OPINION
Bob Pemberton, Justice
The issues presented in this appeal concern whether a claimant can bring suit under the Uniform Declaratory Judgments Act (UDJA)1 to establish a right to compensation under Texas’s wrongful-imprisonment statute.2 The district court concluded that such a suit was beyond its subject-matter jurisdiction to adjudicate. We agree and affirm.
BACKGROUND
Compensation for wrongful imprisonment in Texas
An initial overview of Texas law governing compensation for wrongful imprisonment aids understanding of the suit in question and, ultimately, the issues on appeal. It is well established that the common law—the starting or default legal rule—recognizes no right to recover against the government for wrongful or erroneous imprisonment,3 and sovereign [791]*791immunity—the age-old common-law doctrine that “generally shields our state government’s ‘improvident acts’ .., against the litigation and judicial remedies that would be available if the same acts were committed by private persons”4—would bar both jurisdiction and liability in any lawsuit purporting to seek that relief in court.5 Texas has departed somewhat from the strict common-law rule, however, beginning with a 1950s-era amendment to the Texas Constitution that authorized the Legislature, “under such regulations and limitations as the Legislature may deem expedient,” to “grant aid and compensation” to any person fined or imprisoned under the laws of this State “for any offense for which he or she is not guilty.”6 Because the amendment in itself did not grant a right or means of compensation, but merely authorized the Legislature to create one,7 any recovery for wrongful or erroneous convictions in Texas has depended upon statutes enacted pursuant to the constitutional grant and “such regulations and limitations as the Legislature has deemed expedient” within them. The most recent iteration of these statutes—and the only one presently existing—is found in Chapter 103 of the Civil Practice and Remedies Code,8 now commonly known as the Tim Cole Act.
In its current form, Chapter 103 in material part limits eligibility for compensation solely to a person who has “served in whole or in part a sentence in prison under the laws of this state” and also satisfies one of three alternative additional prerequisites that are prescribed in Paragraphs (A), (B), and (C) of Section -103.001(a)(2); (2) the person:
[792]*792(A) has received a full pardon on the basis of innocence for the crime for which the person was sentenced;
(B) has been granted relief in accordance with a writ of habeas corpus that is based on a court finding or determination that the person is actually innocent of the crime for which the person was sentenced; or
(C) has been granted relief in accordance with a writ of habeas corpus and:
(i) the state district court in which the charge against the person was pending has entered an order dismissing the charge; and
(ii) the district court’s dismissal order is based on a motion to dismiss in which the state’s attorney states that no credible evidence exists that inculpates the defendant and, either in the motion or in an affidavit, the state’s attorney states that the state’s attorney believes that the defendant is actually innocent of the crime for which the person was sentenced.9
Paragraphs (B) and (C) are of primary importance in this case, and we should initially note two of their features that will become relevant to the discussion. First, Paragraphs (B) and (C) each require that a claimant “has been granted relief in accordance with a writ of habeas corpus.”10 Second, Paragraphs (B) and (C) each incorporate an additional requirement that the claimant be deemed “actually innocent of the crime for which the person was sentenced.”11 Paragraph (B) requires that the “relief in accordance with a writ of habeas corpus” must be “based on a court finding or determination that the person is actually innocent of the crime for which the person was sentenced.”12 Paragraph (C), on the other hand, requires “relief in accordance with a writ of habeas corpus” plus dismissal of pending charges “based on a motion to dismiss in which the state’s attorney states that no credible evidence exists that inculpates the defendant and, either in the motion or in an affidavit, the state’s attorney states that the state’s attorney believes that the defendant is actually innocent of the crime for which the person was sentenced.”13
The Texas Supreme Court has held that “actually innocent” within Paragraph (B)— and which logically would also apply to the parallel usage in (C)—denotes either of the two “actual innocence” concepts that have evolved in criminal jurisprudence as a basis for obtaining relief through post-conviction habeas corpus 14—the “bare” or “Herrerar-type” actual-innocence theory founded on newly discovered evidence or the procedurally-focused “Schlup-type” theory15—such that a habeas petitioner [793]*793successful under either theory could qualify for compensation under Paragraph (B).16 This Court had previously reached a similar conclusion in State v. Young when construing a prior version of Section 103.001 that had not contained an explicit reference to habeas corpus, but based compensation eligibility on whether the claimant had been “granted relief on the basis of actual innocence for the crime for which the person was sentenced.”17 Considering. that “actual innocence” had acquired a specific meaning and significance in habeas-corpus jurisprudence, we reasoned that “ ‘has been granted relief based on actual innocence’ ” as used in the then-applicable version of Section 103.001 “connotes both a specific standard of proof and a procedural framework through which such relief is obtained—a [post-conviction] writ of habeas corpus on grounds of ‘actual innocence.’ ”18 Consequently, we held that a claimant who had obtained reversal of a criminal conviction on direct appeal had not been “granted relief based on actual innocence” and was not eligible for compensation.19
Chapter 103 also prescribes the procedural mechanism by which a claimant must seek any compensation for which he or she is mqde eligible under Section 103.001. Although the Legislature had previously authorized recovery under Chapter 103 through suit against the State,20 the sole means provided under the current version is administrative—the claimant must make application with the Comptroller21 by the third anniversary of the date either (as applicable to the basis for eligibility) the person received the pardon required under Paragraph (A) of Section 103.001(a)(2), the order of dismissal required by Paragraph (C) was signed, or “the person’s application for a writ of habeas corpus was granted as provided by [Paragraph (B)].”22 Chapter 103 further specifies that the claimant must submit a completed application form together with documentary support for the claim, which must include “a verified copy of the pardon, court order, motion to dismiss, and affidavit, as applicable,” on which the claimant relies to estab[794]*794lish eligibility for compensation.23 The Comptroller is then charged with determining the claimant’s eligibility from these verified documents, and “shall deny the claim” if the documents “do not clearly indicate on their face that the person is entitled to compensation under Section 103.001(a)(2).” 24 Chapter 103 additionally specifies that the Comptroller’s eligibility determinations are “ministerial,”25 denoting legislative intent to leave nothing to the Comptroller’s discretion.26
If the Comptroller determines that the claimant is eligible for compensation, the Comptroller is then to ascertain the amount of compensation owed by examining the documentation under standards prescribed elsewhere in the statute.27 If, on the other hand, the Comptroller denies the claim, the Comptroller must “state the reason for the denial” and provide the claimant thirty days in which to submit an application “to cure any problem identified.” 28 In the event the claimant submits a second or revised application in an attempt to cure the defect, the Comptroller must again determine the claimant’s eligibility and (if found eligible) the amount owed.29
In the event the Comptroller denies this second or revised claim, the Legislature has provided for judicial review to the extent “the claimant may bring an application for mandamus relief.”30 Although not specified explicitly in Chapter 103 itself, this mandamus proceeding must be filed in the Texas Supreme Court, as only that court has jurisdiction to issue the writ against the Comptroller.31
Springsteen’s efforts to obtain compensation
The claimant here, Robert Bums Springsteen, IV, was imprisoned for several years—some spent on death row—after being convicted in Travis County of capital murder and sentenced to death on evidence implicating him in Austin’s notorious “Yogurt Shop Murders.” Springsteen’s trial had predated the U.S. Supreme Court’s seminal Crawford decision concerning “testimonial” hearsay and the Confrontation Clause,32 and in 2006 the Court of Crimi[795]*795nal Appeals reversed his conviction based on the State’s use of a co-defendant’s statement in a manner proving to be inconsistent with Crawford.33 But the court overruled a challenge by Springsteen to the legal sufficiency of the evidence supporting his conviction (thus permitting retrial) and to the voluntariness and admissibility of a purported confession he himself had made.34
In 2008, as Springsteen remained incarcerated awaiting retrial, DNA testing of crime-scene evidence through techniques not previously available revealed the DNA of an unknown male and not that of Springsteen or others previously charged. Ensuing investigation by the State failed to ascertain the unknown person’s identity or involvement in the crimes. Eventually, as a July 2009 trial setting approached, the State, though professing its continuing belief that Springsteen had been involved in the Yogurt Shop Murders, obtained a continuance in light of the “risk” of proceeding to trial against Springsteen on the then-existing state of the evidence. The trial court granted the continuance but released Springsteen on bond, reset trial for late October, and ordered that no further continuances would be granted based on the State’s need to investigate the DNA evidence. With continued investigation remaining unfruitful as the October trial date approached, the State, terming the action its “only viable option,” moved for and obtained dismissal of all charges against Springsteen.
With the previous criminal charges against him thus resolved—though the potential for future prosecution presently remains, at least legally35—Springsteen has sought remedy for his “wrongful imprisonment” and “damaged reputation” through compensation under Chapter 103. His foundational premise is that the events in his criminal proceedings, particularly the revelation of the new DNA evidence, establish or could be shown to establish his “actual innocence,” in a bare-innocence sense, of the Yogurt Shop Murders. This, Springsteen reasons, “functionally” satisfies or would satisfy Paragraph (B)’s requirement of “a court finding or determination that the person is actually innocent of the crime for which the person was sentenced,” and he similarly posits that the State’s motion to dismiss his charges “effectively” amounted to the State’s concessions of “actual innocence” and lack of evidence as required by Paragraph (C).36 [796]*796As for the additional requirement of “relief in accordance with a writ of habeas corpus” common to both Paragraphs (B) and (C),37 Springsteen acknowledges that he obtained relief from his conviction through direct appeal, not habeas corpus, a fact that our Young decision deemed fatal to a compensation claim made under the prior version of Chapter 103.38 But Springsteen perceives the current statute to be broader and distinguishable from the version we addressed in Young because it requires “relief in accordance with a writ of habeas corpus,” phrasing he views as leaving room for relief that can be said to have the same effect as relief through post-conviction ha-beas corpus.39 From this premise, Springsteen reasons that “[t]he relief provided by a Court of Criminal Appeals’s reversal of conviction is ... in accordance with a writ of habeas corpus” because “[b]oth accomplish the same goal—releasing from prison a person who constitutionally should not be there.”
Springsteen initially sought Chapter 103 compensation by making application with the Comptroller.40 The Comptroller denied the claim, concluding that Springsteen had failed to present documentation reflecting any of Section 103.001(a)(2)’s three alternative bases for compensation eligibility.41 Springsteen then filed a second or revised claim with the Comptroller, which was also denied.42
In response to the Comptroller’s rulings, Springsteen has not pursued any attempt to obtain the mandamus relief from the Texas Supreme Court that Chapter 103 authorizes.43 He has turned to other courts instead, beginning with the United States District Court for the Western District of Texas. In that forum, Springsteen sued the Comptroller seeking a declaratory judgment that he is “actually innocent” of the Yogurt Shop Murders as a means of establishing entitlement to compensation under Paragraph (B), coupled with a claim for mandamus relief to compel the Comptroller to make payment in the event she denied his claim post-declaration.44 The district court dismissed the claims for want of jurisdiction, citing Eleventh Amendment immunity and lack of standing.45 In regard to standing, the court reasoned that the sought-after declaration would ultimately fail to redress the harm complained of— “being denied compensation under Chapter 103”—because entitlement to compensation under Chapter 103 “is a question first for the Texas Comptroller, and then for the Texas Supreme Court,” and that Paragraph B in any event required an [797]*797actual-innocence finding made “in the context of a habéas corpus proceeding.”46
Following the dismissal of Springsteen’s federal suit, Springsteen filed—in Bexar County state district court—the suit giving rise to this appeal. Similar to his federal action, Springsteen’s present suit seeks to establish a right to compensation under Chapter 103 through three alternative forms of declaratory relief under the UDJA. First, Springsteen prays that the court “clarify and declare his rights and status under TCPRC 103.001, issuing a declaratory judgment that he is entitled to the relief for which he qualifies under the statute.” “Alternatively, should the Court find that Petitioner does not already fit within the parameters of 103.001,” Springsteen prays that “he be given a forum within this court to litigate that issue, pursuant to his 14th Amendment right to due process, and ... prove to [the trial court] that he does indeed fit within the class for whom the Tim Cole Act was enacted by the Legislature.” As illuminated by subsequent briefing and argument, the former claim seeks application of Paragraphs (B) and (C) to the already-existing factual or evidentiary record, while the latter claim contemplates additional development of an underlying “actual innocence” ground as a means of establishing eligibility for compensation under (B). Springsteen’s third claim seeks the relief requested by the second claim, but in an “alternative forum,” if needed.
Springsteen purported to style his declaratory-judgment suit as an “ex parte” proceeding that did not seek relief against any particular defendant or adverse party. However, the prosecutor having jurisdiction over any criminal proceedings arising from the Yogurt Shop Murders—Travis County District Attorney Rosemary Lehmberg, in her official capacity (Lehm-berg)—made filings in opposition to Springsteen’s claims. Springsteen ultimately conceded Lehmberg’s “standing” as an “interested party” whom the UDJA would require to be joined in the action47 and served her with process, though he endeavored to distinguish her status of “interested party” from that of a “defendant” in an apparent attempt to avoid implicating sovereign immunity.48 The “interested party” Lehmberg moved to transfer venue to Travis County (ultimately successfully), answered, and asserted a plea to the jurisdiction. In her plea, Lehmberg asserted that the suit was barred by sovereign immunity; that it failed to present any justiciable controversy for reasons that included, but were not limited to, the standing defects identified in Springsteen’s federal action; that it improperly sought a declaration of rights regarding criminal liability; and that it failed to allege a viable constitutional claim,
[798]*798Following a hearing at which only argument was presented, the Travis County district court granted Lehmberg’s plea without specifying grounds and dismissed Springsteen’s suit with prejudice. This appeal ensued.
ANALYSIS
Springsteen urges that the district court erred in concluding that it lacked subject-matter jurisdiction over his claims. Although he structures his arguments as five issues corresponding to the jurisdictional challenges Lehmberg raised in her plea,49 we can focus our analysis on a narrower set of legal principles that are ultimately dispositive.50
A central theme of Springsteen’s arguments on appeal is that his claims are justiciable, are not barred by sovereign immunity, and should otherwise survive to the merits- because they seek “statutory construction” of Chapter 103 and declarations relating to his “rights” or “status” under it.51 He further maintains that the UDJA confers jurisdiction on the district court to entertain these claims and that sovereign immunity would be no bar even apart from the significance he ascribes to the suit’s “ex parte” characterization. But the UDJA is not so powerful a weapon in establishing jurisdiction.
It is true that the UDJA generally authorizes claimants “whose rights, status, or other legal relations are affected by a statute” to “have determined any question of construction or validity arising under the . statute ... and obtain a declaration of rights, status, or other legal [799]*799relations thereunder.”52 But this authorization is not a grant of jurisdiction to entertain such a claim—as the Texas Supreme Court has instructed us, the UDJA generally “does not enlarge the trial court’s jurisdiction but is ‘merely a procedural device for deciding cases already within a court’s jurisdiction.’ ”53 Nor, similarly, can “a litigant’s couching its requested relief in terms of declaratory relief ... alter the underlying nature of the suit.”54 And as the high court has clarified in recent years, the UDJA’s sole feature that can impact trial-court jurisdiction to entertain a substantive claim is the statute’s implied limited waiver of sovereign or governmental immunity that permits claims challenging the validity of ordinances or statutes.55 It has squarely repudiated the once-widespread notion that the UDJA confers some broader right to sue government to obtain “statutory construction” or a “declaration of rights.”56
Springsteen has not asserted and indeed disclaims any challenge to the validity of Chapter 103 (and understandably so, as he seeks compensation made available under that statute). Consequently, the UDJA in itself ultimately has no bearing on whether Springsteen’s claims invoke the district court’s jurisdiction. We must look instead to the claims’ underlying substantive nature in order to determine whether the district court had jurisdiction to entertain them.57 Doing so reveals essentially the same jurisdictional defects the federal court identified in holding that Springsteen lacked standing to prosecute his earlier claims there.
By suing for declarations that he is entitled to compensation under Chapter 103 or satisfies particular eligibility requirements under Paragraphs (B) or (C), Springsteen seeks determinations that Texas law has vested in the Comptroller, subject to review by the Texas Supreme Court.58 The right to compensation under Chapter 103 is purely a creature of statute—no right or entitlement to compensation for wrongful imprisonment would ex[800]*800ist otherwise, as previously explained.59 That statutory creation, further, was enacted pursuant to a constitutional authorization that also explicitly permits the Legislature to impose “such regulations and limitations” on the compensation right “as the Legislature may deem expedient.”60 The Legislature has seen fit not only to prescribe specific eligibility requirements and other substantive limitations on this statutorily-created compensation right, but also a specific procedural mechanism for obtaining that remedy—application to the Comptroller, with judicial review solely by mandamus to the Texas Supreme Court. This statutory structure, as the Texas Supreme Court has confirmed recently, embodies the vesting of exclusive jurisdiction in the Comptroller to make the initial determinations with which Chapter 103 charges him.61 And where, as here, the Legislature has vested exclusive jurisdiction in an agency to make the initial determination in a dispute, it displaces any jurisdiction that the district court might otherwise possess over that subject matter.62
Likewise, any attempt by Springsteen to challenge the Comptroller’s determinations through his suit would infringe upon the exclusive jurisdiction of the Texas Supreme Court.63 To the extent Springsteen’s references to “Due Process” attempt to invoke some broader scope or means of judicial review,64 the asserted “property right” on which he predicates his arguments amounts merely to whatever compensation the Comptroller, subject to Texas Supreme Court review, determines he is [801]*801owed under Chapter 103.65 Consequently, Springsteen has not pleaded any viable Due Process-based claim.66 Similarly, while Springsteen also refers to the Open Courts provision of the Texas Constitution,67 that protection extends only to a “well-established common-law cause of action,” 68 and none is implicated here.69
Springsteen fares no better in attempting to .invoke the district court’s jurisdiction for purposes of litigating, through the UDJA, an underlying “actual innocence” claim in order to establish eligibility for compensation under Paragraph (B). Contrary to Springsteen’s reasoning, his sought-after declaration of “actual innocence,” were he to succeed in obtaining it, would have no bearing on his asserted eligibility for compensation under Paragraph (B). We need go no farther than to observe that Paragraph (B) requires that Springsteen “has been granted relief in accordance with a writ of habeas corpus that is based on a court finding or determination that the person is actually innocent of the crime for which the person was sentenced.”70 The Legislature’s use of “based on” denotes that the “court finding or determination” of actual innocence must be a foundational or fundamental part of the “relief.”71 Accordingly, even accepting Springsteen’s premise that the reversal of his conviction on direct appeal can be considered “relief in accordance with habeas corpus,”72 the actual-innocence declaration he seeks would lack the required temporal and substantive nexus to that reversal. The declaration would thereby amount merely to an abstract proposition of law having no impact on Springsteen’s asserted eligibility for compensation under Para[802]*802graph (B)—the distinguishing characteristic of an advisory opinion.73 The district court lacked subject-matter jurisdiction to entertain the claim.74
Springsteen has not demonstrated any alternative , jurisdictional basis for his claims. He has couched his claims entirely as a means of establishing a right to compensation under Chapter 103, further disclaiming any intent to litigate actual innocence as might bear upon any potential future criminal prosecution. And to the extent Springsteen’s claims would seek to affect his status as against the criminal law, multiple additional jurisdictional barriers would come into play, including jurisdictional prohibitions against civil courts issuing UDJA declarations of rights and status under the criminal law,75 and sovereign immunity. Sovereign immunity could not be avoided merely through Springsteen’s insistence on styling his suit as an “ex parte” proceeding, as the substantive effect of any claim seeking to determine his status under the criminal law would operate against the State of Texas, in whose name and by whose authority the criminal law is enforced.76
We must credit Springsteen’s counsel with diligence and creativity in their attempts to overcome governing law that is, bottom line, highly unfavorable to a claimant in their client’s situation. But we are bound to follow that governing law, and it dictates the same basic conclusion as in Young—the district court lacks subject-matter jurisdiction to adjudicate Springsteen’s claims. It is similarly beyond judicial jurisdiction to decide whether that governing law should provide different or more generous remedies to the formerly imprisoned than it does—such decisions, as we also recognized in Young, are the province of the Legislature.77
[803]*803CONCLUSION
We affirm the district court’s judgment dismissing Springsteen’s claims for want of subject-matter jurisdiction.
