Implementacja zasad ONZ dotyczących skutecznego przesłuchania i przesłuchiwania – perspektywy dla Polski i Litwy (COST Action CA22128: IMPLEMENDEZ)

Studies show that in criminal cases, most evidence is obtained through interviews and interrogations. Effective interviewing tactics, therefore, should be seen as an essential component of legal education, education and training of police officers and other law enforcement personnel. The Méndez Principles on effective interviewing and interrogation adopted in 2021 under the auspices of the United Nations offer an alternative to coercive, deceptive and confession-based interviewing and interrogation techniques. Grounded in extensive empirical and scientific research, the Principles promote rapport-based communication and the model of the investigative interview. In the article, the authors analyse these principles considering the existing legal framework and recommendations of European criminalistics. The primary objective is to identify the advantages of the implementation of the new model within the context of Polish and Lithuanian criminal proceedings. Potential challenges that might arise during the implementation process are also highlighted and analysed.
