In 2018 the EU commission adopted a new approach on the protection of personal data in trade agreements. This new approach was a major improvement over earlier ones based on GATS article XIV, which contain conditions, among them a necessity test. The strength of the 2018 proposal is threefold.
First, the recognition that the protection of personal data and privacy are fundamental rights.
Second, the creation of a positive right:
“Each party may adopt and maintain the safeguards it deems appropriate to ensure the protection of personal data and privacy, including through the adoption and application of rules for the cross-border transfer of personal data.”
Only after that comes “Nothing in this agreement …”, which is more limited, as it does not cover for instance earlier agreements.
Third, the new approach also ruled out supranational investor-to-state dispute resolution.
The EU used the 2018 approach in trade agreements with New Zealand (article 12.5) and Chile (article 19.6).
Unfortunately, in the agreement with the UK the EU used a weaker safeguard. The mention of data protection and privacy as a fundamental right went missing and the parties used other formulations.
