It seems to me your intention here was not to point out the perceived wrongness of this particular decision, but to provide "yet another case of Brussels bureaucrats meddling in our lives". In doing that, you're purposefully confusing the lawmaking and judiciary parts of the legal system to create an imagined body which you creatively name the "Eurocracy", while this was a court decision independent of those actually making the law. In short, your intention was to rant, using this ruling as an excuse, and not to provide potentially interesting information.

As for the ruling itself, I don't see what's wrong with it. It's gender discrimination, and gender discrimination is (IMO rightly) unlawful. I have never been in a car accident, I'm a careful and relatively safe driver and I don't appreciate having to pay more just because I happen to be male.

I'm sure you can come up with statistics that show people of a certain ethnicity are more likely to be in an accident too, but insurance companies know that's a no-go. Discriminating by gender is exactly the same; it's based on something you are that you can't change, unlike driving experience and where you live which you can.
