In this shedinar, I talk to Julian Sheather, special adviser in ethics and human rights to the British Medical Association. Amongst other topics we look at decision-making in relation to older adolescents, and grapple with some of the ethical underpinnings to the Mental Capacity Act 2005 (also features cameo from my son in the background).

For my take, with Camillia Kong, on some of the relationship between law and ethics in the context of the MCA 2005, you may want to have a look at this book.
