MTN Group has announced that its Nigerian mobile unit will challenge the fine it received from the Nigerian Communications Commission (NCC) in October for failing to meet a deadline to disconnect around 5.1 million unregistered subscribers. Earlier this month, the NCC reduced the NGN1.04 trillion (USD5.2 billion) fine by 25% to NGN780 billion, giving MTN until 31 December 2015 to pay the penalty. ‘MTN Nigeria, acting on legal advice, has resolved that the manner of the imposition of the fine and the quantum thereof is not in accordance with the NCC’s powers under the Nigerian Communications Act and therefore there are valid grounds upon which to challenge the fine,’ according to a statement from the South African group. Accordingly, MTN says it has instructed its lawyers to proceed with an action in the Federal High Court in Lagos, although the firm will continue to engage with the Nigerian authorities ‘to try and ensure an amicable resolution’. Pending the court hearing, the parties may take no further action until the matter is resolved.
