16 December 2020: The Guardian reports that “The supreme court has overturned a February judgment that a third runway at Heathrow airport was illegal. It means the project can now seek planning permission, but the ultimate completion of the runway remains uncertain.
“The supreme court ruling marks the latest twist in years of legal and political wrangling over the climate impact and economic benefits of expanding the airport. The decision in February was seen as historic by environmental campaigners, as it was the first significant ruling in the world to be based on the Paris climate agreement, and related cases were subsequently brought against plans to build more roads and gas-fired power plants in the UK.”
““I still don’t think the third runway is going to happen,” said Tim Crosland, a lawyer at Plan B, which brought the legal case against Heathrow. “The really damaging thing [about the supreme court ruling] is the precedent for the other cases.” The Supreme Court ruling can be seen here. The Mayor responded to today’s ruling stating: ““I am disappointed with the court’s decision today to allow Heathrow Airport a third runway which will have a damaging impact on air quality, noise and London’s ability to achieve net-zero carbon by 2030.“
