Operation Gloucester

IBAC held public examinations from 4 February to 1 March 2019 into alleged serious misconduct involving Victoria Police officers in relation to certain aspects of the investigation into the murders of Sergeant Gary Silk and Senior Constable Rodney Miller.

In November 2017, IBAC commenced an inquiry into police conduct in the Victoria Police investigation of the murders of Sergeant Gary Silk and Senior Constable Rodney Miller in 1998, following the receipt of new information. The investigation, known as Operation Gloucester progressed to public examinations.

The hearings were open to the public.

Public examinations

The examinations focused on:

  • the Lorimer task force investigation of the murders of Sergeant Gary Silk and Senior Constable Rodney Miller, concerning:
    1. the taking of witness statements
    2. the preparation of the brief of evidence for the trial of Bandali Debs and Jason Roberts (the trial)
    3. whether there was full disclosure of witness statements or other relevant information prior to or during the trial
  • witness statement taking practices by Victoria Police
  • compliance with the obligation to disclose evidence by Victoria Police.

IBAC Commissioner, The Honourable Robert Redlich QC presided at the examinations. Counsel assisting was Mr Jack Rush QC with Ms Catherine Boston of the Victorian Bar.

A special report on IBAC's Operation Gloucester is published on this website, along with Victoria Police's response to IBAC recommendations.

Overview of improper statement-taking practices identified

Improper statement-taking practices by Victoria Police identified during the hearings:

  • Omitting a witness’ description of an offender.
  • Omitting information which is contradicted by other evidence or is
    otherwise perceived by police to be unreliable.
  • Speaking to witnesses to ‘fix up inconsistencies’ in the evidence,
    and not disclosing that intervention.
  • Taking a replacement statement instead of a supplementary one.
  • Signing a back-dated statement.
  • Signing an acknowledgement in the absence of the statement
  • Making supposed ‘contemporaneous’ notes well after the fact.
  • Failing to disclose information which may assist the defence.

    Looking after the welfare of people involved in Operation Gloucester

    IBAC recognises our investigations and public hearings can place people under pressure. Supporting the welfare of people involved and subject to examination is a responsibility IBAC takes seriously.

    For the Operation Gloucester public hearings we provided witnesses with access to counselling services from the time their summons were served. When the hearings were in session, a professional counsellor and a private room was available. Witnesses were also able to bring a support person with them to the hearings.
