Paragraph 3 of the Statement of Claim defined "the Premises" as Unit 2. Though paragraph 7 of the Statement of Claim referred to a duty on the defendant to make good "any breakage defect or damage to the Building", the allegation of breach of that duty in paragraphs 8 and 9 spoke only of damages "to the Premises". But even if the Statement of Claim is to be read as extending beyond damage to Unit 2, the plaintiff was unable to say how much of the $121,696.74 claimed for demolition, site clearance and adjacent building repairs was for damage to Units 1 or 3, or for adjacent building repairs, and, even after the defendant denied there was material in the appeal papers going to that question, did not point to any.
32 In these circumstances the plaintiff advanced the following indignant pair of alternative submissions at the end of the oral argument:
"It would be remarkable and not to say wholly unjust, we submit, if a qualification or an excusing provision in a repair covenant limited to its own subject matter of repairing the premises let, somehow grew out of its own shoes and enlarged itself so gigantically as to exempt the person only obliged to repair the demised premises from any obligation at all to answer for damages for negligence going outside those premises. If your Honours are otherwise against us on everything else we have said in this appeal, your Honours must still recognise that your Honours are against us because of the application of a participle within the repair covenant in cl 5.1. And how can that clause outgrow its content to hold blameless the tenant when [its] negligent acts have financial consequences extending beyond the protection which the limited repair covenant confers upon it being limited as it is only to the premises, the subject of the demise. We submit, that would be such an unreasonable result as to call for first a serious inquiry, as to whether the repair covenant has that operation at all which is our preferred position. Secondly, at very least even if it does, to justify a new trial unless it's to the question of, what are damages not answered or what are the damages apart from the protection supplied by the repair covenant?"
33 So far as the request for a new trial made in the second part of that oral submission is concerned, this Court cannot order a new trial unless "some substantial wrong or miscarriage" has occurred: Supreme Court Rules Part 51 rule 23(1). The plaintiff had a complete opportunity to ventilate this question at the trial which has already taken place, and there is no wrong or miscarriage to be cured by a second trial.
34 The first part of the submission may have weight in the task of making a choice between methods of overcoming possible conflicts between clause 5.1 and clause 5.5.
35 One approach is to seek to avoid any conflict between clause 5.1 and clause 5.5 by treating clause 5.1 as dealing with claims for failure to keep Unit 2 in repair where the cause of the lack of repair is a fire or other catastrophe, while treating clause 5.5 as dealing with "any breakage defect or damage" caused otherwise than by fire or other catastrophe. This approach, which involves reading down the words "any breakage defect or damage", is perhaps less attractive, because it leaves the issue of breakages, defects or damage caused to Units 1 or 3 or to adjoining premises by negligently caused fires and other catastrophes unresolved. In short, it is exposed to the complaint made in the plaintiff's submission at the end of the oral argument.
36 A second possible mode of reading clause 5.1 and clause 5.5 minimises the plaintiff's reproach. That mode of construction would read clause 5.1 as giving the Lessee immunity from action for damage caused by fire and other catastrophes to Unit 2 (unless any insurance monies were irrecoverable by the Lessee's neglect), while treating clause 5.5 as applying in relation to damage caused by fire and other catastrophes, and otherwise caused, for damage to Units 1, 3 and adjoining premises. Clause 5.1 deals with the specific subject of damage caused to Unit 2 by fire and other catastrophes; clause 5.5 with the general subject of damage caused by fire and other catastrophes and otherwise; the specific provision prevails over the general one. Another, more mechanical, rule of construction which achieves the same result is that if a clause in a contract is followed by a later clause which destroys the effect of the first clause, the latter clause is to be rejected as repugnant and the earlier clause prevails; but if a later clause can be read as qualifying rather than destroying the effect of the earlier clause, then the two are to be read together, and effect given to both. See K Lewison The Interpretation of Contracts (2nd ed, London, Sweet & Maxwell, 1997) para 8-08. On that principle a wide construction of clause 5.5 is to be rejected, but only to the extent of the repugnancy. It is to be rejected to the extent that it would make the Lessee liable for damage caused by fire and other catastrophes to Unit 2, being a form of damage which clause 5.1 rendered the Lessee immune from liability for. The construction arrived at by these means appears sound. On that basis the defendant would be able to resist the plaintiff's claim under clause 5.5 so far as it rested on damage to Unit 2, but not otherwise. However, since neither the Statement of Claim nor the evidence identified what the relevant quantum referable to damage otherwise than to Unit 2 was, the plaintiff wholly fails.
37 The plaintiff's contention that its right to sue the defendant at common law in negligence was unaffected by clause 5.1 encounters difficulties which are similar to those raised by its reliance on clause 5.5. The Lessee is only liable under clause 5.1 for failure to maintain the premises in respect of structural maintenance replacement or repair "when the same is rendered necessary by" inter alia any neglect or default on the Lessee's part. To that liability and negligence clause 5.1 creates a defence in relation to fires or other catastrophes where it is not the case that any insurance monies are irrecoverable through the Lessee's neglect. If clause 5.1 creates a defence for negligently caused fires, why should the device of suing, not under clause 5.1, but in the tort of negligence, permit the Lessor to recover for the conduct in tort in a manner it cannot recover for in contract?
38 There is a further difficulty in the plaintiff's contention that even where it is debarred from recovery under clause 5.1 it can recover under clause 5.5 or in negligence. The plain effect of clause 5.1 is that where the Lessor has recovered insurance monies for losses caused by catastrophic fires which were the result of the Lessee's conduct (including the Lessee's fault), the Lessor is not to recover any monies from the Lessee. Clause 5.1 contemplates single recovery through the insurance monies where they are recoverable. It rules out double recovery, whether by the Lessor's direct action against the Lessee or by an insurer of the Lessor pursuing a subrogated claim against the Lessee. Yet to permit recovery under clause 5.5 or in negligence would generate the double recovery against which clause 5.1 set its face.
