Why should the judiciary be independent?

The judiciary must be independent and must not submit to any outside influence.
The independence of the judiciary is expressed in the independence of the judges themselves, who make decisions.
Judges, according to the Constitution, are independent and are subject only to the law. In their decisions, they must follow only the Constitution and the law. There should be no contradictions with the Constitution in court decisions. Since the Constitution is the main law and the main principles and rules of life in our country are spelled out in it.
