The binding legal principles established are: (1) Under section 4 of the Prescription Act [Chapter 8:11], a person becomes owner by prescription through open possession 'as if owner' for an uninterrupted period of 30 years, including by tacking (adding) periods of possession by predecessors in title. (2) Civil possession requires both corpus (physical control) and animus domini (owner-like intention), and must be nec vi, nec clam, nec precario (neither by force, nor by stealth, nor precariously). (3) Section 6(1)(c) of the Prescription Act postpones completion of prescription where the person against whom or in favour of whom prescription is running is deceased and no executor has been appointed, but only where the period would otherwise complete before or within three years after the impediment ceases; it does not postpone completion indefinitely where successor possessors continue in open, owner-like possession—the 'person in favour of whom prescription is running' at the point of completion is the current civil possessor(s) who may add predecessor periods. (4) A claim for recognition and registration of ownership that has already vested by operation of acquisitive prescription is a claim founded on a real right (ownership), not a 'debt' within the meaning of extinctive prescription provisions applicable to personal claims for performance. (5) Section 3 of the Titles Registration and Derelict Lands Act [Chapter 20:20] is a remedial registration statute that provides a mechanism to translate a 'just and lawful right to ownership' (acquired by prescription or otherwise) into the public register where ordinary conveyancing is blocked by death, incapacity, absence, or any other cause. (6) Where opposition is entered in Titles Act proceedings, section 10 empowers the court to determine the controversy speedily and inexpensively, including by directing trial of factual issues, and to make orders that are practically capable of implementation by the relevant registering authority. (7) Registration ordered under section 3 has, by virtue of section 13, the same substantive effect as a regular transfer and is vulnerable (or invulnerable) to the same grounds of challenge that would have applied had the property been regularly transferred.
