Q & A for Adam's Mark Pickets August 10-11, 2001

Q: Why is the NAACP calling for a massive, all-out boycott of the Adam's Mark hotel chain?

A: The NAACP is boycotting the Adam's Mark hotel chain because in 1999, the NAACP, (on behalf of some hotel guests and visitors) the U.S. Department of Justice and the State of Florida filed separate lawsuits against Adams Mark, saying that the hotel chain violated the Civil Rights Act of 1964 (public accommodations law guaranteeing every citizen the right to use equally hotels, parks, restaurants and other public places). These lawsuits were filed after people attending Black College Reunion Weekend in Daytona Beach, Fla. alleged that as guests at Adam's Mark, they were forced to wear non-detachable, neon orange identification wristbands, forced to enter the hotel through barricades and a heavy police presence, and rented only the most basic rooms. Although, Adam's Mark initially agreed to an NAACP's $ 8 million settlement, the trial judge refused to approve the settlement on procedural grounds. That decision is on appeal and Adam's Mark has refused to support the appeal, or to otherwise settle the guests' and the State the State of Florida's case, the NAACP called for an all-out boycott of the hotel chain at our National Convention in July.

(Please note that the settlement was not approved by the judge because of "procedural grounds". Nothing more is said anywhere about which procedures or whose procedures were not correct)
