A joint judicial review, challenging Heathrow’s plans to expand the west London hub via a third runway, was lodged last year.
However, the bid, split across five claims, was dismissed at the High Court on Wednesday morning (1 May).
A Heathrow spokesperson said: “We are delighted with today’s ruling, which is a further demonstration that the debate on Heathrow expansion has been had and won, not only in Parliament, but in the courts also.
"We are getting on with delivering the once-in-a-generation project that will connect Britain to global growth, providing thousands of new jobs and an economic boost for this country and its future generations.”
