The manifestos of almost half the main parties contesting the March general election include measures which go against the Dutch constitution, according to research by the Dutch law society Nova.

The law society looked at 13 manifestos and found measures which would weaken the rule of law in most of them and proposals which are illegal in five. Most of the measures concerned dealing with terrorism, jihadism, refugees, Islam and immigration.

‘These challenges ‘are pressuring the foundation of our legal system,’ Nova said. However, solutions are not found in going against fundamental human rights and freedoms, the lawyers organisation says in the NRC.

In particular, the one-page manifesto drawn up by the anti-immigration PVV contains a number of points which conflict with international treaties and Dutch laws, Nova said.

In addition, the Christian Democrats want to ban foreign funding of mosques, VNL wants to ‘de-naturalise’ dual nationals with a criminal conviction and the VVD wants to render people who join terrorist organisations stateless.

All these measures conflict with human rights or are openly discriminatory against certain population groups, the commission said.

A comparison of this year’s manifestos which those published before the 2012 general election shows a ‘considerable increase’ in discriminatory proposals.
