DBS BANK (HONG KONG) LIMITED v. LEGEND WORLD CORPORATION LTD AND ANOTHER

Citation

[2026] HKCFI 401
Court

Court of First Instance
Case number

HCMP70/2025

The court found credible triable issues — namely whether DBS Bank had given reasons for calling in the loans and whether DBS's alleged breach of bank-customer confidentiality caused CNAM to lose a major client such that the prevention principle could bar enforcement — and therefore the originating summonses could not be summarily determined; unconditional leave to defend was granted and the matters were converted to writs and consolidated.

DBS BANK (HONG KONG) LTD v. HONOUR ELITE CORPORATION LTD AND ANOTHER

Citation

[2026] HKCFI 401
Court

Court of First Instance
Case number

HCMP69/2025

The court found there are triable issues: (a) the plaintiff did not adequately explain reasons for exercising its right to demand immediate repayment, making the call-in arguable; and (b) there is an arguable prevention principle defence based on an alleged breach of banker-customer confidentiality that plausibly caused CNAM to lose a major client and precipitated inability to pay. Accordingly the originating summonses must be converted to writ actions, leave to defend is granted and consolidation is ordered to permit full adversarial resolution with pleadings and discovery.

DBS BANK (HONG KONG) LTD v. HAPPY GLOBAL INC LTD AND ANOTHER

Citation

[2026] HKCFI 401
Court

Court of First Instance
Case number

HCMP71/2025

The court held that the defendants raised sufficiently credible triable issues: (1) DBS Bank issued demands without identifying an Event of Default or explaining reasons for calling in instalment loans, making the validity of the demand arguable; and (2) there is an arguable breach of banker-customer confidentiality by DBS that may have caused CNAM to lose a major client with consequential inability to repay, invoking the prevention principle. Those triable factual issues require conversion of the originating summonses to writs and unconditional leave to defend.

DBS BANK (HONG KONG) LTD v. UNIVERSAL TALENT INC LTD AND ANOTHER

Citation

[2026] HKCFI 401
Court

Court of First Instance
Case number

HCMP72/2025

The court found credible, triable issues: DBS Bank failed to give reasons for demanding immediate repayment and there is an arguable breach of banker-customer confidentiality which could, on the evidence, have caused loss of a major client and consequent repayment failure; those issues are not suitable for summary determination under Order 88 and warrant conversion to writ and unconditional leave to defend.

FAN YIN WA v. LEUNG MEI YEE

Citation

[2023] HKDC 831
Court

District Court
Case number

DCMP2181/2023

The court granted the section 21 order limited to documents on or after 2 May 2022 because the applicant demonstrated a real prospect that the bank records are germane to tracing the HK$180,000 and the balance of privacy concerns favoured disclosure given the evidence of fraud and the bank’s neutral stance.

AISAN CORPORATION OF AMERICA AND ANOTHER v. UNKNOWN BANK ACCOUNT HOLDER(S) WITH DBS BANK (HONG KONG) LTD AND OTHERS

Citation

[2023] HKCFI 567
Court

Court of First Instance
Case number

HCA1661/2022

The court held that under section 21 Evidence Ordinance an ex parte order for inspection may be granted without service on unknown account holders if the applicant shows a probability that specified accounts contain materials germane to the issues; balancing privacy and banker-customer confidentiality justified a limited, supervised disclosure confined to specified accounts, account opening records, identities of authorised operators, contact details, statements and transfer particulars for a defined period, and rejecting open‑ended discovery to third tiers without further court application.

Citation

F.D.C. CO. LTD. AND ANOTHER v. THE CHASE MANHATTAN BANK, N.A.
Court

Court of Appeal
Case number

CACV65/1984

The Hong Kong bank owed an implied duty of confidentiality to its Hong Kong customers governed by Hong Kong law; the Tournier exceptions do not extend to permitting the bank to transfer documents located in Hong Kong to its head office abroad for the sole purpose of evading Hong Kong law and complying with a foreign court order; Hong Kong courts may enjoin such transfer and disclosure and, on the facts, the appeal to discharge the injunction was dismissed.

Citation

F.D.C. CO. LTD. AND ANOTHER v. THE CHASE MANHATTAN BANK, N.A.
Court

Court of Appeal
Case number

CACV131/1984

The Court held that under Hong Kong law the banker-customer contract includes an implied obligation of confidentiality protecting account information situated in Hong Kong; the compulsion-of-law exception in Tournier cannot be extended to orders of a foreign court compelling disclosure of documents located in Hong Kong. A Hong Kong branch is to be treated as distinct from its head office for this purpose; transfers designed solely to bring documents within a foreign court's jurisdiction may be restrained. Accordingly the injunction restraining disclosure and transfers was upheld and the bank'…

VANGUARD INTERNATIONAL MANUFACTURING LTD, INC v. THE CHASE MANHATTAN BANK N.A.

Citation

VANGUARD INTERNATIONAL MANUFACTURING LTD, INC v. THE CHASE MANHATTAN BANK N.A.
Court

Court of First Instance
Case number

HCA712/1984

Plaintiff demonstrated a serious issue to be tried and, on balance of convenience, would suffer serious and irreparable prejudice if interlocutory relief were refused because disclosure to the I.R.S. before trial would nullify the principal remedy; the Bank was not shown to be in real jeopardy of successful contempt sanctions in the US given availability of the foreign compulsion/good faith defence and the factual record, therefore interlocutory injunctions should be granted until trial or further order.

F.D.C. CO LTD v. THE CHASE MANHATTAN BANK N.A.

Citation

F.D.C. CO LTD v. THE CHASE MANHATTAN BANK N.A.
Court

Court of First Instance
Case number

HCA711/1984

The court granted interlocutory injunctions restraining the Bank from disclosing the plaintiffs' Hong Kong account information until trial or further order because the plaintiffs established a serious question to be tried under Hong Kong law, damages would be inadequate given the irreversible nature of disclosure, and on the evidence the Bank was not in real jeopardy of successful contempt sanctions in US courts owing to the availability of foreign compulsion/good faith defenses; accordingly the balance of convenience favoured the plaintiffs.
