The parens patriae jurisdiction
20The parens patriae jurisdiction of a Court such as this is of ancient origin. It goes back to the old Courts of Chancery. In the course of submissions Mr Zucker referred me to an expression of the jurisdiction by the then Lord Chancellor, Lord Cranworth, in Hope v Hope 4 De GM&G 328 at pp 344 and 345:
The jurisdiction of this Court, which is entrusted to the holder of the Great Seal as the representative of the Crown, with regard to the custody of infants rests upon this ground, that it is the interest of the State and of the Sovereign that children should be properly brought up and educated; and according to the principle of our law, the Sovereign, as parens patriae, is bound to look to the maintenance and education (as far as it has the means of judging) of all his subjects.
21Whilst that statement of general principle is undoubtedly helpful, as the jurisdiction has developed it has been described in subsequent authorities as having an essentially protective character. It is that characterisation which has given me some pause for thought in considering the question of whether the parens patriae jurisdiction would extend to the circumstances of the present case.
22In AMS v AIF [1999] HCA 26; (1999) 199 CLR 160 at [85]-[86] Gaudron J described the parens patriae jurisdiction in these terms (citations omitted):
It has been said that the parens patriae jurisdiction is "an unrestricted jurisdiction to do whatever is considered necessary for the welfare of a [child]" and that "[i]ts limits ... have not, and cannot, be defined." However, the jurisdiction is not in principle supervisory. Rather, it is a jurisdiction which, in general terms, is exercised when there is some risk to a child's welfare.
If there is a risk to the welfare of a child, the parens patriae jurisdiction will support a great variety of orders and orders of great width. It has been said that it will support orders related to "categories of cases ... such as custody, care and control, protection of property, health problems, religious upbringing, and protection against harmful associations" and that "[t]hat list is not exhaustive ... [for] the orders of [a] court in this particular jurisdiction have always been described as being of the widest nature'.
23In MAW v Western Sydney Area Health Service [2000] NSWSC 358; (2000) 49 NSWLR 231 at [27] and [31] O'Keefe J said (citations omitted):
Subject to the Commonwealth Constitution, the Supreme Court is a court of unlimited jurisdiction and as such has an inherent jurisdiction which is sufficiently wide to meet the requirements of the administration of justice. Such a jurisdiction includes a parens patriae jurisdictions ...
The parens patriae jurisdiction of the Court is essentially protective in nature and although broad, is to be exercised cautiously. Its existence and exercise are founded on a need to act on behalf of those who are in need of care and cannot act for themselves. In exercising its parens patriae jurisdiction the paramount consideration is the promotion of the health or welfare of the subject of the exercise of the jurisdiction. Its exercise should not be for the benefit of others. Furthermore, it has its limits.
24In MAW O'Keefe J ultimately concluded (at [41]) that the parens patriae jurisdiction did not extend to the Court giving consent to the surgical procedure proposed in the Summons before him:
For the foregoing reasons I am of the opinion that within its limits as presently defined the parens patriae jurisdiction of the Court does not extend to authorising a non-therapeutic surgical procedure of the kind contemplated by the present application. It is not a procedure that is necessary to preserve the life of the patient. It is not a procedure which will safeguard, secure or promote, or prevent the deterioration in, the physical or mental health of the patient. It is not a procedure which will promote the well-being of the patient. In these circumstances it could only be authorised by the Court under its parens patriae jurisdiction if yet another special category or case is recognised in respect of the surgical procedure in question in the present case.
25In my opinion, while the statements of principle in MAW are, with respect to his Honour, unimpeachable, it must be remembered that his Honour was considering and applying them in the extreme situation of consent being sought to a surgical procedure being performed upon an unconscious person. That is undoubtedly one proper application of the parens patriae jurisdiction. However, as the cases to which I have referred make clear, the jurisdiction is of a much wider application. Nevertheless, those cases also make it clear that the jurisdiction is not limitless.
26It seems to me that it should not be exercised, that is to say I do not think that it extends, to permitting orders to be made merely for convenience or where all interested parties consent. On the other hand, the notion of a protective jurisdiction necessarily, in my opinion, goes beyond matters of protection from immediately identifiable physical, psychological or emotional harm. Nor, in my opinion, should references to the need for there to be a risk to a child's welfare be taken as definitive of the extent of the jurisdiction.
27To focus on concepts of protection and risk in my opinion may lead to what I consider is an incorrectly narrow view of the scope of the jurisdiction. As Lord Cranworth's foundational dictum which I have quoted above makes clear, echoed by the references in MAW also quoted above to "the promotion of the health or welfare of the subject" and to "promote the well-being of the patient", the jurisdiction can be engaged to ensure the positive welfare of a person where there exists the real potential to do so, rather than just to prevent a proven immediate risk to that person's well-being.
