RULE 1 International consultations should be initiated to consider the question of sending communications to extraterrestrial civilizations.
RULE 2 Consultations on whether a message should be sent, and its content, should take place within the Committee on the Peaceful Uses of Outer Space of the United Nations and within other governmental and non-governmental organizations.
RULE 3 These consultations should be open to participation by all interested States and should be intended to lead to recommendations reflecting a consensus.
RULE 4 The United Nations General Assembly should consider making the decision on whether or not to send a message to extraterrestrial intelligence, and on what the content of that message should be, based on recommendations from the Committee on the Peaceful Uses of Outer Space and from governmental and non-governmental organizations.
RULE 5 If a decision is made to send a message to extraterrestrial intelligence, it should be sent on behalf of all Humankind, rather than from individual States.
RULE 6 The content of such a message should reflect a careful concern for the broad interests and wellbeing of Humanity, and should be made available to the public in advance of transmission.
RULE 7 As the sending of a communication to extraterrestrial intelligence could lead to an exchange of communications separated by many years, consideration should be given to a long-term institutional framework for such communications.
RULE8 No communication to extraterrestrial intelligence should be sent by any State until appropriate international consultations have taken place. States should not cooperate with attempts to communicate with extraterrestrial intelligence that do not conform to the principles of this Declaration.
RULE 9 In their deliberations on these questions, States participating in this Declaration and United Nations bodies should draw on the expertise of scientists, scholars, and other persons with relevant knowledge.
IAA SETI Declaration of Principles
The IAA, in an attempt to draw up universal guidelines on the immediate steps to be taken by the group or individual that makes a discovery, drafted the "Declaration of Principles Concerning Activities Following the Detection of Extraterrestrial Intelligence".The following has been endorsed by six international professional space societies and also constitutes an informal agreement among most of those carrying out SETI. The declaration proposes a set of nine post-detection protocols, listed below.
These rules do not carry the force of law or any other regulatory power. Hence they can be ignored by public or private institutions should they choose to, without legal repercussions.
