I am a member of the Oxford Law Faculty (where I am a Visiting Professor), a Senior Research Associate at the Oxford Uehiro Centre for Practical Ethics (part of the Faculty of Philosophy), a Research Associate at the Ethox Centre (a multidisciplinary bioethics research centre within the Nuffield Department of Public Health, University of Oxford), a Research Associate at the Health, Law and Emerging Technologies Centre, (part of the Faculty of Law, University of Oxford), and an Associate at the Oxford Human Rights Hub. I am also a barrister, practising at 4-5 Gray’s Inn Square (where I specialize in medical law) and a part time judge of the Crown Court (where I am authorized to try serious sexual offences) and the County Court. I joined Exeter College as a Senior Supernumerary Fellow in 2022. I was previously a Fellow of Green Templeton College.

My PhD is from the University of Cambridge for work on the way that the law handles human autonomy and dignity in medical decision-making.

My research is a search for a satisfactory legal anthropology. I am concerned that we make decisions crucially affecting human welfare without having any real idea what sort of creatures we are. In the search for answers that will do real legal work I take cross-bearings from many perspectives and disciplines, including biology (I am particularly concerned with the moral status of non-human animals and what that status can tell us about our own status), moral philosophy, epistemology, neuroethics, and theology. I have concentrated my search in the field of medical law and ethics, and have written extensively about issues such as identity and personhood, the importance and limitation of the principle of autonomy, the meaning and use of the notion of human dignity, and the use of intuitions in moral and legal reasoning.

At the Bar I have been involved in some of the key cases in medical law, challenges in the European Court of Human Rights to the assisted dying regimes in France (Dignitas v France,  2023-2024) and Hungary  (Karsai v Hungary,  2023), the European Court of Human Rights to the Belgian law of euthanasia (Mortier v Belgium, 2022), the Supreme Court’s review of the requirement for court endorsement of the withdrawal of life-sustaining treatment from patients in prolonged disorders of consciousness (An NHS Trust v Y, 2018), the assisted suicide litigation in the Supreme Court (Nicklinson v Ministry of Justice, 2014), and the House of Lords (Purdy v DPP, 2009); the first prosecution of a doctor under the Female Genital Mutilation Act (R v Dharmasena 2015); Kadir v Mistry (2014) (principles governing the recoverability of damages for pain, suffering and loss of amenity in cases of delayed diagnosis); CP v The Criminal Injuries Compensation Authority (2014) (can a child in utero be the victim of a crime for the purposes of the CICA jurisdiction?); NHS Trust A v MB (a child) and Mr and Mrs B. (2006) (attempt by NHS Trust to withdraw life-sustaining artificial ventilation from a child with Spinal Muscular Atrophy); Al Hamwi v Johnston and North West London Hospitals NHS Trust (2005) (extent of clinician’s obligation to ensure that patient had understood warning about risks of amniocentesis); Halsey v Milton Keynes NHS Trust: Steel v Joy (2004) (effect on costs of a refusal to mediate); Kataria v Essex Strategic Health Authority (2004) (meaning of ‘review’; R v Chief Constable of West Mercia ex p Jepson (2003): Judicial review of police decision not to prosecute for late abortion of a child with cleft lip/palate; Leeds Teaching Hospitals NHS Trust v As, Bs and others (2003) (who is the father where the wrong embryo is implanted into a woman as a result of an IVF mix-up? The biological father or the husband of the woman?

I also undertake medical regulatory work, and was the Chambers and Partners Professional Discipline Junior of the Year in 2011. For many years I have been recognised as a leading practitioner in the fields of professional discipline and clinical negligence in the Chambers Directory of the Bar and the Legal 500.

From 2011-2018 I was the legal adviser to the Royal College of Physicians Committee for Ethics in Medicine, and was a member of the Royal College of Physicians Working Party on oral feeding difficulties and dilemmas.

I have written a number of texts for practitioners on medical law, personal injury litigation, advocacy, drafting, confidentiality and disclosure. I am the co-author of a program for the calculation of damages in personal injury cases.

I have also written 45 book chapters,  hundreds of academic and practitioner articles, and, to date, 144 blog posts, almost all of which deal with medical law and ethics. My blogs have appeared in, for instance, The Conversation and the University of Oxford Practical Ethics blog, and have an enormously wide readership.

My academic work has had considerable traction in the courtroom. Three examples:

In Re G (Children) [2012] EWCA Civ 1233, Munby LJ noted that:

‘Herring and Foster have argued persuasively (‘Welfare means rationality, virtue and altruism’, (2012) 32 Legal Studies 480), that behind a judicial determinations of welfare there lies an essentially Aristotelian notion of the ‘good life’….. The well-being of a child cannot be assessed in isolation. Human beings live within a network of relationships. Men and women are sociable beings. (...) As Herring and Foster comment, relationships
are central to our sense and understanding of ourselves. Our characters and understandings of ourselves from the earliest days are charted by reference to our relationships with others. It is only by considering the child's network of relationships that their well-being can be properly considered. So a child's relationships, both within and without the family, are always relevant to the child's interests; often they will be determinative.’

The arguments articulated in that Legal Studies article were material to the decision in Re
and, as the Court of Appeal acknowledged, have the potential to be widely and deeply

Munby LJ wrote a Foreword to my book Human Dignity in Bioethics and Law in which he
said, inter alia:

Three years ago, Charles Foster wrote an important book, Choosing Life, Choosing Death: The Tyranny of Autonomy in Medical Ethics and Law…. Now, he has written an even more significant book, Human Dignity in Bioethics and Law, which gives pride of place to dignity…. Dignity, as our author explains it, and autonomy, at least as traditionally understood in this country, stand potentially in stark conflict with each other. Can dignity trump autonomy? He asserts that it must and shows that it can. This is powerful
medicine indeed…. He asserts that since dignity is a deeper concept than autonomy, which is merely a manifestation of dignity, so where autonomy is in conflict with other second-order principles, such as justice, it is to the parent principle of dignity that we must have recourse in resolving the conflict. The argument is powerful and compelling…. Is dignity tough enough to pass the judicial assay? [Foster] asserts that it is, and, as it seems to me, succeeds in making good his case… He tests his thesis in a number of bioethical or medical contexts and, it may be thought, succeeds triumphantly in making good his thesis. We are all indebted to Charles Foster for giving us the privilege of pondering the implications of this profoundly important and, as it seems to me, ultimately convincing book....?’

Baker J, in the Oxford Shrieval Lecture 2016, noted that he approached questions of
medical ethics with trepidation ‘….conscious that this university is privileged to have a number of experts in the field. The writings of, for example, Prof Jonathan Herring and Charles Foster, amongst others, contain fascinating and sophisticated analyses of the many ethical issues that arise in these cases.’

I do a good deal of writing that would be classified as non-academic (although I don’t acknowledge any significant distinction between academic and non-academic writing). A recent example is Being a Beast, which is a New York Times Bestseller, was long-listed for the Baillie Gifford Prize (the ‘non-fiction Booker’) and the Wainwright Prize for Nature Writing, won the Deux Millions d’Amis literary prize (France), and the IgNobel prize for Biology in 2016.

That book, like most of my other non-academic writing, explores themes directly pertinent to my academic research (such as: Are humans special? How plastic is our identity? Can we know enough about the world to be able to make informed decisions?)

A sequel, Being a Human: Adventures in 40,000 years of consciousness (2021) examines three seismic epochs in the history of consciousness: the Upper Palaeolithic, the Neolithic and the Enlightenment.

My book The Screaming Sky (Little Toller, 2021) was shortlisted for the Wainwright Prize.

Recent and forthcoming non-academic books include a novel which seeks to recruit the voices of non-humans in telling a human story (Little Brown Sea, 2022, which was longlisted for the Runciman Award), a book of short stories (The Cry of the Wild: 2023: Doubleday/Penguin) which illustrates the challenges faced by various non-human species of living alongside us, an examination of contemporary apostasy (Faiths Lost and Found (with Martyn Percy): forthcoming: Darton Longman and Todd), and an examination of the relationship between humans and domestic animals (Pets and their People: forthcoming, Bodleian Publications).

My books have been translated into many languages, including French, German, Chinese, Japanese, Turkish, Czech, Spanish, Romanian, Italian, Dutch, Korean, Polish, Danish and Lithuanian.

I am currently working on a book about edge notions and edge people, to be published by Penguin, which will include a number of reflections on the role and efficacy of the law.

I contribute to many publications, including the Times Literary Supplement, the Guardian, the Times, and the Literary Review.
