Broadband industry lobby groups have appealed to the US Supreme Court in an attempt to kill the Federal Communications Commission’s net neutrality rules. The groups want the Supreme Court to rule that the FCC exceeded its authority when it reclassified Internet providers in order to impose stricter regulations.

Under President Obama, the FCC’s Democratic majority reclassified home and mobile broadband providers as common carriers under Title II of the Communications Act in order to enforce net neutrality rules.

With Republicans now in charge, the FCC is on track to overturn the rules. But a Supreme Court decision in favor of Internet providers could protect them from future attempts to regulate the industry if, for example, Democrats eventually re-take the White House and FCC.
