Isnt there any legislation that can sanction them?
Some countries have already included criminal sanctions for this type of dumping in their legislation, but the European Union does not, in this case, have a framework directive that establishes minimum sanctions, which means that there is a huge disparity between laws. The same type of dumping, depending on whose waters it takes place in, can result in a prison sentence or just an administrative sanction. Meanwhile, when dumping takes place on the high seas, there is a huge legal vacuum that tends to leave many violations unpunished.
