Elections

- Ballots shall list all candidates in alphabetical order. Each voter votes by placing a "1" opposite his/her first choice, "2" opposite his/her second choice, and so on, stopping at any point.
- If there are \( k \) (unspoiled) ballots and \( n \) positions to be filled,
then the
**quota**is defined to be \( q = k/n+1 \). - Each ballot is given a
**weight**, \( w \). Initially, \( w=1 \) for all ballots. - The score of a candidate is the sum of the weights of the ballots.
- If a candidate has a score \( s > q \), he/she is declared elected, except in case the number of candidates elected would exceed \( n \). In this case, there should be a runoff as in step 6 among those candidates selected on this last count. The weight of each ballot on which that candidate was next available preference is multiplied by \( (s - q)/s \) to give it a new weight.
- If no candidate has a score \( s > q \), then the candidate with lowest score, if unique, is eliminated from all ballots. A tie for lowest score is broken by a runoff scoring among the tied candidates using all ballots.
- If this fails to break the tie, one of the tied candidates is eliminated by a method to be determined by the Head.

- After step 5 has been completed for all candidates, or after step 6, the names of those candidates either elected or eliminated are struck off all ballots, and steps 4 - 6 are repeated.
- If at any time the number of available candidates is equal to the number of positions remaining unfilled, these remaining candidates are declared elected, and the process ends.
- If at any time the number of candidates whose score is
**greater**than \( k/n+1 \) is equal to the number of positions, these candidates are declared elected, and the process ends.
