FORT LAUDERDALE, Fla. — The former Florida lawyer convicted of orchestrating a $1.2 billion Ponzi scheme likely won’t be getting out of prison early after prosecutors sought to withdraw an offer to cut his sentence.

Court documents filed Tuesday show that prosecutors have concluded that Scott Rothstein failed to comply with terms of his plea agreement by providing false information to the government. Rothstein had promised to fully cooperate in a lengthy probe that sent more than two dozen people to prison.

Rothstein is serving a 50-year prison term after pleading guilty in 2010 to running a massive fraud scheme revolved around investments in phony court settlements. Rothstein’s former Fort Lauderdale law firm went out of business.

Rothstein’s lawyer objects to withdrawal of the sentence reduction, which awaits a ruling by a federal judge.
