The New York Court of Appeals has pared down claims brought by the state Attorney General’s Office in its $11 billion suit against Credit Suisse, which it accused of misleading investors about the risks of purchasing residential mortgage-backed securities in the lead up to the 2008 financial crisis.

A split court of appeals ruled that the AG’s claims under the state’s Martin Act were time-barred by a three-year statute of limitations, refuting arguments by the AG’s Office and rulings by two lower courts that there was a six-year window to bring the claims.
