Landmark Japanese knotweed decision in Court of Appeal


A recent landmark verdict at the Court of Appeal relating to the Davies v Bridgend County Borough case could signal a wave of Japanese knotweed litigation.

What is Japanese knotweed?

Japanese knotweed is a particularly destructive plant. It can grow in most soil conditions found in the UK and in man-made structures such as roads and buildings. Once spread, it can be extremely difficult to remove and can damage the structural stability of building foundations and walls. The mere presence of Japanese knotweed can devalue a property’s value significantly.

Davies v Bridgend County Borough

Mr Davies had Japanese Knotweed in the garden of his terraced house and claimed this had spread from a Council owned cycle track. He claimed devaluation in the value of his premises. 

At the initial Hearing in Swansea County Court, he was denied compensation because the Judge ruled that although the Japanese Knotweed constituted a “nuisance” in law, there were no damages payable where the only loss was purely economic. Mr Davies appealed to the Circuit Judge of the Court and the initial decision was affirmed.

Mr Davies then appealed to the Court of Appeal. The Court of Appeal decided pure economic loss was recoverable in a nuisance action and Mr Davies was awarded £4,900 in damages. According to law reports in The Times, the dispute will cost the Council about £300,000 in legal costs.

The barrister representing Davies at the Appeal Hearing said “it confirms that a homeowner who suffers a loss in the value of their home from the stigma left by Japanese Knotweed even after it has been treated can recover damages for that loss”.

It is believed this is the first Court of Appeal decision ruling on Local Authority liability.
