This legal briefing note has been prepared by No5 Chambers to assist LPAs affected by nutrient neutrality, and will be updated as the legal and policy context evolves. We commissioned it with the aim of setting out the legal principles of the Habitats Regulations in the context of nutrient neutrality, and the implications for decision-making by LPAs in their role as Competent Authority. Please note that this is intended to assist LPAs and is not official advice from PAS. We would advise that you discuss any legal matters with your own legal team.
