The US Supreme Court shot down the Biden administration’s controversial plan to forgive billions of dollars in federally-backed student loan debt, a decision that means millions will have to start making repayments later this year.

In a 6-3 decision down ideological lines, the justices held that the administration wasn't authorized to offer the debt relief under a 2003 law known as the HEROES Act. The Biden administration invoked that act during the initial stages of the COVID-19 pandemic as authorization for the student loan relief.
