5 The applicant submits that the delegate has confused the criterion in clause 457.223(7)(a)(i) with the criteria in par (b)(ii) and (iii). The respondent claims that it is not inappropriate for a delegate to take into account the matters set out in par (b) when considering whether an applicant is a principal, and relies on Guo v Minister for Immigration and Multicultural Affairs [2000] FCA 146 at par 16 where O'Loughlin J said that the role of the applicant in the business is a relevant consideration in determining whether he or she is a principal. However the delegate did more than take the par (b)(ii) and (iii) matters into account. He treated non‑satisfaction of them as determinative of non‑satisfaction of par (a)(i). Clause 457.223(7)(a) and (b) contain cumulative requirements. It cannot be said that because par (b)(ii) and (iii) are not satisfied, par (a)(i) is not. Situations can be envisaged in which a person may be a principal of a business within par (a) yet fail to fulfil the requirements of par (b)(ii) and/or (iii). For example, a partner who has put in a great deal of capital and has a right to veto certain decisions made by the other partners, but otherwise plays no part in the business, is probably a principal by virtue of his financial power and his potential impact on the company, notwithstanding that he does not maintain a direct and continuous involvement in the business, and does not make decisions affecting the overall direction and performance of the business from day to day. The delegate's statement "I am therefore not satisfied that you propose to develop in Australia a business activity that will be conducted by you as principal" refers back to the statement that the delegate is not satisfied of the matters in par (b)(ii) and (iii). In the earlier passage the delegate quotes verbatim from par (b)(ii) and substantially verbatim from par (b)(iii), though in relation to the latter he adds the words "or be in a position of control that allows you", which is derived from the Procedures Advice Manual ("PAM"). Accordingly, the delegate's conclusion that failure to satisfy par (b)(ii) and (iii) involves a failure to satisfy par (a)(i) is an error of law.
6 The applicant's submission that the delegate imposed a test requiring a higher level of authority and control from a principal than is required by the regulations was developed by reference to the decision of Heerey J in Huang v Minister for Immigration and Multicultural Affairs (2000) 105 FCR 34 at [11] that "principal" in par (a)(i)
