The present study is part of such works, as it examines the connection between AI and criminal law. The presentation deals with AI-related general definition attempts and the main characteristics and a brief identification of the more frequent fields in application of AI. Furthermore, we will discuss most relevant issues from the aspect of criminal law (in a broader sense). The core of the talk is to identify the current substantive criminal legal matters regarding to AI. For example, the notions related to the subject of criminal liability, we present the relevant problems concerning the concept of a criminal offence and criminal sanction and the special part of the Act C of 2012 on the Criminal Code. Then we examine those cases where AI is an object of the offence. We do so in the hope that this work may not only inspire further scientific thinking but also may, perhaps, be used to serve as a support for future criminal legislation.
