[JURIST] Polish prosecutors announced Wednesday that they will open an investigation into the alleged mistreatment of accused USS Cole [JURIST news archive] bomber Abd al-Rahim al-Nashiri [NYT profile] at a secret CIA prison [JURIST news archive] in Poland. The investigation is in response to the request [JURIST report] filed Tuesday by human rights group Open Society Justice Initiative (OSJI) [advocacy website] and al-Nashiri’s lawyers. The request asks prosecutors to scrutinize al-Nashiri’s detention and treatment in their investigation [JURIST report] into the allegations of a CIA-operated secret prison in the country and to prosecute those responsible for the acts on Polish soil. Earlier this month, an ex-CIA agent confirmed [Spiegel report] that the agency tortured al-Nashiri in 2002 at a secret prison in Poland. OSJI stated that the filing represents the first attempt [press release] by an extraordinary rendition [JURIST news archive] victim to pursue a legal remedy within the Polish court system. Al-Nashiri remains a detainee at Guantanamo Bay [JURIST news archive], despite an announcement last month by the Obama administration that charges against him are not pending [JURIST report] or being considered. The Pentagon formally dropped charges [JURIST report] against al-Nashiri in February 2009, effectively ending his prosecution under the Military Commissions Act of 2006 [text, PDF].

The commencement of the investigation comes one week after former Polish prime minister Leszek Miller denied any knowledge [JURIST report] of a secret CIA prison in Poland and indicated that he will not discuss allegations of torture until the Polish government’s investigation is complete. Allegations against Poland came in a June 2007 report [text; JURIST report] to the Council of Europe [official website] by Swiss Senator Dick Marty. The report concluded that numerous European governments had cooperated with the CIA program. In February 2007, the European Parliament condemned more than a dozen European states [JURIST report] for their roles in the program. Several nations have been accused of obstructing European probes into the secret prison allegations, including Poland [JURIST report], which allegedly housed the largest CIA detention facility in Europe [JURIST report].
