[14] The time at which the property passed became important to the applicant's argument because, under s 14(3), the only material that may be included in the valuation of goods under s 14 is that that has become or, on payment, will become the property of the party or other person for whom the construction work is being carried out. If property does not fit that description the goods are not to be included in the valuation. There is a finding, however, that property passed on delivery. While the adjudicator does not elaborate on the reason for this, it does not seem consistent with the terms in which the reasons are couched that it was argued that, by operation of the rules in the Sale of Goods Act 1896, the goods were unascertained goods, and acceptance by the buyer became a relevant factor. In this context, it will be recalled that the letter of 28 July 2006 spoke of acceptance in reliance of certain test results provided by the second respondent. If it is to be said that that is equivocal and that there had been no acceptance, it is indicative of the factual issues that remain unresolved and why, perhaps, the adjudicator found as he did. At the least, if, as appears from the terms of the adjudication, it may have been argued that the property passed only on payment, having regard to clause 6 of the General Conditions of Supply, it may be doubted whether it has that effect.
