With contributions from an international team of experts, this collection provides a much-needed international, comparative approach to mental capacity law. The book focuses particularly on exploring substantive commonalities and divergences in normative orientation and practical application embedded in different legal frameworks. It draws together contributions from eleven different jurisdictions across Europe, Asia and the UK and explores what productive or unproductive values and practices currently exist. By providing a detailed comparison of how legal and ethical commitments to persons with disabilities are framed in capacity law across different national systems, the book highlights the values and practices that could lead to changes that better respect persons with disabilities in mental capacity regimes.
