The Raiders and Al Davis have been involved in several lawsuits throughout their history, including ones against the NFL. When the NFL declined to approve the Raiders' move from Oakland to Los Angeles in 1980, the team joined the Los Angeles Memorial Coliseum Commission in a lawsuit against the league alleging a violation of antitrust laws. The Coliseum Commission received a settlement from the NFL of $19.6 million in 1987. In 1986, Davis testified on behalf of the United States Football League in their unsuccessful antitrust lawsuit against the NFL. He was the only NFL owner to do so.
