Pratt & Whitney said Tuesday a federal appeals court granted the jet engine maker's request for an expedited appeal of a lawsuit it lost as it tries to move 1,000 jobs out of Connecticut.

The subsidiary of United Technologies Corp. filed five proposed issues in its appeal to the 2nd U.S. Circuit Court of Appeals of a Feb. 5 decision halting its plans to move engine repair jobs to Columbus, Ga., Japan and Singapore.

U.S. District Court Judge Janet C. Hall in Bridgeport ruled in favor of the Machinists union, which sued Pratt & Whitney to halt efforts to shift the jobs. The union said the company violated its contract with the union that requires it to make every effort to preserve jobs in Connecticut.

Among the issues Pratt & Whitney said it may raise is its contention that Hall was wrong in how she interpreted the definition of "every reasonable effort" to preserve jobs. Pratt & Whitney said it is not required to save jobs if it results in lower profit.

The company also said Hall substituted her own judgment for Pratt & Whitney's business judgment in how it measures profit and financial performance.

In a request filed last week, Pratt & Whitney said a decision is needed soon to avoid financial harm because the company plans to shut two Connecticut plants immediately after its union contract expires in December.

The court said the two parties may file legal papers in April and May and an appeal may be heard as early as the week of May 31.

A lawyer for the union would not immediately comment. The union's chief negotiator did not immediately return a call seeking comment.
