| Jn 2009, an amended judgment was entered reflecting that appellant Gary J. Mason had been found guilty of rape, sexual indecency with a child, and possessing matter depicting sexually explicit conduct involving a child for which he was sentenced to serve consecutive sentences of 300 months’ imprisonment for rape and 72 months’ imprisonment for sexual indecency with a child, with a concurrent sentence of 120 months’ imprisonment for possessing matter depicting sexually explicit conduct involving a child. The Arkansas Court of Appeals affirmed. Mason v. State, 2009 Ark. App. 598, 330 S.W.3d 445.
In 2013, appellant filed in the Jefferson County Circuit Court a pro se petition for declaratory judgment and for writ of mandamus against the Director of the Arkansas Department of Correction (“ADC”), in whose custody appellant is being held, concerning his eligibility for *681parole based on the sentence for rape. The circuit court dismissed the |2petition, and appellant brings this appeal from the order.1 We review the action of the circuit court de novo, and we will uphold the circuit court’s decision in a declaratory judgment and mandamus action unless it is clearly erroneous. Carroll v. Hobbs, 2014 Ark. 395, 442 S.W.3d 834 (per curiam).
Appellant’s eligibility for parole was determined by the law in effect at the time his offenses were committed between August 2007 and March 2008. See id. Under the provisions of Arkansas Code Annotated section 16-93-611(a)(1) (Repl. 2006) (repealed by Act 570 of 2011), as in effect at the time appellant committed the offenses, he was required to serve at least seventy percent of the 300-month sentence for rape before being eligible for parole or transfer. The seventy-percent requirement applies notwithstanding any law allowing the award of meritorious good time or any law to the contrary. See Gardner v. Hobbs, 2013 Ark. 439, 2013 WL 5878140 (per curiam).
Appellant argued in the petition that the application of section 16—93—611 (a)(1) to his sentence was an unconstitutional “sentence enhancement” illegally applied by the ADC without a court order, that he was denied due process of law by the application of the statute without notice, and that the ADC usurped the power of the judiciary by modifying his |ssentence.
The purpose of the declaratory-judgment statutory scheme is to settle and to afford relief from uncertainty and insecurity with respect to rights, statutes, and other legal relations. McCutchen v. City
of Ft. Smith, 2012 Ark. 452, 425 S.W.3d 671. This court has held that there are four requisite conditions before declaratory relief may be granted: (1) there must exist a justiciable controversy; (2) the controversy must be between persons whose interests are adverse; (3) the party seeking relief must have a legal interest in the controversy; (4) the issue involved in the controversy must be ripe for judicial determination. Ark. Dep’t of Human Servs. v. Ross-Lawhon, 290 Ark. 578, 721 S.W.2d 658 (1986). Here, appellant failed to state a basis for declaratory judgment under Arkansas Code Annotated sections 16-
111-101 to -111 (Repl. 2006). Without establishing a right to declaratory judgment, appellant provided no basis for a writ of mandamus to issue. Cridge v. Hobbs, 2014 Ark. 153, 2014 WL 1344404 (per curiam). The purpose of a writ of mandamus is to enforce an established right or to enforce the performance of a duty. Banks v. Hobbs, 2013 Ark. 377, 2013 WL 5519863 (per curiam). A writ of mandamus is issued by this court only to compel an official or a judge to take some action, and, when requesting a writ, a petitioner must show a clear and certain right to the relief sought and the absence of any other remedy. Id. A writ of mandamus will not lie to control or review matters of discretion. Id.; see also Aguilar v. Lester, 2011 Ark. 329, 2011 WL 3930362 (per curiam).
With respect to appellant’s argument that the appellee has denied him due process of law by applying the statute at issue to his case, there is no constitutional right or entitlement to parole that would *682invoke due-process protection. Cridge, 2014 Ark. 153; see also Michalek v. Lockhart, 292 Ark. 301, 730 S.W.2d 210 (1987).
As to appellant’s contention that a trial court order was required before the ADC could apply certain statutes to appellant’s parole-eligibility status, parole eligibility is not within the purview of the trial court. See Mitchem v. Hobbs, 2014 Ark. 233, 2014 WL 2019278 (per curiam) (citing Thompson v. State, 2009 Ark. 235 (per curiam)) (holding that, because determining parole eligibility is the prerogative of the ADC, the trial court would not have had authority to place conditions as to parole eligibility on the sentence pronounced).
The arguments raised by appellant in his petition and in this appeal stem primarily from his erroneous characterization of section 16-93-611 as an enhancement statute. Parole-eligibility determinations by the ADC do not constitute a modification of a prison sentence. Cridge, 2014 Ark. 153. The determination of parole eligibility is solely within the province of the ADC. Aguilar, 2011 Ark. 329. This court has repeatedly held that the ADC, not the sentencing court, determines parole eligibility. See Pitts v. Hobbs, 2013 Ark. 457, 2013 WL 5968940 (per curiam) (rejecting the argument that a parole-eligibility statute cannot be applied to a sentence absent some reference to the particular statute on the judgment- and-commitment order); Stephens v. Hobbs, 2012 Ark. 332, 2012 WL 4017376 (per curiam) (rejecting appellant’s due-process argument that a parole-eligibility statute should not apply when the jury, the court, and the appellant were unaware of the statute and did not intend for it to apply to the judgment); Johnson v. State, 2012 Ark. 212, 2012 WL 1739110 (per curiam) (holding that parole eligibility falls clearly within the domain of the executive branch and specifically the ADC, as fixed by statute); Thompson v. State, 2009 Ark. 235, 2009 WL 1784086 (per curiam) (holding that, because determining parole eligibility is the prerogative [ 5of the ADC, the trial court would not have had authority to place conditions of parole eligibility on the sentence announced); see also Abdullah v. Lockhart, 302 Ark. 506, 790 S.W.2d 440 (1990); Fain v. State, 286 Ark. 35, 688 S.W.2d 940 (1985).
Here, appellant was found guilty of rape committed between August 2007 and March 2008, and the ADC, in accordance with section 16-93-611, applied the statute to appellant’s sentence for that crime to determine his parole-eligibility date. Section 16-93-611, as in effect when appellant committed the offense, provided that any person who is found guilty of, or who pleads guilty or nolo contendere to, rape shall not be eligible for parole until the person serves seventy percent of the term of imprisonment to which the person is sentenced. We have specifically recognized that the statute does not allow for parole or transfer until a person who has been found guilty of, or who pleads guilty or nolo contendere to, designated crimes has served seventy percent of his sentence. Ritter v. Hobbs, 2014 Ark. 68, 2014 WL 585995 (per curiam); Anderson v. Hobbs, 2013 Ark. 354, 2013 WL 5434693 (per curiam).
Finally, to the extent that appellant contends that section 16-93-611 should not have been applied to his sentence by the ADC because the face of the judgment did not cite the statute, we rejected the same argument in Pitts, 2013 Ark. 457.
Inasmuch as none of the claims for relief raised in appellant’s petition demonstrated that he was entitled to any relief by means of a declaratory judgment or a writ of mandamus, the circuit court did not err in *683declining to grant the relief sought. The order is affirmed.
Affirmed.
