We didn't say there needed to be obligations. The reform could be useful for encouraging the parties to make sure the lists cover members of visible minority groups, people from remote regions, or people in city centres. We even said that a person could be both in a constituency and on the list. The party can say “vote for us, we have a star candidate in eighth place” and therefore have the seven preceding candidates elected. The list can be established strategically.
