List of Dutch extradition treaties

There are, roughly speaking, four types of establishing dual criminality:

1. The enumeration system - In this system, the crimes which can lead to extradition are explicitly listed in the treaty. Dual criminality is however required.^[1]

2. The elimination system - In this system, there is no list. Dual criminality is established if the crime is punishable in both countries and is threatened with a minimum maximum penalty in both countries.^[2] The minimum maximum penalty is established in the treaty concerned. In case of extradition for execution, the treaty provides a minimum remaining term of sentence which still had to be served.^{[citation needed]}

3. The combination system - These are treaties with a list and a minimum maximum sentence.^[3] If the extradition cannot take place because the maximum penalty in one of the countries does not fulfill the minimum established in the treaty, extradition can still happen if the crime is listed in the treaty.^{[citation needed]}

4. All the above systems have the requirement that the crime must be punishable in both countries. Type number 4, the European Arrest Warrant (EAW), does not always have that requirement.^{[citation needed]} Requests from other EU member states are treated like the above mentioned combination system, with the exception for dual punishability. This is not required for crimes on the list.^{[citation needed]}
