On what basis should we judge whether a parent’s medical decision for their child is morally acceptable? In a recent article, Johan Bester attempts to answer this question by defending a version of the Best Interest Standard for parental decision making. The purpose of this paper is to identify a number of problems faced by Bester’s version of BIS and to suggest ways to redress these problems. Accordingly, we intend to advance the project of formulating a method for guiding parents’ (...) medical decision making for their children. We argue that Bester’s standard fails to accommodate the autonomy of the child and that his criteria for assessing the reasonableness of the parents’ argument for their decision is too weak. We conclude that properly addressing these worries renders his test otiose and that it ought to be replaced with the three commonly held principles of bioethics—the principles of autonomy, beneficence, non-maleficence—and a standard of reasonableness.
