This book by key actors in and behind the Australian Special Investigations Unit (1987–94) discusses its mandate and work to investigate suspected World War II war criminals who had come from Eastern Europe to Australia. In 1947 alone, Australia welcomed more than 170,000 displaced persons, some of whom had assisted the Nazis in mass-killings (‘both communist and Western intelligence services recruited Nazi war criminals for their operations during the Cold War’). The book describes how the Unit’s 80 staff, among their activities, interviewed witnesses and exhumed mass-graves of Jewish victims in the former Soviet Union in 1989–91, investigating more than 800 cases, and referring four of them to the Commonwealth Director of Public Prosecutions for prosecution. The proceedings encountered challenges of ‘old evidence’ as it has become known in the literature. Authors discuss ‘cases that got away’ regarding Latvia (Chapter 6), Croatia (7) and Lithuania (8). In Chapters 10–13, the main lawyers involved discuss their cases, including Graham T Blewitt who went on to become Deputy Prosecutor of the International Criminal Tribunal for the Former Yugoslavia (ICTY). When constructing its Office of the Prosecutor, he brought fellow Australians Grant Niemann, John Ralston and Bob Reid (all contributors to the book) into vital prosecutorial and investigatory positions at the ICTY. Together they have reason to be proud of what they achieved through the work of the Special Investigations Unit and the ICTY. But the United Nations rightly criticized Blewitt for hiring so many Australians, as an international prosecution service should never be seen to be dominated by one group.
