Regarding this directive, I thought, as I already spent the time googling this stuff, this complementary documentation might come in handy :
Directive full texts in EU languages :
Reference to national law implementations :
As I read a few posts back someone stating the national law overrides EU directives, that is more or less accurate, in fact, directives have to be implemented into national law (member states have no choice and will be drawn to EU court if they don't), and until they are implemented, the old national law will indeed continue apply.
On the other hand this directive is 14 years old, so all member states should have implemented it in the meantime.
The last link being the most interesting as you can see in what texts this has been implemented to in the respective member states.
Using those texts, you should have more power to compell the reseller to fulfill his duties.
Just thought I would share...
