Section 126B of the Act is in these terms:
"(1) The court may direct that evidence not be adduced in a proceeding if the court finds that adducing it would disclose:
(a) a protected confidence, or
(b) the contents of a document recording a protected confidence, or
(c) protected identity information.
(2) The court may give such a direction:
(a) on its own initiative, or
(b) on the application of the protected confider or confidant concerned (whether or not either is a party).
(3) The court must give such a direction if it is satisfied that:
(a) it is likely that harm would or might be caused (whether directly or indirectly) to a protected confider if the evidence is adduced, and
(b) the nature and extent of the harm outweighs the desirability of the evidence being given.
(4) Without limiting the matters that the court may take into account for the purposes of this section, it is to take into account the following matters:
(a) the probative value of the evidence in the proceeding,
(b) the importance of the evidence in the proceeding,
(c) the nature and gravity of the relevant offence, cause of action or defence and nature of the subject matter of the proceeding,
(d) the availability of any other evidence concerning the matters to which the protected confidence or protected identity information relates,
(e) the likely effect of adducing evidence of the protected confidence or protected identity information, including the likelihood of harm, and the nature and extent of harm that would be caused to the protected confider,
(f) the means (including any ancillary orders that may be made under section 126E) available to the court to limit the harm or extent of the harm that is likely to be caused if evidence of the protected confidence or the protected identity information is disclosed,
(g) if the proceeding is a criminal proceeding - whether the parties seeking to adduce evidence of the protected confidence or protected identity information is a defendant or the prosecutor,
(h) whether the substance of the protected confidence or the protected identify information has already been disclosed by the protected confider or any other person.
(5) The court must state its reasons for giving or refusing to give a direction under this section."
11 The Act applies to the adducing of evidence in a proceeding, it does not apply to the production of documents on subpoena or to a request to inspect the same; Esso Australia Resources Limited v Commissioner of Taxation of the Commonwealth of Australia [1999] HCA 67; 201 CLR 49 per Gleeson CJ, Gaudron and Gummow JJ at [16] and [17].
12 Part 36 r 13 of the SCR provides, relevantly, as follows:
"13(1) This rule applies where:
(a) the Court by subpoena or otherwise, orders any person to produce any document to;
(b) a party is required by a notice served under rule 16(1) to produce any document to; or
(c) a question is put to a person in the course of examination before,
the Court or a Judge or any officer of the Court, or any examiner, referee, arbitrator or other person authorised to receive evidence and neither Part 3.10 of the Evidence Act nor Part 3.10 of the Evidence Act 1995 of the Commonwealth is applicable.
(2) The Court shall not compel, and rule 16 shall not require, production of a document or an answer to a question, unless and until the Court directs that the production or answer shall not be prevented by this subrule:
(a) over the objection of a person if evidence of the document, or of an answer to the question, could not be adduced in the proceedings over the objection of the person, by virtue of the operation of Part 3.10 Division 1 of the Evidence Act ;
(b) if the contents or production of the document, or an answer to the question, would disclose:
(i) a protected confidence or the contents of a document recording a protected confidence or protected identity information, within the meaning of section 126B of the Evidence Act , where:
(A) consent by the protected confider within the meaning of section 126C of the Evidence Act has not been given to disclosure of the confidence, contents or information; and
(B) section 126D of the Evidence Act would not operate to stop Part 3.10 Division 1A of the Evidence Act from preventing the adducing of evidence in respect of the confidence, contents or information;
…
(3) Where a party to any proceedings claims privilege from production of any document, the Court may, if it thinks fit:
(a) permit evidence in relation to the claim to be given by any other party by affidavit or otherwise; and
(b) permit cross-examination on any affidavit used in support of the claim."
