I got wind of this through a Dutch Facebook friend.
The Motion's Sponsor is Kees van der Staaij leader of the Reformed Political Party, ie. a Christian party.
He reported the motion adopted on his Twitter.
I didn't find out anything else while Googling (i.e. the vote count and who supported or opposed it). Things are a little busy at the house, given it's Christmas time.
Are there any Dutch speakers who could fill us in?
