The events which were responsible for the downfall of the Congress Party in the 1977 elections are:

a) Compulsory sterilisation of poor in over-enthusiasm to control population.

b) Tortures and custodial deaths happened during this time.

c) Implementation of emergency for the welfare, as the reason given, but used for detention of political workers, as seen in their actions.

d) Many promises done by the government remained unfulfilled and further caused stress in the economy.
