Switzerland’s Federal Criminal Court is set to decide Tuesday whether it can judge crimes against humanity allegedly committed before 2011, in the trial of a former Gambian minister.Ousman Sonko is accused of various crimes against humanity allegedly committed between 2000 and 2016 under the regime of former Gambian dictator Yahya Jammeh.The trial is taking place under the principle of universal jurisdiction, which allows countries to prosecute alleged crimes against humanity, war crimes and genocide regardless of where they were committed.In 2011, Switzerland enshrined into law the right to judge such serious crimes alleged to have taken place abroad — provided that the suspect is on Swiss soil.Sonko, who turned 55 on Tuesday, has been in custody since his arrest in Switzerland in January 2017, after applying for asylum following his sacking as interior minister.The Federal Criminal Court is due to take a position on whether it can try crimes against humanity that allegedly took place before 2011, when the law came into force.Sonko’s lawyer Philippe Currat argued Monday that under the principle of non-retroactivity, his client should not be tried for any alleged acts before this date.He furthermore requested the entire case be dismissed, claiming there had been violations of the fundamental rules of procedure, and sought around 800,000 Swiss francs ($945,000) in reparations for his client.- Rape, torture charges -Jammeh ruled The Gambia with an iron grip from 1994 to 2016.
