{{see-wp}}SNTV is [[Choose-one FPTP voting|choose-one FPTP voting]] applied to the multi-winner context. It is a semi-proportional method. ▼
▲
SNTV passes a very weak form of Hagenbach-Bischoff-[[PSC]] (and Droop-PSC): if a group of voters of at least k HB quotas evenly distribute their votes between k candidates such that each candidate has at least one HB quota, then they can guarantee all of those
If the k candidates instead each have a Droop quota, they are guaranteed to win, rather than only being guaranteed to either tie or win.
By analog to [[Duverger's law]], SNTV in n-seat districts tends to produce (n+1)-party rule.<ref>{{cite journal|title=Structure and Behaviour: Extending Duverger's Law to the Japanese Case|journal=British Journal of Political Science|first1=Steven R.|last1=Reed|volume=20|issue=3|year=1990|pages=335–356|jstor=193914|doi=10.1017/S0007123400005871}}</ref>
== Notes ==
SNTV can be combined with [[Party List]] by allowing each voter to give their vote to a party or to a candidate; the parties can each be allocated a certain number of seats, while independents can still win on their own. Note that this is possible even in the single-winner case (where SNTV is equivalent to the common choose-one [[FPTP]] voting method) to ensure that a plurality or majority elect someone from their preferred group of candidates, if there are many candidates in that group splitting the vote. The cast votes can also themselves be used to decide who within the Party List should win i.e. the candidates on the list with the most votes can be prioritized.
