The way of regulating criminal legal issues internationally has changed in recent decades, as an aftermath of increased intensity of globalization processes around the world combined with growth of transnational crime, and subsequent desire of the international community to co-operate on suppressing criminal conduct that transcends national frontiers. The vast majority of multilateral international treaties concluded overt the past decades have been devoted to transnational crimes, falling within the scope of transnational criminal law. One of such crimes, inevitably connected to the development and increased use of information and communication technologies, is grooming. The paper aims at presenting international regulations, provided for in a suppression convention, obliging the Polish legislator to penalize grooming in the domestic legal order, as well as the Polish domestic provisions complying with the said obligation.
