Guam guy:
Both MECs have posted info about this. But in a nut shell after agreeing to a mid-June timeline (they all assumed mid-June this year

) the negotiating group working on R&I was making progress and then after a break the UCH boys came back and annulled all the progress and returned to their Oct 2010 position.
Essentially the UCH team withdrew their position after agreements had been made at the table and combine this with the time table of mid-June they are negotiating in bad faith in the mediated talks.
