Title 14, Section 1211 of the Code of Federal Regulations.

Adopted on July 16, 1969. Recended April 26, 1991.

This regulation gave the Administrator of NASA the extra-judicial right to quarantine under armed guard anyone who became “extra-terrestrially exposed.”

‘Quarantine’ means the detention, examination and decontamination of any persons, property, animal or other form of life or matter whatever that is extra-terrestrially exposed, and includes the apprehension or seizure of such person, property, animal or other form of life or matter whatever.”

The penalty for violating quarantine was up to $5,000, a year in jail, or both.

The law was a rallying cry for UFO enthusiasts who feared jail should they make contact, but most outcry occurred after the regulation had already been removed from the books.
