Abstract

The study aims to analyze the legal gaps related to the regulation of new types of narcotics that have not been registered. This research employs a normative legal research method, which focuses on analyzing the existing legal provisions as stated in the relevant laws and regulations. The purpose is to examine how these legal frameworks address the emergence of new types of narcotics, especially those not yet registered in Indonesia. With the rapid development of synthetic drugs and other new narcotic substances, existing laws often struggle to keep up with emerging challenges. The normative legal research approach is particularly suitable for this study because it enables a critical examination of how the current legal system responds to these developments and whether it provides adequate legal tools to address such issues. Through this approach, the study will explore the gaps in existing positive law and assess how these legal voids impact the implementation of anti-drug policies and law enforcement in Indonesia. One key issue identified is the inability of current narcotics laws to effectively regulate or prevent the circulation of new, unregistered substances. This lack of legal recognition creates challenges for law enforcement agencies in controlling the distribution and use of such narcotics. Furthermore, the study will analyze the implications of these legal gaps on public health, law enforcement practices, and the overall effectiveness of anti-drug efforts in Indonesia. By identifying the shortcomings in the regulation of new narcotics types, the research aims to provide recommendations for improving legal frameworks and ensuring that laws evolve in tandem with emerging drug trends. Ultimately, this study contributes to enhancing the legal response to narcotic-related issues and supports the development of more effective drug control policies in Indonesia.

Abstract

This study examines the role and challenges of evidence management in the criminal justice system in Indonesia, focusing on issues such as damage, loss, and inconsistency of evidence, which can significantly impact the evidentiary process and the outcome of criminal trials. Effective evidence management is crucial in ensuring the integrity of the legal process and upholding justice. The study employs a normative legal approach using statutory and conceptual methods to analyze the legal provisions that govern the confiscation, storage, and handling of evidence, specifically referring to Article 39 of the Indonesian Criminal Procedure Code. This article sets forth the procedures for evidence confiscation by law enforcement authorities and outlines their responsibilities in maintaining and presenting the evidence in court. A major concern in the management of evidence is the potential damage or loss of evidence during the investigation or trial stages. Such issues undermine the validity of the evidence and can lead to unjust verdicts, affecting the principle of fairness in the criminal justice process. Additionally, inconsistencies in how evidence is handled, including mislabeling or failure to maintain chain-of-custody records, can raise doubts about the authenticity of the evidence and erode public trust in the legal system. This study highlights how these problems directly impact the judicial outcomes and the overall credibility of the justice system in Indonesia. Furthermore, this study discusses the challenges faced by law enforcement agencies and legal professionals in returning evidence that does not conform to its original condition. The return of damaged or improperly handled evidence not only violates the principle of justice but also affects the accused's right to a fair trial.
