"Before parting with this matter, I would reiterate that wherever the trial of a preliminary issue or issues is ordered, and this includes orders for issues to be excluded from the trial, it is essential that the issues be clearly defined and that the judgment reflect that definition ... The ability to order the trial of preliminary issues is a most valuable tool which can, when properly used, assist the achievement of justice and save costs. What went wrong in the present case was not the concept of the trial of limited issues ... What went wrong was that the essential disciplines of the proper trial of preliminary issues were not observed."
"Where, as here, the relevant companies are carrying on business in different countries, the starting point must be that an income loss suffered by one company will normally not translate directly into an equal monetary loss to the other company ... The root principle which must be adhered to is that each company is a separate legal entity. The property of one is not the property of another. The plaintiff must prove its own financial loss in its own pocket and quantify it. Any other approach is contrary to the decided authorities and the principle in Saloman v A. Saloman & Co. Ltd."
