What happened later?
ITER — legal status and privileges agreements: ITER’s own legal-status record describes the seven-member agreement and the separate privileges agreement entering into force in October 2007.
What does that evidence establish?
This U.S. statutory designation is distinct from the treaty’s operation in France and does not pre-decide a particular immunity dispute. Designation is not a claim about the project’s technical progress. The signed order states the original requirements.
Who had to do what
Federal officials applying the International Organizations Immunities Act must recognize ITER’s designation as a covered public international organization; the signed order assigns no agency-specific task or deadline. Signed Federal Register text
