Chatham House Rule

The Chatham House Rule allows participants to use information obtained in a meeting but forbids identifying the speakers or other participants, including their affiliations.

Context

It is an attribution rule, not a blanket promise that information discussed is confidential or may never be shared.

Why it matters for foreign affairs

It can support candid policy discussions between public officials and outside experts while preserving clear ground rules about attribution and disclosure.

Where it appears in practice

A roundtable moderator states that the Chatham House Rule applies and explains that substantive insights may be used without identifying who made them.

Clarification

Use the official singular “Chatham House Rule”; do not call it “Chatham House Rules.”
