This codex is a comprehensive collection of important legislative documents relevant to the field of European business law. It is specifically designed for students enrolled in the Business Law I course at the Vrije Universiteit Brussel, as part of the Business Economics program. Therefore, it includes only those legislative texts and excerpts that are directly or indirectly related to the course material. Nevertheless, this codex also serves as a valuable reference for anyone engaged in business within the European Union. The codex includes legislative updates until 1 July 2024.
