The purpose of this study was to show how the Penal Law protects sports in Greece against non-authentic and authentic sport crimes. A brief description of both categories is provided and the most important authentic sport crimes are discussed, as are the protection of the legal goods of the 'normal organization of the sport games' and the 'authenticity of the result of a game'. It is concluded that in the effort to find the best possible solution for the good of sport, the approach of the Greek legislature is very helpful.
