Author Q&A

In your opinion, which is the most fascinating entry in your dictionary and why?

The most fascinating entries are those which include the word ‘reasonable’. The courts have often struggled with the concept as what is reasonable to one party in a dispute is unreasonable to the other party. In the famous case of Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1KB 223 (CA) the court managed to come up with a definition of unreasonable.

When we look at ‘reasonable’, not in the context of public bodies but in the actions of individuals the views on reasonableness are very wide. What is 'reasonable force' has been argued frequently on a case by case basis. What is a ‘reasonable person’ is clearly open to debate. Perhaps the most glaring arguments arise from the divorce cases regarding what is a ‘reasonable financial provision’. Needing vast amounts of maintenance because Kensington is the only place in which the claimant can reasonably live, may seem reasonable to the claimant, but perhaps not the 'reasonable person’ - the ‘man on the Clapham omnibus’.

What would you say is the most unusual/obscure term in your subject area?

Idiopathic. The dictionary is inter alia, intended to assist investigators and others in understanding reports received from doctors, pathologists, and forensic anthropologists. The word crops up in reports on describing conditions and diseases. A forensic anthropologist examining skeletal remains may describe the condition of DISH, (Diffuse Idiopathic Skeletal Hyperostosis). The investigator wants to know is ‘what caused it’ - ‘idiopathic' means ‘I don’t know’.

What is the one term or concept that everyone—from students to everyday web users—should be familiar with? Why?

Natural justice, and police officers should implement this using the ‘discretion’ they have on how and when to take legal action. If laws are automatically enforced and any attempt is made to fetter the discretion of constables, policing with consent will be threatened and the police seen as an arm of the state. As Churchill said 'All the great things are simple, and many can be expressed in a single word: freedom, justice, honor, duty, mercy, hope'.
