In the work "Introduction to Criminal Law - General Part", the basic concepts of Criminal Law are presented: the purpose of punishment and Criminal Law, the elements of crime in general, the elements of each crime, the interpretation of Criminal Law and the principle nullum crimen nulla poena sine lege, the distinctions of crimes and their practical significance, the grounds and persons to which Greek criminal law applies, the reasons for excluding criminal liability (exclusion of unlawfulness and imputation), the concept of intent and negligence, attempted crime, forms of participation in the crime, the accumulation of crimes, the penalties provided by the Criminal Code, the criteria for determining a just and appropriate punishment, the reasons for reducing the penalty, the suspension of the penalty, the conversion of the deprivation of liberty penalty, conditional discharge, special provisions for minors, and other related issues.

The abundant examples accompanying the theoretical concepts are intended to stimulate the reader's interest and contribute to their understanding and assimilation of the vague legal concepts, while also internalizing the related legal meanings, and at the same time constantly introducing them (mentally) to the grim reality and practice of criminal courts.

This is a comprehensive and user-friendly working aid for anyone involved in criminal law.
