A long time ago, when I worked for IBM in Indianapolis, whoever was in the office at lunch time would go out together. We had a rule about selecting a place to eat - after one place was suggested, no one was allowed to veto that location without offering an alternative. I believe that the CRB would be a lot more effective if they were to suggest an alternative to the process or at least tell the ITAC what they don't like about it, instead of just saying 'NO'.
I guess that comes under the general heading of 'communication', yes?
