"In the leading case of British Home Stores Ltd v Burchell1980 ICR 303 , the Employment Appeal Tribunal set out a three part test to be considered when an employer seeks to show that a dismissal for a conduct reason is a fair reason. First, the employer must show that he believed the employee was guilty of misconduct. Second, that he had in his mind reasonable grounds upon which to sustain that belief, and thirdly, that at the stage which he formed that belief on those grounds he had carried out as much investigation into the matter was reasonable in the circumstances."
'Was dismissal an appropriate sanction?'
"More precisely, was the decision to dismiss one which a reasonable employer could have come to in the circumstances – was dismissal within the reasonable band of decisions?"
"Taking all those matters into account, we are satisfied that no reasonable employer would have imposed the sanction of dismissal. Instead it would have given a final written warning. Accordingly our judgment is that this was an unfair dismissal."
"(4) In any other case where the employer has fulfilled the requirements of subsection (1), the determination of the question whether the dismissal is fair or unfair (having regard to the reason shown by the employer) – (a) depends on whether in the circumstances (including the size and administrative resources of the employer's undertaking) the employer acted reasonably or unreasonably in treating it as a sufficient reason for dismissing the employee, and (b) shall be determined in accordance with equity and the substantial merits of the case."
"it is only in a very exceptional case, where an Employment Tribunal can be said to have come to a perverse conclusion, that the Employment Appeal Tribunal can interfere in the Employment Tribunal's determination as to the section 98(4) test, a determination which is essentially a question of fact"
"9.6 Wrongful dismissal Here we direct ourselves that we are making our own findings of fact as to whether gross misconduct occurred as opposed to the exercise we have been considering under the unfair dismissal claim – the position a reasonable employer would have taken. Having regard to the evidence that we have heard and the relevant findings that we have made, we conclude that whilst the Claimant was guilty of misconduct, that was not of such a degree so as to justify a summary dismissal. In other words it was not gross misconduct. Accordingly we find that in dismissing the Claimant without notice or payment in lieu of notice the Respondent acted in breach of contract and the dismissal was wrongful."
