What to do if someone cast your vote

For voting You go to the polling station and on reaching there you are informed that your vote has already been cast. So in that case you can complain about it to the presiding officer. If your complaint is proved correct, then the presiding officer can get you to cast tender vote. For this, the officials will thoroughly check your documents. If the documents are proved to be correct, then you will be allowed to cast the tender vote, but if the claim is found to be false, legal action can also be taken against you.
