R (Friends of the Earth) v Secretary of State for Transport (Heathrow Third Runway)
[2020] UKSC 52
Independent editorial summary — not the official judgment. Read the full judgment via the source link.
Ratio Decidendi
When designating a National Policy Statement, the Secretary of State was not legally obliged to take into account the Paris Agreement targets on climate change where Parliament had not enacted those obligations into domestic law.
Facts
Environmental groups challenged the designation of the Airports National Policy Statement, which supported the Heathrow third runway. The Court of Appeal had held the NPS unlawful for failing to consider the Paris Agreement.
Judgment Summary
The Supreme Court reversed the Court of Appeal. While climate change was a relevant consideration, the Paris Agreement commitments did not form part of government policy in the sense required by the Planning Act 2008. The NPS was lawful.
Key Quotes
"The fact that the United Kingdom had ratified the Paris Agreement is not of itself a statement of Government policy in the requisite sense. Ratification is an act on the international plane."
— Lord Hodge and Lord Sales at [108](verbatim, verified against the judgment)
Subsequent Treatment
