Rule established

A "political offence" for purposes of extradition exemption requires that the act was incidental to and formed part of a political disturbance. Not every crime with a political motive qualifies; there must be a direct nexus between the crime and a genuine political uprising.

Facts

  • Armed group stormed the municipal palace in Bellinzona, Canton of Ticino
  • Castioni shot and killed a member of the State Council during the attack
  • Group aimed to overthrow the cantonal government
  • Switzerland requested extradition for murder

Issue

  1. What constitutes a "political offence" that bars extradition under the Extradition Act 1870?

Held

  • A political offence must be incidental to and form part of a political disturbance
  • The act must have a direct connection with the political objective
  • Castioni's act was committed during a genuine uprising against the government
  • Extradition refused

Ratio Decidendi

An offence is "political" for extradition purposes when it is incidental to and forms part of political disturbances. There must be a nexus between the criminal act and the political struggle. A purely private crime with political motivation does not qualify.

How to use it in an exam

  • Leading case defining "political offence exception" in extradition
  • Contrast with In re Meunier (anarchist bomb not political)
  • Key line: "In In re Castioni (1891), the court held that a political offence for extradition purposes must be incidental to and form part of a political disturbance, requiring a direct nexus between the act and the uprising."
