In the 2000 Presidential fiasco recount, each re-count station had a Democrat and Republican "observer" who could challenge a ballot, which was then put aside, and reviewed by a panel of judges for the final decision.  In theory, this is fine.  Problem is this: if the current ballots in question are all/mostly fraudulent to begin with (which is why they may be outside the original tally), then these ballots will only help the fraud supported candidates in the end, in this case the Dems.
