What it does
Excise By-Law No. 75 is a narrowly framed statutory instrument made under section 165 of the Excise Act 1901, whose sole operative provision is to set the application of a particular subitem in the excise schedule. Paragraph 1 records the name of the by-law: "This by-law is the Excise By-Law No. 75." Paragraph 2 states the operative rule: "Subitem 20.1 applies to stabilised crude petroleum oil for use in the recovery or production or recovery and production of goods falling within item 20 and item 21."
Mechanically, the by-law does one thing and one thing only in the text supplied: it characterises the scope of subitem 20.1 by reference to a class of commodity described as "stabilised crude petroleum oil" and by reference to the intended use of that commodity, namely the recovery or production, or combined recovery and production, of goods captured by item 20 and item 21. The document carries the formal markers of a compilation: it was prepared by the Goods and Services Tax and Excise Centre of Expertise, Australian Taxation Office, Adelaide, with a compilation date of 18 March 2009 and an indication that the compilation took into account amendments up to and including Excise By-Law (Amendment) 2009 (No. 2). The front matter also reproduces the Table of Instruments and the Table of Amendments that record the legislative history and amendment actions affecting the by-law.
The by-law does not, in the text supplied, define "stabilised crude petroleum oil", nor does it reproduce items 20 or 21. It therefore operates by linking an external schedule entry, Subitem 20.1, to a product description and a specified use. The by-law does not itself set rates, thresholds, exemption mechanics, recordkeeping duties, penalties, or processes for remission. It is an incidental classificatory instrument: an instruction to treat a particular material, when used in particular ways, as within the scope of a pre-existing subitem in the excise schedule.
