Justice Mohammed Garba, Chairman of the five-man panel, reserved the application after it was argued by counsel to the parties.
A National Chairman of Hope Democratic Party (HDP), Tapre Poland had approached the tribunal with the application.
The tribunal also reserved its ruling on another application filed by Poland, praying for the substitution of counsel representing the party.
Mr Anthony Agbolahan, counsel for Poland, had adopted and argued the written addresses of the applicant.
The applicant prayed the tribunal to grant the two applications, adding that HDP was no longer interested in contesting the victory of the president in the Feb. 23 general election.
Tapre, a member of the National Working Committee (NWC) of the party, assumed the position after the substantive National Chairman, Chief Ambrose Owuru, was suspended by the party.
News Agency of Nigeria (NAN) reports that Owuru, who contested the presidential election on the platform of HDP, is challenging Buhari’s victory in the election.
Mr Chukwunoyerem Njoku, Counsel for both HDP and Owuru, prayed the tribunal to discountenance the two applications, describing the applicant as an “interloper’’.
Njoku also argued that the applicant had no locus to file for the withdrawal of HDP, adding that he had no official power to do so.
Njoku said Poland was neither the National Chairman of the Party nor contested the Feb. 23 presidential election on the platform of HDP.
He further explained that only the National Working Committee (NEC), chaired by Owuru, who remained the National Chairman of HDP could decide whether or not to press on with the case.
Njoku, therefore, prayed the tribunal to disregard the application by dismissing same.
Justice Garba had earlier granted the petitioners leave to effect typographical corrections in their main petition but however declined additional prayers to file additional list of witnesses.
The chairman of the panel held that the 21 days allowed by law for the filing of a petition that should contain all list of witnesses and other documentary evidence had since lapsed.
Meanwhile, the tribunal adjourned until June 27 to entertain an application filed by INEC seeking the setting aside of the alleged “referendum’’ the petitioners were relying on to have won the presidential election.
