This article addresses how bodily integrity has been mobilised in the context of genital cutting of male infants and the extent to which the concept is taken into account in legal decision-making in the United Kingdom. While bioethicists have debated whether interventions on children's bodies are more appropriately determined on the basis of hypothetical consent or in the child's best interest, it is clear that in law the relevant test is whether interventions are in the child's best interest. As the (...) issue of nonconsensual genital cutting of infants has become more contested, courts have been asked to adjudicate on the best interests of infants in situations where their caregivers disagree about procedures. Although this body of jurisprudence remains (surprisingly) small, in this article we argue that, while there are now discernible trends in such cases (e.g. deferring decision-making until the child has the requisite capacity to decide, engaging with certain human rights norms), too often judicial reasoning about a child's best interests remains largely empty of reasoned content, and in certain respects is regressing. Using the recent case of Re P to exemplify this logic, and drawing on our previous work advocating the value of embodied integrity, we argue that judges should adopt a more substantive framework of values in judging the child's corporeal and other interests in such cases. This would move best interests assessments beyond a mere formalistic exercise and lead to better reasoned legal judgements. (shrink)
