Quick Summary

Switzerland’s supreme court upheld a 20-year jail sentence for former Liberian rebel commander Alieu Kosiah on Friday but overturned his conviction for crimes against humanity. The original 2021 verdict by Switzerland’s Federal Criminal Court found Kosiah, aged 51 at the time, guilty of war crimes committed between 1993 and 1995 during Liberia's civil wars, in which around 250,000 people died. The supreme court upheld his sentence but acquitted him on charges of crimes against humanity due to Swiss law’s principle of non-retroactivity for laws established after the crimes were committed.

Story summary

On October 30, 2026, Switzerland's Federal Supreme Court upheld Alieu Kosiah's 20-year prison sentence for war crimes committed in Liberia during the early 1990s. Originally convicted by the Swiss Federal Criminal Court in June 2021, Kosiah was found guilty of rape, murder, and cannibalism against civilians during Liberia's civil war. The court also dismissed his second appeal, which had been rejected previously in 2023, thus finalizing the conviction as Switzerland’s first-ever war crimes trial by a civilian court. However, the verdict reversed an earlier finding for crimes against humanity due to legal restrictions on retroactive application of such laws introduced after the crimes were committed. The case was spearheaded by Civitas Maxima, an NGO working to prosecute international war criminals.
