As a fallout of the tirade of allegations of corruption levelled against the Speaker, Yakubu Dogara, three principal officers and some members of the lower chamber, the House on Wednesday had voted to refer him to the Ethics committee for investigation.
The motion recommended suspension for a period not less than six months.
Abdulmumin had however noted that he would not appear before the committee unless the proceedings are allowed to be made public with civil societies organisations and labour unions in attendance.
But the Chairman of the House Committee on Media and Publicity, Hon. Namdas Abdulrazak, addressing journalists, said the committee headed by Hon. Ossai Ncholas Ossai, would decide on how to undertake its investigation.
“The committee would decide by itself, it is not for Abdulmumin to set agenda on how the committee should run. He is not the Chairman of the Ethics Committee, he was Chairman of Appropriation Committee,” Namdas said.
