        resulted in such term of supervised release without credit for 
        time previously served on postrelease supervision, if the 
        court, pursuant to the Federal Rules of Criminal Procedure 
        applicable to revocation of probation or supervised release, 
        finds by a preponderance of the evidence that the defendant 
        violated a condition of supervised release, except that a 
        defendant whose term is revoked under this paragraph may not be

        condition set forth in subsection (d);
            ``(2) possesses a firearm, as such term is defined in 
        section 921 of this title, in violation of Federal law, or 
        otherwise violates a condition of supervised release 
        prohibiting the defendant from possessing a firearm; or
            ``(3) refuses to comply with drug testing imposed as a 
        condition of supervised release;
the court shall revoke the term of supervised release and require the 
defendant to serve a term of imprisonment not to exceed the maximum 
term of imprisonment authorized under subsection (e)(3).
    ``(h) Supervised Release Following Revocation.--When a term of 
supervised release is revoked and the defendant is required to serve a 
term of imprisonment that is less than the maximum term of imprisonment 
authorized under subsection (e)(3), the court may include a requirement 
that the defendant be placed on a term of supervised release after 
imprisonment. The length of such a term of supervised release shall not 
exceed the term of supervised release authorized by statute for the 
offense that resulted in the original term of supervised release, less 
any term of imprisonment that was imposed upon revocation of supervised 
release.
    ``(i) Delayed Revocation.--The power of the court to revoke a term 
of supervised release for violation of a condition of supervised 
release, and to order the defendant to serve a term of imprisonment 
and, subject to the limitations in subsection (h), a further term of 
supervised release, extends beyond the expiration of the term of 
supervised release for any period reasonably necessary for the 
adjudication of matters arising before its expiration if, before its 
expiration, a warrant or summons has been issued on the basis of an 
allegation of such a violation.''.

Summary: Amends the Federal criminal code to allow the court, in determining the sentence to be imposed in the case of a violation of probation or supervised release, to consider guidelines or policy statements issued by the US Sentencing Commission. Revises provisions regarding the revocation of probation to: (1) authorize the court to resentence a defendant who violates a condition of probation at any time prior to the expiration or termination of the term of probation. And (2) provide for mandatory revocation for possession of a controlled substance or firearm or refusal to comply with drug testing imposed as a condition of probation and resentencing of the defendant to a sentence that includes a term of imprisonment. Directs the court to revoke supervised release and require the defendant to serve in prison all or part of the term of supervised release authorized by statute for the offense that resulted in such term of release without credit for time previously served on post-release supervision if the court finds that the defendant violated a condition of supervised release, with exceptions. Provides for mandatory revocation of supervised release for possession of a controlled substance or firearm or refusal to comply with drug testing imposed as a condition of supervised release. Authorizes the court to include a requirement that the defendant be placed on supervised release after imprisonment when a term of supervised release is revoked and the defendant is required to serve a term of imprisonment less than the maximum authorized. Specifies that the length of such a term of supervised release shall not exceed that authorized by statute for the offense that resulted in the original term of release, minus any term of imprisonment that was imposed upon revocation of supervised release.
