LEGAL PRINCIPLE: EVIDENCE LAW – Estoppel – Res Judicata – Requirement of Identity of Subject-Matter
PRINCIPLE STATEMENT
To constitute estoppel the parties, subject-matter and issue must be the same. One cannot talk of Exhibit G in this regard. Besides, the land contained in the present appeal is bigger than the one contained in Exhibit G. Assuming without so holding that Exhibit G decreed title in the appellants, the fact that the appellants had acquired rights of possession over parts of 'ORON INYONG ANWASI' would not affect the right of the respondents to seek a declaration of title to the whole piece of land.

"To constitute estoppel the parties, subject-matter and issue must be the same. One cannot talk of Exhibit G in this regard. Besides, the land contained in the present appeal is bigger than the one contained in Exhibit G.

EXPLANATION / SCOPE
Res judicata requires identity of parties, subject-matter, and issue. If the subject-matter differs (e.g., present land is larger than the previous land), estoppel does not apply. A prior judgment on part of a larger land does not bar a claim for the whole land. Possession of parts does not affect the right to seek title to the whole. The party pleading estoppel must prove all three identities. Partial overlap is insufficient. The principle prevents misuse of estoppel to bar legitimate claims on different subject-matter. The court examines whether the prior adjudication covered the exact land in dispute. Mere overlap is not identity.
