Re: DNT: Agenda for April 10 call

I agree (and have previously argued) that there is a strong argument 
that the level of prescriptiveness for consent should be *greater* for a 
party seeking an exception to a stated preference expression than for 
the setting of that preference in the first place.  But in the 
Washington meeting, I thought the sense of the room was that the two 
should at least be equivalent.  Perhaps this is reflected in the 
minutes; I have also written approximately 100 emails on the topic, 
mostly in the first half of last year, which I do not have the capacity 
to pore through at the moment --- there may be details in there from my 
discussions with Roy, Shane, and others.
