violation of article VII, § 1. Each set of districts also sought attorneys' fees under the UDJA.
The trial court ruled in favor of the West Orange-Cove Districts on their claims for declaratory relief under article VII, § 1 and article VIII, § 1-e. The trial court also ruled in favor of the Edgewood and Alvarado Districts on their adequacy claims and their efficiency claims that were related to facilities funding, but ruled in favor of the State on the Edgewood and Alvarado Districts' efficiency claims related to maintenance and operations funding. In a separate, bifurcated proceeding, the *867 trial court awarded attorneys' fees to each set of Districts under the UDJA. See Tex. Civ. Prac. & Rem.Code Ann. § 37.009 (West 1997).
The State filed a direct appeal of the trial court's judgment to the Texas Supreme Court, but did not challenge the award of attorneys' fees.[3] The supreme court affirmed the trial court's article VIII, § 1 ruling, but ruled in favor of the State on the adequacy and efficiency claims. In light of these rulings, the supreme court remanded the case for reconsideration of the attorneys' fees award, stating, "[W]e reverse the award of attorney fees and remand the case to the district court to reconsider what award of attorney fees, if any, is appropriate. We express no opinion on this issue." Neeley v. West Orange-Cove Consol. Indep. Sch. Dist., 176 S.W.3d 746, 799 (Tex.2005).
On remand and after a hearing, the district court reinstated the West Orange-Cove Districts' award of $2,657,606.00 in attorneys' fees. The trial court awarded reduced amounts of $1,256,395.20 to the Edgewood Districts and $263,912.50 to the Alvarado Districts. Each set of districts was awarded post-judgment interest and conditional appellate fees.

STANDARD OF REVIEW
A trial court's judgment in granting or denying attorneys' fees in a declaratory-judgment action is reviewed for an abuse of discretion. Oake v. Collin County, 692 S.W.2d 454, 455 (Tex.1985). The trial court's judgment will not be reversed unless "the trial court abused its discretion by awarding fees when there was insufficient evidence that the fees were reasonable and necessary, or when the award was inequitable or unjust." Bocquet v. Herring, 972 S.W.2d 19, 21 (Tex.1998).

DISCUSSION
The State contends that the Districts are not entitled to attorneys' fees under the UDJA because a declaratory judgment may not be used solely as a vehicle to obtain attorneys' fees. The State argues that because articles VII and VIII are self-executing constitutional provisions, the Districts were limited to bringing direct claims under the Constitution and are therefore ineligible for attorneys' fees under the UDJA. However, the State did not assert this argument until after the case had been remanded to the trial court for reconsideration of the attorneys' fees award. The State did not argue that the Districts were precluded from an award of attorneys' fees in its direct appeal to the supreme court.
A party may not introduce an issue on remand that it failed to raise in previous appellate proceedings. See Miller v. University Sav. Ass'n, 858 S.W.2d 33, 36 (Tex.App.-Houston [14th Dist.] 1993, writ denied). Because the State had ample opportunity to contest the award of attorneys' fees in the direct appeal, "we will not permit a substantive argument of this nature to now be raised." Head Indus. Coatings & Servs., Inc. v. Maryland Ins. Co., 981 S.W.2d 305, 311 (Tex.App.-Texarkana 1998, pet. denied). The State is not exempt from the requirement that issues must be raised in appellate proceedings prior to remand. See Nations v. State, 944 S.W.2d 795, 799 (Tex.App.-Austin 1997, pet. ref'd) (holding that State waived argument about reliability of expert's *868 testimony when issue was first raised on remand).
The State argues that the propriety of the award of attorneys' fees was not within the direct-appeal jurisdiction of the Texas Supreme Court and that therefore the State's failure to assert the issue on direct appeal did not constitute a waiver. The Texas Supreme Court, however, may exercise jurisdiction over arguments ancillary to an issue over which it has direct-appeal jurisdiction. Edgewood Indep. Sch. Dist. v. Meno, 917 S.W.2d 717, 749 n. 39 (Tex.1995). When the supreme court has "appellate jurisdiction of any issue, it acquires `extended jurisdiction' of all other questions of law properly preserved and presented." Id. (quoting City of Corpus Christi v. Public Util. Comm'n, 572 S.W.2d 290, 294 (Tex.1978)). As a result, the State could have properly raised its argument that the Districts could not seek attorneys' fees under the UDJA on direct appeal to the Texas Supreme Court. Because the State failed to do so, the issue is waived and we need not reach the merits of whether the Districts' use of the UDJA was appropriate.
While the State has waived its argument that attorneys' fees should not be awarded to the Districts, we may review the trial court's award of attorneys' fees to ensure that the award is equitable and just. Bocquet, 972 S.W.2d at 21. A trial court's judgment regarding the award of attorneys' fees "will not be reversed on appeal absent a clear showing that [the trial court] abused [its] discretion." Oake, 692 S.W.2d at 455.
The record reflects that each set of Districts made significant contributions in what turned out to be a highly complex lawsuit that required large amounts of statistical and demographic data. The contributions of each set of Districts were essential to the litigation as a whole, including the claim that ultimately prevailed. Furthermore, as the trial court noted in the April 11, 2006 hearing on attorneys' fees, "[i]f it weren't for this case . . . I'm not sure the State leaders in the legislative branch would be as active as they are at problem-solving these dire problems. And to that extent, the litigation is absolutely necessary and indispensable." We hold that the award of attorneys' fees to each of the Districts was equitable and just, in light of the fact that the Districts were required to pursue extensive and costly litigation in order to remedy a school-finance problem with statewide implications.
The State argues that the trial court abused its discretion in awarding attorneys' fees to parties that did not prevail on their claims. However, "the award of attorneys' fees in declaratory judgment actions is clearly within the trial court's discretion and is not dependent on a finding that a party `substantially prevailed.'" Barshop v. Medina County Underground Conservation Dist., 925 S.W.2d 618, 637 (Tex.1996). As a result, we hold that the trial court did not abuse its discretion by awarding attorneys' fees to nonprevailing parties.
The State also contends that if attorneys' fees are awarded to the Districts, such awards should be offset by the State's fees related to claims in which the State prevailed. The State has not provided this Court with any authority for using such a method of calculating the amount of attorneys' fees to be awarded. The trial court is free to consider the relative success of the parties when determining the amount of the Districts' attorneys' fees. Mercier v. Southwestern Bell Yellow Pages, Inc., 214 S.W.3d 770, 776 (Tex. App.-Corpus Christi 2007, no pet.). There is no evidence suggesting that the trial court did not make such a consideration in determining the amount of attorneys' fees *869 to award on remand. Furthermore, as noted above, whether or not a party prevails on its claim is not determinative in the decision to award attorneys' fees for declaratory-judgment actions. See Barshop, 925 S.W.2d at 637. As a result, we hold that the State's argument for offsetting the award of attorneys' fees is without merit.

CONCLUSION
Because the State waived its argument regarding the propriety of the attorneys' fees awarded by not asserting it on direct appeal to the Texas Supreme Court and because the awards were equitable and just, the trial court's judgment awarding attorneys' fees is affirmed.
