Josh Jackson is a specialist in human rights and international law, and is currently acting in high profile human rights cases before the High Court, courts in foreign jurisdictions, and the European Court of Human Rights. His expertise in human rights and international law informs and compliments other areas of his practice. Josh combines a practice at the Bar with active involvement in civil society, being a member of the Executive Committee of Action4Justice and the Steering Committee of the ETO Consortium. He is dedicated to using law to generate social impact at home and abroad.

Human Rights & Public International Law

Josh acts for claimants in human rights and international law matters. He is instructed on behalf of six Portuguese children in the climate case of Duarte Agostinho & Ors v Portugal & 32 Other States before the European Court of Human Rights. He has worked with Schona Jolly QC on three cases going to the European Court of Human Rights involving complex issues of public international law, such as State Immunity and the rules of Statehood under customary international law.

Josh advises on human rights and international law claims in foreign jurisdictions. He has advised on international law issues arising from the construction of a power station on the Israeli/West Bank border. He is instructed in Thomas & Quadad v Attorney General to advise on a challenge to oil and gas exploration based on the constitutional right to a healthy environment in Guyana.

Employment & Discrimination

Josh primarily acts for claimants. He is acting in unfair dismissal, discrimination, working time, whistleblowing, health and safety, minimum wage, and trade union claims. For example, he is instructed by IWGB on behalf of foster carers in Johnstone & Johnstone v Glasgow City Council in whistleblowing claims following the landmark EAT judgment they had employee status in 2020.

Josh has worked closely with members of chambers in a mass group claim involving questions of worker status. He assisted Chris Milsom in Steer v Stormsure before the Employment Appeal Tribunal and Court of Appeal regarding the compatibility of the absence of interim relief under the Equality Act with the ECHR, and the application of section 3 of the Human Rights Act therein.

Public & Administrative Law

Josh acts for claimants in judicial reviews. He acts for the Claimants in R (Peters and Findley) v Secretary of State for Health and Social Care (led by Ed Williams QC), challenging the mandatory vaccination requirement for care workers. During pupillage, Josh gained experience with Tom Brown in judicial reviews regarding the transposition of EU health and safety directives, and in unlawful detention cases.

Josh co-drafted the Administrative Law Bar Association’s response to the Independent Human Rights Act Review. He has acted for claimants in social security appeals before the Upper Tribunal and represents detainees in immigration bail hearings on behalf of BID.

Personal Injury, Tort Law & Corporate Accountability

Josh acts for claimants in a range of tortious claims with an employment or human rights dimension. He is building a practice in claims against public authorities, employers’ liability cases, modern slavery and human trafficking claims, and business and human rights cases.

Josh has assisted Dan Lawson and Anna Beale in complex employers’ liability cases. He was instructed alongside Anna Beale in a civil claim against human traffickers outside of jurisdiction. He has co-authored a Handbook on business and human rights, and has advised on the prospects of bringing a claim in English Courts regarding an oil spill off the Colombian coast.

Prior to Cloisters

Prior to becoming a barrister Josh worked as a project manager at Action4Justice, where he helped develop access to justice platforms in different countries and authored guidebooks on public interest litigation. Previously, he spent a year as an intern in Greenpeace International's legal team, where he assisted on climate litigation in several jurisdictions.

Josh has working proficiency in Spanish.
