Buhari is convinced he has done enough to convince the court that he won the 2019 presidential election.

Buhari was declared the winner of the February 23 presidential election, but Atiku Abubakar, and his Peoples Democratic Party (PDP), rejected the result and sued to be declared winner instead.

Buhari opened defence of his case on Tuesday, July 30, but has now ended it after calling just seven witnesses, which pales in comparison to the 62 presented by the petitioners.

Buhari's lead counsel, Wole Olanipekun (SAN), announced the closing of his defence when proceedings resumed on Thursday.

He told the five-member tribunal panel the second respondent is satisfied with the case presented before the court.

"We are very satisfied with the evidence we have led and we will be closing our case as the second respondent," Olanipekun said.

The APC's counsel, Lateef Fagbemi, told the tribunal there was no need for the third respondent to call witnesses as it would be an "overkill".

"We for the third respondents say we have satisfied with the cross-examination and evidences tendered in this case," he said.

The first respondent, the Independent National Electoral Commission (INEC), failed to call any witnesses.

Presiding judge, Justice Mohammed Garba, proceeded to schedule the adoption of the final addresses for August 21.

INEC crowned Buhari winner of the February 23 election with 15,191,847 of the total votes cast while Atiku gained 11,262,978 votes.

However, in a petition filed before the tribunal, Atiku claimed that he actually won the election with 1.6 million more votes than Buhari according to an internal compilation of results he claimed was obtained from INEC's server.

According to the result obtained from the INEC server as claimed by Atiku in his petition, the former vice president actually scored 18,356,732 votes while Buhari scored 16,741,430 votes. This does not include results from Rivers State which had allegedly not been transmitted at the time Atiku claims the data was captured.

While filing its response before the tribunal on April 11, INEC accused Atiku and the PDP of producing fake election results to prove their case.

"INEC specifically denies the existence of electronic transmission of results and it is unknown to the Electoral Act 2010 (as amended)," the commission noted in its response.

Atiku also accused Buhari of not possessing the educational qualification to contest, alleging that he submitted false academic documents to INEC to aid his qualification.

In their counter to Atiku's petition, Buhari and the APC said the former vice president is not qualified to contest for the presidency because he was born in Adamawa State at a time when it was Northern Cameroon before it voted during a 1961 referendum to align with Nigeria.
