Why we need a constitution (in detail)

What is a constitution ? What are its functions ? What role does it perform for a society ? How does a constitution relate to our daily existence ? Just go through these basics. Answering these questions is not as difficult as you might think.

Constitution allows coordination and assurance

Imagine yourself to be a member of a reasonably large group. Further imagine that this group has the following characteristics. The members of this group are diverse in various ways. They have different religious allegiances: some are Hindus, some are Muslims, some Christians and some perhaps profess no religion at all. They are also varied in many different respects: they pursue different professions, have different abilities, have different hobbies, different tastes in everything from films to books. Some are rich and some are poor. Some are old, some young. 
Imagine further that members of this group are likely to have disputes over various aspects of life: How much property should one be allowed to own? Should it be compulsory that every child be sent to school or should the parents be allowed to decide? How much should this group spend on its safety and security? Or should it build more parks instead? Should the group be allowed to discriminate against some of its members? Every question will elicit a variety of answers from different people. 
But, for all their diversity, this group has to live together. They are dependent upon each other in various ways. They require the cooperation of each other. What will enable the group to live together peacefully?

One may say that perhaps members of this group can live together if they can agree on some basic rules. Why will the group need certain basic rules? Think of what would happen in the absence of some basic rules. Every individual would be insecure simply because they would not know what members of this group could do to each other, who could claim rights over what. Any group will need some basic rules that are publicly promulgated and known to all members of that group to achieve a minimal degree of coordination. 
But these rules must not only be known, they must also be enforceable. If citizens have no assurance that others will follow these rules, they will themselves have no reason to follow these rules. Saying that the rules are legally enforceable gives an assurance to everybody that others will follow these, for if they do not do so, they will be punished. 
So The first function of a constitution is to provide a set of basic rules that allow for minimal coordination amongst members of a society.

Specification of decision making powers 

A constitution is a body of fundamental principles according to which a state is constituted or governed. But what should these fundamental rules be? And what makes them fundamental? Well, the first question you will have to decide is who gets to decide what the laws governing the society should be? You may want rule X, but others may want rule Y. How do we decide whose rules or preferences should govern us? You may think the rules you want everyone to live by are the best; but others think that their rules are the best. How do we resolve this dispute? So even before you decide what rules should govern this group you have to decide: Who gets to decide? The constitution has to provide an answer to this question. It specifies the basic allocation of power in a society. It decides who gets to decide what the laws will be. 
In principle, this question, who gets to decide, can be answered in many ways: in a monarchical constitution, a monarch decides; in some constitutions like the old Soviet Union, one single party was given the power to decide. But in democratic constitutions, broadly speaking, the people get to decide. But this matter is not so simple. Because even if you answer that the people should decide, it will not answer the question: how should the people decide? For something to be law, should everyone agree to it? Should the people directly vote on each matter as the ancient Greeks did? Or should the people express their preferences by electing representatives? But if the people act through their representatives, how should these representatives be elected? How many should there be?
So The second function of a constitution is to specify who has the power to make decisions in a society. It decides how the government will be constituted.

Limitations on the powers of government 

Constitutions limit the power of government in many ways. The most common way of limiting the power of government is to specify certain fundamental rights that all of us possess as citizens and which no government can ever be allowed to violate. The exact content and interpretation of these rights varies from constitution to constitution. But most constitutions will protect a basic cluster of rights. Citizens will be protected from being arrested arbitrarily and for no reason. This is one basic limitation upon the power of government. Citizens will normally have the right to some basic liberties: to freedom of speech, freedom of conscience, freedom of association, freedom to conduct a trade or business etc. In practice, these rights can be limited during times of national emergency and the constitution specifies the circumstances under which these rights may be withdrawn.
So the third function of a constitution is to set some limits on what a government can impose on its citizens. These limits are fundamental in the sense that government may never trespass them.

Aspirations and goals of a society

Most of the older constitutions limited themselves largely to allocating decision-making power and setting some limits to government power. But many twentieth century constitutions, of which the Indian Constitution is the finest example, also provide an enabling framework for the government to do certain positive things, to express the aspirations and goals of society. The Indian Constitution was particularly innovative in this respect. Societies with deep entrenched inequalities of various kinds, will not only have to set limits on the power of government, they will also have to enable and empower the government to take positive measures to overcome forms of inequality or deprivation.
So The fourth function of a constitution is to enable the government to fulfil the aspirations of a society and create conditions for a just society.

Food for thought
  1. The constitution makers have to address themselves to very different aspirations. Here is Nehru trying to balance between different visions and ideologies. Can you identify what these different groups stand for? Who do you think prevailed in this balancing act?
  2. The writing of the new Iraqi constitution after the collapse of Saddam Hussein's regime saw a lot of conflict between different ethnic groups in the country. What do these different people stand for? Compare the conflict depicted here with that depicted in earlier cartoons for the European Union and India.
  3. Countries of the European Union tried to create a European constitution. The attempt failed. Here is a cartoonist’s impression of this attempt. Does this always happen in any constitution making?
