I was surprised and struck by the fact that, after all the work carried out within the European Union (“EU”), on the subject of civil liability for Artificial Intelligence (“AI”) Systems, the European Commission has opted for a Directive (the Proposal for a Directive on adapting non contractual civil liability rules to artificial intelligence or “Proposal for a Directive”) as the instrument to regulate this issue. Moreover, a Directive with a content focused exclusively on two issues: a) the disclosure of relevant information for evidence purposes or to decide whether or not to bring forth a lawsuit and against whom (Article 3) and b) the presumption of the causal link between the defendant’s fault and the result or absence thereof that an AI system should produce (Article 4). The argument for this is the disparity of civil liability regimes in Europe and the difficulties there have always existed in harmonization (see the Explanatory Memorandum accompanying the Proposal, p. 7). Choosing a Regulation as proposed by the European Parliament[1] or the proposals of the White Paper on AI would have allowed such harmonisation, and could have included rules on evidence. It seems to me that behind this decision lies the invisible struggle, previously evidenced in other issues, between the Commission and the European Parliament. I believe that the risks for all involved in the use and handling of AI systems, especially high-risk ones, are compelling reasons in favour of harmonization and strict liability.

In relation to this aspect, the Proposal for a Directive abandons the risk-based approach that had been prevailing in this area, since it assumes that the civil liability regimes in most of the Member States are based on fault. This is referred to, for example, in Article 3(5) when presuming the breach of duty of care by the defendant or directly in Article 2(5) when defining the action for damages, or Article 4(1) when admitting the presumption of the causal link between it and the result produced by the IA system or by the absence or failure in the production of such a result which causes the damage. Therefore, if in the national civil liability regime, the case was subsumed under a strict liability regime (e.g., equated to the use or operation of a machine or vicarious liability of the employer), these rules would not apply. National procedural systems, in relation to access to evidence, are not so far r from the provisions of this future Directive.
