39 Third, the absence of evidence from either Mr Dean or Ms Chatila is of significance. I would have expected, in a case where the primary submission relates to the efforts to obtain the transcript and the response received from the Magistrates' Court Registry officers, that evidence would have been adduced from one or other of the two persons involved in the handling of the file. I reject the submission put on behalf of Mr Burlock that the interlocutory nature of the application does not require such evidence. To the contrary, where one is seeking to extend the time for prosecuting an appeal, particularly where the test is one requiring "exceptional circumstances" to be demonstrated, the proofs must be clear and cogent to enable a Court to be satisfied the onus has been discharged. Indeed, solicitors' affidavits are regularly filed in applications where it is sought to explain the delay in complying with limitation periods. Mr Burlock's affidavit in this proceeding was filed by the solicitors. Mr Dean and Ms Chatila were both employed by the solicitors. There is no evidence from either of them as to the steps taken to obtain the transcript or, indeed, as to the prosecution of the appeal. There is no acceptable explanation for the absence of evidence from either of them. It could not seriously be suggested that because Ms Chatila no longer works for Isaac Brott & Co, she is incapable of providing an affidavit deposing precisely what went on between her and the Registry staff. A Jones v Dunkell[21] inference can, I think, be readily drawn. I infer that neither Mr Dean nor Ms Chatila would have assisted Mr Burlock's assertion as to the efforts made to procure the digital recording. The failure to adduce evidence from them also permits me to draw inferences more confidently in favour of the case put by Wellington Street.[22]
