Factual and Procedural Background
This appeal arises from a judgment delivered on 8 October 2024 by Madam Justice McBride concerning contested discovery applications in a commercial dispute. The Plaintiff, a manufacturer of aircraft parts and structures, entered into a procurement contract in 2009 with a subsidiary of the Defendant, a holding company. The contract involved the design, manufacture, and supply of flap track fairings (FTFs) for aircraft. The Defendant executed a performance guarantee securing the subsidiary’s obligations under the contract.
In June 2020, the subsidiary sold its assets to a third party, who novated the procurement contract and was supported by a new guarantee from the Defendant. The Plaintiff alleges that the third party failed to deliver conforming products from April 2021 onwards, resulting in significant financial losses. The third party subsequently filed for bankruptcy and sought to reject the contract.
The Plaintiff requested indemnification from the Defendant under the guarantee, which the Defendant declined. The Plaintiff mitigated losses by entering into agreements with the third party and relocating production. The Defendant contests liability, arguing that material variations to the contract and commercial circumstances discharged its guarantee obligations. The discovery dispute focuses on whether relevant documents relating to these changes and the Defendant’s liability should be disclosed.
The appeal challenges the trial judge’s order on discovery, mainly concerning the relevance of documents related to the procurement contract and guarantee, particularly for periods before and after the 2020 novation.
Legal Issues Presented
- Whether the Defendant has discharged its burden of establishing that the documents sought in discovery relate to a matter in question between the parties.
- Whether amendments or variations to the procurement contract prior to the 2020 guarantee discharge the Defendant from liability under that guarantee.
- The proper construction and interpretation of the guarantee and its relationship to the underlying procurement contract.
- The scope and limits of discovery in relation to material changes in contractual and commercial circumstances affecting the Defendant’s liability.
Arguments of the Parties
Appellant's Arguments
- The Defendant contends that the guarantee’s obligations are limited to the minimum production requirements under the procurement contract and not to the broader losses claimed by the Plaintiff.
- Material variations and changes in ownership and supply arrangements between 2009 and 2022 materially altered the basis of the guarantee, discharging the Defendant from liability.
- The Defendant lacks access to relevant documents due to divestment of the business unit in 2020 and limited involvement in contractual events, justifying a broad discovery order.
- The Defendant emphasizes the need to understand the evolving contractual obligations and trading relationships to assess its exposure under the guarantee.
- The Defendant argues that discovery affidavits sufficiently establish a prima facie case for discovery under Order 24, Rule 7.
Respondent's Arguments
- The Plaintiff submits that the procurement contract was only formally amended by three written amendments and denies that informal or conduct-based amendments bind the parties.
- The Plaintiff argues that the Defendant’s discovery requests related to alleged informal amendments are speculative and amount to a fishing expedition without proper pleading.
- The Plaintiff maintains that the Defendant’s liability under the guarantee is not discharged by any pre-2020 amendments and that the guarantee covers the obligations of the third party under the novated contract.
- The Plaintiff disputes the Defendant’s claims regarding remoteness of damage, stating no such defence is pleaded or viable.
- The Plaintiff asserts that discovery should be limited to documents relevant to the period after the 2020 novation, consistent with the judge’s order.

Court's Reasoning and Analysis
The court applied the well-established principle that appellate interference with a judge’s discretionary interlocutory order requires a showing of error in law, disregard of principle, or a decision outside the bounds of reasonable disagreement. The parties did not contest this principle.
The court examined the factual and contractual framework, including the 2009 procurement contract, the 2020 novation, and the guarantees provided by the Defendant. The Plaintiff’s claim is founded on the Defendant’s guarantee of the third party’s performance, alleging significant losses due to breach.
The court analysed the pleadings, finding that the Defendant’s defence is that material contractual and commercial changes discharged its guarantee obligations or limited its liability to minimum production requirements. The Defendant also sought discovery of documents to support this defence, asserting limited knowledge and access to relevant documents due to divestment of the business unit.
The court considered the discovery summons and supporting affidavits. It found that the affidavits lacked the necessary evidential foundation for an Order 24, Rule 7 discovery application, containing impermissible argument and lacking direct knowledge or statements of belief with sources. Notably, no affidavit from a Defendant officer or employee was provided.
The court emphasised the burden on the moving party to establish that the documents sought are both in the other party’s possession and relevant to a matter in question. It found the Defendant’s discovery request to be vague, speculative, and insufficiently grounded.
Regarding the Defendant’s argument on remoteness of damage, the court noted the absence of any pleaded remoteness defence and no viable submissions to that effect. The Plaintiff’s claim for damages is based on the first limb of the Hadley v Baxendale rule, focusing on losses naturally arising from the breach.
The court upheld the trial judge’s construction of the contractual instruments, rejecting the Defendant’s claim that pre-2020 amendments discharged liability. It noted that interpretation of contract provisions is a question of law and found no error in the judge’s reasoning.
Ultimately, the court concluded that the Defendant failed to meet the threshold for extending discovery beyond the order made by the trial judge and dismissed the appeal.
Holding and Implications
The court DISMISSED THE APPEAL and affirmed the decision of the trial judge. The Defendant’s application for further discovery was refused due to lack of sufficient evidential foundation and relevance.
The direct effect is that discovery will proceed as ordered by the trial judge, limiting the Defendant’s access to documents primarily concerning the period post-2020 novation. No new precedent was established; the decision reinforces established principles governing appellate review of discretionary interlocutory orders and the evidential requirements for discovery applications.
