does spousal privilege exist at common law?
5 The resolution of this first issue revolves around two relatively recent appeal court decisions to which I was referred by both counsel: Ms Martin for Ms Stoddart and Mr Cooke QC for the Crime Commission.
6 First, in Callanan v B [2005] 1 Qd R 348 ("B"), the Queensland Court of Appeal unanimously held that spousal privilege existed at common law: see McMurdo JA at [1], McPherson JA at [8] and Jerrard JA at [22]. That decision involved a refusal by a spouse to answer questions asked in the course of a crime investigation being conducted under the Crime and Misconduct Act 2001 (Qld) ('the Qld Act'). In their decisions, McPherson and Jerrard JJA relied extensively on an article by Mr D Lusty entitled "Is there a common law privilege against spousal incrimination?" (2004) 27 UNSWLJ 1.
7 Secondly, in S v Boulton (2006) 151 FCR 364 ("S"), a Full Court of this Court came to the same conclusion: see Black CJ at [16] to [28], Jacobsen J at [75] to [99] and Greenwood J at [171]. While the central issue in S was whether spousal privilege extended to a de facto spouse, the Full Court had to determine, as a necessary first step, whether spousal privilege existed at all.
8 At first instance in S ((2005) 155 A Crim R 152), Kiefel J considered she should follow the decision in B as a matter of judicial comity (at [31] and [32]), even though her Honour was of the view that the common law did not recognise the concept of spousal privilege: see at [25].
9 In his decision in S, Black CJ examined the difficulties identified by Kiefel J with the existence of spousal privilege: see at [17] to [22]. In particular, his Honour noted the comments made by Kiefel J about the confusion created by statements that had related compellability to privilege: see at [20]. Furthermore, he noted the historical difficulty with the existence of a spousal privilege when the earlier common law rules relating to spousal incompetence and non-compellability meant that it would almost never have arisen for consideration: see at [19]. Ultimately, the Chief Justice concluded that Bshould be followed: see at [25] and [28]. In reaching this conclusion, his Honour noted that:
● there were differing opinions as to whether a definitive modern spousal privilege existed;
● there was one common law in Australia;
● there was a need for certainty in its interpretation;
● the decision in B had not been contradicted;
● it involved a careful analysis of the relevant legal history; and
● it was based on a scholarly article on the subject.
10 Jacobson J, with whom Greenwood J agreed, traced the historical evolution of the notions of competence, compellability and privilege and concluded that the common law did recognise a spousal incrimination privilege: see at [99]. Jacobson J noted the uncertainty surrounding the notions of compellability and privilege raised by Kiefel J (at [93]) but respectfully disagreed with her Honour as to what flowed from the proposition that a wife was not compellable as a witness: see at [98]. Jacobson J relied particularly on the decision of Barley J in R v Inhabitants of All Saints Worcester (1817) 105 ER 1215 and concluded that spousal privilege was related to non-compellability: see [91]. It should, perhaps, be noted that Kiefel J had doubted the correctness of this decision: see the reasons of Kiefel J at [15].
11 In addition to these two appeal court decisions, it is worth mentioning that in Stoten v Sage (2005) 144 FCR 487 ("Stoten"), Dowsett J essentially took the same approach as Kiefel J in S. While his Honour doubted the existence of such a common law privilege independent of statute, for reasons of judicial comity, he decided he should follow the decision in B: see Stoten at [6] and [14].
12 Since the resolution of this issue was a necessary part of the decision in S and, therefore, part of the ratio decidendi, I consider I am bound to follow the Full Court's decision in that case. Even if I were not so bound, I would not be so bold as to ignore the principle of judicial comity in relation to the decision in B, when, as I have noted above, five judges of this Court have recently followed it. It follows that I should hold that spousal privilege or immunity does exist at common law.
