Unfair dismissal – Determination whether dismissal fair or unfair. The employment tribunal had found that an employee had not been unfairly or wrongfully dismissed in circumstances where the employer had reasonably found him to have committed an act of dishonesty in respect of his expenses claims for mileage. The Court of Appeal, Civil Division, dismissed the employee's appeal as the tribunal had not failed to consider whether the employer had conducted a reasonable investigation into his response to the disciplinary investigations, where, what mattered, was the reasonableness of the investigation as a whole.
