purpose, or to a contract for the provision of credit for that object. Although Article 3 gives the parties a free choice of law, this choice cannot deprive the consumer of any protections available under the mandatory law of the country in which he has his habitual residence if the consumer was responding to advertising material or a specific invitation and makes the agreement in that country, or if the other party or his agent received the consumer's order in that country, or if the contract is for the sale of goods and the consumer travelled from that country to another country and there gave his order, provided that the consumer's journey was arranged by the seller for the purpose of inducing the consumer to buy. For these purposes, Article 7 defines "mandatory rules" as rules that must be applied whatever the Applicable Law. In deciding whether rules are mandatory in the lex fori or a law with which the contract has a close connection, regard shall be had to their nature and purpose and to the consequences of their application or non-application. If the contract is silent on the choice of law, it will be governed by the law of habitual residence if it is entered into in the circumstances described above. But this Article does not apply to: (a) a contract of carriage; (b) a contract for the supply of services where the services are to be supplied to the consumer exclusively in a country other than that in which he has his habitual residence. The Article does, however, apply to a contract which, for an inclusive price, provides for a combination of travel and accommodation. Contracts of employment Under Article 6, no choice of law selection contained in a contract of employment can deprive the employee of the protection afforded to him by the mandatory laws which would be applicable in the absence of that choice. If there is no express selection, an employment contract is governed, The provisions may only apply for the benefit of the employee. Material validity Under Article 8, the material validity of a contract, or of any term in a contract, shall be determined by the law which would govern it under the Convention if the contract or term were valid (i.e. the putative Applicable Law). But, if this would produce an obviously unfair result, a party may rely upon the law
