In his Atlantic Council issue brief US Surveillance on Trial in Europe: Will Transatlantic Digital Commerce Be Collateral Damage?, Propp summarizes the history, oral arguments, and possible outcomes of the European Court of Justice’s pending decisions on the validity of Standard Contractual Clauses and the EU-U.S. Privacy Shield. Propp notes that if the Court finds U.S. surveillance law is inconsistent with EU privacy laws, “transatlantic data transfer mechanisms relied upon by [Facebook], and thousands of other companies, may be invalidated.” The article examines the roots of this transatlantic privacy divide, traces the history of the Safe Harbor through the Schrems I case to the EU-U.S. Privacy Shield agreement, and analyzes the oral arguments made before the European Court of Justice in the Schrems II case.
