 Smith argues that questions put to a witness under cross-examination which goes solely to his credit and, he denies it, the general rule is that his answer is final and evidence is not admissible to rebut his denial.Based on this reasoning, the court held in Murray that the accused was not indictable for false statement made when he was permitted to testify in rebuttal of a witness's denial under cross-examination.In Gibbons the court took a contrary view.
