Convicted South Florida Ponzi schemer and former law firm chairman Scott Rothstein is stuck with his 50-year prison sentence after the government said he violated the terms of his plea agreement.

The U.S. Attorney's Office asked Tuesday to withdraw its motion to reduce Rothstein's sentence, filed in 2011 as a placeholder in case the ex-attorney who ran a $1.2 billion scheme qualified for a sentence reduction for cooperating with the government.

“In the judgment of the United States, the defendant provided false material information to the government and violated the terms of his plea agreement,” Assistant U.S. Attorney Lawrence LaVecchio wrote in the motion to withdraw. “Therefore, in the exercise of its sole discretion, the government moves to withdraw the previously filed motion.”
