UK developer the Arora Group is appealing a judgment to the UK’s Supreme Court after the ruling found plans for a third runway at Heathrow Airport are illegal.

The appeal papers were lodged by the company established to build the Heathrow West terminal, controlled by Sanjay and Surinder Arora, that would service the proposed runway.

“Heathrow West remains an unwavering supporter of expansion and we believe that our plans to design, develop and operate the new terminal will revolutionise the airport and ensure an expanded Heathrow is efficient and cost-effective,” the company said in a statement.

The statement added that the developer was looking “to put Heathrow expansion back on track”.

The appeal follows a major loss for the plans for a third run in the Court of Appeal on Thursday.

The court ruled the expansion plans, as currently proposed, were illegal because UK law currently made it statutory for the country to reach net-zero-carbon emissions by 2050.

The ruling means any proposal for a third runway will need to be in line with current UK law. The new terminal would potentially accommodate as many as 40 million extra passengers at Heathrow annually.

“The consequence of our decision is that the government will now have the opportunity to reconsider the NPS [national policy statement] in accordance with the clear statutory requirements that Parliament has imposed,” said Lord Justice Lindblom in the court’s judgment.

“The Paris Agreement ought to have been taken into account by the secretary of state. The National Planning Statement was not produced as the law requires.”
