Crimes Act 1900

For the purposes of this Part, a document is false if, and only if, the document (or any part of the document) purports—

to have been made in the form in which it is made by a person who did not in fact make it in that form, or

to have been made in the form in which it is made on the authority of a person who did not in fact authorise its making in that form, or

to have been made in the terms in which it is made by a person who did not in fact make it in those terms, or

to have been made in the terms in which it is made on the authority of a person who did not in fact authorise its making in those terms, or

to have been altered in any respect by a person who did not in fact alter it in that respect, or

to have been altered in any respect on the authority of a person who did not in fact authorise its alteration in that respect, or

to have been made or altered on a date on which, or at a place at which, or otherwise in circumstances in which, it was not in fact made or altered, or

to have been made or altered by, or on the authority of, a person who did not in fact exist.

For the purposes of this Part, a person is to be treated as making a false document if the person alters a document so as to make it false within the meaning of this section (whether or not it is false in some other respect apart from that alteration).

For the purpose of the application of this section, a document that purports to be a true copy of another document is to be treated as if it were the original document.
