A Philadelphia ordinance banning the posting of signs on city utility poles, traffic signals and trees is not unconstitutional, the 3rd U.S. Circuit Court of Appeals has decided.

A unanimous three-judge panel ruled that the ordinance was content-neutral and narrowly tailored to serve a government interest, and that the underlying law only required the city to leave a speaker with alternative channels of communication. Those channels did not, however, have to be the most preferable to the speaker or the most cost-effective, the court said.
