1. Introduction
Crimes of oppressive regimes, committed for ideological and political reasons, need to be investigated in a different manner than ordinary crimes. Very often, forensic evidence at crime scenes and bodies to examine do not exist. In these cases, evidence and investigative leads must be gained from an analysis of documents, political and military structures. This is a type of work that historians are trained to do, but lawyers and investigators are not.
In 1945, international prosecutions of war crimes started to deal with the crimes committed by the Axis powers during the Second World War. The victorious Allies established the International Military Tribunals in Nuremberg and Tokyo. In addition, countries which had been occupied by Nazi Germany prosecuted crimes committed on their territory in their military or domestic courts. Most of the investigation and prosecution units closed down in post-war years, with the exception of the Główna Komisja Badania Zbrodni Niemieckich w Polsce in Poland.Footnote 1 Crimes of the Nazi regime were also prosecuted before domestic courts in Germany, from 1945 on. Starting in 1958, investigations in the Federal Republic of Germany were centralized under the Central Agency for the Prosecution of Nazi crimes, in Ludwigsburg. The Central Agency remains open.
At the International Military Tribunal in Nuremberg (IMT), the traditional military prosecutor-led investigation model was used. According to a memoir, an attempt to make the linguistic and factual knowledge of German émigré academics available to US prosecutors, was met with fierce resistance.Footnote 2 The traditional model remained in use until the end of the IMT successor trials.
Following the IMT and successor trials, the issue of what role other professionals should play in the investigation and prosecution of Nazi war criminals before European national courts was defined by their legal systems. The continental systems used a prosecutor-led investigation model, in which historians had no place. For Nazi prosecutions in Germany, Alfred Streim, an experienced prosecutor, and Director of the Central Agency for the Prosecution of Nazi crimes in Ludwigsburg, identified the absence of historians on the investigation team as a major weakness. At the 30th anniversary of the Central Agency, he described the traditional German investigation structure of prosecutors and police, apart from support staff and translators, as not suitable for crimes which happened years ago, and observed that the prosecutor needs to understand the historical framework and find written evidence in archives or trial records, which only a historian can provide.Footnote 3
In the late 1970s, war crimes sections were established in several Western Allied countries following revelations that former Nazis, mainly non-German Nazi collaborators, had found refuge there. In 1979, the US government established The Office of Special Investigations (OSI) as its investigative unit.Footnote 4 In 1987 Canada and Australia followed with the Canadian War Crimes and Crimes Against Humanity Section (CAHWC) and the Special Investigations Unit (SIU), respectively. In 1991, the UK created both a general unit and a special unit in Scotland.Footnote 5
The use of interdisciplinary investigation teams by these units became a reality in the 1980s as a result of the leadership of OSI and the sharing of experiences with the newly formed units in Canada, Australia and the UK, and later with the International Criminal Tribunal for the Former Yugoslavia (ICTY). While the general structural investigation models in each country were not identical, in all of them historians became part of the prosecution teams. The shift to interdisciplinary investigation teams was facilitated by a common interest in successful prosecutions. Personal continuities, which existed between the national units and the ICTY, helped to promote the inclusion of country specialists into the structure of the Office of the Prosecutor.Footnote 6
The experiences of war crimes units in the 1980s confirmed that the further removed prosecutors and investigators are from a conflict – both in terms of space and time – the greater the need for country specialistsFootnote 7 to help them understand the countries under investigation: their languages, history, politics and societal norms. Lawyers, investigators and country specialists – and this is the major argument promoted in this article – working together in a manner which allows for information sharing, interaction, and open dialogue has led to superior investigations and prosecutions and will continue to do so.
Despite the successes of this interdisciplinary approach, the growing literature on the prosecution of crimes under international lawFootnote 8 rarely comments on its importance to creating efficient structures for an international prosecutor's office. One reason may be that the public interest is focused more on the outcome of trials than the structures behind the result. Another reason is the nature of available information. Evaluations of the work of international tribunals are largely based on open source material, like court judgments, witness testimony and court exhibits. Information on the inner workings of an investigation or the decision-making of a prosecutor is not in the public domain. Without access to these confidential documents, it is not possible to do an in-depth analysis of, for example, the choice of evidence in a given case and whether the investigation could have been, or was, improved through the contribution of country specialists. For this article, this methodological challenge was met through the input of professionals, who had experience as or with country specialists; who had, preferably, worked in more than one institution and had insight into periods of transition. The information was solicited via a questionnaireFootnote 9 and responses were given orally during interviews or by e-mail.
2. The interdisciplinary investigation model
OSI's interdisciplinary investigation model developed through a process of trial and error. Initially, OSI had a traditional prosecution office structure consisting of lawyers, investigators and support staff. Historians were hired only for specific research projects. For example, Dr. Peter Black (later OSI Chief Historian) was initially hired to do research in archives in New York. During the early 1980s, the usefulness of having historians on staff for professional document collection and historical analysis manifested itself.Footnote 10 Some investigators and attorneys opposed this change expressing concerns that historians were ill suited for investigations, and that they would want to do lengthy and useless research.Footnote 11 However, after several prosecutions stalled or failed due to lack of evidence and a growing realization by prosecutors and management that such complex cases could only be successfully tried if they rested on substantial and focused research and historical analysis, the decision to implement the new structure was taken.Footnote 12 In the 1980s, after they had received the necessary training, historians increasingly replaced investigators for most tasks.Footnote 13 By 2004, director Eli Rosenbaum had two deputies, one a lawyer, the second, the chief historian, who ensured that professional standards were maintained.Footnote 14
The OSI structure was the result of experience and pragmatism, not a pre-existing model. The later formed national units used the OSI model in developing their own structures.Footnote 15 All units had a lawyer as director and a sizeable component of lawyers and legal support staff. All had historians on staff, and according to the size of the unit, a chief historian. The role of investigators differed from country to country. While OSI had eliminated investigators altogether, SIU and the Scottish and British units had lawyers, investigators and historians under a director, who was a lawyer. The small size of unitsFootnote 16 and good interpersonal relations made these structures work.Footnote 17 In Canada investigators were not integrated into the Department of Justice (DOJ) section, but were in a separate Royal Canadian Mounted Police (RCMP) unit, as is traditional in Canada.Footnote 18 This division had serious negative repercussions, as RCMP investigators conducted investigations independently without legal or historical input or advice. This led to absurd situations, like police officers attempting to do research in historical archives in Europe. This structural problem was resolved in 1990 when the RCMP agreed to the Director of CAHWC having formal control over the investigations of Nazi war crimes.Footnote 19
2.1. A best practices model for interdisciplinary investigations
The best practices model for interdisciplinary investigations developed and used by OSI and the other national prosecutions offices is not fully recorded. The model applies equally to the investigation of Second World War and to contemporary international crimes.Footnote 20 As the next section will demonstrate, these hard-gained experiences can, but should not, be forgotten or ignored as international crimes are still being committed in various countries throughout the world. The model outlined below can provide the UN or other multinational bodies like the EU with the basic framework for interdisciplinary investigative units within a prosecutor's office.
2.1.1. Hiring
Country specialists were hired on the basis of factual knowledge and specific linguistic capacities. For Second World War cases, which concerned mainly Eastern Europe and a limited number of languages, it was possible to find academics with the required skills. For modern-era crimes – concerning conflicts which span the globe – this is more complicated, in particular for small units. Only the major conflicts (Rwanda, former Yugoslavia) and major languages could be covered with in-house country specialists. For cases concerning other parts of the world, the in-house country specialist has to work with a contractor,Footnote 21 also with academic training, preferably somebody residing in the country, where the bulk of the research has to be done.
Apart from their knowledge of languages, the country specialists had to have an academic degree (preferably a PhD), which guarantees that they can do research independently. This means, that they themselves identified, accessed and researched the sources required for their project, not only performed analysis on data put in front of them.Footnote 22 Strong analytical and writing skills were a prerequisite. These academics had to be trained to work as part of an investigation and litigation team.Footnote 23
2.1.2. First phase of an investigation
Every country specialist was assigned a caseload, matching her/his linguistic capabilities and scholarly specialization, and was placed in a team together with lawyers and investigators. The country specialist then had to locate, gather and analyze every piece of information relevant to her/his cases, in particular archival records, trial records of parallel trials or collections of victim statements.Footnote 24 The availability and accessibility of written records can differ between Nazi and modern cases, as well as organizations collecting and archiving information, such as NGOs or victim associations. The country specialist needs to know of existing documents, to think creatively about additional potential sources and to be persistent in obtaining the required access to them.Footnote 25
From the beginning of an investigation, it was critical that all information was put into a database in an organized manner, together with key words to facilitate searching. This requires qualified and linguistically competent staff. Serious problems with document management have arisen when investigation databases were not populated with the necessary foresight and care.
After the country specialist had analyzed and cross-referenced all information gathered, a background report, a suspect-specific report and a list of potential witnesses was provided for the lawyers and investigators on the team. It is particularly important that all previous statements (if any) of a potential witness have been obtained and evaluated. Only after this preliminary work had been done was a witness interviewed. This is to ensure that interviewers are as well informed as possible and that, hopefully, not more than one statement has to be obtained.
2.1.3. Next phase of investigation and trial
Up to this point most of the work involved evaluating written sources, which academics are trained to do. Next, investigators and/or lawyers started interviewing witnesses, with the help of the material provided. Country specialists assisted with witness interviews if the witness was a high profile figure or under exceptional circumstances. While the country specialists had done most of the work up to this point, now their role diminished and the work of the other team members increased. Throughout the course of the case, the country specialists were – apart from doing any research required – part of on-going discussions in the team and always available for consultation. (This has proven to be important in modern cases, where the media may provide a biased view on the conflict, which could influence the course of the investigation, if not rectified by the country specialist.Footnote 26 )
In addition, country specialists helped with document management and selection, and wrote the historical and background parts of reports, notices and indictments. They assisted with the identification and preparation of historical experts and were present in court, when testifying.
2.1.4. Framework
For this ‘best practices’ model to function effectively, the leadership of the organization needs to commit to it and support the head of the country specialist unit.Footnote 27 The head allocates work to country specialists, ensures that professional standards are maintained, research is confined to what is required for the cases, supports the country specialists’ role on the teams and monitors the progress of all cases.
3. Transition to ICTY and ICTR
Regrettably, the best practices example did not survive the shift to the international tribunals. This is surprising, because the personal continuity at the senior level of the ICTY was quite strong. In particular, Graham Blewitt, deputy prosecutor of the ICTY, who set up the tribunal in the beginning, had been director of SIU.Footnote 28 Other former SIU members came to hold important positions at ICTY, as well as the former head of the Scottish war crimes unit, Gavin Ruxton. The senior analyst, Dr. Patrick Treanor, a specialist on the Balkans, came from OSI. So, what happened?
Deputy Prosecutor Blewitt was well aware of the benefits of a multidisciplinary approach, and intended to draw on the experience gained at SIU when setting up the ICTY and to add historians/country specialists to the usual mix of lawyers and investigators. As the political and historical background of the conflict was important, he turned to historians like Treanor.Footnote 29 In his recollection, three different factors stood in the way: First, a lack of support from the UN, in particular the lack of support by the administration for obtaining the right level of positions and hiring. The senior analyst, for example, should have had a rank which allowed him to represent his group, but the UN created only a junior position.Footnote 30 Reasons for this are that nobody had any prior experience with international tribunals and the UN rules and regulations were not equipped for them.Footnote 31 Second, the conflict was still ongoing when the ICTY was established. That created a certain dynamic. While at SIU one had to recreate history, what happened in ex-Yugoslavia was in the daily news.Footnote 32 Police investigators were among the first to arrive at the tribunal, which shaped the structure of the tribunal in a certain way.Footnote 33 Third, international organizations have their own problems. The mix of an unprecedented structure and rapid growth and employees with different national, ethnic and cultural backgrounds, does not make for efficiency.Footnote 34
Treanor endorses Blewitt's assessment in respect of problems with hiring country specialists, as their profile did not fit into UN job descriptions.Footnote 35 He himself as ‘Research Officer’ (the only one in the UN) was only a P 4,Footnote 36 while such a senior position would normally require a P 5 classification.Footnote 37 It took till 1997/98 to improve the structure, even as management was sympathetic and shared Treanor's assessment that more and better analysis needed to be done. A Leadership Research Team (LRT, under Treanor himself) and a Military Analysis Team (MAT) were created, in part out of an earlier ‘Strategy Team’.Footnote 38 The restructuring allowed Treanor to implement the OSI model and to hire academics with graduate degrees, a solid knowledge of the history of Yugoslavia, the present conflict and the languages.Footnote 39 The group grew quickly from initially 12 members to more than 30 in 2004.Footnote 40 According to ICTY historian Dr. William Tomljanovich, by 1999 the US market for Balkan specialists was emptied.Footnote 41
In his choice of academics as analysts, Treanor was guided by his OSI experience. In general, the term ‘analyst’ (often subdivided into political, criminal and military analystsFootnote 42 ) can be undefined and at ICTY was often used interchangeably. Former MAT team leader Philip Coo points out that there needs to be an appreciation that within the term ‘analyst’, there can be substantial differences in roles and functions performed although all do analysis in some form. A distinction has to be made between analysts in LRT and MAT, who did specialized, in-depth research from which substantial written reports were generated, and those who were integrated directly into investigative teams and were used for more traditional crime analysis common to police forces operating in a domestic jurisdiction.Footnote 43
There were ongoing frictions between police investigators and historians/analysts, and also between investigators and lawyers. In part, this was connected to the more independent role police enjoy in common law systems, while in a civil law system police are instructed by prosecutors.Footnote 44 Frictions also were attributed to police trying to protect their turf, not share information, dominate analysts and use them for menial tasks.Footnote 45 This friction could have been reduced, if a Chief Analyst or Historian with a professional level equal to his police counterparts was at the management table to represent the interests of the analysts and country specialists.Footnote 46 Another long-lasting problem was the haphazard way investigators collected evidence and put it in the database. The ICTY document collection grew to almost eight million pages, but the careless and unprofessional way documents were registered in the beginning made it difficult to locate evidence in a timely manner and caused disclosure issues.Footnote 47 Overtime, the evidence-collecting role of investigators was reduced. After the opening of archives in the former Yugoslavia in the early 2000s, historians who spoke Serbo-Croatian and knew the conflict and the historical background were required to research the archival holdings and identify documents which were crucial for litigation.Footnote 48
In 2000/2001 Prosecutor Carla Del Ponte implemented a major change by putting Senior Trial Attorneys in charge of case development. According to her memoirs, this was triggered by complaints by senior lawyers that the evidence collected by investigators was not sufficient for litigation.Footnote 49 These developments were strikingly similar to those experienced by OSI in the 1980s. The requirements of the prosecution, the need to understand political and military command structures and to put documents and witness statements into the larger political and historical background, up-graded historians and created a new distribution of work among lawyers, investigators and country specialists. Necessities shaped structures.
Unfortunately, the personal continuity which existed between the national Second World War war crimes units and ICTY did not extend to the International Criminal Tribunal for Rwanda (ICTR). Blewitt was deputy prosecutor only for the ICTY (while both tribunals had the same prosecutor till 2003). Conditions at the ICTR were bad; in particular, in the beginning it was difficult to recruit qualified people.Footnote 50
Practical necessities again led to the same type of structural changes as described above for the ICTY. In 2000, Laurent Walpen was appointed as new Chief of Investigations in Kigali.Footnote 51 There had been a long gap between him and his predecessor, causing a lot of problems and requiring major restructuring. How major this was is reflected in a strategy paper in which the very basic components of an investigation are described.Footnote 52 As one part of his effort, Walpen restructured investigation teams and strengthened the analytical capacity. Analysts should be part of every investigation team. In addition, a central analysis unit was created.Footnote 53
At the ICTR, Walpen only knew of a criminal analyst, with a recognized career path through which one was trained as an analyst.Footnote 54 These comparative new-comers to police organizationsFootnote 55 were hard to find.Footnote 56 At the ICTR, nobody had been aware of analysts before 1996.Footnote 57 The type of country specialist successfully introduced by Treanor at ICTY was unknown.Footnote 58 Thus, the term ‘analyst’ on an ICTR job advertisement did not necessarily lead to the person most suitable for the job.Footnote 59
A recent publication focusing on the question of whether international courts correctly depicted historical events reinforces the above. Richard Wilson did an in-depth assessment of the ICTY and found, in particular, the two leadership teams to be an improvement, because they ‘enhanced the ability of the prosecutors to integrate historical and contextual evidence into their cases’.Footnote 60 In his view, the ICTY wrote an authoritative account of the conflict in Bosnia, and the systematic persecution of Bosnian Muslims.Footnote 61 On other tribunals he is less complimentary: ‘Lacking a critical mass of social and historical researchers in the OTP, the ICTR's analysis had a thinner and brittle quality than that at the ICTY.’Footnote 62 Wilson concludes: ‘For some inexplicable reason, the positive experience of the Leadership Research Team (LRT) and the Military Analysis Team in the Office of the Prosecutor at the ICTY has not been reproduced in subsequent international criminal trials.’Footnote 63
4. The ECCC and SCSL – Two very different experiences
While this article discusses the experiences of various prosecution bodies in investigating and prosecuting international crimes, it cannot deal with all international tribunals.Footnote 64 Suffice it to say, finding the right balance between lawyers, investigators and country specialists continues to be work in progress. The International Criminal Court (ICC), for example, is trying new approaches.Footnote 65 Regrettably, information about the successes and failures of the ICC structures was not available to the author in necessary detail at the time of research for this article. Hopefully, individuals with a direct insight into the contributions of country specialists to the ICC will publish on this subject in the future.
Two other tribunals – the Extraordinary Chambers in the Courts of Cambodia (ECCC) and the Special Court for Sierra Leone (SCSL) – will be briefly commented upon, because they represent diametrically opposed approaches to the use of country specialists. This allows a comparison of their usefulness for the success of a prosecution.
In the case of Cambodia, historical research on the Khmer Rouge, including collecting documents and interviewing witnesses had been undertaken by scholars and documentation centers long before the ECCC was finally set up, after many political problems.Footnote 66 How did the fact that country specialists were already available when the tribunal was created impact on its structure?
As in previous examples, at its inception the tribunal was given only an inadequate skeleton staff, made up of a few lawyers, without any researchers, analysts or investigators.Footnote 67 This first staffing table was prepared by the UN Office of the Legal Affairs (OLA).Footnote 68 Reasons for omitting to include key components of a prosecutor's office were inexperience on the side of the UN,Footnote 69 donor fatigueFootnote 70 and the (unfounded) hope that the work done by the Documentation Center of Cambodia would make further investigations unnecessary.Footnote 71
Robert Petit, the first International Co-Prosecutor (OCP), who had had extensive experience with other international courts and had worked at CAHWC, made his acceptance of the job dependent on adequate staffing, in particular with researchers, analysts and investigators.Footnote 72 Both he and the International Co-Investigating Judge (OCIJ) hired Khmer Rouge specialists, among them Dr. Stephen HederFootnote 73 (at OCIJ) and Dr. Craig EtchesonFootnote 74 (at OCP). These two were able to recommend other suitable candidates.Footnote 75
The experiences of these two Khmer Rouge specialists are instructive. The workload was overwhelming, which resulted in everybody having to participate according to their capability, not their function, and work in very close co-operation.Footnote 76 The country specialists combined field interviews, document research and analysis, provided feedback in witness interviews, and reviewed and commented on the work product of the lawyers.Footnote 77 When more and more interdisciplinary staff was added (anthropologists, people from international organizations) frictions started with police investigators, who also brought in the type of analysts they were used to working with.Footnote 78
Nevertheless, the assessment of both country specialists is positive. Heder was satisfied with the way his prior published and unpublished writings and his work for the court contributed to build and litigate cases.Footnote 79 According to Etcheson, ‘From my perspective, the interdisciplinary nature of the OCP team contributed significantly to the efficiency of our work and to the quality of our work product’.Footnote 80 This positive view is supported by an otherwise quite critical outside assessment. The authors are of the opinion that ECCC greatly benefitted from the contribution of country specialists, because of their knowledge of Khmer Rouge history and their efforts at collecting information beforehand.Footnote 81 The limited number of prosecutions is not the result of structural deficiencies, but of political circumstances.Footnote 82
The SCSL can be considered a counter-example. The prosecution did not hire any country specialists, but relied on the traditional mix of investigators and lawyers.Footnote 83 Insight into the reasons for this is found in a report on the ‘Investigative practices of the Office of the Prosecutor’.Footnote 84 According to the first Chief of Investigation, Alan White, it was decided, after visiting ICTY and ICTR, that the model of investigators working according to the instructions of lawyers was not efficient and the Chief of Investigations would need independence in order to fulfil his responsibilities.Footnote 85 Behind this decision stood the philosophy that SCSL was to be a new model for international tribunals, with lower costs and a more effective completion strategy.Footnote 86
David Crane, the first prosecutor, hired only one human rights researcher, Corinne Dufka, for advice on the history of the conflict.Footnote 87 Dufka provided briefing materials, including an atrocity-mapping project with the geographic and temporal distribution of various incidents, but found to her dismay that the investigators showed very little interest in these materials. ‘I gave them orientation packets which they didn't read and then they would go out and do investigations, and they were ill equipped to be doing proper criminal investigations, because they hadn't done their homework’.Footnote 88 This impeded the investigation, for instance the ability to develop leads (‘If you don't know what you are trying to investigate, you can't find good leads’).Footnote 89 The lack of knowledge on how to effectively obtain information from Sierra Leoneans led to many flawed statements as well.Footnote 90
This criticism was echoed by outside observers, mainly social anthropologists – academics, who were specialized on Sierra Leone and had spent years doing research there, with a focus on interviewing people.Footnote 91 A focal point for critics was the first SLSC trial against the Civil Defense Forces (CDF). On the CDF issue, the prosecution called a British military expertFootnote 92 and the defence called social anthropologist Danny Hoffman, who had written his PhD on the Kamajors, a social movement on which the CDF was based. Hoffman massively disagreed with the way the prosecution characterized the CDF.Footnote 93 The characterization of the CDF was central to the legal question of ‘command responsibility’. Hoffman argued against a command structure, speaking instead of a ‘militarized social movement’.Footnote 94 Whether Sierra Leonean or Western norms were applied also effected the legal classification of child soldiers and forced marriages.Footnote 95 Criticism ranges from the allegation that the SCSL did not take ‘anthropological evidence into consideration’,Footnote 96 to the charge of ‘legal imperialism’.Footnote 97 Nancy Amoury Combs’ research on ICTR, East Timor and SCSL trial records and judgments led her to the conclusion that testimonial deficiencies – caused by a lack of understanding the conflict or cultural facts – are so strong that international justice amounts to show trials.Footnote 98
This article does not offer an opinion on whether this criticism is justified, but in the context of our argument it proposes that a situation like that should never have occurred. The prosecution should have identified and consulted the leading scholars in the field prior to an indictment and they should have had social anthropologists among the country specialists on staff.
5. Conclusion and recommendation
The evidence to support the inclusion of academically trained country specialists – historians, political scientists, social anthropologists or others – into the structure the prosecutor's office for the investigation and prosecution of crimes under international law is clear and compelling. A recent publication on best practices for international tribunals, based on the experiences of people who had worked at the offices of international prosecutors, provides support to the structural model advocated in this article.Footnote 99 Their recommendations are based on the difficulties they encountered. One segment of the book reads like a compendium of bad police practices, recommending that investigators write ‘meaningful’ reports, analyze witness statements (and not just put the date when they were recorded on them), and prepare thoroughly before interviews.Footnote 100 Another set of recommendations advocates a balance of investigative, legal and analytical capacity, each group being placed under professional management and working in close collaboration.Footnote 101 The need to avoid chaos in the evidence unit is also stressed.Footnote 102 These problems are very similar to those described above, and can be remedied using the recommended best practices model.
Time and again, new tribunals are set up, normally under somewhat chaotic conditions, when speedy action is required. When the UN conducts the political negotiations for new tribunals, they do not provide more than a basic structural outline and leave the implementation to the persons appointed to lead the organization. This inevitably leads to a new round of trial and error. To avoid the useless repetition of mistakes of the past in the future, a structure of the prosecutor's office including country specialists using the best practices model should be discussed, agreed upon and made an international norm. The best functioning wheel has been designed, tried and tested: We should stop reinventing it.
