Diplomatic bank account immunity required proper state assurances, not just a certificate.
Cross-motions arose out of enforcement proceedings on an ICC arbitration award against a foreign state, where the judgment creditor sought to garnish embassy-related bank accounts and the foreign state claimed diplomatic immunity.
The court held that a waiver of state immunity under the State Immunity Act did not amount to a complete waiver of diplomatic immunity, and that a certificate issued under the Foreign Missions and International Organizations Act could not itself confer immunity over bank accounts where the statute was silent.
Applying customary international law as incorporated into Canadian law, the court held that embassy and consular bank accounts are generally immune from attachment to the extent they are used for sovereign diplomatic or consular functions.
Because the evidentiary record lacked due assurances from a competent authority of the foreign state as to the purpose of the accounts, the court permitted further evidence and submissions.
