A major authorized victory in a case introduced by a householder affected by Japanese knotweed has raised the prospect of a rise in claims from folks tormented by the hazardous plant.
The court docket of enchantment dominated {that a} home-owner might recuperate damages for a lack of worth of their property from having had Japanese knotweed, even when it had been handled.
Marc Davies was awarded £4,900 from Bridgend council in south Wales in a judgment that his lawyer, Tom Carter, mentioned established that one might recuperate damages for the stigma connected to the home, even after knotweed had been eradicated, and never simply bodily harm brought on by it.
“Inevitably, if you’ve had knotweed and then had it treated, the rhizomes (roots) are still there in the ground, even though it’s been treated,” he mentioned. “There’s then a stigma that’s attached [to the house].
“The importance of Davies is that it has confirmed beyond doubt that that loss [on the house value] can be recovered and that’s really the crucial issue.
“If the court of appeal had said no on that point, then anyone affected by knotweed could get the treatment costs but then they’d be left out of pocket for this loss of value of their home. And if they were to sell their home a year, five years later or whenever, they’d still suffer a loss at that point they wouldn’t have been able to recover.”
Japanese knotweed can take 5 years to deal with. It can develop to 3-4 metres in simply 10 weeks and its rhizomes can unfold 7 metres horizontally underground and compromise the construction of buildings.
The species was launched by botanists into Britain within the nineteenth century as a decorative plant, with Victorian engineers purportedly utilizing it to stabilise railway embankments. Network Rail – together with native authorities – finds itself because the defendant in numerous circumstances.
The precept that adjoining house owners could possibly be sued for encroachment of Japanese knotweed was established by the court docket of enchantment in a 2018 case, which Carter additionally acted in, introduced by the house owners of two adjoining bungalows in Maesteg, south Wales, in opposition to Network Rail.

Chun Wong, associate at Hodge, Jones & Allen solicitors, mentioned the Davies case would most likely encourage claimants at a time when the variety of circumstances was already rising.
She mentioned: “It’s talking about what happens after the knotweed has been treated so it’s been found in the garden, hasn’t caused physical damage per se, but just having its presence because of the stigma attached … means somebody is going to pay less for this house than if the house had no knotweed at all.

“Whether this will open floodgates, I think time will tell. I suppose it just makes it easier for homeowners who have the presence of knotweed without actual physical damage to think: ‘Maybe I should make a claim.’
“The public are more aware and more educated about knotweed, the dangers of knotweed … and so, therefore, people are more prepared to litigate over it.”
Carter estimates he has already acted in 200 circumstances referring to Japanese knotweed and has one other 100 excellent.
He mentioned: “The knotweed landscape probably will stay [busy] for the foreseeable future … and I can see defendants probably fighting more in that they no longer have an argument about claimants being unable to recover for diminution [of property price], so the value of the claims are higher.
“Whether it leads to an increase in claims I don’t know because I’ve got hundreds already and it’s been going on for years now – but I can’t see the issue going away.”
A Network Rail spokesperson mentioned: “It will take some time to review the judgment and its implications. However, we do take quick and decisive action when we are notified of knotweed issues on our land.”
