Claims & proof

Burden of proof

Article 10(1) requires the claimant to prove defectiveness, damage and the causal link. The Directive also provides conditional presumptions that can assist with specified elements.

Keep the three elements distinct

Evidence of a product failure is not automatically evidence of the claimed damage, and evidence of damage is not automatically evidence of a safety defect. State each element separately and identify the material that supports it. This makes gaps and disputed assumptions easier to see.

Presumptions have conditions

Article 10 includes circumstances concerning failure to disclose, relevant safety non-compliance, obvious malfunction, typically consistent harm and excessive technical or scientific difficulty. Each route has its own conditions. A party should identify the particular provision relied on and the facts said to meet it.

The presumption remains rebuttable

Article 10(5) permits defendants to rebut the presumptions. Evidence may address whether the alleged defect existed, whether it caused the damage or whether another explanation is supported. A presumption does not amount to a final judicial determination of every issue in a claim.

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.

  • Evidence of the alleged safety defect
  • Evidence of the damage category and loss
  • Mechanism connecting defect and harm
  • Facts supporting or rebutting a specific presumption

No-fault liability does not mean no proof is required.
