On these facts of the customary arbitration by the Abuloma Council of Chiefs before whom the parties herein lead consensually submitted themselves to for the resolution of their dispute and the verdict of which arbitration was acceptable to all of them, it would no longer be open to either of the parties to subsequently back out or resile from the decision or verdict reached and pronounced upon the arbitration. See Oparaji v. Ohanu (1999) 9 NWLR (Pt. 618) 290, (2001) FWLR (Pt. 43) 385. The appellants are now estopped from resiling out of the customary arbitration of the Abuloma Council of Chiefs, which they voluntarily submitted their dispute with the respondents to, and agreed to accept the verdict of. Apart from this specie of estoppel operating as estoppel per rem judicatam; it also operates as estoppel by conduct by virtue of section 150 of the Evidence Act, 1990 (now section 169 of the Evidence Act, 2011). It is, therefore, unconscionable for the appellants, having by their words or conduct made the respondents to believe that they would be bound by the verdict of the Abuloma Council of Chiefs, to resile out of it and set up the suit, the subject of this appeal. See Joe Iga & Ors. v. Ezekiel Amakiri & Ors. (1976) 11 SC 1 at pages 12 – 13.
