The net neutrality litigation between the Federal Communications Commission and Verizon is heating up again. On May 22, Verizon sent a letter to the D.C. Circuit, arguing that the court’s decision in National Association of Manufacturers v. NLRB regarding an employer’s free speech rights supports Verizon’s position in the net neutrality case. The next day, the FCC responded with its own letter, saying that the recent Supreme Court ruling in City of Arlington v. FCC supports its argument that its interpretations of ambiguous statutory provisions are entitled to deference. On May 30, the FCC filed a letter rebutting Verizon’s assertions regarding National Association of Manufacturers. Not to be outdone, Verizon filed its own letter on June 3 responding to the FCC’s interpretation of City of Arlington. Stay tuned.
