The  constitution of a country, in simple terms, is a collection of the  legal rules providing the frame work for the Government  of the country.  The strength and stability of a constitution depends largely on its  ability to sustain a healthy and peaceful social system and when  occasion demands, facilitate the peaceful transformation  of its  economic and social order. Its basic objective is to establish a  democratic, socialist, secular republic wish a view to securing justice  liberty, equality and fraternity to all its citizens.
The following are the outstanding features of the Indian Constitution.
1. A written constitution:
The  Republic of India has a written and enacted constitution; it contained  409 Articles, twelve schedules and three appendices. In its present form  it covers 254 octavo pages. “Like the constitution of the United States  of America, Canada and France, India too has a written constitution,  though it differs from those documents in many respects.”
2. The Longest Known Constitutions:
The  constitution of India has the distinction of being the most lengthy and  detailed constitutional document the world has so far produced. The  original constitution contained as many as 395 Articles and 8 schedules.  Even after the repeal of several provision of it still contains 409  articles and 12 schedules.
Ti  has been the endeavor of the framers of the constitution to provide for  the solution of all the problems of administration and governance of  the country. Even those matters which are subject of conventions in  other countries have been pt down in black and white. Thus, whole the  U.S. Constitution originally compresses only 7 Articles, the Australian  128 Articles, the Canadian 147 Articles; the constitution o India in  original form consists of 395 Articles and 8 schedules. As a result of  some amendments made since then, some new Articles have been added and  some old ones repealed.
3. Popular Sovereignty:
The  constitution proclaims the sovereignty of the people in its opening  words. The preamble begins with the words, “we the people of India,  having solemnly resolved to constitute India into a sovereign socialist  secular democratic Republic”. The idea is reaffirmed in several places  in the constitution, particularly in the chapter dealing with elections.  Article 326 declares that ‘the election to the House of people and to  the Legislative Assembly of every state shall be on the basis of adult  suffrage”.
As  a result, Government at the centre and in the states derives their  authority from the people who choose their representatives for  parliament and the state legislatures of regular intervals. Further,  those who wield the executive power of the government are responsible  for the legislature and through them to the people. Thus, in the affairs  of the state, it is the will of the people that prevails ultimately and  this is the principle of popular sovereignty.
4. Sovereign Democratic Republic:
The  preamble of the constitution declares India to be a sovereign  democratic Republic it is sovereign since India has emerged as a  completely Independent state. The word ‘Democratic’ signifies that the  real power emanates from the people. The constitution introduces the  country the right to elect their representatives for the union  Parliament and state legislatures at the time of periodical elections to  be held every five years. The world ‘Republic’ is used to denote that  the state is headed not by a permanent head like the queen of Britain  but by a President indirectly elected by the people.
5. Both Rigid and Flexible:
The  Indian constitution is partly rigid and partly flexible. The procedure  said down by the constitution for its amendment is neither very easy, as  in England, nor very rigid as in the United States.
The  constitution of India strikes a golden mean thereby avoiding the  extreme flexibility of the English constitution and the extreme rigidity  of the American constitution.
It  is only the amendment of few of the provisions of the constitution that  requires notification by the state legislatures and even then  ratification by only ½ of them would suffice.
The  rest of the constitutions may be amended by the special majority of the  union Parliament i.e. a majority of not less than 2/3 of the members of  each. House present and voting which again must be a majority of the  total membership of the House.
The  very fact that within a period of 47 years the constitution had been  amended 76 times proves that the constitution is flexible.
6. Cabinet Government:
The  constitution establishes cabinet type of Government both of the centre  and the units. The most distinctive feature of a Cabinet system of  government is the complete and continuous responsibility of the  executive to the legislature. The cabinet is composed of the Prime  Minister, who is the chief of the executive and his senior colleagues  who share the responsibility with him for the formulation and execution  of the policies of the Government.
Under  the Cabinet system the Head of the cabinet occupies a position of great  dignity, but practically all authority nominally vested in him is  exercised by the cabinet. The unitary and collective responsibility of  the cabinet is composed of the Prime Minister, who is the keystone of  the cabinet arch. The real merit of cabinet system is that the executive  being responsible to the legislature is always being watched.
7. Secular State:
A  secular state has negative and positive aspects. Negatively, it is the  antithesis of a communal or theocratic state which officially identified  it self with a particular religion. In a secular state, on the other  hand there is no official or state religion. In its positive aspects a  secular state treats all its citizens alike and gives them equal  opportunities. The state has no official religion. No discrimination can  be made on the basis of religion, faith, caste, color and sex. Every  citizen is equal before law.
8. A federal system with unitary Bias:
The  most remarkable achievement of the Indian constitution is to confer  upon a federal system the strength of a unitary Government Though  normally the system of government is federal the constitution enables  the federation to transform into unitary state.
The  constitution of India establishes a federal polity which has been  created by dividing the country into states and allocating them  functions as specified in the constitution. India has a written  constitution which is rigid to a large extent. There is a dual polity  and division of powers between the centre and the states.
The  Indian constitution has a unitary bias for instance, after distributing  the legislative powers in three lists residual subjects are left with  the union. Even in matters in the concurrent list, the union Government  has the final say Parliament in India has a might to change the  boundaries of the state. The centre can at any time declare emergency in  the states. The Governors are appointed by the President.
9. Universal Franchise Without communal Representation:
The  adoption of universal adult suffrage, without any qualification either  of sex, property, taxation or the like, is a bold experiment in India,  having regard to the vast extent of the country and its population, with  on over whelming illiteracy. The suffrage in India, it should be noted  is wider than that in England or the United States.
10. Compromise between Judicial Review and Parliamentary sovereignty:
Parliament  in India is not as supreme as the British parliament. At the the same  time judiciary in India is not as supreme as in the United States of  America which recognize no limit on the scope of Judicial Review. The  Indian constitution wonderfully adopts the via media between the  American system of judicial supremacy and the English principle of  Parliamentary Supremacy, by endowing the judiciary with the power of  declaring a law as unconstitutional if it is beyond the competence of  the legislature according to the distribution of powers provided by the  constitution, or if it is in contravention of the fundamental rights  guaranteed by the constitution, but at the same time depriving the  judiciary of any power of ‘judicial review’ of the wisdom of legislative  policy. Thus, it has avoided impressions like due process and made  fundamental rights such as that of livery and property subject to  regulation by the legislature.
11. Independence of Judiciary
The  framers of the constitution were aware that democratic freedoms were  meaningless in the absence of an independent machinery to safeguard  them. No subordinate or agent of the Government could be trusted to be  just and impartial in judging the merits of a conflict in which the  Government itself was a party. Similarly, a judiciary subordinates  either to the centre or the states could not be trusted as an impartial  arbiter of conflicts and controversies between the centre and the  states. These were the compelling reasons for the creation of an  independent judiciary as an integral part of the constitution and for  the adoption of judicial independent as a basic principle of the  constitution.
12. Fundamental Rights:
Like  the constitution of the United States of America, the constitution of  India also includes a separate chapter guaranteeing fundamental Rights  to all the citizens. These rights are justiciable and inviolable. They  are binding on the legislature as well as on the executive. If any of  the rights is violated, a citizen has the right to seek the protection  of the judiciary. Act of the legislature or odder of the executive can  be declared rule and void if it violates any of the fundamental rights  guaranteed to the citizens by the constitutions.
13 Fundamental Duties:
The  42nd Amendment Act introduced ‘Fundamental duties’ to circumscribe the  fundamental rights even thought the duties as such cannot be judicially  enforced. The incorporation of fundamental duties in the constitution  was thus an attempt to balance the individual’s civic freedoms with has  civic obligations and thus to fill a serious gap in the constitution.
14. Directive principles of state policy:
This  feature has been taken from the Irish constitution. The philosophy  behind the Directive principles is that the state and every one of the  agencies are commanded to follow certain fundamental principles while  they frame their policies regarding the various fields of state  activity. These principles on the other hand, are assurances to the  people as to what they can expect from the state and on the other are  directives to the Government central and state to establish and maintain  a new “social order in which justice, social economic ad political,  shall inform all the institution of national life.”
Criticism of Indian Constitution -
The  constitution of India is remarkable for many outstanding features which  will distinguish it from other constitutions, even though there were  members in the constituent Assembly who criticized the constitution  which was going to be adopted as a slavish imitation of the west or not  suited to the genius of the people. The most criticism is following:
First: The  constitution of India is being criticized on the ground that it is the  most lengthy and detailed constitutional document the world has so far  produced.
Second: The  constitution of India is called as the carbon copy of the Act of 1935.  The fathers of the constitution have borrowed a large number of  provisions from the Act of 1935 and made them part of the new  constitution.
Third: One  of the frequent criticism of the constitution was that was a lawyer’s  paradise. It is true that the constitution is a complex document. The  language in which it was drafted is that which is familiar only in  courts of law.
Fourth: The  constitution has been criticized by a small but vocal section on the  ground that it is un-Gandhian. The constitution did not embody the  principles for which Mahatma Gandhi stood or the ideology of the Indian  National Congress.
Fifth: It  is said that the Indian constitution is a bag of borrowings or is a  more paper and scissors work. Parliamentary form of government is  borrowed from the British constitution while federalism and judicial  review is borrowed from the U.S. constitution.
Sixth: According  to some critics, the centre has been made to strong. There is too much  centralization and that eh states have been reduced to municipalities.
Seventh: The  new constitution is called as un_Indian anti-Indian that no part of the  constitution represents the ancient polity of India, its genius and the  sprit of its hallowed and glorious traditions.
In spite of the above weakness the Indian Constitution occupied an important place in India.
