Due to the N500 and N1000 ban, 10 states have taken Buhari to court.

  The supreme Court of Nigeria has been requested by ten state governments in Nigeria to over turn president muhamadu Buhari's decision to outlaw the old N500 and N1000 notes. 

In their lawsuit, filed on Friday by their attorney A.J. Owonikoko (SAN), the governors are asking the supreme court to declare the President's orders from his broadcast on Thursday to be unconstitutional.

The Attorneys General (AGs) of Kaduna, Kogi, Zamfara, Ondo, Ekiti, Katsina, Ogun, Cross River, Sokoto, and Lagos states are the plaintiffs in the lawsuit. The Attorney General of the Federation, Abubakar Malami (SAN), and the AGs of Bayelsa and Edo states are the respondents.

The plaintiffs claimed in a dozen grounds of application that Buhari's directives, including his ban on old N500 and N1,000 notes and his extension of the validity of old N200 notes for 60 days, were a "unconstitutional overreach and usurpation of the judicial power" of the Supreme Court because the case was already before the court.

The petitioners' attorney referred to Section 232(1), Section 6(6)(b), and Section 287(1) of the 1999 Constitution as amended, which guarantee that all people and authorities must obey the Supreme Court's rulings.

Following numerous complaints from Nigerians, the Central Bank of Nigeria (CBN) extended the deadline for the swap of old N200, N500, and N1,000 from January 31 to February 10; however, the Supreme Court ruled that the Federal Government, the CBN, and commercial banks must not continue with the deadline pending the resolution of a notice in regard to the issue on February 22.

To coexist with the new N200, N500, and N1,000 banknotes for 60 days, the President on Thursday ordered the apex bank in a national broadcast to put old N200 notes into circulation.

According to him, Nigeria no longer accepts the old N500 and N1,000 bills as lawful cash.

But there have been a number of responses and stern objections of the President's decree, including from governors of his party, the All Progressives Congress (APC).

Governors Nasir El-Rufai of Kaduna, Abubakar Badaru of Jigawa, Rotimi Akeredolu of Ondo, as well as many other prominent members of the ruling APC, have publicly criticized and faulted the President's directive, claiming that it lacks justification because the case is still pending before the Supreme Court.
