At the end of June 1931, Pritt represented Bell and Snelling in Bell v Lever Bros Ltd, a landmark case establishing the principles for common mistake in common law. His "skill and tenacity" was an important reason why Bell and Snelling succeeded. In 1931, Pritt represented three
Indian revolutionaries,
Bhagat Singh,
Sukhdev Thapar and
Shivaram Rajguru before the
Privy Council, arguing that the ordinance which had been used to establish a
special tribunal to try them for the crime of murdering a
policeman was
ultra vires. The appeal was rejected, and the three men were executed by
hanging within a month of their trial on 23 March 1931. Pritt successfully defended
Ho Chi Minh in 1931 against a French request for his extradition from
Hong Kong. In 1933, Pritt was chairman of the "International Commission of Inquiry into the Clarification of the Reichstag Fire", the so-called "London Counter-Process" to the Leipzig Reichstag Fire Process. In 1942, he initially defended
Gordon Cummins but, due to a technicality, the trial was abandoned and restarted with a new jury, and Pritt was replaced by another lawyer. Cummins, then a serving member of the
Royal Air Force, was known in the press as the
Blackout Ripper and was accused of murdering four women, mutilating their bodies and attempting to murder two others. The defence was unsuccessful, a subsequent appeal was dismissed and Cummins was hanged in June 1942. Pritt's most high-profile case, which he lost, was defending the
Kapenguria Six, a group of Kenyan political figures accused in 1952 of links with the
Mau Mau:
Jomo Kenyatta,
Bildad Kaggia,
Kung’u Karumba,
Fred Kubai,
Paul Ngei and
Achieng Oneko. In this case, Pritt worked with a team of African, Indian and Afro-Caribbean lawyers including
Achhroo Ram Kapila,
H. O. Davies,
Dudley Thompson and
Fitz Remedios Santana de Souza. Pritt played a significant role in the
Singaporean
"Fajar trial" in May 1954. He was the lead counsel of the
University Socialist Club with the assistance of
Lee Kuan Yew as the junior counsel and helped the club to win the case eventually. From 1965 to 1966, he was Professor of Law at the
University of Ghana. Strachan then went onto be elected the President of Inner London Justices' Clerks' Society, and became an expert in laws regarding adoption, marriage, and drink driving. ==Death and legacy==
