R (o.t.a Seiont, Gwyfrai and Llyfni Anglers Society) v. Natural Resources Wales  EWHC 3578, Hickinbottom J, 17 December 2015, read judgment and
Chetwynd v. Tunmore  EWHC 156 (QB), HHJ Reddihough, sitting as a judge of the High Court, 4 February 2016, read judgment
This is a wintry double-bill on two recently decided cases about water quality, quantity, fish – and causation.
In the first, Seiont, Snowdonian anglers complained that the Welsh water regulator (Natural Resources Wales or NRW) had misunderstood what was required by the Environmental Liability Directive in respect of Llyn Padarn, a freshwater lake the home of the Arctic charr, Salvelinus alpinus. So they sought judicial review of NRW’s decision.
The main legal question was – did environmental damage within the Directive include slowing down recovery from previous damage, as the anglers argued, or was it confined to deterioration from an existing state (as the regulator had decided)?
Hickinbottom J held the latter, and the claim was dismissed.
In the second case, the claimant owners of fishing lakes in Norfolk said that their neighbours, in constructing rival lakes (without planning permission) had caused water levels to fall, and hence loss of fish and consequent income. Had that been established, the claimants would have had a claim for breach of statutory duty under section 48A Water Resources Act 1991. Such a claim, the judge held, would have been a strict liability one, in which foreseeability of damage played no part.
But the claimants lost on the facts, not before the judge had given an interesting analysis of the law of causation in this field.
