Parks' action is in relation to the rap duo's 1998 track entitled 'Rosa Parks'. The song did not misrepresent Ms Parks, who famously refused to give up her seat on a segregated bus to a white man in 1955, but as her permission was not obtained for the title, Outkast and La Face could still lose out, and expensively so.
The Supreme Court threw out a claim that Outkast had defamed 90-year-old Parks' character, but allowed the claim that the duo had used her likeness without permission to stand. Neither Outkast or La Face have commented on this decision as yet.
