BC's largest public sector union has successfully appealed a multi million dollar fine levied by Elections BC.

 The BC Government and Service Employees' Union won't have to pay $3.2 million for ads it ran during two recent byelection campaigns.

 Elections BC claimed the union overspent advertising limits by hundreds of thousands of dollars during those campaigns.

 Chris Bradshaw with the BCGEU says the court's decision is a relief.

 "We're happy that the court has agreed with us and agreed to lift the penalties."

 As a result of its appeal the union will be able to run advertisements for next may's provincial election after initially facing the threat of deregistration.
