PJB, Ex parte - Re Chisholm & Ors

This matter concerned an application by PJB, ex parte, before Heydon J in chambers. The application sought to set aside a subpoena issued by the respondents, Chisholm & Ors, directed to a third party, a Mr. G.

The central legal issue before the Court was whether the subpoena issued by the respondents was oppressive and should therefore be set aside. This required the Court to consider the principles governing the issuance and enforceability of subpoenas, particularly in circumstances where the subpoena sought documents from a non-party.

Heydon J applied the established principles regarding the setting aside of subpoenas. His Honour noted that a subpoena will be set aside if it is oppressive, which includes being unduly burdensome or an abuse of process. The Court considered the nature of the documents sought and the potential prejudice to the third party. His Honour found that the subpoena was indeed oppressive, as it sought a wide range of documents that were not sufficiently particularised and would impose an unreasonable burden on the third party to produce. The Court also considered the potential for the subpoena to be used for an improper purpose, such as to gain a forensic advantage in unrelated proceedings.

Consequently, Heydon J ordered that the subpoena issued by the respondents, Chisholm & Ors, directed to Mr. G be set aside.
