The Supreme Court's judgement in the Chugai case on April 18, 1960, after the restoration of sovereignty, ruled that the Red Purge of key industries was an "extra-constitutional measure at the direction of GHQ, and therefore that dismissals could not be contested," ruling in favour of the defendants and setting a precedent for subsequent cases. In 2011, three people who were dismissed in the Red Purge lost their lawsuit for compensation.
