Further we see no prejudice to the Respondent if a third-party notice is taken out, a course of action which the Appellant had not objected to in the High Court and likewise here before us during submissions. The guidelines set out in the Supreme Court decision in the case of Tajjul Ariffin bin Mustafa v Heng Cheng Hong (supra) are instructive and they are these: “In his analysis of Chan Yee's case, K.C. Vohrah, J. pointed out - and we agree - that: there is nothing in the judgment to suggest that the plaintiff was required to amend his pleadings to take into account the added defendant nor is there anything therein to suggest that in opposing the application to add the co-defendant the plaintiff raised the issue that he would not be able to amend his Statement of Claim 12 to take into account the addition of another person as a co-defendant. And, next, dealing generally with both Hee Awa and Chan Yee's, he pointed out - and again we agree - that neither Hee Awa nor Chan Yee had whittled down the discretion of the Court of first instance in considering applications for joinder of defendants in running down cases of the sort before him and that the decisions therein were made on their own merits having regard to the particular facts. And then, turning to the merits of the case before him, the learned appellate Judge said this: The plaintiff had no objections to all the prayers except for prayer 3 that is, the prayer that the plaintiff do make the necessary amendments to the statement of claim against the rider of the motor cycle on which the plaintiff was pillion rider and against the master or principal of the rider. The plaintiff objected to the prayer on the ground that there is no substantive law to compel the plaintiff to sue another party and he raised the issue as to what particulars the Court would have to order the plaintiff to plead if the application for the prayer was allowed. The learned judge of the Sessions Court allowed prayers to 1 to 6 except for prayer 3 and she held the view that she could not compel the plaintiff to plead negligence against the intended co-defendant. This is what she said: 13 It is indisputable that adding the co-defendants would ensure that all matters in dispute (would) be effectually and completely determined. However, to compel the plaintiff to make the amendments sought involves substantive rather than procedural law. Can the defendant then also specify the particulars of negligence to be pleaded or compel him to amend his pleadings yet again if the particulars of negligence pleaded are not satisfactory? The learned appellate Judge went on to remind himself of the well known proposition that in an action in tort the plaintiff has a free hand as to who to sue. The plaintiff is not now, and never was, obliged to join as a defendant every person who was liable to him for that tort. He may, if he prefers, sue one or two; and the liability of the others will be no defence to those sued, and will not mitigate the damage recoverable, for all persons concerned in a common wrongful act are jointly and severally liable for all damage caused by it. (See Odgers, on Pleading and Practice, 20th Edn. p. 20). He then expressed his concurrence with the view of the learned Judge of the Sessions Court that to have granted prayer 3 of the defendant's application would have meant compelling the plaintiff to plead particulars of negligence against the intended codefendant when there was nothing on record to show that the intended co-defendant was negligent. And, towards the end of his judgment, he said this at p. para E line 3 to p. 38 A line 4: 14 Although the plaintiff had consented to the other prayers (and her counsel said he did so to save time as his objections in previous cases had been rejected) he objected to prayer 3 and he asked 'If Court allows application, what particulars will the Court order the plaintiff to plead? Do we plead particulars relevant to this case or not?' These are pertinent questions. He then concluded his judgment at p. 38 A lines 4 et seq as follows: Bearing in mind the case of Norbury Natzio another pertinent question which has to be asked earlier is-is there anything on record to show, on a reasonable and probable basis, that the proposed co-defendant was wholly or partly responsible for the accident? There is none. And to order the plaintiff to amend her statement of claim would be in effect to compel the plaintiff to sue a proposed co-defendant who for all one knows was not responsible at all for the accident and therefore not tortiously liable, and, more importantly, to compel the plaintiff to plead particulars of negligence against the proposed co-defendant which may well be non-existent. In my view, the learned Judge of the Sessions Court exercised her discretion correctly under O. 8 r. 6 (2) (b)on the material available before her in the case and I accordingly dismiss the appeal. 15 To revert to the question of law posed at the outset, we consider that the following general principles as to parties may be distilled from the Rules of Court and the authorities thereon.
