Papua and New Guinea v Leahy

The High Court of Australia considered a dispute between the Territory of Papua and New Guinea and Mr. Leahy concerning the ownership of certain land. Mr. Leahy claimed that he had acquired title to the land through adverse possession, having occupied and used it for a significant period. The Territory, however, asserted its own proprietary rights over the land.

The central legal issue before the Court was whether Mr. Leahy's occupation of the land satisfied the requirements for establishing title by adverse possession under the relevant laws applicable in the Territory. This involved determining whether his possession was adverse in nature, continuous, exclusive, and of sufficient duration to extinguish the title of the Crown or its successor.

The Court analysed the nature of possession required for adverse possession, drawing upon established common law principles. It considered the evidence presented regarding Mr. Leahy's use and control of the land, and whether this amounted to a dispossession of the true owner. The judges applied the legal tests for adverse possession, focusing on whether the claimant's actions demonstrated an intention to possess the land to the exclusion of all others, including the Crown. The Court ultimately found that Mr. Leahy had not established the necessary elements of adverse possession.
