The Federal Communications Commission's hopes of enforcing net neutrality rules was dealt a major setback last week. A panel of appeals court judges blocked the regulations on Thursday in a ruling that said broadband providers are likely to win the case on the merits.

The US Court of Appeals for the 6th Circuit previously issued an administrative stay that delayed enforcement of the rules for a few weeks, which didn't necessarily indicate much about the judges' view of the lawsuit. But on Thursday, the judges issued an order that stays the net neutrality rules until the court makes a final ruling, and judges made it clear they believe the Internet service providers have a stronger case than the FCC.

"Because the broadband providers have shown that they are likely to succeed on the merits and that the equities support them, we grant the stay," a panel of three judges wrote in the unanimous ruling.
