What this means is that governmental "consumer agencies" have the right to take down websites in other EU states that sell illegal stuff to their country. A website like a fireworks store or even ebay can be taken down in all member states of the EU without prior notification, regardless of where the crime has been committed. This is very useful in certain cases like the "free promo scam" that they had in Holland a couple of years ago: A scammer had a website where they promoted free stuff worth 20 euro, but you had to pay shipping costs (6.95 euro). The website was even heavily promoted on radio and television channels, until they realized that they had been included in the scam (the cheque bounced). The total damage was unknown, but it ranged from 300k to 1 million euro in total. It took consumer organisations a few days to get the server taken down, mainly because the site looked legitimate in the first place and the ISP was not willing to take down a legitimate site.
Its like some form of "Cease to Exist" letter that governmental agencies can send to the ISP, without having to go to court first to get the website taken down (and to prevent further damage).
