7 I shall deal with the latter first. The document sued on is a document entitled "Bill of Exchange", purporting to be a bill of exchange under the Bills of Exchange Act 1909 (Cth) dated 7 February 2005, to which the first party is said to be the Commonwealth, the second party entities called the Solarmesh Entities, and the third party one Kenneth Clyde Ivory. The plaintiff is not a party to the "bill". Neither is there any indication that he is an endorsee of the "bill". The only signatures which appear on the bill are those of Kenneth Clyde Ivory (apparently as issuer), and a notary public of the Australian Capital Territory, one Anthony Clapham who, as the document is drawn, signed as witness to attest execution of the "bill" by Mr Ivory. The "bill" has not been signed by or on behalf of the Commonwealth; nor for that matter by or on behalf of Solarmesh Entities, nor by or on behalf of Telstra. Although there is evidence that the bill and attachments were presented to Senator Coonan, a Minister of the Commonwealth, and referred by her, there is no evidence whatsoever that she (or anyone else on behalf of the Commonwealth) has signed the bill.
8 The only basis upon which the Commonwealth is said to be liable, according to the statement of claim, is on the "bill". The Bills of Exchange Act provides, by s 28, that subject to the section, a person is not liable as drawer, endorser or acceptor of a bill if he has not signed as such. There is nothing else in the section, to which subs (1) is made subject, that is relevant for present purposes.
