The Internet Association [official website], along with a number of other trade groups, filed [PDF] a brief in the US Court of Appeals for the District of Columbia Circuit [official website] Monday urging the court to reinstate net neutrality rules.

The brief was filed in support of the petitioners, one of which is Mozilla Corporation, who filed suit against the Federal Communications Commission (FCC) and the US government. The petitioners are seeking “review of an Order of the Federal Communications Commission (FCC) that eliminates judicially-approved rules the FCC adopted in 2015 to protect and promote net neutrality and an open internet.”

The brief argues in support of net neutrality, saying that the FCC “unreasonably asserts that no neutrality rules … are needed to protect the open internet.” It also states that the FCC’s claim that “the costs of the net neutrality conduct rules outweigh their benefits” is a flawed analysis and that it is counter to the FCC’s own factual findings. It concludes by saying that “[b]ecause the Commission does not offer a reasoned basis for its decision to eliminate the conduct rules, the Order is arbitrary and capricious.”
