A group of lawyers in Hiroshima filed a lawsuit Monday seeking nullification of the general election, saying the vote-value disparity among current single-seat districts is unconstitutional.
The lawyers claim in their suit in the Hiroshima High Court that there is an inequality in the value of votes because there are too many or too few lawmakers in 31 prefectures, as the allocation of Diet seats is not proportionate to population distribution.
"Voting is a basic and important right in terms of suffrage. It is negligence on the part of the Diet that (districts) do not correspond to changes in the distribution of population," said Tetsuya Kanao, one of the lawyers.
Lawyer groups are planning to file about 20 similar lawsuits with other high courts.
