The Chief Justice of Nigeria (CJN) Justice Ibrahim Muhammad has resigned to enable him attend to his health.

His media aide, Ahuraka Yusuf Isah confirmed this in a terse statement a moment ago.

Although Isah had earlier denied knowledge of the development, he said the next most senior Justice of the Supreme Court, Justice Olukayode Ariwoola would be sworn-in later on Monday by President Mohammadu Buhari.

Justice Muhammad was also absent today at a training workshop for judges, organised by the National Judicial Institute (NJI) which he was expected to declare open.
