Aliadiere was sent off in the 85th minute of Boro's defeat by Liverpool

Gibson is furious that the FA instead added an extra match to the three-game ban which followed Aliadiere's sending off in Saturday's defeat at Liverpool.

He told BBC Sport: "We could have taken it on the chin if the appeal had simply been rejected.

"But to extend the ban by a further match, I find absolutely perverse."

Gibson's comments come after Middlesbrough accused the FA of double standards on Wednesday and took offence at the verdict that their appeal was "frivolous".

Boro chief executive Keith Lamb said Chelsea's appeal against Michael Essien's three-match ban was rejected but not thought "frivolous".

He added: "There is one rule for the big boys and another for the rest of us."

When Gibson was asked during half-time of his side's FA Cup victory over Sheffield United on Wednesday if the club had calmed down, he replied: "No, we haven't.

"The response we got from the FA was quite frankly not what we would expect from an organisation of that importance.

"We felt there were grounds to appeal, because of the inconsistency of the referee. And we didn't think Jeremie's offence was particularly violent.

"We began to research exactly what had gone on at the FA and we found that four individuals who have not been involved in the professional game at any serious level had stood judgment.

"I think they are of a level of competence which should not be tolerated at an organisation of that importance."

Responding to Boro's suggestion that not all Premier League clubs are treated equally, an FA spokesman told BBC Sport on Wednesday: "The FA refutes any suggestion that certain clubs are treated differently to others. All cases are treated on merit.

"Under Fifa guidelines, the FA can only overturn decisions if there has been a serious and clear error by the referee.

It is a disgraceful comment to suggest our claim was frivolous Middlesbrough chief executive Keith Lamb

"The vast majority of appeals are rejected on that basis. And the clubs are fully aware of the rules.

"If the appeal is considered to have been frivolous, then a further suspension can be added to the original ruling.

"This has happened to Burnley, Mansfield, Luton, Tranmere and Hartlepool this season - as well as Middlesbrough."

The first additional ban for a frivolous appeal was handed to Southend's Freddy Eastwood in August 2005.

Lamb is irate over the wording of the FA's response to Boro's appeal and feels it does not reflect the seriousness of the situation.

"It is a disgraceful comment to suggest our claim was frivolous," he stated. "We agonised over it before deciding to submit a claim for wrongful dismissal.

"The Oxford Dictionary definition of frivolous is, 'not serious, shallow, silly or trifling', while in fact we spent more than two days considering whether or not to appeal."

Frenchman Aliadiere, 24, was dismissed on 85 minutes by referee Lee Mason for striking out at Javier Mascherano.

The Argentine midfielder appeared to grab Aliadiere's face during Saturday's 3-2 Premier League defeat at Anfield.
