The 1998 arrest of Senator Augusto Pinochet in London, on the orders of a Spanish judge seeking his extradition for human rights crimes, made headlines all over the world. Part of a wider, ongoing attempt by human rights activists and lawyers to prosecute the crimes of Latin American military regimes, the case has important implications for national and international law and for politics, diplomacy and democracy. This book brings together political scientists and lawyers from Latin America, the United States, Spain and the UK to analyse the political and historical context of the case, its progress through the courts in the UK and Chile, its handling by national governments, and its political and legal implications, both national and international.
