2001 Federal Sentencing Guideline Manual
Prior to the implementation of the federal sentencing guidelines, a court could stay the imposition or execution of sentence and place a defendant on probation. When a court found that a defendant violated a condition of probation, the court could continue probation, with or without extending the term or modifying the conditions, or revoke probation and either impose the term of imprisonment previously stayed, or, where no term of imprisonment had originally been imposed, impose any term of imprisonment that was available at the initial sentencing.
The statutory authority to "suspend" the imposition or execution of sentence in order to impose a term of probation was abolished upon implementation of the sentencing guidelines. Instead, the Sentencing Reform Act recognized probation as a sentence in itself. 18 U.S.C. § 3561. Under current law, if the court finds that a defendant violated a condition of probation, the court may continue probation, with or without extending the term or modifying the conditions, or revoke probation and impose any other sentence that initially could have been imposed. 18 U.S.C. § 3565. For certain violations, revocation is required by statute.
(b) Supervised Release.
Supervised release, a new form of post-imprisonment supervision created by the Sentencing Reform Act, accompanied implementation of the guidelines. A term of supervised release may be imposed by the court as a part of the sentence of imprisonment at the time of initial sentencing. 18 U.S.C. § 3583(a). Unlike parole, a term of supervised release does not replace a portion of the sentence of imprisonment, but rather is an order of supervision in addition to any term of imprisonment imposed by the court. Accordingly, supervised release is more analogous to the additional "special parole term" previously authorized for certain drug offenses.
With the exception of intermittent confinement, which is available only for a sentence of probation, the conditions of supervised release authorized by statute are the same as those for a sentence of probation. When the court finds that the defendant violated a condition of supervised release, it may continue the defendant on supervised release, with or without extending the term or modifying the conditions, or revoke supervised release and impose a term of imprisonment. The periods of imprisonment authorized by statute for a violation of the conditions of supervised release generally are more limited, however, than those available for a violation of the conditions of probation. 18 U.S.C. § 3583(e)(3).
