Tottenham will write to the Football Association to express their anger at the way Robbie Keane's red card appeal was dealt with.
Keane failed in his attempt to overturn the three-game ban received after his sending off against Birmingham.
And Spurs officials are furious that their captain was not given the opportunity for a hearing.
"The justification for upholding the referee decision makes no sense to us," said club secretary John Alexander.
Keane, 27, was sent off by referee Phil Dowd for a tackle on Fabrice Muamba but Tottenham argued that the decision was harsh and that Dowd appeared to consult with the fourth official before producing a red card.
He added: "If Robbie had been given an opportunity to attend - the current rules do not give him any opportunity to attend at the hearing of his appeal - we believe that the verdict would have been different."
The striker's three-game ban will see him miss Premier League games against Manchester City and Portsmouth and the Carling Cup tie against Sven-Goran Eriksson's side.
"I'm convinced it was not a red card," said Spurs assistant manager Gus Poyet after Sunday's game.
"We know the referee asked the fourth official for his view but he was only a few yards from the ball.

"It's a new rule for me. I thought the referee was in charge of the game but maybe the fourth official was in charge in this game."
However, a spokesman for Professional Game Match Officials - the referees' governing body - denied this had been the case.
"Phil spoke to (fourth official) Uriah Rennie to inform him of the decision he was taking," he said.
"He did this to aid the management of the technical areas.
"The reason why referees, assistant referees and fourth officials are miked up is in order to improve the management of these types of situations."
Keane had scored twice before he was sent off - only the second red card of his career - and Tottenham went on to lose the match 3-2.
"I didn't think it was a bad tackle," said Keane.
"It was just a collision. I'm not a malicious player. I'm disappointed, but most of all I'm disappointed we didn't get something out of the game."
