Can a defendant cross-examine his co-defendant’s evidence?

The court then referred to Lord v. Colvin, supra, and said: “The opinion of the whole of the judges is that a defendant may cross-examine his co-defendant’s witnesses. If a defendant may cross-examine his co-defendant’s witnesses a fortiori he may cross-examine his co-defendant, if he gives evidence. If it is objected that there is no issue between a respondent and co-respondent, the answer is that in most cases there is no issue between co-defendants, but still the right to cross-examine exists.”
