The U.S. Supreme Court's recent decision to overturn the Chevron deference doctrine will significantly impact federal regulations' interpretation, affecting donors and nonprofit organizations. This decision curbs the power of federal agencies, particularly the IRS and Treasury Department, aiming to limit unchecked administrative authority. The ruling weakens the role of the federal bureaucracy by reducing unelected bureaucrats' power and expanding agencies' executive power. Additionally, the Chevron ruling could lead to legal challenges on various policies such as workplace safety, healthcare coverage, and environmental regulations, potentially reshaping regulatory landscapes across different sectors.
