1971 test, the committee chartered a ship it renamed Greenpeace. During the voyage to Amchitka, the test was delayed a month. The ship was turned back by the U.S. Coast Guard, although a letter given to the Greenpeace crew showed support of the protest by some on the intervening Coast Guard ship. Under the Greenpeace name, the organization created for the protest continued to exist as the campaigning environmental organization Greenpeace. In July 1971, the anti-nuclear Committee for Nuclear Responsibility filed suit against the Atomic Energy Commission, asking the court to stop the test. The suit was unsuccessful, with the Supreme Court denying the injunction by 4 votes to 3. The test was carried out and did not cause a tsunami as feared.
