Details of 1999 (Gyo-Tsu) 35 | Judgments of the Supreme Court
it can be said that the demarcation of constituencies by the amended
Law on Public Election was prepared in accordance with the two
criteria mentioned above. The first criterion places significance on
proportionality to the population number and requires that the ratio of
the population numbers between constituencies should be less than
1:2, although administrative division, geography, transportation etc.
are to be taken into account. The second criterion allocates one seat
to each prefecture prior to the demarcation of the boundary, and then
allocates the remaining seats to prefectures in proportion to the
population number. Thus, the second criterion acknowledges an
exception to proportionality to the population number and
presupposes a certain level of imbalance in the allocation of seats as
inevitable. Therefore, the first criterion is understood to require that
within this framework, the constituency boundaries should be
demarcated in such a way that the difference between the population
numbers per constituency is below 1:2 nationwide if possible.
Furthermore, concerning the candidates in the small constituency
election, Art.86 of the amended Law on Public Election has adopted
the system under which the political parties and other political
organisations which fulfil one of the requirements as provided by the
subparagraphs of paragraph 1 of this provision, present candidates
who are their members, and in addition, those who intend to be a
candidate. In addition, candidates may present themselves or their
supporters may also present candidates. Those political parties or
other political organisations which presented candidates (candidatepresenting political parties) may, in addition to the election campaign
conducted by the candidates, conduct an election campaign on their
own by using cars, loud speakers, documents and posters, and may
arrange newspaper advertisements and political meetings (arts. 141,
para.2, 142, para.2, 149, para.1, 161, para.1 etc., the amended Law on
Public Election) and in addition, may broadcast political views, which
is not permissible for the candidates themselves (Art.150, para.1, the
amended Law on Public Election).
The appellant argues that the small constituency system entails a
large percentage of 'dead votes', is a multiple representation system,
and is unconstitutional, since it is against the principle of people's
representation, is likely to disregard the underlying ideas of articles
55, 57, para.1, 59, para.2 etc. of the Constitution, contradicts the
principle of majority rule, and infringes upon the freedom to be a
candidate, the freedom of election and the freedom of association as
recognised by the Constitution. Furthermore, the appellant argues
that as a result of allocating one seat to each prefecture in
accordance with the criteria set by Article 3, paragraph 2 of the Law
on the Law on the Establishment of the Constituency Council, the
difference in the value of votes has exceeded 1:2. This is against the
equality principle as provided by the Constitution, and therefore, the
Provision on the Demarcation of Constituency Boundaries is null and
void by virtue of its unconstitutionality. Moreover, the fact that the
opportunity for election campaigns is not the same between
candidates who belong to the candidate presenting parties and those
who do not is a discrimination based upon creed or social status
which is prohibited by Article 14, paragraph 1 of the Constitution
(other arguments concern the proportional election system, and in the
present case where the avoiding of the small constituency election is
at issue, are in themselves, inappropriate).
2. As mentioned above, the specific determination of the scheme of
the electoral system for the members of the House of
Representatives is left to the discretion of Diet within the limitation
that all members of the Diet should represent the people. The choice
of the small constituency system as one of the methods of election of
the members of the House of Representatives shall be
unconstitutional only when the choice can be regarded as an excess
of such a discretion.
[Summary 1] The system of small constituency is accompanied by the
possibility that persons who belong to a political party which has a
high nationwide support can gain more seats than the proportion of
the votes they have won. On the other hand, opposition parties and
minority parties may gain a majority of the seats if they manage to get
