The U.S. Supreme Court issued several significant rulings that limit federal agencies' regulatory powers, sparking a wave of legal activity and altering the landscape of administrative law. Key decisions include requiring jury trials for civil penalties imposed by agencies, overturning the 'Chevron deference' precedent, and extending the statute of limitations for regulatory challenges. These rulings are expected to increase litigation against regulatory agencies and potentially reshape financial and environmental regulations. Additionally, the Court narrowed the application of charges related to obstructing an official proceeding, impacting cases from the January 6 Capitol riot and former President Trump's indictment. The Supreme Court may also reconsider the constitutionality of modern federal commissions in its next term, potentially leading to further substantial changes in administrative governance.
