European Union – Consumer protection. Article 2(9) of Directive (EU) 2011/83 should be interpreted as meaning that a stand run by a trader at a trade fair, at which he carried out his activity for a few days each year, constituted 'business premises' within the meaning of that provision if, in the light of all the factual circumstances surrounding that activity, a reasonably well-informed and reasonably observant and circumspect consumer could reasonably assume that the trader was carrying out his activity there and would solicit him in order to conclude a contract, which was for the national court to ascertain. The Court of Justice of the European Union so held in a preliminary ruling in proceedings concerning information on the consumer's right of withdrawal in connection with a sale concluded at a trade fair.
