Commissioner of Police v Channel Seven Adelaide Pty Ltd

Focus on:
- Appeal and new trial procedures in South Australia.
- Defamation law: discovery and interrogatories.

Appeal from a decision of a master in defamation proceedings ordering non-party discovery from the Commissioner of Police.

Whether the appeal should be evaluated based on material before the master at first instance or the material present during the appeal hearing.
Whether the master’s decision was premature, given a pending appeal regarding the first defendant's justification plea.
Concerns regarding the application amounting to a "fishing expedition" and the scope of discovery orders.

Held:
  - Appeal allowed in part to vary the form of orders made at first instance, otherwise dismissed.
  - Determined based on current circumstances not waiting for the resolution of the pleading appeal.
  - Noted a high likelihood that relevant documents are held by the Commissioner.
  - Orders framed to provide certainty, hence varied accordingly.

The plaintiff alleges defamation from Channel Seven due to its promotional content about his involvement in the murder case of Corrina Marr.
The promotion stated:
> "South Australian Federal MP, her boyfriend and the business trip – disgusted that taxpayer funds have been used – the paper trail and the whistleblower – he is a suspect in a murder case."
The complaint specifically concerns the words: "he is a suspect in a murder case."
Channel Seven asserted justification for its claims.

On 20 September 2007, Channel Seven sought an order requiring the Commissioner of Police to disclose documents related to the investigation.
Sought documents related to:
1. Interviews with the plaintiff regarding the Corrina Marr murder investigation.
2. Correspondence and witness statements concerning the plaintiff related to the murder investigation.
On 16 November 2007, the master partially granted the discovery but deferred further consideration of some parts.

Prematurity of Non-Party Discovery:
- Argues that the master should have adjourned consideration until all issues about Channel Seven’s justification were resolved.
Failure to Mitigate Damages:
- Claims that Channel Seven has no plea asserting the lack of reasonable steps taken by the plaintiff to mitigate losses.
Fishing Expedition Argument:
- Contends Channel Seven sought documents for improper purposes ("fishing expedition").

Challenges the master's decision made when the existing defence was not the final one.
Court is required to evaluate whether the decision was appropriate based on the current defence status at the time of appeal.

The Commissioner emphasized that engaging in discovery prematurely could divert crucial resources away from ongoing investigations.
Noted that significant delays had already arisen due to extensiveness of interlocutory disputes.

The Commissioner suggested that public interest immunity may apply to many documents sought from the police department.

The court determined that the principle of justification allows for non-party discovery to be appropriately sought by Channel Seven.
Justification must be adequately supported by relevant evidence directly related to the ongoing case.

Channel Seven's request for additional discovery was upheld partially, requiring only relevant documents pertaining to current justification claims without being overly burdensome to the Commissioner.
The order was framed to avoid oppression to the non-party while balancing justice interests.

The ruling emphasizes the careful consideration of case procedures in balancing defendants' rights, public interest, and efficiency in judicial processes.

Non-party discovery processes are essential but must be framed to respect the resources and privacy of those not party to the case while ensuring fair judicial proceedings.
Justification pleads need reasonable grounds, supported by evidence directly relevant to challenged statements, affording privacy considerations to non-parties.
