What is AB109 probation?

Select defendants are able to serve their entire sentence in local prison (aka jail) under AB 109. Upon release they'll have no supervision. For example, on a 16 month AB 109 sentence, the court has the option of splitting the time in custody and the time of PRCS (post-release community supervision). Because, after good time credits, the actual time in custody is only eight months on a regular, non-split sentence, many people opt to do simply do the time. Under these circumstances, there is no supervision. If you do have a sentence where some time on PRCS remains, the max that you can do is 180 days on a violation unless you pick up a new case. You cannot ever get real prison, just time in the local jail.
