This lawsuit could still be followed by several more before May 9th, the official end to the 60-day period surrounding the "official" notification "window retirees" received.
P.S. A copy of the petition is posted on the OPRI website for those interested in reading it. The OPRI site also has exerpted section 14b of the statute enacted by the legislature in 2003 to highlight the area of law addressed by this suit. The Robinson case basically asks the Court to order PERS to charge the expenses of the retirees off to administrative expenses as the court already ruled that the COLA freeze was an improper way to recover the money.
