More than 40 000 prisoners could be released from California prisons in the coming months. Not because of an amnesty, or the expiration of their sentence and procedural situation, but thanks to a ruling by the Supreme Court of the United States. The nine judges of the Court - a majority, 5 against, 4 - have determined that the living conditions in overcrowded and unsanitary prisons are "incompatible with the concept of human dignity." Hence the order to empty them.
