Buhari submitted the certificate through his counsel, Wole Olanipekun.
The certificate was admitted as evidence in the matter.
It was presented by Abba Kyari, a witness Buhari called on Tuesday. He told the tribunal that Buhari had five credits including in English in the examination.
Kyari is the current chief of staff to the president.
The counsel representing the Independent National Electoral Commission, Yunus Usman, asked Kyari during cross-examination if he knew of Buhari having five credits in WASCE.
Kyari also told the tribunal that no certificate was listed on the president’s curriculum vitae and that none was among the documents obtained from Cambridge University earlier tendered as exhibits.
According to him, Buhari obtained the Cambridge documents personally on July 18, 2019.
The Peoples Democratic Party and its candidate, Atiku Abubakar, had filed the petition before the tribunal to challenge the victory of Buhari and the All Progressives Congress (APC) in the February 23, 2019 election.
One of the grounds of the petition was that Buhari did not possess the academic qualification required to contest the election.
