It begins by defining gender-based violence and outlines relevant constitutional, international, and legal documents that regulate this field. Special emphasis is placed on the Constitution of the Republic of Croatia, international documents such as the Istanbul Convention, and national laws that ensure victim protection.

The process of filing and handling reports is analyzed, with a focus on protocols for domestic violence and sexual violence cases. Examples from court practice are presented, including special examination methods via audio-video links and the exclusion of the public from courtrooms.
