Guantánamo Bay detainees were granted the right to file habeas corpus petitions – to challenge the lawfulness of their detention – in 2004. The US Supreme Court finally recognized the existence of this as a constitutional right on 2008. On 6 August 2008, Abu Zubaydah’s lawyers filed a habeas corpus petition in the US District Court for the District of Columbia, challenging the lawfulness of his detention. Since then, there have been many filings, but as yet no decision.
