What it's about

The Supreme Court overturned the Sixth Circuit, accepting the FCC’s reasonable interpretation that federal law requires access at those rates when the lines are used for interconnection.

The dispute concerned whether federal rules requiring established local phone companies to share network access with competitors also covered existing lines used to connect networks.

Question presented

Does federal law require local telephone companies, already established, to allow new competitors in their markets to link to the existing networks through connecting wires at low, government-regulated rates?

What the Court decided

Holding

The FCC has advanced a reasonable interpretation of its regulations— i.e., that to satisfy its duty under §251(c)(2), an incumbent LEC must make its existing entrance facilities available to competitors at cost-based rates if the facilities are to be used for interconnection—and this Court defers to the FCC’s views. 597 F. 3d 370, reversed.

Result
Reversed

The Court's reasoning

The Court said the Federal Communications Commission reasonably interpreted its rules to require incumbent phone companies to provide existing network-connection lines at cost-based rates when competitors use them to connect networks. The Court deferred to the agency’s interpretation.
