The U.S. Supreme Court overturned the Chevron doctrine, impacting cybersecurity regulations and federal agency interpretations of laws. This decision could challenge recent cybersecurity measures, like the SEC's incident reporting requirements, and influence future regulations for critical infrastructure and healthcare. The ruling shifts power from agencies to the courts, potentially affecting EPA regulations and providing more certainty for farmers in challenging federal rules. Legal experts consider this a significant blow to federal regulations, empowering judges to interpret laws where ambiguity exists, with implications for various industries.
