Umm, that's an interesting garbling of the facts, however even when in order, it's a serious mess:

Justices, 5-4, Tell California to Cut Prisoner Population (NY Times)

"Conditions in California's overcrowded prisons are so bad that they violate the Eighth Amendment's ban on cruel and unusual punishment, the Supreme Court ruled on Monday, ordering the state to reduce its prison population by more than 30,000 inmates."

The toilet issue apparently does exist somewhere, among many other appalling conditions. Of course, conditions are not uniformly that extreme, but in total, bad enough to result in this decision.

"State officials in California will have two years to comply with the order, and they may ask for more time. Justice Kennedy emphasized that the reduction in population need not be achieved solely by releasing prisoners early. Among the other possibilities, he said, are new construction, transfers out of state [which has already been done] and using county facilities. "
