Courts have jurisdiction to correct an illegal sentence at any time.
The issue of whether a criminal sentence is illegal is a question of law. Interpretation of a statute is a question of law. An appellate court's review of a question of law is unlimited. The general rule is that a criminal statute must be strictly construed in favor of the accused. The rule of strict construction, however, is subordinate to the rule that judicial interpretation must be reasonable and sensible to effect legislative design and intent.
