disproportionality. Despite this, a spare vote is not a feature in any list PR system in use as of this date. The German Federal Constitutional Court ruled that the electoral system is not required to have such a supplementary contingent vote feature.
The term "spare vote" not only refers to the additional specification of a second preference but can also mean the electoral system working with a second preference as a whole. Not every second preference is a spare vote.
Ranked voting
Ranked voting is any voting system that uses voters' Ordinal utility, rankings of candidates to choose a single winner or multiple winners. More formally, a ranked vote system depends only on voters' total order, order of preference of the cand ...
systems differ in terms of their field of application, choice of
party lists vs. choice of individuals. In particular, the following ranking procedures should be strictly distinguished from the spare vote:

spoiler effects. Voters instead of casting their vote for a preferred party that presumably will fail to pass the electoral threshold tend to choose a less preferred party with a reliable chance of passing the electoral threshold. The security of the spare vote is intended to encourage voters to vote more honestly for their actually preferred party. On the ballot paper, the voter is given the opportunity to designate beside the first preference the spare vote, which becomes an effective vote only under the condition that the first preference fails to comply with the electoral threshold. To prevent that the spare vote falls below the electoral threshold as well, the voter should assign the spare vote to a party that is very likely to pass the electoral threshold. The spare vote continues to prevent the fragmentation of parliaments achieved by the electoral threshold.
Variants
There are different methods for evaluating the spare votes:
* One-step procedure: All votes for parties that are below the electoral threshold according to the first preferences are discarded; in their place, the spare votes for these voters are counted. This is
party list version of the
contingent vote
The contingent vote is a two-stage electoral system that elects a single representative, in which the winner receives a majority of votes. It uses ranked voting. The voter ranks the candidates in order of preference, and when the votes are f ...

(in case of just one spare vote).
* Multi-round procedure: First the party with the least number of first preferences is eliminated, and the spare votes from its voters become effective. This is repeated until only parties that are above the electoral threshold are left. The benefit compared the one-step procedure is that some political parties could pass the electoral threshold only once spare votes become effective. This is the party list equivalent of the
single transferable vote
The single transferable vote (STV) or proportional-ranked choice voting (P-RCV) is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked ballot. Voters have the option to rank candidates, and their vot ...
, which the quota being the electoral threshold.
Limiting the ranking of parties to two ranks allows a faster ballot counting procedure, where every electoral district reports only the counts of each party-pair. This procedure does not require all electoral districts to wait until the determination which parties have crossed the electoral threshold is finalized. With more than two ranks of parties, the voters rank several spare votes/parties according to their preferences. In this process, a voter's party vote is carried over until it either goes to a party that is above the electoral threshold or has passed through all of the voter's stated preferences.
The spare vote can also be used in the proportional part of
mixed electoral systems with electoral thresholds, and some mixed systems operate on the basis of an indirect spare party vote (
mixed single vote
A mixed single vote (MSV) is a type of ballot in mixed-member electoral systems, where voters cast a single vote in an election, which is used both for electing a local candidate and as a vote for a party affiliated with that candidate accordin ...
) to reuse the candidates that did not receive a direct mandate in favour of the party list they are affiliated with. The second vote under
mixed-member proportional systems may be considered a direct Spare vote for a party, but not relating to the electoral threshold, but for the case when a voters favourite local candidate does not win in their district. This is also the case for the party list preference in the
mixed ballot transferable vote (MBTV), which is may also use a ranked ballot capable of functioning a contingent party vote if combined with an electoral threshold. It is also the mixed equivalent of the spare vote (and
STV, the non-partisan equivalent of the spare vote), meaning the spare vote is used in a two-tier election, and the spare vote is used on the upper (party-list) tier only if it would be wasted on the lower (candidate-based) tier. The process is the same as under the positive vote transfer mechanism of the mixed single vote (MSV), except under MSV, voters do not get to choose their party preference, it is defined by the candidate vote.

modified d'Hondt electoral system is another preferential party system, which allows to rank parties. It is a variant of

New Zealand
The spare vote was first mentioned in NZ Academia in 2003 when a German student Claudia Winkler wrote a paper about the German electoral system.
There was a formal governmental electoral review in 2012 where changes equivalent to the spare vote were proposed by three submitters, all seemingly developed independently. The spare vote was not mentioned in the final report.
Another review in 2023 received submissions about the spare vote with positive comments about the proposal in the final report.
