Consumer protection within the case law of the Court of Justice of the European Union

The term "average consumer" is relatively new and unknown. The aim of this thesis is to introduce the development of the concept and its usage within the case law of the Court of Justice of the European Union. I deal with definition of basic Czech terms as well as European terms in the first part of the thesis. Then I explain work and tasks of European courts. In the second part of the thesis I outline the most important cases which have changed the view of consumer and his behavior and perception during almost 40 years. This development through the case law has led to the creation of a new special term "average consumer". It is shown how this term is used in the area of consumer protection or protection of competition in the thesis
