Disgraced ex-Senate Majority Leader Dean Skelos has put in his retirement papers, which could fetch him up to $95,000 a year in state pension benefits.

The convicted felon immediately forfeited his Long Island Senate seat on Dec. 11 when he and his son Adam Skelos were found guilty on federal corruption charges. Eleven days later, on Dec. 22, he filed for his pension, according to the state comptroller’s office.

Skelos isn’t the only crooked politician trying to cash in on a “public service” career based on lies. Ex-Assembly Speaker Sheldon Silver — also convicted recently on corruption charges — filed for retirement benefits just one day after the ruling in his case.

Silver would be eligible for about $90,000, but both former lawmakers run the risk of having the money seized under “claw-back” provisions by the US Attorney Preet Bharara.

Good government groups argue that should be a moot point, that a conviction should immediately render one’s pension subject to forfeiture.

“It’s outrageous that state lawmakers can continue to collect their pensions when they’ve violated the public trust,” said Dick Dadey, director of the Citizens’ Union. “It needs to be changed. It really diminishes trust in our government. The penalty of pension forfeiture should at the very least be left to the discretion of the judges.”

Skelos is vested in the state’s most generous “tier one” pension system after working government jobs for nearly 45 years.

Before his election to the Assembly in 1980 and later the Senate, he worked as a clerk to Nassau County judge and later a staffer to the Assembly in the 1970s.

Bharara has said it “doesn’t seem at all fair” that Silver and Skelos will cash in on pensions and is threatening to go after them to satisfy any forfeiture judgments.

“We will be looking at all the ways we can make sure that justice is done,” Bharara said in a recent radio interview.
