Round-robin (document)

Round-robin is a document signed by multiple parties in a circle to make it more difficult to determine the order in which it was signed, thus preventing a ringleader from being identified. Sometimes this may also refer to the document signed when a crew makes a pact to rise up against their captain.

Origin
The term dates from the 17th Century French ruban rond (round ribbon). This described the practice of signatories to petitions against authority (usually Government officials petitioning the Crown) appending their names on a document in a non-hierarchical circle or ribbon pattern (and so disguising the order in which they have signed) so that none may be identified as a ringleader.

This practice was adopted by sailors petitioning officers in the Royal Navy (first recorded 1731).
