The plaintiff, whose business consists of buying eggs in New South Wales and bringing them into Victoria for sale there by retail, attacks the validity of certain provisions of the Marketing of Primary Products (Egg Marketing) Act 1965 Vict.. In the alternative he seeks a declaration that these provisions have no application to eggs which are purchased in New South Wales and brought to Victoria to be sold there by retail. The Act of 1965 to which the attack is directed amends the Marketing of Primary Products Act 1958 Vict. which is referred to in the amending Act as the Principal Act, and before dealing with the plaintiff's contentions it is desirable to give an outline of the relevant provisions of both Acts. Division 1 of Pt I of the Principal Act provides for the setting up of marketing boards for various products which may be declared by the Governor in Council to be "commodities" and contains a number of provisions dealing with marketing boards generally. Where a product has been declared to be a "commodity" and a marketing board for that commodity has been appointed, the Governor in Council may, by proclamation, declare that the property in the commodity concerned then in existence or thereafter to come into existence shall be divested from those who produced it and vest in the board as the owner thereof and the interest of the person from whom the property has been divested is thereupon converted into a claim for payment in accordance with the Act (s. 17 (1) and (2)). By sub-s. (3), nothing in that section and no proclamation made under it is to affect "such portion of any commodity as is the subject of trade commerce or intercourse between the States or as is required by the producers thereof for the purposes of such trade commerce or intercourse or as is intended by the producers thereof to be used for such trade commerce or intercourse". The Division also confers on marketing boards wide marketing powers, permits them to make levies on producers and provides for the payment by them to producers for the commodity the property in which has become vested in the board set up to deal with that commodity. Division 2 of Pt I, which comprises ss. 36 to 48 of the Act, provides for the constitution of an Egg and Egg Pulp Marketing Board and, by s. 48, that Board may make progress and final payments to producers and may deduct from such payments expenditure incurred or estimated to be incurred by the Board in the marketing and treatment of eggs and egg pulp and the costs, charges and expenses or estimated costs, charges and expenses of its administration. The amending Act of 1965 adds a number of new sections to Div. 2 of Pt I of the Principal Act. They include ss. 36A, 38A, 41A, 41B, 41C, 41D and 41E. The new s. 38A imposes upon the Board the duty to take such steps as are necessary or expedient to ensure that eggs and egg products supplied to consumers in Victoria are of satisfactory grade, quality and standard and s. 41A enables regulations to be made for these purposes. By s. 41B, all eggs and egg products sold by retail in Victoria must be sold according to such grades, qualities and standards as are prescribed and failure to comply with this requirement is made an offence. Section 41C (1) provides that "any person who owns or is entitled to sell or dispose of any eggs may present the same to the Board or a person authorized in that behalf by the Board for grading and testing and for marking or stamping so as to indicate the grade and quality". The Board is to cause all eggs so presented to be graded, tested, marked or stamped and re-delivered to the person presenting them (s. 41C (3)). It may, however, permit producers selected by it to carry out the work of grading, testing, marking or stamping eggs of which they are the producers (s. 41C (4)). By s. 41C (5), every person presenting eggs to the Board under s. 41C (1) is required to pay to the Board for its work in grading, testing, marking or stamping such eggs a fee fixed by the Board to defray the expenses incurred therefor. The Board is, from time to time, to estimate the expenditure incurred by it in carrying out the work of grading, testing, marking or stamping, and to "determine and fix accordingly" the fee to be charged (s. 41C (6)). It is made an offence for any person to sell by retail any eggs which have not been graded and tested for quality and standard and marked or stamped in accordance with the Act and regulations (s. 41D). Section 41E provides (inter alia) that s. 17 of the Principal Act, the provision which divests the producer of his property in eggs produced by him and vests it in the Board, shall not apply to owners of less than forty fowls, with the result that such persons retain their property in eggs produced by them and are at liberty to sell them, subject of course to the other provisions of the Act. By s. 36A, the words "eggs" and "egg pulp" where they occur in ss. 38A, 41A, 41B and 41C, and in certain provisions of the Principal Act to which it is unnecessary for present purposes to refer, are declared to mean "eggs and egg pulp whether or not the same (a) have been produced in Victoria; or (b) are or have at any time been vested in the Board or required to be delivered to the Board". It thus appears that eggs produced in another State and imported into Victoria the property in which has not vested in the Board under the Principal Act cannot, if the amending Act be given its prima facie meaning, be sold by retail in Victoria unless they have been graded and tested for quality and standard and marked or stamped in accordance with the Act and regulations, and that the owner of such eggs - if he wishes to sell them by retail - must present them to the Board or to some person authorized by the Board for grading, testing, marking or stamping and in the case of eggs presented to the Board must pay the fee fixed by it to make good its expenditure or estimated expenditure for performing that work. It is to these last provisions that the plaintiff's attack is directed. He contends that to be forbidden to sell by retail in Victoria eggs which he has imported from New South Wales unless he first has them graded and tested for quality and standard and stamped or marked denies him the protection of s. 92 of the Constitution. Accordingly, so he argues, the provisions which forbid him to sell by retail unless this statutory requirement is fulfilled are either wholly invalid or, if capable of being read down under s. 3 of the Acts Interpretation Act of Victoria, must be construed as having no application to him. He contends also that the fee which the Act requires him to pay to the Board to recompense it for the cost of doing the work of grading, testing and stamping or marking is a duty of excise and as such is not within the competence of the Victorian Legislature. In my opinion both contentions fail. The second of them is answered by the fact that under the Act the fee payable to the Board is payable for services rendered by it and its amount is determined by the cost to the Board or the cost, as estimated by the Board, of rendering those services.
