Quotes: "Where the Executive and Legislative branches are elected by the people, members of the Judicial Branch are appointed by the President and confirmed by the Senate."
"The Supreme Court rules whether something is constitutional or unconstitutional—whether or not it is permitted under the Constitution."
Explanation of Connection: The Judicial Branch consists of the Supreme Court, which explains the meaning of the Constitution and laws passed by Congress. The main role of the judicial branch is to interpret laws created by the legislative branch, and passed by the executive branch.
In my opinion, it's best for the judicial branch to inforce laws and decide whether or not something is constitutional. The head of the judicial branch is the Supreme Court, courts make the final decision as to if someone should be sent to jail, receive the death penalty, or be set free. Inforcing laws will help the citizens obey the constitution and law, and stay out of trouble; most people would rather not go to jail or be sentenced to death because they value their lives.
