Aaron Cook's bid to compete at London 2012 appears set for the High Court after the British Olympic Association have rejected his latest appeal and refused to re-open the case.
The world number one claims to have been "cheated" out of an Olympic place after the BOA sanctioned GB Taekwondo's selection of Lutalo Muhammad in the -80kilogram class.
Muhammad is ranked 59 in the world and secured his place in Team GB after a controversial procedure, which required three selection meetings before the BOA were satisfied.
Cook's camp maintain the GB Taekwondo selection process was flawed and his lawyers Harbottle and Lewis outlined their case, including new evidence, in a letter sent to the BOA last week.
After taking advice from in-house and external counsel, the BOA have ruled there was not sufficient new evidence for GB Taekwondo to be forced to re-open its selection process.
Cook's camp had warned they would be prepared to take the case to the High Court or the Court of Arbitration for Sport in Lausanne if the BOA refused to consider the new evidence.
In the same statement, the BOA declared that CAS was "not the correct forum" because Cook had not been nominated for selection.
The full statement read: "It is the view of the BOA that the Court of Arbitration for Sport is not the correct forum for Aaron Cook's claims to be heard, as the relevant provisions of the Olympic Charter regarding the jurisdiction of CAS and the Olympic Games relate primarily to athletes who have been nominated for selection by their National Governing Bodies.
"It is also the view of the BOA that the letter and evidence from Aaron Cook's attorneys does not provide sufficient new information for the BOA to direct GB Taekwondo to reopen its selection process."
The new evidence sent to the BOA included an article from taekwondo news website, Mastaekwondo.com, published in February, which suggested Cook's omission had been pre-determined.
