SPRINGFIELD (AP) — Illinois Gov. Pat Quinn's plan to save money by closing seven correctional facilities was halted again Wednesday when a southern Illinois judge ordered the Democrat to negotiate terms with a union representing prison workers.

Associate Circuit Judge Charles Cavaness issued the ruling from Alexander County in far southern Illinois. It's home to the central point of the dustup, the high-security Tamms prison Quinn wants shuttered.

The preliminary injunction sought by the American Federation of State, County, and Municipal Employees would continue holding up closure of the Tamms "supermax" prison, where gang leaders and extraordinarily violent inmates are housed, the women's prison at Dwight, three halfway houses and two juvenile detention centers. It also bars any employee layoffs.
