Modifies provisions relating to minimum prison terms

HB 1506 establishes new minimum prison terms for Missouri felons committed to the Department of Corrections after August 28, 2025. For non-dangerous felonies without prior prison commitments, offenders must serve at least 50% of their sentence (with a 40% minimum). For non-dangerous felonies with prior prison commitments or dangerous felonies (as defined in state law), the minimum is 85% of the sentence (also with a 40% minimum). The bill also creates a Sentencing Advisory Commission to study and recommend changes to sentencing practices.
