Court Ruling Curtails Administration’s Ability to Terminate Grants Based on New Priorities

On March 24, 2026, the U.S. District Court for the Northern District of Illinois decided that federal grantees can challenge grant terminations by the Administration if at the time of termination the grantees were compliant with Administration policies that were in place at the time the grant was awarded, as opposed to new rules or policies subsequently imposed by the Trump Administration. This decision could aid federal contractors and grantees in their legal challenges to the numerous contract and grant terminations, which have occurred since January 2025, based on alleged failure of the contracts or grants to align with or effectuate new Administration programs, policies, goals, and/or priorities, including, but not limited to, those relating to diversity, equity and inclusion (DEI) programs and policies.
