A bid to stop Stansted Airport from expanding has failed in the High Court.
The Stop Stansted Expansion group argued that criteria used to decide options for runway sites was "infected by apparent bias".
Their complaints focused on Geoff Muirhead, who is a former chief executive of Manchester Airports Group, owner of the airport since February.
The group claimed that Mr Muirhead, a recently resigned member of the Airports Commission, had a conflict of interest.
However, Mrs Justice Patterson has come to the decision that no such action will be taken.
The judicial review was contested by the Airports Commission and the Department for Transport.
