A procurator fiscal (pl. procurators fiscal), sometimes called PF or fiscal, (Neach-casaid a' Chrùin) is a public prosecutor in Scotland, who has the power to impose fiscal fines. They investigate all sudden and suspicious deaths in Scotland (similar to a coroner in legal systems derived from the English legal system), conduct fatal accident inquiries (a form of inquest unique to the Scottish legal system) and handle criminal complaints against the police (administrative complaints are handled by the Police Investigations and Review Commissioner).
A coroner is a government or judicial official who is empowered to conduct or order an inquest into the manner or cause of death, and to investigate or confirm the identity of an unknown person who has been found dead within the coroner's jurisdiction. In medieval times, English coroners were Crown officials who held financial powers and conducted some judicial investigations in order to counterbalance the power of sheriffs or bailiffs.
An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death; or the exam may be performed to evaluate any disease or injury that may be present for research or educational purposes. For animals, the term necropsy is generally reserved. Autopsies are usually performed by a specialized medical doctor called a pathologist.
A prosecutor is a legal representative of the prosecution in states with either the common law adversarial system or the civil law inquisitorial system. The prosecution is the legal party responsible for presenting the case in a criminal trial against the defendant, an individual accused of breaking the law. Typically, the prosecutor represents the state or the government in the case brought against the accused person. Prosecutors are typically lawyers who possess a law degree, and are recognised as suitable legal professionals by the court in which they are acting.
