The Supreme Court’s decision Monday saying that cable companies do not have to share their networks with competitors did not please Internet Service Provider EarthLink.

“Today’s Supreme Court ruling is a blow to consumers and competition,” said Dave Baker, EarthLink’s vice president for law and public policy. “For too long, cable companies and the FCC have denied consumers a choice of broadband providers over cable. Besides keeping prices high, this lack of choice limits the future deployment of innovative voice, video and data services beyond just those offered by the local cable company.”

The Court’s decision in the so-called Brand X case affirmed a stand taken by the Federal Communications Commission.

“I am pleased that the U.S. Supreme Court has affirmed the FCC’s ruling,” said Kevin Martin, the FCC chairman, in a statement. “This decision provides much-needed regulatory clarity and a framework for broadband that can be applied to all providers. We can now move forward quickly to finalize regulations that will spur the deployment of broadband services for all Americans.”

The FCC has said that forcing telecommunications companies to share their networks discouraged these firms from making further investments and expanding services.

“The Brand X verdict, while officially hinging on a technical distinction between different categories of network services, could have a dramatic effect on broadband growth and the future of the U.S. economy as a whole,” said Braden Cox, technology counsel at the Competitive Enterprise Institute, in a statement. “When telecommunications companies can be assured that they will control access to their own networks and are able to set prices accordingly, we can expect to see a significant increase in funds invested in broadband deployment.”

EarthLink, meanwhile, said it would continue to work with network providers to offer its own brands of high-speed Internet access.

“EarthLink will continue to serve broadband customers across the country with high-quality data and voice services and an innovative suite of protection tools,” Baker said. “We will also work with Congress as it revisits the (federal) Telecommunications Act in order to ensure customer choice and the future deployment of advanced communications services and applications.”
