today we're going to talk about something really important, recently we discussed the approaches to legal reasoning. Now, we're driving into a new topic– the Constitution under legal system as a course. If you're studying law or just interested in how our legal system works, you need to get a solid grasp of what the constitution actually is. We'll look at the different types of constitutions out there, what makes a good one, and how it all works in Nigeria specifically.
Introduction
Here's the thing – the constitution isn't just some boring legal document gathering dust somewhere. It's basically the soul of any country's political system. Think of it as the rulebook that tells everyone how the game should be played. It sets up how the government should work, creates the institutions we see today, and spells out what rights people have and what responsibilities the government has toward its citizens. Without it, you'd have chaos because there'd be no agreed-upon rules for how things should run.
In Nigeria, the constitution sits right at the center of everything legal. We call it the grundnorm, which is just a fancy German word meaning "basic norm." What this means is that every other law in the country gets its power and validity from the constitution. If you want to understand Nigerian law properly, you really need to understand the constitution first. It influences how laws are created, how judges make decisions, and how people's rights are protected. Everything flows from it.

What We're Going to Cover
By the time we finish going through this, you should be able to do a few things:
> First, you should be able to explain what a constitution actually is in simple terms.
> Second, you'll know about the different types of constitutions that exist around the world.
> Third, you'll understand what makes a constitution good versus one that's not so great.
> Fourth, you'll know where Nigerian constitutional law comes from – not just the constitution itself, but other sources too.
> And finally, you'll get why all this matters in real life, not just in theory.
Different Types of Constitutions
Constitutions aren't all the same. Different countries do things differently, and that's actually pretty interesting when you start looking at it. Let's break down the main categories.
Written vs Unwritten Constitutions
A written constitution is pretty much what it sounds like. It's when a country puts all its constitutional rules into one document or a set of documents that you can actually point to and read. Nigeria has this type. Our 1999 Constitution (which has been amended several times since then) is a physical document you can hold in your hand. The United States has one too – that famous document they keep under glass in Washington DC. India also operates with a written constitution, and theirs is actually one of the longest in the world.
Now, an unwritten constitution is a bit trickier to understand. It doesn't mean there's nothing written down at all. What it means is that there's no single document called "The Constitution." Instead, the constitutional rules come from all sorts of places – old laws passed by parliament, court decisions made over hundreds of years, traditions that everyone follows, and customs that have become established practice. The United Kingdom is the classic example here. They've been around for so long that their constitution is basically scattered across centuries of history, court cases, and parliamentary acts. It's all there, just not in one neat package.
Rigid vs Flexible Constitutions
This distinction is about how easy or hard it is to change the constitution. A rigid constitution is one that you can't just change whenever you feel like it. You need special procedures, usually involving more steps than passing a regular law. Nigeria's constitution is rigid. Section 9 of our 1999 Constitution lays out this complicated process where you need approval from both the federal legislature and a certain number of state legislatures. It's deliberately made difficult because the constitution is supposed to be stable and not change with every political wind that blows.
A flexible constitution, on the other hand, can be changed pretty easily. Often you can amend it the same way you'd pass any other law. The British constitution works this way. Parliament can change constitutional rules just by passing a new law. There's no special procedure required. This has advantages and disadvantages. The advantage is that the constitution can adapt quickly when society changes. The disadvantage is that fundamental rights and structures might not be as protected as they would be in a rigid system.
Federal vs Unitary Constitutions
This is about how power is distributed in a country. A federal constitution divides power between the central government and regional governments. Nigeria operates this way. We have a federal government in Abuja, and then we have 36 state governments, each with its own powers. The constitution specifically says which powers belong to the federal government, which belong to states, and which are shared. The United States works the same way, with Washington DC handling some things and the 50 states handling others. Germany also has this federal structure.

A unitary constitution puts all the real power in one central government. Regional or local governments might exist, but they basically do whatever the central government allows them to do. France works this way. So does the United Kingdom, although they've been moving toward giving more power to Scotland, Wales, and Northern Ireland in recent years. In a unitary system, the central government could theoretically abolish local governments if it wanted to. In a federal system, that's not possible because the regional governments have constitutionally protected powers.
What Makes a Constitution Good?
Not all constitutions are created equal. Some work really well, and others cause more problems than they solve. Let's talk about what characteristics a good constitution should have.
Supremacy
This is huge. The constitution needs to be the highest law in the land. Everything else – every other law, every government action, every court decision – has to be consistent with the constitution. If something contradicts the constitution, it's invalid. Section 1(3) of Nigeria's 1999 Constitution makes this crystal clear. It says that if any law is inconsistent with the constitution, that law is null and void to the extent of the inconsistency. This supremacy is what gives the constitution its power and authority.
Separation of Powers
A good constitution doesn't put all power in one place. It divides governmental power among different branches – typically the legislature (which makes laws), the executive (which enforces laws), and the judiciary (which interprets laws). Each branch has its own responsibilities, and each can check the others to prevent abuse of power. This system of checks and balances is crucial for preventing tyranny and protecting citizens' rights.
Protection of Fundamental Rights
This is probably the most important feature for ordinary people. A good constitution guarantees basic human rights and freedoms. In Nigeria, Chapter IV of our constitution lays out fundamental rights like the right to life, the right to personal liberty, freedom of expression, freedom of movement, and the right to fair hearing, among others. These aren't just nice words on paper – they're legally enforceable rights that citizens can go to court to defend.

Rule of Law
This principle says that everyone is subject to the law – nobody is above it. The government has to follow the law just like everyone else. The president can't just do whatever he wants. Government officials can't violate your rights without consequences. The police can't arrest you without following proper procedures. Everyone plays by the same rules, and those rules are known and predictable.
Stability and Predictability
A constitution should provide a stable framework that doesn't change every few years. People need to know what the rules are and trust that those rules will still be in place tomorrow. Businesses need stability to plan investments. Citizens need predictability to understand their rights and obligations. A constitution that's constantly changing or being ignored creates uncertainty and undermines the entire legal system.
Amendability
Now, this might seem to contradict what I just said about stability, but hear me out. While a constitution should be stable, it also needs to be capable of change when necessary. Society evolves. New challenges emerge. Technologies develop that the framers of the constitution couldn't have imagined. A good constitution provides a mechanism for amendment – not so easy that it changes all the time, but not so difficult that it becomes outdated and irrelevant. It's a balance.
Where Does Nigerian Constitutional Law Come From?
When we talk about constitutional law in Nigeria, we're not just talking about the constitution document itself. There are actually several sources that contribute to the body of constitutional law. Let's break them down.
The 1999 Constitution
This is obviously the main source. It's the actual document that was adopted in 1999 and has been amended several times since. This constitution replaced the previous ones we've had (we've had quite a few throughout our history as an independent nation). The 1999 Constitution lays out the structure of our government, establishes the three branches, defines the federal system, enumerates citizens' rights, and sets out the procedures for everything from elections to impeachment. When lawyers or judges talk about "the Constitution," this is usually what they mean.
Court Decisions AKA judicial precedent (Case Law)
Our constitution document itself doesn't answer every question. Sometimes the wording is unclear or different provisions seem to conflict with each other (creating problem of ambiguity). That's where courts come in. When judges interpret constitutional provisions and apply them to specific cases, those interpretations become part of constitutional law. The Supreme Court's decisions are especially important because they're the final word on what the constitution means. Once the Supreme Court interprets a constitutional provision a certain way, that interpretation is binding on everyone until either the constitution is amended or the Supreme Court changes its mind (which rarely happens) especially in rigid type.
For example, there have been important cases about what exactly "freedom of expression" means. Does it cover hate speech? What about false information? The constitution says you have freedom of expression, but the details get worked out through court cases. These judicial decisions collectively form a huge part of constitutional law.
Constitutional Conventions
Now we're talking about rules that aren't actually written in the constitution or any law, but everyone follows them anyway. These are conventions – practices that have become established over time and that political actors generally respect. They're not legally enforceable in court, but they're still important.
Here's an example: the Nigerian constitution says the President should appoint ministers, but it doesn't explicitly say he must appoint at least one minister from every state. However, there's a convention that this should happen. Presidents generally follow this convention even though nobody could take them to court if they didn't. Another example might be certain procedures followed during budget presentations or how government business is conducted. These conventions help the system run smoothly even though they're not in the written law.
Statutes and Other Laws
Some regular laws help implement constitutional provisions. Take the Electoral Act, for instance. The constitution says there should be elections and sets out some basic requirements via what is called electoral system, but the Electoral Act fills in the details – how elections should be conducted, how votes are counted, what happens if there's a dispute, and so on. These laws aren't part of the constitution itself, but they're closely connected to constitutional law because they give effect to constitutional provisions.
Customary and Islamic Law
In certain areas, particularly relating to personal matters like marriage, inheritance, and family issues, customary law and Islamic law can form part of the constitutional framework. But there's a crucial limitation – these laws can only apply to the extent they're not inconsistent with the constitution. So if a customary practice violates someone's fundamental rights as guaranteed by the constitution, the constitution wins. The constitution is supreme over everything else, including traditional practices.
Why this is important to students
You might be wondering why you need to know all this detail about constitutions and constitutional law. Well, here's the thing – the constitution affects literally everything in the legal system. When parliament wants to pass a new law, they have to make sure it's constitutional. When police arrest someone, they have to follow constitutional procedures. When you go to court, you have constitutional rights. When the government wants to build a road through your property, constitutional law determines whether they can do that and how they must compensate you.

Knowing the constitution also helps you understand politics better. When politicians argue about states' rights versus federal power, they're really arguing about constitutional interpretation. When people talk about free speech controversies, they're talking about how to balance constitutional rights. When there's debate about whether the president has exceeded his authority, the constitution is what determines the answer.
Wrapping Up
So let's recap what we've covered. We've looked at what a constitution is and why it matters. We've explored the different types – written versus unwritten, rigid versus flexible, federal versus unitary. We've discussed what makes a constitution good, including principles like supremacy, separation of powers, protection of rights, rule of law, and the balance between stability and adaptability.
We've also examined the various sources of Nigerian constitutional law. Yes, the 1999 Constitution is the big one, but don't forget about judicial decisions that interpret it, conventions that supplement it, statutes that implement it, and in some contexts, customary and Islamic law that operate within its framework.
I rest my case on this topic
The constitution really is more than just a legal document. It's the foundation of everything in our legal and political system. If you're serious about understanding law, you can't just memorize what the constitution says. You need to understand the deeper principles, how the different parts fit together, and how it actually works in practice.
The constitution governs how the government operates, but it also defines the relationship between the state and individual citizens. It's what gives law its legitimacy and authority. Without it, we'd just have whoever is strongest making up rules as they go along. The constitution is what makes a system of laws possible in the first place.
As you continue studying law, you'll find that constitutional law keeps coming up, no matter what area you're interested in. Criminal law? Constitutional rights of the accused. Property law? Constitutional provisions about property rights and eminent domain. Contract law? Constitutional principles about freedom of contract. It's everywhere. So getting a solid foundation in constitutional law isn't just helpful – it's absolutely essential.
Questions to Think About
To help you process all this, here are some things worth thinking about or discussing: What exactly is a constitution and why is it so important in a legal system? How does a rigid constitution differ from a flexible one, and can you give examples of each? What are the main sources of constitutional law in Nigeria? Nigeria's constitution is described as both rigid and federal – what does this mean and what are the implications? What characteristics should a good constitution have, and why does each characteristic matter?
Where to Learn More (, References)
If you want to dig deeper into this topic, there are lots of good resources out there. Obviously, start with the actual Constitution of the Federal Republic of Nigeria from 1999 (as amended). Read it, even if it's dense – you need to be familiar with the actual text. There are also excellent books by Nigerian constitutional law scholars like B.O. Nwabueze, A.O. Obilade, and T.O. Elias. Look up important Supreme Court cases too, like Attorney-General of the Federation v. Attorney-General of Lagos State from 2003. These cases show you how constitutional principles actually get applied in real situations.
The constitution is living law. It's not just history or theory – it's shaping what happens in Nigeria right now, today. Understanding it is understanding how power works, how rights are protected, and how the legal system functions. That's why we spend so much time on it in legal education, and why you should take it seriously in your studies.
