Nuisance – Private nuisance. The recorder's conclusion, that the presence of knotweed on the defendant's land near the claimants' properties had been an actionable nuisance simply because it had diminished the market value of the claimants' properties, because of lender caution, had been wrong in principle. However, the Court of Appeal, Civil Division, held that there was no reason why the claimants should not be able to succeed on the ground of an unlawful interference with their enjoyment of the amenity of their properties due to the impairment of their right to use and enjoy those properties.
