Europe, Middle East and Africa Investigations Review 2020 Fighting corporate crime and compliance defence in the Czech Republic In summary Inspired the US Department of Justice’s (DOJ), non-binding internal guidelines for public prosecutors were issued in September 2018 (Czech CMS Guidelines). A slightly updated version of the Czech CMS Guidelines was published in November 2020. Both guides are comparable in quality and level of detail and a company will set-up an equally effective compliance management system following either of them. The major difference is the approach of the Czech prosecution authorities, which is considerably less predictable compared to DOJ’s. Czech prosecuting authorities are still struggling to understand the concept of compliance management systems and specially to apply it accordingly taking into account all the relevant specifics of the prosecuted company.
