The binding legal principles are: (1) A registered owner establishes prima facie ownership through deed of transfer, satisfying the first requirement of rei vindicatio; (2) Once ownership and possession by another are proved, the onus shifts to the possessor to establish lawful retention; (3) For acquisitive prescription under section 4 of the Prescription Act [Chapter 8:11], the claimant must prove open, adverse, and continuous possession with animus domini for an uninterrupted period of 30 years; (4) Fragmented evidence of occupation does not satisfy the strict legal requirements for acquisitive prescription; (5) Mere delay by a registered owner does not establish acquisitive prescription; (6) The special status of diplomatic property under the Vienna Convention on Diplomatic Relations and the Privileges and Immunities Act [Chapter 3:03] is a relevant consideration in assessing claims of abandonment of such property.
