CAN THE ACCUSED MOVE FOR A NEW TRIAL IF HE HAS FOUND EVIDENCE THAT WOULD IMPEACH THE TESTIMONY GIVEN BY THE PROSECUTION WITNESS?
No, evidence which merely seeks to impeach the evidence upon which the conviction was based will not constitute grounds for new trial, unless it is shown that there is no other evidence sustaining the judgment of conviction except the testimony of the retracting witness.
It has to be material evidence
WHEN IS EVIDENCE CONSIDERED TO BE MATERIAL?
It is material if there is reasonable likelihood that the testimony or evidence could have been produced a different result and the accused would have been acquitted
