The U.S. Supreme Court agreed Friday to review whether a fund managed by the Federal Communications Commission (FCC) to improve phone and internet services is legal.

The court’s review responds to allegations that Congress improperly delegated its authority to this independent agency, according to Reuters. The FCC, alongside a consortium of interest groups and telecommunications companies, is appealing a decision from a lower court that ruled such delegation unconstitutional.

The Supreme Court is set to hear the case and deliver its decision by late June, Reuters reported.  Established under the 1996 Telecommunications Act, the Universal Service Fund, managed by the FCC, allocates approximately $9 billion annually.
