On March 24, the European Court of Justice ("ECJ") held an oral hearing in Schrems v. Data Protection Commissioner. The case involves a privacy activist challenging the Irish Data Protection Commissioner's decision not to investigate claims about improper data transfers to the U.S. by a social media website.

An opinion is expected in June.
