I'm slightly confused here; the EU Directive you are listing has absolutely no bearing on this discussion or the case at all?
https://eur-lex.europa.eu/eli/dir/2011/92/oj/eng
Article 5.2 concerns environmental impact assessments?
Even ignoring all this, Directives do not themselves automatically become enforceable in member State's legal systems either - "Regulations" do, and this is not one, the trial will be conducted subject to Danish criminal law.
Hmm… “DIRECTIVE 2011/92/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 13 December 2011, on combating the sexual abuse and sexual exploitation of children and child pornography, and replacing Council Framework Decision 2004/68/JHA”
I wonder if made a mistake, but that's the one I had open. I understand it doesn't impose specific penal choices, but I still think the punishment was fairly lenient.
