The Justice Department is suing four states after they refused to issue confidential license plates to federal law enforcement agencies, despite having done so in the past.

The lawsuits, filed Wednesday in Oregon, Washington, Massachusetts and Maine, seek to force states to resume what the federal government describes as long-standing, routine policies.

The scope of the combined litigation raises questions about ways the federal government has aggressively carried out immigration enforcement since President Donald Trump’s reelection, and whether the Constitution grants states the power to deny federal law enforcement agencies license plates that effectively conceal officers’ identities.

“Oregon’s DMV policy illegally discriminates against the United States, violates the Supremacy clause, and is unconstitutional,” attorneys for the federal government argued in court filings.

Oregon DMV temporarily paused disbursing new undercover license plates to all federal agencies starting April 15.

“The DMV is currently evaluating the undercover vehicle registration program to ensure the program complies with Oregon law,” Oregon DMV Administrator Amy Joyce explained in a May 22 letter to Assistant Attorney General Brett Shumate.

A recent lawsuit filed against Oregon State Police alleges the state is providing personal information to federal immigration authorities through databases, including Oregon’s DMV.

“If the DMV process for issuing undercover plates could be questioned under Oregon law, the State is at risk for additional litigation,” Joyce explained in the letter to Shumate.

The state’s review of the undercover license plate program doesn’t prevent federal vehicles from legally driving on Oregon roads.

“State and local law enforcement are unaffected by this pause and the federal agencies that participate in the program are able to continue to use their existing unexpired plates,” Kevin Glenn, a spokesperson for Gov. Tina Kotek wrote in a statement.

Immigration officers have relied on these license plates for enforcement, including during Operation Black Rose in Oregon and Washington. According to U.S. Immigration and Custom Enforcement, officers arrested more than 1,498 people between September and March, which led to 1,057 removals.

The lawsuits filed Wednesday argue the states’ DMV policies undermine ongoing federal investigations.

“Federal law enforcement agencies should not be subject to the challenged DMV policy, which is unconstitutional and recklessly disregards officer safety, public safety, and federal operational needs‚" the Justice Department’s lawsuit states.
