(25)In order to provide clarity as to what a consumer can expect from the goods and what the seller would be liable for in the event of failure to deliver what is expected, it is essential to fully harmonise rules for determining whether goods are in conformity. Any reference to conformity in this Directive should refer to conformity of the goods with the sales contract. In order to safeguard the legitimate interests of both parties to a sales contract, conformity should be assessed based on both subjective and objective requirements for conformity.
