The old naira notes must be used until December 31 of this year, the Supreme Court ruled on Friday.
The apex court ordered the Central Bank of Nigeria (CBN) to allow both the old and new naira notes to circulate side by side till the end of the year.
All orders given by President Muhammadu Buhari regarding the redesign and circulation of the naira were revoked and overturned due to violations of the law and abuses of the executive branch.
President Buhari received criticism from the supreme court for breaching its temporary order from February 8 allowing the old naira to be used in commerce.
The President demonstrated and elevated disobedience with his broadcast on February 16 in which he permitted just N200 notes alone, according to Justice Emmanuel Akomaye Agim.
