On 20 July 2018, an amendment to the current Data Protection Act adopted by the Liechtenstein Parliament in June will also come into force as transitional legislation until the new totally revised Data Protection Act is applied in future to supplement the GDPR. The new legal framework on data protection will give citizens better control over their data and businesses will benefit from a level playing field in Europe.
The decision of the EEA Joint Committee to incorporate the GDPR into the EEA Agreement will be published in the Liechtensteinische Landesgesetzblatt when it enters into force and can then be downloaded from https://www.gesetze.li/chrono/neueste-lgbl abrufbar.
Switzerland is thus the only country in Europe without direct application of the GDPR. Nevertheless, it particularly affects those companies that supply goods and products to customers in the EU or monitor their behaviour, e.g. using analysis tools under certain circumstances.
