This document discusses issues relating to capacity to consent to relationships and sexual activity. It examines legal cases that have addressed when public authorities can intervene in such decisions and how to balance protection versus autonomy. While the MCA prohibits proxy decisions about marriage or sexual relations, courts have found capacity relates to the type of activity, not the specific person. As long as a person can understand the nature and consequences of the sexual act, they have capacity, even if they make unwise choices. Situation and coercion can impact decision making ability in some cases. The intention is to allow people to make their own decisions to the greatest extent possible.
