The IDD Rule is based on the Chatham House Rule and is designed to foster free, open, and forthright discourse amongst participants in designated meetings and events held under the auspices of IDD. Normally, the person chairing the meeting can, either at his or her own discretion or at the request of one or more participants, invoke that said meeting or event, in whole or in part, is “taking place under the IDD Rule.” This may also be indicated in the invitation to the meeting or event, with a hyperlink to this page.

The underlying logic of the IDD Rule is that participants may be inclined to speak with greater frankness when they are made aware that their views will neither be attributed by others present or recorded.
 
The IDD Rule reads as follows:
 
“When a meeting or event, in whole or in part, is held under the IDD Rule, participants are free to make use of the views expressed therein in their future endeavors on the condition that neither the identity nor the affiliation of any speaker or participant is revealed.”
 
While the linguistic formulation of the IDD rule is not identical to the Chatham House Rule, the intellectual spirit animating its establishment is quite similar. For further information, including a helpful list of FAQ, please click here.
