The state can still pursue its appeal — and the administration vowed to do so. But the court's 6-3 vote was a disappointment for Brown, who had launched a political crusade against a three-judge panel that has consistently ruled that overcrowded prison conditions violate the rights of inmates.
Brown's lawyers told the justices that the state has improved the treatment of inmates, easing crowding by keeping tens of thousands of prisoners in county custody and spending hundreds of millions of dollars to improve the quality of prison healthcare.
The panel's demands, Brown has argued repeatedly, create a serious public safety threat. The state had asked the high court to put the panel's order on hold while an appeal goes forward.
