The purpose of this study is to present the organization and functioning of the Institution of Representative of the Public Interest in Germany, which appear before  the Federal Administrative Court. This office, established in Leipzig, is a substitute for the General Counsel to the Republic of Poland. The main difference between these institutions lies in the fact that the Representative deals with the protection of the public interest and the General Counsel protects the interests of the State Treasury. The aim of the study is to present a fairly original concept of public interest and its protection in Germany. Such solutions are very rarely met. The work was written using dogmatic methodology and the analysis of institutional solutions. The result of this work is to show that the relatively small office of the Representative in Germany gives a fairly effective protection of the public interest in Germany. This solution can be recommended to be imitated in other European countries.
