1, Protection of Human Rights and Dignity: This rule embodies the protection of the defendant's human rights and dignity. By excluding confessions obtained through torture, defendants can be prevented from being abused, forced or treated unfairly. This reflects the importance attached by the criminal justice system to the protection of human rights.
2. Principle of legal evidence: This rule embodies the principle of legal evidence, that is, only evidence obtained through legal means can be used in criminal proceedings. Extorting a confession by torture does not meet the legal standard of evidence, because it violates the defendant's free will and human rights, so it is excluded as evidence.
