7 Primary Sources of Constitution

1. Conventions: Conventions are agreements based on common consents. They are constitutional morality, which must be observed, though not necessary backed by the law, for the proper functioning of the constitution.

Conventions follow such moral principles like: one defected in an election must leave his post for the winners a member of the executives indicated in a crime, corrupt conducts or abuse of his office must resign; members of national assembly should form a quorum before they could seat, convene meetings and pass bills; president must assent to all bills duly passed by the National Assembly even if he disapproves them; a government official implicated in currupt practice must design; unpopular government must either resign or ask for dissolution.

These are codes of conduct with which government functions. They are codes of conduct with which must be followed for the proper functioning of constitution.

In other words, conventions are binding practices, which are forms of political behaviors regarded as obligatory. A breach of convention may jeopardize the government.

They are “Rules of political practices which are regarded as binding on those whom they apply but which are not laws as they are not enforced by the court or Houses of Parliament.”

The observance of conventions nevertheless helps in the development of any constitution. It is in most cases more functional in countries with unwritten constitution. Most importantly conventions are adopted in international organizations.

Each village or town in Nigeria has certain customary practices that the constitution of the country observes. If the customary practice or the traditions are generally accepted, the constitution must take notice of them.

Nigerian constitution integrates those good custom and traditions which form part of the people’s life. A custom may be adopted as part of the law guiding a particular set of circumstances if it can be judicial noticed or can be proved to exist by evidence (see S. 16 (1) of Evidence Act 2011).

A good custom must protect, preserve and promote Nigerian culture that is not contradictory to Nigeria’s fundamental objectives. A good custom must not be repugnant to natural justice, equity and good conscience.

7. Academic research and opinions: These are opinions of academicians who are well embraced with the value system of a nation. They are one of the major sources of constitution because they conduct thorough research and analysis on certain issues which may be worthy of being part of the constitution of a nation.

Take for example, when there are some constitutional provisions that are unfair or illogical when put into effect, the opinions of academic writers through publications and media can cause the government to look into such provisions again. And sometimes, amendments are made to the provisions so as to resolve the problem.
