What is the Chatham House Rule?
The Chatham House Rule is used in meetings where participants need a way to openly share information, but don't want to be identified as the source of that information in any meeting records or articles written afterward. The rule is invoked regularly in meetings dealing with sensitive topics. It reads:
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.
