“It is probably strictly correct to say that as long as the offending condition is confined to the defendant’s own land without causing damage it is not a nuisance, though it may threaten to become a nuisance. But where damage has accrued the nuisance has been caused.”
“there was a continuing nuisance during Flecksun’s ownership until at least the completion of the underpinning and the piling in July 1992. It matters not that further cracking of the superstructure may not have occurred after March 1990. The encroachment of the roots was causing continuing damage to the land by dehydrating the soil and inhibiting rehydration. Damage consisting of impairment of the load-bearing qualities of residential land is, in my view, itself a nuisance…. Cracking in the building was consequential. Having regard to the proximity of the plane tree to Delaware Mansions, a real risk of damage to the land and the foundations was foreseeable on the part of Westminster, as in effect the judge found. It is arguable that the cost of repairs to the cracking could have been recovered as soon as it became manifest. That point need not be decided, although I am disposed to think that a reasonable landowner would notify the controlling local authority or neighbour as soon as tree root damage was suspected. It is agreed that if the plane tree had been removed, the need to underpin would have been avoided and the total cost of repair to the building would have been only£14,000 . On the other hand the judge has found that, once the council declined to remove the tree, the underpinning and piling costs were reasonably incurred …”
“what is called a continuing cause of action is a cause of action which arises from the repetition of acts or omissions of the same kind as that for which the action was brought.”
“If once a cause of action arises, and the acts complained of are continuously repeated, the cause of action continues and goes on de die in diem.”
