The Trump administration was dealt another court blow Thursday as a federal judge in Massachusetts temporarily blocked Immigration and Customs Enforcement and the Department of Homeland Security from using taxpayer address information obtained from the IRS.

The ruling comes in a lawsuit filed by several community organizations challenging data‑sharing agreements that allowed ICE to request and receive taxpayer addresses for immigration enforcement purposes, according to court documents obtained by Politico's Kyle Cheney.

The court found that the plaintiffs were likely to succeed on their claim that the arrangements violated strict confidentiality protections, which limit when and how the IRS may disclose “return information,” including names, addresses, and taxpayer identification numbers. Judge Indira Talwani emphasized that Congress designed the statute “to protect the privacy of tax return information and to regulate in minute detail the disclosure of this material.”
