"Where it can be established that the Industrial Tribunal has misdirected itself in assessing compensation, that, no doubt, will or may constitute an arguable point of law. Nonetheless, having said that, and as a matter of practice, it needs to be known that the Appeal Tribunal will not interfere with awards of compensation, unless the error is shown to be something which could be described as more than trifling. The reason for that is a practical one: industrial tribunals have to work in practical conditions, and they are obliged to assess the amount of compensation quickly – and fairly of course – but they are bound of necessity to operate in a somewhat rough and ready way, and to paint the picture with a broad brush. It is in everybody's interest that that should be the case. It may mean that sometimes an employee will get a bit less than he might have expected; it may mean that sometimes an employer will have to pay a little more than he had expected. But, if the compensation were to be worked out accurately to the very last halfpenny, it would require prolonged hearings, elaborate interlocutory procedures and all sorts of refinements which would be wholly out of place in a procedure which is meant to be quick, open to the unrepresented, and simple. Of course, if there is a serious error and that can be shown, then the appeal tribunal will interfere. But it will not do so in respect of trifling amounts or unimportant errors."
