GENEVA, Oct 30 (Reuters) – The top Swiss court on Friday confirmed a guilty ​verdict against a Liberian warlord, ‌upholding his 20 year sentence in the country’s first ever war crimes trial.

Alieu Kosiah, who fought in the 1990s ‌against ​then-president Charles Taylor’s ⁠army during Liberia’s ⁠brutal civil war, was originally sentenced to 20 years in prison in June 2021 for rape, murder ​and cannibalism.

An earlier appeal was rejected in 2023 by the ⁠Federal Criminal Court and ⁠the dismissal of his ​second appeal by Switzerland’s highest tribunal ​the Federal Supreme Court published on ‌Friday closes the case.

“This is a landmark decision, made possible by the courage of these victims, ⁠who have written a page of legal history,” said Alain Werner, Director of Civitas ⁠Maxima, ‌an NGO representing victims ⁠in this case.

However, the ​court ‌reversed a parallel conviction for ​crimes against ⁠humanity on the grounds that the law on this crime introduced in 2011 cannot be applied retroactively.
