Charan Lal Sahu v. Giani Zail Singh, (1984) 1 SCC 390 must clearly govern the present case.
It is settled, where a person has no interest at all, or no sufficient interest to support a legal claim or action, he will have no locus standi to sue. The entitlement to sue or locus standi is an integral part of cause of action.
The Representation of the People Act, 1951 allows only an elector or candidate to maintain an election petition. Impliedly, it bars any other person from filing an election petition. The present election petition has been rightly nipped in the bud.
