Using Sharia law to settle disputes can be innocent, but it can also undermine Western ideas of fairness. Journalist Joachim Wagner, author of a new book on parallel justice, discusses the influence of Islamic arbitrators on Germany's legal system.
SPIEGEL: Mr. Wagner, you spent nine months researching the Islamic shadow justice system. What kind of a world is it?
Wagner: Very foreign, and for a German lawyer, completely incomprehensible at first. It follows its own rules. The Islamic arbitrators aren't interested in evidence when they deliver a judgment, and unlike in German criminal law, the question of who is at fault doesn't play much of a role.
