What is the Chatham House Rule?


The Chatham House Rule is a principle governing the confidentiality of discussions at certain meetings, which enables participants to freely express their views without fear of being directly quoted. The core of the Rule states, “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.

To put it simply, the Rule encourages openness and the free exchange of information and ideas, especially in sensitive discussions that involve politics, diplomacy, or business.

A Brief History of the Chatham House Rule

The Chatham House Rule was established in 1927 by the Royal Institute of Internal Affairs, which is based in London. The Rule was created to foster frank conversations on international policy and diplomacy, particularly among political leaders, diplomats, and business executives. Over time, the Rule has been widely adopted by organizations and forums globally, becoming a standard tool for ensuring confidentiality in high-level meetings. 

Are Chatham House Rules legally binding?

The Chatham House Rule is not legally binding. It is an informal agreement between participants and relies on mutual trust rather than legal enforcement. If a participant breaches the rule, there are typically no formal legal consequences. However, doing so can damage professional reputations, trust, and relationships. In high-level settings, the violation of the rule can result in a participant being excluded from future meetings or losing access to confidential discussions.

In some cases, organizations may include formal agreements, such as non-disclosure agreements (NDAs), alongside the Chatham House Rule to reinforce confidentiality. While the rule itself lacks legal force, such NDAs or other formal mechanisms can provide legal consequences when breached.

What does it mean to waive the Rule?

Waiving the Chatham House Rule means that the confidentiality it guarantees is either partially or fully lifted. This can happen in several ways. For example, a speaker may explicitly choose to be identified, or the entire meeting may agree that comments and identities can be openly attributed. Waiving the rule allows for more transparency, and it can be important in cases where accountability or public acknowledgement of statements is required.

However, once waived, the meeting no longer offers the protective environment that the rule is designed to provide, which can stifle open communication. In some situations, a partial waiver may be used, where certain sections of a meeting remain under the rule while others are made open for attribution.

What’s the difference between the Chatham House Rule and the Vegas Rule?

The difference between the Chatham House and the Vegas Rule lies in what participants are allowed to share after the meeting. The Vegas Rule, popularized by the saying “What happens in Vegas, stays in Vegas,” implies that nothing from the meeting is to be shared at all. It is an informal rule that emphasizes absolute secrecy. 

The Chatham House Rule, on the other hand, allows for the use of the information discussed but prohibits the attribution of specific statements to individuals. Therefore, striking a balance between confidentiality and the dissemination of ideas, whereas the Vegas Rule calls for complete silence regarding all meeting aspects.
