Does anyone know when strict liability is imposed in English Environmental law?

Answer 1

Try reading the following case and article:

~ Rylands v Fletcher (1868) LR 3 HL 330

~ Clean Water and Muddy Causation: Is causation a Question of law or fact, or just a way of allocating blame? - Padfield, N

Answer 2

Environment Act 1995

Contaminated land provisions. Affirmative duty imposed on local authorities to survey their land and force clean-up of dangerously polluted sites.

Water Resources Act 1999

Effective 1 May 1999
Little noticed when it came into effect but potentially very significant in its compulsory clean-up provisions.
Some overlap with Environment Act 1995

There is also the Environmental Liability Directive.
