Summary
This Court of Appeal decision concerns a marine insurance claim arising from the casualty of a jackup rig, “TERAS LYZA” (“Vessel”), during its maiden tow voyage from Vietnam to Taiwan. The insured (through the mortgagee, OCBC) sought to recover under a hull and machinery policy issued by multiple insurers. The central disputes were (i) whether the loss was caused by a “peril of the seas”, and (ii) whether the Vessel was a constructive total loss (“CTL”), such that the insured could treat the loss as effectively total and claim accordingly.
The Court of Appeal emphasised that the evidential framework for marine casualties cannot be treated as a convenient substitute for proof. While the law recognises a rebuttable presumption that a vessel’s loss is caused by perils of the sea where the vessel was seaworthy on sailing and the loss occurred in “wholly unexplained” circumstances, the presumption is not an evidential tool of convenience. Where a casualty is capable of explanation and the insured elects not to investigate, the presumption should not be invoked merely because the “wholly unexplained” condition cannot be satisfied.
On the facts, the Court of Appeal held that OCBC failed to discharge its burden to prove that the Vessel was lost by a peril of the seas. Further, OCBC also failed to establish that the Vessel was a CTL. The Court therefore reversed the High Court’s findings on both issues, notwithstanding that the High Court had ruled in favour of the insured even though no witness was called to prove CTL.
What Were the Facts of This Case?
OCBC was the mortgagee of the Vessel “TERAS LYZA”. Under a hull and machinery marine insurance policy (“MI”) issued by five insurers (the appellants), OCBC was a co-assured alongside the vessel owner, Teras Lyza Pte Ltd (“TLPL”), and the vessel manager, Teras Offshore Pte Ltd (“TOPL”). For ease of reference, the Court treated the owner and manager collectively as the “Teras Entities”, and where distinctions were not required, referred to them together with their parent company, Ezion Holdings Ltd (“Ezion”), as the “Owners”.
The MI was evidenced by a cover note issued by a marine insurance broker, LCH Lockton Pte Ltd, on 13 June 2017. The policy insured the hull and machinery up to an insured value of US$56m under Section [A]. There was also an “increased value and/or excess liabilities” component under Section [B], but the High Court found Section [B] void as a gaming or wagering contract; that finding was not challenged on appeal, leaving Section [A] as the operative coverage.
By Addendum No 1 dated 13 June 2017, the Teras Entities assigned their rights, title and interest in the MI to OCBC, which was named as the “sole loss payee”. A renewal certificate confirmed insurance for the period 1 August 2017 to 31 July 2018. The Vessel was then prepared for a tow voyage from Vung Tau, Vietnam to Taichung, Taiwan, intended as its maiden voyage for delivery to charterers. The insurers agreed to insure the Vessel for the tow voyage, formalised by Addendum No 3 (6 June 2018) and an endorsement to the renewal certificate (20 June 2018).
Operationally, the Owners conducted an internal feasibility study on wet towing, and ABS surveyor attendance resulted in various certificates and reports, including a Certificate of Fitness to Proceed under Tow and statutory survey reports. The Owners initially intended to engage Braemar as a marine warranty surveyor, but Techwise Offshore Consultancy was eventually appointed. Between 26 and 31 May 2018, Techwise issued multiple tow-related certificates and reports, including a Certificate of Fitness for Towage and a Suitability Survey Report. The Vessel departed on 30 May 2018 under tow by the tug “Teras Eden”. On 5 June 2018, the Vessel developed a list to port and trimming by the stern, and by 5.50pm it capsized.
What Were the Key Legal Issues?
The Court of Appeal identified two pivotal issues. First, whether OCBC proved that the loss was caused by a peril of the seas, and whether the rebuttable presumption of such causation could apply in the circumstances. This required the Court to consider the conditions for invoking the presumption, including whether the Vessel was seaworthy on sailing and whether the loss occurred in “wholly unexplained” circumstances.
Second, even if an insured peril were established (thereby engaging the marine insurance policy), the insured still had to prove that the Vessel was a constructive total loss (“CTL”). The Court therefore examined what evidence was required to establish CTL and whether OCBC had adduced admissible and sufficient proof, including whether documentary evidence could be relied upon as business records and whether any evidential or procedural defects could be cured.
Interwoven with these issues were evidentiary questions under the Evidence Act framework, including the admissibility of documents and the treatment of hearsay. The Court also addressed how the insured’s notice and fair presentation obligations interacted with the evidential record, and whether OCBC’s position on CTL was supported by proper proof rather than inference or assumption.
How Did the Court Analyse the Issues?
The Court began by situating the case within the broader logic of marine insurance and the law of evidence. It acknowledged the practical difficulty of proving the cause of a ship’s loss, particularly where a vessel sinks. The law therefore developed a rebuttable presumption that a loss is caused by perils of the sea if the insured can show that (i) the vessel was seaworthy on sailing and (ii) the loss occurred in “wholly unexplained” circumstances. The Court explained that this presumption reflects the “enormous difficulty” faced by shipowners in establishing the cause of sinking.
However, the Court stressed that the presumption is not a “tool of convenience”. The Court drew a sharp distinction between cases where the cause cannot be ascertained despite reasonable steps, and cases where the casualty is capable of being explained and the insured elects not to investigate. In such latter cases, the insured should not be permitted to invoke the presumption simply because the “wholly unexplained” condition is not met. The Court’s reasoning reflects a principled approach: the evidential burden shifts only when the factual prerequisites justify it.
Applying this framework, the Court of Appeal focused on the nature of the casualty. Unlike typical cases where the vessel sinks, the Vessel in this case did not sink. It capsized and remained afloat for weeks. During that period, the Vessel was inspected. Yet, on the Court’s account, no step was taken to investigate the cause of the capsize, and no evidence was adduced at trial that the cause could not have been ascertained. The Court treated this as decisive for the “wholly unexplained” requirement. Since the circumstances were not “wholly unexplained” in the legal sense—given the opportunity to investigate and the absence of evidence that investigation was impossible—the presumption could not be relied upon.
In addition, the Court held that OCBC did not propound a cause of the seawater ingress that would directly prove fortuity (ie, the fortuitous nature of the peril). The Court therefore concluded that OCBC failed to prove that the loss was caused by a peril of the seas. The Court’s analysis indicates that, even where the presumption is unavailable, the insured must still prove causation on the balance of probabilities, using admissible evidence and proper inferential reasoning where appropriate. The Court’s approach suggests that inferential reasoning cannot be used to paper over a failure to investigate where investigation was feasible.
On CTL, the Court of Appeal examined the evidential basis for treating the Vessel as a constructive total loss. The Court noted that CTL is not established merely by asserting that recovery or repair would be uneconomic; rather, it requires proof that the cost of recovery and/or repair would exceed the insured value of the vessel (subject to the statutory and contractual framework under the Marine Insurance Act 1906). The Court scrutinised the documentary materials relied upon by OCBC.
Specifically, the Court held that the CTL documents, save for certain reports (including the dive inspection report and SCRS reports), were not business records. This mattered because business records are often admitted as an exception to the hearsay rule, but only where statutory conditions are satisfied. The Court’s reasoning indicates that documents prepared for litigation purposes or not made in the ordinary course of trade or business cannot be treated as reliable substitutes for live testimony or proper evidential foundations. The Court therefore rejected the High Court’s approach that effectively allowed OCBC to rely on such documents without the necessary evidential safeguards.
The Court also addressed OCBC’s lack of notice pursuant to s 32(4)(b) of the Evidence Act. It held that this lack of notice should not have been cured by the Judge. This reflects the Court’s insistence on procedural fairness in the admission of evidence: parties must comply with notice requirements so that the opposing party can challenge admissibility and reliability. Where notice is absent, the court should not retrospectively “cure” the defect in a way that undermines the statutory scheme.
Further, the Court found that the CTL documents did not prove that the cost of recovery and/or repair exceeded the insured value of the Vessel. In other words, even if some documents were admissible, the evidential content was insufficient to meet the legal threshold for CTL. The Court also concluded that OCBC did not breach the warranties nor its duty of fair presentation, and that OCBC had proven indebtedness under the mortgage. These findings meant that the dispute was not about policy validity or the mortgagee’s standing to claim, but about whether the insured peril and CTL were properly proved.
What Was the Outcome?
The Court of Appeal allowed the insurers’ appeal. It reversed the High Court’s findings that OCBC had proved (i) that the loss was caused by perils of the seas and (ii) that the Vessel was a constructive total loss. The practical effect is that OCBC’s claim under the hull and machinery policy failed on the key substantive elements required to trigger and quantify recovery.
Although the Court accepted that OCBC had proven indebtedness under the mortgage and did not breach warranties or fair presentation, those points could not salvage the claim because the insured still had to establish causation and CTL on the evidence. The reversal therefore turned on proof and admissibility rather than on the broader validity of the insurance arrangement.
Why Does This Case Matter?
This decision is significant for marine insurance practice in Singapore because it clarifies the limits of the rebuttable presumption for perils of the sea. Practitioners often rely on the presumption in casualty cases, particularly where a vessel sinks. The Court of Appeal’s reasoning makes clear that the presumption is conditional and fact-sensitive: it requires seaworthiness on sailing and “wholly unexplained” circumstances. Where the vessel remains afloat for a period and investigation is feasible, the presumption should not be treated as automatic.
For insureds and their advisers, the case underscores the importance of immediate and contemporaneous investigation after a casualty. If the insured does not investigate when it can, the court may treat the circumstances as not “wholly unexplained” and require direct proof of causation. This is also a cautionary message about litigation strategy: documentary evidence and assumptions cannot replace the evidential foundations needed to satisfy the legal prerequisites for shifting burdens or invoking presumptions.
For insurers, the decision provides a robust evidential framework to challenge CTL claims. The Court’s approach to business records and notice under the Evidence Act highlights that admissibility and procedural compliance are not technicalities; they are essential to ensuring reliability. The case therefore has practical implications for how insurers respond to CTL claims, including scrutinising whether documents were made in the ordinary course of business and whether statutory notice requirements were met.
