In other words, the retracted confession must pass the six credibility tests forming part of our criminal jurisprudence which have been established in a long fine of cases referred to above. These are: i. Is there anything outside the confession to show that it is true? ii. Is it corroborated? iii. Are the relevant statements made in it of facts true as far as they can be tested? iv. Was the accused one who had the opportunity of committing murder? v. Is his confession possible? vi. Is it consistent with other facts which have been ascertained and have been proved?
