In a setback for industry groups, the U.S. Supreme Court on Monday announced that it would not take up challenges to Obama-era "net neutrality" regulations that barred internet service providers from giving certain customers preferential treatment.

The Trump administration overturned those regulations last year, and since June they have not been in effect. But a range of challenges to the regulations remained before the court, brought by groups such as the United States Telecom Association, AT&T and The Internet & Television Association.

The court's decision will leave in effect a decision from a federal appeals court in Washington upholding the constitutionality of the regulations. That means the decision can be relied on for precedent in the future.

Three of the court's conservative justices, Clarence Thomas, Samuel Alito and Neil Gorsuch, said they would have vacated that decision. Chief Justice John Roberts and Justice Brett Kavanaugh recused themselves.
