ALBANY — A federal judge yesterday ordered a halt to Gov. Paterson’s attempt to impose furloughs on about 100,000 state workers and to withhold negotiated raises.

US District Judge Lawrence Kahn had temporarily blocked the furloughs two weeks ago. His new preliminary injunction bars lawmakers from submitting or enacting short-term funding bills with those provisions.

The workers’ unions had argued that the cost-saving moves would change the terms of their contracts, in violation of the US Constitution.

One-day-a-week furloughs were part of an emergency spending bill approved by the Legislature, but the Senate passed a resolution criticizing the plan.

Raises have been withheld in several emergency bills used weekly to keep the state running until a budget is adopted. The budget was due April 1.
