The U.S. Supreme Court rejected Florida's policy of making convicted murders eligible for execution if their IQ tests are 70 or above, USA Today reports. Florida must apply a margin of error to IQ tests administered to Freddie Lee Hall, convicted of killing two people in 1978. Justice Anthony Kenndey, author of the majority opinion, said: "'Florida's law contravenes our nation's commitment to dignity and its duty to teach human decency as the mark of a civilized world. The states are laboratories for experimentation, but those experiments may not deny the basic dignity the Constitution protects."'
