The Tokyo High Court ruled Wednesday that the 2.34 times disparity in the weight of votes seen in a single-seat constituency in Tokyo in the December House of Representatives election is unconstitutional.
The court, however, rejected the demand of plaintiffs that the election in the Tokyo No. 1 constituency be nullified, saying the Diet has taken steps to rectify the zoning of electoral districts to narrow the vote-value gap.
Presiding Judge Koichi Namba said the vote-value disparity in the December election is unconstitutional because the Diet "failed to correct (the allotment of constituencies) within a reasonable period of time" in the wake of a 2011 Supreme Court ruling.
