It is settled law that issues for determination must be distilled from grounds of appeal which ground(s) must attack the ratio decidendi of the judgment not anything said by the way, or obiter dicta or be formulated in vacuo , as issue 5 in the instant case. – Onnoghen JSC. Chami v. UBA (2010)
PURPOSE OF ISSUE FORMULATION IN AN APPEAL
It is necessary to emphasise the purpose of formulating issues for determination in briefs. Like pleadings to a litigation between the parties the issues formulated are intended to accentuate the real issues for determination before the Court. The grounds of appeal allege the complaints of errors of law, fact or mixed law and fact against the judgment appealed against. The issues for determination accentuate the issues in the grounds of appeal relevant to the determination of the appeal in the light of the grounds of errors alleged. Hence the issues for determination cannot and should not be at large, but must fall within the purview of the grounds of appeal filed.
