Constitutional Law deals with the interpretation and implementation of the United States Constitution. As the Constitution is the foundation of the United States, Constitutional Law deals with some of the fundamental relationships within our society. This includes relationships among the states, the states and the federal government, the three branches (executive, legislative, judicial) of the federal government, and the rights of the individual in relation to both federal and state government. The area of judicial review is an important subject within Constitutional Law. The Supreme Court has played a crucial role in interpreting the Constitution. Consequently, study of Constitutional Law focuses heavily on Supreme Court rulings.
