DUBLIN (Reuters) - A move by Ireland's data regulator's in August to halt the transatlantic transfer of Facebook customer data threatened "devastating" and "irreversible" consequences for its business, a lawyer representing the U.S. company said.

Facebook is asking Ireland's High Court to review the preliminary decision by the Irish Data Protection Commissioner, which took action in August following July rulings on EU-U.S. data transfers by the Court of Justice of the European Union.
