I propose to take Questions Nos. 131 and 139 together.
Planning legislation places no specific restrictions on the height of trees, nor does it make any particular provision for remedy from any other nuisance which may be caused by trees in an urban residential area. Complaints relating to matters such as trees or shrubs overhanging a property are normally addressed, where necessary, under civil law between the parties concerned.
I have no plans to develop legislation or guidelines for local authorities in this regard at present.
