Citation: R v Qaumi & Qaumi (No 7) [2016] NSWSC 1729
Court: Supreme Court of New South Wales
Date: 5 December 2016
Judge(s): Hamill J

Background

The decision arose in the course of a murder trial in which two accused faced charges relating to the killing of Joseph Antoun. During the trial, Hamill J had noted that evidence suggesting other people may have had a motive to kill the deceased was capable of bearing on the probability that the accused were involved in a joint criminal enterprise to commit the murder.

Following that observation, the NSW Crime Commission wrote to the Director of Public Prosecutions disclosing that it had received information from confidential human sources over the preceding week that included material about the murder of Joseph Antoun. The Commission flagged that it would raise a public interest immunity claim if further access to that material was sought.

The defence issued a subpoena to the Crime Commission seeking production of that material. The Commission responded with a formal public interest immunity claim, supported by both open and confidential affidavit material.

  • Whether the defence subpoena to the NSW Crime Commission disclosed a legitimate forensic purpose.
  • Whether the Crime Commission's public interest immunity claim was validly made.
  • How the public interest in maintaining confidentiality of human sources and ongoing investigations should be balanced against the accused's interest in a fair trial and the Crown's interest in access to relevant information.

Decision

Hamill J reviewed the confidential exhibits produced by the Crime Commission and was satisfied that the material was relevant to the trial. It touched on theories being advanced by the defence through cross-examination, including a case theory that a witness had been engaged to carry out the shooting on behalf of, or with, a third party who was himself later shot dead. The court accepted that the defence had a legitimate forensic purpose in seeking the material.

Despite finding relevance and legitimate forensic purpose, the court observed that the material, in its form and content, was unlikely to be admissible even if disclosed. It comprised opinions, assertions, and hearsay, limiting its probative value to the defence case.

Hamill J upheld the public interest immunity claim. The court accepted that disclosure risked identifying confidential human sources, jeopardising ongoing investigations, and endangering the safety of those sources. The court also noted that simple redaction of names would be insufficient, as the substance of the material could itself identify the informants.

On the balancing exercise, the court concluded that the public interest in maintaining confidentiality outweighed, by a fair margin, the desirability of disclosure to the parties. The relatively limited probative value of the material, given its inadmissible form, weighed significantly against production.

Orders Made

  • The NSW Crime Commission is excused from producing documents pursuant to paragraph 1 of the subpoena issued on 28 November 2016.

Key Takeaways

  • Hamill J confirmed that a three-step process applies where public interest immunity is claimed in response to a subpoena: the court must assess relevance and legitimate forensic purpose, determine whether the immunity claim is well-founded, and then conduct a balancing exercise if the claim is upheld.
  • A legitimate forensic purpose in seeking material does not, on its own, overcome a valid public interest immunity claim, particularly where the material is unlikely to be admissible in the proceedings.
  • Where disclosure of a document's substance, not just the names it contains, risks identifying confidential human sources, redaction will not cure the immunity concern.
  • The public interest in protecting human sources extends beyond individual safety: it encompasses the systemic value of maintaining the flow of confidential information to investigative bodies, which would be undermined if source identities could later be exposed through litigation.
  • In conducting the balancing exercise, the court took into account both the Crown's and the defence's respective case theories, as well as the form, content, and likely admissibility of the material sought.
