Convicted former House speaker Salvatore F. DiMasi and codefendant Richard W. McDonough are seeking a review of their case by the US Supreme Court, their lawyers said Monday.
The two have filed petitions for a writ of certiorari, requests for the court to take up their case, said Thomas R. Kiley and Martin Weinberg, the lawyers for DiMasi and McDonough, respectively.
In August, a federal appeals court in Boston rejected appeals by DiMasi and McDonough, saying they had raised a “panoply of arguments” that were “myriad and complex,” but the court could find no flaws in the actions of a lower court judge.
DiMasi and McDonough, a lobbyist who was his friend, were convicted after a 2011 trial. They were found guilty of honest services fraud in a kickback scheme to funnel $65,000 to DiMasi in exchange for his help securing contracts for a Burlington software company, Cognos. DiMasi was also convicted of extortion.
A third man, DiMasi financial adviser Richard Vitale, was acquitted. A fourth man, former Cognos salesman Joseph P. Lally Jr., pleaded guilty in a plea deal.
DiMasi, 68, is battling cancer and being held at a prison in North Carolina. He is scheduled to be released in November 2018, the Federal Bureau of Prisons website says.
