Trends of Using Forensic Evidence for Judge's Consideration of Court in Thailand.
The research used data from 690 cases judged in the supreme court of Thailand between 2003 and 2016 classified into two groups: general factor and factors based on the evidence for the case proceeding. The results of general factors showed that 62.90% of prosecutors and 99.13% of defendants were male. Prosecutors related to defendants as known persons in 66.94% of the cases. Crimes in the cases occurred in similar proportions during the day and night. The results of factors based on the evidence for case-proceedings indicated that prosecutors’ testimonies, the autopsy, and forensic evidence were related to the judgement (P<0.01), with the value of the odds ratio being 29.67, 5.46, and 3.70, respectively. In cases involving forensic evidence in the case proceedings, the court can punish 87.57% of the offenders. However, when factors which could determine the value of the odds ratio were analyzed using logistic regression, the judgement was affected by: testimonies, the report to the police, testimonies related to the prosecutor’s evidence, the autopsy, and forensic evidence (P<0.01). Factors on testimonies corresponding to the prosecutor’s evidence had the highest value of Exp(B) of 23.16. The research showed that the case-proceedings of the supreme court of Thailand used many kinds of evidence for judgement but that cases using forensic evidence resulted in the court decided without any question.
