Standardization of Evidence Retrieval from of Mass Grave Sites by Douglas Brady

I. Introduction

Whether discovered in the aftermath of a regime change or when a party takes control over territory during a conflict, mass graves are the culmination of immeasurable harm and human suffering, indicating possible war crimes or crimes against humanity.[1] In 2018, after the Islamic State was driven out of its de facto capital city of Raqqa, Syrian workers found at least nine mass graves in and around the city.[2] As recently as July 2021, the Governor of Turkey’s bordering province announced that officials discovered a mass grave in the nearby Syrian province of Afrin, alleging that YPG Kurdish forces were responsible—although Agence France-Presse, who broke the story, was unable to verify the claims.[3]

The preservation of documentary evidence from mass graves allows for its use during criminal prosecution and brings closure to victims’ families and communities.[4] Currently, there is not a uniform international standard for protecting and investigating mass graves.[5] Although witness testimony is important for the International Criminal Court’s (“ICC”) criminal prosecution stemming from mass graves, documentary evidence can corroborate witness testimony and provide further independent proof of wrongdoing.[6] Additionally, preserving evidence from mass graves helps to identify victims and to provide answers to families.

II. Rome Statute and the Bournemouth Protocol

In July 2002, the Rome Statute established the ICC, which has jurisdiction over the crime of genocide, crimes against humanity, and war crimes.[7] The ICC has jurisdiction only over states which are a Party to the Statute and provides for the prosecution of individual persons who commit, order, aid, or otherwise contribute to the commission of these crimes—regardless of their official capacity.[8] In trials, the ICC presumes innocence, and the burden of proof rests with the prosecutor who must establish guilt beyond a reasonable doubt to convict.[9]

In regard to documentary evidence collected by a State, the ICC will not apply the State’s national law, but will instead follow the Rome Statute and the ICC’s Rules of Procedure and Evidence.[10] Under these Rules, the Pre-Trial Chamber has to authorize the prosecutor to investigate and may take such measures as may be necessary to ensure the efficiency and integrity of the proceedings regarding, among other things, examining, collecting, or testing evidence, “which may not be available subsequently for the purposes of a trial.”[11] However, documenting and ensuring the integrity of mass grave evidence may need to occur before an ICC investigation—ideally upon any mass grave’s discovery.

Recently, Melanie Kinkner and Ellie Smith, professors at Bournemouth University specializing in international law and human rights, created the Bournemouth Protocol on Mass Grave Protection and Investigation (“Protocol”)as a set of common standards and a chronology for the entire process across various disciplines.[12] The Protocol defines mass grave (previously undefined in international law) and provides the international legal basis for their proposals.[13] The authors acknowledge that mass graves are context-specific and accompany many challenges because “mass graves typically occur within highly-charged political and/or cultural context, which may still be ongoing at the time of investigation.”[14] Nevertheless, the Protocol highlights the value of uniform standards for mass grave investigation to create evidential links to perpetrators. The Protocol also warns that judicial investigation and prosecution should not take priority over the totality of mass grave investigation and protection efforts.[15]

III. International, Impartial and Independent Mechanism (“IIIM”) in Syria

In late 2016, the United Nations General Assembly established the first International, Impartial, and Independent Mechanism (“Syrian Mechanism”) to facilitate and expedite in the investigation and prosecution of genocide, crimes against humanity, and war crimes in the Syrian Civil War by collecting, consolidating, preserving and analyzing evidence.[16] However, the Syrian Mechanism complements local NGOs and the Independent International Commission of Inquiry on the Syrian Arab Republic, all of whom are primary sources of evidence gathering.[17] The Syrian regime does not allow the Syrian Mechanism to enter the country.[18] Thus, the Mechanism instead focuses primarily on digital documentation.[19] Short of doing the prosecuting itself, the Syrian Mechanism carries a prosecutorial standard for evidence gathering to service future tribunals.[20]

Ultimately, the evidence collected by an IIIM needs to be admissible in various courts for this new mechanism to prove effective.[21] For example, in the ad hoc International Criminal Tribunals for the former Yugoslavia and Rwanda, prosecutors introduced documentary evidence that helped lead to various convictions.[22] As of this writing, the Syrian Mechanism is still finalizing its Internal Procedures and Methods of Work, highlighting the need for universal standards for evidence collection, especially in event that mass graves are uncovered.[23] The Syrian Mechanism’s most recent report to the U.N. addressed the challenges brought on by the COVID-19 pandemic: “[b]ecause of the sensitivity of the matters at issue and the legitimate security concerns of many sources, not being to conduct in-person meetings and converse directly has had an impact on the pace of the Mechanism’s new engagements and cooperation discussion.”[24]

IV. Conclusion

The uniform use of the above-mentioned mechanisms could standardize the documentation of incidents, including atrocities such as mass graves, to push for accountability during the conflict instead of after a peace agreement.[25] In 2018, the U.N. Human Rights Council established the Independent Investigative Mechanism in Myanmar with a mandate much like that of the Syrian Mechanism.[26] This suggests that comparable mechanisms will be implemented during other current and future conflicts.

Still, challenges concerning evidence collection and protection of mass graves remain. Because these mechanisms often have limited access to the countries experiencing conflict and local resources may have limited capacity and resources, a uniform standard regarding mass graves could maximize the utility of these efforts to achieve future accountability and justice in the ICC or other courts.
