BOSTON >> Imprisoned former Massachusetts House Speaker Salvatore DiMasi is asking the state's highest court to restore more than $127,000 in pension payments he says were "wrongfully withheld" from his family.

The 70-year-old DiMasi is serving an eight-year federal prison sentence following his conviction in 2011 on corruption charges.

Prosecutors said the Democrat used his political clout to steer state contracts to a software company in exchange for payments totaling $65,000. The state retirement board revoked his nearly $5,000 monthly pension after his conviction.

But his lawyer, Thomas Kiley, tells the Boston Herald he will argue that DiMasi's conviction did not become final until January 2014, when the U.S. Supreme Court refused to consider his appeal.

The hearing before the Supreme Judicial Court is scheduled for Feb. 9.
