On 21 February 2017, the Article 29 Working Party published guidance on handling complaints under the Privacy Shield (the "Guidance") consisting of:
(1) rules of procedure to enable organisations to bring complaints before an informal EU DPA panel ('rules of procedure for informal DPA panel'); and
(2) a complaint form that can be used by individuals to submit complaints to their country's data protection authority ('complaint form for commercial complaints').
The publication of the Guidance indicates that EU regulators are preparing for enforcement – a general trend ahead of the GDPR.
The Guidance can be accessed here.
