The Election Commission of India ordered on 13 October 2013 the Chief Electoral Officers of all States and Union territories to provide for None of the Above (NOTA) option in electronic voting machines (EVMs) and ballot papers.

The None of the Above option will be provided at the bottom of the panel on the EVMs or as the last row in the ballot paper after all the candidates have been listed with their respective symbols in the same language used to list the candidates. Likewise, the contours of the NOTA panel will be identical to that given to each candidate.

In constituencies contesting more than 16 candidates in the fray, an extra EVM will be attached to the first balloting unit for the NOTA option as the EVMs currently in use can accommodate only 16 rows.
The NOTA votes will be counted and indicated in the final result chart.

The Election Commission of India clarified that in the extreme case of the NOTA option polling more votes than any of the candidates in the fray, the candidate who gets the maximum number of votes will be declared the winner.

The NOTA option was made mandatory by the Supreme Court of India on 27 September 2013 and gave the direction to the Election Commission of India to provide none of the above options at the end of the list of candidates contesting an election in a constituency.
