A campaign group named STOP Stansted Expansion has taken the Airports Commission (AC) to the High Court.
Later this week (November 22nd), representatives from the organisation, which is opposed to the further development of Stansted Airport, will make their case to Justice Ouseley that a neutral investigation into expansion plans was affected by bias.
Lawyers from the group allege that Geoff Muirhead's, former chief executive of Manchester Airports Group, involvement in determining the AC's criteria for expansion plans meant it was biased, reports the Herts and Essex Observer.
STOP Stansted Expansion chairman Peter Sanders said: "It is not enough just to remove Mr Muirhead from the commission at this advanced stage and that is why we will be asking the High Court to order [another inquiry]."
Manchester Airports Group, which owns Stansted, is opposed to calls for a new commission inquiry, as this will stall its efforts to improve service at the airport.
