revise and repeal provisions related to rape offenses and to increase the penalty therefor.

HB 1031 revises South Dakota's rape offense definitions and increases penalties, primarily affecting victims under 13 and perpetrators convicted of sexual crimes against minors. It adds new circumstances to rape definitions (e.g., victim incapacity due to intoxication) and establishes a 15-year minimum sentence for first offenses involving victims under 13. The bill also removes the statute of limitations for rape cases involving victims under 13 or using force/coercion, allowing charges to be filed until the victim turns 25. These changes directly impact criminal sentencing for sexual offenses and extend legal accountability for certain victims.
