Konkola Copper Mines (KCM) has challenged a decision by Copperbelt Energy Corporation (CEC) to restrict power supply to the miner to force it to pay $132m of outstanding electricity bills. CEC announced the plan on 18 May, but KCM sought an injunction in the Kitwe High Court in an effort to overturn the decision.The case opened on 26 May and was adjourned to 22 June. In the meantime, the power supply to the mine remains uninterrupted.
