Are you certain this has happened? I never heard that happen in central Europe. I am pretty certain legislation of other countries is irrelevant, unless it would be an EU regulation - and I am unaware of an EU regulation that could bypass local laws and that has not been made a EU law. Which EU law specifically do you refer to?
