AT&T is dropping a court challenge to the Federal Trade Commission’s (FTC) authority over telecommunications providers, ending a legal battle that critics said could have left the post-net neutrality internet with little oversight.

In a court filing on Wednesday, AT&T’s lawyers said that the telecommunications giant would not be petitioning the Supreme Court for a review of a federal appeals court decision that said the FTC had jurisdiction over them.

In February, the full Ninth Circuit Court of Appeals had overturned an earlier ruling that said the FTC couldn’t take action against companies that engage in the telecommunications business because telecom companies are common carriers with less legal liability.
