What it means for the Supreme Court to throw out Chevron decision, undercutting federal regulators

WASHINGTON — Executive branch agencies will likely have more difficulty regulating the environment, public health, workplace safety and other issues under a far-reaching decision by the Supreme Court.

The court's 6-3 ruling on Friday overturned a 1984 decision colloquially known as Chevron that has instructed lower courts to defer to federal agencies when laws passed by Congress are not crystal clear.

The 40-year-old decision has been the basis for upholding thousands of regulations by dozens of federal agencies, but has long been a target of conservatives and business groups who argue that it grants too much power to the executive branch, or what some critics call the administrative state.

The Biden administration has defended the law, warning that overturning so-called Chevron deference would be destabilizing and could bring a “convulsive shock” to the nation's legal system.

Chief Justice John Roberts, writing for the court, said federal judges “must exercise their independent judgment in deciding whether an agency has acted within its statutory authority.”

The ruling does not call into question prior cases that relied on the Chevron doctrine, Roberts wrote.
