What election laws are made for campaigning?

Every political party and candidate gets a fair and equal chance to compete.
According to our election law, no party or candidate can:
(i) bribe or threaten the voters to vote for them only;
(ii) appeal to the voters in the name of caste or religion;
(iii) use the government resources for election campaigns;
(iv) spend more than ₹25 lakhs in a constituency for the Lok Sabha elections or ₹10 lakhs in a constituency during an assembly election.
If they do so, their election can be rejected by the court even after they have been declared elected.
