Buhari is expected to swear in Justice Olukayode Ariwoola as the acting CJN today June 27 following Justice Ibrahim Tanko Muhammad resignation.
Justice Ariwoola, who is the most senior Justice of the Supreme Court, will be sworn in by 2pm at the Council Chambers of the State House, Abuja.
Sources said he will act as CJN pending the time his name will be forwarded to the Senate by the President for confirmation as substantive Chief Justice of Nigeria (CJN).
Born on 22 August 1954, Justice Ariwoola from Oyo state was formerly a Justice of the Court of Appeal before being elevated to the Supreme Court bench in 2011.
Tanko tendered his resignation on Sunday, June 26, citing his deteriorating health status.
