US Court of Appeals for the District of Columbia Circuit is about to make one of the most important decisions in the history of the Internet

If you thought the battle over network neutrality ended when the Federal Communications Commission slapped a series of unprecedented rules on Internet providers, think again.

For months, the tech and telecom industries have been waiting for a court decision on net neutrality. It's the result of a legal appeal filed by companies such as AT&T and trade groups like the National Cable and Telecommunications Association. The lawsuit could overturn some or all of the rules, and nobody is quite sure how it'll turn out. Any day now, the court is expected to release its decision — and many in Washington are bracing for the result. Here's why it's so important, and what you need to know to get caught up. Anything could happen, but court-watchers say that the US Court of Appeals for the District of Columbia Circuit will uphold the most important piece of the FCC's new regulations: reclassification.
