We do not think Sze v Kung has the effect for which the Respondents contend. There, the plaintiffs were the registered owners of land. In 1955, the defendant began occupying the land. In 1961, operating under a mistaken belief as to the ownership of the land, the Crown granted the defendant a land permit entitling him to occupy it “for a temporary period” and to erect buildings upon the payment of a fee. In 1988, the Crown discovered that the land was privately owned and cancelled the permit, but the defendant continued to occupy the land for another two years. Throughout this time, the plaintiffs were unaware of the Crown’s permit. In 1990, the plaintiffs sued to recover possession from the defendant. It was accepted that when the defendant occupied the land in 1955, the plaintiffs were dispossessed of the land. The Privy Council reasoned that in 1961, “the effect of the permit was that [the defendant] possessed [the land] on behalf of the Crown”, who took the benefit of the defendant’s possession for the duration of the permit. This was because, “[b]y accepting the benefit of the permit, [the defendant] became estopped from denying that the Crown had the right to allow him to occupy” (at 1235E–F). Nonetheless, the defendant’s possession, whether on his own behalf or on behalf of the Crown, was adverse to the plaintiffs. Since the Limitation Ordinance was “not concerned with whether the defendant has acquired a title but with whether the plaintiffs’ right of action has been barred” (at 1236B–D), the plaintiffs failed to recover possession as their title was found to have been extinguished around 1975, when the 20-year limitation period expired. That was a time when the defendant would still have been possessing the land on behalf of the Crown. The fact that the defendant could not have denied the Crown’s title between 1961 and 1975, however, did not stop the limitation period from running adversely to the plaintiffs. That the defendant was not in possession on his own behalf when adverse possession crystallised was irrelevant because all that mattered was whether the plaintiffs’ right of action had been barred. The Privy Council stated the position thus (at 1236B-D):
