Performance director Gary Hall maintains GB Taekwondo followed Olympic selection protocol "to the letter" in making the "extremely difficult decision" to exclude European champion Aaron Cook, which was not ratified by the British Olympic Association.
Cook was widely anticipated to secure nomination for the under-80kgs category on a four-strong team, having retained his European title in Manchester at the start of May.
However, the 21-year-old, set to be ranked world number one ahead of the Games, was overlooked in favour of Lutalo Muhammad, who would have to drop down a weight division for the Olympics.
That prompted Cook to write to the BOA after an internal appeal to Sports Resolution Ltd returned the same outcome, and which saw last week's scheduled Team GB squad announcement postponed.
The BOA's Olympic Qualification Standards (OQS) panel met with GB Taekwondo on Thursday and have asked them to look again at the selection, raising certain issues over the process, including the weight given to head-shots and that all votes should be cast as well as asking for an "independent observer" at the next meeting.
Hall maintains the GB Taekwondo panel, which is made up of high performances coaches, had followed the guidelines set out in their own Olympic selection policy documentation, which was signed by all athletes who want to compete at the Games, and was not just based purely on results.
"We followed the process to the letter and considered everything we said we were going to consider in the selection procedure," said Hall.
"This panel takes its job very seriously, it had to select the best athlete to do the job in London.
"The professional opinions of these guys have taken British Taekwondo forward to historic performances over the last two years.
"There is no reason to suggest their decision making now is in any way shape or form flawed.
"It has been an extremely difficult decision to make, with two world-class athletes to consider.
"They have considered it professionally and with no bias, in accordance to the procedure everyone accepted when we started on this journey."
Cook indicated in a statement his decision to quit the British Taekwondo's World Class Performance Programme in Manchester and train independently counted against him among the votes of the rest of the selectors.
However, Hall stressed: "It does not matter whether you are inside the Academy, outside the Academy or work overseas.
"Wherever you are, it is about who is the best man for the job."
GB Taekwondo are considering their position before deciding whether or not to appeal against the BOA ruling - they have 24 hours to do so.
Hall added: "We have been asked to go back again and reform the selection panel and reassess it with some of the recommendations of the BOA have given us.
"We are considering over the next 24 hours whether to appeal that decision.
"If it is concluded we will not appeal, then we will reconvene the selection panel.
"We will take on the recommendations of the BOA, will do it with the barrister in the room, with the BOA witness in the room and will take the vote again.
"Whatever comes out, we hope it will be final and binding."
Cook, who has funded himself through a series of sponsorship deals after leaving Team GB's training programme, has not yet given up on his Olympic dream.
The 21-year-old said on Twitter: "Thank you to the BOA. Thanks also to all the public, fellow athletes and legends for your support. If given the chance, I will make GB proud."
The selection row overshadowed what has been an impressive build up to London 2012 by Hall's elite fighters, who returned from last year's World Championships in South Korea with four medals - including gold for Sarah Stevenson.
Tomorrow will see the three athletes whose nominations were ratified by the BOA confirmed.
Doncaster athlete Stevenson, a bronze medallist at the Beijing Games, has recovered well from a serious knee injury, and is understood to have secured the under-67kgs nomination.
Wales youngster Jade Jones, world silver medallist, will take up the under-57kgs place, while Liverpudlian Martin Stamper is set to fight for Team GB at under-68kgs.
