Tottenham have applied for a judicial review into the decision to award the Olympic Stadium to Premier League rivals West Ham.
Spurs were beaten in the race to take over the facility following the 2012 London Games, and remain unhappy about Newham Council providing a loan to the Hammers to aid the “conversion” of the ground.
As a result, the White Hart Lane outfit have now asked the High Court to look into the process that was undertaken to determine who would move into the stadium.
A statement on the club’s official website read: “The club has on Wednesday sought permission from the High Court to bring a claim against the London Borough of Newham ("Newham") for judicial review of Newham's process in providing a loan for the conversion of the Olympic Stadium after the 2012 Games.
“The club wrote to Newham asking it to explain its reasons and justification for its decision, but Newham has declined to respond to this request for information.
“Due to the time limits which apply to claims for judicial review, the club has had no alternative but to issue these proceedings in order to protect its position.
“The club continues to hold discussions with both local and national government bodies in order to seek to agree a feasible stadium solution.”
