This article studies the scope and substance of the alleged offenderûs and accusedûs rights to examine prosecution witnesses who have testified against him, according to Article 6 paragraph 3 (d) of the European Convention on Human Rights through the European Court of Human Rights lens. This study compares with the Thai criminal procedure law. The study has found that some sections of the Thai Criminal Procedure Code also have some deficiencies in protecting the right of the alleged offender to examine the prosecutorûs witnesses compared with the protective regime of the alleged offenderûs and accusedûs rights under the European Convention on Human Rights. Therefore, this article will recommend amendments to the Thai Criminal Procedure Code for the alleged offenderûs rights.
