The lawsuit against the former James Square Health and Rehabilitation Centre has been given class action status by State Supreme Court Justice Anthony Paris.
The motion was approved Wednesday in a Syracuse courtroom.
The status means the approximately 1,000 people who lived in the facility from Aug. 25, 2014 to present will be invited to be plaintiffs in the case.
Later this year, each person will be mailed a letter with the offer to take part in the lawsuit. Each person can choose to opt out, if they feel an individual suit will produce better results.
The people will be represented by Finkelstein, Blankinship, Frei-Pearson & Garber, LLP, the same group who filed the suit, at first with two plaintiffs.
This decision is separate from the settlement reached Tuesday between Clinton Square Operations, the current owners of the now-renamed Bishop Rehabilitation and Nursing Center.
Clinton Square Operations was one defendant in the case, but if the settlement is approved by the justice, litigation will continue against only previous owners, who have not settled.
