OPINION
BACKGROUND
{1} Plaintiffs filed a complaint in district court seeking a declaratory judgment against the New Mexico Environmental Improvement Board (EIB). Plaintiffs argued that EIB lacked statutory authority under New Mexico law to promulgate certain regulations relating to automobile emissions. See 20.2.88.2 to 20.2.88.112 NMAC (12/31/2007) (adopting automobile emission standards for new vehicles in accordance with California code of regulations, Title 13). According to Plaintiffs, certain state statutes prohibited EIB from adopting those regulations, and Plaintiffs requested declaratory and injunctive relief to that effect from the court. See NMSA 1978, § 74-2-5(C)(l)(a) (2007) (EIB regulations shall be no more stringent than required by federal law); § 74-2-5(D) (vehicle emission regulations shall be consistent with federal law). Plaintiffs filed no claims under federal law.
{2} Plaintiffs elected not to participate in EIB administrative proceedings pertaining to the issuance of those regulations. Instead, they filed this lawsuit directly in district court, claiming that it presented a pure question of law, challenging not the wisdom of those regulations, but EIB’s authority under state law to even consider them. The district court dismissed the complaint on procedural grounds; namely, that Plaintiffs had to pursue an administrative appeal to the Court of Appeals, under NMSA 1978, Section 74-2-9 (1992) from the EIB proceedings, and could not file a separate declaratory judgment action in the district court.
{3} The Court of Appeals reversed, applying this Court’s recent opinion in Smith v. City of Santa Fe,
{4} We granted certiorari, and now affirm the Court of Appeals in all respects regarding the use of declaratory judgment to test the statutory authority of EIB to issue these automobile emissions regulations under state law. The Court of Appeals correctly applied our holding in Smith, and we adopt the stated reasoning so well articulated in that opinion. We agree that Smith authorizes the use of declaratory judgment in this instance to raise a purely legal challenge to EIB’s statutory authority, and that Plaintiffs may file for declaratory relief independent of the administrative appeal process. Accordingly, we remand this case in its entirety to the district court to decide the issues raised in Plaintiffs’ declaratory judgment action.
{5} Having clarified our support for the Court of Appeals opinion, we write solely to address one remaining issue pertaining to common law sovereign immunity. The Court of Appeals stated that, “Nevertheless, declaratory judgment actions are not without limit. For example, declaratory judgments are not permitted against the state unless the state has specifically consented to suit or waived its sovereign immunity.” Hanosh,
DISCUSSION
{6} We begin our discussion with Gill, in which this Court explored the contours of constitutional sovereign immunity as that principle has emerged in U.S. Supreme Court opinions over the past 15 years or so.
{7} Common-law sovereign immunity on the other hand, being a creation of the common law, is court-made law. As this Court made clear in Hicks, courts are very much able to expand, contract, or eliminate altogether common-law sovereign immunity, subject of course to the power of the state legislature to codify immunity in its place.
{8} Both Gill and Cockrell arose from federal statutes that created enforceable rights against the states; both cases asked whether the state had constitutional sovereign immunity from suit without its consent. In Gill, the plaintiff sought to infer such consent from the New Mexico Declaratory Judgment Act. NMSA 1978, §§ 44-6-1 to-15 (1975). Correctly, this Court responded in the negative. Importantly, however, whatever we said in Gill, limiting the use of declaratory judgment actions against the state without its consent, arose solely in the context of constitutional sovereign immunity. Neither Gill nor Cockrell arose from or had any effect upon common-law actions under state law or whether the state could be sued at common law without its consent. Indeed, in Gill, this Court authorized a suit for prospective injunctive or declaratory relief against state officials to vindicate federally-created rights with or without the consent of the state.
{9} In contrast, the present action for declaratory judgment makes no claim under federal law or asserts any right to sue the state under federal law. The present action leaves the state’s constitutional sovereign immunity intact. The present declaratory action arises solely under state statute, and the defense of sovereign immunity is asserted, not under federal law or principles of federalism, but under what EIB perceives to be vestigial remains of our state common-law sovereign immunity. Accordingly, any reliance on Gill by EIB, or by the Court of Appeals, is clearly in error.
{10} In New Mexico, of course, common-law sovereign immunity-as opposed to statutory immunity-has been repealed for over 30 years since this Court’s landmark decision in Hicks. Although that case specifically challenged the state’s common-law immunity from actions in tort, no one should doubt the broader scope of what this Court has previously described as “Hicks’s sweeping abolition of sovereign immunity.” Torrance County Mental Health Program, Inc. v. N.M. Health & Env’t Dep’t,
[t]he holding in Hicks, of course, was that the common law defense of sovereign immunity for claims in tort against the state would no longer (absent statutory authorization) be available, but we agree with [plaintiff] that the case generally abolished the common law doctrine of sovereign immunity in all its ramifications, whether in tort or contract or otherwise, except as implemented by statute or as might otherwise be interposed by judicial decision for sound policy reasons.
Id. (second emphasis added).
{11} Indicative of its broad scope, the Hicks opinion itself prefaced its holding by citing to a variety of New Mexico opinions and not just cases sounding in tort.
{12} Relief is appropriate for still another reason. In the event they are proven right on the law, Plaintiffs seek to hold a state agency accountable to statutory limitations allegedly imposed upon executive authority by the legislative branch. Such accountability goes to the heart of constitutional separation of powers, just as it is the exclusive province of the judicial branch to ascertain what the law is and afford appropriate relief. That relief certainly includes, in a proper case, the judiciary’s ability to define the law and injunction to enforce it. Anything less would encroach upon the constitutional powers reserved to the judiciary; anything less would place state agencies above the law. Whatever immunity of this kind executive agencies may have enjoyed in the past, belongs to the past.
CONCLUSION
{13} We affirm the Court of Appeals and remand to the district court for further proceedings.
{14} IT IS SO ORDERED.
