By considering the death of the disability activist Engracia Figueroa as the consequence of her wheelchair being damaged by an airline, this article asks whether law could accommodate a definition of legal personhood that encompasses the possibility of bodies augmented by prosthetics, technology, and mobility aids. The use of mobility aids by disabled people and the role of prosthetic penises in so-called ‘gender fraud’ cases offer two useful provocations to consider the ways in which legal personhood, if defined as largely mapping on to an ideal, normative body, is becoming an increasingly inadequate legal concept in the modern age. Drawing on the work of Donna Haraway and the figure of the cyborg, this article argues that a more protean, flexible, and fluctuating understanding of legal personhood would offer both a more accurate and utopian conception of the body in law than the current essentialist approach found in a number of legal areas and particularly in English criminal law.
