193. Marion’s case was concerned with the administration of non-therapeutic
treatment to prevent pregnancy of a child who would never have the capacity to
consent to the procedure. It came after Re Eve which concluded that as the
parens patriae jurisdiction could only be exercised for the benefit of the
incompetent person and non-therapeutic sterilization could not safely be said to
be in the person’s best interests, the procedure could not be authorised under
that jurisdiction. In Marion’s case the High Court concluded that, in the
exercise of the welfare power, the court could authorise non-therapeutic
sterilization as a special category or case.
194. A hysterectomy was proposed for Marion for the purpose of preventing
pregnancy and menstruation with its psychological and behavioural
consequences. An ovariectomy was proposed to stabilise hormonal fluxes so as
to eliminate behavioural responses and consequential stress. Marion’s parents
applied to the Family Court for an order authorising these surgeries or, in the
alternative, a declaration that they could consent to the procedures. In deciding
that the parents could not consent to the procedures without court authorisation,
the High Court distinguished between “therapeutic” and “non-therapeutic”
procedures and qualified parental power in relation to a decision to authorise a
particularly grave, non-therapeutic procedure for a child who lacked the
capacity to give informed consent.
195. At 249 – 250, Mason CJ, Dawson, Toohey and Gaudron JJ said:
There are, in our opinion, features of a sterilization procedure or, more
accurately, factors involved in a decision to authorize sterilization of
another person which indicate that, in order to ensure the best protection
of the interests of a child, such a decision should not come within the
ordinary scope of parental power to consent to medical treatment. Court
authorisation is necessary and is, in essence, a procedural safeguard. Our
reasons for arriving at this conclusion, however, do not correspond
precisely with any of the judgments considered. We shall, therefore, give
our reasons. But first it is necessary to make clear that, in speaking of
sterilization in this context, we are not referring to sterilization which is
a by-product of surgery appropriately carried out to treat some
malfunction or disease. We hesitate to use the expressions “therapeutic”
and “non-therapeutic”, because of their uncertainty. But it is necessary to
make the distinction, however unclear the dividing line may be.
As a starting point, sterilization requires invasive, irreversible and major
surgery. But so do, for example, an appendectomy and some cosmetic
surgery, both of which, in our opinion, come within the ordinary scope of a
parent to consent to. However, other factors exist which have the combined
effect of marking out the decision to authorize sterilization as a special
case. Court authorization is required, first, because of the significant risk of
making the wrong decision, either as to a child’s present or future capacity
to consent or about what are the best interests of a child who cannot
