To give effect to this policy, every person who engages, whether exclusively or not, in the sale of goods by wholesale is required to register. Upon registration, he becomes bound to keep proper books, make returns of his sales, and pay the tax. He receives a certificate bearing a number and this certificate he is bound to quote when he buys goods, unless, besides being a wholesale merchant, he is a retailer and he sells principally by retail. A sale to a person who quotes his certificate is not the subject of tax, and thus, if there be successive sales to wholesalers, the goods do not incur tax until the last wholesaler sells them to the retailer. Then an ad valorem duty is imposed on that sale, which presumably was considered likely to be at a price higher than the preceding sales.
That is, I think, a sufficient description of the system to indicate that the purpose which lies behind the registration of manufacturers and wholesale merchants and the use of certificates of registration is to determine the proper incidence of sales tax in accordance with the scheme of taxation. A certificate of registration will not assist in the assessment or calculation of the sales tax which a wholesaler may be liable to pay. The existence of a certificate and the quotation of its number may determine whether a tax is or is not imposed upon a particular sale and so determine liability for sales tax, but a decision not to register or to register a wholesaler and to issue a certificate can have nothing to say about the assessment or calculation of sales tax which may be payable by that wholesaler or by any other wholesaler. The process of registration and the issue of certificates provides the apparatus which enables "decisions making, or forming part of the process of making, or leading up to the making of, assessments or calculations of" sales tax to be made, but decisions relating to the apparatus itself do not fall within that description. No doubt in one sense any decision under the Sales Tax Assessment Acts is a decision leading up to the making of an assessment or calculation of sales tax because the imposition of sales tax is the ultimate purpose of the legislation, but par. (e) of Sch. 1 of the Administrative Decisions (Judicial Review) Act makes a distinction between decisions answering that description and other decisions under the Sales Tax Assessment Acts. Given that distinction, I think that decisions relating to the registration of manufacturers or wholesalers and the issue of certificates of registration are of a sufficiently preliminary nature to fall outside the description contained in par. (e).
