First fire George Lucas from having any decision over the EU since the eu is not G canon and George dictating to the eu therefore is pointless.
Having overall guidelines is one thing, not violating the canon of the oot etc, but then Lucas himself rewrote the universe from scratch starting in 1994 and tried to re-edit the older movies to fit his new vision.
With the Clone wars cartoon he has basically destroyed any sense of continuity in the EU or the film universe. Since he just makes crap up as he goes.
