Dennis J. Baker (King's College London - School of Law) has posted The Moral Limits of Consent as a Defense in the Criminal Law on SSRN. Here is the abstract:
In this paper I aim to examine the objective limitations of consent as a defense to criminal harm doing. This paper starts by briefly outlining the idea of objective morality (critical morality) as the proper basis for criminalization decisions and argues that there are also objective rather than mere conventional reasons (positive morality) for limiting the scope of consent as a defense in the criminal law. The idea of consent is in itself an objective reason for excusing wrongful harm doing to others. However, it can be overridden by other objective considerations of greater importance. In this paper, I argue that it is only wrongful harm doing that is criminalizable, as we do not criminalize mere accidents. Furthermore, I argue that a person can as an exercise of her personal autonomy consent to certain harms. However, there is a crucial difference between waiving rights that are grounded in an exercise of personal autonomy and waiving rights that violate a person's human dignity: rational autonomy. I conclude that regardless of consent, certain grave harms violate a person's dignity as a human being and therefore are wrongful and criminalizable.
