It is trite to say that non-compliance with rules of court will not necessarily result in the judgment given in the case being set aside and it is also clear that once a step is taken in the proceedings by a party complaining about the breach of the rules of court he is said to have waived the breach. This was the decision of this court in the case of Jozebson Industries Co. v. R. Lauwers Import-Export (1988) All NLR 310 at 333; (1988) 3 NWLR (Pt.83) 429.
