On April 4, 2011, the Public Safety Realignment Act (AB 109) was signed into law by Governor Jerry Brown. The policy changes in the Act focus on alleviating overcrowding in the California State prisons and reducing the state corrections budget. This is achieved largely through transferring responsibility for incarceration and supervision of many low level inmates and parolees from the California Department of Corrections and Rehabilitation (CDCR) to the county level. AB 109 went into effect October 1, 2011.
