The recent era is characterized by business characterized by mass production, distribution and mass provision of services. In such an environment, companies conclude a large number of contracts in a short period of time, so it would be uneconomical for them to draw up a separate contract for each client and conduct negotiations for each individual team. Therefore, companies, in order to facilitate and speed up the conclusion of legal transactions, adopt their general terms of business, on the basis of which they regularly do business. Such a way of doing business brings numerous advantages, such as speeding up the conclusion of legal transactions and reducing costs, but it also entails certain negative effects. This is primarily where there is the possibility of abuse of consumers who in such a contractual relationship represent the weaker contracting party, given that it is a formal contract that is drawn up entirely by one contracting party (company) and often leaves no possibility for negotiation. In such a way of doing business, there is an increased need for consumer protection. At the level of the European Union, the Council Directive on unfair terms in consumer contracts was adopted, which governs that area. When Croatia joined the European Union, it had to implement and harmonize our legislation with the regulations of the European Union. Thus, our legislator decided to implement the provisions of this Directive in two national laws, the Law on Obligatory Relations and the Law on Consumer Protection. The laws regulate the field of general conditions in a very similar way, and both foresee nullity as the only consequence of unfair provisions. Both laws also stipulate that their provisions do not apply if the provisions of the general terms and conditions are taken from current regulations, if these provisions have been negotiated, and if they are about the subject matter and price, which are clear, comprehensible and easily observable. The difference between the laws is in the field of application and greater emphasis on negotiations in the Consumer Protection Act. As the field of consumer protection was a novelty both in the European Union and in national legislations, the need arose for the interpretation of numerous provisions of the Directive by the European Court in the form of previous questions. Therefore, this area, as a newer area of law, represents a great challenge for all national courts, as well as for Croatian courts, where the number of disputes in the field of consumer protection is increasing every day.
