(Reuters) - The New Jersey Supreme Court ruled on Thursday that the state's 2011 public pension reform did not improperly freeze retirees' cost-of-living increases in a case that could have cost the state billions of dollars.
Governor Chris Christie's administration suspended the so-called COLA payments, which are tied to inflation, as part of bipartisan reforms aimed at curtailing the ballooning cost of public pensions.
