Evidence & proof

Evidence in product-liability investigations

Useful evidence links the product and its state to the alleged defect, the damage and the responsible actor. Preservation and explanation matter as much as collecting a large quantity of files.

Organise evidence by the question it answers

Separate identity and scope records, defect evidence, damage evidence, causal evidence and operator evidence. A test report may help with one issue while saying nothing about another. Record the proposition supported, provenance, date and limitations of each item.

Preserve originals and context

Keep original files and product records, document relevant versions and record who held physical items. An export should retain enough context to explain timestamps and configuration. These are practical investigation principles, not a claim that the Directive mandates one particular evidence system or retention period.

Plan access carefully

Evidence can include personal data, trade secrets and confidential technical information. Article 9 balances relevant disclosure with necessity, proportionality and protection of confidential information. An internal repository should distinguish preserved material from a disclosure set selected under legal guidance.

Records that help the review

Use the following as a practical starting point. Select and preserve records appropriate to the product, incident and applicable procedure.

  • Product identity and custody record
  • Versioned technical and incident records
  • Damage and causation evidence
  • Provenance, access and confidentiality notes

A complete repository is not a guarantee of a successful defence or compensation claim.
