In my graduation thesis I established a goal to discover most frequent unfair practises, which can come across a czech consumer. To accomplish this goal I've choosed following process. At first I made an enquiry between Organisations for consumer's protection and I visited frequently one of them. Also I get together all literary and virtual sources. Afterthan I made a part of Unfair practises in use, based on the informations from my enquiry and my visitation of Prague's office. In this part I tried to mention as many cosumer's problems as possible. Than I wanted to present possibilities of consumer's defence. Ther are two possibilities. The first is coming from civil law and it is included in the part of Judicature. The second possibility is from statutory law which is mentioned in the part of Activity of supervisor authority. When working on these practical parts I realised many possibilities how to make better the consumer's situation in Czech republic. These proposals I got into the final part of my work. At the end there was no more then to do theoretical or general part. This one was made on the basis of allready existing publications and articles. The real end was the introduction, where I highlighted my goal and I tried to mention problems included in my final thesis.
