Attorney General in and for the State of New South Wales

The case involved the Attorney General for the State of New South Wales, acting on behalf of the State of Poland, and Westpac Banking Corporation. The Polish authorities sought evidence relating to a bank account held by a deceased individual, which was located in New South Wales. The court was required to determine whether the requested evidence should be disclosed and, if so, the appropriate legal mechanisms to facilitate the disclosure. The legal issues centred around the admissibility and relevance of the evidence, as well as the procedural requirements for obtaining such evidence from a bank in Australia.

The court considered whether the evidence was relevant to the proceedings in Poland and whether it could be disclosed under the mutual legal assistance treaty between Australia and Poland. The court also examined the procedural aspects of subpoenaing a bank to produce documents and whether the evidence could be obtained without undue hardship or prejudice. Ultimately, the court found that the evidence was relevant and could be disclosed under the treaty provisions. The court issued orders for a subpoena to be served on Westpac Banking Corporation to produce the requested documents and for an affidavit to be sworn by an officer of the bank.

In making these orders, the court took into account the balance of convenience, the rights of the deceased's estate, and the obligations under the mutual legal assistance treaty. The court concluded that the disclosure of the evidence was necessary in the interest of justice and that the procedural steps outlined would facilitate the disclosure without causing undue hardship. The court emphasised the importance of international cooperation in legal matters and the role of domestic courts in facilitating such cooperation.

The final orders included a directive for Westpac Banking Corporation to produce the requested documents and for an affidavit to be sworn by an officer of the bank. The court also made orders for the service of the subpoena and for any necessary protective measures to be taken to safeguard the rights of the parties involved. The court's decision underscores the importance of adhering to international legal obligations and the role of domestic courts in ensuring the effective exchange of evidence between jurisdictions.
