IAA SETI Committee
The IAA SETI Committee is described as the world’s primary international body dedicated to the scientific, technical, and societal aspects of the Search for Extraterrestrial Intelligence. It operates under the international-academy-of-astronautics (IAA) and is the steward of the post-detection-protocols — the Declaration of Principles governing how a detection of extraterrestrial intelligence is verified and announced.
It is currently chaired by Professor Michael Garrett (University of Manchester). Members include Bill Diamond, President and CEO of the SETI Institute.
In June 2026 the Committee announced the IAA’s ratification of a major revision of the post-detection protocols — the first in over 15 years — emphasizing independent verification before announcement, full-spectrum technosignatures, researcher protections, and the reaffirmed “No Reply” principle requiring united-nations consultation (src-seti-detection-protocols-revision-2026-06). The Committee will establish a permanent Post-Detection Sub-Committee of social-science, legal, and ethics experts.
