Former state Assembly Speaker Sheldon Silver's 2015 conviction on corruption charges was tossed out by a federal appeals court Thursday morning, and the U.S. Attorney for the Southern District of New York quickly announced that his office would retry the case.

A panel of the U.S. Court of Appeals for the Second Circuit ruled that the evidence presented in Silver's high-profile prosecution was sufficient to convict him of money laundering, Hobbs Act extortion and honest services fraud.

However, citing a U.S. Supreme Court decision involving former Virginia Gov. Bob McDonnell, a Republican, McDonnell v. United States, 15-474, which narrowed the definition of bribery, the panel said Southern District Judge Valerie Caproni erred by not properly instructing the jury on the charges of honest services fraud and extortion.
