Currently, three individuals are officially recognised as victims in the proceedings. They are Abu Zubaydah, Abd al-Rahim al-Nashiri and Walid bin Attash, all detained in the Guantanamo base. They claim to have been illegally imprisoned and tortured in Poland. The investigation into the operations of a secret CIA facility said to have been established in Poland as part of the so-called war on terror, was launched in 2008.

The cases of al-Nashiri and Abu Zubaydah vs. Poland are pending before the European Court of Human Rights. On 2 and 3 December 2013, the Court heard the joined cases.

In January 2014 The Washington Post wrote that in 2003 Poland reportedly received 15 million dollars from US authorities to host the secret prison in Stare Kiejkuty.
