The Presidential Election Petition Tribunal, is now headed by Justice M. L. Garba, who is the Presiding Justice of the Lagos State Division of the Court of Appeal.
Garba, who appeared on the five-man Panel for the first time, on Monday, replaces the President of the Court of Appeal, Justice Zainab Bulkachuwa.
Bulkachuwa had withdrawn from the Panel, on May 22, following allegations of likelihood of bias levelled against her by the Peoples Democratic Party, PDP, and its Candidate in the February 23, Presidential election, Atiku Abubakar.
The Petitioners are challenging the victory of President Muhammadu Buhari and his All Progressives Congress, APC, in the election.
There are three other Petitioners challenging the outcome of the poll.
