The Justus decision made it clear that the COLA increase could be altered by the legislature, I'm curious , what language in that decision makes you think that the court would allow a retroactive benefit cut for the years prior to their decision on the contractual status of the COLA?  I would assume any such action by the state legislature would be challenged in court, perhaps all the way to the SC this time not mention the negative response from some 400,000 +PERA members. Possible but doesn't seem probable.
