Marketing Law constitutes that part of the legal system which regulates the conduct of business activities and the companies’ performance on the market. Broadly speaking, marketing law embraces general rules concerning establishment of companies, marketing and competition, as well as consumer protection. This branch of law lies at the intersection of public law and private law. It has a lot in common with the most vital areas of private law, such as contract law, tort law, as well as with intellectual property law. Teaching marketing law falls therefore within the compass of private law.

Two major areas form the core of marketing law: marketing practices law and competition law. Whereas the main concern of competition law is maintaining effective competition on the market and monitoring the markets’ structure, the main task of marketing practices law is promotion of fair competition in the interests of both consumers and businesses. Similarly to many other legal disciplines, marketing law has been strongly influenced by the European Union's integration efforts. There is a number of Community directives which focus on consumer protection based on different marketing methods (misleading advertisement, comparative advertising, distance agreements, electronic commerce, etc.). The influence of EU law has been even stronger in the field of competition law, whose development has been based on the principle of European integration. Studying the ongoing convergence of national laws and EU laws will therefore constitute one of the most thrilling subjects of research in the field.
