Jonathan Philip Chadwick Sumption, Baron Sumption, medieval historian and former senior judge who sat on the Supreme Court of the United Kingdom between 2012 and 2018. Sumption was sworn in as a Justice of the Supreme Court on 11 January 2012, succeeding Lawrence Collins, Baron Collins of Mapesbury. Exceptionally, he was appointed to the Supreme Court directly from the practising Bar, without having been a full-time judge. He retired from the Supreme Court on 9 December 2018 upon reaching the mandatory retirement age of 70.(born 9 December 1948), is a British author,
Sumption is well known for his role as a barrister in many legal cases. They include appearances in the Hutton Inquiry on HM Government's behalf, in the Three Rivers case, his representation of former Cabinet Minister Stephen Byers and the Department for Transport in the Railtrack private shareholders' action against the British Government in 2005, for defending HM Government in an appeal hearing brought by Binyam Mohamed, and for successfully defending Russian billionaire Roman Abramovich in a private lawsuit brought by Russian oligarch Boris Berezovsky.
A former academic, Sumption was appointed an Officer of the Order of the British Empire (OBE) in the 2003 New Year Honours and is also known for writing a substantial narrative history of the Hundred Years' War, so far in four volumes. Sumption has been elected a Fellow of the Royal Historical Society (FRHistS) and a Fellow of the Society of Antiquaries of London (FSA).
Early life and education
Jonathan Sumption was born on 9 December 1948. He is the eldest of the four children of Anthony Sumption, a decorated naval officer and barrister, and Hilda Hedigan; their marriage was dissolved in 1979. He was educated at Eton College, where at 15 he was at the bottom of his class. He read Medieval History at Magdalen College, Oxford, from 1967 to 1970, graduating with a first. He was elected a fellow of Magdalen College, teaching and writing books on medieval history from 1971 to 1975 before leaving to pursue a career in law. Called to the Bar at the Inner Temple in 1975, he then pursued a successful legal practice in commercial law.
In the 1970s, Sumption served as an adviser to the Conservative MP and Cabinet Minister Keith Joseph. In 1974 Joseph and Margaret Thatcher together founded the Centre for Policy Studies to act as a think tank for the Conservative Party, and Sumption became one of its earliest employees, working as a speechwriter for Joseph. Sumption and Joseph co-wrote a 1979 book, Equality, seeking to show that "no convincing arguments for an equal society have ever been advanced" and that "no such society has ever been successfully created".
In the late 1970s Sumption was a regular contributor to The Sunday Telegraph.
Sumption was appointed Queen's Counsel (QC) in 1986 at the relatively young age of 38, and elected a Bencher of the Inner Temple in 1991. He has served as a Deputy High Court Judge in the Chancery Division, and a Judge of the Court of Appeal of Jersey and the Guernsey Court of Appeal.
On 30 November 2007, when a practising barrister, Sumption successfully represented himself before Mr Justice Collins in a judicial review application in the Administrative Court concerning proposed development near his home at Greenwich.
Earnings as a barrister
The Guardian once described him as being a member of the "million-a-year club", the elite group of barristers earning over a million pounds a year. In a letter to The Guardian in 2001, he compared his "puny £1.6 million a year" to the vastly larger amounts that comparable individuals in business, sports and entertainment are paid.
For a four-week trial (and all the preparatory work) in the UK in 2005 he charged £800,000 to represent HM Government in the largest class action in the UK, brought by 49,500 private shareholders of the collapsed national railway infrastructure company Railtrack. The Government had money and reputation at stake, the case examining some of the actions of HM Government, especially of former Transport Secretary Stephen Byers. Byers became the only former Cabinet Minister to be cross-examined in the High Court in relation to his actions in modern times: the British Government won the case.
On 4 May 2011 Sumption's appointment as a Justice of the Supreme Court was announced. Upon his subsequent swearing-in on 11 January 2012, he assumed the title of Lord Sumption pursuant to a Royal Warrant (by which all members of the Supreme Court, even if they do not hold a peerage title, are accorded the style of "Lord" for life). Sumption was sworn of the Privy Council on 14 December 2011 in advance of his joining the Court, whose Justices also serve as members of the Judicial Committee of the Privy Council. He retired from the Supreme Court on 9 December 2018. Although as a retired justice of the Supreme Court he would have been eligible for appointment to its Supplementary Panel, he was not so appointed.
Sumption is the first lawyer appointed to the Supreme Court without previously serving as a full-time judge since its inception in 2009. There were only five such appointments as Law Lords to the Court's predecessor, the Appellate Committee of the House of Lords. Two were Scots lawyers: Lord Macmillan in 1930 and Lord Reid in 1948; the others were: Lord Macnaghten (1887), Lord Carson (1921) and Lord Radcliffe (1949).
After his retirement, Sumption was appointed as a Non-Permanent Judge of the Court of Final Appeal in Hong Kong on 13 December 2019 by Hong Kong Chief Executive Carrie Lam. After making his pledge of allegiance to the Hong Kong SAR of the People’s Republic of China as part of the judicial oath, Lord Sumption officially commenced his office as a Hong Kong judge on 18 December 2019. He had previously appeared as counsel in the Court of Final Appeal in a number of cases.
The Hundred Years' War
Sumption's narrative history of the Hundred Years' War between England and France (of which four volumes have so far been published, between 1990 and 2015) has been widely praised as "earning a place alongside Steven Runciman's A History of the Crusades" according to Frederic Raphael, and as a work that "deploys an enormous variety of documentary material ... and interprets it with imaginative and intelligent sympathy" and is "elegantly written" (Rosamond McKitterick, Evening Standard); for Allan Massie it is "An enterprise on a truly Victorian scale ... What is most impressive about this work, apart from the author's mastery of his material and his deployment of it, is his political intelligence".
Five volumes are planned. Volume I (covering the years from the funeral of Charles IV of France in 1329 to the Surrender of Calais in 1347) was first published in 1990. Volume II (covering the years from 1347 to 1369) was published in 1999. Volume III (covering the years from 1369 to 1399) appeared in 2009. Volume IV (covering the years from 1399 to 1422) appeared in 2015, the 600th anniversary of the Battle of Agincourt.
Sumption has been praised for a clipped and polished prose style, which he credits to his unwillingness to employ cliché. He admires Gibbon but points out "if anybody wrote like him today they’d be dismissed as a pompous fart".
Sumption has been described as "conservative neo-liberal and libertarian." In 1974, he worked with Conservative MP Keith Joseph at the Centre for Policy Studies, a Conservative Party think-tank. However, he was a Labour supporter at the time and later voted for Tony Blair.
He has said that that an attempt to rapidly achieve gender equality in the Supreme Court through quotas or positive discrimination could end up discouraging the best applicants, as they would no longer believe that the process would select on merit, and "have appalling consequences for justice". He has criticised the judicial appointments process in the United States, where politicians quiz judicial appointees on their views, as "discreditable" and described former Attorney General for England & Wales Geoffrey Cox's proposal for a similar system as, "one of the most ill-thought-out ideas ever to emerge from a resentful government frustrated by its inability to do whatever it likes".
He has criticised the historical curriculum in English schools as "appallingly narrow", warning that by forcing English schoolchildren to study 1918–1945 in isolation they "are being taught about Germany and Europe during its most aberrant period". He believes that history should not be apologised for once perpetrators of injustices are no longer alive, describing apologies for events such as the Irish Famine and the Armenian Genocide as "morally worthless", although saying that, "we have a duty to understand why things happened as they did" and there are "lessons to be learned". In the wake of Black Lives Matter activity following the death of George Floyd in May 2020 in Minneapolis, the United States, Sumption criticised the removal of historical symbols because the people of the past did not share the values of the present as, "an irrational and absurd thing to do".
He voted to remain in the European Union in the 2016 referendum, describing the decision to leave as, "a serious mistake that will do lasting damage to our economy" and that, "Britain will be dominated by the European Union whether we belong to it or not". Nevertheless, he believed there were strong arguments for Brexit on the grounds of national sovereignty and identity. He said that leavers, "were not mad. They are not irrational, not naive and have not been deceived". He wrote that, "All of these patronising explanations of their decision seems to me to be mere attempts to evade unpalatable truths."
Judicial Interference in Politics
Sumption has written in detail about his concerns regarding the relationship between the judiciary and politics in several lectures and books, most notably his books Trials of the State: Law and the Decline of Politics (2019) and Law in a Time of Crisis (2021). He argues that since the 1960s, but particularly in recent years, the courts have undermined the political processes and institutions of parliament by judging issues that should be decided by elected politicians and ministers. He specifically critiques the expansion of judicial review, saying that, "It has tended to intrude into to areas that belong to parliament and ministers answerable to parliament", and has criticised the interpretative powers conferred by the Human Rights Act 1998. He argues that political figures are more democratically accountable to the public for decisions they make, unlike judges who are unelected and difficult to remove from office. He has criticised the European Court of Human Rights, which interprets and adjudicates on the European Convention on Human Rights. He has compared the values of the Strasbourg court and those of the post-war dictatorships of eastern Europe, stating that "they both employ the concept of democracy as a generalised term of approval for a set of political values". He describes the text of the Convention as "wholly admirable" but argues that the Strasburg court has interpreted and developed the rights very broadly to go beyond their original meaning and to the extent that the rights cover issues which are properly the remit of elected legislatures. He has criticised the "living instrument" doctrine, particularly regarding Article 8 of the Convention, which he describes as, "the most striking example of this kind of mission creep." He has said that if there was no significant change in the approach of the Strasburg court then he would support withdrawing from the Convention.

Sumption has been highly critical of the British government's use of lockdown to curb the COVID-19 pandemic, arguing against restrictions on the public, in defence of the rights and civil liberties of the private individual. As he is a former Supreme Court judge, Sumption's criticism is a notable addition to the views of other high-profile critics such as Peter Hitchens and Toby Young. On 30 March 2020, Sumption gave an interview on The World at One about the then recently implemented full restrictive lockdown on the population on 23 March 2020. He argued that the full restrictive lockdown would have serious negative consequences as a result of restricting civil liberties, locking down a healthy population, and stalling a healthy economy. He questioned whether the virus was serious enough to "warrant putting most of the population into house imprisonment, wrecking our economy for an indefinite period, destroying businesses that honest and hard-working people have taken years to build up, saddling future generations with debt?" He argued that the lockdown would have serious health costs on many people causing "unbelievable distress inflicted on millions of people who are not especially vulnerable and will suffer only mild symptoms or none at all, like the Health Secretary and the Prime Minister". For these reasons, Sumption believes the lockdown as a 'cure' for the virus may be worse than the effects of the actual virus.
He has criticised the actions of the police forces during the lockdown measures because he argued that they followed the wishes of ministers instead of just the law, when the ministers themselves were simply reacting to public pressure in applying stringent lockdown measures. Furthermore, in The Sunday Times of 17 May 2020 he remarked that "Free people make mistakes and willingly take risks. If we hold politicians responsible for everything that goes wrong, they will take away our liberty so that nothing can go wrong. They will do this not for our protection against risk, but for their own protection against criticism". In The Spectator, he wrote of his concerns that Britain risked becoming a 'police state' and queried whether the "severe" police reaction was justified.
In a podcast interview in July 2020, Sumption claimed evidence existed indicating the virus was very mild compared to other pandemics in the 20th century. He said a Cabinet Office paper which showed pandemics in the 20th century with the Coronavirus at the lowest in terms of infectiousness and mortality levels. He argued that a coronavirus inquiry is needed because there will be worse pandemics in the future. In the same interview he also added that MPs had privately thanked him for speaking out against the lockdown but did not "dare open their mouths” to publicly speak out about it.
Sumption has argued that the lockdown response to the pandemic could threaten democracy. He has said this is because people have been giving up their liberties because of their fear of the virus, and despotisms arise not because liberty is forcibly taken away by tyrants but because people voluntarily surrender their liberty in return for protection from some perceived threat and it’s in the interests of governments to exaggerate that threat in order to procure compliance.
Furthermore, he has noted that advocates of human rights “have been extraordinarily silent” about the lockdown. Sumption has said that his view on the virus vindicate the views he expressed in his Reith lectures and in his book Trials of the State: Law and the Decline of Politics (2019) which was "remarkably prescient" about it.
In a podcast aired on 10 September 2020, Sumption told journalist Allison Pearson of The Daily Telegraph that the "lockdown and the quarantine rules and most of the other regulations have been made under the Public Health (Control of Disease) Act 1984", not the Coronavirus Act 2020 itself. Sumption further observed that the only language contained in this Act which confers specific powers over an individual's liberty relate to individuals who are believed "on reasonable grounds" to have contracted an infectious agent, and that thus the powers purported by the Johnson government to enforce lockdown measures on the whole population are in fact ultra vires and of vanishing effect on the vast majority. He found the deliberate employment of this Act to enforce a lockdown a "drastic decision" and "profoundly controversial".
On 13 September 2020, Sumption told Tom Swarbrick on LBC′s Sunday show that he thought the new coronavirus social distancing policy of rule of six was unenforceable: "You can enforce it if you're sufficiently intrusive – you can put spies on every street, you can have marshals watching through windows but unless you do that people are not going to respect it unless they think it's a good idea."
On 27 October 2020, Sumption delivered at University of Cambridge the annual Freshfields lecture, which he entitled "Government by decree - COVID-19 and the Constitution". In it, he decried the executive's bypassing of Parliament via the Public Health Act 1984, which allowed it to introduce lockdowns and other measures without scrutiny. He expanded by stating that the executive gave police unprecedented discretionary enforcement powers, some of which were used to suppress opposition to its policies, including via new quasi-criminal offences brought into being on the 'mere say-so of ministers', with fines of up to £10,000, through the 'language of impending doom... alarmist projections and statistical manipulation'.
On 17 January 2021, Sumption appeared on The Big Questions to discuss the question of whether the lockdown was "punishing too many for the greater good". Sumption put across the argument that the death of a young person had greater cost to society due to the amount of potential years of life lost, in comparison to an older person who had fewer years of life remaining. He made this argument in reference to the 'axiomatic' and widely used evaluations made in medical intervention (quality-adjusted life year). This formed part of his argument that only the "old and vulnerable" should isolate. Sumption also argued that the governments actions had "virtually no impact" on mortality rates, since lockdowns simply 'push' deaths forward into the period when society opens up. Thus he believes the only legitimate justification for a lockdown is to buy time to prepare the health service. Sumptions views were the subject to a heated debate on the program.
Sumption met Teresa Whelan at his sixth birthday party and they later married shortly after he graduated from Oxford. They have two daughters, one son, and five grandchildren. He lives in Greenwich and has a second home, a chateau in the village of Berbiguières in the south of France.
Sumption speaks French and Italian fluently, and reads Spanish, Dutch, Portuguese, Catalan, and Latin. He "rarely learned them using guides, instead I preferred to muddle on through a text with a dictionary by my side".
