First of all you are assuming that the laws themselves are obeyed by the government in the Netherlands. They are not. All of the written guidelines are simply ignored. No one checks that they obey them and no one can getting any consequences applied to the violation of them.
The Dutch government is in a race to the bottom with respect to human rights over the last 20 years. It started around 2005, 4x years ago what was called the IRT affaire scandal in which the government themselves had become the biggest drug imported in Europe.
After then was discovered and cause a media fallout, 4 years later they started again but using a new approach in which they spread the blame and make it even harder to become accountable. In 2006, the councils started signing documents like the "Integrated approach to dealing with hennep plantations" in which they centralized the control of the intelligence, but spread the blame and the actions associated with this across the police, the council, the tax department and now there are about 9 partners or so.
This became so successful in their eyes that they formalized this at the end of 2008 and formed the RIEC, which stands for regional information and expertise centrum, which is an intelligence agency that is formed with a human representative so you cannot legally take this organisation to court under Dutch law and this organization does it's dirty work through it's parters, the police, council, tax department etc.
In addition, they expanded the scope of what they do. They no longer just find evidence and convict. Now they are able to "Interfere" with who they claim is involved with organised crime. And they are no limits to what interference means and there's no evidence required to do this, simple what's called "A reasonable suspicion". i.e. nothing.
Then in 2020 they changed to the law so that any one that works in a job that has an obligation to secrecy cannot be found guilty of perjury. They example they came at the time was "For example, a lawyer has an obligation to secrecy for his client". However, that was just a smoke screen. What they did was make it so that everyone in government now can lie in court under oath and not be prosecuted. Including prosecutors themselves. And if you don't believe this I've seen a document written by the attorney general in which he quite plainly states that a prosecutor cannnot be found guilty of perjury.
And believe me, even in places like the UK of the US prosecutors can be found guilty of obstruction of justice. Not in the Netherlands.
By allowing prosecutors and any government official to lie in court, they have effectively simply made all of the court proceedings in the Netherlands be a shame. As there is zero integrity. Clearly this also includes the international criminal court. It's located in the Netherlands after all.
