In any case, I hold that failure to provide an interpreter where an accused person is represented by counsel, and there is/was no objection raised at the trial court, this will not result in vitiating the trial or result in disturbing or interfering with the judgment of a trial court. It will or may be a different thing where there is no counsel representing the accused person and where such failure will or has led to a miscarriage of justice or that the accused person has been prejudiced thereby as a result.
