Although MPs unanimously backed the third runway, legal challenges are likely to substantially delay the start of construction.
Planning and infrastructure partner Angus Walker comments that the completion of the third runway is likely to be delayed by at least a year due to judicial reviews.
A number of parties have indicated that they are preparing to challenge the decision through the courts. Five boroughs – Hillingdon, Richmond, Wandsworth, Windsor and Maidenhead, and Hammersmith and Fulham – have stated that they would take legal action to overturn the decision.
Heathrow Hub, a rival proposal to the Heathrow expansion, has also said that it will launch a separate judicial review against the proposal.
Angus adds that legal challenges at this stage are likely to take several months:
‘There will likely be one or more judicial reviews in the High Court which could take up to six months.
The losing party could then appeal to the Court of Appeal, and even if they lose at the Court of Appeal they could then appeal to the Supreme Court.’
The challenge is also likely backed by the London mayor Sadiq Khan, who had pledged his support recently.
