California Proposition 57, passed in November 2016, aimed to reform the state's criminal justice system. It focused on increasing parole opportunities for non-violent offenders and allowing judges, rather than prosecutors, to decide whether juveniles should be tried as adults. The proposition sought to reduce overcrowding in prisons and promote rehabilitation. Additionally, Proposition 57 included provisions for good behavior credits, enabling inmates to earn time off their sentences for participating in educational and rehabilitative programs. This initiative was part of a broader effort to address issues related to mass incarceration and improve public safety in California.
