Dr Leonard John Henry Arthur MB, BChir, MRCP, D Obst RCOG (20 April 1926 – 25 December 1983) was a British doctor tried in 1981 for the attempted murder of John Pearson, a newborn baby with Down Syndrome. He was acquitted.
An important test case, the trial brought to public attention the dilemmas for doctors in treating severely disabled newborn babies. Arthur felt strongly that doctors should always act in the best interests of the baby, with the full support of the parents. In some cases this meant not prolonging the baby’s life, in order to prevent future suffering. Opinion polls taken at the time of the trial indicated huge public support for Arthur’s approach. The outcome of the trial confirmed that ‘nursing care only’ is an acceptable form of treatment, and that administering a drug to relieve suffering is not an offence, even if it accelerates death. Ambiguities remain, however, about what is legally permissible in the treatment of disabled babies: if a doctor or anyone else intentionally kills a child, however disadvantaged, this would still be considered to be murder.
The descendant of Sir George Arthur, Arthur's father was a civil servant in India. In 1954 Arthur married Janet Stella Brain, daughter of Walter Russell Brain, a former president of the Royal College of Physicians made a baronet in 1954. Together they had one son and five daughters. There are coincidences in Leonard Arthur's family that relate to Down's syndrome. Arthur's mother-in-law, Janet Brain's mother, was Stella Langdon Down, the granddaughter of John Langdon Down who gave the first systematic description of Down's syndrome in 1867 and after whom the syndrome is named. Stella had a brother, John, who had Down's syndrome. He was named after his grandfather John Langdon Down, although he was born after his grandfather's death. 
After attending Aldenham School in Elstree, Hertfordshire, Arthur received an MB and BCh at Cambridge University. He did National Service on the front line in Korea, as a medical officer in support of the Durham Light Infantry. Post-registration posts followed in Birmingham, London, Newcastle and Plymouth, and he obtained the MRCP in 1957. He worked as a senior paediatric registrar in Ibadan, Nigeria and then in Bristol.
In 1965 he became a consultant paediatrician in Derby. He served on the Council of the British Paediatric Association, was secretary of the Paediatric Section of the Royal Society of Medicine and chaired the Trent Regional Advisory Sub-committee in Paediatrics, sitting also on the Regional Medical Committee. He also chaired a Derbyshire County Council Advisory Committee on children at risk of non-accidental injury. He was elected FRCP shortly before he died, aged 57, on 25 December (Christmas Day) 1983.
Arthur was described by a colleague as a "a kind, gentle, compassionate man who cared deeply for his patients and their families. A great supporter of the weak or poor, he was motivated by firm Christian beliefs". When he was suspended from work after his first court appearance, a petition with some 19,000 signatures, including three Derbyshire MPs, called for his reinstatement. A former patient wrote in 2001: "He was the very best doctor around. I know. I was one of his patients. And after all these years I still miss him."
John Pearson was born on 28 June 1980. He had Down’s syndrome and was later found to have had additional abnormalities of his lung, heart and brain. Shortly after the birth, Arthur talked to John Pearson’s parents and then wrote in the case notes, "Parents do not wish the baby to survive. Nursing care only." He prescribed DF118 (an opiate based painkiller), to be given ‘as required’ in doses of 5 mg at four hourly intervals. The baby died three days later, on 1 July 1980, the cause of death being identified as bronchopneumonia as a result of Down’s syndrome.
Arthur was subsequently charged with murder, but the possibility that the baby’s death was caused by his other defects caused the original charge to be reduced, during the trial, to attempted murder.
Sir Thomas Hetherington, Director of Public Prosecutions, described the decision to prosecute Arthur as the "most difficult" of his career. Arthur was tried on 5 November 1981 in Leicester Crown Court and defended by George Carman. Like Dr. John Bodkin Adams, Arthur did not give evidence in his own trial. His defence did call other distinguished expert witnesses though, such as Sir Douglas Black, then President of the Royal College of Physicians, who said:
"I say that it is ethical, in the case of a child suffering from Down’s, and with a parental wish that it should not survive, to terminate life providing other considerations are taken into account such as the status and ability of the parents to cope in a way that the child could otherwise have had a happy life."
Carman argued in his closing speech:
"He could, like Pontius Pilate, have washed his hands of the matter. He did not, because good doctors do not turn away. Are we to condemn him as a criminal because he helped two people [the mother and child] at the time of their greatest need? Are we to condemn a doctor because he cared?"
During the trial the Daily Mail published an opinion article about euthanasia by Malcolm Muggeridge, and was tried for contempt of court. Although the newspaper was aware the trial was going on, their defence was that the article was a discussion of public affairs under section 5 of the newly enacted Contempt of Court Act 1981. The House of Lords held that the article did create a substantial risk of serious prejudice to the trial but, as it was written in good faith to support a pro-life by-election candidate, and made no mention of the Arthur case, the risk of prejudice was merely incidental.
The case established that it was acceptable practice to prescribe ‘nursing care only’. It also confirmed the principle that "the administration of a drug by a doctor when it is necessary to relieve pain is a proper medical practice even when the doctor knows that the drugs will themselves cause the patient’s death".
M.J. Gunn and J.C. Smith are critical of the judge's summing up. Arthur had admitted to the police that the effect of the drug given, apart from being a sedative, was also to stop the child seeking sustenance and that this had been intended by him. A witness, Professor Campbell, concurred that this was a justifiable practice. The judge made no mention of this potential homicidal intent during the summing up however, something which has been criticised, amongst others, by Gerald Wright, QC.
