Filling Casual Vacancies after a PR Election

 

Ensuring Voters Directly Elect All the Representatives:

The PRSA recommends that the important principle of direct election by the electors of all the representatives, as also specified in Sections 7 and 24 of the Australian Constitution for general and periodic elections, but unfortunately not for filling Senate casual vacancies, whose filling is determined by Section 15, be maintained in the filling of casual vacancies by a prescribed re-examination of the ballots cast at the election at which the vacating representatives were elected. It is necessary for this that either the ballot-papers (manual count) or the ballot files (computer count) be securely retained until the next general or periodic election, and that expressions of interest in filling the vacancy, and serving for the remainder of the vacating representative's term, be invited from all the candidates at the last election that were unelected and still remain eligible for election. The candidates that accept that invitation and meet those criteria are termed continuing candidates. Two approaches exist for conducting that re-examination.

 

  • Political Elections where Party Balance of Power is Significant:

The approach recommended here by the PRSA is the countback approach as prescribed for House of Assembly and muncipal council elections in Tasmania, any PR municipal council elections in Victoria, and Legislative Assembly elections in the Australian Capital Territory. That approach always results in the election of a candidate of the same political party as the vacating candidate, unless the voters have specifically voted otherwise. In a countback only the quota of votes that elected the vacating representative is examined. Where the re-examination shows a continuing candidate that gained, at that election, an absolute majority of the next available preference votes after the preferences of the vacating candidate at that election, that continuing candidate is declared elected to fill that vacancy.

If no candidate gains an absolute majority then, the candidate with the fewest next available preference votes is declared to be excluded, and that candidate's next available preference votes within the quota of votes being re-examined are transferred to the remaining continuing candidates. If a continuing candidate then gains an absolute majority of next available preference votes, that candidate is declared to be elected, but if no candidate does, the process of excluding the continuing candidate with the lowest total of next available preference votes and transferring that candidate's votes continues, and is repeated for successive continuing candidates until one such candidate gains an absolute majority of next available preference votes.

Countback is less time-consuming for manual counts of ballot-papers, as only one quota of votes is involved; and it works best for maintaining the complexion and balance in the spectrum of views reflected at the relevant original election. The countback scrutiny that first elected Dr Bob Brown of the Greens Party to the Tasmanian House of Assembly to fill a seat vacated by an Australian Democrat MHA was an exception to the normal outcome where a candidate of the same party is elected, but it shows how countback faithfully reflects the choices made by the voters at the election at which the vacating candidate was elected.

  • Elections where Party Balance of Power is less Significant:

The alternative approach, which is more time-consuming for manual counts, but is simple and straightforward for computer-based counts, is that all the votes cast at the election are examined, as is prescribed for Legislative Council elections in Western Australia, and for elections to the General Synod of the Church of England in the UK since the 1920s. The only preferences that are passed over are those for the vacating candidate. A "savings provision" in the prescription for this approach states that any non-vacating already-elected candidate cannot be displaced by this recount. For manual counts this full recount approach is more time-consuming than countback by a factor similar to the number of candidates, and is less likely to maintain the complexion and balance in the spectrum of views mentioned above.

However, if an organization uses for the original election the economical computer-based service PRSAV-T Inc. offers, and it authorizes PRSAV-T Inc. to retain the computer files involved, until the next general or periodic election, PRSAV-T Inc. will conduct a count to fill casual vacancies during that time
for no charge provided that the full recount method is sought to be used, as the computer program readily enables that to be done. The result, with full details, can be provided by return email. The program that PRSAV-T Inc. uses does not yet provide for the countback system to be used. Filling of casual vacancies by countback must be done by PRSAV-T Inc. manual counting at the hourly rates stated elsewhere here.

Very little time is taken where a vacating candidate had a quota or more of first preference votes, but more time is required where that is not the case, and the pattern of the vacating member's support is more fragmented. The full recount approach gives an extremely quick, impartial result that is decided by the voters at the same poll as filled the seat that has been vacated. The organization’s electoral rules can be altered to provide for such recounts by whichever method is prescribed, i.e. either a referendum of electors or a resolution of the governing body, with a default proviso that the governing body should fill the vacancy if a recount is not practicable for lack of consenting candidates, or other valid reason.
