Credit for Time Spent In Custody Pursuant to a Detainer Warrant to a Parole Violator

In Gaito v. Pennsylvania Board of Probation and Parole, 488 Pa. 397, 412 A.2d 568 (1980), the Supreme Court held that "time spent in custody pursuant to a detainer warrant shall be credited to a convicted parole violator's original term ... only when the parolee was eligible for and had satisfied bail requirements for the new offense and thus remained incarcerated only by reason of the detainer warrant lodged against him." Gaito, 488 Pa. at 403, 412 A.2d at 571. If, on the other hand, "a parolee is not convicted, or if no new sentence is imposed for that conviction on the new charge, the pre-trial custody time must be applied to the parolee's original sentence." Gaito, 488 Pa. at 404, 412 A.2d at 571 n.6. In the cases following Gaito, this Court held that once a parolee is sentenced on a new criminal offense, the period of time between arrest and sentencing, when bail is not posted, must be applied toward the new sentence and not to the original sentence. See, e.g., Davidson v. Pennsylvania Board of Probation and Parole, 722 A.2d 232 (Pa. Cmwlth. 1998).
