The Supreme Court’s latest climate change ruling could dampen efforts by federal agencies to rein in the tech industry, which went largely unregulated for decades as the government tried to catch up to changes wrought by the internet. Thursday’s 6-3 decision was narrowly tailored to the Environmental Protection Agency. The court ruled that the EPA doesn’t have broad authority to reduce power plant emissions that contribute to global warming. The precedent is widely expected to invite challenges of other rules set by government agencies.
