8.1 Question 4
50 Question 4 identified by the applicant was whether the Tribunal took account of an irrelevant consideration, namely the subjective beliefs of the parties to the contract between the applicant and G & D Performance Tuning Pty Ltd, in deciding whether a binding agreement had been concluded. That question is rejected on a number of bases. It does not disclose a question of law.
51 First, it proceeds on a mischaracterisation of the Tribunal's reasons. The Tribunal did not take into account the subjective beliefs of the parties. On the contrary, the Tribunal found that it did not have sufficient evidence to make a finding as to whether the parties believed, on reasonable grounds, that a binding agreement had been concluded: Tribunal's Reasons at [231]. That finding was unsurprising. There was no written agreement. The applicant did not adduce evidence of what was said between Mr Denysenko and his sons to constitute the contract. The applicant did not call either of Mr Denysenko's sons to give evidence. The Tribunal's finding was therefore necessarily based on an assessment of Mr Denysenko's evidence, the invoice and the stocktake document.
52 Mr Denysenko's evidence was vague, uncertain, inconsistent and uncorroborated. In his witness statement (at [7], [9] and [10]), Mr Denysenko said he received an invoice in September 2009 "purportedly for the supply of automotive parts to the Applicant". He also said that the payment terms were flexible and that "there is no question whatsoever that these invoices were not due for payment as at 31 December 2009." In the absence of any evidence of the conversation or conversations constituting the alleged contract, the basis of the applicant's alleged obligation to pay was and remained uncertain. Then, in cross-examination, Mr Denysenko said that he and his sons worked out the figure that was on the invoice, payment of the invoice was dependent on "when that (sic) we got the money or whenever we kicked up a little bit…", that the stock had not been "presented" when the invoice was created and when the stock was presented it was rejected. At its highest, the applicant's case was that the goods the subject of the invoice existed at the time of the invoice because they were the subject of the stocktake document. That is insufficient.
53 There were other evidentiary issues. Both the applicant's business and G & D Performance Tuning Pty Ltd's business were conducted on the same premises. Why would the applicant dispute a liability that he had purportedly determined himself in relation to stock at the applicant's premises? The Tribunal was best placed to assess the credibility of Mr Denysenko's oral testimony.
54 The applicant's submission that so long as "the language employed by the parties is not 'so obscure and so incapable of any definite or precise meaning that the Court is unable to attribute to the parties any particular intention' the contract cannot be held to be void or uncertain or meaningless", goes nowhere because the applicant did not adduce any evidence of the language used in the conversations constituting the alleged contract: see [51] above. Rather, Mr Denysenko gave vague and inconsistent evidence of what he considered to be the applicant's obligation to pay. The applicant did not prove whether it was intended by Mr Denysenko and his sons that the applicant would have a present obligation to pay $500,500 payable at an unspecified time in the future or whether it was intended that an obligation to pay would only arise on "presentation" of the goods to the satisfaction of the applicant or when the applicant had sufficient money to pay or when both of those conditions were satisfied. The alleged contract was arguably so vague that it was not binding: Toyota Motor Corporation Australia Ltd v Ken Morgan Motors Pty Ltd [1994] 2 VR 106 at 130.
55 Even if, contrary to the Tribunal's finding, there was a binding contract between the applicant and G & D Performance Tuning Pty Ltd, the evidence did not establish a presently existing liability at the relevant time, being at the end of the quarterly tax period on 30 September 2009. A contingent liability is not sufficient to satisfy the requirements of s 11-5(c) of the GST Act, that you provide, or are liable to provide, consideration for the supply: see [9] above. The provision requires a presently existing liability - a debt: cf Federal Commissioner of Taxation v James Flood Pty Ltd (1953) 88 CLR 492 and Nilsen Development Laboratories Pty Ltd v Federal Commissioner of Taxation (1981) 144 CLR 616. A potential liability, subject to delivery of the goods or a condition of "when … we got the money or whenever we kicked up a little bit…", is not a presently existing liability.
56 Finally, the question again impermissibly invites the Court to examine and consider the weight to be accorded to evidence before the Tribunal, including the oral evidence of Mr Denysenko. That is not a question of law. That is an impermissible challenge to a finding of fact.
57 Question 4 of the notice of appeal is rejected.
