amendments to the provisions regarding forensic science under the Code of Criminal Procedure. 100. The forensics and expert testimony system should keep updating its kinds of methods for assessing evidence in order to keep up with technological developments. This is to respond to the needs of investigation and trial, help to establish levels of scientific authority and diversified forensic science systems, and enhance the impartiality of expert testimony organizations. This impartiality can be facilitated if expert testimony and evidence assessment organizations are compiled into a list that courts can select from to find expert witnesses or relevant organizations.
