The Court of Session found that via Lord Glennie said the case against Mr Emerson personally was bound to fail.
In MCA Records v Charly Records Ltd, the principles of personal liability are as follows :-
First, a director will not be treated as liable with the company as a joint tortfeasor if he does no more than carry out his constitutional role in the governance of the company – that is to say, by voting at board meetings. That, I think, is what policy requires if a proper recognition is to be given to the identity of the company as a separate legal person. Nor, as it seems to me, will it be right to hold a controlling shareholder liable as a joint tortfeasor if he does no more than exercise his power of control through the constitutional organs of the company – for example by voting at general meetings and by exercising the powers to appoint directors. … I would hesitate to use the word ‘never’ in this field; but I would accept that, if all that a director is doing is carrying out the duties entrusted to him as such by the company under its constitution, the circumstances in which it would be right to hold him liable as a joint tortfeasor with the company would be rare indeed. …
Second, there is no reason why a person who happens to be a director or controlling shareholder of a company should not be liable with the company as a joint tortfeasor if he is not exercising control through the constitutional organs of the company and the circumstances are such that he would be so liable if he were not a director or controlling shareholder. In other words, if, in relation to the wrongful acts which are the subject of complaint, the liability of the individual as a joint tortfeasor with the company arises from his participation or involvement in ways which go beyond the exercise of constitutional control, then there is no reason why the individual should escape liability because he could have procured those same acts through the exercise of constitutional control. … “
So its not always a given in IP to add an individual be careful but MCA is always a useful starting point.
