"Unless amendments X, Y, and Z are passed, you must vote No".
Does FFII know what X, Y, and Z are?
So far the amendments that have been put to vote are not known yet.
One simple rule is: if Rocard, Greens and EDD don't all recommend "yes", better vote "no". If one or more of the Rocard group's amendments are rejected, vote "no".
This isn't to say that the directive with the Rocard group's amendments will be an acceptable one. Unless about 90% of the recitals and articles are deleted or rewritten along the lines of the FFII counter-proposals, it will still be a bad law that ought to be rejected, if the EP has any self-esteem.
