Gov. Andrew Cuomo told lawmakers on Thursday that they shouldn’t accept their first pay raise in two decades if they question the conditions attached by a salary commission.

Cuomo touched on the controversial pay deal that boosts lawmakers’ salaries for the first time in 20 years — and is now the subject of a lawsuit — on WAMC radio.

“I don’t see a rationale to say, ‘I’m taking the raise but I disagree with the commission’s report,'” Cuomo said. “You can’t have it both ways. If you don’t think it’s legal, don’t take the funds from an illegal act, right?”

The raises go into effect Jan. 1 when legislators’ base pay goes from $79,500 to $110,000. Salaries will be bumped up to $120,000 in 2020 and to $130,000 in 2021.

Top state officials will also see their paychecks increased.

Some lawmakers have blasted the raises because they come with conditions — limits on outside pay and an end to legislative stipends, known as “lulus.” The bump in pay also requires that the state budget be passed by the April 1 deadline.

Two weeks ago, conservative-based Government Justice Center filed a lawsuit challenging the legality of the Cuomo-appointed salary commission’s vote, saying only the legislature has the power to boost salaries, not an appointed panel.

On the radio, the governor defended the raise as long overdue.

“I have commissioners who can go out in the private sector … and earn 10 times as much. We need the raises to attract talent and because it’s hard to do raises for government employees politically,” he said.

“They haven’t been done in 17 years.”
