Without prejudice to Article 7(3), Member States may stipulate that the burden of proof in respect of the supplier's obligations to inform the consumer and the consumer's consent to conclusion of the contract and, where appropriate, its performance, can be placed on the supplier.
Any contractual term or condition providing that the burden of proof of the respect by the supplier of all or part of the obligations incumbent on him pursuant to this Directive should lie with the consumer shall be an unfair term within the meaning of Council Directive 93/13/EEC of 5 April 1993 on unfair terms in consumer contracts(1).
