Multi-state lottery groups pushed back on Monday against a move by lottery winners in Illinois to drag dozens of states into a lawsuit against the Illinois Lottery’s suspension of payments. A class action originally filed in September in U.S. District Court in Chicago seeking to force the Illinois Lottery to pay winners was amended last week to add as defendants lottery agencies in 43 states, Washington, D.C., the U.S. Virgin Islands and Puerto Rico that participate in the Mega Millions and Powerball multi-state lotteries.
