Whether the application should be granted
22 AMP submitted that the quantum of the plaintiff's bonus claims is a distinct and separate question in the proceedings, which ought to be determined separately from the other issues in the proceedings (the bonus issue). In particular, that issue ought to be determined separately and subsequent to the determination of the plaintiff's entitlement to a bonus in the circumstances.
23 The bases for this submission that this should be separately determined are firstly, that the separate question may not be required to be determined, once the other issues in the proceedings are resolved; secondly, that if the separate question is required to be decided, the scope of the controversy will be reduced by the prior determination of other issues; thirdly, that determination of the separate question will require extensive and expensive discovery and court time, which will be avoided entirely if AMP is successful in other issues in the proceedings, and which will otherwise be substantially reduced; fourthly, that the separate question is a discrete question suitable for separate determination; and fifthly, that discovery addressed to the separate question will involve AMP disclosing information concerning bonuses paid to senior executives, which is commercially sensitive to AMP, and private to those individuals, in an industry in which such information is considered and treated as highly confidential.
24 On the estimate of AMP's solicitors, there are likely to be in excess of 3,000 documents falling into the categories of discovery currently pressed by the plaintiff as a result of his as yet un-particularised claim for bonus amounts. The information that the defendant will be required to discover on the separate question includes confidential information relating to individuals, and commercial information sensitive to the defendant. It will include information such as the bonus amounts awarded to individuals, which is personal, confidential, and commercially sensitive in an industry in which remuneration levels are the single most important factor in the competition for key staff. The procedure for the award of bonuses to the defendant's staff is also confidential and commercially sensitive. It will also involve discovery of the financial performance of the defendant and its related bodies corporate in the relevant financial years, and of the infrastructure division of which the plaintiff was a member.
25 I am not satisfied that the determination of all but the calculation of bonuses will substantially narrow the issues in dispute. The issue of bonuses and the plaintiff's entitlement will be relevant in the liability trial because these were, on the plaintiff's case, the subject of two oral representations made to the plaintiff by an employee of AMP, Mr Garling. AMP says that the discretion of AMP to pay bonuses is absolute and unfettered. Whether or not this is so is not beyond doubt - see Clark v BET plc [1997] IRLR 348. It is my view that there will be an overlap of discovered documents. Some documents will relate to both liability and quantum.
26 There will be an overlap of witnesses on the issues of liability and quantum but this overlap is confined to the plaintiff, Mr Garling and Mr Bryan. Messrs Garling and Bryan are employees of AMP. They are, in a sense, parties to the proceedings. I also accept that the separation of issues may shorten court time. AMP's case would take 10 days in total, five days if the bonus issue is determined separately. However, there is the possibility of two appeals.
27 The credibility of these witnesses, particularly that of the plaintiff and Mr Garling in my view will be critical to the outcome. This heavily mitigates against the separate determination of the bonus issue, particularly where the evidence concerning the oral representations will be of importance to liability and quantum.
28 AMP's concern about the discovery of commercially sensitive information are heightened by the fact that the plaintiff is now in direct competition with the defendant's infrastructure division. The plaintiff submitted that the concerns of AMP over commercially sensitive information have no foundation in fact but, in any event, can be met by an undertaking by the plaintiff, that the plaintiff is willing to give. I accept that the calculation of bonuses and information as to which employees received the larger bonuses are of a commercially sensitive nature. Undertakings given by the plaintiff and his legal representatives will not overcome the problem. That confidentiality will be lost when the evidence is given in Court. However, it may be that confidentiality can be protected by orders of the Court if the Court thinks that it is appropriate.
29 There are factors both in favour and against the separation of the bonus issue. Overall, it is my view that there is no bright line between the issues sought to be severed. It would be unwise to do so. There would be an overlap of issues. The application for a separate determination of issues ought not be granted. I dismiss the motion.
30 Costs are discretionary. Costs normally follow the event. The defendant is to pay the plaintiff's costs as agreed or assessed.
