Verizon has filed a legal appeal challenging the FCC's authority to enforce the new net neutrality rules.
The government says it wants to ensure and open Internet.
Verizon says the rules are illegal.
A divided Federal Communications Commission adopted the rules last month that give the agency regulatory power over Internet service providers.
The new rules prohibit phone and cable companies from favoring or discriminating against Internet content and services that travel over their networks such as Skype which can compete with companies like Verizon.
