§ 9771. Modification or revocation of order of probation
(a) General rule.--The court may at any time terminate continued supervision or lessen or increase the conditions upon which an order of probation has been imposed.
(b) Revocation.--The court may revoke an order of probation upon proof of the violation of specified conditions of the probation. Upon revocation the sentencing alternatives available to the court shall be the same as were available at the time of initial sentencing, due consideration being given to the time spent serving the order of probation.
(c) Limitation on sentence of total confinement.--The court shall not impose a sentence of total confinement upon revocation unless it finds that:
(1) the defendant has been convicted of another crime; or
(2) the conduct of the defendant indicates that it is likely that he will commit another crime if he is not imprisoned; or
(3) such a sentence is essential to vindicate the authority of the court.
(d) Hearing required.--There shall be no revocation or increase of conditions of sentence under this section except after a hearing at which the court shall consider the record of the sentencing proceeding together with evidence of the conduct of the defendant while on probation. Probation may be eliminated or the term decreased without a hearing.
