Evidence mechanisms

Rebuttable presumptions

The new Directive uses presumptions to address particular evidential problems. Defectiveness and causation are separate issues, and the relevant presumptions are conditional and rebuttable.

Defectiveness routes

Article 10(2) addresses failure to disclose relevant evidence, non-compliance with mandatory safety requirements intended to protect against the damage risk, and an obvious malfunction in reasonably foreseeable use or ordinary circumstances. The factual basis for the selected route should be stated precisely.

Causation and technical complexity

Article 10(3) concerns damage typically consistent with an established defect. Article 10(4) addresses excessive technical or scientific difficulty, despite disclosure, with the specified likelihood requirement. Neither the presence of AI nor a complex product automatically establishes those conditions.

Allow for rebuttal

Article 10(5) expressly allows rebuttal. A sound evidence analysis records alternative mechanisms, testing limitations and disputed assumptions. It also avoids treating a presumed element as a final finding of liability, particularly where damage, scope or an exemption remains in dispute.

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.

  • Specific presumption and relevant paragraph
  • Facts satisfying each condition
  • Evidence of likelihood and technical difficulty
  • Rebuttal evidence and alternative explanations

A presumption can address a particular element. It does not automatically establish a final right to compensation.
