It is constitutional? I don't know about Dutch constitution, but there usually is something about privacy, and presumption of innocence, and even if it isn't in the constitution (constitution is mostly about the technicalities of governance), there are things like the Declaration of Human Rights and other treaties that mention it that are above the law.
