IL SB3400

Amends Criminal Code to establish sentencing guidelines for individuals found guilty under accountability theory (aiding, abetting, or soliciting another to commit a crime) when they did not personally commit the criminal act and it was not done at their express direction.

First degree murder: maximum 30 years imprisonment (determinate) or 50 years (extended term); Class X felony: maximum 15 years (determinate) or 30 years (extended term); Class 1 felony: maximum 7 years or 10 years for second degree murder (determinate) or 15 years (extended term).

Class 2 felony: maximum 3 years imprisonment (determinate) or 7 years (extended term); Class 3 felony: maximum 2 years (determinate) or 5 years (extended term); other felonies treated as Class A misdemeanor.

Prohibits separate sentences when another person's conduct satisfied an element of the offense; establishes parole/supervised release terms ranging from 6 months to 2 years depending on felony class.

Prohibits probation or conditional discharge for first degree murder convictions; restricts periodic imprisonment options and impact incarceration programs; applies provisions for fines, restitution, concurrent/consecutive sentencing, and good behavior credits.
