"In all such cases the employer has a choice either to believe or not to believe an employee, to take into account some evidence to discount other evidence and to come to a view at the end on the balance of probabilities. It is not required of the employer to come to a view as in a criminal proceedings that an offence has been committed beyond reasonable doubt. In this case there was ample evidence to conclude that Mr Evans had committed the offences which are referred to by Mr Nelson in the notes of the disciplinary hearing and in the letter confirming the dismissal."
