Details of 1999 (Gyo-Tsu) 35 | Judgments of the Supreme Court
which some voters were given preference because of status, income,
gender etc., is apparently against the Constitution, and distorts the
principle of rule by majority which is the basis of modern democracy.
4 When the election system for the members of the Diet was
established after the Second World War, a system in which each
prefecture was made a constituency was introduced and the
discrepancy of maximum 1:2.62 was allowed. It cannot be denied that
this generated a tendency to take the equality principle in the election
of the members of both houses lightly, which still exists today. This
discrepancy which was allowed without much doubt emerged
between Miyagi and Tottori prefectures and had nothing to do with
'giving favourable consideration to depopulated areas'. However, the
fact that the existence of such a large discrepancy was allowed led to
the neglect of the problem of a totally different kind of discrepancy
emanating from the concentration of population in the cities as a
result of the subsequent large scale flow of population for many years
under the pretext of giving favourable consideration to depopulated
areas. This tendency was not limited to the election of the members
of the House of Councillors, but spread to the election of the
members of the House of Representatives. On this issue, the judiciary
continued to be tolerant, based upon the idea that it is sufficient to
decide whether the broad discretionary power granted to the Diet in
establishing the election system was exceeded or not. As a result,
accumulated judgments of the Supreme Court are understood to be
based upon the view that for the election of the members of the
House of Representatives, a maximum discrepancy of 1:3 is allowed,
and for the election of the members of the House of Councillors from
constituencies, a maximum discrepancy of 1:6 is allowed to be within
the scope of a reasonable discretionary power of the Diet.
5 Amendments to the Law on Public Election which have taken place
in recent years failed to introduce changes necessary to observe the
equality principle in a sufficient way. The amended Law on Public
Election which is at issue in the present case is of insufficient quality,
since the basic policy of the amendment is to keep the discrepancy in
constituency elections at less that 1:2 (which means attributing the
value of two votes to a single vote) despite the fact that the value of
the vote of an individual is the same as the others. Taking this as
granted, the 'plus one' system was introduced (this is really an
apparent and arbitrary manipulation of the value of votes), and had
created exceptions in exceeding 1:2 in 28 of 300 constituencies in the
light of the Census of October 1990 from the beginning. In these two
points, the Law has failed to observe the equality principle which is
the basic prerequisite to representative democracy as provided by the
Constitution and, as explained in the following, there is no reason to
justify this.
Firstly, the Constitution does not allow intentional manipulation and
differentiation in the value of votes of the electors (voters) by those
who are elected (members of the Diet). I would like to repeat that
when shaping the system of election, 'giving favourable consideration
to depopulated areas' should not accompany 'neglect of densely
populated areas'. It is a prerequisite to the enactment of laws
concerning election that the equality in the value of votes is realised
by consolidation of constituencies or increase in the number of seats
in proportion to the number of voters (the latter may be against the
requirement of slimming down ruling organisations, but such a
requirement has much less priority in quality in comparison with the
significance of the equality principle as provided by the Constitution).
Secondly, there is a view which treats prefectures in the same way as
states in a federal state and give priority to the significance of the
demarcation of constituency boundaries based upon the prefectural
system ahead of the equality principle, but this is not acceptable
either. It is obvious that Japan is not a federal state, and no provision
can be found in the Constitution which gives less significance to the
equality principle between prefectures which are basically
administrative divisions and allows the discrepancy in the value of
votes. In countries with a federal system which have a written
constitution, there is an explicit provision in the Constitution if a state
