A federal appeals court has ruled the Federal Communications Commission lacks the authority to prevent internet service providers from blocking and controlling internet traffic. The FCC has long sought to force internet service companies to give web users equal access to all websites, a concept known as network neutrality. But the decision grants the companies further control over internet traffic while threatening the future of internet regulation. The ruling is a major victory for cable giant Comcast, which had challenged the FCC’s authority to impose network neutrality obligations on broadband providers.
