Chege Njihia v Peter Irungu Wainaina
The bottom line
#Kenya's Court of Appeal confirmed that a buyer who occupies land for over 12 years after an incomplete sale can defeat the title owner entirely.

#Res judicata arising from the dismissal of Case No. 622/89
The suit was not res judicata because Case No. 622/89 was dismissed for non-joinder of the registered owner and was not determined on the merits, and the parties were not the same.
The doctrine of res judicata under section 7 of the Civil Procedure Act requires that the matter in issue be directly and substantially in issue, between the same parties or those claiming under them, and that it be heard and finally determined by a competent court. Case No. 622/89 was dismissed on a technical ground of non-joinder of the registered proprietor, so the dispute was not conclusively determined on the merits. The parties to the two suits were also different. The plea therefore fails.
Whether the respondent proved adverse possession and whether time was interrupted by Case No. 464/95 and the succession cause
The respondent proved adverse possession; his family's occupation since 1972 was peaceful, open and uninterrupted, the 12-year period expired by 1984, and neither the eviction suit nor the succession cause interrupted it.
The elements of adverse possession - open occupation without force, secrecy or permission, with animus possidendi - were established. Wamaitha never asserted her ownership against Wainaina after the incomplete 1972 sale, and time began running when she declined to transfer. By 1984 title had accrued in Wainaina's favour. Case No. 464/95 was filed against Mugoiri only, after 23 years had elapsed, and targeted a different occupant; it could not interrupt the respondent's possession. The appellant never pursued a claim against the respondent until 2008.
Whether the trial court erred in relying on the alleged 1972 sale agreement
No error: the document was a note or memorandum within section 3 of the Law of Contract Act as it stood in 1972, and possession and part payment made it enforceable.
In 1972 contracts for the disposition of interests in land were governed by the Law of Contract (Cap 23), which recognised a memorandum or note and validated verbal contracts supported by part-performance. The agreement produced was a note within section 3, and there was possession and part payment, corroborated by PW2's uncontroverted evidence. The appellant, who claimed under a later purchase, produced no written or oral proof that Wamaitha sold to him. A double sale could not subsist; the first sale took precedence and generated a trust pending transfer.
Legal principles established
#- A suit dismissed for non-joinder of the registered proprietor of the land is not determined on the merits and cannot found a plea of res judicata against a subsequent suit joining that proprietor.
- Occupation of land under an incomplete sale contract, with possession and part payment, is adverse to the seller; time for adverse possession begins to run when the seller declines to transfer the property, and once 12 years expire the claim accrues against the seller and her successors in title.
- Litigation by a title-holder against one occupant after more than 12 years of adverse possession has accrued does not interrupt the possession of a different occupant in whose favour time has already run.
