Allthough Samardzic's "partition plan" has been discussed in all newspapers I haven't seen yet a complete list of what Samardzic proposes and contradicting reports keep appearing. He claims that the plan covers all Serb enclaves. It seems he felt pressured to come with the plan now because of the Eulex and other time limits surrounding Kosovo's independence declaration might bring the enclaves under direct rule from Pristina within a few months.
As Tim Judah comments, the Ahtisaari plan already provides for a considerable separation. The plan extends this to include police and judiciary - among others. I find this a useful extension. I always felt that the Ahtisaari plan was too limited for the high tension and high discrimination environment of Kosovo.
Some elements seem strange to me. For example the claim that only Serbs would serve as judges. How do they want to explain that to the Albanian villages in the north? I cannot imagine that the UN will accept such a proposal. But maybe there is something in the not published parts of the plan that deals with the rights of the Albanians.
The UN has said to study the plan and - allthough they see many unacceptable elements - seem to accept it as a basis for negotiations.
