"None of the above" (NOTA), or none for short, also known as "against all" or a "scratch" vote, is a ballot option in some jurisdictions or organizations, designed to allow the voter to indicate disapproval of the candidates in a voting system. It is based on the principle that consent requires the ability to withhold consent in an election, just as they can by voting "No" on ballot questions. It must be contrasted with "abstention", in which a voter does not cast a ballot.
Entities that include "None of the Above" on ballots as standard procedure include Argentina, Belarus, Belgium, Bulgaria („Не подкрепям никого“, "I don't support anyone"), Colombia (voto en blanco), France (vote blanc, "blank vote"), Greece (λευκό, blank), India ("None of the above"), Indonesia (kotak kosong, "empty box"), Kazakhstan, Mongolia, the Netherlands, North Korea, Norway, Peru, Spain (voto en blanco, "blank vote"), Uruguay, and the U.S. state of Nevada (None of These Candidates).
