The Clinic filed its brief along with the Center for Consumer Law and Economic Justice at UC Berkeley and the progressive think tank Demos. The Supreme Court will hear argument in the case on March 30, 2021. In 2008, TransUnion began marketing a product that matched potential consumers to the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) Specially Designated Nationals List (SDN List), a list of individuals understood to pose threats to national security and who are barred from doing business in the United States. The list contains names of terrorists and known drug traffickers, according to the brief. The brief states that TransUnion contracted with a third party that utilized an error-prone methodology to match consumer names to OFAC SDN List entries. Consumers were matched on the basis of only their names and sometimes only their last names and first initials.
