"Los Angeles is fighting more than 20 legal challenges from the billboard companies opposed to regulation of outdoor advertising. The council approved a temporary sign ban in December, hoping to buy time to craft an ordinance that would withstand a court challenge.
In the weeks after that vote, Liberty challenged the moratorium, saying that exceptions had been made for "favored high-profile developments," including the W Hotel in Hollywood. The council responded in August by passing a permanent sign ban as advised by the city attorney's office."
One advertiser had hoped the court would overturn the city's ban on the ads, enabling him to install 16 more supergraphics on the sides of buildings throughout Los Angeles.
