Explanation given by SC :
Terming religion a very private relationship between man and his God, a seven-judge Bench of the Supreme Court, held that an appeal for votes during elections on the basis of religion, caste, race, community or language, even that of the electorate, will amount to a ‘corrupt practice’ and call for disqualification of the candidate.

The court was interpreting the pronoun ‘his’ used in Section 123 (3) of the Representation of the People Act, whether the word ‘his’ only meant a bar on appeals made in the name of the candidate or his rival or his agent or others in his immediate camp. Or, does the word also extend to soliciting votes on the basis of the religion, caste, community, race, language of the electorate as a whole.

As per Supreme Court, the word ‘his religion, race, caste, community or language’ appearing in section 123(3) would mean the religion, race caste or community of the candidate or the voter/ elector.

Wording of Section 123(3) Representation of the People Act: 
123. Corrupt practices.—The following shall be deemed to be corrupt practices for the purposes of this Act:—
