Pennsylvania-based information-technology company Unisys Corp. can't enforce an agreement to compel arbitration in an age-discrimination suit brought by former employees who were fired by the company before they signed an employment agreement that had an arbitration clause with an outsourcing company, a federal judge has ruled.

U.S. District Judge Anita Brody of the Eastern District of Pennsylvania, however, will allow Unisys to file a new motion to compel arbitration under a summary judgment standard that would allow for limited discovery on the plaintiffs' second claim, bringing age-discrimination allegations regarding the second termination of their employment at the request of Unisys, which contracted with the outsourcing company called Hexaware.
