Abstract
This research aims to demonstrate the role of the principles of criminal psychology in achieving justice in Palestine, by presenting these principles as theories and rules that contribute to achieving justice during investigation, trial, or execution of sentences, which is reflected through the practical application of these principles by the competent authority, or through the inclusion of them in laws and legislation.
The importance of these principles has created a need to study their role in achieving criminal justice, specifically by answering the question: How do the principles of Palestinian forensic psychology contribute to achieving justice?
To answer the question, the researchers employed a descriptive approach, incorporating qualitative and content analysis aspects of psychology, as well as its impact from a legislative and judicial perspective. Additionally, an analytical approach was used to analyze relevant legal texts and a group of court decisions.
The research reached important conclusions. The Palestinian criminal policy is informed by the principles of criminal psychology, which are enshrined in all stages of the criminal case, from gathering evidence to the mechanisms for implementing judicial rulings. The study also presented a set of recommendations, the most important of which is the need to enshrine the concepts and principles of criminal psychology through judicial rulings issued by courts of different levels, in order to establish a clear and approved concept of the principles of psychology linked to the latest theories on which it is based. Likewise, to conduct training courses related to the principles of criminal psychology and the necessity of integrating them into legal and judicial work, from which all arms of justice benefit, with a focus on judicial officers, the public prosecution, and judges.
