This diploma thesis deals with the formation and development of the Public Prosecutors Office for Combatting Economic Crime and Corruption (abbreviation: WKStA). Its aim is to give an overview over this special office and to discuss it critically. First, I will illustrate the background and influences that contributed to the formation of the office. In this context, I will look into the various international and national standards, but also into the social changes related to economic crime and corruption cases. Furthermore, the various stages of development will be explained. Also, since the WKStA uses modern and innovative structures and tools, these will be described as well. The new tools, such as the BKMS® system and the innovative staff structure, will not only be explained, but also examined concerning their efficiency. Due to the fact that the WKStA is continuously growing and developing, this paper will also address potential for improvement as well as previous successes. A major part of this thesis deals with critical statements and issues concerning the WKStA. It is a prosecution body with special status that deals with large-scale economic crime and corruption cases. This is why directives and reporting represent especially sensitive topics, which this paper seeks to describe in more detail. I will not only analyze various points of criticism, but also look for possible problem solving approaches. Finally, the WKStAs milestone, namely its first branch office in Graz, will be discussed.
