Gov. Andrew Cuomo shot back at Assembly Speaker Carl Heastie on Wednesday in what has become a nasty dispute over legislative pay raises, saying the law that created a salary commission also allowed it to examine other issues such as limiting outside income.

Heastie claims the commission exceeded its authority when it attached conditions to the pay hikes.

“Everybody should just read the law. … the law is clear. What we agreed to was in the law. Read the law on the pay commission,” Cuomo said on WAMC radio.

“The law, for example, says the phase-in of any pay raise would be linked to ‘timely legislative passage of the budget for the preceding year.’”

He said it also allowed an examination of “non-salary benefits.”

Cuomo suggested there are some legislators who would forgo a 64 percent pay hike, from $79,500 to $130,000 in 2021, if it means keeping lucrative outside income and leadership stipends.

The salary commission recommended limiting outside income to 15 percent of a legislator’s new salary, an end to most leadership stipends and conditioning a three-year phase-in of the salary hike on condition that the state budget is passed by the April 1 deadline.

If lawmakers miss the deadline, the second or third year of the hikes would be nullified.

Cuomo said Heastie and Senate GOP leader John Flanagan, who also criticized the commission, “are playing into the hands of a lawsuit” aimed at overturning its actions.

The dispute between Cuomo and Heastie is particularly noteworthy. Heastie leads the Assembly, which has a 2-1 Democratic majority, and the governor needs their support to pass his ambitious 20-point agenda in 2019.

Heastie on Tuesday claimed Cuomo was lying about the deal he made before appointing the commission.

“I’ll continue to say, when we negotiated the bill, myself and Senator [John] Flanagan, even the governor, we agreed — I don’t care what the governor says publicly — the three of us agreed that the commission’s purview wasn’t really stipends and it wasn’t really outside income,” Heastie said at the time.

“But that was the result. And now the courts will figure it out,” he said, referring to a lawsuit that claims only lawmakers, not a commission, can approve legislative pay increases.

Heastie also charged that the recommendation that ties pay raises to an on-time budget gives Cuomo an unfair advantage during negotiations.

“So now the governor can load up everything he wants” in the budget and if the lawmakers try to challenge him, they’re denied a pay hike, Heastie said.
