6 Secondly, the defendant pointed to the considerable delay between the failure to comply with the springing order and the application for the extension of time. It is axiomatic that if an extension of time is sought it should be sought promptly. In this case the application was not made until just over two months after judgment was entered. Mr Stokes attempts to explain the delay in his affidavit (par 7, par 8 and par 9). In summary, he says that his firm had difficulty obtaining instructions from the first plaintiff. It seems that the first plaintiff was undecided as to whether or not it wished to be a party to the proceedings. However, by letter of 17 September 1999 European Patented Attorneys acting for the second plaintiff confirmed that the first plaintiff wished to remain a party to the action and instructions were provided to make this application. Two things emerge from the explanation proffered by Mr Stokes. First, whatever may have been the difficulties with respect to the first plaintiff, there is no explanation as to why an application was not made on behalf of the second and third plaintiffs immediately after judgment was entered. Secondly, it is not clear why, when instructions were received from the first plaintiff on 17 September 1999, this application was not initiated until 8 October 1999. Once again, the explanation for the delay is not entirely satisfactory.
