4 The terms, "Excise Tariff" and "Excise Tariff alteration" are defined in s 4(3) of the Excise Act:
A reference in this Act or in any other Act to an Excise Tariff or Excise Tariff alteration proposed in the Parliament shall be read as a reference to an Excise Tariff or Excise Tariff alteration proposed by a motion moved in the House of Representatives, and an Excise Tariff or Excise Tariff alteration proposed by a motion so moved shall be deemed to have been proposed in the Parliament at the time at which the motion was moved.
5 Pursuant to s 160B of the Excise Act, the Commissioner of Taxation may, in certain circumstances, publish a notice of intention to propose an Excise Tariff or an Excise Tariff alteration. Section 160B(2) provides that where such a notice has been published in accordance with the section, "the Excise Tariff or Excise Tariff alteration shall, for the purposes of this Act (other than section 114) and any other Act, be deemed to be an Excise Tariff or an Excise Tariff alteration, as the case may be, proposed in the Parliament".
6 It is s 54 that imposes the liability to pay excise duty on the "licensed manufacturer of excisable goods, or, where the owner of excisable goods enters them for home consumption, the owner". Section 58 deals with the entry of goods for home consumption. It provides in s 58(1A) that entry "shall be made in accordance with an approved form, or in a manner approved by the CEO", that is by the Commissioner. Section 59 provides that excise duty must be paid at the times specified "at the rate in force" at that time, however the obligation is expressly subject to ss 59A and 59AA.
7 Under s 59A the Commissioner has power to take steps to protect the revenue in anticipation of an increase in the duty applicable to goods of a particular kind. The regime is complex and it is not necessary here to describe it in detail. It is sufficient to note that the Commissioner "shall have the right, before the entry is passed, in addition to requiring Excise duty to be paid on the goods at the rate in force at the time of entry of the goods, to require and take, for the protection of the revenue in relation to any additional amount of duty that may become payable on the goods, or the part of the goods … security by way of cash deposit of an amount equal to the amount of duty payable on the goods, or on that part of the goods at the rate in force at the time of entry of the goods"; s 59A (8).
8 As an alternative to entry for home consumption pursuant to s 58, the Commissioner (or authorised officer) may give a person written permission to deliver the goods for home consumption "notwithstanding that an entry of the goods for home consumption has not been made and passed under this Act"; s 61C(1). This permission may be subject to such conditions as, in the opinion of the Commissioner, "are necessary for the protection of the revenue or for the purpose of ensuring compliance with the Excise Acts"; s 61C(3).
