National Council of La Raza v. DEPARTMENT OF JUST.
Plaintiff advocacy organizations brought an action against the Department of Justice under the Freedom of Information Act (FOIA) to compel the production of records concerning the authority of state and local police to enforce immigration laws. The Department withheld documents, asserting the deliberative process privilege under FOIA Exemption 5. The Court found that while most withheld documents qualified for the privilege, the Department had waived it for a key April 2002 Office of Legal Counsel (OLC) memorandum by publicly incorporating its conclusions into agency policy. Consequently, the court partially granted and partially denied the Department's motion for summary judgment, ordering in camera review for some documents and directing the production of the April 2002 OLC memorandum to the plaintiffs.
