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)
TERMS OF SETTLEMENT MUST RELATE TO PLAINTIFFS CLAIM BEFORE IT CAN BE ENFORCED
I respectfully share the same view with the learned counsel for the 2nd – 14th respondents that jurisdiction of the court to enter judgment in accordance with the terms of settlement reached by parties is circumscribed by the claims filed before the court. If the terms of settlement are not within the purview of the plaintiff’s claim, it will be difficult for the court to allow filling of the terms, which will form the basis of the court judgment. The judgment of the court must reflect the claims before the court. This is so because it is a well settled principle that the court has no jurisdiction to grant a relief that has not been claimed.
