155 If the tree is wholly on one person's land, the adjoining owner adversely affected by the tree may make application to the Court. This situation accords with the common law. If the tree is principally on one person's land, the adjoining owner would also have a right to make application to the Court. This accords with the common law where the tree could be said to be owned by the person on whose land the tree is principally situated (such as where the tree has moved), but not where the tree is jointly owned by the adjoining owners. In this situation, the Trees (Disputes Between Neighbours) Act 2006 is facultative. It allows one of the joint owners of the tree, namely the owner of the land adjoining the land on which the tree is principally situated, to apply for an order in relation to the tree without the consent of the other joint owner. But it is also restrictive in that the joint owner on whose land the tree is principally located cannot make application to the Court for an order in relation to the tree.
39 It is clear from:
- His Honour's final observation above on the terms of the Act;
- the terms of the Attorney-General's second reading speech when the legislation was introduced; and
- the report of the New South Wales Law Reform Commission which formed the policy discussion basis for the introduction of the legislation,
that it is not envisaged that an owner of land can take action against other owners of the same land for damage to the first owner's property which is situated on that land.
40 On Mr Ellison's submissions, there are three owners of the land on which the tree was located - the Spencers and Mr McCormack. The necessary conclusion follows that, if Mr McCormack is an owner for the purposes of the Act, he has made an application against his co-owners - the Spencers. If Mr Ellison be correct, it necessarily follows that the Court has no jurisdiction to entertain Mr McCormack's application as the joint owner on whose land the tree is principally located cannot make application to the Court for an order in relation to the tree.
Mr McCormack is an "owner" and the tree is situated principally on the land to the south
41 If, however, considering the second of the three possible elements of the matrix, Mr Ellison's submission is correct that Mr McCormack is an owner of the land but the tree was not situated principally on the Spencers' land but was situated principally on the land to south - being land jointly owned, on Mr Ellison's submissions on how "ownership" under the Act should be construed, by the owners of the fee simple of 88 Oyster Bay Road and the owners of 86 Oyster Bay Road as "owners" of the right of carriageway.
