His PhD (1958) was on "Self Defence in International Law".
He was highly esteemed as a lawyer: J. P. Gardner (Director of the British Institute of International and Comparative Law) wrote in the Introduction to Bowett's book International Court of Justice (1997), that his "….experience of international litigation is unrivalled…”
Career
Work in Beirut and for Egypt
He spent 1966–1968 in Beirut as Legal Adviser to the United Nations Relief and Works Agency for Palestinian Refugees (UNRWA). There he experienced, from a distance, the Six Day War and, much more directly, its effects in terms of the great increase in the number of refugees falling under UNRWA's remit. It coloured his attitude to the Middle East conflict thereafter: his rooms at Queens had on the walls photos of some of those refugees. In later years he successfully represented Egypt against Israel in a significant territorial dispute.
Work in Somalia
In 1964 while a Fellow of Queens' he was asked by the newly independent Government of Somalia to advise it on its territorial disputes with Ethiopia and Kenya. This was his first international law brief. On arrival in Mogadishu he was asked to draft a diplomatic note closing the British Embassy, on the basis that Britain was refusing to give effect to a plebiscite in the Northern Frontier District of Kenya, which had voted by a large majority to reunite with Somalia. Lacking experience in rupturing diplomatic relations, he asked to see the standard work, Satow's Guide to Diplomatic Practice. But the Somali Foreign Ministry had no books of any kind, and he was told to borrow it from the British Embassy. The book was duly returned, with a note of thanks and another, more formal, note giving the Ambassador four days to leave. It seems to have been a case of persona non grata sed liber gratus.
Personal life
While in his first job as a university lecturer at Manchester University, Bowett shared a house with three young women, including a "statuesque blonde with a sharp sense of humour", Betty Northall. Derek and Betty were married in 1953. [1][2][permanent dead link] Bowett was an avid tennis player and a big fan of Roger Federer.
