2. I was mainly talking about about (the effect of) overregulation in general, I did not say there is a specific regulation re volunteer firefighters. But if the implied problems become reality, it would be because of interpretation of laws and regulations.
Yes, there was a lawsuit in Belgium. And no, that's not the main issue that was reported here. Lawyers conducted a study of the practice of Dutch firefighting on behalve of the Ministry of Justice and Security, and concluded that the way our system is set up contradicts EU law. The main issue is that volunteer firefighters do almost exactly the same work as paid firefighers.
3. That's point 1.
4. This is exactly my more general concern about the EU: unintended consequences are inevitable when you are centralizing laws and regulations to the most detailed levels for over two dozen countries with very different contexts. There are plenty of EU laws and regulations for which I think the intent is very sensible, but where implementation can be problematic, or problematic for specific subsets of the regulation, or specific countries/regions.
5. I never said they happened, I said "will". Perhaps I should have said "may" since the problem might still be addressed somehow. But even if it is adressed, in the case of the Netherlands a massive change would be necessary. According to lawyers and law professors who have studied the problem in the Dutch context.
So no, not misinformation. I just worded it somewhat imprecise.
