||In September of 2009 the Law No. 395/2009 Coll. of significant market power in the sale of agricultural and food processing products and its abuse was adopted, which later came in force in 2010. Since the adoption the law is accompanied with problems, especially its very bad formal, as well as content imperfections. Thus complete abolishment of this legal standard was considered in year 2011. Following this act, it is proposed that the Act No. 143/2001 Coll. of protection of competition should be amended on those parts of law of significant market power, which proved to be beneficial for the competitive environment. Prior to the adoption of this amendment it is necessary to develop according to the directives of the European Union a Regulatory Impact Assessment, a document that analyzes the current situation, and through consultations with concerned individuals, propose possible solutions to the situation. In order to propose objective solutions, it is necessary to look into content and formal aspects of aborted law, find out the parts which have justifiable existence in the legislation, and after comparison with other European Union countries consider the form of criteria which will be assessed according to finding a distortion of competition. All this, if possible, with the lowest expenses and lowest possible impact on consumers.
