A Short Summary of Article III

The people at the Constitutional Convention wanted a justice system, so they created Article III about the judicial branch. Article III was ratified on September 17, 1787 along with the rest of the Constitution. This article states that the judicial branch is headed by the Supreme Court and made up smaller courts within the states. It tells us that the judges of the Supreme Court shall hold their office for life or under good behavior. They have the power to look at laws made by Congress to see if they are Constitutional or not. This is called judicial review. The judges can also force ambassadors to resign upon what they have done.
Another thing that they can do is punish citizens for treason. Treason is when a citizen gives aid or comfort to their country's enemy. Someone accused of treason will be punished but the court cannot punish their children. This is Article III's purpose.
