After his capture in 1999, Öcalan called for a halt in PKK attacks, and again advocated for a peaceful solution for the Kurdish conflict inside the borders of Turkey. Öcalan called for the foundation of a "Truth and Justice Commission" by Kurdish institutions in order to investigate war crimes committed by both the PKK and Turkish security forces. A similar structure began functioning in May 2006. In March 2005, Öcalan issued the "Declaration of Democratic confederalism in Kurdistan" calling for a border-free confederation between the Kurdish regions of Southeastern Turkey (called "Northern Kurdistan" by Kurds), Northeast Syria ("Western Kurdistan"), Northern Iraq ("South Kurdistan"), and Northwestern Iran ("East Kurdistan"). In this zone, three bodies of law would be implemented: EU law, Turkish/Syrian/Iraqi/Iranian law and Kurdish law. This proposal was adopted by the PKK programme following the "Refoundation Congress" in April 2005.
