A.6(5)(iii): This elimination procedure is repeated, moving down ballot papers to 2nd, 3rd, 4th, etc. preferences as required, until one option gets more than half of the `first' preferences. It seems to me to be clear that the intent is that if a ballot has no remaining preferences then it doesn't count when considering which option might have "more than half of the `first' preferences". Such a ballot couldn't be said to have a "`first' preference" any more, surely ? > In point 8, where Quorum is talked about, it states that for an > option to win, it must have X more votes for than vs. the default > option.

I > think the constitution implies that the vote ends there... A.6(8): 8.If a quorum is required, there must be at least that many votes which prefer the winning option to the default option. If there are not then the default option wins after all. For votes requiring a supermajority, the actual number of Yes votes is used when checking whether the quorum has been reached. The "winning option" here refers to the outcome of steps 1-7, clearly, and 8 is intended to _modify_ the outcome. So, if Concorde doesn't produce a clear-cut answer we use STV amongst the remaining options, and then we have a putative `winner'. If this winner didn't actually have enough ballots which prefer it to the default, then the default option is declared the winner. There's nothing saying we should go and restart the ballot counting with STV instead, or something. The condition for using 4 or 5 is whether there is one option which Dominates all the others, and 8 can't change the answer to that question. Ian.
