Most CABE and chapter events are administered under the Chatham House Rule. There is only one rule.
"WHEN A MEETING, OR PART THEREOF, IS HELD UNDER THE CHATHAM HOUSE RULE, PARTICIPANTS ARE FREE TO USE THE INFORMATION RECEIVED, BUT NEITHER THE IDENTITY NOR THE AFFILIATION OF THE SPEAKER(S), NOR THAT OF ANY OTHER PARTICIPANT, MAY BE REVEALED".
Founded in 1920, Chatham House, officially known as The Royal Institute of International Affairs, is based in the heart of London. As a measure of its importance in the world of international relations, the name 'Chatham House' - the building - is now commonly used to refer to the organization.
The wikipedia discussion of the Chatham House Rule is instructive and is quoted below (retrieved 14/09/06)
- At a meeting held under the Chatham House Rule, anyone who comes to the meeting is free to use information from the discussion, but is not allowed ever to reveal the identity, employer or political party of the person making a comment. It is designed to increase openness of discussion of public policy and current affairs, as it allows people to express and discuss controversial opinions and arguments without suffering the risk of dismissal from their job, and with a clear separation from the opinion and the view of their employer.
- The rule allows people to speak as individuals and to express views that may not be those of their organisations, and therefore, encourages free discussion. Speakers are free to voice their own opinions, without concern for their personal reputation or their official duties and affiliations. The Chatham House Rule resolves a boundary problem faced by many communities of practice, in that it permits acknowledgement of the community or conversation, while protecting the freedom of interaction that is necessary for the community to carry out its conversations. It is designed to reduce the risk of what has come to be described as groupthink, where unpopular views are excluded from discussion, reducing the range of opinions an organisation can discuss.
