Code of Criminal Procedure Article 156

Confession of an accused not extracted by violence, threat, inducement, fraud, exhausting interrogation, unlawful detention or other improper means and consistent with facts may be admitted as evidence.Confession of an accused, or a co-offender, shall not be used as the sole basis of conviction and other necessary evidence shall still be investigated to see if the confession is consistent with facts.If the accused states that his confession was extracted by improper means, his confession shall be investigated prior to investigating other evidences; if the said confession is presented by the public prosecutor, the court shall order the public prosecutor to indicate the method to prove that the confession is obtained under the free will of the accused.Where an accused has made no confession nor has there been any evidence, his guilt shall not be presumed merely because of his refusal to make a statement or remaining silent.Note: Articles 1 through 343 were amended lastly on February 6, 2003.
