Supreme court:

In the Netherlands, the Supreme Court of the Netherlands is the highest. Its decisions, known as "arresten", are absolutely final. The court is banned from testing legislation against the constitution, pursuant to the principle of the sovereignty of the States-General; the court can, however, test legislation against some treaties. Also, the ordinary courts in the Netherlands, including the Hoge Raad, do not deal with administrative law, which is dealt with in separate administrative courts, the highest of which is the Council of State (Raad van State)
