Inquests in England and Wales are held into sudden or unexplained deaths and also into the circumstances of and discovery of a certain class of valuable artefacts known as "treasure trove". In England and Wales, inquests are the responsibility of a coroner, who operates under the jurisdiction of the Coroners and Justice Act 2009. In some circumstances where an inquest cannot view or hear all the evidence, it may be suspended and a public inquiry held with the consent of the Home Secretary.
