Exploring the sources of legal authority

We all know that laws are created to ensure orderly and fair societies. What you may not know is how these laws are determined in the first place. This week, we explore the sources of law and how they influence jurisprudence – the study of law and its application. Many factors go into determining which rules govern our lives, so let’s take a closer look at some of the most important ones.


There are three main sources of law in jurisprudence: legislation, precedent, and custom. The first two are created by lawmakers and judges, while the people themselves create the third. Each has its advantages and disadvantages, which will be explored in this post.

Legislation is made by lawmakers, who create laws that everyone within that jurisdiction must follow. The advantage of legislation is that it is clear and concise – everyone knows what the law says and what they need to do to comply with it. The disadvantage of legislation is that it can often be inflexible, not taking into account changing circumstances or new developments.

How do sources of law influence court decisions?

When a person goes to court, they expect the decisions will be based on the law. However, many people don’t realize that the sources of law can play a big role in how a court makes its decisions. There are three main sources of law in the United States: statutes, common law, and administrative law. Each of these sources has a different set of rules that courts must follow when making decisions.

When a court is tasked with making a decision, it will look to various sources of law to help guide its ruling. The three most common sources of law are statutes, case law, and regulations.

Statutes are laws that the legislature has passed. Case law is created when courts issue rulings in cases before them. Regulations are rules that government agencies have issued.

Each source of law can play an important role in a court’s decision-making process. Statutes guide what the law is supposed to be, while case law establishes how the law should be interpreted and applied in specific situations. Regulations can provide information on how government agencies interpret and enforce the law.
