PRINCIPLE STATEMENT

Where parties consent to a particular issue being determined as a preliminary issue, they are bound by that approach and cannot later resile from it. The court correctly adjudicates what transpired between counsel based on their agreement.

RATIO DECIDENDI (SOURCE)

Per Ejiwunmi, JSC, in Ibori v. Agbi & Ors (2004) NLC-972003(SC) at pp. 22–23; Paras C–A.
"The sole issue was whether exhibit 'A' was a conviction of the person mentioned therein... It is clear in my humble view, that that court correctly adjudged what transpired between the court below and the learned counsel who appeared... Clearly therefore the approach of parties to this case before the lower court was to determine first whether or not exhibit 'A' could be evidence of conviction. It was not directed at showing in the first instance that the 5th defendant was the person convicted. Parties would appear to have reserved that for sometime later in the proceedings if the lower court decided that exhibit 'A' was good enough to be relied upon as evidence of conviction."
