THE latest round of a battle over the sale of Stansted Airport took off at the Court of Appeal.
Three judges in London are being asked to rule in a challenge brought by airport operator BAA.
In 2009 the Competition Commission ruled BAA must sell Stansted and two of its other UK airports.
BAA has mounted a series of legal challenges against the decision, which have so far been unsuccessful.
The latest blow to Spanish-owned BAA came earlier this year when it lost an appeal before the Competition Appeal Tribunal.
The action is before Lord Justice Mummery, Lord Justice Rimer and Lord Justice Sullivan.
Since the Competition Commission’s decision, BAA has sold Gatwick Airport and faced with having to dispose of either Edinburgh Airport or Glasgow Airport.
It has opted to sell Edinburgh.
The judges reserved their ruling and are expected to give a decision on the appeal on Thursday.
