Key Facts
- •River Action UK, an environmental charity, challenged the Environment Agency's enforcement of the Reduction and Prevention of Agricultural Diffuse Pollution (England) Regulations 2018.
- •The case focused on the pollution of the River Wye due to high phosphate concentrations from agricultural sources.
- •The key legal dispute centered on the interpretation of Regulation 4(1)(a)(i), concerning the timing of fertilizer application in relation to crop and soil needs.
- •The Environment Agency's approach prioritized advice and guidance before formal enforcement, leading to concerns about the effectiveness of its enforcement.
- •The claimant also argued that the Environment Agency failed to adequately consider the requirements of the Habitats Regulations in its enforcement actions, given the River Wye's protected status.
Legal Principles
Regulators must enforce the law but have discretion in how they do so. A policy guiding enforcement is lawful unless it fetters discretion or is irrational.

Courts are reluctant to interfere with prosecutorial decisions, affording a significant margin of discretion.
R(Cornerhouse research) v Director of the Serious Fraud Office [2009] AC 756
A competent authority, in exercising its functions, must have regard to the requirements of the Habitats Directives, but may depart if justified. The scope for departure is narrower when the authority is the principal body responsible for fulfilling the requirements.

Statutory interpretation should avoid absurd or unworkable results.

Outcomes
The claim for judicial review was dismissed.
The court found the Environment Agency's enforcement approach, while containing inconsistencies, was not unlawful. The agency's policy was lawful, and its actions, while not perfect, demonstrated a genuine attempt to achieve compliance with the regulations. The court also held that the agency had properly considered its obligations under the Habitats Regulations.
Regulation 4(1)(a)(i) was interpreted to mean that fertilizer application should not exceed the immediate needs of the soil and crop at the time of application.
The court emphasized the regulations' purpose of reducing diffuse pollution by avoiding surplus nutrient applications. The language of the regulation and its context supported this interpretation, rejecting the argument that planning could consider future crop needs over a longer timeframe.
