It is settled law that where a respondent filed neither cross-appeal nor respondent’s notice, he does not have an unrestrained or unbridled freedom to raise issues for determination which have no bearing or relevance to the ground(s) of appeal filed. – Onnoghen JSC. Chami v. UBA (2010)
A GROUND OF APPEAL CANNOT BE BASED ON AN OBITER DICTUM
The law is trite that a ground of appeal cannot be based on an obiter dictum. A ground of appeal is based on a ratio decidendi. An obiter dictum is, as a general principle of law, not binding on courts; a ratio decidendi is.
— Niki Tobi, JSC. Buhari v. INEC (2008) – SC 51/2008
