Article 324 cannot override election law: voting by machine was unauthorised, and no estoppel barred the challenge.

Article 324 gives the Election Commission residual supervisory power over elections, but only in gaps left by valid parliamentary legislation and rules; it cannot introduce voting by machine where the Representation of the People Act, 1951 and the Conduct of Election Rules, 1961 already govern the method of voting. The expression "ballot" in Section 59 and Rule 49 was treated as referring to voting by ballot paper, not by machine. There is no estoppel against statute, so participation or silence cannot validate an unauthorised voting method. The result based on the mechanical process could not stand, and a repoll was required in the affected polling stations.

Issues: (i) Whether the Election Commission's power under Article 324 of the Constitution of India authorised it to introduce voting by machine in the teeth of the Representation of the People Act, 1951 and the Conduct of Election Rules, 1961; (ii) Whether the expression "ballot" in Section 59 of the Representation of the People Act, 1951 and Rule 49 of the Conduct of Election Rules, 1961 included voting by machine; (iii) Whether the appellant was estopped from challenging the use of voting machines.

Issue (i): Whether the Election Commission's power under Article 324 of the Constitution of India authorised it to introduce voting by machine in the teeth of the Representation of the People Act, 1951 and the Conduct of Election Rules, 1961.

Analysis: Article 324 was held to be a reservoir of executive power for superintendence, direction and control of elections, but only in areas left unoccupied by valid parliamentary legislation or rules. The constitutional scheme in Part XV required Article 324 to be read harmoniously with Articles 327 to 329. Where Parliament had enacted law and the rule-making authority had prescribed the method of voting, the Commission could not innovate a contrary method under the guise of electoral control. The Commission's authority was held to supplement, not supplant, the statutory regime.

Conclusion: The Commission had no jurisdiction to direct voting by machine where the Act and Rules governed the manner of voting.

Issue (ii): Whether the expression "ballot" in Section 59 of the Representation of the People Act, 1951 and Rule 49 of the Conduct of Election Rules, 1961 included voting by machine.

Analysis: The statutory scheme, including the provisions dealing with ballot paper, counterfoil, recording of votes and return of ballot papers, was treated as inconsistent with mechanical voting. The Court held that the word "ballot" in its ordinary and popular sense referred to voting by ballot paper and not by voting machine, especially since the statutory regime in force did not contemplate such a device.

Conclusion: Voting by machine was not authorised by Section 59 of the Representation of the People Act, 1951 or Rule 49 of the Conduct of Election Rules, 1961.

Issue (iii): Whether the appellant was estopped from challenging the use of voting machines.

Analysis: There can be no estoppel against a statute. Participation or silence could not validate a mode of voting that was not authorised by law.

Conclusion: The challenge was not barred by estoppel.

Final Conclusion: The election result based on votes cast through the unauthorised mechanical process could not be sustained, and a repoll was required in the affected polling stations while the lawful votes elsewhere remained undisturbed.

Ratio Decidendi: Article 324 confers only residual executive authority to regulate elections in areas not covered by valid legislation or rules, and the Election Commission cannot override the statutory scheme by introducing a method of voting inconsistent with the governing Act and Rules.
