European Directive 2012/29/EU on the rights of victims... if the state introduces some guidelines into the law but does not fulfill them in practice - let's say that the law of the state says that the victim must get the necessary information and help, but then in practice he does not get it because workers do not comply with the law correctly. What then is the legal argumentation from the point of view of EU law?

But what if it is implemented in such a way that they are not effective? What then is the legal argument then?
