This article will assess the case for reforming the Irish law on adverse possession to confer
additional protection on the owner. Assuming such reform is warranted, it is possible that
an existing judicial solution, known as the rule in Leigh v Jack, has already been devised.
Ontario’s experience with an equivalent rule, known as the inconsistent use test, is of
interest in this context and certain academic literature is discussed which explains why the
inconsistent use test was developed and argues in favour of its retention or resurrection. An
alternative model of protection is then analyzed: the English Qualified Veto System of adverse
possession introduced by the Land Registration Act 2002. I argue that a judicial or legislative
reincarnation of the rule in Leigh v Jack would be an extremely flawed method of reforming
the law in jurisdictions, such as Ireland, which are considering reform, as the Qualified Veto
System more effectively responds to the difficulties which the inconsistent use test appears
to be attempting to resolve. I conclude that such a Qualified Veto System, similar, although
not identical to the one introduced in England, should be introduced in Ireland.
