You can't actually force them though, if they just point blank refuse to vote what are they supposed to do, have Dermot sack them live on air? If you go to them last whatever decision they make will have some outcome on the result meaning really they have voted regardless. Abstain and they've ended up leaving the existing majority to send an act home (when Kelly did this it was ****ing moronic) or vote and send it to deadlock. Whichever way they're backed into a corner that forces them to affect the outcome some way.

Also I can understand abstaining, say you vote first and the act that you voted for stays after the other judges vote in a 3-1 majority or deadlock, you've then got to work with an act you sent home...not exactly the greatest atmosphere really.
