To what extent should an individual be free to determine his or her own decisions, and when is it acceptable for the state to impose restrictions upon individual choice? The answers to these questions are complex and require an exploration of concepts such as ‘liberty’ and ‘autonomy’. The aim of this chapter is to determine the extent to which an individual should be free to make his or her own choices, by considering when state intervention in individual decision-making is acceptable, and to consider how this approach may apply to reproductive decision-making.
