None of the Above (NOTA), 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 all 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.
Entities that include "None of the Above" on ballots as standard procedure include India ("None of the above"), Greece (λευκό, white, but unrelated to a political party of the similarly sounding name-however it is symbolic only), the U.S. state of Nevada (None of These Candidates), Ukraine (Проти всіх), Spain (voto en blanco), and Colombia (voto en blanco). Russia had such an option on its ballots (Против всех) until it was abolished in 2006.Bangladesh introduced this option (না ভোট) in 2008. Pakistan introduced this option on ballot papers for the 2013 Pakistan elections, but the Election Commission of Pakistan later rejected it.
