Another court on Tuesday ruled the outcome of the December general election unconstitutional and invalid in a specific district, citing a significant disparity in the weight of votes.

The Okayama branch of the Hiroshima High Court decided to void the Lower House election outcome in the Okayama No. 2 district, a day after the high court nullified the election results for Hiroshima's No. 1 and 2 districts in an unprecedented ruling.

Presiding Judge Noriyoshi Katano of the Okayama branch accused the Diet of neglecting to address vote disparity issues and disregarding the nation's legal system.
