I am in grave difficulty to agree with the submission of learned Senior Advocate. First, the first leg of his submission implies that an affidavit admitted as an exhibit is not open to cross-examination. This conclusion is drawn from his argument that the difference between an affidavit and a deposition which is a written testimony is that the latter is open to cross-examination. That is not my understanding of the law. A party is free to cross-examine on an affidavit admitted in evidence, particularly where there is a counter-affidavit. Where there is no counter-affidavit, then the deposition will be generally deemed to be correct. In the circumstances a blanket statement such as the one by Counsel, cannot be correct.
