"3.2 An employee has committed a grave offence amounting to repudiation of contract, particularly in the more serious cases of dishonesty, insubordinate or violent conduct or disregard of security regulations."
"... in this modern industrial world if an employee deliberately uses an unauthorised password in order to enter or attempt to enter a computer known to contain information to which he is not entitled, that of itself is gross misconduct which prima facie will attract summary dismissal. Although there may be some exceptional circumstances in which such a response might be held unreasonable. Basically, this is a question of `absolutes' and could be compared with dishonesty. However, because of the importance of preserving the integrity of a computer with its information it is important that management should make it abundantly clear to its workforce that interfering with it will carry severe penalties."
"However that does not override or gloss the clear words of Section 57(3). It is not part of the ratio of that case that conduct in relation to a computer is an industrial offence which makes it automatically reasonable for an employer to treat it as a sufficient reason for dismissing a particular employee. The law is well established that a Tribunal must always apply the criteria set out in Section 57(3) of the Act. In our view the passage in Denco does not detract from that position. Furthermore an employer in considering an employees conduct will not act reasonably in treating conduct in relation to a computer as an automatically dismissable offence in the absence of a specific rule to that effect made known to all employees"
"We consider that the sanction of dismissal was too severe in all the circumstances. We bear in mind in this context Mr Rodrigues's ten years' unblemished service. Secondly, we bear in mind the information which he was trying to obtain was information to which he was entitled if he obtained it by telephone. We also bear in mind that the disciplinary procedure which is part of Mr Rodrigues's contract of employment makes provision for alternative sanctions, some of which are severe, directed to the reform of the employee rather than just getting rid of him. We bear in mind that British Telecom failed to focus its employees sufficiently on the likelihood that they would lose their jobs for unauthorised use of the system of the kind charged in this case. We think this is particularly important in the case of a newly introduced computer system. "
"The Tribunal considers that it would be just to reduce the basic and compensatory awards by 50% to reflect Mr Rodrigues's blameworthy contribution to his dismissal in flouting a legitimate instruction after he had been told that he could not have the access he had asked for."
"It seems to this appeal tribunal, therefore, that the law is quite plain and that what the industrial tribunal ought to do is, not to ask itself the question which this tribunal did - "Are we satisfied that the offence was committed?" - but to ask itself the question, "Are we satisfied that the employers had, at the time of the dismissal, reasonable grounds for believing that the offence put against the employee was in fact committed?"
"The first question that arises is whether the Industrial Tribunal applied the wrong test. We have had considerable argument about it. They said: `... a reasonable employer would, in our opinion, have considered that a lesser penalty was appropriate'. I do not think that that is the right test. The correct test is: Was it reasonable for the employers to dismiss him? If no reasonable employer would have dismissed him, then the dismissal was unfair. But if a reasonable employer might reasonably have dismissed him, then the dismissal was fair. It must be remembered that in all these cases there is a band of reasonableness, within which one employer might reasonably take one view: another quite reasonably take a different view. One would quite reasonably dismiss the man. The other would quite reasonably keep him on. Both views may be quite reasonable. If it was quite reasonable to dismiss him, then the dismissal must be upheld as fair: even though some other employers may not have dismissed him."
