In Pennsylvania, an indeterminate sentencing scheme is employed wherein a sentencing judge announces a range consisting of a minimum and maximum sentence and only by serving time may an inmate attain parole, if proper, at the end of his minimum sentence. Unlike its federal counterpart, the only statute in Pennsylvania governing the award of credit for time served by an inmate after his state sentence is imposed is Section 9761 of the Judicial Code, 42 Pa. C.S. 9761, and there is no mention in this statute regarding the applicability of "good time" credit earned elsewhere to a Pennsylvania sentence. Section 9761 of the Judicial Code provides: (b) SENTENCES IMPOSED BY OTHER SOVEREIGNS.-- If the defendant is at the time of sentencing subject to imprisonment under the authority of any other sovereign, the court may indicate that imprisonment under such other authority shall satisfy or be credited against both the minimum and maximum time imposed under the court's sentence. If the defendant is released by such other authority before the expiration of the minimum time imposed by the court, he shall be returned to a correctional institution of the Commonwealth to serve the time which remains of the sentence. If the defendant is released after the minimum time has elapsed, he shall be considered for parole on the same basis as a prisoner who has served his minimum time in a correctional institution of the Commonwealth. If the defendant is released after the maximum time imposed under the sentence of imprisonment he shall be deemed to have served his sentence.
