In a plaintiff’s pleading, he is required to show clearly and prove the nature of the possession which he is relying upon to sustain his action in trespass, that is whether he is relying on bare possession or on his possession or right to possession based on his title to the land. The rule of audi alteram partem, which is incorporated in our rules of pleadings postulates that a man must know the nature of the case which he is to meet in court. This is also a clear implication of the constitutional provision of fair hearing guaranteed by section 33 of our Constitution of 1979. As such is the case, a plaintiff cannot in his pleadings aver exclusive possession or right to possession based on title but, having failed to prove it, be allowed to succeed on bare possession.
