In 1980, President Jimmy Carter appointed a special commission to investigate the internment of Japanese-Americans during World War II. The commission concluded that the decisions to remove those of Japanese ancestry to prison camps occurred because of "race prejudice, war hysteria, and a failure of political leadership". In 1988, Congress apologized and granted personal compensation of $20,000 to each surviving prisoner.
In the early 1980s, while researching a book on internment cases, lawyer and University of California, San Diego professor Peter Irons came across evidence that Charles Fahy, the Solicitor General of the United States who argued Korematsu v. United States before the Supreme Court, had deliberately suppressed reports from the FBI and military intelligence which concluded that Japanese-American citizens posed no security risk. These documents revealed that the military had lied to the Supreme Court, and that government lawyers had willingly made false arguments. Irons found that the Supreme Court’s decision was invalid since it was based on unsubstantiated facts, distortions, and misrepresentations. Along with a team of lawyers headed by Dale Minami, Irons petitioned for writs of error coram nobis with the federal courts, seeking to overturn Korematsu's conviction.
On November 10, 1983, Judge Marilyn Hall Patel of U.S. District Court in San Francisco formally vacated the conviction. Korematsu stood in front of US District Judge Marilyn Patel and said, “I would like to see the government admit that they were wrong and do something about it so this will never happen again to any American citizen of any race, creed, or color.” He also said, “If anyone should do any pardoning, I should be the one pardoning the government for what they did to the Japanese-American people.”  Peter Irons described Korematsu’s ending statement during the case as the most powerful statement he’d ever heard from anyone. He related the statement as being as empowering as Martin Luther King’s famous “I Have a Dream” speech. Judge Patel’s ruling cleared Korematsu’s name, but did not overturn the Supreme Court’s decision.
President Bill Clinton awarded the Presidential Medal of Freedom, the highest civilian honor in the United States, to Korematsu in 1998, saying, "In the long history of our country's constant search for justice, some names of ordinary citizens stand for millions of souls. Plessy, Brown, Parks ... to that distinguished list, today we add the name of Fred Korematsu."
Judge Patel’s ruling cleared Korematsu’s name, but did not overturn the Supreme Court’s decision.
The SC can overturn a lower courts ruling, but when they don't, it becomes the law.
Our court system is not "playing games." You are stupid.
You're dumber than a rock. A rock has value to humans, and you have none.
I'm wondering if you know all of their reactions on 911. Did they cry or clap?
As a legal precedent it is now recognized as having very limited application
