Citation: [2023] NSWSC 1446
Court: Supreme Court of New South Wales
Date: 7 August 2023
Judge(s): Rothman J
Background
This decision arose in an ongoing murder trial involving two accused. The Commissioner of Police brought a motion to set aside paragraph 6 of a subpoena that had been served on the Commissioner by short service. That paragraph sought production of material relating to statements or accounts provided by a Crown witness, referred to as Witness E, concerning the murder of the deceased.
The Commissioner argued that producing the documents would endanger the safety of Witness E, who had provided assistance to the Crown. Rothman J had already reviewed the documents in question without the parties having seen them, a process he acknowledged as procedurally awkward.
Legal Issues
- Whether the documents sought under paragraph 6 of the subpoena should be withheld on public interest immunity grounds due to the risk they posed to Witness E's safety
- Whether the documents were inculpatory, exculpatory, or relevant to the credit of Witness E under sections 55 and 56 of the Evidence Act 1995 (NSW)
- Whether the public interest in protecting the witness outweighed any forensic utility the documents might have for the accused
Decision
Issue 1: Public Interest Immunity and Witness Safety
Rothman J reviewed the documents in private and accepted the Commissioner's submission that disclosure could adversely affect the safety of Witness E (at [6]). The court confirmed that public interest immunity is not automatic but involves a balancing exercise, weighing the safety interest against the potential value of the documents to the accused (at [7]).
Issue 2: Probative or Forensic Value to the Accused
The court found that none of the material was inculpatory or exculpatory of the accused (at [7]). It also found the documents did not adversely affect Witness E's credit; if anything, they would marginally bolster the credibility of that witness (at [9]).
Issue 3: Balancing the Competing Interests
Taking the most favourable view possible from the accused's perspective, the court concluded the documents would not assist the accused in cross-examining Witness E or in presenting their case more broadly (at [11]). On that basis, the safety risk to Witness E was sufficient to sustain the public interest immunity claim, and production under paragraph 6 was set aside (at [11]).
Procedural Note on Further Documents
The court noted that additional documents likely fitting the subpoena description had not yet been located by the Commissioner. Rothman J directed that any such documents, once found, be produced to the court for separate ruling, acknowledging the outcome might differ depending on their content (at [10]).
Orders Made
- The Commissioner's claim of public interest immunity is upheld.
- The documents provided to the court need not be produced in answer to paragraph 6 of the subpoena.
Key Takeaways
- A public interest immunity claim based on witness safety requires a balancing exercise: the court must weigh the risk of harm to the witness against the forensic value the material might have for the accused (at [7]).
- Where documents are neither inculpatory nor exculpatory of the accused, and do not adversely affect the credit of the relevant witness, the scales tip more readily in favour of upholding immunity (at [7], [9]).
- Under sections 55 and 56 of the Evidence Act 1995 (NSW), the court assessed whether the documents could rationally affect the assessment of Witness E's credibility, finding they would not damage, and might marginally support, that credibility (at [9]).
- Rothman J observed that procedures allowing an independent, court-approved representative to review sensitive documents on behalf of accused persons, as sometimes used in terrorism matters, would be preferable to a process where accused persons have no visibility at all over withheld material (at [2]-[3]).
- A ruling on public interest immunity is document-specific: the court expressly reserved its position on further documents yet to be located, noting a different ruling could follow depending on their content (at [10]).
