The situation

What has happened

The quarterly exhibit audit found that a cash exhibit from an August drug matter was recorded without a second member at the count and that a movement to the laboratory was not signed for by the receiving person. The matter is listed for a committal hearing in November and the defence has requested continuity statements. The Detective Senior Sergeant has directed a governance review: establish what happened, whether the Exhibit Handling and Continuity Procedure was followed, what the evidential consequences are, and what must change. The two members involved are available for interview. The investigation plan for the matter needs to be rewritten to close the gaps before the brief is served.

Your brief. Review the exhibit register entries and the procedure, interview the members involved fairly, establish the facts, assess the evidential and governance consequences, and produce a review report with corrective actions plus a revised investigation plan that restores continuity as far as it can be restored.

What to look for

Evidence guide

Evidence should show a factual timeline built from the register, interviews that are fair and recorded, a clear distinction between process failure and misconduct, and an honest assessment of what the court will be told. Corrective actions must have owners and dates. The revised investigation plan should be practical and should never involve altering or deleting the original register entries.

The student's evidence summary lists every record they created or changed in the systems named above, their notes and the tasks they ticked. Verify it against the deliverables and your own assessment tool.
