ZERO PROJECT's mission is working for a world with zero barriers. In 2013 Japan's Election Law persons under adult guardianship were deprived of their right to vote.
Ms Takumi Nagoya, the plaintiff, a 50-year-old woman with Down syndrome, sued the government in February 2011.
The Tokyo District Court judged on 14 March 2013 the relevant article as unconstitutional.
As a result, the Parliament swiftly adjusted the legislation.
To the award ceremony, the following three persons attended:

  • Ms Hitomi Sugiura, the lead lawyer
  • Mr Nagoya, Ms Nagoya's father, a former director of Japan Down syndrome Society
  • Dr Nagase Osamu, a Council Member of Inclusion International, Special Member of International Activity Committee of Inclusion Japan and Special Visiting Professor at Ritsumeikan University
