John Aneurin Grey Griffith, FBA (14 October 1918 – 8 May 2010) was a Welsh legal scholar who spent much of his academic career within the Faculty of Law of the London School of Economics and Political Science.

[1] He was a member of the Peace Pledge Union and initially registered as a conscientious objector during the Second World War, serving two years in the Royal Army Medical Corps.

[2] He unregistered as conscientious objector and began officer training in the Indian Army, serving a further two years and left in 1946 as a major.

[3] Griffith's legal works, according to Martin Loughlin, "subverted the self-satisfied liberal-democratic view about the nature and functioning of the constitution, replacing it with a more realistic “what actually happens” account...his more explicitly political analyses tended to highlight the authoritarian nature of government and in particular the close political, social and class linkages of the elites in power".

[3] Griffith believed that the idea of "the rule of law" was "a fantasy invented by Liberals of the old school in the late-19th century and patented by the Tories to throw a protective sanctity around certain legal and political institutions and principles which they wish to preserve at any cost".
