In regard of the voting method, in case of two candidate are tie with each other… There seem to be reference on the site about choosing what they call completion rules
Supported completion rules
CIVS currently supports five rules for Condorcet completion: Minimax-PM (the default rule), Schulze (also known as Beatpath Winner or Cloneproof Schwartz Sequential Dropping), Maximize Affirmed Majorities (MAM), a deterministic variant of MAM called CIVS Ranked Pairs, and a runoff-based Condorcet algorithm called Condorcet-IRV. The Schulze and MAM rules are described in the linked documents; Minimax-PM, CIVS Ranked Pairs and Condorcet-IRV are described below.
CIVS does not impose a completion rule; in fact, anyone viewing the results of an election can see what the results would have been with each of the rules. It is probably a good idea for the election supervisor to decide on an rule ahead of time, and include it in the election description. On the other hand, all five rules usually agree with each other, especially on the ranking of the first few candidates.
I am not sure if the above section is relevant to us, and if it is. And if yes, should the rule be chosen prior the result?
