More About Judicial Branch

What is the judicial branch?

The judicial branch is the branch of government responsible for interpreting laws and applying justice.

In the United States, the federal and state governments are divided into three parts—the legislative branch, the executive branch, and the judicial branch. For the federal government, the branches are established by the Constitution of the United States. At the state level, the judicial branch is established either by the state legislature or by a state constitution.

In general, the judicial branch at both the federal and state level has two very important jobs. The first is to settle disputes regarding laws, while the second is to ensure citizens are treated fairly under the law. This is done through the justice system and involves many courts, lawyers, and judges.

Federally, the highest court in the land is the United States Supreme Court. With a few exceptions, this court only hears appeals that involve a dispute with how the Constitution is interpreted. Every lower court in the country must comply with the rulings of the Supreme Court.

Through the system of checks and balances, the judicial branch can check the power of the other two branches of government and has its own power checked by them. Federal judges are appointed by the president (executive branch) and approved by Congress (the legislative branch). On the other hand, the Supreme Court has the power to declare a law as unconstitutional, which can severely limit the actions of both of the other two branches.

US states are free to organize their own versions of the judicial branch. In general, the states usually have a state supreme court, a start court of appeals, and lower courts that descend all the way down to municipalities, such as cities and towns.

Why is the judicial branch important?

In the United States, the federal judicial branch was established by Article III, Section I of the Constitution, which was written in 1787 and ratified in 1788. While the Constitution doesn’t use the term judicial branch specifically, this term has long been used to refer to the American court system.

The Constitution doesn’t go into as much detail on the structure of the judicial branch compared to the other two branches. While the Constitution requires a national Supreme Court, it lets Congress decide on the number of judges (justices). Additionally, it allows Congress to decide how the entirety of the rest of the federal court system should be organized.

Today, the judicial branch impacts all Americans in one way or another. If you commit a crime, you are guaranteed a fair trial by the criminal courts. If you have been wronged by someone or by an organization, you can file a lawsuit, which will be resolved by a civil court.

Federally, the judges of the judicial branch are appointed rather than elected.
