Swiss Supreme Court: Alieu Kosiah Verdict Upholds 20-Year War Crimes Sentence

• The Swiss Federal Supreme Court upheld former ULIMO commander Alieu Kosiah's 20-year sentence for war crimes committed in Liberia's Lofa County.
• Kosiah was acquitted of crimes against humanity, as the relevant Swiss law, enacted in 2011, could not be applied retroactively to acts from 1993-1995.
• This verdict represents the first war crimes conviction by a Swiss civilian court and the first conviction of a Liberian for civil war atrocities anywhere.
• The ruling intensifies focus on Liberia's continued failure to establish a domestic War and Economic Crimes Court, despite past commitments.

The Supreme Court's decision to acquit Kosiah of crimes against humanity hinged on the principle of non-retroactivity.

Switzerland's Federal Supreme Court recently affirmed the 20-year prison sentence for Alieu Kosiah, a former commander of the United Liberation Movement of Liberia for Democracy (ULIMO), for war crimes committed in Liberia's Lofa County. This decision, made public on a Friday, solidifies the first war crimes conviction ever issued by a Swiss civilian court and marks the initial conviction globally of a Liberian for atrocities during the nation's civil wars, which spanned from 1989 to 2003 and resulted in approximately 250,000 fatalities.

While the court upheld the war crimes conviction, it acquitted Kosiah of charges related to crimes against humanity. This partial acquittal, however, does not alter his 20-year sentence or his eventual expulsion from Switzerland upon release. The specific offenses for which Kosiah was found guilty, committed between 1993 and 1995, included the killing of civilians, ordering their deaths, rape, deploying a child soldier, commanding pillage, cruel treatment of non-combatants, and the desecration of a deceased civilian's body through an act of cannibalism. The Appeals Chamber of Switzerland's Federal Criminal Court had previously determined that these crimes alone warranted a 150-year sentence, which was subsequently reduced to 20 years, the maximum penalty allowed under Swiss law.

The Supreme Court's decision to acquit Kosiah of crimes against humanity hinged on the principle of non-retroactivity. The provision for crimes against humanity was integrated into Swiss law in 2011, meaning it could not be applied to acts committed by Kosiah between 1993 and 1995, which predated the law's enactment. This clarification on the application of Swiss international criminal law is critical for understanding jurisdiction and applicable law in international atrocity cases.

This ruling establishes a significant precedent within Swiss jurisprudence, being the first war crimes conviction by a civilian court in the country. It also highlights the complexities of prosecuting historical international crimes under evolving legal frameworks, particularly concerning the non-retroactivity principle for newly introduced legal provisions. Despite the acquittal on one charge, the upheld 20-year sentence underscores the gravity with which the Swiss legal system views the war crimes committed.

The journey to this verdict has been protracted, spanning over three decades since the atrocities occurred and twelve years since Kosiah's arrest in November 2014. Kosiah, who had settled in Switzerland in the late 1990s, was apprehended following a criminal complaint filed by Liberian victims. Throughout the investigative process and both trials, survivors made the arduous journey from Liberia to provide crucial testimony, playing a pivotal role in the case.

Organizations such as Civitas Maxima, a Geneva-based group representing the victims, and the Liberian Global Justice and Research Project (GJRP), which has meticulously documented civil war crimes for over a decade, were instrumental in constructing the prosecution's case. Alain Werner, Director of Civitas Maxima, welcomed the finality of the conviction but expressed profound disappointment regarding the acquittal on crimes against humanity. Werner contended that the systematic targeting of civilians in Lofa—through killings, rapes, looting, and forced labor—unequivocally met the definition of crimes against humanity, reflecting the victims' perspective on the widespread and systematic nature of the attacks.

The Swiss Federal Supreme Court ruling casts a renewed spotlight on Liberia's persistent inability to prosecute its own war criminals domestically. More than two decades after the cessation of the civil wars, which involved the recruitment of over 21,000 child soldiers, no war crimes trials have been conducted on Liberian soil. Despite previous commitments to establish a War and Economic Crimes Court, this institution remains non-operational and has yet to hear a single case.

Hassan Bility, Director of GJRP, acknowledged the decade-long commitment of Swiss authorities that facilitated Liberian survivors' direct participation in the legal proceedings. However, Bility strongly emphasized the critical necessity for justice to be administered within Liberia, asserting that victims should not be compelled to seek redress in European or American courts. This ongoing international pressure for Liberia to establish its own War and Economic Crimes Court indicates a persistent risk of extraterritorial prosecution for individuals involved in past conflicts, reinforcing the call for domestic accountability.

This ruling clarifies the application of Swiss international criminal law, particularly the non-retroactivity principle for crimes against humanity provisions, which is critical for lawyers advising on jurisdiction and applicable law in international atrocity cases. It also underscores the continued international pressure for Liberia to establish its own War and Economic Crimes Court, indicating a persistent risk of extraterritorial prosecution for individuals involved in past conflicts.
