Where an accused person alleges that confessions or indications were obtained through assault, threats, torture, denial of access to legal representation, and other violations of constitutional rights, the State bears the onus of proving beyond reasonable doubt that the statements were made freely and voluntarily without undue influence. The test is whether there was anything to suggest that the confessor's will was swayed by external impulses improperly brought to bear, negating freedom of volition. The cumulative effect of multiple violations (assaults, prolonged detention, denial of food/water, threats to family, denial of lawyer access, detention at remote locations) must be considered together rather than isolating each incident. Where the State fails to call key witnesses (alleged assailants, medical examiners), fails to produce contemporaneous notes of interrogations, presents fabricated or contradictory police records, and fails to confirm statements despite early complaints of ill-treatment, and where police witnesses are found to be mendacious and evasive, the court may prefer the accused's testimony and find that confessions were obtained through undue influence. Such evidence must be excluded to protect the integrity of the judicial system.
