Section 16-56 Duration of probation; revocation.

    (a) A term of probation commences on the day it is imposed. Multiple terms of probation, whether imposed at the same time or at different times, shall run concurrently. Terms of probation shall also run concurrently with any federal or other state jail, prison, probation or parole term for another offense to which the defendant is or becomes subject during the period, unless otherwise specified by the court.

    (b) The court may terminate a period of probation and discharge the defendant at any time before completion of the specific term fixed under section 16-52 if warranted by the conduct of the defendant and the ends of justice. Procedures for termination and discharge may be established by rule of court.

    (c) If the defendant violates a condition of probation at any time prior to the expiration or termination of the probation term, the court may continue him on the existing conditions, with or without modifying or enlarging the conditions, or, if such continuation, modification, or enlargement is not appropriate, may revoke probation and order that any sentence previously imposed be executed. If imposition of sentence was suspended, the court may revoke probation and impose any sentence available under section 16-83. The court may mitigate any sentence of imprisonment by reducing the prison or jail term by all or part of the time the defendant was on probation.
    (d) Probation shall not be revoked without giving the probationer notice and an opportunity to be heard on the issues of whether he violated a condition of probation and, if he did, whether revocation is warranted under all the circumstances.

    (e) At any time during the term of probation the court may issue a notice to the probationer to appear to answer a charge of a violation, and the court may issue a warrant of arrest for the violation. Such notice shall be personally served upon the probationer. The warrant shall authorize the return of the probationer to the custody of the court or to any suitable detention facility designated by the court.

    (f) Any probation officer, if he has probable cause to believe that the probationer has violated a condition of probation, may arrest the probationer without a warrant, or may deputize any other officer with the power of arrest to do so by giving him a written statement of the circumstances of the alleged violation, including a statement that the probationer has, in the judgment of the probation officer, violated the conditions of his probation. The written statement, delivered with the probationer to the official in charge of any jail or other detention facility, shall be sufficient authority for detaining the probationer pending a preliminary hearing on the alleged violation.

    (g) If the probationer is arrested under the authority granted in paragraphs (e) and (f) of this section, he shall have the right to a preliminary hearing on the violation charged. He shall be notified immediately in writing of the alleged probation violation. If he is arrested in the jurisdiction of the sentencing court, and the court which placed him on probation is immediately available, the preliminary hearing shall be heard by the sentencing court. Such preliminary hearings shall be conducted as provided by rule of court. If it appears that there is probable cause to believe that the probationer has violated a condition of his probation, or if the probationer waives the preliminary hearing, the judge shall order the probationer held for further proceedings in the sentencing court. If probable cause is not found, this shall not bar the sentencing court from holding a hearing on the question of the probationer's alleged violation of a condition of probation nor from ordering the probationer to be present at such a hearing. Provisions regarding release on bail of persons charged with offenses shall be applicable to probationers arrested and ordered held under this provision.

    (h) Upon such arrest and detention, the probation officer shall immediately notify the sentencing court and shall submit to the court a written report showing in what manner the probationer has violated the conditions of probation. Thereupon, or upon arrest by warrant, the court shall cause the probationer to be brought before it without unnecessary delay for a hearing on the violation charged. Revocation hearings shall be conducted as provided by rule of court.

    (i) The power of the court to revoke probation shall extend for the duration of the term of probation designated by the court and for any further period which is reasonably necessary for the adjudication of matters arising before its expiration, provided that some affirmative manifestation of an intent to conduct a revocation hearing occurs prior to the expiration of the period and that every reasonable effort is made to notify the probationer and to conduct the hearing prior to the expiration of the period.
