Lawyers acting for Spurs have written to the bodies who made the decision demanding answers about how the verdict was reached.
The Olympic Park Legacy Company, the Mayor of London and the government departments for sport and local government have until the end of April to respond when Spurs will then decide whether to launch a full legal challenge.
A Spurs club statement said: “At this stage the Club has not issued any proceedings against the Olympic Park Legacy Company or any other party in respect of the decision regarding the award of the Olympic Stadium.
“The Club’s lawyers have written letters to the OPLC, the Mayor of London, the Minister of Sport and the Secretary of State for Local Government and a separate letter to the London Borough of Newham raising a number of concerns with the processes which led to the award.
“The letters also requested – in the interests of transparency – for the provision of certain information concerning the processes, which the Club considers that it is entitled to.
“Tottenham Hotspur will determine its next step as and when it receives a response to these letters.”
