My lords, the point needs to be re-iterated again and again that the cardinal principle of fair hearing whether in relation to a civil or criminal matter is so sacroscent. The Latin maxim puts it this way: “Audi Alteram Partem” i.e. let the other party be heard. It simply means: hear the other side(s) in a dispute before reaching a decision. It is a constitutional requirement (Section 36 of the Constitution of the Federal Republic of Nigeria, 1999 (as amended). This Court made several pronouncements that the principle of fair hearing has been incorporated in our jurisprudence that a man cannot be condemned without being heard. The principle is applicable in all cases in which a decision is to be taken in any matter, whether in a judicial, quasijudicial or even in purely administrative proceeding involving a person’s interest in a property, right or personal liberty. Let the other party be heard! See: Adigun v. AG Oyo State (1997) ? NWLR (Pt. 678) page; Oyeyemi v. Commissioner of Local Government, Kwara State & Ors (1993) 6 NWLR (Pt. 299) 344.
