Federal Court: Australian Privilege Covers Japanese Legal Advice

• The Federal Court of Australia ruled that Australian legal professional privilege protects Japanese legal advice, even though Japan lacks an equivalent doctrine.
• The decision in White Oak Commercial Finance Europe v Insurance Australia Ltd dismissed an application to obtain an unredacted Japanese legal report.
• The court found that Australian law governed the privilege claim, citing Rule 20.02 of the Federal Court Rules 2011.
• Disclosure of a confidential update based on the report to Japan's Financial Services Agency did not waive privilege, as officials were bound by statutory confidentiality.
• The report's dominant purpose was determined to be legal advice on Tokio Marine Holdings' obligations under Japanese law.

This ruling underscores the broad application of Australian privilege law in cross-border disputes.

The Federal Court of Australia recently issued a significant decision affirming that Australian legal professional privilege can extend to legal advice obtained from foreign jurisdictions, even those without an equivalent doctrine. In the case of White Oak Commercial Finance Europe (Non-Levered) Ltd v Insurance Australia Ltd (Japanese Privilege) [2026] FCA 1475, the court dismissed an application by White Oak Commercial Finance Europe (Non-Levered) Limited, which sought the unredacted production of a Japanese legal report. This ruling underscores the broad application of Australian privilege law in cross-border disputes.

The contested document was a report dated December 11, 2020, prepared by the Japanese law firm Mori Hamada & Matsumoto (MHM). This report was commissioned by Tokio Marine Holdings, Inc (TMHD), the ultimate Japanese parent company of BCC Trade Credit Pty. Ltd., to provide Tokio Marine legal advice privilege concerning potential breaches of Japanese laws and regulatory standards. The advice was sought in connection with investigations into Greg Brereton, BCC's former Head of Trade Credit, who was suspected of issuing trade credit insurance policies beyond his authorized limits. White Oak had sought this report from BCC Trade Credit Pty. Ltd. and two Tokio Marine entities.

White Oak contended that Japanese law should govern the determination of privilege, arguing that since Japan does not formally recognize a doctrine of legal professional privilege, the report should be produced without redaction. The Federal Court, however, rejected this argument, asserting that Australian law applied to the privilege claim. The court referenced Rule 20.02 of the Federal Court Rules 2011, which specifically refers to privileges recognized under Australian law, thereby establishing that no choice of law issue arose given the dispute concerned immunity from compulsory production under Australian discovery procedures. Furthermore, the court noted that even if a choice-of-law question were to arise, consistent with established authorities, the law of the forum would apply to such privilege disputes.

The court also addressed White Oak's assertion that the MHM report primarily constituted a factual investigation rather than legal advice. The Federal Court found that the dominant purpose of the report was to communicate legal advice regarding TMHD's obligations under Japanese law, with the investigative work serving as an integral part of preparing that advice. Expert evidence presented to the court confirmed that Japanese law does protect confidential lawyer-client communications through professional confidentiality obligations and restrictions on compulsory document production. The court further determined that all eight discovered copies of the report were independently privileged, having been created for the purpose of obtaining legal advice or for litigation.

A key argument advanced by White Oak was that TMHD and Tokio Marine & Nichido Fire Insurance Co Ltd had waived privilege by disclosing information to Japan's Financial Services Agency (FSA). This argument centered on the idea that any disclosure, even to a regulator, could undermine the confidentiality essential for maintaining privilege. However, the Federal Court meticulously examined the nature of this disclosure.

The court found that the companies had provided only a confidential update to the FSA, which was based on the report, rather than disclosing the report itself. Crucially, the court also noted that officials at the Japanese Financial Services Agency were bound by statutory confidentiality obligations. Consequently, the court concluded that this limited regulatory disclosure did not undermine the confidentiality of the report nor did it constitute a waiver of privilege. This aspect of the ruling provides important clarification on waiver of privilege regulatory disclosure in a multinational context.

The Federal Court's decision in White Oak v Insurance Australia privilege provides significant clarity for multinational corporations operating in Australia and engaging with foreign legal systems. It firmly establishes that Australian legal professional privilege can protect legal advice obtained from foreign counsel, even when that foreign jurisdiction, such as Japan, does not possess an identical privilege doctrine. This means that companies like Tokio Marine can confidently seek legal advice from Japanese firms, knowing that this advice may be protected under Australian law if a dispute arises in an Australian court.

The ruling also offers crucial guidance on the boundaries of waiving privilege through regulatory interactions. By confirming that a confidential update to a foreign regulator, where the regulator is also bound by confidentiality, does not automatically waive privilege, the court has provided a measure of assurance for companies navigating complex international regulatory landscapes. This reinforces the principle that careful management of disclosures, particularly in the context of legal professional privilege Australia Japan, is vital for maintaining the integrity of privileged communications.

This ruling clarifies that Australian legal professional privilege can protect foreign legal advice, even from jurisdictions like Japan without an equivalent doctrine, and that limited, confidential disclosures to foreign regulators may not constitute a waiver. Lawyers must understand these principles when advising multinational clients on cross-border legal advice and regulatory interactions to ensure privilege is maintained.
