(9)This Directive is without prejudice to individual actions brought by those who have been harmed by an unfair commercial practice. It is also without prejudice to Community and national rules on contract law, on intellectual property rights, on the health and safety aspects of products, on conditions of establishment and authorisation regimes, including those rules which, in conformity with Community law, relate to gambling activities, and to Community competition rules and the national provisions implementing them. The Member States will thus be able to retain or introduce restrictions and prohibitions of commercial practices on grounds of the protection of the health and safety of consumers in their territory wherever the trader is based, for example in relation to alcohol, tobacco or pharmaceuticals. Financial services and immovable property, by reason of their complexity and inherent serious risks, necessitate detailed requirements, including positive obligations on traders. For this reason, in the field of financial services and immovable property, this Directive is without prejudice to the right of Member States to go beyond its provisions to protect the economic interests of consumers. It is not appropriate to regulate here the certification and indication of the standard of fineness of articles of precious metal.
