From its tenor, therefore, the Court is required to conduct the trial or hearing of a case with all fairness to both parties to the suit and without bias or partiality in favour of, or against either party. That is the rationale for the prescription that a complaint of breach of fair hearing is usually against the Court or Tribunal, whether the parties before the Court were afforded equal opportunity to fully ventilate their grievance. Okanlawon v. State (2015) LPELR-24838 (SC) 52-53; E-B; Peters Pam and Anor v. Mohammed and Anor (2008) 5-6 SC (Pt. 1) 83; Deduwa v. Okorodudu (1976) NMLR 236, 246; 9-10 SC 329. Such is its primacy in our administration of justice that no decision can be regarded as valid unless the trial Judge or Court has heard both sides in the conflict. State v. Onagoruwa (1992) LPELR -3228 (SC) 33; D-E; Deduwa v. Okorodudu (supra). This test of fair hearing applies once a trial has commenced, after issue has been joined, State v. Onagoruwa (supra); nay more, it applies from the beginning to the end of the trial. Oyewole v. Akande and Anor (2009) LPELR-2879 (SC) 36-37; Deduwa v. Okorodudu (1976) 9 -10 SC 329; News Watch Comm. Ltd. v. Attah (2006) 12 NWLR (Pt. 993) 144; A. G Rivers State v. Ude (2006) 17 NWLR (Pt. 1008) 436.
