As mentioned earlier, if a crime is committed in country A whilst residing in country B,extradition law states that he/she be extradited back to country A in order to be tried.
Complications arise however when the requesting state may seem to have improper motives.
For example, a person being extradited on the basis of a political offence may in fact be hiding, or disguising, a different persecution, say for religious beliefs.
For this reason, extradition solicitors are provided to support and guide their client, ensuring their interests are always protected.
