The Commercial Court’s decision in Malhotra Leisure Limited v Aviva Insurance Limited [2025] EWHC 2901 (Comm) establishes that properly pleaded and responsibly pursued fraud allegations can still attract indemnity costs where their objective weaknesses should have been apparent and they caused foreseeable harm.
Background
The case arose from a claim by Malhotra Leisure Limited against Aviva Insurance Limited concerning water damage to a hotel in July 2020. Aviva denied cover, alleging the escape of water was deliberate and formed part of a fraudulent conspiracy by the Malhotra principals to defraud the insurer. In the liability judgment ([2025] EWHC 1090 (Comm), 7 May 2025), the court rejected those allegations and found in favour of the Claimant. The subsequent costs judgment ([2025] EWHC 2901 (Comm), 6 November 2025) determined consequential costs matters following a July 2025 hearing.
Costs Issues Before the Court
The central issue was whether costs should be assessed on the indemnity or standard basis. This was significant because the Claimant’s actual costs of £1,202,957 were more than double its approved budget of £546,731. An indemnity costs order would render the budget irrelevant under CPR 3.18(a), whilst a standard basis order would require “good reason” to exceed it. The court also had to decide who should bear the costs of a specific disclosure application and the appropriate quantum of an interim payment on account (agreed at either £475,000 or £660,000 depending on the basis of assessment).
The Parties’ Positions
The Claimant argued that Aviva’s failed fraud allegations took the case “out of the norm” and warranted indemnity costs. It relied on Thakkar v Mican [2024] 1 WLR 4196, which confirmed that whilst there is no presumption, failed allegations of fraud will “very often” lead to indemnity costs. The Claimant submitted that Aviva’s fraud case was objectively weak from the outset, lacked proper evidential foundation for the alleged financial motive, and evolved at trial with unpleaded allegations. The Claimant highlighted significant financial and reputational harm suffered by its principals, including increased insurance costs, inability to obtain bank financing, and impacts on health and business relationships.
Aviva contended that costs should be assessed on the standard basis. It argued its fraud defence was properly pleaded, supported by credible lay and expert evidence, and pursued responsibly by experienced counsel. Aviva submitted the court must avoid hindsight and recognise the legitimate difficulties insurers face in challenging potentially fraudulent claims. The Defendant emphasised that insurers have a duty to challenge suspicious claims, as failing to do so adversely impacts all policyholders through higher premiums.
The Legal Framework
The court reaffirmed that indemnity costs are exceptional and awarded only where a case is “out of the norm.” An indemnity costs order is considerably more favourable than standard basis because it places the onus of showing costs are unreasonable on the paying party, disapplies proportionality, and renders approved budgets irrelevant. Failed fraud allegations often meet the “out of the norm” threshold, though there is no presumption. As the Court of Appeal stated in Thakkar v Mican, “what is sauce for the goose is sauce for the gander” – just as a dishonest claim attracts indemnity costs against a claimant, failed fraud allegations very often lead to indemnity costs against the defendant.
The Court’s Decision
Nigel Cooper KC, sitting as a Judge of the High Court, ordered that Aviva pay the Claimant’s costs on the indemnity basis. Critically, the judge accepted at [27] that Aviva’s allegations “were properly pleaded and pursued in an appropriate way” by experienced counsel. The court also acknowledged the case was supported by expert evidence and that there was evidence supporting the possibility of deliberate causation.
Nevertheless, the court concluded at [30] that “looking at the circumstances of the case overall an order for indemnity costs is appropriate.” The judge identified six specific factors justifying this conclusion:
-
-
- First, the exceptional seriousness of the allegations | The allegations were at the highest level – that three individuals had entered into a fraudulent conspiracy to damage property and defraud the insurer, supported by lies to both the insurer and the court.
- Second, foreseeable harm | The Claimant suffered financially (significantly increased insurance costs), Mr Meenu Malhotra was unable to obtain bank financing for developments, and both principals suffered reputational harm and impacts on health and business relations. These consequences were reasonably foreseeable, as evidenced by Aviva’s solicitors’ letter of 5 March 2021.
- Third, pursuit to the end | The allegations were pursued through to the end of trial without settlement discussions being pursued.
- Fourth, objective weakness apparent from the outset | The serious risks associated with Aviva’s allegations were, or should reasonably have been, apparent from when first raised. There was no direct evidence of deliberate causation. Aviva’s own expert initially considered the escape fortuitous and accepted in cross-examination that each required failure was plausibly capable of occurring fortuitously. Physical evidence was consistent with Tank 18 overspilling, yet none of Aviva’s proposed deliberate mechanisms involved this. The pleaded financial motive lacked proper evidential foundation – Aviva had early access to audited accounts and a screening report from its agent Sedgwick concluding the Malhotra Group was profitable and solvent with no signs of financial stress. The weakness of the motive case was apparent from an early stage, not only with hindsight.
- Fifth, evolving case at trial | Aviva’s motive case evolved at trial with new, unpleaded allegations concerning asbestos in the hotel and an alleged aim of constructing a sports bar. Neither was properly pleaded despite both requiring pleading. Both necessitated supplemental evidence and submissions. Both failed.
- Sixth, late withdrawal of specific allegations | Aviva pursued an allegation that Mr Malhotra was not celebrating his 60th birthday on the relevant night. The Claimant provided extensive disclosure in August 2021 and August 2022. The allegation was only dropped three weeks before trial, after the Claimant had procured witness statements from 10 individuals and obtained witness summonses for their attendance.
-
The court observed at [28] that Aviva was “determined to pursue this case through to trial,” as was apparent from counsel’s submissions. Despite the obvious difficulties and the serious risk of an indemnity costs order, Aviva chose to proceed.
The judge clarified at [17] that the effect of an indemnity costs order on costs management was “not a relevant circumstance” for deciding whether to make such an order. The disparity between budgeted and incurred costs did not itself justify indemnity costs.
On the specific disclosure application, the court made no order as to costs, meaning each party bore its own costs. The judge found it neither fruitful nor straightforward to determine what a contested hearing would have achieved given the parties’ cooperation in resolving the application.
Aviva was ordered to pay £660,000 on account of costs within 21 days, being the sum agreed as appropriate where costs are assessed on the indemnity basis.
Implications for Practice
This decision reinforces several important principles for costs practitioners and insurers:
-
-
- Proper pursuit does not insulate from indemnity costs | The court’s explicit acknowledgment that Aviva’s allegations were properly pleaded and pursued through experienced counsel demonstrates that technical compliance with pleading requirements and responsible litigation conduct does not prevent an indemnity costs order. The focus is on whether the overall circumstances take the case out of the norm.
- Objective assessment, not hindsight | Whilst courts must avoid hindsight bias, they will assess whether case weaknesses were or should have been apparent when allegations were first raised. Early availability of evidence undermining core elements (particularly motive) is highly relevant. Here, Aviva had access from an early stage to audited accounts and professional reports contradicting its financial motive theory.
- Foreseeable harm matters | Courts give weight to whether the consequences of serious fraud allegations – financial, reputational, and personal – were or should have been foreseeable. Solicitors’ correspondence acknowledging such consequences may be used against the alleging party in costs assessment.
- Aggressive pursuit includes refusing settlement | Pursuing allegations through to trial’s end without exploring settlement, combined with other factors, contributes to findings of aggressive pursuit warranting indemnity costs.
- Evolving theories require pleading | Introducing new aspects of case theory at trial (here, asbestos and sports bar allegations) that should have been pleaded supports indemnity costs awards, particularly where they necessitate supplemental evidence and submissions from the opposing party.
- Strategic withdrawal timing is scrutinised | Dropping specific allegations shortly before trial after the opposing party has incurred substantial costs responding (here, 10 witness statements and witness summonses) is relevant to assessing aggressive pursuit.
- Costs budgets become irrelevant | Once indemnity costs are awarded, approved budgets no longer constrain recovery under CPR 3.18(a). However, budget disparity alone does not justify indemnity costs.
-
For insurers, this decision serves as a clear warning: whilst entitled and sometimes duty-bound to investigate and defend potentially fraudulent claims, insurers must carefully assess the objective strength of fraud allegations before pursuing them through to trial. The duty to policyholders through maintaining premium levels does not override the costs risks of aggressively pursuing objectively weak fraud defences where core elements (particularly motive) lack proper evidential foundation from an early stage.
