Via the New York Times:

PHILADELPHIA — A state court ruled Friday that Philadelphia was not entitled to set its own gun laws, invalidating five measures passed by the City Council last year and striking a blow against the city’s efforts to strengthen gun control...

 

“While we understand the terrible problems gun violence poses for the city and sympathize with its efforts to use its police powers to create a safe environment for its citizens,” the five-judge panel wrote in a 21-page opinion, “these practical considerations do not alter the clear pre-emption imposed by the legislature.” The decision was by a vote of 4 to 1.
