Legal teams in Japan will file lawsuits across the country on Monday seeking the nullification of the results of an upper house election, which saw the ruling Liberal Democratic Party-led (LDP) coalition win a landslide victory.
Japan's Supreme Court ruled Wednesday that the 2013 Upper House vote was held "in a state of unconstitutionality"due to the disparity in the weight of individual votes across different constituencies.
Two more high courts in Japan ruled Monday that July's upper house election was "in a state of unconstitutionality" due to voter weight disparities, an issue that has plagued the nation's electoral system.
