In a democratic society where the governed relinquish a portion of their autonomy, the legal system is the guardian against abuses by those in positions of power. Citizens agree to limitations on their freedom in exchange for peaceful coexistence, and they expect that when conflicts between citizens or between the state and citizens arise, there is a place that is independent from undue influence, that is trustworthy, and that has authority over all the parties to solve the disputes peacefully. The courts in any democratic system are that place of refuge. U.S. Supreme Court Chief Justice William Howard Taft stated in 1926 that "the real practical blessing of our Bill of Rights is in its provision for fixed procedure securing a fair hearing by independent courts to each individual."

A fundamental value in the American system of justice is that the stability of the society depends upon the ability of the people to readily obtain access to the courts, because the court system is the mechanism recognized and accepted by all to peacefully resolve disputes. Denying access to the courts forces dispute resolution into other arenas and results in vigilantism and violence.

The judicial systems of the United States are structured to ensure access to the courts and equal justice under law for all citizens. The U.S. Constitution and the constitutions of all 50 states contain specific articles on the judicial branch. The judicial systems of the United States are separate, coequal branches of government that maintain autonomy through their own structures, authorities, and rules. The principle of judicial independence, reflected in the federal and state constitutions and in American legal and political history, allows judges to make decisions based on the law and the facts of each case, rather than on popular opinion or political considerations.

The judicial systems of the United States include the federal courts and separate court systems for all 50 states, the District of Columbia, and five territories. These different court systems handle approximately 100 million cases per year, with the vast majority being heard in state courts. At the federal level, approximately 2,200 judges serve across the United States in the following capacities: justices of the Supreme Court, judges of the courts of appeals, judges of the district courts, bankruptcy judges, and magistrate judges. At the state level, approximately 31,000 judges serve on the bench, from the highest court down to local courts of limited jurisdiction.

Each state and territory has the authority to establish and operate its own court system. The structure of state court systems varies from state to state. Some states have "unified," or simplified, systems of only two or three levels, while others have multiple levels of court for different types of cases. Judges are selected by a variety of different methods in the states, including appointment by governors, popular election, and selection by the legislature. Terms of office for state judges range from four years to lifetime tenure.

When discussing the idea of access to the courts, mere access in the theoretical or legal sense is not enough; rather, it is the results that flow from the decisions made by the courts that give it meaning. For example, the value of "access" is evident when the courts decide that no one, especially those in positions of power, is above the law, or when access requires the right to counsel in cases where one's liberty is in jeopardy.

The practical application of the fundamental right to access the courts under the U.S. Constitution has been put to the test throughout the nation's history. It has been claimed and challenged by many.

Perhaps the importance of open access to the courts is best recognized in the criminal justice sector in cases involving the right to counsel. In the United States it has been established that, at least in criminal matters involving the loss of liberty, a person cannot be considered to have adequate access to justice unless the person is provided with legal counsel.

An impartial, independent judiciary is the guardian of individual rights in a democratic society. In order for citizens to have faith in their court system, all people must have access to the courts when necessary.

Real and meaningful access to the courts is fundamental to the health and vitality of any democracy. It is the shield used by citizens to protect themselves against tyranny, abuses, and simple errors in judgment. Access to the courts is the lifeblood of the system because from it flow all other rights. It helps preserve order when conflict arises and keeps citizens actively participating in the proper use of their collective power.
