I interpret Penal Code section 645, subdivision (a)1 to authorize the Board of Prison Terms (BPT) in the normal course of its imposition of parole conditions to include medroxyprogesterone acetate (MPA) treatment2 as a parole condition, subject to prior court approval;3 it does not authorize a trial court at sentencing to impose MPA treatment as a parole condition. Therefore, I believe the trial court imposed an unauthorized sentence by ordering Foster to undergo section 645 MPA treatment on his parole release.
A
Section 645 was enacted in 1996 and states:
“(a) Any person guilty of a first conviction of any offense specified in subdivision (c), where the victim has not attained 13 years of age, may, upon *253parole, undergo medroxyprogesterone acetate treatment or its chemical equivalent, in addition to any other punishment prescribed for that offense or any other provision of law, at the discretion of the court.
“(b) Any person guilty of a second conviction of any offense specified in subdivision (c), where the victim has not attained 13 years of age, shall, upon parole, undergo medroxyprogesterone acetate treatment or its chemical equivalent, in addition to any other punishment prescribed for that offense or any other provision of law.
“(c) This section shall apply to the following offenses:
“(1) Subdivision (c) or (d) of Section 286.
“(2) Paragraph (1) of subdivision (b) of Section 288.
“(3) Subdivision (c) or (d) of Section 288a.
“(4) Subdivision (a) or (j) of Section 289.
“(d) The parolee shall begin medroxyprogesterone acetate treatment one week prior to his or her release from confinement in the state prison or other institution and shall continue treatments until the Department of Corrections demonstrates to the Board of Prison Terms that this treatment is no longer necessary.
“(e) If a person voluntarily undergoes a permanent, surgical alternative to hormonal chemical treatment for sex offenders, he or she shall not be subject to this section.
“(f) The Department of Corrections shall administer this section and implement the protocols required by this section. Nothing in the protocols shall require an employee of the Department of Corrections who is a physician and surgeon ... to participate against his or her will in the administration of the provisions of this section. These protocols shall include, but not be limited to, a requirement to inform the person about the effect of hormonal chemical treatment and any side effects that may result from it. A person subject to this section shall acknowledge the receipt of this information.”
Neither the majority nor the parties have cited, and I have not found, any cases construing the language of or otherwise considering section 645. Section 645, subdivision (a) does not specify either the time when or manner *254in which a trial court is to exercise its discretion to permit a parole condition of MPA treatment, and its interpretation appears to be an issue of first impression.
B
The conventional wisdom is that “[t]he goal of statutory construction is to ascertain and effectuate the intent of the Legislature. [Citation.] Ordinarily, the words of the statute provide the most reliable indication of legislative intent. [Citation.] When the statutory language is ambiguous, the court may examine the context in which the language appears, adopting the construction that best harmonizes the statute internally and with related statutes. [Citations.]” (Pacific Gas & Electric Co. v. County of Stanislaus (1997) 16 Cal.4th 1143, 1152 [69 Cal.Rptr.2d 329, 947 P.2d 291].) A statute must be considered as a whole and harmonized so far as possible with other statutory provisions. (1 Witkin & Epstein, Cal. Criminal Law (3d ed. 2000) Introduction to Crimes, § 26, p. 55.) “ ‘[A] statute should be construed with reference to the entire statutory system of which it forms a part in such a way that harmony may be achieved among the parts . . . .’ ” (People ex rel. Younger v. Superior Court (1976) 16 Cal.3d 30, 40 [127 Cal.Rptr. 122, 544 P.2d 1322]; see also Terhune v. Superior Court (1998) 65 Cal.App.4th 864, 876-877 [76 Cal.Rptr.2d 841].)
When statutory language is susceptible of more than one reasonable interpretation, a court may “resort to extrinsic sources, including the ostensible objects to be achieved and the legislative history” to assist it in construing ambiguous language. (People v. Coronado (1995) 12 Cal.4th 145, 151 [48 Cal.Rptr.2d 77, 906 P.2d 1232].) A statute “should be interpreted to make it valid and effective, and a construction favoring constitutionality is preferred. [Citations.]” (1 Witkin & Epstein, supra, § 27, p. 56.) A statute susceptible of two constructions should be interpreted, if reasonably possible, to avoid serious and doubtful constitutional questions. (People v. Birks (1998) 19 Cal.4th 108, 135 [77 Cal.Rptr.2d 848, 960 P.2d 1073].) A statute should also be “construed to avoid an absurd or bizarre result.” (1 Witkin & Epstein, Cal. Criminal Law, supra, § 27, p. 57.) If a statute is susceptible of more than one reasonable interpretation, the interpretation that results in the more sensible or pragmatic construction should be adopted. (Id. at § 32, pp. 62-63.)
The rule of lenity provides that “[w]hen faced with an ambiguous statute and no extrinsic indicia of legislative intent, courts are required to construe a criminal law ‘as favorably to the defendant as its language and intent will reasonably permit.’ [Citation.] ‘ “The defendant is entitled to the benefit of *255every reasonable doubt, whether it arise[s] out of a question of fact, or as to the true interpretation of words or the construction of language used in a statute.” ’ [Citation.]” (People v. Douglas (2000) 79 Cal.App.4th 810, 815 [94 Cal.Rptr.2d 500].) The rule of lenity applies only when there are two equally plausible interpretations of the statute. (Ibid.; People v. Prothero (1997) 57 Cal.App.4th 126, 131 [66 Cal.Rptr.2d 779]; In re Christian S. (1994) 7 Cal.4th 768, 780 [30 Cal.Rptr.2d 33, 872 P.2d 574].)
C
Although the parties apparently assume that section 645 authorizes imposition of MPA treatment only as a condition of parole, I consider the foundational issue to be whether MPA treatment is only a condition of parole that applies during a defendant’s parole period or whether MPA treatment can be imposed on a defendant not as a condition of parole but as part of the sentence that begins one week prior to release on parole and continues potentially for his or her lifetime. If the former, then imposition of MPA treatment as part of a sentence is unauthorized. Section 645, subdivision (a) does not contain any language that expressly resolves this issue. It simply provides that a person who commits a qualifying offense “may, upon parole, undergo [MPA] treatment. . . .” (§ 645, subd. (a).) However, other section 645 provisions support the conclusion that MPA treatment is only a condition of parole that terminates on or before expiration of a defendant’s parole period. Section 645, subdivision (d) provides: “The parolee shall begin [MPA] treatment one week prior to his or her release from confinement in the state prison or other institution and shall continue treatments until the Department of Corrections demonstrates to the [BPT] that this treatment is no longer necessary.” (Italics added.) By referring to a person subject to section 645 MPA treatment as a parolee, it appears the Legislature intended MPA treatment to be imposed only on parolees and therefore only as a condition of parole during parolees’ parole periods (and one week prior thereto). Furthermore, by requiring MPA treatment to continue until the Department of Corrections (CDC) demonstrates to the BPT that it is no longer necessary, it appears the Legislature intended MPA treatment to continue only so long as the CDC and BPT would normally have supervisory authority or jurisdiction over a parolee. Because the CDC and BPT do not have authority or jurisdiction over a parolee after the parolee’s parole period has expired, it is implicit that MPA treatment must cease on or before expiration of his or her parole period. Furthermore, section 645, subdivision (f) provides: “The [CDC] shall administer this section and implement the protocols required by this section. . . .” That provision means the CDC is charged with responsibility to provide the MPA treatment to parolees and otherwise administer or supervise the treatment program. Because the CDC does not have authority or jurisdiction to provide treatment or otherwise *256supervise persons other than inmates or parolees during their imprisonment and parole periods, it is implicit that the CDC’s section 645 administration responsibility applies only during parolees’ parole periods (and one week prior thereto) and not after expiration of their parole periods. I conclude that under section 645, MPA treatment is a condition of parole that applies only during a defendant’s parole period (and one week prior thereto) and not thereafter. If the Legislature had intended MPA treatment to potentially continue after expiration of a defendant’s parole period, it could have so provided in a manner similar to the language in section 290 requiring a sex offender to register with local law enforcement agencies during the offender’s lifetime.4
D
Because section 645 MPA treatment applies only as a condition of parole, the next issue is when that parole condition may be imposed -under section 645, subdivision (a). Foster and the People assert, and the majority concludes, that section 645, subdivision (a) provides for imposition of MPA treatment as a parole condition by a trial court at the time of sentencing. However, section 645, subdivision (a) does not expressly state the time when a trial court is authorized to exercise its discretion to approve MPA treatment as a condition of parole. It simply states: “Any person guilty of a first conviction of any offense specified in subdivision (c) . . . may, upon parole, undergo [MPA] treatment or its chemical equivalent, in addition to any other punishment prescribed for that offense or any other provision of law, at the discretion of the court.” (§ 645, subd. (a), italics added.) That language can reasonably be construed as authorizing a trial court to approve MPA treatment as a condition of a defendant’s parole either (1) on sentencing a defendant, or (2) on the request of the BPT shortly before a defendant’s release on parole.
Because the legislative intent of section 645, subdivision (a) is not clear from its text, I consider extrinsic sources and apply other rules of statutory construction to determine that legislative intent. (People v. Coronado, supra, *25712 Cal.4th at p. 151.) One rule of statutory construction is that a statute generally should be construed in a manner that best harmonizes the statute with other relevant statutes. (Pacific Gas & Electric Co. v. County of Stanislaus, supra, 16 Cal.4th at p. 1152; People ex rel. Younger v. Superior Court, supra, 16 Cal.3d at p. 40; Terhune v. Superior Court, supra, 65 Cal.App.4th at pp. 876-877.)
The Penal Code provides that parole conditions generally are imposed by the BPT. “[T]he Legislature has given the [BPT] expansive authority ... to impose any parole conditions it deems proper. [Citations.]” (Terhune v. Superior Court, supra, 65 Cal.App.4th at p. 874.) Section 3000, subdivision (b)(7) provides: “For purposes of this chapter, the [BPT] shall be considered the parole authority.” Section 3053, subdivision (a) provides: “The [BPT] upon granting any parole to any prisoner may also impose on the parole any conditions that it may deem proper.” (Italics added.) Section 3000, subdivision (b)(4) provides: “The parole authority [i.e., BPT] shall consider the request of any inmate regarding the length of his or her parole and the conditions thereof.” (Italics added.) The BPT normally establishes and imposes conditions of parole shortly before an inmate is released on parole. Section 3000, subdivision (b)(6) reflects that timing, providing: “The [CDC] shall meet with each inmate at least 30 days prior to his or her good time release date and shall provide, under guidelines specified by the parole authority [i.e., BPT], the conditions of parole and the length of parole up to the maximum period of time provided by law. The inmate has the right to reconsideration of the length of parole and conditions thereof by the parole authority. . . .” Furthermore, regulations reflect that the BPT is the “administrative board responsible for setting parole dates, establishing parole length and conditions . . . .” (Cal. Code Regs., tit. 15, § 2000, subd. (b)(11), italics added.) Also, “[s]pecial conditions [of parole] may be established and imposed by the [CDC] or the [BPT] . . . .” (Id. at § 2513.) Under these statutes and regulations it generally is the responsibility of the BPT, and within its power and authority, to establish conditions for an inmate’s parole. (Terhune, supra, at pp. 874, 878; People v. Burgener (1986) 41 Cal.3d 505, 531 [224 Cal.Rptr. 112, 714 P.2d 1251], disapproved on other grounds in People v. Reyes (1998) 19 Cal.4th 743, 753 [80 Cal.Rptr.2d 734, 968 P.2d 445]; 5 Erwin et al., Cal. Criminal Defense Practice (2002) Parole, § 104.05[4][a], p. 104-34; Levenson, Cal. Criminal Procedure (2000) Parole, §§ 31:2, 31:3, pp. 1183-1184.) One authority notes: “Conditions of parole are specified by the [BPT]. Pursuant to the supervisory power of the state over parolees, the [BPT] may impose any conditions it deems proper, and must impose statutory conditions if applicable.” (Levenson, supra, at § 31:7, p. 1187, fns. omitted.) Therefore, unless a statute expressly requires a specific condition of parole, the BPT generally has the power and discretion to impose conditions on an inmate’s parole.
*258Because section 3000 et seq. provides that the BPT generally is charged with the authority to impose conditions of parole, it is consistent with this statutory scheme to construe section 645, subdivision (a) to provide that the BPT has the authority to impose MPA treatment as a condition of parole but, because of the serious nature of MPA treatment, require the BPT to obtain prior court approval of the BPT’s imposition of that condition. Because the BPT normally establishes conditions of parole shortly before a defendant’s release on parole (see, e.g., §§ 3000, subd. (b), 3053, subd. (a)), if the BPT deems section 645 MPA treatment to be an appropriate condition of a defendant’s parole, it could petition a trial court for approval in its discretion of imposition of that condition during the BPT’s normal course of establishing conditions of parole for that defendant. The majority’s interpretation of section 645, subdivision (a) to provide that MPA treatment may be imposed by the trial court at the time of sentencing conflicts with the general statutory scheme that the BPT is charged with imposing conditions of parole. Under the majority’s time of sentencing interpretation, it is the prosecutor, not the BPT, who requests at a defendant’s sentencing that the trial court impose MPA treatment as a condition of the defendant’s parole.5 The majority’s time of sentencing interpretation, in effect, makes the prosecutor and/or trial court the parole authority, contradicting section 3000, subdivision (b)(7), which provides that the BPT is the parole authority with power to establish and impose conditions of parole. Furthermore, the timing of the imposition of parole conditions at sentencing is drastically different from the statutory scheme. Rather than providing for the imposition of MPA treatment as a parole condition shortly before a defendant’s release on parole, the time of sentencing interpretation provides for imposition of a parole condition typically many years before the BPT imposes other conditions of parole. For example, in this case the trial court imposed MPA treatment as a condition of Foster’s parole approximately 24 years before the earliest date on which he could be released on parole. It is foreseeable that some defendants who are subject to section 645 may not be released on parole for 40, 50, 60 or more years after their sentencing. It seems premature to establish a discretionary condition of parole like MPA treatment under section 645, subdivision (a) so far in advance of the imposition of other conditions of parole and a defendant’s release on parole.
Furthermore, the majority’s time of sentencing interpretation of section 645, subdivision (a) is inconsistent with section 645, subdivision (b). The parole conditions imposed by the BPT must include any statutorily required conditions in effect at the time of commencement of parole. (See Levenson, *259Cal. Criminal Procedure, supra, § 31:7, p. 1187.) For example, section 3053.5 requires a parole condition of abstinence from alcohol use for section 290 sex offenders who have been found to have committed their offenses while intoxicated or addicted to excessive use of alcohol. Section 645, subdivision (b) provides a required MPA treatment parole condition for parolees who have incurred a second conviction of the same specified sex offenses that invoke the application of subdivision (a). However, the statutorily imposed parole conditions are those in effect at the time of commencement of parole. Therefore, had Foster incurred a second conviction for a specified offense, his parole conditions would include MPA treatment only if section 645, subdivision (b) remained in effect at the time of his parole. However, under the time of sentencing interpretation of section 645, subdivision (a), his parole conditions include MPA treatment even if section 645 is not in effect at the time of his parole. I perceive no logical reason to have parole conditions imposed at sentencing if the defendant has a first conviction but imposed only at the time of parole if the defendant has a second conviction. Interpretation of section 645, subdivision (a) to provide for imposition of MPA treatment at the time of imposition of other parole conditions is supported by the rule that a statute should be construed, if possible, to support harmony and consistency with other relevant statutes. (Pacific Gas & Electric Co. v. County of Stanislaus, supra, 16 Cal.4th at p. 1152; People ex rel. Younger v. Superior Court, supra, 16 Cal.3d at p. 40; Terhune v. Superior Court, supra, 65 Cal.App.4th at pp. 876-877.)
A rule of construction is that statutes should be interpreted pragmatically to avoid absurd or bizarre results. (1 Witkin & Epstein, Cal. Criminal Law, supra, §§ 27, 32, pp. 57, 62-63.) The majority’s imposition at time of sentencing interpretation of section 645, subdivision (a) has a highly unusual and absurd result. A prosecutor could request, and a trial court could order on that request or sua sponte, MPA treatment as a condition of parole for a defendant who may not be released on parole for many years after sentencing. In contrast, imposition of an MPA treatment parole condition at the time of parole is more pragmatic and more closely follows the usual scheme pursuant to which the BPT establishes and imposes conditions of parole shortly before a defendant is released on parole. (Terhune v. Superior Court, supra, 65 Cal.App.4th at pp. 874, 878; People v. Burgener, supra, 41 Cal.3d at p. 531.) The BPT presumably will be in a better position to determine shortly before a defendant’s parole whether a defendant should be subject to MPA treatment as a condition of parole than the prosecutor and trial court at the time of the defendant’s sentencing. In addition, the purpose of an MPA treatment parole condition is to lessen the probability of reoffense following release from prison. That purpose is best served by evaluation at the time of parole of the defendant and the then available treatments. MPA treatment *260may be the most effective treatment available now, but it is presumptuous to conclude it will remain so at the time of a defendant’s release on parole.
Section 645’s legislative history does not provide assistance in construing the ambiguity of section 645, subdivision (a). Neither the majority nor the parties cite, and I am unaware of, any legislative history of section 645 that contradicts a time of parole construction of section 645, subdivision (a). Furthermore, the time of parole construction of section 645, subdivision (a) avoids, at least for the present time, the serious constitutional issue whether MPA treatment is cruel and unusual punishment in violation of the state and federal Constitutions. (People v. Birks, supra, 19 Cal.4th at p. 135.) Although both Foster and the People ask this court to decide that issue in this appeal, the time of parole construction of section 645, subdivision (a) avoids a premature determination of that serious issue.
Finally, because both alternative interpretations of the ambiguous language of section 645, subdivision (a) are arguably plausible, the rule of lenity should be applied in this case. The rule of lenity requires that a court construe an ambiguous criminal statute as favorably to the defendant as its language and intent will reasonably permit. (People v. Douglas, supra, 79 Cal.App.4th at p. 815; People v. Prothero, supra, 57 Cal.App.4th at p. 131; In re Christian S., supra, 1 Cal.4th at p. 780.) A time of parole interpretation of section 645, subdivision (a) is more favorable to a defendant than the majority’s alternative time of sentencing interpretation. A defendant normally would prefer to have consideration of imposition of MPA treatment as a parole condition postponed as long as possible before he or she is released on parole. Because a defendant’s personal circumstances near the time of his or her release on parole and the then current scientific consensus as to the advisability of MPA treatment may ultimately weigh against a decision to impose MPA treatment as a condition of parole, postponement of that decision from the time of sentencing until shortly before a defendant’s release on parole generally would favor the defendant. Also, a defendant may prefer that the BPT, rather than the prosecutor or sentencing trial court, make the initial decision whether MPA treatment should be imposed as a condition of parole, subject to a trial court’s discretionary approval of that parole condition. The rule of lenity supports a time of parole construction of section 645, subdivision (a).
I believe section 645, subdivision (a) authorizes the imposition of an MPA treatment parole condition by the BPT in the normal course of the BPT’s imposition of other parole conditions, subject to prior court approval obtained shortly before a defendant’s release on parole. The majority, the People and Foster do not provide any persuasive support for a contrary construction of section 645, subdivision (a).
*261At Foster’s sentencing the trial court, as part of the sentence, imposed section 645 MPA treatment as a condition of his parole, which apparently could not occur for at least 24 years. However, under the time of parole construction of section 645, subdivision (a), the court did not have jurisdiction or other authority to impose that parole condition at Foster’s sentencing. The trial court’s discretion to order MPA treatment arises only if and when the BPT petitions the court for approval of imposition of that parole condition shortly before Foster’s release on parole.
Although the majority concludes Foster waived his right to appeal the trial court’s imposition at his sentencing of section 645 MPA treatment as a condition of his parole, an appellate court may, and I believe should, review any contention that the sentence imposed is unauthorized. “In passing sentence, the [trial] court has a duty to determine and impose the punishment prescribed by law. [Citations.]” (People v. Cattaneo (1990) 217 Cal.App.3d 1577, 1589 [266 Cal.Rptr. 710].) “[A] sentence is generally ‘unauthorized’ where it could not lawfully be imposed under any circumstance in the particular case. Appellate courts are willing to intervene in the first instance because such error is ‘clear and correctable’ independent of any factual issues presented by the record at sentencing. [Citation.]” (People v. Scott (1994) 9 Cal.4th 331, 354 [36 Cal.Rptr.2d 627, 885 P.2d 1040].) “A claim that a sentence is unauthorized . . . may be raised for the first time on appeal, and is subject to judicial correction whenever the error comes to the attention of the reviewing court. [Citations.]” (People v. Dotson (1997) 16 Cal.4th 547, 554, fn. 6 [66 Cal.Rptr.2d 423, 941 P.2d 56]; see also In re Ricky H. (1981) 30 Cal.3d 176, 191 [178 Cal.Rptr. 324, 636 P.2d 13]; People v. Serrato (1973) 9 Cal.3d 753, 764 [109 Cal.Rptr. 65, 512 P.2d 289]; People v. Martinez (1998) 65 Cal.App.4th 1511, 1519 [77 Cal.Rptr.2d 492]; People v. Miles (1996) 43 Cal.App.4th 364, 367 [51 Cal.Rptr.2d 87].) In People v. Mustafaa (1994) 22 Cal.App.4th 1305 [28 Cal.Rptr.2d 172], which involved a guilty plea by the defendant, we noted that a trial court’s “fashioning a sentence in a manner [that] is unauthorized by law exceeds the jurisdiction of the court and may be the subject of later review even though no objection was made in the trial court. [Citation.]” (Id. at p. 1311.) In People v. Davis (1981) 29 Cal.3d 814 [176 Cal.Rptr. 521, 633 P.2d 186], the Supreme Court reversed the trial court’s imposition of a sentence that exceeded the punishment authorized by statute, noting it was jurisdictional error that was subject to correction on appeal. (Id. at pp. 827-832.) Furthermore, Davis concluded the statute was ambiguous and should be interpreted favorably to the defendant. (Id. at pp. 828-832.)
Because an unauthorized sentence may be corrected on appeal, I disagree with the majority’s conclusion that Foster is precluded from challenging the *262trial court’s imposition at his sentencing of section 645 MPA treatment as a condition of his parole. People v. Panizzon (1996) 13 Cal.4th 68 [51 Cal.Rptr.2d 851, 913 P.2d 1061] does not support the majority’s position because in Panizzon the sentence imposed pursuant to the defendant’s plea bargain did not exceed the sentence authorized by statute. (Id. at p. 88.) Based on the time of parole construction of section 645, subdivision (a), the trial court imposed an unauthorized sentence Foster may challenge on appeal (U.S. v. Marin (4th Cir. 1992) 961 F.2d 493, 496) and this court can correct on appeal (People v. Dotson, supra, 16 Cal.4th at p. 554, fn. 6).
I conclude the trial court erred by entering the judgment to the extent it imposed at Foster’s sentencing section 645 MPA treatment as a condition of Foster’s parole. I would modify the judgment by striking the trial court’s order imposing section 645 MPA treatment as a condition of Foster’s parole.
Appellant’s petition for review by the Supreme Court was denied November 13, 2002. Kennard, J., and Moreno, J., were of the opinion that the petition should be granted.
All statutory references are to the Penal Code unless otherwise specified.
MPA treatment on males generally has the effect of lowering their testosterone hormone levels, resulting in reduced sexual urges. (People v. Gauntlett (1984) 134 Mich.App. 737 [352 N.W.2d 310, 314-315]; Gimino, Mandatory Chemical Castration for Perpetrators of Sex Offenses Against Children: Following California’s Lead (1997) 25 Pepperdine L.Rev. 67, 73-75.) MPA treatment is commonly referred to as hormone suppression treatment or “chemical castration.” (Gimino, supra, at pp. 74-75; Gauntlett, supra, at p. 315.)
Because both parties restricted their discussions in their appellate briefs to the issue of whether MPA treatment is cruel and unusual punishment under the state and federal Constitutions, we requested, and the parties submitted, supplemental briefing on the issue of “whether Penal Code section 645, subdivision (a) should be interpreted as authorizing the Board of Prison Terms to apply, shortly before a defendant is released from prison on parole, to the trial court for an order imposing as a condition of the defendant’s parole the treatment specified in that statute.” Both parties assert in their supplemental briefs that section 645, subdivision (a) should not be interpreted in this manner.
Section 290 provides: “(a)(1)(A) Every person described in paragraph (2), for the rest of his or her life while residing in . . . California. . . shall be required to register with the chief of police of the city in which he or she is residing . . . .” (Italics added.) Section 290 provides that a sex offender’s parole shall be revoked by the parole authority if he or she fails to register as required. (§ 290, subd. (h).) Section 290 also provides that a felony sex offender’s willful failure to register as required constitutes a felony offense punishable by a prison term of up to three years. (§ 290, subd. (g)(2).) Therefore, section 290’s registration requirement is not only a condition of parole but also is an independent requirement that applies after expiration of the parole period. In contrast, section 645 does not provide for MPA treatment for a defendant’s lifetime or create a separate offense for refusing treatment. Therefore, it is implicit that under section 645 MPA treatment may be required only as a condition of parole during a defendant’s parole period (and one week prior thereto).
It is also possible under the time of sentencing interpretation that the trial court, on sentencing a defendant, could sua sponte impose MPA treatment as a condition of the defendant’s parole.
