Findings, opinions and statements

Allegations are not findings. A commission's finding or opinion of corrupt conduct or misconduct is not a finding that a person is guilty of a criminal offence, and the commissions say so in their reports.

No findings are reproduced in this record. This does not establish that the report contains none.

Recommendations 3

  1. Recommendation 1

    Victoria Police reviews and amends the Victoria Police Manual (VPM) and its training to ensure police officers fully understand and comply with their obligations regarding evidence gathering and disclosure practices in investigations of criminal conduct, with a focus on statements and record keeping. The VPM and training should include the elements of proper practices in the making, taking and disclosure of a witness statement, and contemporaneous notes. These are highlighted in Figure 1 in section 1.2 of this report. Additionally, Victoria Police’s review should consider: a. the guidance and direction provided in other jurisdictions with a view to identifying other good practices b. officers’ obligations regarding evidence and disclosure under the Criminal Procedure Act c. how to most effectively communicate to all officers, including those who do not receive regular formal training, the obligations in recording evidence and the obligations of disclosure d. the role of supervising and senior officers in ensuring officers understand and comply with their evidentiary and disclosure obligations, and how this may be improved to address the concerns identified by Operation Gloucester e. how to achieve understanding by officers that non-compliance with the rules of evidence and the obligations of accurately recording and disclosing relevant evidence may affect the administration of justice and constitute misconduct or corruption.
