"It is well settled that waiver is an abandonment of a right. Two elements must co-exist to constitute a waiver. First the party against who the doctrine is invoked must have knowledge or be aware of the act or omission which constitutes the waiver; and secondly, there must be on the part of the person against whom the doctrine is invoked, some unequivocal act adopting or recognizing the act or omission. See Olatunde v. Obafemi Awolowo University &
Anor. (1998) 5 NWLR (Pt.549) 178.
