Investigation Pack (ACAS-aligned)
PURPOSE
Create an ACAS-aligned investigation starter pack: invite wording, neutral question plan, and evidence log structure for transport incidents and potential misconduct.
WHEN TO USE
- âDraft an investigation invite letter for this incident and evidence list.â
- âCreate investigation questions for this driver interview, ACAS aligned.â
- âSummarise these incident notes into a clean manager brief.â (when it feeds an investigation)
DO NOT USE WHENâŚ
- Generic HR queries like âWhat is a fair disciplinary process?â with no case artefact needed.
- Youâre drafting outcomes/sanctions without an investigation stage.
INPUTS
- REQUIRED:
- Incident summary (what/when/where), parties involved, and whatâs alleged/being reviewed
- Evidence available so far (CCTV, telematics, tacho extracts, witness notes, PCN, photos)
- Proposed meeting date window and who will chair/note-take
- OPTIONAL:
- Relevant internal policies (paste text), previous similar cases, union/companion info
- EXAMPLES:
- âAllegation: falsified manual entry on [date]. Evidence: tacho report + supervisor note.â
OUTPUTS
investigation-invite.md(Word-ready)question-plan.mdevidence-log.md(Excel-ready table)- Success criteria:
- Neutral tone, no assumptions of guilt

WORKFLOW

- Build a neutral question plan using
assets/neutral-question-plan-template.md.- Start broad â then specifics â then mitigation/context â then closing.
- Create an evidence log using
assets/evidence-log-template.md.- Include chain-of-custody fields if needed.
- Add ACAS alignment checks from
references/acas-alignment-checklist.md. - If asked to edit existing documents â ASK FIRST.
