Legislative history

The Parliament of South Australia enacts as follows:
Part 1—Preliminary
1—Short title
This Act may be cited as the Electronic Transactions Act 2000.
3—Object
The object of this Act is to provide a regulatory framework that—
	(a)	recognises the importance of the information economy to the future economic and social prosperity of Australia; and
	(b)	facilitates the use of electronic transactions; and
	(c)	promotes business and community confidence in the use of electronic transactions; and
	(d)	enables business and the community to use electronic communications in their dealings with government.
4—Simplified outline
	(1)	The following is a simplified outline of this Act:
	(a)	for the purposes of a law of this jurisdiction, a transaction is not invalid because it took place by means of one or more electronic communications; and
	(b)	the following requirements imposed under a law of this jurisdiction can generally be met in electronic form:
	(i)	a requirement to give information in writing;
	(ii)	a requirement to provide a signature;
	(iii)	a requirement to produce a document;
	(iv)	a requirement to record information;
	(v)	a requirement to retain a document; and
	(c)	for the purposes of a law of this jurisdiction, provision is made for determining the time and place of the dispatch and receipt of an electronic communication; and
	(d)	the purported originator of an electronic communication is bound by it for the purposes of a law of this jurisdiction only if the communication was sent by the purported originator or with the authority of the purported originator.
	(2)	Part 2A contains provisions applying to contracts involving electronic communications, including provisions (relating to the internet in particular) for the following:
	(a)	an unaddressed proposal to form a contract is to be regarded as an invitation to make offers, rather than as an offer that if accepted would result in a contract;
	(b)	a contract formed automatically is not invalid, void or unenforceable because there was no human review or intervention;
	(c)	a portion of an electronic communication containing an input error can be withdrawn in certain circumstances;
	(d)	the application of certain provisions of Part 2 to the extent they do not apply of their own force.
5—Interpretation

	(b)	the method used was either—
	(i)	as reliable as appropriate for the purpose for which the electronic communication was generated or communicated, in the light of all the circumstances, including any relevant agreement; or
	(ii)	proven in fact to have fulfilled the functions described in paragraph (a), by itself or together with further evidence; and
	(c)	the person to whom the signature is required to be given consents to that requirement being met by way of the use of the method mentioned in paragraph (a).

10—Production of document
	(1)	If, under a law of this jurisdiction, a person is required to produce a document that is in the form of paper, an article or other material, that requirement is taken to have been met if the person produces, by means of an electronic communication, an electronic form of the document, where—
	(a)	having regard to all the relevant circumstances at the time the communication was sent, the method of generating the electronic form of the document provided a reliable means of assuring the maintenance of the integrity of the information contained in the document; and

	(2)	If, under a law of this jurisdiction, a person is permitted to produce a document that is in the form of paper, an article or other material, then, instead of producing the document in that form, the person may produce, by means of an electronic communication, an electronic form of the document, where—
	(a)	having regard to all the relevant circumstances at the time the communication was sent, the method of generating the electronic form of the document provided a reliable means of assuring the maintenance of the integrity of the information contained in the document; and
	(b)	at the time the communication was sent, it was reasonable to expect that the information contained in the electronic form of the document would be readily accessible so as to be useable for subsequent reference; and

	(3)	For the purposes of this section, the integrity of information contained in a document is maintained if, and only if, the information has remained complete and unaltered, apart from—
	(a)	the addition of any endorsement; or
	(b)	any immaterial change,
which arises in the normal course of communication, storage or display.
	(4)	This section does not affect the operation of any other law of this jurisdiction that makes provision for or in relation to requiring or permitting electronic forms of documents to be produced, in accordance with particular information technology requirements—
	(a)	on a particular kind of data storage device; or
	(b)	by means of a particular kind of electronic communication.
11—Retention of information and documents
	(1)	If, under a law of this jurisdiction, a person is required to record information in writing, that requirement is taken to have been met if the person records the information in electronic form, where—
	(a)	at the time of the recording of the information, it was reasonable to expect that the information would be readily accessible so as to be useable for subsequent reference; and
	(b)	if the regulations require that the information be recorded on a particular kind of data storage device—that requirement has been met.
	(2)	If, under a law of this jurisdiction, a person is required to retain, for a particular period, a document that is in the form of paper, an article or other material, that requirement is taken to have been met if the person retains, or causes another person to retain, an electronic form of the document throughout that period, where—
	(a)	having regard to all the relevant circumstances at the time of the generation of the electronic form of the document, the method of generating the electronic form of the document provided a reliable means of assuring the maintenance of the integrity of the information contained in the document; and
	(b)	at the time of the generation of the electronic form of the document, it was reasonable to expect that the information contained in the electronic form of the document would be readily accessible so as to be useable for subsequent reference; and

	(4)	If, under a law of this jurisdiction, a person (the first person) is required to retain, for a particular period, information that was the subject of an electronic communication, that requirement is taken to have been met if the first person retains, or causes another person to retain, in electronic form, the information throughout that period, where—
	(a)	at the time of commencement of the retention of the information, it was reasonable to expect that the information would be readily accessible so as to be useable for subsequent reference; and
	(b)	having regard to all the relevant circumstances at the time of commencement of the retention of the information, the method of retaining the information in electronic form provided a reliable means of assuring the maintenance of the integrity of the information contained in the electronic communication; and
	(c)	throughout that period, the first person also retains, or causes the other person to retain, in electronic form, such additional information obtained by the first person as is sufficient to enable the identification of the following:

	(ii)	the destination of the electronic communication;
	(iii)	the time when the electronic communication was sent;
	(iv)	the time when the electronic communication was received; and

	(5)	For the purposes of subsection (4), the integrity of information that was the subject of an electronic communication is maintained if, and only if, the information has remained complete and unaltered, apart from—
	(a)	the addition of any endorsement; or

which arises in the normal course of communication, storage or display.

Division 3—Other provisions relating to laws of this jurisdiction
13—Time of dispatch
	(1)	For the purposes of a law of this jurisdiction, unless otherwise agreed between the originator and the addressee of an electronic communication, the time of dispatch of the electronic communication is—
	(a)	the time when the electronic communication leaves an information system under the control of the originator or of the party who sent it on behalf of the originator; or
	(b)	if the electronic communication has not left an information system under the control of the originator or of the party who sent it on behalf of the originator—the time when the electronic communication is received by the addressee.
Note—
Paragraph (b) would apply to a case where the parties exchange electronic communications through the same information system.
	(2)	Subsection (1) applies even though the place where the information system supporting an electronic address is located may be different from the place where the electronic communication is taken to have been dispatched under section 13B.
13A—Time of receipt
	(1)	For the purposes of a law of this jurisdiction, unless otherwise agreed between the originator and the addressee of an electronic communication—
	(a)	the time of receipt of the electronic communication is the time when the electronic communication becomes capable of being retrieved by the addressee at an electronic address designated by the addressee; or
	(b)	the time of receipt of the electronic communication at another electronic address of the addressee is the time when both—
	(i)	the electronic communication has become capable of being retrieved by the addressee at that address; and
	(ii)	the addressee has become aware that the electronic communication has been sent to that address.
	(2)	For the purposes of subsection (1), unless otherwise agreed between the originator and the addressee of the electronic communication, it is to be assumed that the electronic communication is capable of being retrieved by the addressee when it reaches the addressee's electronic address.
	(3)	Subsection (1) applies even though the place where the information system supporting an electronic address is located may be different from the place where the electronic communication is taken to have been received under section 13B.
13B—Place of dispatch and place of receipt
	(1)	For the purposes of a law of this jurisdiction, unless otherwise agreed between the originator and the addressee of an electronic communication—
	(a)	the electronic communication is taken to have been dispatched at the place where the originator has its place of business; and
	(b)	the electronic communication is taken to have been received at the place where the addressee has its place of business.
	(2)	For the purposes of the application of subsection (1) to an electronic communication—
	(a)	a party's place of business is assumed to be the location indicated by that party, unless another party demonstrates that the party making the indication does not have a place of business at that location; and
	(b)	if a party has not indicated a place of business and has only 1 place of business, it is to be assumed that that place is the party's place of business; and
	(c)	if a party has not indicated a place of business and has more than 1 place of business, the place of business is that which has the closest relationship to the underlying transaction, having regard to the circumstances known to or contemplated by the parties at any time before or at the conclusion of the transaction; and
	(d)	if a party has not indicated a place of business and has more than 1 place of business, but paragraph (c) does not apply—it is to be assumed that the party's principal place of business is the party's only place of business; and
	(e)	if a party is a natural person and does not have a place of business—it is to be assumed that the party's place of business is the place of the party's habitual residence.
	(3)	A location is not a place of business merely because that is—
	(a)	where equipment and technology supporting an information system used by a party are located; or
	(b)	where the information system may be accessed by other parties.
	(4)	The sole fact that a party makes use of a domain name or electronic mail address connected to a specific country does not create a presumption that its place of business is located in that country.
14—Attribution of electronic communications
	(1)	For the purposes of a law of this jurisdiction, unless otherwise agreed between the purported originator and the addressee of an electronic communication, the purported originator of the electronic communication is bound by that communication only if the communication was sent by the purported originator or with the authority of the purported originator.
	(2)	Subsection (1) does not affect the operation of a law of this jurisdiction that makes provision for—
	(a)	conduct engaged in by a person within the scope of the person's actual or apparent authority to be attributed to another person; or
	(b)	a person to be bound by conduct engaged in by another person within the scope of the other person's actual or apparent authority.

Part 2A—Additional provisions applying to contracts involving electronic communications
14A—Application and operation of Part
This Part applies to the use of electronic communications in connection with the formation or performance of a contract between parties where the proper law of the contract is (or would on its formation be) the law of this jurisdiction, and so applies—
	(a)	whether some or all of the parties are located within Australia or elsewhere; and
	(b)	whether the contract is for business purposes, for personal, family or household purposes, or for other purposes.
14B—Invitation to treat regarding contracts
	(1)	A proposal to form a contract made through 1 or more electronic communications that—
	(a)	is not addressed to 1 or more specific parties; and
	(b)	is generally accessible to parties making use of information systems,
is to be considered as an invitation to make offers, unless it clearly indicates the intention of the party making the proposal to be bound in case of acceptance.
	(2)	Subsection (1) extends to proposals that make use of interactive applications for the placement of orders through information systems.
14C—Use of automated message systems for contract formation—non‑intervention of natural person
A contract formed by—
	(a)	the interaction of an automated message system and a natural person; or
	(b)	the interaction of automated message systems,
is not invalid, void or unenforceable on the sole ground that no natural person reviewed or intervened in each of the individual actions carried out by the automated message systems or the resulting contract.
14D—Error in electronic communications regarding contracts
	(1)	This section applies in relation to a statement, declaration, demand, notice or request, including an offer and the acceptance of an offer, that the parties are required to make or choose to make in connection with the formation or performance of a contract.
	(2)	If—
	(a)	a natural person makes an input error in an electronic communication exchanged with the automated message system of another party; and
	(b)	the automated message system does not provide the person with an opportunity to correct the error,
the person, or the party on whose behalf the person was acting, has the right to withdraw the portion of the electronic communication in which the input error was made if—
	(c)	the person, or the party on whose behalf the person was acting, notifies the other party of the error as soon as possible after having learned of the error and indicates that he or she made an error in the electronic communication; and
	(d)	the person, or the party on whose behalf the person was acting, has not used or received any material benefit or value from the goods or services, if any, received from the other party.
	(3)	The right of withdrawal of a portion of an electronic communication under this section is not of itself a right to rescind or otherwise terminate a contract.
	(4)	The consequences (if any) of the exercise of the right of withdrawal of a portion of an electronic communication under this section are to be determined in accordance with any applicable rule of law.
Note—
In some circumstances the withdrawal of a portion of an electronic communication may invalidate the entire communication or render it ineffective for the purposes of contract formation (see paragraph 241 of the UNCITRAL explanatory note for the United Nations Convention on the Use of Electronic Communications in International Contracts).
14E—Application of Act in relation to contracts
	(1)	Subject to subsection (2), the provisions of sections 7, 13, 13A and 13B apply to—
	(a)	a transaction constituted by or relating to a contract; or
	(b)	an electronic communication relating to the formation or performance of a contract,
in the same way as they apply to a transaction or electronic communication referred to in that Part, and so apply as if the words "For the purposes of a law of this jurisdiction" and "under a law of this jurisdiction" were omitted.
	(2)	However, this Part (including subsection (1)) does not apply to or in relation to a contract to the extent that—
	(a)	Part 2 would of its own force have the same effect as this Part if this Part applied; or
	(b)	a law of another State or Territory (that is in substantially the same terms as Part 2) would of its own force have the same effect as this Part if this Part applied.
Note—
This section applies provisions of Part 2 to contracts or proposed contracts to the extent (if any) that those provisions do not apply merely because they are expressed to apply in relation to "a law of this jurisdiction". This section also disapplies the provisions of Part 2A to the extent that Part 2 would apply of its own force. An example where Part 2 may not apply of its own force is where a contract is being negotiated in a State or Territory from a supplier located overseas.

Part 3—Miscellaneous
15—Regulations
The Governor may make such regulations as are contemplated by this Act, or as are necessary or expedient for the purposes of this Act.
