The Supreme Court weakens federal regulators, overturning decades-old Chevron decision

WASHINGTON (AP) — The Supreme Court on Friday upended a 40-year-old decision that made it easier for the federal government to regulate the environment, public health, workplace safety and consumer protections, delivering a far-reaching and potentially lucrative victory to business interests.

The court's six conservative justices overturned the 1984 decision colloquially known as Chevron, long a target of conservatives. The liberal justices were in dissent. Billions of dollars are potentially at stake in challenges that could be spawned by the high court’s ruling. The Biden administration’s top Supreme Court lawyer had warned such a move would be an “unwarranted shock to the legal system.”

The heart of the Chevron decision says federal agencies should be allowed to fill in the details when laws aren't crystal clear. Opponents of the decision argued that it gave power that should be wielded by judges to experts who work for the government.

“Courts must exercise their independent judgment in deciding whether an agency has acted within its statutory authority,” Chief Justice John Roberts wrote for the court. Roberts wrote that the decision does not call into question prior cases that relied on the Chevron decision.
