日本国憲法 - e-Gov法令検索
人民ハ其ノ政府及皇位ノ終局的決定者ナリ彼等ハ其ノ公務員ヲ選定及罷免スル不可譲ノ権利ヲ有ス
一切ノ公務員ハ全社会ノ奴僕ニシテ如何ナル団体ノ奴僕ニモアラス
有ラユル選挙ニ於テ投票ノ秘密ハ不可侵ニ保タルヘシ選挙人ハ其ノ選択ニ関シ公的ニモ私的ニモ責ヲ問ハルルコト無カルヘシ
The people are the ultimate arbiters of their government and of the Imperial Throne. They have the inalienable right to choose their public officials and to dismiss them.
All public officials are servants of the whole community and not of any special groups.
In all elections, secrecy of the ballot shall be kept inviolate, nor shall any voter be answerable, publicly or privately, for the choice he has made.
