Criminal law as it’s traditionally seen is a set of standards defi ning socially harmful acts, referred to as crimes, determining the responsibility for these acts and the penalties, sanctions and protective measures applied against the perpetrators. More than any other branch of law, criminal law refl ects social attitudes towards specifi c cultural, moral and financial issues, demonstrating susceptibility to social changes, in principle denying its inter-culturalism, and exemplifying an extremely strong rooting in a specifi c culture. The concept of the European integration, together with ongoing globalization, have caused a shift in the way of thinking about the functioning of not only global society, countries or international institutions, but have also been changing the feeling of identity of individuals and their identification with a specifi c group or community. At the same time, the free fl ow of persons supporting the phenomenon of multi-culturalism, so characteristic for the concept of the European integration, has been determining the transnational nature of crime to a greater extent than before. This transnational character enforces, simultaneously, the development of the tools habitually designed for counteracting crime, including, first of all, traditionally understood criminal law. One example is the Erasure of Conviction in the Polish Criminal Law from the Perspective of the European Criminal Records Information System.
