GO plc has filed an application for a retrial following a judgement by the Court of Appeal on July 7 relating to former Cable and Wireless employees.
The court found that the employees were eligible for pension payments from the company.
The company is also seeking a suspension of the execution of the judgement pending the retrial application.
The company had said in August that the total cost for implementing the pension scheme in terms of the Court of Appeal judgment was expected to be in the region of €13.16 million.
