Panel consists of Justices TAFT, KEYES, and ALCALA.

OPINION
EVELYN V. KEYES, Justice.
Appellant, Bartholomew U. Stephens, challenges the trial court's order that granted a plea to the jurisdiction in favor of appellees, the City of Houston, Mayor Bill White, Toni Lawrence, Carol Galloway, Mark Goldberg, Ada Edwards, Addie Wiseman, M.J. Khan, Pam Holm, Carol Alvarado, Gordon Quan, Shelley Sekula-Gibbs, Ronald Green and the City of Houston Civil Service Commission for Municipal Employees (collectively referred to as "the City"). In four issues on appeal, Stephens argues that (1) the City Council and government of the City of Houston ignored the limitations and delegations in the Charter of the City of Houston; (2) the City of Houston ignored a rejection of a Charter change by the voters by adopting an ordinance that contradicts the existing Charter language; (3) a department head in the Houston City government improperly terminated a city employee because authority to terminate rests exclusively with the City's Mayor; and (4) Texas courts may properly review the termination of an *165 employee of a municipality governed by a City Charter.
The City responds that the district court properly granted its plea to the jurisdiction because there was no live controversy between the parties when Stephens sued, Stephens lacked standing to bring this action under the Declaratory Judgment Act, and therefore, the court lacked subject matter jurisdiction over this suit.
We affirm.

Background
Stephens had been employed by the City of Houston since 1989. In March 2005, Stephen Williams, the Director of the City's Health and Human Services Department, notified the Civil Service Commission for Municipal Employees of the City of Houston ("CSC") that he had indefinitely suspended Stephens pursuant to article V-a, section 3 of the Houston City Charter and Houston City Code § 14-182(b).[1] Stephens was also notified that he was indefinitely suspended and that he could appeal the decision. Stephens appealed Williams's decision to the CSC. After reviewing documentation and hearing testimony, the CSC "upheld and sustained" Stephens's indefinite suspension in April 2005, resulting in his permanent dismissal from City employment under article V-a, section 3 of the City Charter. Stephens did not appeal the CSC's final decision terminating his employment with the City.
On July 18, 2006, nearly a year after the CSC upheld his termination, Stephens filed an original petition seeking a declaration that the City had unlawfully amended a separate article of its charter  article VI, section 7a  two months before he was indefinitely suspended in March 2005 by amending the Houston Code of Ordinances (Houston Code section 14-182(b)) to permit the City's department directors to suspend civil service employees indefinitely.[2] He sought a further declaration that his dismissal was beyond the power of the department head and, therefore, wrongful, *166 and he sought reinstatement to his prior position and back pay.
In his petition, Stephens contended that before January 25, 2005, the effective date of section 14-182(b) of the City Code, the "mayor had the exclusive authority and power to indefinitely suspend any civil service employee, as granted to [the mayor] by Article VI, section 7a of the Houston City Charter." Stephens argued that "[t]o give department head[s] and director[s] this type of authority, the Charter must be amended by the voters of the City of Houston pursuant to Article XI, Section 5 of the Texas Constitution."[3] Stephens also argued that the CSC had "acted outside its authority in upholding the decision by a director to indefinitely suspend [Stephens] and other civil service employees similarly situat[ed]." In his request for relief, Stephens asked that "Houston Code § 14-182(b) be declared unconstitutional, unlawful, or invalid in violation of Article XI, Section 5 of the Texas Constitution" and "that he be reinstated to the position of Environmental Investigator III and awarded back pay from the date of his indefinite suspension until the date of reinstatement."
The City responded to Stephens's filing of this cause of action by a plea to the jurisdiction contending (1) that Stephens's claims were moot because his suspension was final and there was no timely appeal from that suspension on constitutional grounds and (2) that as a non-employee of the City, he lacked standing either to bring a declaratory judgment action complaining about the provisions under which he was terminated or to seek reinstatement and back pay. The City also argued that it made no difference who had suspended Stephens because the CSC heard Stephens's appeal and upheld the order.
At the hearing on the City's plea to the jurisdiction, the City argued that Stephens lacked standing because there was no justiciable controversy that the court could resolve. The City reasoned that there was no appeal from the CSC ruling and that Stephens did not dispute that the decision of the CSC was final. The City also argued that, in the absence of a live controversy that could affect his rights, Stephens lacked standing to bring an original action for a judgment declaring the statute under which he was terminated invalid and seeking damages and reinstatement under the Declaratory Judgment Act.
After the hearing, Stephens was permitted to file a response to the plea to the jurisdiction. He argued that the CSC's April 2005 order terminating his employment was not final as to the validity of the amended ordinance. He also argued that the "mayor has express[ ] power to remove all employees subject to review by the Civil Service Commission." He acknowledged that a department head has the power to suspend a Civil Service employee, but he disputed that a department head has charter authority to "indefinitely suspend," or to "remove," a civil service employee.[4] The trial court granted the City's plea to the jurisdiction and dismissed the case.

Plea to the Jurisdiction

Standard of Review
"A plea to the jurisdiction is a dilatory plea, the purpose of which is to *167 defeat a cause of action without regard to whether the claims asserted have merit." Bland Indep. Sch. Dist. v. Blue, 34 S.W.3d 547, 554 (Tex.2000). Although the plaintiff's claims may form the context against which the jurisdictional plea is determined, the plea generally "should be decided without delving into the merits of the case." Id. "[A] court deciding a plea to the jurisdiction is not required to look solely to the [plaintiff's] pleadings but may consider evidence and must do so when necessary to resolve the jurisdictional issues raised." Id. at 555. However, in general, "the proper function of a dilatory plea does not authorize an inquiry so far into the substance of the claims presented that plaintiffs are required to put on their case simply to establish jurisdiction." Id. at 554. We review de novo a trial court's ruling on a jurisdictional plea, construing the pleadings in the plaintiff's favor and looking to the pleader's intent. See Tex. Natural Res. Conservation Comm'n v. IT-Davy, 74 S.W.3d 849, 855 (Tex.2002); Tex. Ass'n of Bus. v. Tex. Air Control Bd., 852 S.W.2d 440, 446 (Tex.1993). In addition, courts always have jurisdiction to determine their own jurisdiction. Houston Municipal Employees Pension Sys. v. Ferrell, 248 S.W.3d 151, 158 (Tex.2007).

Stephens's Standing to Bring This Declaratory Judgment Action
Stephens filed this declaratory judgment action more than a year after his permanent dismissal from City employment. He argues that he has standing to bring this action "because the decision rendered by the Civil Service Commission did not dispose of his claim that Defendant, the mayor, and city council exceeded powers of the charter in permitting his department head to terminate him." Stephens also maintains that he is a taxpayer and a registered voter of the City. The City argues that Stephens lacks standing because there is no longer a controversy between the parties and his claims are therefore moot. The City also argues that the trial court lacked jurisdiction over the declaratory judgment action because immunity from suit bars declaratory judgment actions that seek to establish the basis for monetary damages.
Standing is implicit in the concept of subject matter jurisdiction. Tex. Ass'n of Bus., 852 S.W.2d at 443. Subject matter jurisdiction is essential to the authority of a court to decide a case. Id. In analyzing issues of standing, we focus on whether a party has a sufficient relationship with the lawsuit to have a "justiciable interest" in the outcome. Austin Nursing Ctr., Inc. v. Lovato, 171 S.W.3d 845, 848 (Tex.2005). When a plaintiff is personally aggrieved, he has standing. Id.
The standing doctrine requires that there be a "real controversy between the parties" which "will be actually determined by the judicial declaration sought." Id. at 849 (quoting Nootsie, Ltd. v. Williamson County Appraisal Dist., 925 S.W.2d 659, 662 (Tex.1996)). Standing to challenge the constitutionality of a statute requires that the plaintiff have suffered some actual or threatened injury under the statute that unconstitutionally restricts his own rights. Barshop v. Medina County Underground Water Conservation Dist., 925 S.W.2d 618, 626 (Tex.1996). "If a case becomes moot, the parties lose standing to maintain their claims." Williams v. Lara, 52 S.W.3d 171, 184 (Tex.2001) (citing City of Los Angeles v. Lyons, 461 U.S. 95, 105-06, 103 S.Ct. 1660, 1666-67, 75 L.Ed.2d 675 (1983) (holding that inmates who had been released from jail lacked cognizable interest in obtaining injunctive or declaratory relief)). A litigant's request for relief under the Declaratory Judgment Act neither confers jurisdiction on a court nor changes *168 a suit's underlying nature, nor does it waive sovereign immunity to suits that seek to establish a basis for obtaining monetary damages. See IT-Davy, 74 S.W.3d at 855, 856; see also Ferrell, 248 S.W.3d at 159 (holding that trial court lacks jurisdiction when legislature has not authorized trial court to grant relief sought).
In this case, Stephens agrees that the CSC reviewed and upheld his indefinite suspension, resulting in the termination of his employment with the City, and that the CSC's order was final. The only question, therefore, is whether the CSC's final order was appealable.
Article V-a, section 3 of the City Charter is entitled "Removal of Employees." Last amended in 1982, section 3 authorizes a department head to suspend a City employee indefinitely, at which point "his salary shall cease."[5] HOUSTON, TEX., CITY CHARTER, art. V-a, § 3. The department head's order of suspension must be filed with the CSC, which may review the order if the employee files an appeal of the decision within ten days. Id. Section 3 further provides that the suspended employee "may, if he desires, file an appeal with the civil service commission which shall hold a hearing and render a decision in writing within thirty days after it receives the appeal as to whether the employee shall be permanently dismissed from the service of the city, or reinstated in his employment." Id. The Charter does not provide a right of appeal from the CSC's final order of dismissal or reinstatement.
It is well-established that there is no right to judicial review of an administrative order without an authorizing statute unless the order violates the constitutional rights of the plaintiff. Ferrell, 248 S.W.3d at 158; General Servs. Comm'n v. Little-Tex Insulation Co., 39 S.W.3d 591, 597 (Tex.2001). Specifically, in the absence of statutory authority, a municipal city employee has no inherent right to appeal an order of the CSC to the district court, "unless the commission's order affects vested property rights or otherwise violates some constitutional provision." See Harris v. Civil Service Comm'n for Municipal Employees of the City of Houston, 803 S.W.2d 729, 730 (Tex.App.-Houston [14th Dist.] 1990, no writ) (holding that "suspension was final following the decision of the hearing board, and [employee] had no right to appeal absent clear statutory authorization or a claim that his constitutional rights had been violated"); Smith v. City of Houston, 552 S.W.2d 945, 947 (Tex.Civ.App.-Houston [1st Dist.] 1977, no writ). Otherwise, the words "final and binding" when used to describe an administrative decision, preclude judicial review of the decision. Ferrell, 248 S.W.3d at 158.
After Williams indefinitely suspended Stephens, Stephens appealed to the CSC. The CSC conducted a hearing in which it considered testimony and evidence and upheld the indefinite suspension. The CSC's disposition resulted in Stephens's permanent dismissal from City employment under article V-a, section 3 of the City Charter. Stephens did not challenge that decision on the grounds that the CSC's order affected his "vested property rights or otherwise violated some constitutional provision." See Smith, 552 S.W.2d at 947. Likewise, there was no challenge that City Code section 14-182(b) illegally amended article V-A, section 3 of the City Charter, under which Stephens was terminated, and thus affected his constitutional rights.
*169 We conclude that the CSC issued a final order of dismissal which Stephens had no right to appeal and that he did not timely raise a constitutional challenge to that order. Thus, there is no live controversy affecting Stephens's constitutional rights. Because Stephens was permanently dismissed as a City employee and he failed to appeal the final dismissal order of the CSC on constitutional grounds, his claims are now moot and he lacks a legally cognizable interest in obtaining the declaratory relief he seeks. See Williams, 52 S.W.3d at 184. Moreover, the legislature has not conferred on the district courts the right to review a municipal employee's termination and to order reinstatement and back pay. See Ferrell, 248 S.W.3d at 159. Nor does the Declaratory Judgment Act confer jurisdiction on the courts to adjudicate claims seeking to establish the basis for monetary relief. See IT-Davy, 74 S.W.3d at 855, 856. We hold that the district court lacked subject matter jurisdiction over Stephens's declaratory judgment action and, therefore, the court did not err in granting the City's plea to the jurisdiction.

Conclusion
We dismiss the appeal for want of jurisdiction. We deny all outstanding motions as moot.[6]
