"Once a court classifies a defendant as a youthful offender, it is prohibited from imposing sanctions other than those of the Youthful Offender Act." Mendez v. State, 835 So.2d 348, 349 (Fla. 4th DCA 2003); State v. Arnette, 604 So.2d 482, 484 (Fla. 1992) ("[Y]outhful offenders maintain youthful offender status even when they violate a condition of community control."); State v. Watts, 558 So.2d 994, 997-98 (Fla. 1990) ("[O]nce the circuit court has given a defendant youthful offender status and has sentenced him as a youthful offender, it must continue that status and only resentence the defendant as a youthful offender for a violation of the probation or community control portion of his youthful offender sentence."); Gardner v. State, 656 So.2d 933 (Fla. 1st DCA 1995); Young v. State, 654 So.2d 1206 (Fla. 5th DCA 1995). Youthful offender status may be revoked when the defendant is charged and convicted with a new, substantive offense.
Since Dunbar's probation was revoked for technical violations, he can only be sentenced to a total of six years. State v. Arnette, 604 So.2d 482 (Fla. 1992); Young v. State, 654 So.2d 1206 (Fla. 5th DCA 1995); Darden v. State, 641 So.2d 431 (Fla. 2d DCA 1994). A youthful offender can be sentenced in excess of six years after revocation of probation if the violation was substantive. See § 958.14, Fla. Stat. (1993); Reeves v. State, 605 So.2d 562 (Fla. 2d DCA 1992).
