Please correct me if I am wrong. It is my understanding that any land owner can prune back the roots (and branches), of trees situated on neighbouring land,to his property boundary without seeking the permission of the neighbour (even if the trees are not causing any nuisance). 1. If the trees affected were to subsequently fall over who would be liable for the cost of the clear up/any resulting injury or damage to property? 2. Is there any case law where this has been tried?
