The Tokyo High Court on Wednesday ruled the disparity in the weight of votes in the July Upper House election was constitutional, in the last of 16 similar lawsuits filed nationwide by groups of lawyers.
The ruling was the 14th stating that the disparity of up to three times in the weight of votes between the most and least populated constituencies was constitutional. The two other rulings said the election was held in a state of unconstitutionality but rejected the plaintiffs' demands for the results of the July 21 House of Councilors election to be nullified.
The Supreme Court is expected to give a final ruling on the vote weight disparity next year.
