Oliver Lewis specialises in public law and human rights, with a focus on disability and mental health.

Responding to the Covid-19 crisis

While Oliver continues his Court of Protection and public law practice, during the Covid-19 crisis he is available to advise people with disabilities, their families and relevant public bodies (in the UK and abroad) on human rights-based solutions to the myriad of issues that the pandemic raises. His problem-solving approach enables him to provide rapid and practical advice and representation, including drafting judicial review pre-action correspondence. A recent example for the parents of an autistic man detained in a hospital force an NHS Trust which led the Trust to change its visits policy to take into account patients with disabilities.

Oliver’s blog on “Disability, coronavirus and international law” has been shared widely and is updated regularly. Oliver has held webinars on this topic and will adapt the material for webinars for disability rights NGOs on a pro bono basis. Commenting Oliver’s work in response to the crisis, a solicitor said, “I just wanted to say how impressive your constant work on Covid-19 changes and updates have been”, and a leading disability rights campaigner said, “Thank you for all the amazing actions you’ve already taken for people in my disabled community”.

Summary of legal practice

Oliver appears regularly in the Court of Protection in health and welfare cases, where he is instructed by the Official Solicitor, family members or public bodies. He has built up a particular expertise in cases concerning people with learning disabilities, autism or alcohol dependence and cases with allegations of abuse or neglect and cases involving complex family dynamics. He delivers training to social workers and allied practitioners on confident Court of Protection practice.

“Oliver is committed to protecting the rights of vulnerable people and will always provide advice based on that objective. He is always prepared and provides in-depth advice considering a range of options.” - Legal 500 2021

Oliver is regularly instructed in inquests that raise concerns about the provision of health or social care, often involving complex medical evidence. He is adept at judicially reviewing Coronial decisions to ensure that inquests are carried out fairly, as well as representation in civil claims.

Oliver is instructed in several ongoing inquests, including Article 2 and jury inquests that touch on learning disability, mental health, personality disorder, respiratory disorders, cardiology and neurology. He is representing several clients whose loved ones died from Covid-19 and where national and local failures arguably contributed to the deaths.

At the international level Oliver oversaw a third party intervention in Centre for Legal Resources v. Romania (2014), a case brought by a Romanian NGO in the European Court of Human Rights. This is a leading case on the right to life under Article 2 of the ECHR and access to justice for people with mental disabilities. The Court found that an NGO could pursue an application on behalf of a man who died in a psychiatric hospital and had no next of kin.

Clinical Negligence

Oliver accepts instructions in clinical negligence cases across the range of medical specialisms. He has an MA in Medical Ethics and Law and a PhD in mental capacity and international human rights. Oliver has a strong health-related inquest practice, as well as a Court of Protection and mental health law practice including serious medical treatment cases in which he is ranked as a leading junior. He sits as a chair of Independent Review Panels adjudicating NHS Continuing Healthcare appeals.

Oliver is developing a niche negligence practice in relation to the care and treatment of patients in mental health and learning disability institutional settings. These include in ‘assessment and treatment units’, some of which are private sector providers. This work involves both advice and representation to ensure that the detained person is discharged from detention in a timely and safe way and securing a care package in the community that meets the person’s needs. Oliver then works with families on HRA and negligence claims in relation to detention, seclusion, restraint and other forms of ill-treatment and trauma.

He has spent twenty years working with people with learning disabilities and/or autism and their families and is particularly sensitive to their needs. He is a trustee of the charity ‘Respond’, which provides psychotherapeutic interventions to people with learning disabilities and/or autism.

Administrative and Public Law

Oliver is regularly instructed to advise on judicial reviews, including those related to provision of healthcare and social care and compliance with the Equality Act 2010. Through drafting Letters Before Claim, Oliver has successfully reversed several case management decisions by Coroners. During the Covid-19 pandemic he has been instructed to challenge restrictive visits policies of NHS Trusts and care home providers. He is also instructed by the Covid-19 Bereaved Families for Justice, a group calling for a statutory inquiry into the UK government’s response.

International Human Rights Law

Oliver is currently instructed by the United Nations Development Program (UNDP) on an 18-month-long project about political participation of people with intellectual or psychosocial disabilities. He is drafting UNDP’s guidance to governments, electoral commissions and civil society on how to bolster participation in elections.

Oliver has carried out human rights monitoring and delivered training in over twenty countries in Europe, Africa, Asia and Latin America. Drawing on his experience as Legal Director then Executive Director of the international charity Validity (formerly the Mental Disability Advocacy Centre) from 2002 until 2017, he can be instructed to provide law and policy reform advice as well as training services to bodies committed to implementing human rights standards including governments, NGOs, inspectorates, philanthropic organisations, corporations and development agencies.

Oliver has litigated, trained and written about children’s rights, mental health law, monitoring closed institutions (e.g. social care institutions and psychiatric hospitals), equality and non-discrimination, community living, guardianship and legal capacity, political participation, access to justice, and combatting torture and ill-treatment – including sexual violence, psychiatric coercion and conditions of detention.

Bulgaria, 2008, European Committee of Social Rights). This case helped to ensure that abusive children’s institutions in Bulgaria were closed down. 

Oliver has developed and implemented advocacy strategies using international human rights mechanisms and the media. He is experienced in conducting negotiations with representatives of governments and intergovernmental organisations. Oliver has also facilitated complex and innovative multi-stakeholder discussions. For example, he worked to bring the disability and Roma rights communities together for the first time to advocate at the UN level for inclusive education for all children.

He has made many written and oral submissions to human rights bodies, including the UN Human Rights Committee, the UN Committee against Torture, the UN Subcommittee for the Prevention of Torture, the UN Committee on the Rights of the Child and the UN Committee on the Rights of Persons with Disabilities. He has advised several UN Special Rapporteurs (on Health and on Torture), and he has worked on projects with OHCHR, UNDP, UNICEF and the WHO.

In Europe, Oliver has conducted advocacy at the European Commission, the European Parliament, the Council of Europe’s Parliamentary Assembly, the Committee for the Prevention of Torture and the Commissioner for Human Rights. In 2011, he led a successful international campaign to persuade the Venice Commission to reverse its position that people could be deprived of the right to vote on the basis of their mental incapacity.
