A justice system from where the justice flows, if it is not disclosed, buyers and sellers whosoever will lose cases will feel its rigged, so keeping in mind the losing party and making the justice fair, as only proper learned community members who have proper experience of both buying and selling, should be made jury.
As even if eBay comes up with a world class justice system, but adjudicators are not chosen properly it will cripple down the entire system and ruin their buyers or sellers, whosoever gets a lame experience due to unqualified jury, preceding the cases, as now it ha become more important to have class jury as majority votes are not counted,
For a seller to win the case he will require 71 percent thumping majority, this is itself very partial , as majority itslef means 51 percent, this is a new breed/ebay definition of majority.
