            case involved subsidence damage caused to the plaintiffs house by an Oak tree growing in
            his neighbours (the defendants) garden. The soil was London clay and judgement was given
            against the defendant who was held liable for damages caused by the actions of his tree
            roots. Although the defendant had an insurance policy which had provision for accidents,
            the insurance company (the third party) would not pay out on such a claim because in their
            view, damage caused by the natural growth of a tree and its roots, could not be classified
            as an accident. The defendant sought a declaration in this case that the insurance company
            were in fact liable for this claim. 
            Judgement was given to the defendant and the insurance company were ordered to
            indemnify him for any sums which he may have to pay to the plaintiff.  
            It was held that the tree roots had caused an accident because, at a specific moment in
            time, they had caused an unexpected event which had then caused the overstepping of the
            building safety limit.  |
