In US v. Joseph Dees, No 05-4949 (Nov. 8, 2006), the Circuit joined with six other circuits in ruling that under 18 usc sect 3584(a), a district court may "impose consecutive terms of imprisonment upon revocation of supervised release -- even when the sentences for the underlying crimes ran concurrently."
Dees had pleaded guilty on three separate dates to three separate offenses. He was sentenced, however, for all 3 cases at the same time by one judge. The sentence was 51 months in prison and 3 years supervised release on each of three separate convictions to run concurrently. Dees served his sentence and upon release accumulated multiple violations of his release conditions. At a violation hearing, the judge revoked supervised release and imposed 24 months in prison on each of the three supervised release terms, to run consecutively, for a total of 72 months. The Circuit found that nothing in the statute precludes such consecutive sentences upon violation, even though the original terms of supervised release ran concurrently.
