Currently, the need to ensure that a decision is made based on results of forensic examination using the concept of decision rules is constantly increasing. Therefore, consideration of the issue of establishing rules for making decisions while forensic science activity at international and national levels is relevant. Relevance of this issue is justified not only by the requirements of ІSO/ IEC 17025:2017 for testing laboratories but by the requirements for the objectivity of expert opinion. ISO/IEC 17025:2017 recognizes that there is no single rule for deciding on conformity. In other words, in a specific situation there will be its own decision making rule. This also applies to forensic science activity.
 Therefore, this article purpose is necessary for forensic science activity to determine:
 
 general guidelines for choosing appropriate decision-making rule;
 directives for determining the components of decision making rules depending on the object and the task of forensic examination;
