Fundamental rights in India in the context of "Civil liberty"

The Constitution of India is the supreme legal document of India, and the longest written national constitution in the world. The document lays down the framework that demarcates fundamental political code, structure, procedures, powers, and duties of government institutions and sets out fundamental rights, directive principles, and the duties of citizens.

It espouses constitutional supremacy (not parliamentary supremacy found in the United Kingdom, since it was created by a constituent assembly rather than Parliament) and was adopted with a declaration in its preamble. The Indian Constitution does not contain a provision to limit the powers of the parliament to amend the constitution. However, the Supreme Court in Kesavananda Bharati v. State of Kerala held that there were certain features of the Constitution so integral to its functioning and existence that they could never be cut out of the constitution (known as the 'Basic Structure' Doctrine).

The basic structure doctrine is a common law legal doctrine that the constitution of a sovereign state has certain characteristics that cannot be erased by its legislature. The doctrine is recognised in India, Bangladesh, Pakistan, and Uganda. It was developed by the Supreme Court of India in a series of constitutional law cases in the 1960s and 1970s that culminated in Kesavananda Bharati v. State of Kerala, where the doctrine was formally adopted. Bangladesh is perhaps the only legal system in the world that recognizes this doctrine in an expressed, written and rigid constitutional manner through Article 7B of its Constitution.

In Kesavananda Bharati, Justice Hans Raj Khanna propounded that the Constitution of India contains certain basic features that cannot be altered or destroyed through amendments by the Parliament of India. Key among these "basic features", as expounded by Justice Khanna, are the fundamental rights guaranteed to individuals by the constitution. The doctrine thus forms the basis of the Supreme Court of India's power to review and strike down constitutional amendments and acts enacted by the Parliament that conflict with or seek to alter this "basic structure" of the Constitution. The basic features of the Constitution have not been explicitly defined by the Judiciary, and the determination of any particular feature as a "basic" feature is made by the Court on a case-by-case basis.

Part XVIII of the Constitution of India allows for a constitutional setup that can be proclaimed by the president of India as a state of emergency, when the consultant group perceives and warns against grave threats to the nation from internal and external sources or from financial situations of crisis. Under Article 352 of the Indian constitution, upon the advice of the cabinet of ministers, the President can overrule many provisions of the constitution, which can suspend fundamental rights to the citizens of India and acts governing devolution of powers to the states which form the federation. In the history of independent India, such a state of emergency has been declared thrice.

1. The first instance was between 26 October 1962 to 21 November 1962 during the India-China war, when "the security of India" was declared as being "threatened by external aggression".
2. The second instance was between 3 and 17 December 1971, which was originally proclaimed during the Indo-Pakistan war.
3. The third proclamation between 25 June 1975 to January 1977 was under controversial circumstances of political instability under Indira Gandhi's premiership, when emergency was declared on the basis of "internal disturbances". The proclamation immediately followed a ruling in the Allahabad High Court, that voided the Prime Minister's election from Rae Bareli in the 1971 Indian general election. She was also prohibited from contesting election for next 6 years, challenging her legitimacy to continue in her post. Indira Gandhi, instead recommended to the then president Fakhruddin Ali Ahmed to proclaim a state of emergency to strengthen her hand.

The phrase Emergency period used loosely, when referring to the political history of India, often refers to this third and the most controversial of the three occasions.
