New York City has filed an amicus brief with 27 other local governments and mayors in support of the petitioners in the case against the Federal Communications Commission order ending net neutrality.

The brief led by Zachary Carter, corporation counsel for the New York City law department, was filed Monday Aug. 27 in the U.S. Court of Appeals for the District of Columbia Circuit in the petition for review titled Mozilla Corp. et al vs. Federal Communications Commission and the United States of America 18-1051(L) and consolidated cases. The FCC order ending the Obama-era regulation requiring all internet traffic to be treated equally took effect in June. The cities’ brief in the petition asks the court to vacate the preemption provision of the FCC order. Oral arguments are not yet scheduled in the case.
