(1) Evidence of a Commonwealth document may be adduced by producing a document that purports to be, or to be a copy of or extract from, the Commonwealth document that is certified to be the Commonwealth document, or to be a true copy or extract, as the case may be, by:
(a) a Minister; or
(b) a person who might reasonably be supposed to have custody of the Commonwealth document.
(2) If such a document is produced, it is presumed, unless evidence that is sufficient to raise doubt about the presumption is adduced, that:
(a) the document is the Commonwealth document, or the copy of or extract from the Commonwealth document, that it purports to be; and
(b) the Minister or person certified the document as being the Commonwealth document or a true copy or extract, as the case requires.
Note: Section 5 extends the application of this section to proceedings in all Australian courts.
