Professor Steven Haines

Professor of Public International Law

I was appointed to the Chair in Public International Law in the University of Greenwich in September 2012, since when I have also been a Visiting Fellow on the University of Oxford's Changing Character of War Programme (2012-13), a Visiting Professor in Security and Law at the Swiss Federal Institute of Technology (ETH) in Zurich (2010-15), and a Senior Research Fellow of the Centre for Rising Powers in the University of Cambridge (2012-2018).  I am currently a Senior Associate Fellow of the Royal United Services Institute for Defence and Security Studies (RUSI).

My full-time academic career (since 2003) has built substantially on previous service in the British Armed Forces.  I left the Ministry of Defence Central Policy Staff in 2003 to Head a Politics and International Relations department within the University of London and was subsequently (2006) promoted to a Chair in Strategy and the Law of Military Operations.  In 2008 I accepted a post as an academic international lawyer in Geneva, focused principally on the international law governing international security operations, in particular International Humanitarian Law (IHL).

I was Head of the Security and Law Programme at the Geneva Centre for Security Policy and a member of its Management Board.  I also taught at the Geneva Academy of IHL and Human Rights, on its LLM Programme.  In terms of pro bono work, I have been Legal and Military Consultant to the Global Coalition to Protect Education from Attack since 2011, writing international Guidelines for the Protection of Education from Military Use which have to date been formally endorsed by 84 states, including the UK. I am also a Trustee of the NGO Human Rights at Sea, the Chair of Save the Children International's Civil-Military Advisory Board, and a Trustee of the Naval Review

Prior to my full-time academic career, I was an officer in the Royal Navy, serving at sea in a variety of surface warships, deploying to the South Atlantic, the Caribbean, the Mediterranean, Indian and Pacific Oceans.  Operationally, I served on UN mandated economic embargo operations, spent over four years with the Northern Ireland Security Forces (latterly as the Head of Operations in the naval HQ in Belfast), and served as a British Sea Fisheries Officer for three years enforcing fisheries regulations in Britain's Extended Fisheries Zone.  

In 2001 I deployed to the British led NATO Multi-National Brigade in Pristina, Kosovo and to the British Joint Task Force HQ in Freetown towards the end of the civil war in Sierra Leone.  Staff appointments included the Management Board of HM Naval Base Portland and the Executive Board of the Armed Forces' 'think-tank' at Shrivenham (having been the RN member of the Ministry of Defence's Strategic Development Study that recommended its establishment). I spent a total of eight years in the Ministry of Defence, on the Naval Staff (1995-98) and on the Central Policy Staff (1998-2003). 

I was the author of both the RN's strategic doctrine (British Maritime Doctrine, 1999) and the over-arching doctrine for the Armed Forces (British Defence Doctrine, 2001).  I compiled the RN's Handbook on the Law of Maritime Operations used by deployed units during the invasion of Iraq in 2003 and was the Chair of the Editorial Board of the official Manual of the Law of Armed Conflict (OUP, 2004), being also joint author of its chapter on 'Maritime Warfare'.

Research / Scholarly interests

I have an inter-disciplinary approach to my research which principally utilises law, politics, international relations, security studies and history, my main aim being to examine legal aspects of international security within broader historical and policy contexts.  I have held university appointments, including at professorial level, in both Public International Law and International Relations/Security Studies.  In the past I have had a deep specialist interest in the law governing the conduct of military and international security operations, including International Humanitarian Law/the Law of Armed Conflict. When I moved to Greenwich in 2012, while retaining these specialist legal interests, I decided to re-focus my research under the general heading of Ocean Governance, including the Law of the Sea and issues to do with maritime security and the maintenance of law, order and security at sea. The bulk of my research is currently focused on the preparation of a substantial monograph, on the compiling of an extensive and comprehensive academic research handbook, and on an edited volume assessing the work of an important British naval strategic thinker who died in 2017 (Rear Admiral Richard Hill).

  • My monograph, provisionally entitled The End of the Grotian Era: The Transition in Ocean Governance from Mare Liberum to Mare Legitimum 1600-2050, traces the development of ocean governance from the 17th Century to the 21st, arguing that the previous devotion to the 'Freedom of the Seas' (or Mare Liberum), while arguably a sensible and workable arrangement in the past, has now become profoundly inappropriate as a means of ensuring good governance at sea. The middle of the 20th Century was a major turning point that seems to have signalled the end of one era and the beginnings of another. I am arguing that the previous reliance on Mare Liberum as the underpinning principal should give way to a new focus on Mare Legitimum (or 'lawful seas'). This monograph is in preparation for planned publication in 2020.  It will be submitted as a formal proposal to OUP (who are aware of this) as soon as I have determined a firm and realistic completion date.  (It will be submitted for the forthcoming REF.)
  • The research handbook (The Oxford Handbook of Ocean Governance), has been through external peer review and is about to be submitted for formal OUP contractual decision.  It will be a comprehensive and authoritative assessment of the current state of ocean governance, bringing together a total of around fifty authors contributing just under sixty chapters in all.  I initiated this project and chair an Editorial team consisting of four distinguished co-Editors (based in Chile, Canada and the UK) and two Associate Editors. Publication is being planned for around 2021/22.
  • The volume on maritime strategy is provisionally entitled Maritime Strategy for Medium Powers in the 21st Century: Richard Hill's Strategic Thinking Re-Visited.  Discussions have already been conducted with leading publishers in the UK and the US and a full proposal will be submitted once work on the volume has taken shape.  The volume will be the product of a collaboration between leading naval thinkers in the UK, Australia, India, Chile, Japan, Canada, and the US, all of whom are currently participating in a series of workshops each dealing with an important element of the work under review.  Financial support has been provided to the project from the Hudson Trust in Oxford and the Australian Se Power Centre.  The project is being run jointly by me and Rear Admiral James Goldrick of the Royal Australian Navy, with a projected publication date of 2020.

I am always interested in hearing from potential post-graduate research students who wish to conduct research in relation to ocean governance, especially with a maritime security dimension. I currently have four research students working with me, three focused on issues relating to maritime security and one researching the international legal framework for counter-terrorism. I would be especially interested in any scholar who would like to conduct his/her research on the Law of Armed Conflict Applicable at Sea and on the military and constabulary roles of navies within the international system generally.
