The Government justified the Emergency giving these reasons. First, in a democratic country the majority ruling party should be allowed to do things without unnecessary interference from the Opposition. Second, protests and agitations do not do anything good for the country. Third, the government did not want the Opposition to resort to any unconstitutional means to remove Indira Gandhi from power.
Fourth, Government had to take action to maintain law and order in the country. Indira Gandhi accused the Opposition saying that it prevented the government from taking welfare measures for the uplift of the masses and they wanted to remove her from power using unconstitutional means.
The CPI favoured the Emergency. At that time they argued that protests were unnecessary. They said that there were international problems threatening the unity of India. They also said that Jay Prakash Narayan was a representative of the Middle Class who objected to the reforms aimed at the welfare of the masses.These arguments were criticised. The critics pointed out that the Indian politics itself was a history of protests and agitations.
Therefore people have the right to protest against the government and its policies. None of the arrested people had committed any treason or any such grave offences. No case was registered against any of them. The threat was not to the country but to the Prime Minister and the Congress government. So there was no need for any Emergency. They felt that Indira Gandhi misused the constitutional provision for serving her personal needs.
