The studies collected in this publication cover a wide range of topics in criminal law. Starting from fundamental issues of legal thinking methodology, they extend to significant and timeless doctrinal problems, such as: the principle of proportionality in the field of private law, including the annulment control of the principle, the capacity of law and its modern relationship with legal personality, issues of abuse of rights and institutions in civil and civil procedural law, the adversarial system and the duty of the court to guide the parties, the institution of desertion in political litigation, issues of evidence law, issues from the institution of the defendant's judicial and arbitral decisions, specific issues of compulsory execution, with emphasis on the problem of its abusive acceleration, issues of European procedural law, etc. A characteristic of the studies is that they approach institutions through their reduction to their historical and doctrinal foundations. This ensures a conscious critical approach to contemporary interpretive issues and assists not only the theoretical researcher but also the legal practitioner. The search for and utilization of the material in the volume is significantly facilitated through its analytical indexing.
