In a first, the Hiroshima High Court ruled Monday that the results of last December's general election in Hiroshima's No. 1 and 2 districts were invalid because of significant disparities in the weight of their votes.

The ruling makes it the first court in the nation to declare an election result void as lawsuits continue to flood the system over vote-value disparities.

The election results, however, will not be invalidated immediately if the local election board appeals the ruling.
