The Netherlands does not have a constitutional court and judges do not have the authority to review laws on their constitutionality. International treaties and the Statute of the Kingdom, however, overrule Dutch law and the constitution, and judges are allowed to review laws against these in a particular court case. Furthermore, all legislation that is not a law in the strict sense of the word (such as policy guidelines or laws proposed by provincial or municipal government) can be tested on their constitutionality.
