A federal judge on Monday refused to halt enforcement of the Los Angeles City Council’s newest outdoor advertising law, which bars the installation of new digital billboards and multistory supergraphic signs across the city.

Liberty had asked Collins to issue an injunction and force the city’s Building and Safety Department to allow 16 new signs to go up.

Los Angeles is fighting more than 20 legal challenges from the billboard companies opposed to its efforts to regulate outdoor advertising. The council approved a temporary sign ban in December, hoping to buy itself time to craft a new ordinance that would withstand a court challenge.
