Sources of American law

There are four sources of American law: Constitutional law, Administrative law, statutory law, and case law. In this discussion, I would like you to come up with you own example of each. In other words, your discussion should look like this:

Constitutional Law: All citizens born or naturalized in the United States are citizens of the United States and the State wherein they reside.

Statutory Law: The speed limits in the state of Pennsylvania are determined by the state.

Administrative Law: FCC regulations prohibit broadcast television networks from airing certain language/words (you know what I mean).

Case Law: Brown v. Board of Education is a Supreme Court case which essentially ended segregation in public schools.
