The family of Martin Luther King Jr. took cbs to court last year to try and prevent them from using King’s ‘I Have a Dream’ speech in a video on the civil rights movement.

The King family argued that the speech, which was delivered in Washington in 1963 to 200,000 people, should be considered the private and personal property of King, in the same way a play or any other literary creation would. The speech, they argued, was a public performance of a private work, and therefore the rights should remain the sole property of the King Foundation in Atlanta.

The Supreme Court, however, did not share the view, and ruled that the speech was in the public domain.
