The document summarizes a case involving two homeowners, Mr. Williams and Mr. Waistell, who brought a private nuisance claim against Network Rail for allowing Japanese knotweed roots to spread from Network Rail's land onto the homeowners' properties. The homeowners were awarded damages at the first trial level to treat the knotweed and compensate for losses to their property values. However, Network Rail appealed the ruling, questioning whether the spread of the invasive plant constituted an actionable nuisance that deserved compensation under UK law. The document provides background on nuisance law, Japanese knotweed, and the initial trial judgment, setting up the subsequent appeal by Network Rail.

The encroachment claim was dismissed on the basis that to
be an actionable nuisance there had to be actual physical
damage, and none was established
The quiet enjoyment/Loss of amenity claim succeeded on

a proper value.
A County Court judge, Recorder Grubb, gave his judgment in 2017.
