KMAN Publication Incorporation Interdisciplinary Studies in Society, Law, and Politics 3060-5687 In Press 2026 09 01 The Robustness of Judicial Rulings through Biometrics and the Principles Governing Its Probative Value The Robustness of Judicial Rulings through Biometrics and the Principles Governing Its Probative Value 1 10 EN Journal Article 2026 03 11 <p>One of the most effective strategies to counter the significant advancement of criminal activities alongside technological development is the modernization of crime detection methods. In this regard, biometric technology, as a knowledge-based tool, provides an advanced means for crime analysis, offender identification, the collection and documentation of criminal evidence, and the enhancement of judicial decision-making. By facilitating the acquisition of reliable evidence, biometrics contributes significantly to expediting judicial proceedings and promoting the issuance of well-founded and just judicial decisions. This study aims to elucidate how biometric evidence can legally and practically strengthen judicial rulings within the framework of Islamic jurisprudence. This study employs a descriptive-analytical approach based on library research to examine the role of biometric technology in strengthening judicial rulings. The findings indicate that, given the recognition of 'Ilm-e Qāḍī (Judicial Knowledge) as an independent means of proof in criminal proceedings and the growing application of biometric science in evidence gathering, the judge's Iqnāʿ-e Vojdānī (Inner Judicial Conviction) is formed through the interaction of two complementary elements. The first is the material element, consisting of the objective findings generated through biometric technology, which function as Amāreh-ye Qażā'ī (Judicial Presumptions) obtained through expert analysis. The second is the mental element, namely the judge's judicial knowledge arising from the evaluation of those findings. Together, these two elements provide a sound basis for the issuance of robust judicial rulings. For biometric evidence to possess probative value, however, its admissibility must satisfy the governing legal principles, including the lawful and voluntary acquisition of evidence free from coercion, the authenticity and legitimacy of the evidence, and its free judicial evaluation to ensure conformity with reality and to establish the judge's confidence.</p> https://www.journalisslp.com/index.php/isslp/article/download/543/1122
