Nevertheless, Art. 6.3 DSA deals with liability exemptions and it is up to the Member States to decide when and under what conditions non-neutral platforms (those that have control or create the appearance of being the provider of the underliying service) should be liable for the seller’s non-performance. The following pages provide a comparison between the legislation and case law in Portugal and Spain, showing to what extent or under what circumstances these Member States acknowledge the contractual liability of a third party not involved in the contract between the trader and the consumer.13 p.application/pdfengcc-by (c) Arroyo Amayuelas, Esther, 2025http://creativecommons.org/licenses/by/4.0/Empreses de plataformes digitalsResponsabilitat (Dret)ConsumidorsMulti-sided platform businessesLiability (Law)Consumersinfo:eu-repo/semantics/bookPartinfo:eu-repo/semantics/openAccess
