52 In an attempt to resist the obvious conclusion that these matters give rise to a genuine dispute as to the existence of the debt claimed, Createc resorts to submissions which, as I have observed, are not so much directed to the existence of a dispute, but to its suggested resolution. Createc submits that because the invoices submitted to the bank required payment on delivery of the UVX printer, consistently with s 28 of the Sale of Goods Act 1985 (WA), delivery of the UVX printer on 6 November 2007 gave rise to a debt which could be the subject of a valid statutory demand, notwithstanding the assertions that the UVX printer was not fit for its purpose, nor capable of performing as represented. In response to the obvious proposition that the circumstances gave rise to an implied warranty of fitness for purpose, Createc relies upon s 11(3) of the Sale of Goods Act which provides that where a buyer has accepted goods, the breach of any condition to be fulfilled by the seller can only be treated as a breach of warranty, and not as a ground for rejecting the goods and treating the contract as repudiated. However, this submission begs the question as to whether the UVX printer was ever accepted by Design Signs. Section 34(1) of the Sale of Goods Act provides that a buyer who has not previously examined goods 'is not deemed to have accepted them unless and until he has had a reasonable opportunity of examining them for the purpose of ascertaining whether they are in conformity with the contract'. In the present case, it is obviously arguable that the installation and testing processes undertaken in November and early December 2007 were necessary to give Design Signs a reasonable opportunity of examining the UVX printer supplied, after which it rejected the supply of the UVX printer and called upon Createc to recover it.
