Adeniji v. Fetuga (1990) 5 WLR (Pt. 150) 375 this Court per Akanbi J.C.A. (as he then was) held thus:- “A reply is the Plaintiff’s answer or response to any issue raised by the Defendant in his defence and which the Plaintiff seeks to challenge, deny or admit or object to either or ground of law or a mis-statement of the cause of action and it is not permissible in a reply to the defence to raise a new cause of action not set out in the writ of summons, for a Plaintiff must not in his reply make any allegation of fact or raise any new ground of claim different from what is contained in his statement of claim.”
COUNTER CLAIM – BE RELATED TO THE PRINCIPAL CLAIM
A counter claim to quote from Bairamien, JSC in Oyegbola v. Esso WA (1966) 1 All NLR 170 is a weapon of offence which enables a defendant to enforce a claim against the plaintiff as effectively as in an independent action. The counter-claim must be directly related to the principal claim but not outside of and independent of the subject matter of the claim. – Niki Tobi JSC. Okonkwo v. Cooperative Bank (2003)
