Nassau Executive Laura Curran says she's suing the county Legislature over its unanimous decision to modify her proposed budget to include the reopening of a pair of police precincts, increased funding for NICE Bus service and changes to sales tax revenue projections.

Curran says the Legislature is mandated to provide notice to residents of its plans to amend the budget but failed to do so before the vote.

The Curran administration was dealt a setback Monday afternoon, when a Nassau Supreme Court judge denied a request for a temporary restraining order. That means the budget process will go on as scheduled. Even before the ruling, county lawmakers on both sides said it should not have come to a lawsuit, especially since they were going to vote in favor of the amendments anyway.

The governmental scuffle is unique in that the battle lines are drawn a bit differently this time -- it's not a fight between Democrats and Republicans, but rather between the county executive and a unified Legislature.

"By providing a lawsuit, it makes it look like the Legislature is not working together," says Legislator Kevan Abrahams. "I think 99 percent of the time we can talk this through."

Without the temporary restraining order, Curran has just four days to decide whether to veto the amended budget. A spokesperson for Curran expressed disappointment with the ruling but told News 12 that "we expect ultimately to prevail after the judge has considered all arguments."
