Prosecution in Nigeria
A dual, executive prosecution — the Attorney-General of the Federation for federal offences and each State Attorney-General for state offences, both Cabinet ministers.
Facts on this page were checked against their sources on .
Prosecution is dual and sits inside the executive. The Attorney-General of the Federation is "the Chief Law Officer of the Federation and a Minister of the Government of the Federation" (section 150), with power to institute and undertake, take over, or discontinue criminal proceedings for federal offences (section 174). Each state mirrors this: a State Attorney-General, who is "the Chief Law Officer of the State and Commissioner for Justice" (section 195), holds the same powers for state offences (section 211).

A prosecutor decides whether a criminal case should be brought, on what charges, and presents it in court. This guide explains the tests applied, the duties owed, and how the role differs between systems.
- Why do justice systems need oversight?
