The Limits and Strengths of Forensic Laboratory Evidence in Proving Document Forgery

Abstract

Judicial proof requires judges to assess all forms of evidence presented before the court, including forensic laboratory examination results. Nevertheless, in practice, such forensic evidence is not always given sufficient weight in cases involving document forgery. This study aims to analyze the role of forensic laboratory examination results in supporting the proof of document forgery and to examine judicial considerations in evaluating and positioning such evidence within court proceedings. The findings demonstrate that forensic laboratory examination results play a crucial role in proving document forgery crimes. These results assist investigators in verifying document authenticity, identifying suspects, and providing evidentiary support through expert testimony and documentary exhibits during trial. Furthermore, judges evaluate the probative value of forensic laboratory evidence by examining the scientific methodology applied and the credibility of the forensic experts involved. When considered alongside other corroborative evidence, forensic laboratory examination results significantly aid judicial deliberation. Consistent with evidentiary standards, judges may issue verdicts based on the presence of at least two valid pieces of evidence supported by judicial conviction. The principal contribution of this study lies in clarifying the evidentiary position of forensic laboratory examination results within judicial reasoning in document forgery cases. By highlighting both the strengths and limitations of such evidence, this research contributes to legal scholarship and practice by promoting more consistent and scientifically informed judicial assessments of forensic evidence in document forgery adjudication.
