Lawyers for Guantánamo Bay detainee Abu Zubaydah on Jan. 28 asked the European Court of Human Rights (ECHR) to rule on whether Poland violated their client's rights by aiding the US in detaining and allegedly torturing Zubaydah in a secret CIA prison. Zubaydah, a top al-Qaeda suspect, alleges that he was transferred to Poland and subjected to "enhanced interrogation techniques." An investigation into the prison has been ongoing in Poland since 2008, but Zubaydah's lawyers argued that it has made no noticeable effort to bring any perpetrators to justice. The letter is notice that an application for a hearing will be filed.
