The Supreme Court has adjourned until March 3, when it will deliver judgment in the suit challenging the naira redesign policy of the Central Bank of Nigeria (CBN).
The decision was taken by the seven-member panel of the apex court on Wednesday.
Six more states — Rivers, Kano, Niger, Jigawa, Nasarawa, and Abia — joined the suit when it came up for hearing.
It brings the total of states to 16.
The suit was initiated before the Supreme Court by Kaduna, Kogi, and Zamfara states.
The states are seeking to restrain the federal government from giving effect to the deadline on the use of old N200, N500, and N1,000 notes.
On February 8, the supreme court restrained the CBN from giving effect to the deadline following an ex parte application brought by the three states.
Subsequently, several states approached the apex court to be joined in the suit.
