Where it is alleged that a confessional statement was obtained under duress or as a result of threat or inducement, the Courts have developed the practice of conducting a trial within trial 18 (TWT) or mini trial to ascertain the voluntariness of the statement. The onus is on the prosecution to prove that it was freely and voluntarily made … On the other hand, where the accused outrightly disowns the confession and asserts that he did not make the statement at all, it would be admitted in evidence and considered alongside other evidence led at the trial to determine its probative value.
