However, in appropriate cases, the court is willing to lift the veil of incorporation when the justice of the case so demands and to treat the parent company and its subsidiary as one single unit. In the case of Hotel Jaya Puri Bhd v National Union of Hotel, Bar & Restaurant Workers & Anor [1980] 1 MLJ 109; [1979] CLJ 360; [1979] 1 MLRH 197, Salleh Abas FJ (as His Lordship then was) on behalf of the then Federal Court held: "It is true that while the principle that a company is an entity separate from its shareholders and that a subsidiary and its parent or holding company are separate entities having separate existence is well established in company law, in recent years the court has, in a number of cases, by-passed this principle if not made an inroad into it. The court seems quite wiling to lift "the veil of incorporation" (so the expression goes) when the justice of the case so demands. Thus the fact of the case may well justify the court to hold that despite separate existence a subsidiary company is an agent of the parent company or vice versa as was decided in Smith, Stone and Knight v Birmingham Corporation; $ ^{(1)} $ Re F.G (Films) Limited; $ ^{(2)} $ and Firestone Tyre & Rubber Company v Llewelyn. $ ^{(3)} $ Professor Gower in his Principle of Modern Company Law, 3 $ ^{rd} $ Edition, Page 213, said that the courts "are coming to recognise the essential unity of group enterprise rather than the separate legal entity of each company within the group. Other examples of this can be found. In The Roberta (1937) 58 LI L.R 159, a parent company was held liable on a bill of lading signed on behalf of its wholly owned subsidiary, the court saying that the subsidiary was 'a separate entity...in name alone and probably for the purposes of taxation'. In another case Spittle v Thomas Grit & Aggregates Ltd [1937] 4 All ER 101, the court found no difficulty in treating a subsidiary as 'to all intents and purposes' the same as the parent company which held 90 per cent of its shares. A licencing authority in exercise of its discretion has been held entitled to have regard to the fact that the parent and subsidiary company, though technically separate legal persons, in fact constituted a single commercial unit (Merchandise Transport Ltd v British Transport Commission [1962] 2 Q.B 173, Devlin L.J. at page 202) ...A good example of this is Bird & Co v Thos. Cook & Son [1937] 2 All ER 227, in which an indorsement of a cheque to "Thos. Cook & son Ltd' was treated as an indorsement to the allied but separate company of Thos. Cook & Son (Bankers) Ltd by regarding it as a mere misdescription to be ignored under the principle of falsa demonstration non nocet."
