International insurance case law: leading foreign decisions

By Dr Olavi-Jüri Luik, attorney at law (WIDEN)

Contents

In short. This overview brings together 95 insurance decisions of foreign courts that have shaped insurance law or matter in practice for construing international policy wordings. The decisions come from 13 countries: the United Kingdom, the United States, Canada, Australia, New Zealand, South Africa, Singapore, India, Germany, France, Finland, Sweden and Norway. They are grouped into 8 topics and listed chronologically within each topic. Each topic opens with a synthesis comparing the approaches of different legal systems and noting the link with Estonian law; the summaries are written in our own words and do not replace reading the decision.

Foreign decisions are not binding in Estonia. They apply their own law and the wording of the policy before the court. In Estonia they can supply arguments and interpretive options, but not legal rules. Before relying on a decision, check whether Estonian statute answers the question differently, whether the decision still represents the law of its jurisdiction and whether the policy in dispute is worded in the same way. A foreign decision carries more weight where the policy is governed by that country's law (for example in marine insurance, reinsurance and international programmes) or where the Estonian provision was modelled on the same legal system.

How to use this overview

  • Citation. Decisions are cited in the usual form of their jurisdiction: neutral citations in the United Kingdom and Commonwealth countries (for example [2021] UKSC 1 or 2016 SCC 37), official reporter citations in the United States, court, date and docket number in Germany, chamber, date and appeal number in France, and the court's official reference in the Nordic countries.
  • Paragraphs. Each entry shows the paragraphs (paras), pages (pp) or marginal numbers (Rn) reflected in the summary.
  • Verification. The court, date, citation and paragraphs of every decision were verified against the text of the decision on 8 November 2026. For one decision (BGH 18.12.2024, IV ZR 151/23) verification relies on the official headnotes and reprints; this is noted in the entry.
  • Links lead to the court's official website or an official database. Where no free official text was available, the link leads to a reprint (law.justia.com, caselaw.findlaw.com, scocal.stanford.edu) and this is indicated. Links for decisions of the German Federal Court of Justice lead to dejure.org, which collects the decision's details and references to its text.
  • Currency. Several decisions have since been modified by statute or developed in later case law (for example by the UK Insurance Act 2015). Later treatment should be checked before relying on a decision.
  • Link to Estonian law. References to Estonian law in the summaries and syntheses are our analytical conclusions.
  • Selection. The overview is not exhaustive. Leading decisions of higher courts and decisions frequently cited in international insurance practice are preferred; a few recent first or second instance decisions have been included because of their topicality.

Topics

The decisions are presented on 8 topic pages. Each page opens with a synthesis and then lists the decisions chronologically.

  1. War, cyber risk, causation and exclusions (10 decisions). These judgments show how courts identify the cause of loss and the reach of an exclusion where several factors contributed.
  2. Business interruption and pandemic risk (6 decisions). The COVID-19 pandemic exposed problems in interpreting business interruption extensions (notifiable disease, denial of access).
  3. Construction and property insurance: damage, design defects and reinstatement (12 decisions). These judgments address three questions.
  4. Liability insurance: duty to defend, defence costs and exclusions (17 decisions). In common law jurisdictions the central institution of liability insurance is the duty to defend, which is broader than the duty to indemnify: the insurer must defend where the claim may be covered (Gray, Montrose 1993, Progressive Homes) and, in a mixed action, may recover only defence costs unrelated to potentially covered claims (Buss).
  5. Limits, towers, aggregation and long-tail losses (14 decisions). Long-tail losses (pollution, asbestos, construction defects) raise two questions: which policy periods respond (trigger) and how the loss is allocated between policies.
  6. Notification, disclosure and time limits (12 decisions). These judgments deal with pre-contractual disclosure, the insurer's duty to inform and the consequences of notification failures.
  7. Good faith, fraud, fault and claims handling (14 decisions). In US and Canadian law the insurer's duty of good faith has developed into an independent liability: bad faith refusal to settle within limits or to pay benefits exposes the insurer to the whole loss, legal costs and, exceptionally, punitive damages (Comunale, Gruenberg, Brandt, Whiten, Fidler).
  8. Personal insurance and insurable interest (10 decisions). These judgments deal with the ordinary meaning of terms from the average policyholder's perspective (accident, illness, other insurance), beneficiaries' rights and the consequences of unpaid premiums (Gibbens, Sabean, BGH IV ZR 533/15, Discovery Life).
