In Gbagbarigha vs Toruemi (2013) 6 NWLR (Pt.1350) 289 at 310, paragraphs C-G as follows: “When a Judge raises an issue on his own motion, or raises an issue not in contemplation of the parties; or an issue not before the Court, the Court is said to have raised the issue suo motu. The well laid down position of the law is that when an issue is raised suo motu the parties should be heard before a decision is reached on the issue… but there is an exception to this procedure. There would be no need to call on counsel to address the Court on an issue raised suo motu by the judge:
1. When the issue relates to the Court’s own jurisdiction;
2. When both parties are not aware or ignored a statute which may have bearing on the case; or
3. When on the face of the record serious questions of the fairness of the proceedings is evident.”
EXCEPTIONS TO COUNSEL ADDRESSING ON SUO MOTO ISSUES
To raise an issue suo motu means that a Judge raised the issue which was not raised or which was not in contemplation of the parties. It is the law, that when raising an issue suo motu, the Judge should afford counsel or parties, an opportunity to address on it, before he can decide on it, especially the party that would be adversely affected by the issue. This is because, issue of fair hearing is thus involved – KUTI v. BALOGUN (1989) 1 NWLR (PT. 99) 566. However, there are exceptions to this law. Where (a) the issue relates to the jurisdiction of the Court, then it is not mandatory for the Judge to hear the parties on it; (b) when both parties ignored or were unaware of a statute which has a bearing on the case; (c) when the record ex facie, shows or discloses serious questions of the fairness of the proceedings.
