¶ 1. In this interlocutory appeal, Wilbert L. Thomas argues that the circuit court erred by not granting his motion to dismiss a December 28, 1999 petition seeking his commitment as a WlS. Stat. ch. 980 (1997-98) 1 sexually violent person. Thomas argues that the petition should have been dismissed for nоt conforming to the time limit in WlS. Stat. § 980.02(2)(ag) because it was filed after he had been discharged from his criminal sentence for a sexually violent offense. After reviewing the statute, we agree *219 and conclude that an offender cannot be detained beyond his or her maximum discharge date in order to file a ch. 980 petition. The order is reversed.
¶ 2. Thomas was convicted of second-degree sexual assault on March 31,1992, and sentenced to serve eight years in prison. His mandatory release date was December 23, 1997. After a psychological evaluation prior to his release, the evaluating psychologist determined that Thomas did not meet the criteria for Wis. Stat. ch. 980 commitment, and therefore the Department .of Corrections (DOC) dеclined to request that such petition be filed. The Racine district attorney's office had another psychological evaluation conducted and, after the psychologist recommended that it do so, filed a petition on Decembеr 8,1997, to commit Thomas under ch. 980. Thomas moved to dismiss the petition, asserting that the district attorney did not have authority to file a petition unless the DOC had requested that the petition be filed and the Department of Justice (DOJ) had declined to do so. The cоurt denied Thomas's motion, and we reversed that decision in
State v. Thomas,
No. 98-0152, unpublished slip op. (Wis. Ct. App. Dec. 9,1998),
aff'd,
¶3. On December 8, 1999, thе supreme court affirmed our decision.
See State v. Thomas,
*220 ¶ 4. While the 1997 petition was in the appeal process, another psychological examination of Thomas was conducted. Based on the psychologist's conclusions, the DOC changed its view and determined that the criteria for a Wis. Stat. ch. 980 commitment had been established. It wrote a December 9,1999 letter to the DOJ requesting that it file such a petition. The DOJ once again declined to do so in a December 22 letter to the Racine county district attorney. The district attorney responded by filing a second petition for ch. 980 commitment on December 28.
¶ 5. The next day, Thomas filed a motion to dismiss the second petition, arguing that the district attorney lacked authority to file it. At thе motion hearing, Thomas pointed out that his discharge date was December 25, 1999, and the second petition was filed on December 28. This is contrary, he contended, to the requirement in Wis. Stat. § 980.02(2)(ag) that the petition be filed within ninety days of release or disсharge. He further argued that the only reason he remained in custody beyond this date was that the Wis. Stat. ch. 980 petition, a civil matter, was in the appeal process; his criminal sentence, however, was completed. His motion was denied. Thomаs appeals.
¶ 6. A Wis. Stat. ch. 980 petition may be filed "within 90 days of discharge or release, on parole, extended supervision or otherwise, from a sentence that was imposed for a conviction for a sexually violent offense, from a sеcured correctional facility." Wis. Stat. § 980.02(2)(ag). The parties disagree about whether the December 28, 1999 petition filed against Thomas was timely filed. On the one hand, Thomas contends that § 980.02(2)(ag) requires that the petition be filed within ninety days of his discharge. Beсause his dis *221 charge date, 2 December 25, had passed, there was no authority to file the petition and it should be dismissed, he argues. The State, on the other hand, asserts that the time limit is not mandatory and that the term "otherwise" in § 980.02(2)(ag) is a catchall provision designed by the legislаture to cover instances such as this.
¶7. To resolve this dispute, we must examine WiS. Stat. § 980.02(2)(ag) and determine which party construes it correctly. This is a question of statutory interpretation, which we review without deference to the circuit court's conclusiоn.
See Grosse v. Protective Life Ins. Co.,
¶ 8. The State first argues that it did not lose authority to file a Wis. Stat. ch. 980 petition against Thomas because the time limit in Wis. Stat. § 980.02(2)(ag) is directory rather than mandatory. Section 980.02(2) prescribes:
A petition filed under this section shall allege that all of the following apply to the person alleged to be a sexually violent person:
*222 (ag) The person is within 90 days of discharge or release... from a sentence that was imposed for a conviction for a sexually violent offense .... (Emphasis added.)
¶ 9. The State contends that despite the "shall" directive in Wis. Stat. § 980.02(2), the time limit remains directory. "Although the use of the word 'shall' in a statute suggests that the provision is mandatory, this court has оften held that statutory time limits are directory despite the use of the word 'shall.'"
State v. R.R.E.,
¶ 10. In
R.R.E.,
the supreme court considered whether R.R.E. was entitled to release from his not guilty by reason of mental disease or defect commitment when the circuit court failed to conduct his reexamination hearing within the statutory thirty-day time limit.
See R.R.E.,
*223
¶ 11. The same policy consideration was an impetus for the crеation of WlS. STAT. ch. 980.
See State v. Carpenter,
¶ 12. The
Gerhardstein
court determined that thе statutory time limit in WlS. Stat. § 51.20(7)(c) (1981-82) was mandatory. In that case, the statute required that the circuit court, if it determines that probable cause exists, shall schedule a final commitment hearing within fourteen days of the person's involuntary commitment.
See Gerhardstein,
¶ 13. Our decision today is supported by the recent supreme court decision,
State v. Thiel,
¶ 14. The State alternatively argues that the term "otherwise" in Wis. Stat. § 980.02(2)(ag) refers to a generalized concept of custody, meaning that so long as Thomas was continuously detained, for whatever reason, the paragrаph applies. It relies on
State v. Keith,
¶ 15. The State insists that:
*225 Mr. Thomas at the time of the filing of the petitiоn was held in the custody of the Racine County Jail as a result of his sexual assault conviction, his ancillary chapter 980 proceeding, and finally Remittitur. This qualifies under the "otherwise" provision of the statute.
¶ 16. Although the lawfulness of Thomas's continued detention аfter his discharge date is not at issue here, the State argues that his continued detention equates with the "generalized concept of custody" approved by the court in
Keith. See id.
at 72. We disagree, finding the situation
in Keith
factually dissimilar. Keith served consecutive sentences of incarceration; Thomas did not. The authority to keep Thomas in jail beyond his discharge date is not found in WlS. STAT. ch. 980. He could not be criminally detained under ch. 980 because such persons are civil patients, not prisoners.
See Carpenter,
¶ 17. In sum, we conclude that Wis. Stat. § 980.02(2)(ag) is clear and unambiguous. It requires that a pеtition can only be filed within ninety days of a defendant's release or discharge from a criminal sentence for a sexually violent offense.
See Keith,
*226
¶ 18. We reached an analogous result in
State ex rel. Olson v. Litscher,
[T]here is no gray area in the statute — it is crystal clear. Our job is to apply the statute as it is written. Whether or not a place has been found for an inmate, he or she must be released on his оr her mandatory release date.
Id.
¶ 19. Unlike a mandatory release situation where an inmate's sentence technically continues while on parole, a discharge date signals the end of a criminal sentence. Once an inmate has reached his or her discharge date, the appropriate amount of time has been served and the inmate should be released from custody. The DOC's authority over that person has ceased. Just as we have held it to be unlawful to hold an inmate beyond mandatory release to find placement according to the requirements in WlS. Stat. § 301.45, we likewise hold that an inmate cannot be held beyond his or her discharge date while the State pursues a WlS. Stat. ch. 980 commitment. Wisconsin Stat. § 980.02(2)(ag) does not permit this.
By the Court. — Order reversed.
Notes
All references to the Wisconsin Statutes are to the 1997-98 version unless otherwise noted.
WISCONSIN Stat. § 980.02(2)(ag) refers to both release and discharge dates. One is entitled to mandatory release from prison on parole when two-thirds of his or her sentence is served. See Wis. Stat. § 302.11(1). After reaching his or her mandatory release date, one remains on parole until the maximum discharge date or the date on which the sentence would have been completed without the application of the mandatory release provision. See 73 Wis. Op. Att'y Gen. 81-82 (1984).
