Petitioner killed a John Day police officer and later pleaded guilty to aggravated murder. ORS 163.095(2)(a)(A) (1991) (murder victim was police officer).1 In this parole review case, petitioner challenges the orders of the Board of Parole and Post-Prison Supervision that rescinded his scheduled release date from prison and that, after the release date had passed, reconvened a hearing to extend the release date. Petitioner makes three assignments of error. He asserts that (1) the board erred in rescinding the release date, (2) the board erred in postponing the release date, and (3) the board erred in “reconvening” an exit interview after his release date had passed. We review the board’s determinations for legal error, McClure v. Board of Parole, 236 Or App 606, 609, 237 P3d 879 (2010), rev den, 350 Or 241 (2011), and we reverse and remand.

In the early morning hours of April 8, 1992, Officer Ward arrived at petitioner’s home on a domestic violence call. Petitioner had been drinking and had assaulted his wife. When Ward tried to intervene, petitioner attacked him. Petitioner bludgeoned Ward with his fists and a 10-pound piece of firewood. At some point, petitioner took and discarded Ward’s gun outside the house. When other officers arrived, they found petitioner with blood on his hands and clothes. Ward was incapacitated, and, despite medical efforts to save him, he died soon thereafter.2 In 1994, petitioner pleaded guilty to aggravated murder.3 ORS 163.095(2)(a)(A).

At the time that petitioner was sentenced, ORS 163.105(l)(c) (1991) required the court to impose a life sentence with a 30-year minimum period of incarceration.4 *239However, the board was required, after 20 years and upon a prisoner’s petition, to “hold a hearing to determine if the prisoner is likely to be rehabilitated within a reasonable period of time.” ORS 163.105(2) (1991); see also Janowski/Fleming v. Board of Parole, 349 Or 432, 441-42, 245 P3d 1270 (2010). Petitioner submitted a petition, and, in July 2012, the board held a rehabilitation hearing. In an order known as a Board Action Form (BAF), dated July 18, 2012 (BAF #2), the board determined that petitioner had “satisfied the burden of proof * * * and therefore * * * is likely to be rehabilitated within a reasonable period of time and that the terms of confinement for the aggravated murder conviction should be changed to life imprisonment with the possibility of parole or work release.” The board’s order in July 2012 converted petitioner’s aggravated murder sentence to life with the possibility of parole.

In November 2012, the board held a prison-term hearing. See ORS 144.120(l)(a) (1991). The board calculated petitioner’s term of incarceration “under the matrix rules in effect at the time of his offense.” See Gordon v. Board of Parole, 343 Or 618, 622-23, 175 P3d 461 (2007) (explaining matrix system as sentencing scheme adopted by the legislature in 1977). In its BAF #3, the board set a “projected parole release date” of June 7, 2013, following a period of incarceration of254 months. In contemplation of that release date, the board required that petitioner complete a psychological evaluation and participate in an exit interview with the board. See ORS 144.223 (psychological examination of parole candidate).

On February 13, 2013, the board held the exit interview, as allowed by ORS 144.125 (1991).5 The board observed that petitioner’s psychological evaluation included a diagnosis of antisocial personality disorder and alcohol dependence in remission.6 After considering the evidence, the board *240affirmed petitioner’s release date of June 7, 2013. Its order, BAF #4, stated, in part:

“Based on the doctor’s report and diagnosis, coupled with all the information that the Board is considering, the Board concludes that the inmate does have an emotional disturbance; however, the emotional disturbance is not presently so severe as to constitute a danger to the health and safety of the community. The Board has considered this matter under the substantive standard in effect at the time of the commitment offense(s) and all other applicable rules and laws.”

On June 4, 2013, a few days before petitioner’s planned release, the board issued an order that “rescind [ed] the parole release date” and “reopen[ed]” its prior decision.7 The board’s BAF #5 stated that the board “on its own motion, rescinds the parole release date of June 7, 2013, and pursuant to its authority in OAR 255-080-0012(2),8 reopens Board Action Form (BAF) #4 for reconsideration. A new psychological evaluation will be obtained and the exit interview hearing will be reconvened * * * ” The order was corrected in BAF #6. As a consequence, petitioner was not released on June 7, 2013.

On September 30, 2013, the board conducted a new exit interview and issued an order (BAF #7), in which the board reaffirmed its decision to rescind petitioner’s release date.9 Contrary to its prior finding in BAF #4, the board *241found that petitioner “suffers from a present severe emotional disturbance such as to constitute a danger to the health or safety of the community.” The board extended petitioner’s release date 24 months.

Petitioner sought administrative review of the board’s decisions. On review, the board determined that it had authority under OAR 255-080-0012(2) to reopen the case for reconsideration and under OAR 255-080-0012(3)(c) to schedule a reopened hearing.10 In response to petitioner’s due process argument, the board concluded that it had provided adequate process by reconvening a hearing so that he could “present information and [respond] to the information submitted by others.” The board explained in its second administrative review response that in reaching its new determination that petitioner had a present severe emotional disturbance, the board had considered and relied upon, at least in part, documents submitted after petitioner’s February exit interview, including “the DA submission of documents showing a history of assault on [petitioner’s] ex-wife.” The board noted that it had “received and reviewed a large amount of significant information” and that it had relied on that “new information that was received.”

Petitioner now seeks judicial review, contending, generally, that he was entitled to a hearing before the board rescinded his release date, or, in absence of that hearing, that he was entitled to be released under the earlier order. Making three arguments, he asks that the board’s orders be reversed and remanded with instructions to reinstate the order affirming his release date. First, he contends that, by reopening the process and rescinding his release date, the board violated OAR 225-080-0012 and OAR 255-060-0006(1). Second, he contends that the board’s action violated ORS 144.125 (1991) because the board did not postpone his release date for a permissible reason under that statute. Third, he contends that the board violated his constitutional *242rights to due process under the Fourteenth Amendment to the United States Constitution by depriving him of a liberty interest — that is, his scheduled release date.

We begin by describing the statutory scheme applicable to this case. At ORS 144.245(1) (1991), Oregon statute requires that, “when the parole board ‘has set a date on which a prisoner is to be released upon parole, the prisoner shall be released on that date unless the prisoner on that date remains subject to an unexpired minimum term.’” Engweiler v. Persson / Dept. of Corrections, 354 Or 549, 563, 316 P3d 264 (2013) (quoting ORS 144.245(1)). Release is not guaranteed to an inmate under that statutory provision, because, under ORS 144.125 (1991), “[p]rior to the scheduled release of any prisoner on parole * * * the board may * * * on its own initiative interview the prisoner to review the prisoner’s parole plan and psychiatric or psychological report, if any, and the record of the prisoner’s conduct during confinement.” That review process “exists to ensure that offenders are not released to parole unless and until the board is satisfied that their release is consistent with community safety.” Engweiler, 354 Or at 567.

The board’s review process, however, is bound by statutory limitations. The Supreme Court has explained:

“Once a [release] date is set, it can be postponed only for three statutorily prescribed reasons. First, under ORS 144.125(2) (1985), the board must postpone a prisoner’s release date if it finds that the prisoner had engaged in serious misconduct during confinement. The board also is permitted, but not required, to postpone a release date if the prisoner received a psychiatric or psychological diagnosis of a severe emotional disturbance that would make him a danger to the community, ORS 144.125(3) (1985), or if it deems the prisoner’s release plan to be inadequate, ORS 144.125(4) (1985).”

Janowski/Fleming, 349 Or at 457 (emphasis added); see also Stogsdill v. Board of Parole, 342 Or 332, 336, 154 P3d 91 (2007) (petitioner “entitled to be released unless the board is persuaded that he has a present severe emotional disturbance that constitutes a danger to the health or safety of the community”). Therefore, “ [i] n the absence of one of those *243[three] grounds for postponement, the inmate has a legal right to release on the scheduled release date.” Gordon, 343 Or at 622 (citing ORS 144.245(1); Hamel v. Johnson, 330 Or 180, 187, 998 P2d 661 (2000)).11

In this case, the board had set a release date for June 7, 2013. Just before, the board summarily “rescinded” and, as a practical consequence, postponed that release date without prior notice or hearing.12 The board did so, at that time, without making one of the three determinations necessary under ORS 144.125(1) (1991) for an extension of a release date. The state argues that the hoard had the authority to do so under OAR 255-080-0012.13 By its own terms, that administrative rule does not authorize the board to rescind a release date without a hearing. Beveridge v. Johnson, 157 Or App 57, 62-63, 967 P2d 1238 (1998). And, a faulty procedure is not excused by invoking the need for a belated psychological exam. Id. at 62 n 5. (ORS 144.125(4), ORS 144.223(1), and OAR 255-060-0008 “do not demonstrate the board’s authority to rescind the parole date in order to conduct a psychological exam” (emphasis in original)). The state does not identify any other authority permitting it “to rescind a parole release date for the purpose of conducting a psychological review.” Id. at 63. Therefore, the board’s order rescinding petitioner’s release date under OAR 255-080-0012(2) and reopening the case for reconsideration under OAR 255-080-0012(3)(c) was in error. See Talbott v. Teacher Standards and Practices Comm., 260 Or App 355, 373, 317 P3d 347 (2013) (“We accept any ‘plausible interpretation’ by an agency of its own administrative rule as long *244as the interpretation is not ‘inconsistent’ with * * * any other source of law.”). Compliance with ORS 144.125(1) (1991) was necessary.

The state relies on our decision in Murphy v. Board of Parole, 140 Or App 642, 643, 915 P2d 489, modified on recons, 143 Or App 605, 925 P2d 98, rev den, 324 Or 464 (1996), to argue that we should nevertheless affirm, because petitioner was later given the hearing to determine whether he had a psychological diagnosis of a present severe emotional disturbance that would make him a danger to the community.14 The state’s reliance on Murphy ignores subsequent changes in the law regarding the proper remedy in cases in which a petitioner’s release date has elapsed. In a later case, Hamel, 330 Or at 187-88, the Supreme Court explained:

“ [A] fter petitioner had arrived in the corrections facility, the Board held a hearing to set his initial parole release date. Applying the matrix range, the Board set May 29, 1997, as petitioner’s initial release date. Under ORS 144.245(1), the Board was required to release petitioner on parole on that date unless the Board identified a valid reason for postponing his release. In 1997, the Board issued an order identifying one of the statutory reasons for postponing petitioner’s parole release date, namely, that he suffered from ⅛ present severe emotional disturbance [sic] that constitutes a danger to the health or the safety of the community.’

*245“In his habeas corpus petition, petitioner alleged that the reason that the Board gave for postponing his release date was not valid. *** [UJnder ORS 144.245, the Board was required to release petitioner on parole on the scheduled release date unless it had a valid reason for postponing that release date. Respondent does not contend that petitioner was subject to an unexpired minimum term. Therefore, if petitioner were to prevail on his claim that the Board’s reason for postponing his release date under ORS 144.125(3) was not valid, then the Board should have released him on parole on May 29, 1997, and his continued imprisonment is unlawful. The Board is not entitled to rely on evidence and reasons that it acquired after that date to justify its decision not to release petitioner then. In other words, * * * the Board could not rely on petitioner’s 1998 psychological evaluation to justify its decision to postpone petitioner’s 1997 parole release date.”

(Emphasis added.) We have understood Hamel to mean that, “if a release date was scheduled and elapsed without the board first having found a valid reason to postpone release, but the inmate was erroneously not released, later events cannot furnish a basis for postponing release; the inmate is entitled to immediate release.” Rivas v. Persson, 256 Or App 829, 835-36, 304 P3d 765 (2013), rev dismissed, 354 Or 841 (2014) (emphasis added).

Likewise, in this case, the board lacked authority to postpone petitioner’s release date, absent a timely hearing and a timely finding under ORS 144.125 (1991). After that release date had passed, it does not suffice to later find a reason to have postponed his release. See Atkinson v. Board of Parole, 280 Or App 410, 419, 382 P3d 567 (2016). The board failed to release petitioner on his scheduled release date. Therefore, we reverse and remand with a direction that the board reinstate petitioner’s release date as last lawfully provided in BAF #3 and #4.

Reversed and remanded.
