The US Telecom Association, an alliance led by incumbents AT&T and Verizon (Engadget's parent company), had taken action against the FCC rules in 2016 arguing that it overstepped its bounds by classifying broadband as a telecom service subject to common carrier rules, and thus net neutrality regulation. The DC court determined that the reclassification was reasonable, but the USTA promptly petitioned the Supreme Court contending that the FCC didn't have the power to issue the order.

The catch, of course, is that the Trump-era FCC has repealed net neutrality. This covers rules that are no longer in effect, and it doesn't bring them back. That's not to say this decision is pointless, however. Net neutrality advocates are betting that the DC ruling will support the legal challenge to the repeal. The Supreme Court's choice preserves that support -- if it had heard the appeal and overturned the lower court, the case for net neutrality would have been that much weaker.
