 And the Nigerian Bar Association says there is no constitutional nor legal authority that supports the ban of Twitter by the federal government. NBA president Ullumi Diakbata in a statement described the government's decision as illegal and threatened to challenge in court the decision of the government to suspend the operations of the microblogging site. Twitter had deleted a post by President Mohammad Ibarre on Tuesday, and this prompted the government to announce a ban. Minister of Information and Culture Lai Mohamed announced the suspension earlier on Friday, citing the persistent use of the platform for activities that are capable of undermining Nigeria's corporate existence.
