Rule No. 49(O) in the Conduct of Election Rules 1961 says
"Elector deciding not to vote - If an elector, after his electoral roll number has been duly entered in the register of voters in Form 17 A and has put his signature or thumb impression thereon as required under sub-rule (1) of rule 49L, decided not to record his vote, a remark to this effect shall be made against the said entry in Form 17A by the presiding officer, and the signature or thumb impression of the elector shall be obtained against such remark. "
A voter can go to the polling station and tell the presiding officer that he/she does not wish to cast her/his vote. The presiding officer will make a remark that the voter does not wish to vote and take the voter's signature against his/her name in the register of voters (Form 17A). At the end of the day, the presiding officer will, in totalling the number of votes cast, also include the number of electors who refused to cast their vote. By doing so, voters make it clear to all political parties that they are not satisfied with the kind of candidates put up by them. Though they have done their duty as citizens by going to the polling station, they have not found anyone on the ballot paper who deserves their vote. This is the Protest Vote.
Say there's a candidate standing in Constituency (A).And say out of 100 people only 40 people turn to vote and out of that the Candidate recieves 30 votes. Then by rule, he's been declared as elected. But say, if out of the 100 people 70 turn to vote. and 30 people vote for the candidate and the other 40 people use section 49(0), to say i am not interested in anyof the candidate. Then if, the candidates vote(which the vote he got ie., 30 is less than the vote against him (under section 49(0) - which is 40), then by rule he would not be elected as winner and in turn he would not be able to participate in anymore further elections. And the election for Constituency (A) will be re-held with fresh candidates
