Taxi drivers who discriminate based on race may face revocation of their permit to operate at Los Angeles International Airport. The stiff new penalties were approved late Tuesday by a Los Angeles City Council committee, according to FOX-LA (Channel 11). The tougher rules would result in the immediate revocation of a taxi driver’s permit to operate at LAX if he or she were found to have refused rides due to race or other discriminatory reasons. The new rules will next be considered by the full City Council.

Informal warnings would be eliminated under the new rules. Refusals of service for other reasons would result in no less than six days suspension from the airport, while discourteous actions could lead to suspensions lasting no less than four days.

The move toward more stringent anti-racist rules arose in the aftermath of a complaint in September filed by former Major League Baseball player Doug Glanville, who said he was refused a ride by a taxi driver at LAX because he is black.
