Suit Against the State of Massachusetts Over Confidential/Undercover Licensing Policy

(filed May 27, 2026) 

U.S. v. Commonwealth of Massachusetts, et al. - The Trump Administration sued the state of Massachusetts over its confidential/undercover license plates policy. The government alleges that in 2026 Massachusetts’s Registry of Motor Vehicles (RMV) changed its policy and refused to issue confidential license plates to CBP and ICE. The complaint further alleges that, in a letter to the DOJ, Massachusetts explained that the policy distinguishes between law enforcement engaged in civil investigations versus those engaged in criminal investigations, among other things. The government challenges the policy primarily because it discriminates against the federal government. The federal case is ongoing.
