Why the judiciary is important in a democracy?

An independent judiciary is important to maintaining our democracy. One reason is so that impartial judges can check the legislature and president and prevent them from passing unconstitutional laws. This is democratic because an impartial judge is unbiased, and makes decisions based on what the law states not based on whether or not they believe it is right based on their ideologies. They also are not pressured politically to decide one way or the other. For example, if Congress wanted to pass a bill saying that only Christian people can worship in public in the United States, even though a judge may believe that this law should be implemented, they would rule this unconstitutional because it is in violation of Article 1.
