A federal appeals court on Tuesday upheld an injunction blocking the Internal Revenue Service from sharing taxpayer addresses with U.S. Immigration and Customs Enforcement. The U.S. Court of Appeals for the District of Columbia Circuit ruled that a procedure adopted under President Donald Trump’s administration violated federal law by allowing ICE to seek the last known addresses of as many as 1.28 million people suspected of unlawfully residing in the United States. The IRS had disclosed 47,289 records before a lower court blocked the policy. The panel said the process failed Section 6103 safeguards, including the requirement that ICE provide an actual address and protections for individual review. The case was brought by the Center for Taxpayer Rights and the Main Street Alliance, represented by Democracy Forward.
