Suspended imposition of sentence or SIS is a sentencing option available to the trial court. In SIS, usually the defendant is placed on probation. If the defendant violates probation and faces revocation, the Judge may order any sentence within the full range of punishment for the crime convicted. If the defendant successfully completes probation, no sentence is actually ordered. Therefore normally an SIS is not considered a ‘conviction’ for anything other than law enforcement purposes.

In Missouri, Mo. Rev. Stat. § 557.011.2 allows a court to Suspend the imposition of sentence, with or without placing the person on probation. Suspended executions of sentence are considered to be final judgments by Missouri courts, while suspended impositions of sentence are not. However both suspended impositions of sentence and suspended executions of sentence qualify as prior convictions for purposes of 21 U.S.C.S. § 841(b)(1)(A).( Drug Offenses)[ United States v.
