The Supreme Court and the Central Bank of Nigeria (CBN) are both important institutions in Nigeria, but they have different roles and responsibilities.

The Supreme Court is the highest court of appeal in Nigeria and is responsible for interpreting and upholding the country’s constitution. It is an independent arm of the Nigerian government and is considered the final authority on legal matters in the country.

The Central Bank of Nigeria, on the other hand, is the country’s central monetary authority and is responsible for regulating and supervising the nation’s financial institutions, maintaining price stability, and managing the country’s foreign reserves. The CBN also formulates and implements monetary policies in the country.

Both the Supreme Court and the CBN have specific powers and limitations defined by the Nigerian constitution and other laws. In general, it is not possible to compare the power of the Supreme Court and the Central Bank of Nigeria directly, as they have different mandates and areas of jurisdiction. Instead, they play important and complementary roles in the governance of Nigeria.

If a policy implemented by the CBN is challenged in court, the Supreme Court would review the policy and determine whether it conforms to Nigerian laws and the constitution. If the court finds that the policy violates the constitution or any other relevant law, it can declare the policy invalid and order the CBN to revise or rescind it. However, the Supreme Court would only intervene in cases where the CBN has exceeded its legal authority or violated the constitution.
