The House of Representative members on Wednesday rejected executive order on corruption signed by President Muhammadu Buhari recently.
Last week Buhari signed the executive aimed at restraining owners of assets under investigation access to them.
The president had said the order would help boost his administration’s fight against corruption.
The opposition Peoples Democratic Party has threatened to go to court to challenge the order describing it as a descent to fascism.
However, at plenary on Wednesday, Nicholas Ossai from Delta state, moved a motion seeking to suspend the order.
The motion was sponsored by 27 other lawmakers. They argued that the order usurps the constitutional powers of the national assembly to make laws and also hijacks the powers of the judiciary.
Majority of the lawmakers voted against it when it was put to a voice vote.
In protest, lawmakers of the All Progressives Congress (APC) staged a walkout.
