PROVIDENCE, R.I. — Frank E. Corrente, a former city employee convicted in the “Operation Plunder Dome” case, is entitled to pension benefits from his first time working in City Hall, the state’s Supreme Court found.

In a ruling issued Friday afternoon Chief Justice Paul Suttell affirming three Corrente-related decisions from the state’s Superior Court.

Corrente will now be able to collect his monthly pension of $1,852.61 based on his first City Hall salary.

The decision closes the book on more than 20 years of pricey court battles. Since the city became involved in the case in 2008 it spent $233,610 in legal fees, according to a summary of costs obtained by The Providence Journal through a Access to Public Records Act request.

Corrente, 88, worked as Mayor Vincent “Buddy” Cianci Jr.’s director of administration in the 1990s. He stayed in that job for almost 10 years and when he retired in 1999, he received a monthly pension benefit of $5,881.30 based on a gross salary of $91,656.58, according to court documents.

In 2002, he was convicted on racketeering and corruption charges that muddled his right to that money. A jury found that Corrente, recently featured in the hit podcast “Crimetown,” took payoffs while working for Cianci from a business man working undercover for the FBI.

But before joining Cianci’s City Hall team, Corrente worked as a financial specialist in the controller’s office starting in June 1967. He was promoted to the city controller position in 1981, and retired in April 1987. At that time he was awarded a monthly pension of $1,852.61 based on a gross salary of $42,098.45.

Justices ruled on three issues Friday:

— They denied an appeal from Corrente who wanted, at minimum, a tax credit for the money he already paid to the government for the pension that was revoked. Corrente is being represented by John B. Harwood, former speaker of the Rhode Island House of Representatives.

— In the same vein, justices upheld a decision by the Retirement Board, represented by Raymond A. Marcaccio, who argued that Corrente should not receive the credit because there is no evidence that any taxes were taken from his pension payments from 1999 to 2002.

— The justices denied a cross appeal from Mayor Jorge Elorza and the city, represented by John D. Plummer. Plummer argued Corrente was not entitled to either pension and had requested a new Superior Court trial.
