"We have reviewed the court's opinion and determined that an appeal would not be warranted," Attorney General Andrew Cuomo's spokesman Alex Detrick said. "Thus, for all intents and purposes, the Grasso case is over."

Cuomo's announcement came soon after the Appellate Division of State Supreme Court ruled the attorney general's authority to pursue two remaining claims against Grasso lapsed when the New York Stock Exchange changed in 2005 from a nonprofit to a for-profit corporation. Last week, the Court of Appeals, New York's highest court, dismissed four common law claims against the 2003 compensation package.

The midlevel court concluded Tuesday that seeking to recover money for two remaining claims under New York's Not-For-Profit Corporation Law would simply benefit the NYSE's private owners. The court also dismissed a claim against Home Depot founder Kenneth Langone, who was chairman of the exchange's compensation committee and was accused of misleading other NYSE board members about Grasso's pay.

Justice James McGuire wrote that based on case law and the "evident purpose" of the not-for-profit law, the attorney general's authority to pursue the claims "lapsed" when the NYSE became a for-profit corporation. He wrote for the court majority.
