BIG (an association of doctors and radiologists) ordered an X-ray tube from BEC on 5 February 1997 for $122,474. The purchase price was paid in two instalments. When BEC's technician attempted to install the tube, it broke. A second tube also broke during installation. On 11 September 1998, BEC agreed to refund the purchase price but without interest. BIG demanded payment with interest by 1 December 1998. On 18 January 1999, BEC tendered payment without interest in "full and final settlement," which BIG rejected. BIG issued summons on 22 January 1999 claiming the refund with interest from 1 December 1998 at the prescribed rate, plus damages. BEC paid the capital amount on 9 July 1999. BIG withdrew the damages claim but persisted with the claim for mora interest and costs. The High Court awarded interest and costs to BIG on 27 October 2000. BEC filed a fatally defective notice of appeal on 16 November 2000 (omitting the Registrar's address and the judgment date). BEC then applied for an extension of time to appeal.
