The Appellant, a street boy, was charged with and convicted of unnatural offence. He was sentenced to 30 years’ imprisonment. Being dissatisfied with the decision, he appealed to the High Court, which dismissed his appeal. He further appealed to the Court of Appeal of Tanzania contending that the trial court misdirected itself in taking the evidence of PW2 without conducting a voire dire examination and acting on it without requisite corroboration and that the Police had also failed to do the same when taking the statement of the same boy (PW2). He also complained that the PF3 and sketch plan were wrongly admitted in evidence without calling its makers to testify, and that the right of defence was not properly explained to him.
