Introduction

The study of law and the judgment in the criminal case, especially with respect to the DNA evidence in the United States, the United Kingdom and Australia also other countries, the study guides in terms of the pros and cons of the DNA evidence in proving the criminal justice system. Consequently, the using the DNA evidence will benefit greatly with the Thai and Portuguese Criminal Justice.

In the process before trial, the step of seeking, collecting DNA evidence and the act listening to the statements and weighting the DNA evidence has to be carried before a Thai court can make any considerations. This is true not only in the terms of laws but also in the usage of discretion when deciding which evidence should be employed. The current trend in Thailand, scientific evidence which surrounds an incident is the most important in terms of weight and credibility of DNA evidence.

However, several murder cases have different issues, the issue of the facts and issue of the law which needs to be set up to the standard. Now the judge 's discretion has difficulty summarizing the rules. Therefore, it is necessary to find a way for the corrective practice.

In Thailand, the DNA technology has shown a major role in important events in the country. On25 December 2004, the tsunami occurred in Phuket and Phang Nga province, where is a favourite tourist attraction in Thailand.This tragedy led to loss of many people and foreign tourists who came to relax during Christmas holidays. At that time, DNA evidence led to the identification of missing people and dead people but at that time there was no DNA collecting record like DNA Database in
