The World Boxing Council has upheld its decision to issue an indefinite ban to Dereck Chisora following a meeting of the organisation's Supreme Board of Governors in Mexico City.
The WBC announced in February that they would not allow Chisora to fight again under their jurisdiction until he had completed anger management classes, following his post-fight brawl with David Haye in Munich.
They have now reiterated their stance in a statement which declared Chisora's behaviour prior to his fight with Vitali Klitschko - in which he slapped his opponent at the weigh-in and spat water at the WBC heavyweight champion's brother Wladimir shortly before the bout - had "never been seen before in boxing".
The statement went on: "The WBC followed its rules and regulations due to the fact that Chisora has not even showed any sign of regret or apology.
"The WBC concluded that with his acts he put in danger the development of the bout.. and it was considered that he stained the credibility of boxing as any boxer ever to be known had committed so many acts of aggressiveness, disrespect and mockery of 'fair play', in addition to have violated several disciplinary rules of the organisation."
Chisora's promoter Frank Warren issued an angry riposte in which he said Chisora had originally been told the hearing would be in London, and that he could not go to Mexico City due to being in training for his upcoming bout with Haye.
In the statement, Warren's organisation said they were "not surprised" by the WBC's verdict, and added: "The response of the WBC is heavy-handed and inconsistent with the approach they have taken over other fighters."
