Barder was British Ambassador to Ethiopia during the Ethiopian famine of 1984-85. He played a key role in making possible the deployment of the Royal Air Force to Ethiopia for 14 months to move relief supplies from the ports to remote parts of the country where it was urgently needed. His role in the relief effort is described in The Ethiopian Famine, and A Year In The Death of Africa. In 2009 he took part in a BBC Radio 4 programme which brought together some of the key people involved in the Ethiopian famine including International Red Cross nurse Claire Bertschinger ; BBC reporter Michael Buerk; Dawit Wolde Giorgis, former head of the Ethiopian Relief and Rehabilitation Commission; and Hugh Goyder, former head of Oxfam's Ethiopia programme.
Resignation from the Special Immigration Appeals Commission
Barder was appointed to the Special Immigration Appeals Commission in November 1997, three years after his retirement from the diplomatic service. He resigned in January 2004 when the Government extended the role of SIAC in a way which he believed to be contrary to Britain's international obligations. He set out the reasons for his resignation in the London Review of Books and in The Guardian. The Anti-terrorism, Crime and Security Act of 2001 made SIAC additionally responsible for hearing appeals by persons indefinitely detained without trial by the Home Secretary on suspicion of being connected with terrorism but who could not be deported because there was no country to which they could safely be sent. Barder took the view, subsequently endorsed by the Law Lords, that sending people to prison indefinitely and without trial and without even being charged with any offence was a breach of Britain's obligations under the European Convention on Human Rights and the Human Rights Act 1998. On 16 December 2004 the Law Lords ruled that Part 4 was indeed incompatible with the European Convention on Human Rights, but under the terms of the Human Rights Act 1998 it remained in force. It has since been replaced by the Prevention of Terrorism Act 2005.
Blogging and publications
After retiring from the Diplomatic Service, Barder wrote a popular blog and was a regular contributor to the LabourList website. He had articles and letters published in The Political Quarterly, London Review of Books, Prospect, The Times, The Guardian, The Hague Journal of Diplomacy, and elsewhere. He was Editorial Consultant for A Dictionary of Diplomacy and contributed to the Third Edition of Fowler's Modern English Usage. Barder's book, What Diplomats Do: The Life and Work of Diplomats was published in July 2014. Not a diplomatic memoir, it describes a diplomat's day-to-day life and work through a typical but fictitious diplomatic career. It has been described as "massively authoritative, and original... a brilliant book" ; "excellent... I found reading its chapters irresistible, like eating peanuts".
