The Slovaks have already published a draft law on GDPR
Our Slovak neighbours have already published a draft law on the protection of personal data. It is more than likely that the Slovak proposal will be very similar to the Czech one.
The year 2017 is coming to an end and unlike us, the Slovaks are not waiting and procrastinating and have already published a draft law that will address the European GDPR data protection regulation.
If you want to be prepared, it is definitely worth studying it, as it is very likely that the Czech version of the law will be very similar.
