[JURIST] The UN Working Group on Arbitrary Detention [official website] Thursday condemned the 2001 Miami federal court conviction of five Cubans who spied on US anti-Castro groups ["Free the Five" advocacy website], calling their long jail terms – including three life sentences – "arbitrary." In an opinion obtained by Reuters on Thursday, the independent five-person panel of lawyers said that the trial lacked "objectivity and impartiality," and also noted that the five had been held in solitary confinement for 17 months prior to trial. The UN group, whose rulings are not binding on countries, urged the US government "to adopt the necessary steps to remedy the situation." Reuters has more.
