However, it has been variously defined or described as a bundle or aggregate of facts which the law recognizes as giving a Plaintiff a right to claim a relief or remedy against a defendant. It is thus, a factual situation which gives a person a right to judicial remedy. It is the operative fact or factual situation which gives rise to a right of action which itself is a remedial right EGBE Vs. ADEFARASIN (1987) 1 SC at 34 36.
