In this Consolidated appeal, plaintiff challenges the trial court’s dismissal of a writ of habeas corpus, its denial of his petition for alternative writ of mandamus, and its imposition of a filing fee in the latter proceeding. For the reasons explained below, we conclude that the trial court erred in dismissing the writ of habeas corpus and, accordingly, reverse the judgment in that case. Based on the trial court’s erroneous imposition of a filing fee, we also vacate the judgment in the mandamus proceeding.
The relevant historical facts are not in dispute. Plaintiff was convicted of aggravated murder, ORS 163.095(2) (1983), for a crime he committed in May 1984. He was sentenced to life in prison with a minimum of 20 years without possibility of parole. ORS 163.105(2) (1983). In December 1999, he requested that the Board of Parole and Post-Prison Supervision (board) hold a hearing for the purpose of determining whether he was “likely to be rehabilitated within a reasonable period of time.” ORS 163.105(3) (1983). On February 15, 2000, after hearing evidence, the board determined that plaintiff met that standard and converted the terms of his confinement to life imprisonment with the possibility of parole. ORS 163.105(4) (1983). The board set a projected parole release date of May 18, 2004, and scheduled an exit interview for November 2003.
In November 2000, plaintiff sought a writ of habeas corpus, asserting that, consistently with Norris v. Board of Parole, 331 Or 194, 13 P3d 104 (2000), cert den, 534 US 1028 (2001), he was entitled to be released on parole as of February 15, 2000, the date on which the board found him capable of rehabilitation. The trial court issued the writ, the state filed a return, and plaintiff filed a replication.1 The state then moved to dismiss the writ. In September 2001, the *333trial court granted the motion on the ground that habeas corpus relief was not the appropriate remedy, and entered judgment dismissing the writ. In November 2001, plaintiff petitioned for an alternative writ of mandamus, again asserting that he was entitled to release on parole as of February 15, 2000; the trial court denied the petition.
Plaintiff now appeals the judgments in both proceedings. Meanwhile, while the appeal were pending, the board postponed plaintiffs parole release date from May 18, 2004, to May 18, 2006.
In his first assignment of error, plaintiff argues that the trial court erred in dismissing the writ of habeas corpus because, the board having found that he is capable of rehabilitation, he was entitled under Norris to immediate parole release as of the date of that finding. According to plaintiff, Norris stands for the proposition that, when the board makes such a finding under relevant versions of ORS 163.105(3), it lacks discretion to “sustain” the 20-year minimum term of confinement provided in ORS 163.105(2) or to apply the parole “matrix” to the person — that is, to establish a fixture parole release date for the person based on the person’s offense severity, criminal history, and other applicable aggravating and mitigating factors. Rather, plaintiff maintains, the board must immediately release the person on parole in connection with the relevant sentence.2 Plaintiff also argues that, if interpreted otherwise, ORS 163.105 (1983) violates the Reformation Clause of Article I, section 15, of the Oregon Constitution; the Due Process Clause of the Fourteenth Amendment to the United States Constitution; and the proscriptions against cruel and unusual punishment in Article I, sections 13 and 16, of the Oregon Constitution and the Eighth Amendment to the United States Constitution. Finally, plaintiff argues that the trial court erred in concluding that habeas corpus relief is not the proper remedy for the board’s asserted errors because he lacks any other timely *334remedy such as judicial review under ORS 144.335 or mandamus.
In response, the state first concedes that the trial court erred in concluding that habeas corpus relief was not the proper remedy for plaintiff’s claimed deprivation. It argues, however, that the trial court properly dismissed the writ because, as a matter of statutory construction, the board’s finding that plaintiff was capable of rehabilitation under ORS 163.105(3) and (4) (1983) means only that plaintiff became eligible for future parole release, not that he is exempt from service of the 20-year minimum term provided in ORS 163.105(2) (1983) or from the board’s standards and procedures pertaining generally to parole release — including a psychological or psychiatric evaluation and, if warranted, the postponement of his parole release date — as provided in ORS 144.125. The state notes that to interpret ORS 163.105 as obviating those generally applicable standards and procedures for parole release would mean that persons convicted of aggravated murder are subject to fewer constraints regarding such release than persons convicted of less serious crimes.
The state acknowledges that its proposed construction is at odds with what the court ordered in Norris. The state nevertheless argues that the opinion cannot really mean what it says. According to the state, the “primary issue” in that case was whether the relevant versions of ORS 163.105(3) and (4) required the board not only to find whether an offender is capable of rehabilitation, but also separately to find that the terms of the offender’s confinement should be converted to life imprisonment with the possibility of parole. The Supreme Court properly determined, as the state suggests, that the statute requires only a single finding and that the “conversion” of the offender’s sentence to one of life with possibility of parole necessarily follows from the finding that the offender is capable of rehabilitation. The state posits, however, that the court erred in apparently concluding that such a finding also results in an offender’s automatic release on parole as of the date of the finding. According to the state, that question was not at issue in Norris; nor did the court provide any statutory construction analysis or other explanation supporting its conclusion in that regard. *335The state therefore urges us to reject plaintiffs argument in this case notwithstanding the aspect of Norris that supports it.
A motion to dismiss a writ of habeas corpus is treated as the functional equivalent of a summary judgment motion. Fort v. Palmateer, 169 Or App 568, 570, 10 P3d 291 (2000) (citing McClintock v. Schiedler, 123 Or App 334, 336 n 2, 859 P2d 580 (1993)). We review the record in the light most favorable to the nonmoving party to determine whether there are any genuine issues of material fact and whether the moving party is entitled to judgment as a matter of law. Fort, 169 Or App at 570 (citing Jones v. General Motors Corp., 325 Or 404, 420, 939 P2d 608 (1997), and Bedell v. Schiedler, 307 Or 562, 564, 770 P2d 909 (1989)). Here, as we have noted, the parties do not dispute any material facts. Accordingly, whether plaintiff is entitled to relief is solely a question of law, namely, the proper interpretation and application of ORS 163.105 (1983).
ORS 163.105 (1983) provided, in part:
“(2) When a defendant is convicted of murder defined as aggravated murder pursuant to ORS 163.095(2), the court shall order that the defendant shall be confined for a minimum of 20 years without possibility of parole, release on work release or any form of temporary leave or employment at a forest or work camp.
“(3) * * * [A]t any time after 15 years from the date of imposition of a minimum period of confinement pursuant to subsection (2) of this section, the State Board of Parole, upon the petition of a prisoner so confined, shall hold a hearing to determine if the prisoner is likely to be rehabilitated within a reasonable period of time. The sole issue shall be whether or not the prisoner is likely to be rehabilitated within a reasonable period of time. * * *
"*****
“(4) If, upon hearing all the evidence, the board finds that the prisoner is capable of rehabilitation and that the terms of the prisoner’s confinement should be changed to life imprisonment with the possibility of parole, or work release, it shall enter an order to that effect and the order shall convert the terms of the prisoner’s confinement to life *336imprisonment with the possibility of parole or work release. Otherwise, the board shall deny the relief sought in the petition.”
At issue in this case is whether, once the board made the finding under subsection (3) that plaintiff is capable of rehabilitation, it was required to release him on parole in connection with the relevant sentence.
The Supreme Court spoke to that question in Norris. In that case, the offender was convicted of two counts of aggravated murder and was sentenced under ORS 163.105 (1977)3 to two consecutive terms of life with minimums of 20 years without possibility of parole. Norris, 331 Or at 196. After 15 years, he petitioned for and received a hearing, at which the board found that he was capable of rehabilitation but declined to set a parole release date. Id. at 197. On reconsideration, the board “sustained” the offender’s consecutive 20-year minimums and set a parole release date reflecting the combined 40-year minimum terms. We reversed and remanded. Norris v. Board of Parole, 152 Or App 57, 952 P2d 1037 (1998).
In his brief on review in the Supreme Court, the offender argued that, after the board found him capable of rehabilitation, it was required under ORS 163.105 (1977) to convert his prison term to one of life with possibility of parole and to treat him as a “parolable” offender; that is, it was required to apply the “parole matrix” to his offenses and to set a parole release date without regard to the statutory minimum terms.
In turn, the state framed the issue as whether ORS 163.105 (1977) required the board separately to find both that an offender was capable of rehabilitation and that the offender’s sentence should be converted to life with possibility of parole; it argued that the statute required those separate findings and that, in that case, the board had not yet made the second finding. The state also posited that an effect of the latter determination — whether or not it was separately made — was that it permitted the board to set a parole release *337date through the application of relevant and generally applicable parole release criteria, which, according to the state, constituted yet another separate proceeding. The state also alluded to the possibility that the setting of a parole release date according to those criteria could “nullify” the 20-year statutory minimum.
In its opinion, the Supreme Court initially framed the issue as whether, under ORS 163.105 (1977), the board “had the authority to sustain [the offender’s] minimum terms of confinement after an affirmative finding that [the offender] was likely to be rehabilitated within a reasonable period of time.” Norris, 331 Or at 196. The court then described the parties’ arguments as follows:
“Petitioner argues that the only issue at a rehabilitation hearing under ORS 163.105(4) (1977) is whether the prisoner is capable of rehabilitation. He contends that the statutory phrase ‘and that the terms of * * * confinement should be changed’ does not refer to a separate finding, but merely describes the relief to be given when the Board makes such a finding. Petitioner further argues that, in light of the Board’s finding that he is capable of rehabilitation, the Board must convert the terms of his confinement to a parolable life sentence and set terms according to the matrix.
“As noted, the Board, for its part, argues that, under ORS 163.105(4) (1977), it must make two independent and co-equal findings before it may change the terms of a prisoner’s confinement. Alternatively, the Board argues that, if it must change petitioner’s terms of confinement to life with the possibility of parole or work release, then petitioner still is subject to consecutive 20-year minimum terms. The Board appears to argue that it may override the minimum terms and set a release date according to the matrix, but that it may do so only after a parole consideration hearing, which allows the Board to consider a variety of factors. See ORS 144.120 (1977) (describing parole release date hearing).”
Norris, 331 Or at 202-03 (emphasis and omission in original).
The court proceeded to construe ORS 163.105(4) (1977). Based on the statute’s text and context, it concluded that the board was required to make only one finding— *338whether an offender is capable of rehabilitation — and that, having found that an offender met that standard, the board was required to change the terms of the offender’s confinement to life with the possibility of parole. Norris, 331 Or at 203-07.
Having interpreted the statute, the court then applied it as follows:
“Applying that analysis to this case, we conclude that the Board must change the first of [the offender’s] life sentences to life with the possibility of parole or work release. [The offender] is entitled to have that change occur retroactively to January 26,1994, the date that the Board found him to be capable of rehabilitation. On that date, [the offender] began serving his second life sentence with a 20-year minimum term of confinement for his second conviction of aggravated murder. In 2009, 15 years from the date that he began serving that 20-year minimum term, petitioner may petition for a rehabilitation hearing, and that hearing also will be governed by ORS 163.105(3), (4), and (5) (1977). Only if the Board again finds that petitioner is capable of rehabilitation within a reasonable period of time, must the Board change petitioner’s second aggravated murder sentence to life with the possibility of parole and work release. Only at that point would petitioner become eligible for parole.
“In sum, in a rehabilitation hearing under ORS 163.105 (1977), the only finding that the Board must make is whether the prisoner is capable of rehabilitation. If the Board finds that the prisoner is capable of rehabilitation, then the Board must change the prisoner’s aggravated-murder sentence to life with the possibility of parole. In this case, petitioner received two life sentences without the possibility of parole for 20 years, the second sentence to be served consecutively to the first. Given its finding regarding petitioner’s capability of rehabilitation, the Board should have changed one of those sentences to life with the possibility of parole. Petitioner may petition for a second rehabilitation hearing after he serves 15 years of his second aggravated-murder sentence. ORS 163.105(3) (1977). Because petitioner is not eligible for parole unless the Board finds him capable of rehabilitation at that second hearing, we express no opinion in this case regarding either *339the applicability of the matrix or whether the Board erred in its findings in aggravation.”
Id. at 207-08 (emphasis added).
The state is correct that the primary issue presented by the parties in Norris was whether, under ORS 163.105(3) and (4) (1977), a finding that an offender is capable of rehabilitation necessarily results in the conversion of the offender’s sentence to life with the possibility of parole or whether that conversion depends on a separate finding by the board. And the court’s resolution of that issue is clear: only one finding is required — whether an offender is capable of rehabilitation — and that such a finding necessarily requires the board to convert the terms of the offender’s sentence to life “with the possibility of parole.” Norris, 331 Or at 207.
The remaining aspects of the court’s opinion are more problematic. As the foregoing quotation from the opinion plainly demonstrates, in applying its legal conclusions to the case before it, the court stated that, as of January 1994— the date that the board found the offender in that case to be capable of rehabilitation, and therefore also the date that the board was required to convert his sentence — the offender “began serving” his consecutive sentence. The court also stated that the offender could petition for a hearing in connection with his consecutive sentence in 2009. Those statements appear necessarily to rest on an understanding by the court that, as a matter of law, an offender subject to ORS 163.105(3) and (4) must automatically be released on parole in connection with the relevant sentence on the date on which the board finds that the offender is capable of rehabilitation and, concomitantly, converts the offender’s sentence. We can conceive of no other justification for the court’s statements.
The state may well be correct that the court’s statements appear to be at odds with other portions of the opinion in Norris. The court, for example, stated — twice—that, if the board later found that the offender was capable of rehabilitation in connection with his consecutive sentence, the offender would then become “eligible” for parole. Even more notably, the court specifically declined to express any opinion regarding the issue whether, if the board found the offender *340to be capable of rehabilitation in connection with his consecutive sentence, the parole matrix criteria would be applicable and the issue whether the board had erred in its previous findings regarding relevant factors under that matrix — questions that would not arise if, as a matter of law, a capable-of-rehabilitation finding and the concomitant conversion of the sentence resulted in automatic parole release. In a similar vein, there is some tension between the court’s conclusion in Norris that the offender was entitled to automatic parole release upon conversion of his first sentence and the legislature’s use, in ORS 163.105(3) and (4), of the phrase “possibility of parole.” (Emphasis added.) See Webster’s Third New Int'l Dictionary 1771 (unabridged ed 1993) (defining the noun “possibility” as a thing that is “possible whether theoretically, in general, or under a specified set of conditions” and as “a particular thing that may take place [or] eventuate,” and defining the adjective “possible” as indicating that a thing “may or may not occur” or is “dependent on contingency”).
Interestingly, in response to the offender’s petition for reconsideration in Norris, the state advanced that very argument to the Supreme Court, that is, that the court had addressed matters not discussed by the parties and had “miscontrue[d] the legal and practical effects” of a capable-of-rehabilitation finding. The state argued that, even after an offender has been determined capable of rehabilitation and the terms of the offender’s sentence have been converted to life with possibility of parole, the offender remains subject to the 20-year minimum as well as to further postponement of his or her parole release date. The court, however, denied the petition.
The dissent suggests that we may avoid the court’s holding in Norris merely by treating it as applicable only to the facts of that case, namely, when an offender has multiple consecutive ORS 163.105 sentences. As we understand it, the dissent contends that, in Norris, it was only because of the existence of the defendant’s second ORS 163.105 sentence and the need to make a capable-of-rehabilitation finding in relation to that sentence that “no [parole release] date could or would be set” on the first sentence. 194 Or App at 347 (Armstrong, J., concurring in part and dissenting in part).
*341The problems with the dissent’s suggestion are twofold. First, it does not so much provide an explanation of the inconsistencies in the court’s opinion in Norris as merely restate them. The dissent never explains why two consecutive ORS 163.105 sentences should be treated differently from each other, much less why we should treat the sentence in this case as being more like the second sentence in Norris — to which, the Supreme Court postulated, the parole matrix criteria might be applicable — than the first. For example, the dissent does not identify, and we do not discern, anything in ORS 163.105 itself that suggests that consecutive sentences imposed under that statute operate differently in relation to each other than do other consecutive indeterminate sentences.
Second, in suggesting that inconsistencies in Norris are attributable to the facts of that case, the dissent relies on a mistaken understanding of the board’s authority in regard to consecutive indeterminate sentences generally. In particular, in discussing the consequences of the consecutive sentences in Norris, the dissent characterizes the offender as being “not someone for whom the board could establish a parole release date.” 194 Or App at 347 (Armstrong, J., concurring in part and dissenting in part). However, the existence of a consecutive indeterminate sentence does not preclude the board from establishing a parole release date on the preceding indeterminate sentence; rather, it precludes only the offender’s actual release from prison. Thus, the parole board typically sets a prison term and a related parole release date as to each of multiple consecutive sentences. Cf. OAR 255-035-0021 (Dec 6, 1988) (establishing method for setting successive prison terms for each of several consecutive indeterminate sentences). Indeed, consistently with that general principle and with the even more basic principle that consecutive sentences do not run at the same time, it is not apparent to us how the offender in Norris could begin serving his consecutive sentence on a particular date, as ordered by the court, if he were not “released” on parole on that same date from service of the prison term of his first sentence— whether that “release” occurred automatically, as the Norris court apparently held, or through application of the parole *342matrix criteria, as the state argued was proper and as indisputably occurs in other contexts.
We are left, then, with the Norris court’s pronouncement that, on the date that the board made its finding that the offender was capable of rehabilitation, the offender began serving his consecutive sentence. Whether at odds with other portions of the opinion or not, the statement is part of the court’s disposition of the case. We therefore are constrained not to regard it as mere dictum; to the contrary, we are bound to follow it. Compare Gregory v. Salem General Hospital, 175 Or 464, 478, 153 P2d 837 (1944) (statements that were essential to the disposition of “an issue” were not dictum), with State v. Thompson, 166 Or App 370, 375, 998 P2d 762, rev den, 331 Or 192 (2000) (observation in another case was dictum where the observation pertained to a question that was not an issue in the other case and was not necessary in deciding the issue in that case), and Blanchard v. Kaiser Foundation Health Plan, 136 Or App 466, 470, 901 P2d 943, rev den, 322 Or 362 (1995) (where statement in a previous case was “entirely unnecessary to the disposition of the appeal,” statement was dictum and court was not bound by it). See also Napier v. Sheridan, 24 Or App 761, 772, 547 P2d 1399 (1976) (statement of Oregon Supreme Court, even though apparently dictum, was “clear and recent”; Court of Appeals therefore regarded itself as “bound” by statement). For the same reason, we are not at liberty to follow the alternative course suggested by the dissent: that, having discerned internal inconsistencies in the court’s opinion in Norris, we properly can choose to give effect to only those aspects of the opinion suggesting that a person found capable of rehabilitation of parole is merely eligible for, not entitled to, parole. 194 Or App at 349 (Armstrong, J., concurring in part and dissenting in part).
Accordingly, we conclude that, consistently with Norris, a finding by the board under ORS 163.105(3) and (4) (1983) that an offender sentenced under ORS 163.105 (1983) is capable of rehabilitation entitles the offender to immediate release on parole in connection with the relevant sentence. Conversely, the timing of the offender’s parole release is not subject to criteria set out in otherwise generally applicable statutes and rules relating to parole release, such as ORS *343144.120 (relied on by the state in Norris), ORS 144.125 (relied on by the state in this case), and OAR chapter 255.4
We note that this is not the first occasion on which we have considered the significance of Norris. Recently, in Larsen v. Board of Parole, 191 Or App 526, 84 P3d 176 (2004), we considered whether the standards and procedures set out in the applicable version of ORS 163.105 applied only in the “limited time frame” after the offender is permitted to petition for a hearing and before the offender has served the applicable 20- or 30-year minimum sentence under ORS 163.105(1) or (2). We concluded that it did not. In analyzing that issue, we stated:
“It is not disputed that the provisions of ORS 163.105(3) and (4) provide a basis for the board to, in essence, shorten the judicially imposed minimum sentences of 20 or 30 years. See Norris v. Board of Parole, 331 Or 194, 207-08, 13 P3d 104 (2000), cert den, 534 US 1028 (2001) (after serving 15 years, on date that petitioner had been found to be capable of rehabilitation pursuant to ORS 163.105(3), he was deemed to have completed the judicially imposed minimum portion of his sentence).”
Larsen, 191 Or App at 532.
Turning to the facts of this case, the parties do not dispute that the board found on February 15, 2000, that plaintiff was capable of rehabilitation. Under Norris, it follows that he was entitled as a matter of law to be released on parole in connection with the relevant sentence on that date. The trial court therefore erred in dismissing the writ of habeas corpus.
Our resolution on statutory grounds of plaintiffs first assignment of error obviates the necessity to consider plaintiffs constitutional challenges to the board’s action under that statute. In addition, because plaintiff sought no additional relief in his petition for alternative writ of mandamus, we need not address his second assignment of error, *344relating to the trial court’s dismissal of his petition for that writ. Finally, the state concedes that the trial court erred entering a money judgment against plaintiff in the amount of the filing fee in the mandamus proceeding in the absence of any findings respecting plaintiffs ability to pay that fee. We agree that the court erred, accept the state’s concession, and vacate the judgment on that ground. See State ex rel Baker v. Cook, 171 Or App 719, 16 P3d 1184 (2000).
Judgment in case number 00C20058 reversed and remanded. Money judgment in case number 01C19972 vacated and remanded, and otherwise affirmed.
As described above, this consolidated appeal arises out of plaintiffs habeas corpus and mandamus actions. For convenience, we refer to defendants in those actions — respectively, the superintendent of the Department of Corrections institution in which plaintiff was confined and the Board of Parole and Post-Prison Supervision — collectively as the state.
Apparently in the alternative, plaintiff argues that, even assuming that the parole matrix applies to him, he still is entitled to immediate release because application of the matrix in his case results in a prison term range of from 10 to 14 years and, by the time of his rehabilitation hearing in February 2000, he had served almost 16 years. Given our disposition, we do not reach that argument.
ORS 163.105 (1977) was identical in all relevant respects to the version of ORS 163.105 at issue here.
We express no opinion on the application of those statutes and rules in respects other than the timing of the offender’s release, such as administration of a psychological or psychiatric evaluation, the conduct of an exit interview, or the setting of parole conditions, see OAR chapter 255, so long as those functions do not impede the offender’s release on the proper parole release date, as discussed above.
