Arizona has asked an appeals court to reconsider its ruling that concluded about 33,000 inmates could join a lawsuit protesting the quality of health care in the state's prisons.
A three-judge panel of 9th Circuit Court of Appeals in early June had rejected an appeal by officials who argued the inmates didn't have enough in common to merit class-action status.
The state asked an 11-judge panel to reconsider this ruling.
The state's attorneys questioned whether class-action rules were satisfied simply because the inmates are confined at the same prison and make the same type of liability claim.
The inmates' lawyers say in records filed Tuesday that all prisoners are at risk if their care is deficient, not just those who are currently sick.
