In Stitch v. AG, Federation & ors  LPELR-3119(SC), a case cited by the defendant but which proper citation the defendant did not give, His Lordship Aniagolu, JSC in the leading judgment defined a Minister as: “…a public officer charged by the Legislature of this country with the duty of discharging a public discretion affecting the citizens. He must discharge that function judiciously”.
The principle basic in all common law countries, including Nigeria, is that under the universally accepted Rule of Law, the Minister must act fairly and not to the prejudice of the citizen.
