Sources of law

Laws are the rules that help a country govern its land. We call the places where these rules begin "sources of law."

The idea is very old. A man named Cicero used the word "fountain" to describe law in Rome. Today, a source of law is anything that can create or change a rule. Some people think a source is just the person in power. Others say it is the reason why a law is valid. Legal experts often group these sources into two main types. Formal sources are the things that actually make the law, like statutes or contracts. Material sources are the places where you can find those laws, like a newspaper or an official bulletin.

Law can work in many different ways. Some laws come from the actions of people. This is called legislation. A group called a legislature writes these rules. They can make new laws or change old ones. In the United Kingdom, the Westminster Parliament does this. In many nations, a written constitution is the most important source. However, a legislature can sometimes change a constitution if they follow special rules.

Other laws come from judges. This is called case law or judicial precedent. Judges look at how similar cases were decided in the past. This helps them make fair choices today. This system is often called common law. It allows the law to grow and change as the world changes.

History shows us that laws come from many different places. Long ago, some laws were not even written down. These were called customs. If people followed a tradition for a very long time, it could become a law. Some laws also come from religious practices. These rules come from sacred texts or religious doctrines. In the past, some leaders believed in the "divine right of kings." This meant they thought God gave them the power to rule. Over many years, new ideas like human rights and civil rights became important sources of law. Even after World War II, people learned that following orders was not an excuse for breaking universal standards of right and wrong.

Different parts of the world use different legal systems.

Some places use a "civil law" system. In these systems, people rely heavily on written legal codes. For example, the state of Louisiana uses a civil code. Other places use a "common law" system. Some countries even mix these styles together. Scotland and South Africa are examples of "hybrid" systems. They use a mix of common law, civil law, and tribal law. There is also international law. This is when different countries make agreements called treaties. For a treaty to work, many countries must sign it. The Maritime Labour Convention is an example. It started working in 2013 after many countries signed it.

Law also connects different groups of people and nations. The European Union is a special example of this. When nations join the EU, they adopt many shared rules. These rules are made by groups in Brussels. These groups include the European Commission and the European Parliament. They work together to make decisions that affect many countries. In England, there is also something called "equity." This is a special type of law that helps make things fair. It was once handled by a specific group called the Court of Chancery. Today, the law continues to be a living thing. It moves from old traditions to new rules made by modern governments.
