OPINION AND ORDER
¶1 This is an appeal by Plan Helena, Inc. and Alan Nicholson (collectively, Plan Helena) from two orders of the First Judicial District Court, Lewis and Clark County. In the first, dated March 18,2009, the *143 District Court granted summary judgment in favor of Helena Regional Airport Authority Board (HRAA) and Lewis and Clark County (the County). In the second, dated May 13,2009, the District Court denied Plan Helena’s motion to alter or amend the court’s March 18 order.
¶2 We conclude that this case does not present a case or controversy, but rather calls for an advisory opinion. Accordingly, we vacate the District Court’s two orders, dismiss this appeal, and remand for entry of an order dismissing the case as nonjusticiable.
BACKGROUND
¶3 By way of a brief background, HRAA owns approximately 1,300 acres of land. In October 2008, Plan Helena filed suit against HRAA to enjoin and declare unlawful HRAA’s proposed lease of nine acres of this land to Blue Cross Blue Shield of Montana (BCBS). The lease was intended to cover land adjacent to the Helena Regional Airport and to remain in effect for 40 years. Plan Helena contended that the proposed lease violated § 67-11-232, MCA. Ultimately the litigation involved the interpretation of § 67-11-232, MCA, along with § 67-11-211, MCA, and other statutes in the Airport Authorities Act (Title 67, chapter 11, MCA). The District Court framed the precise question before it as “what statutory scheme governs the lease of property owned by [HRAA] to private commercial businesses whose activities are not specifically aeronautically related?”
¶4 BCBS was permitted to intervene in November 2008. In December 2008, HRAA commenced a separate proceeding for declaratory judgment, and that suit was later consolidated with Plan Helena’s suit. In February 2009, the County was permitted to intervene, and it has remained a party in this case.
¶5 Critical to our decision here, BCBS ultimately determined not to go through with the lease and was dismissed from this case in February 2009 shortly before a hearing on the parties’ cross-motions for summary judgment. The District Court posited that BCBS’s decision would render the matter moot; however, the parties desired a ruling on the merits, and the court thus proceeded to issue the orders now before us on appeal, essentially giving an advisory opinion as to the applicability of the above statutes.
DISCUSSION
¶6 The judicial power of Montana’s courts, like the federal courts, is limited to “justiciable controversies.”
See Greater Missoula Area Fedn. v. Child Start, Inc.,
¶7 The United States Supreme Court has explained that the words “cases” and “controversies” embody two complementary but somewhat different limitations:
In part those words limit the business of federal courts to questions presented in an adversary context and in a form historically viewed as capable of resolution through the judicial process. And in part those words define the role assigned to the judiciary in a tripartite allocation of power to assure that the federal courts will not intrude into areas committed to the other branches of government. Justiciability is the term of art employed to give expression to this dual limitation placed upon federal courts by the case-and-controversy doctrine.
Flast v. Cohen,
¶8 “A justiciable controversy is one upon which a court’s judgment will effectively operate, as distinguished from a dispute invoking a purely political, administrative, philosophical or academic conclusion.”
Clark v. Roosevelt County,
¶9 We consistently have held that this Court does not render advisory opinions.
See Serena Vista, LLC v. Dept. of Nat. Resources and Conserv.,
When the federal judicial power is invoked to pass upon the validity of actions by the Legislative and Executive Branches of the Government, the rule against advisory opinions implements the separation of powers prescribed by the Constitution and confines federal courts to the role assigned them by Article III. However, the rule against advisory opinions also recognizes that such suits often are not pressed before the Court with that clear concreteness provided when a question emerges precisely framed and necessary for decision from a clash of adversary argument exploring every aspect of a multifaced situation embracing conflicting and demanding interests. Consequently, the Article III prohibition against advisory opinions reflects the complementary constitutional considerations expressed by the justiciability doctrine: Federal judicial power is limited to those disputes which confine federal courts to a role consistent with a system of separated powers and which are traditionally thought to be capable of resolution through the judicial process.
Flast,
¶10 The mootness doctrine is closely related to these principles. Under that doctrine, the requisite personal interest that must exist at the commencement of the litigation (standing) must continue throughout its existence (mootness).

Havre Daily News, LLC v. City of Havre,
¶11 A court lacks jurisdiction to decide moot issues or to give advisory opinions insofar as an actual “case or controversy” does not exist.
See Greater Missoula,
¶ 23;
Seubert,
¶ 19;
Dennis v. Brown,
¶12 We conclude that the District’s Court’s initial instinct was correct. Once BCBS determined not to go through with the lease of HRAA land and was dismissed from the case, the dispute over the interpretation of §§ 67-11-211 and -232, MCA, and other statutes in the Airport Authorities Act became moot. As a result, the District Court no longer had before it a justiciable case or controversy; and it was required, therefore, to dismiss the action at that point.

¶ 22. In proceeding nevertheless to rule on the merits of the parties’ dispute, the court improperly rendered an advisory opinion-i.e., one advising what the law would be upon a hypothetical state of facts or upon an abstract proposition, not one resolving an actual “case or controversy.”
See Chovanak,
¶13 For the same reasons, we must dismiss this appeal. The parties essentially ask us to rule on the correctness of the District Court’s advisory opinion, relying as that court did on hypothetical facts and abstract propositions. This we may not do. As already noted, the request for an advisory opinion implicates the question of justiciability.
See Greater Missoula,
¶ 23. Accordingly, such a request presents a threshold question which this Court must raise and address sua sponte-even if, as here, it is not raised by the litigants.

Jumping Rainbow Ranch v. Conklin,
¶14 We conclude that our review of the District Court’s orders resolving the parties’ dispute over the interpretation of §§ 67-11-211 and -232, MCA, and other statutes in the Airport Authorities Act would result in yet another advisory opinion resolving a matter in which there is no longer an actual case or controversy, but rather an abstract difference of opinion regarding a moot question.
See Hardy,
¶15 While we appreciate the frustration over the language in the statutes as evidenced by the District Court in its decision and the parties in their arguments on appeal, those matters are better addressed to and clarified by the Legislature. Therefore,
¶16 IT IS ORDERED that this cause is dismissed as a nonjusticiable request for an advisory opinion from this Court.
¶17 IT IS FURTHER ORDERED that the District Court’s March 18, 2009 order and its May 13, 2009 order are vacated.
¶18 IT IS FURTHER ORDERED that this cause is remanded to the District Court for the entry of an order dismissing the action as nonjusticiable.
¶19 IT IS FURTHER ORDERED that the Clerk of this Court serve a copy of this Opinion and Order on all counsel of record, and on the Honorable Jeffrey M. Sherlock, District Court Judge, presiding over Cause No. BDV-2008-882.
DATED this 9th day of February, 2010.
