This is an Italian case
Ratti was not complying with an Italian law about packaging of varnishes. There was an EU directive on this. The exisiting Italian law was stricter than the EU law.
The ECJ found for Pubblico Ministero – the state is allowed to go further than the EU law.
Italy had not yet implemented the directive – the deadline had not passed. It made no difference because the existing Italian law more than covered what was needed.
A state must meet the requirements of a directive and may go further if it wishes.
