In order to ensure judicial independence, apart from the separation of powers and the establishment of a judicial system, the United States also has a relatively complete jury system. The jury system was initiated by the British. It promoted the civilization of British society. As a British colony, the United States also introduced this system. The so-called jury system is to invite a number of citizens to form a jury at any time and temporarily grant them the right to participate in the trial. Jurors can be nobles or civilians, but not government officials. The jury system has been put in place, and these citizens refer to the status of judges. In this way, the power to lead society can be in the hands of the people or these citizens. Members of the jury are citizens of ordinary unincorporated persons. They usually don't have much legal background and professional knowledge, and rely on common sense to judge complex legal issues beyond their professional level. The jury will listen to and observe the testimony of witnesses, and check all the photos or physical evidence of the case and the evidence provided (such as drugs, guns or other physical evidence related to the crime). Then, the judge will read and verify the legal provisions applicable to this case to the jurors, and send a copy to the jurors.

For example, the legal definition of the crime of illegal possession of drugs is that the defendant holds any amount of drugs. Introduce some legal provisions to help the jury understand their work. At the same time, the court helps jury members fully understand their work before and during the trial. If some of them have doubts about their work, the court will encourage them to ask the judge, whose duty is to ensure that jurors are qualified for this position. At this time, if jurors have any legal questions, they can ask the judge to clarify and answer their questions. A jury usually consists of 12 people. In the final verdict, all 12 members of the jury must make a decision of guilt or innocence. However, in some cases, the jury cannot reach a unanimous verdict, which is called pending, which is usually rare.

Therefore, the jury system seems to limit the judicial power on the surface, but in fact it is strengthening the judicial power. Because the people share the power of judges, the judges in the country are stronger. Relying on the implementation of the civil jury system, the United States enables judicial personnel to infiltrate the spirit of the rule of law into the lowest level of society. The jury system is the most powerful means to enable people to rule, and it is also the most effective way to enable people to learn to rule. In this way, the government's intervention in judicial justice is avoided and judicial justice is guaranteed.
